Fastboot Mode in Android. What kind of animal is this? Step by step instructions. What is Fastboot mode on Android - we solve the problem of constant loading in Fastboot mode

Fastboot Mode is a software component that is used to increase system boot speed, debug applications and low-level firmware. Similar functionality is found in laptops not of all models, in the main ones from Lenovo, Acer and Asus, as well as in tablets and smartphones running Android OS.

Applications differ depending on your device; if in a laptop this setting allows you to bypass the BIOS and boot much faster, then in Android this is a completely different function that allows you to access and control the system part of the smartphone. A kind of root mode to expand access rights. This is hinted at by the image itself, which contains a disassembled robot.

Fastboot Mode, what is it on Android?

We will talk specifically about the Android OS, in which this function not only helps, but also confuses some users. Fastboot Mode is designed to ensure that you get full access to the gadget when using a computer without rights restrictions. This way you can install applications, flash your smartphone/tablet, configure system settings or open root access.

Fastboot is used for developing applications for devices and is part of the Android SDK. Without this program, or at least its Fastboot element, you will not be able to fully interact with the gadget on your PC.

There are cases when this type of smartphone startup is automatically installed, so even restarting the gadget does not help. There are several reasons, but without understanding the mode, you will not gain access to the smartphone.

Fastboot Mode, what should I do?

In general, the function is very useful, because it gives more freedom in controlling the gadget through the computer, but it happens that no one called the window, but it appeared intrusively and you do not know Fastboot Mode how to get out of it. The window itself looks approximately the same in all smartphones; it contains: technical information about the smartphone and its configuration and some mode parameters.

There are several main reasons why you might end up in this menu:

You accidentally pressed the lock key and the volume key at the same time; the principle is different in some models;
System failure in the gadget.

When it says Fastboot Mode, the first thing you need to do is check to see if you can switch to normal mode and there are no problems with the system. To do this, you need to use the volume control, by pressing up you will change the active element, when you reach the inscription “Normal Boot” press the volume button down to activate the element.

This situation also happens when you turn on the mode for working with a PC, and after that it automatically goes to the Fastboot window or after picking up the gadget from the service center you forgot to disable this function. Regardless of the reason for the appearance, the standard launch is available in a similar way (except for problems with Android), in the same way you can turn off the function.

Also, so that a window with a similar mode does not appear again, you can disable the function in the settings. If you do not use these features, then it’s better to do so, you will deactivate it, but you can return it to working condition at any time, but it will not disturb Fastboot Mode on the phone. This is done this way:

Open the "Settings" menu;
Select the “Screen” section;

Uncheck the box of the same name.

This way you can block the unwanted appearance of the Fastboot window, and if such a need arises, you will return it to the active position.

Fastboot Mode - system failure

The other case is much worse, since it means there are failures in the system and does not allow the gadget to switch to normal operation mode. Alas, although this method will return the device to a serviceable position, the price for this action is very high, full formatting of the contents, in this case it is better to remove the SD memory card.

You need to go into recovery mode, this is done by holding the Power button and rocking the volume up or down, depending on the manufacturer;

Select the wipe data/factory reset item that appears, it will roll back the settings;

Click additionally wipe cache partition;

Perhaps after completing these steps you will also have to reflash your smartphone or tablet; a PC is used for this, but is not always required. Accordingly, the storage itself will be cleared and the settings will be reset to factory settings, but you can install them again.

You shouldn’t start right away from this point; perhaps you accidentally entered Fastboot mode and you just need to exit it.

After completing the steps, the problem with Fastboot Mode should be resolved and the device will return to normal operation. To avoid such difficulties in the future, simply disable fast boot mode.

Fastboot Mode is a special mode used on Android phones and is needed for debugging the mobile phone, its firmware and other interference with system files. It is also used for fast loading. In addition to Android, Fastboot is also found on other devices, but in this article we will focus specifically on smartphones from Google. We will tell you why the mode may turn on, what it is, why it is needed and what to do to get out of it. Let's get started.

