Unlock bootloader xiaomi. Xiaomi – bootloader unlocking. Bugs and problems

You've probably repeatedly looked through the forum and seen a lot of custom firmware; you may have previously installed them on smartphones. You can install new software on some devices without any problems, but sometimes difficulties arise with others. For example, on some Xiaomi smartphones, if the Bootloader is blocked, you will not be able to install custom firmware. People often ask on the forum how to unlock the bootloader of xiaomi redmi note 3 to install unofficial software. On this device, as well as Note Pro, Redmi 3s and some other devices (released since November 2015), the manufacturer locks the bootloader, so in order to fully control the smartphone you must first remove the lock from the Bootloader.

If you are a confident Android user, then you know for sure that an unlocked Bootloader provides a number of advantages to the user:

Ability to install custom Recovery.
The modified Recovery makes working with the device much easier. Thanks to it, it becomes possible to install any firmware and additional scripts.
With the bootloader open, you can easily set Root rights (superuser). They are needed to work with system files. With Root rights, you can customize the device for yourself: remove unnecessary standard programs, clear your smartphone of ads, overclock the processor, increase battery life, and so on.

Let's say you decide to install modified firmware. First you need to check the status of the bootloader.

How to find out if the bootloader is locked

There are several ways to find out this information. Let's start with something simple.

Method 1 - via smartphone

This check is relevant for Redmi 3 and Redmi Note 3, but it is possible that it will work on your model.

Go to the system settings of the device;
Select the bottommost item “About device”;
Click on the “Kernel” line quickly several times;
In the menu that appears, go to the first item “Software version”.
We find the line “fastboot lock state” under which the bootloader state is indicated: lock – locked, unlock – unlocked.

Method 2 - via computer

If you have Windows

Boot the device in fastboot mode. Press the power button and the lower volume key simultaneously. We connect the smartphone via USB to the computer. On a PC, press the Win+R keys and an input field will open. Enter the command “cmd” to open the command line. In the command line, write the command “adb” and press Enter. Find out information about the bootloader. We type the command:

fastboot oem device-info

If the bootloader is unlocked, the display will show: Device unlocked: true.
Otherwise, the value false will be specified.

For linux

Suitable for Linux-like OS (ubuntu/debian).

In the terminal we write adb - sudo apt-get install android-tools-adb android-tools-fastboot
Enable fastboot on your smartphone (power and volume down button)
sudo fastboot devices, a number should appear - this is your device
sudo fastboot oem device-info, bootloader status should be displayed

If you see a message< waiting for device >, which means the command was not executed as an administrator.

Step-by-step unlocking instructions

Be sure to back up any necessary information. After unlocking, all information can be deleted!

Getting permission

To unlock Bootloader, you must obtain permission from the manufacturer. To do this, we go to en.miui.com/unlock, press the only button there. This link will open the English version of the site; if it’s in Chinese, look at the screenshots. We follow the further instructions:

Unlocking the xiaomi redmi bootloader begins with authorizing your account. Enter your email address, password and log in.

It happens that some users immediately go to the download page for the unlocking utility, while others need to fill out another form:

Enter your full name or just your name;
Select country;
Specify phone number
Reason for unlocking.

The data must be entered in English if the English version is opened, if the language is Chinese, then everything is in Chinese, it is worth using a translator. In the “Reason” field, you can enter the following: “I want to install firmware with Russian language on my xiaomi mi4 smartphone.” We indicate our own phone model.

We tick the box, agree to the terms, and confirm.
An SMS will be sent to your mobile phone with a confirmation code, which you must enter in the text input field, then click “Next”.

At the last stage, you will see a notification that your application has been successfully submitted. The processing time can be three days or more than a week. It is recommended to check the status of the application on the website, since not everyone receives an SMS notification.

We inform you that the method is official, however, on some devices, minor problems may arise during unlocking. Often reinstalling the drivers solves the problem.

Unlocking

To unlock, the official weekly (developer) firmware must be installed - China Developer Version.