What is Fastboot Mode on Android

First, let's figure out what Fastboot Mode is, and we are specifically interested in the operating system platform from Google.

Fastboot Mode is a debugging protocol that is part of the Android SDK (Android software development), which means software development for Android. This mode is used to debug the operating system itself (firmware), to update it or install additional components.

The peculiarity of this method of loading Android is that the OS itself does not start, the device only initializes the driver necessary to be able to read or write to the phone’s FS. You most often need to work with Fastboot Mode via the ADB command line, but sometimes special software is also used for this.

Here are the most common commands that are used when working with Fastboot Mode:

Flash is a firmware mode that overwrites the device’s memory, in which the Android operating system is stored.
Erase – erasing any section or the entire file system as a whole. Needed for a “clean” installation of the OS.
Reboot is a command to exit Fastboot and return the phone to the main operating system (in our case, Android).
Format – used for formatting a section, sections, or general formatting.

In order for a device switched to Fastboot Mode to be recognized by a computer or laptop, you need to install special drivers on Windows, which are released separately for a particular phone model.

What is it for?

Now you know what it is, all that remains is to explain where and why this mode is used. Access technology in “Fast Boot” is used in the following cases:

Firmware for Android phones.
Operating system update from Google.
Elimination of errors caused by failures in the OS.
Editing system files (this means firmware).
Bypass Android FRP using, for example, Fastboot Android Reset Tool.
Reading hidden information about the device, which cannot be obtained without interfering with the internal FS.

Attention: you cannot change the identification number of an Android phone (IMEI) via Fastboot. Since this parameter is hardwired into a separate chip, which cannot be accessed by conventional means.

Why does it appear

Sometimes a user encounters the fact that Fastboot mode is activated on his phone, although, according to the person, this should not happen.

Fastboot Mode on Android can be activated for the following reasons:

The user accidentally pressed the combination of buttons assigned to activate the “fast boot” mode on his gadget.
There was a glitch in the firmware, as a result of which the operating system can no longer boot normally.
A signal to start the mode was received from the computer with USB debugging enabled.

If a black screen with a debugging image appears in front of you, do not be alarmed. Usually exiting Fastboot and booting into Android is very simple. Below we will tell you how to do this.

How to exit Fastboot

There are several ways to disable fast boot mode. Let's look at each of them in more detail; for clarity, we will use step-by-step instructions, each stage of which is accompanied by a screenshot. Let's start with simpler options and only if they do not help, move on to the next method.

Reboot

The easiest way is to restart your phone. To do this, hold down the power button and hold it until the device is reset. In this case, a characteristic vibration signal will follow, after which the power key must be released.

If after rebooting the gadget again writes about enabling the “fast boot” mode, proceed to the next method of deactivating it. If your device has a removable battery, try removing it, waiting a couple of minutes, and reinserting it.

Important: enabling Recovery mode on Android is done only from the off state.

Reset to factory settings

You can also try turning on Recovery mode, which is found in any Android phone.

Options for enabling Recovery on different devices:

If your device is not in the table, you can find the necessary information online or ask a question in our Telegram group.

Through the reboot menu

So, when we get into recovery mode, we need to do the following:

The example below is shown on the basis of a Xiaomi Redmi Note 4x phone, but everything will look approximately the same in other models.

Go to Recovery.
Using the volume up and down buttons, select the option to reboot into the system. The choice is most often made by the power button.

We are waiting for reboot.

If it doesn't help, go to the next section.

Formatting internal memory

You can also try to disable Fastboot on Android by formatting its internal memory. Below we will write how this is done.

Attention! This method involves deleting all user data, including photos, videos, music, etc.

Launch Recovery mode again and select [k]Wipe All Data. We apply our choice and confirm it.

We confirm our intention.

We wait for the internal memory to finish formatting, then wait for the reboot to the main operating system. Please note that the first startup after a factory reset may take some time. Sometimes it's even 10 minutes or more. In this case, the smartphone seems to “freeze” on the power-on logo. Here you just need to wait.

Has Fastboot started again? Then read on.

Using PC

This instruction will help those who were not helped by the previous options. But it is precisely this that has the greatest effectiveness. Let's get started.

Attention: the instructions you will find below are shown using the example of Xiaomi Redmi Note 4x and are provided for informational purposes only. If you have a different model, check the procedure using information from thematic forums.

Open Yandex or Google and write a request on our phone. We find the 4PDA forum and go to it.

In order to download files here, you must register. The procedure will take only 2 – 3 minutes.

Initially, download the driver for Android Fastboot Mode.

Then we load ADB itself.

Unpack the driver into one of the folders that you need to create first.

We start the installation depending on the bitness of the operating system.

To check which Windows you have, use the Win+Pause/Break hotkey combination. In the line marked in the screenshot you will see the architecture of your Windows.

We continue installing ADB to exit Fastboot. Here we just click on [k]Next.

In an instant, the installation will be completed. Click the button marked below.

Let's move on to installing ADB.

Unpack the downloaded files into any created folder.

Launch the file marked in the screenshot.

Enter “Fastboot reboot” into the command line. Then press Enter.

Attention: at this moment the Android must be connected to the PC via USB.

As a result, a reboot will follow and your smartphone will start in normal mode.

If this option does not suit you and Fastboot on Android is still active, all that remains is to reflash the phone.

Firmware

Flashing is the last but most effective method that will help your Android get out of Fastboot. Before we continue, a reminder:

The instructions are given using the example of the Xiaomi Redmi Note 4x/5x smartphone; for other gadgets, other options and the firmware themselves are used. By installing the wrong software, you risk killing your phone.

So, let's see how the firmware of our Chinese device is installed.

The first thing you need to do is download the firmware for your Android. The best way to do this is on the popular 4PDA forum. We enter the query in the search bar and select our forum.

Fastboot Mode in Android smartphone

Those who have already dabbled with smartphone firmware undoubtedly know that Fastboot is a very useful thing. It is with its help that you can install custom (unofficial) firmware on your device. But in some cases, unexpected loading of the gadget into this mode may indicate that not everything is in order with the device. The good thing is that this problem can be easily solved. So panic attacks are completely unnecessary.

Many people think that they can get rid of this mode by simply “distorting” the device’s battery (if it is removable). But practice shows that such thoughts are fundamentally wrong. If a system failure occurs, manipulating the battery will not help return the default settings and boot the device in normal mode. Actions of a different nature will be needed here. But nothing will be difficult.

Under no circumstances should you panic, take out the battery and perform similar actions. The device also does not need repairs. This mode is a kind of smartphone BIOS. And it can be easily controlled.

Fastboot mode is a diagnostic shell for the Android system. It is somewhat reminiscent of the BIOS of a computer or laptop. But in Fastboot everything is not as clear as in BIOS. What can you do with Fastboot Mode?

Installing firmware. This option is only available if USB debugging (ADB) is enabled in the smartphone settings
Reset to factory settings. It is used if the device has started to work very poorly, but you don’t want to change the firmware
Installing recovery. Using this mode, a custom recovery is installed for subsequent installation of unofficial firmware
Working with a smartphone at the hardware level. Fastboot Mode is a very useful option for developers. It allows you to communicate directly with the hardware. Subject to the availability of appropriate software on the PC

All of the above makes it clear that Fastboot Mode is intended mainly for developers of mobile software and firmware. For the average user, this option is unnecessary. And yet, sometimes users are forced to watch this mode in all its glory.

Therefore, you need to know how you can boot your smartphone in normal mode. Or how to flash the device using Fastboot Mode. Although the latter is individual for each mobile gadget. There are no universal instructions on this matter.

How to enter the mode?

Sometimes users need to specifically enter Fastboot Mode. Perhaps the user wants to install new firmware or update the gadget using ADB. In any case, you need to know how to boot the device into Fastboot.

This procedure may differ for devices from different manufacturers. But for the most part the algorithm is the same. First you need to turn off your smartphone completely. Usually, long pressing the power button is enough to do this.