For Xiaomi redmi 3 pro and Xiaomi Mi5 you can use the global firmware version - Global Developer Version.

Mi4c and Mi Note Pro smartphones already have an UNLOCKED bootloader, which will be blocked when updating to new versions of miui. Therefore, we specifically install the China Developer Version (released only after April 2016) for blocking and then unlock it using the official method.

All these firmwares are official; you don’t need unlocking or other tricks to install them.

Let's say we have waited for the bootloader to unlock, now let's begin the process:

If you want to immediately install unofficial firmware after unlocking, then download it in advance and place it in the device’s memory.
Download Mi Flash Unlock, this is an unlocking program. On the Xiaomi Redmi Note 3 Pro device, we need to unlock the bootloader (unlock the bootloader) using the first-time removal program .
Turn off the gadget, hold down the power button and the volume key (lower) at the same time to switch to Fastboot mode.
We connect the device to the computer.
We go to the Mi Flash Unlock utility, we see a window with the heading “Disclaimer”, we agree with the rules.

Enter personal data (Mi ID and password). Click the “Login” button.

We wait until the program detects the smartphone, then press the final “Unlock” button.

If the operation was successful, then Bootloader is now in unlocked mode.

All that remains is to install custom Recovery, with which we can install the firmware downloaded in advance into the device’s memory.

How to increase the chance of unlocking approval

When considering your request for unlocking, Xiaomi will check all information about your account. Many accounts are not given the right to an open Bootloader at all, while others wait a month for a response.

To speed up the process, you need to register on the official xiaomi forum and participate in it. We come up with a username, password, and communicate with people, just like on any forum. Your account information will necessarily contain information that you are an active member of the forum. Employees love such users, so they give them the right to unlock the bootloader.

For some very active accounts, as well as those who are members of various development groups, permission is given instantly and automatically. You can understand that you are “the chosen one” by the fact that after submitting your application, you are immediately redirected to the program download page.

How many devices can you unlock at once?

On the official website there are restrictions on the number of Bootloader unlocks. One account allows you to unlock one device once a month, after 30 days you can apply again for another smartphone. There is no way to bypass the restriction, since permission is given specifically for the account, and not for the smartphone itself.

Possible errors when unlocking

The process of removing protection stops at 50%.

The problem appears due to problems with Xiaomi servers. Just start the process again from time to time, you will definitely get lucky!

Stops at 50% with the message “Not connected Mi Phone”.

Reinstall device drivers.

Stop after the second step.

It is necessary to change the firmware version. Most likely you have a stable version. Only versions 5.x.x or 6.x.x are suitable.

The SMS with the confirmation code does not arrive or a Chinese inscription appears. Most likely the quota for Russia has ended.

Use a Chinese VPN or change your number.

A message appears: “Your device isn't supported by Mi Unlock.”

There is a problem with your firmware, you need to change it.

The green button cannot be pressed

Allow your browser to display pop-ups

Can't log into Mi account

In the login field, enter your account id number, not your phone number

After authorization, it constantly asks you to indicate your nickname.

The refusal comes within 10 minutes.

This is a glitch of Xiaomi servers. Reapply.

A Network Error appears.

The problem is on Xiaomi's side. Clear cookies (temporary files) in your browser, change IP, use VPS. If you have Beeline, then log in through another provider.

If refused or the wait is more than a month

Recently, Xiaomi has stopped refusing to unlock. But if you receive a refusal, then do not despair, follow our instructions.

There are several options:

We wait 15-20 days and re-apply.
Create a second account and submit an application.
We contact support.

Let's look at option 3 in more detail. Write a letter in English and send to [email protected]. The subject of the letter should be “Unlock Your Mi Device”. You will receive a response letter asking for your information. Copy the template they sent, fill in your details and send it to them. The permit is sent in about a day or even earlier.

If for some reason you are refused and nothing helps, which is equal to a 0.001% chance, then you can use a trick.

We switch to Parental Control mode and contact technical support called “Mi Customer Service for Europe”. We write that we cannot exit this mode (this is a popular problem). I will offer you different methods, always answer what did not help. As a result, you may be asked to unlock your device to solve this problem, or you may gently ask about it. There is a high probability that they will then ask for your data and unlock it.

Results

Users who have been unable to install custom software for a long time will now be able to fix this problem. In our article, we described in detail how to unlock the bootloader of a Xiaomi Redmi 3 smartphone using a special utility in the official way. It is also suitable for other Xiaomi models. We hope this article answers all your questions. Write your reviews in the comments.

Many owners of Chinese phones sooner or later wondered how to check whether the Xiaomi bootloader is unlocked. Often, users begin to delve into such details because some devices from this company do not allow them to be reflashed. It is also inconvenient that when buying a phone directly from China, the consumer will not be able to change the operating system to a Russified or other localized system in the future due to closed access to the bootloader.

Of course, a completely logical question immediately arises: “Why doesn’t the manufacturer support the use of its equipment in all corners of the Earth?” Or maybe he is trying to introduce Chinese into wider use? Of course, this is not true. This happens because it has become popular to counterfeit phones and official firmware from Hiomi. The fact is that the software can contain a huge number of viruses that can collect data from the phone. This is why all official devices do not allow you to change the firmware. In this article we will look at how to unlock the Xiaomi bootloader.

Another reason why the bootloader is locked

There is another good reason why the Chinese manufacturer prefers to block access to the bootloader. If suddenly a consumer’s phone is stolen or he loses it, then due to the blocking, the new owner of the device will not be able to reflash it and obtain data and personal information. Moreover, each gadget has its own Mi account. Although it is worth admitting that scammers also often wonder how to unlock the Xiaomi bootloader. And, most likely, they have the necessary skills. In the latest versions of the original software, you can notice new options. One of them has a function that allows you to locate your phone or tablet. The second is responsible for sending absolutely any text to the device’s working screen.

How to determine if the bootloader is locked via PC?

Most often, users encounter this problem when working with the Xiaomi Redmi Note 3 Pro phone. Unlocking the bootloader will be easy. However, this process will take from a week to a month.

In order to find out whether the bootloader is unlocked or not on any phone from the Chinese manufacturer "Xiomi", you need to go into a mode called fastboot. You must first connect the device to the computer. After this, you need to write the word “run” in the Start menu. Using it we go to the command line. We enter the letters adb and write a special phrase there. As a rule, it is the same for each phone and looks like this: fastboot oem device-info. After this, one of the inscriptions will appear on the screen: true or false. The first option indicates that the bootloader is activated, and the second option indicates that it is not unlocked.

If it does not work, then you must immediately say that it will be difficult to obtain Root rights, even if they have already been activated previously. The fact is that if the initial version of the firmware does not have a locked bootloader, it may become so after a software update. In order to do this, you will have to use a special PC Suite program. Moreover, the update process cannot be carried out via Mi Flash. Therefore, in order to use the usual functionality, you will have to return everything to its original position. The article describes ways to unlock Xiaomi bootloader.

Find out about the bootloader status using your phone

The described method works for Redmi and Redmi Note 3 phones, but may not work for others.

You need to visit system settings. There it is easy to find the “About device” item. We need to find the column in the “Kernel” menu that is responsible for the system version. It will say either “Blocked” or “Unblocked” in English.

Preparation

Before you begin the process of unlocking your device, you must visit the official website and obtain special permission for this action. The resource address is quite easy to find on the Internet, and there a special section that is responsible for activating the bootloader immediately catches your eye. What needs to be done? We offer step-by-step instructions for consideration.

Step one

It’s still too early to move on to instructions regarding that. The first thing you need to do is log in to the site.

Sometimes it happens that the account already has permission to unlock. In this case, you should scroll a little further and proceed to the next part of the solution to the problem. If not, then move on to the second step.