After turning off the device, you can begin loading the desired mode. To do this, you need to hold down the power and power buttons at the same time. "volume up." May be used on some models "volume down."

It is also very likely that to launch Fastboot Mode, you will have to press both volume buttons together with the power key. Here you will have to use the selection method. If successful, an image of a green robot will appear on the screen. Sometimes there may even be corresponding text.

How to exit the mode?

This question is asked by many newbies. And the answer depends on why the smartphone suddenly decided to boot into Fastboot Mode. If this happened because the user accidentally pressed the corresponding buttons, then it will be enough to simply restart the device.

But if the gadget entered this mode immediately after the reboot, then there is nothing good about it. There was probably some kind of system failure. And now the device requires user intervention in order to boot normally.

There are several options to solve the problem. They are not particularly complex, so the user does not require any special skills. You don't need specialized software either.

Method number 1. We use recovery

Recovery is a device control shell that is independent and in no way depends on the firmware version. Using this tool, you can perform a factory reset, install an update, or change the firmware.

The trouble is that for smartphones from different manufacturers, the appearance of the standard recovery can be very different. Therefore, the main thing here is to focus on the names of the items that need to be used to exit Fastboot.

If you have custom recovery installed on your device, then it’s much easier. The fact is that there are very few such things. And their interface is almost the same. However, let's consider the option with stock recovery.

So, in most smartphones, Fastboot mode does not allow you to perform any actions. The screensaver is just hanging. Each device has its own.

Now you need to enter recovery mode. To do this, simultaneously press the power button and "volume +". After a while, recovery mode will load. First you need to try to boot in normal mode. Select an item "Reboot". After this, the device should start normally.

If this does not help and the smartphone boots into Fastboot again, then you need to enter recovery mode again. Only now will the settings be reset. In the main recovery menu, select the button "Wipe Data". Then select again "Reboot".

After these steps, the smartphone should boot with factory settings. In the vast majority of cases, this procedure helps. And it doesn’t matter which company’s device is now in the user’s hands.

After "vaipa" data, everything that was installed on the device will disappear. You will have to reinstall all applications. You will also need to fully configure the device. Factory settings assume a pristine gadget. But everything will work like new.

Method number 2. We use the computer

It is rare, but it happens that the recovery mode along with a data wipe cannot boot the smartphone in normal mode. In this case, you will have to turn to your PC or laptop for help. This device will help solve the problem.

But you need to take into account that for this you will need an original USB cable from your smartphone. You will also need to download drivers for the device. Without this nothing will work. It is important to check that the drivers included in the package are those that enable ADB to work.

In some cases, when installing drivers, you will have to disable digital signature checking in the OS. If you can’t find the necessary drivers, you can rely on the system. It will try to find the required components on Microsoft servers.

Now you need to connect the device to your computer using a USB cable and wait until it is detected by the system. Next, on the command line, enter the command "fastboot reboot" and press "Enter".

After performing this action, the device will boot in normal mode with a 100% guarantee. If after entering the required command nothing happens, then the problem is in the drivers. You need to look for the “correct” ones on the manufacturer’s website or relevant forums.

If you used the above steps "wrong" driver, the consequences may be unpredictable. In particular, the user may well receive instead of a smartphone "brick". And then you will have to restore the gadget’s firmware. And this is quite difficult.

Sometimes owners of devices running Android OS are faced with the fact that their gadget goes into fastboot mode, from which it is not so easy for an untrained user to exit. Even when turning the device off and on, this mode cannot be removed, and the user again sees a screen with a notification that the smartphone is in fastboot mode. What to do in this case? Is it possible to resuscitate your smartphone or tablet yourself without going to a service center? In this article we will look at the question “fastboot mode, what is it on Android” and how to exit fastboot mode.

What is fastboot mode on Android?

Literally, this state of the device is translated as “fast boot mode”. While in this mode, the device does not turn off completely, going into sleep mode, as it were, which allows you to quickly turn it on, but not in full Android boot mode, namely in fastboot mode, designed for direct access to the device’s memory and modules, bypassing the operating system . This inclusion allows service center specialists, developers and simply advanced users to install or restore software, including the operating system itself, make backup copies, make fine system settings, etc.

Fastboot is a firmware independent of Android, located in a protected area of the gadget’s memory, which allows you to download the necessary components for debugging and restoring software using a computer, even in the event of fatal damage to Android, because program execution occurs at the machine code level, regardless of the operating system.

In what situations is Fastboot mode activated?

The Fastboot shell can be activated by the user himself when he accidentally tried to turn on his smartphone/tablet by simultaneously pressing the power and volume buttons (towards decreasing or increasing the volume). This is the most common reason for a device to unintentionally enter fastboot mode. Other common reasons:

unsuccessful obtaining root rights on the device;
unsuccessful device flashing;
Android update crashes;
deleting an important system file of the operating system if you have root rights;
the impact of viruses on system files of the operating system if you have root rights on the device.

How to exit fastboot mode

When this mode is activated, the user, when turning on or rebooting his device, sees on the screen an image of the Android symbol - a green robot and the corresponding inscription. What to do in this case and how to exit fastboot mode yourself?

First of all, you need to turn off and turn on the problematic smartphone or tablet, or better yet, remove the battery for a couple of minutes, then install it back (if it is removable) and you may be able to achieve normal loading. If not, then you can try to exit the mode in two ways: using the device itself or through a computer.

Exit Fastboot on the phone or tablet itself

We are trying to exit fastboot mode using the device itself.

Attention! With this method, all user data on the phone will be deleted and the gadget will return to its original state “as from a store,” i.e. The software environment will be in the same condition as when purchased.

I turned on the tablet, and fastboot was displayed on the screen, what is it and what should I do next?

Fastboot mode on an Android tablet or phone is used to modify the operating system - installing third-party firmware, creating backups, installing partition images and formatting them - clearing information.
All these manipulations are carried out through a computer, after connecting a smartphone or tablet via a USB cable. Drivers for the required model must be installed on the PC.
The device may reboot into fastboot mode for the following reasons:
- after unsuccessful flashing;
- as a result of a “crooked” stock recovery;
- due to a failure or error in the system.
If the screen is dark and only “fastboot mode” is visible on it, do this:
- remove the cover from the phone;
- take out the battery;
- return it to its place;
- press the “on/off” button and hold for 30-60 seconds.
If this does not help or the battery cannot be removed from the device, then you will need to reboot the device through the computer and the command line. First you need to install drivers on your PC. For most devices the process is similar:
- we find the necessary “firewood” on the Internet, easy to find through Yandex;
- download, click on the archive and extract the contents into a folder;
- then, connect one end of the USB cable to the computer, the other to the smartphone;
- the device should be detected, and a message will appear asking you to install the driver;
- select “install from a specified location” and click “next”;
Now let's get started working with the device:
It happens that after an incorrectly installed recovery, the device boots into fastboot mode. In this case, I’ll tell you how to exit fastboot mode on Android further.
In addition to the above, you will need ADB - a program for working with phones and recovery, which was originally available - it is better to look for it on foreign forums. The sequence of actions is as follows:
- download ADB on PC;
- unpack the contents of the archive into a folder;
- We also transfer the downloaded recovery there, which should be called “recovery.img”;
- in this folder run the cmd.exe file;
- The command line will appear;
- into it we enter “fastboot erase recovery” and “fastboot flash recovery recovery.img” after each press “enter” - with these commands we updated the recovery;
- Next we write “fastboot reboot” and press “enter”.
After this, the device should work.
If loading into fastboot mode happened accidentally, then most often there will be a menu on the phone screen. You can move around it using the volume rocker. After selecting “normal boot”, press the power button.
When there is no menu on the screen and you cannot use the computer, you can try to boot the system through recovery:
- remove the battery to turn off the device and put it in place;
- simultaneously press the power and volume down buttons;
- hold until the menu appears;
- use the volume rocker to go to the “reboot system now” item;
- press the power button.
These options do not guarantee fastboot exit on all phones.