Step two

Next you need to fill out a form. This must be done in English, others are not accepted. If you have any difficulties, you can use any translator. The main thing is not to confuse the information and fill everything out correctly.

Attention! The site may open in the Chinese version. In this case, you need to select English at the bottom of the page.

After filling out, you need to click on the checkbox, which confirms your consent to the use of data.

Step three

The easiest step and not labor intensive. It consists of entering the code on the next page after filling out the form. The numbers will be sent as a message to the mobile phone number specified earlier.

Step four

Consists of waiting for a response from the company. According to the rules, it should arrive 2-10 days after applying, but consumers say it could be sent much later. But you still need to wait for an answer and only then begin to act.

If you wish, you can always check the degree of consideration of your application on the official website.

Preparing to unlock

After the company has responded positively to the request to unlock the bootloader, you can begin the process itself. It is not labor intensive and is universal. It doesn’t matter at all which phone from Hiomi we are talking about, because the method is the same for everyone, there are no differences.

Step one

The first thing you need to do is download the latest version of the Recovery software. You need to be careful when selecting, as updates occur every week. The file should be placed in the internal memory of the device.

Step two

You need to go to the menu responsible for updating and find the column about downloading a new firmware version. This is where you should place the downloaded software file. Since changing the firmware will delete all information and data from the phone, it is advisable to perform a backup (or so-called backup).

Step three

After updating the firmware, you need to use the Mi form, and then log in using the same login where you received permission to unlock. After this, you need to download a special Flash Unlock program. It is an important nuance in the question of how to unlock the bootloader of Xiaomi Redmi 3 Pro, as well as in other modifications of the device.

Step four

You should turn off the phone and hold down the power and volume down buttons. You must hold them until Fastboot mode turns on. Next you should move on to the fifth step.

Step five

You need to connect your phone to your computer using a USB cable. After this, launch the previously downloaded program. In it, before starting the process, you must confirm the waiver of claims against the company if something happens after activation and subsequent installation of localized firmware. When wondering how to unlock the bootloader of Xiaomi Redmi 3 and other phones from the manufacturer, you need to understand all the risks.

Step six

You need to log in to the program by entering your identification number and password. Next, you should wait until the corresponding message appears that the device is connected. The “Unlock phone” button is activated, which you need to click on.

Step seven

At the beginning of the description of the steps that will help you learn how to unlock the bootloader of Xiaomi Redmi Note 3 and all other devices from the manufacturer, it was stated that the process itself is quite fast. And this is true. 10 seconds after pressing the button, the bootloader will be unlocked. Now the user can get administrator rights, accept updates and install them in easy accessible ways.

It is worth noting that from one account you can unlock no more than one device per calendar month.

Refusal to unlock request

What to do if the response received a refusal to unlock? You need to submit another one. This can be done on a special forum, which is located on the official website. Let's take a step-by-step look at how to proceed next. Another approach may help you get permission to unlock the bootloader of Xiaomi Redmi Pro and all its modifications.

Step one

You need to register on the forum. This time registration is carried out not by phone number, but by email address. The form is quite simple, so there shouldn't be any problems.

Step two

After filling out the form and submitting it, the robot will inform the user that they need to confirm their email address. The letter arrives quite quickly. After the user follows the link in it, he must click on the “Activation” button. Then the Chinese version of the profile will open.

Step three

You need to find the “Unlock” menu and go to it. There the system will ask you to come up with your own nickname, which will be displayed on the forum next to the comments. It can consist of both numbers and Latin letters.

Step four

After this, the familiar page will open where you need to fill out an application to activate the device. How to correctly indicate the information and how long to wait for a response and how to unlock the Xiaomi bootloader is described above. Most likely, this time the verdict will be positive.

Indication of reasons for unlocking?

This statement must be written as fully and openly as possible. You should not copy phrases in English or Chinese “Please unlock your device,” otherwise the chance of refusal increases many times over.

You should not justify your need for this action only by installing firmware. It is best to add a few additional words about obtaining Root rights, which will allow, for example, to lose dangerous viruses from the phone system.

You can describe all the reasons in detail and as accurately as possible, and translate them into English through online services. There is no need to interpret the text into Chinese. It would be good to clarify that the user understands all the resulting risks that arise after unlocking.

Results

People who are concerned about how to unlock the bootloader of Xiaomi Redmi and all its modifications will now be able to fix the problem they have received. After completing the process, you can freely install custom Recovery, localized firmware, and so on. The article describes the official method of unlocking the device, which copes with its task in 90% of cases.

Before flashing any Android device, some preparatory procedures are required. If we consider the issue of installing system software in Xiaomi devices, in many cases it is necessary to unlock the bootloader. This is the first step towards success during the firmware and obtaining the desired results.

Without delving into the reasons why Xiaomi began to block the bootloader in devices of its own production at a certain period of time, it should be noted that after unlocking it, the user gets a lot of opportunities to control the software part of his device. Among these advantages are obtaining root rights, installing custom recovery, localized and modified firmware, etc.

Before you begin manipulations to unlock the bootloader, even in the official way approved for use by the manufacturer, you should consider the following.

Responsibility for the results and consequences of operations carried out with the device lies solely with its owner who carried out the procedures! The administration of the resource warns that the user performs all actions with the device at his own peril and risk!

The manufacturer Xiaomi provides users of its smartphones and tablets with an official way to unlock the bootloader, which will be discussed below. This requires only a few steps and has a positive effect in almost all cases.

It is worth noting that enthusiasts have developed and are quite widespread in unofficial methods for bypassing the blocking for many devices, including Xiaomi MiPad 2, Redmi Note 3 Pro, Redmi 4 Pro, Mi4s, Redmi 3/3 Pro, Redmi 3S/3X, Mi Max.

The use of unofficial methods cannot be considered safe, since the use of such solutions, especially by inexperienced users, often leads to damage to the software part of the device and even “bricking” the device.

If the user has already decided to make a serious change to the software of the device released by Xiaomi, it is better to spend a little more time unlocking it using the official method and forget about this issue forever. Let's look at the unlocking procedure step by step.

Step 1: Check Bootloader Lock Status

Since Xiaomi smartphones are supplied to our country through various channels, including unofficial ones, it may well happen that unlocking the bootloader is not required, since this procedure has already been performed by the seller or the previous owner, in case of purchasing a used device.

There are several ways to check the lock status, each of which can be used depending on the device model. A universal method can be considered following the following instructions:

Download and unpack the package with and . In order not to bother the user with searching for the necessary files and downloading unnecessary components, we suggest using the link:
Install Fastboot mode drivers by following the instructions from the article:

We put the device into Fastboot mode and connect it to the PC. All Xiaomi devices are switched to the desired mode by pressing a key on the switched off device "Volume-" and when you hold down the button "Enable".

We hold both buttons until the image of a hare repairing Android and the inscription appears on the screen "FASTBOOT".

Launch the Windows command line.

On the command line enter the following:

Depending on the system response displayed on the command line, we determine the blocking status:

Step 2: Apply for unlocking

To carry out the bootloader unlocking procedure, you must first obtain permission from the device manufacturer. Xiaomi has tried to simplify the process of unlocking the bootloader as much as possible for the user, but you will have to be patient. The application review procedure can take up to 10 days, although approval usually comes within 12 hours.

It should be noted that you do not need to have a Xiaomi device to apply. Therefore, you can do everything to gain full control over the software part of the device in advance, for example, while waiting for the device to be delivered from an online store.

Register a Mi Account on the official Xiaomi website, following the steps from the instructions:
To submit an application, Xiaomi has provided a special page:
Follow the link and press the button "Unlock Now".

Log in to your Mi Account.
After checking the credentials, the unlock application form opens "Unlock Your Mi Device".

Everything must be completed in English!
Enter the user name and phone number in the appropriate fields. Before entering the digits of the phone number, select the country from the drop-down list.

The phone number must be real and valid! You will receive an SMS with a confirmation code, without which submitting an application is impossible!
In the field “Please state the real reason...” You must provide a description of the reason why you need to unlock the bootloader.

Here you can and should show your imagination. In general, a text like “Installing translated firmware” will do. Since all fields must be filled in in English, we will use.

After filling out the name, number and reason, all that remains is to enter the captcha and check the checkbox “I confirm that I have read...” and press the button "Apply Now".

We wait for an SMS with a confirmation code and enter it in a special field on the verification page that opens. After entering the numbers, press the button "Next".

Theoretically, Xiaomi’s positive decision regarding the possibility of unlocking should be reported via SMS to the number specified when submitting the application. It is worth noting that such an SMS does not always arrive, even when permission is received. To check the status, you should log in once every 24 hours.

Step 3: Working with Mi Unlock

As an official tool for unlocking the bootloader of your own devices, the manufacturer has developed a special Mi Unlock utility, the download of which becomes available after receiving approval for the operation from Xiaomi.

The utility does not require installation and to run it you only need to unpack the package obtained from the link above into a separate folder, and then double-click on the file miflash_unlock.exe.

Before proceeding directly to changing the status of the bootloader via Mi Unlock, it is important to prepare the device. Let's do the following step by step.
Upon completion of preparation, reboot the device into mode "Fastboot" and launch Mi Unlock without connecting the device to the PC yet.
We confirm awareness of risks by pressing a button "Agree" in the warning window.

Enter the data of the Mi Account entered into the phone and press the button "Sign In".

We wait until the program contacts the Xiaomi servers and checks for permission to perform the bootloader unlock operation.

After a window appears telling you that there is no device paired with the PC, we connect the device switched to "Fastboot" to the USB port.

As soon as the device is detected in the program, press the button "Unlock"

and wait for the process to complete.

Everything happens quite quickly, the procedure cannot be interrupted!

Upon completion of the operation, a message indicating the success of the unlock is displayed. Press the button "Reboot" to reboot the device.

Return Xiaomi bootloader lock

If Xiaomi provides an effective tool for unlocking the bootloaders of its devices in the form of the Mi Unlock utility, then the reverse procedure does not involve an official method. In this case, locking the bootloader is possible using .

To return the bootloader status to “locked”, you need to install the official firmware version via MiFlash in mode "clean all and lock" according to the instructions from the article:

After such firmware, the device will be completely cleared of all data and the bootloader will be blocked, i.e., the output will be a device “out of the box,” at least in software terms.

As you can see, unlocking the Xiaomi bootloader does not require any excessive effort or special skills from the user. It is important to understand that the process can take quite a long time, and to be patient. But after receiving a positive result, the owner of any Android device has all the possibilities to change the software part of the device for his own purposes and needs.

The article provides instructions for officially unlocking the bootloader using the example of a Xiaomi Redmi 4A phone.

First of all, to see if your device is locked, since the phone may already be unlocked and the steps below are not required. Go to the settings in the developer menu, open the "Bootloader status" item and look.

If the bootloader is locked, you cannot install custom firmware or root the device. Follow the steps below to unlock.

Go to the Bootloader Unlock Request page to apply. Create an account and log in to the site.

The site may ask you to come up with and enter a nickname for the forum.

Next, a form will appear where you need to indicate your name, country code, phone number, reason for unlocking the phone, enter the captcha, agree and accept the terms of the warning. The data must be filled out in English; if you do not have the necessary knowledge, use Google Translator. Do not try to copy reasons that are available on the Internet; copied reasons will most likely not lead to successful unlocking. Show professionalism. As an example, we wrote (in English) that we want to access system files so that (users of Xiaomi Redmi 4A and others are familiar with this problem).

After clicking the "Apply Now" button, an SMS with a code will be sent to your phone, which you must enter on the next page and click the green "Next" button.

In our case, we did not receive an SMS, but on the 5th day we went back to the unlock page under our account and instead of the request form we saw a large “Download Mi Unlock” button to download the unlock utility.

Download, unpack and run the unlocking program. Agree to the warning by clicking the "Agree" button and log in to your account.

In your phone settings, log in to your Mi account. If you registered using email rather than phone, click on “Other login methods.”

In the developer menu, activate the "Factory unlock" item.

Turn off the phone, then turn it on in "fastboot" mode: hold down the volume down key and the power key, the phone will turn on and a hare will appear poking around in the android.

Connect your phone to your computer with a USB cable. The program should automatically detect the device; if this does not happen, install the appropriate drivers. Click on the "Unlock" button and in the pop-up warning, confirm the action by clicking the "Unlock Anyway" button.

If all 3 checkboxes light up green, the unlocking has been completed successfully.

Click on the "Reboot phone" button to reboot your device. Visit the developer menu again to ensure your device is unlocked.

Unlocking errors and their solution

Current account is not bound to this device

Disconnect the USB cable, reboot the phone while holding the power button, wait for the system to boot, in the Android settings make sure that you are logged into your MIUI account (see above) and have provided all permissions. Reboot into fastboot and try to unlock your device again.

Couldn't unlock

Unlocking is blocked for 3 days (72 hours). Check if the Factory Unlock option is enabled (see above) and try again after 3 days.

If all else fails, try unlocking again.

We recommend using only the latest version of the "Mi Unlock" program, downloaded from the official website, since this software is updated very quickly and those versions that are available on the forums are very likely to not work.

Many people are interested in the question of how to unlock the Xiaomi bootloader, why it is needed and what benefits the user receives. After all, the procedure is quite complicated and multifaceted. Let's try to figure out what an unlocked bootloader will do, read the instructions, tips, advice and try to avoid possible problems.

ATTENTION! Important information about the bootloader. At the moment, the procedure for obtaining approval has been simplified. There is no need to fill out an application.

Download the program, link your Mi account to your phone in the settings (the developer is the bootloader status) and wait 360/720 hours.Go to the item “Unlocks via Mi Flash Unlock”!

Why unlock the bootloader?

Below we will talk about at least 3 reasons why you should unlock the bootloader on Xiaomi smartphones. But the most important reason is that you have a Chinese phone with MIUI China ROM in your hands.

Custom and localized firmware

The first and main advantage is the ability to install custom(unofficial) and localized(official, but with modifications specifically for your region) MIUI firmware. Some Xiaomi models accept third-party software, but in most cases, a locked Bootloader will not allow this. Now, in turn, let’s look at what custom firmware provides:

Richer functionality and advanced options that allow you to completely control the entire operation of your smartphone;
Installed root rights. Very often, unofficial firmware already has a “Superuser” mode.
Advanced and sensitive GPS navigator. The location is determined several times faster than on the standard version.
A highly optimized operating system kernel that either improves phone performance or increases battery life.

Modified Recovery (TWRP)

By unlocking the bootloader, you can easily perform CWM recovery, which is necessary not only to obtain root rights, but also for other important operations on your smartphone. Let's take a closer look:

Gives access to install new firmware;
Allows you to carry out easily and quickly, saving and leaving absolutely all data intact;
Many small new options, changes and improvements to existing functions;
Allow installation of batch zip archives;
Improved touch interface.

Root rights

First we need to download a special program Mi Flash Unlock(go to your model thread on the w3bsit3-dns.com forum, download from the link in the topic header, if you haven’t found it, write in the comments, we’ll send you the link). To avoid getting a virus on your device, it is best to download the application from the official Xiaomi website. You can choose the version of the utility yourself, but, of course, the latest update will be of the highest quality and most effective (you can download a localized version of the program on w3bsit3-dns.com, that is, in Russian).

It is advisable to put the folder with the program in the root of drive C, example: C:\MiFlashUnlock.

Step 1: Launch Mi Flash

Now open the Mi Flash program on behalf of administrator, we see a white screen with text in Chinese (if the localized version is like mine, then in Russian), where the disclaimer rules are indicated. We agree and click on the appropriate button.

Step 2: Login to Mi account

We are presented with a new window that requires you to log into your Mi account. Enter the password and ID, as they did in other situations. That is, there is nothing new, unusual or complex yet. We carefully check the specified data and keyboard layout, since it is at this stage that many users have problems with the appearance of such a notification: “You entered your password and/or login incorrectly.” Click “Login”.

Step 3: Connect your phone to PC

Then we return to the smartphone itself. Turn it off and transfer it to , simultaneously holding down the power and volume down keys. Using a USB cable.

Step 4: Unlock Process

The final final stage: the application begins to detect the smartphone and perform a lot of small necessary operations without our intervention. We wait a few minutes ( in my case 25 seconds), and if everything was done correctly, we receive a notification about successful unlocking - three green dots. Ready!

Bootloader unlock error: try again in 72 hours

ATTENTION! In 99% of cases, you will not be able to unlock your smartphone, as you need to go through additional verification.

If you receive a message like: " Binding time is too short, Less than 72 hours" or " After 360 hours of trying to unlock the device", please be aware that this is an additional verification of your account! That is, you must wait 3 days before repeating the procedure again. You won't be able to bypass the timer, just be patient, I went through it and so will you!

Important! At the time of writing, Xiaomi decided to increase additional verification for such models as: Mi5X, Redmi Note 5A, Redmi 5A Redmi 5/5plus, Mi Max. They got unrealistic 360 hour timer.

After you waited 72/360 hours, repeated the above procedure - did you get 3 green dots? Great! The bootloader is unlocked. Now proceed to installing extended recovery, that is, TWRP, about this in a separate article, in the category "Firmware".

Unofficial unlock method (does not work)

The official method is the above option, but if for some reason you cannot wait until the application is reviewed and approved, or you need to unlock several devices at once, you should resort to little tricks. The chance of successfully completing this operation is 50 to 50%+ Possible failures and incorrect operation of the operating system. Still want to take a risk? Then let's get started.

Go to “Settings”, go to the very bottom and click “About phone”. Now click on the MIUI version section several times. As you already understood, this is necessary in order to enable developer mode. If you already have it active, skip this point.
Now we return again to the root menu of “Settings” - “Advanced”, “For Developers”.
We see the item “Mi Unlock Status”. A new tab opens, where we click “Add an account or device.”
Next, download a utility called “Mi Unlock”, open it and unlock Bootloader with one click. If everything went well, we see in the status that the bootloader is unlocked.

Bugs and problems

Most often, problems arise from the server itself; in most cases, it is not the user's fault. But, nevertheless, you need to know how to deal with them. We offer for your acquaintance an approximate list of violations and methods for eliminating them:

The most common complaint is stop removing protection by 50%. It gets exactly halfway and freezes. Unfortunately, these are site glitches; there is nothing you can do here manually. All that remains is to try again periodically. Everything should be successful after about 2-3 times.
Doesn't comeSMSto the specified number before sending the application. The fact is that all security codes are officially sent from China and periodically expire for Russian numbers. You need to either enable a VPN with a Chinese location, or try using a different phone number.
Green button is not active. Yes, this is a common problem during the application process. This can be resolved either by simply restarting the browser or by allowing the browser to display pop-up windows. Sometimes disabling your ad blocker helps.
Can't log in to yourMi-account. This is what we talked about above, and simply inattention is to blame. Check which keyboard language is enabled, whether you entered the password correctly, and do not confuse your account ID number with your phone number.
Is a SIM card required?
No, unlocking can be done without it, it doesn’t matter.
As you can see, if you try, you can quickly and comfortably unlock the bootloader. The main thing is to follow the instructions and be very careful about the entire process. Good luck!
