• What is factory reset. Wipe data factory reset: what is it and how to reset it correctly on Android

    Hello everyone Android is good, no doubt, the most popular operating system on smartphones and it has a lot of things that we don’t know yet ... Today we’ll talk about what wipe data / factory reset is. But first, let's translate this into Russian. So, according to the words, wipe is from English means to clean (well, or wipe). The word data is data, factory reset means reset to factory settings.

    The wipe data / factory reset thing itself is an item in the Recovery menu, which is a special boot mode for an Android smartphone. In this mode, you can perform a data reset, flash your smartphone, you can get root rights. The wipe data / factory reset item is responsible for deleting data from the DATA and CACHE sections, all your programs and their data are also deleted, personal settings are also deleted. However, all your pictures, vidos, music remain, all this remains.

    On one good site (androidp1.ru) I found a lot of information about Android, and something interested me there, in general, guys, this is what a person writes, read carefully, it seems important:


    Well, here is the menu item itself:


    It turns out that the full name of the menu is Android system recovery, the name itself already indicates that this is a recovery menu

    Even on the official Samsung website it is also written that the wipe data / factory reset item is responsible for resetting the data. And it is also written there that this method is used if the smartphone or tablet does not want to turn on. By the way, guys, if you don’t know something, then don’t touch it, follow this rule and the smartphone will always work normally. Well, if anything, then you can incur a guarantee. But if you poked around in it yourself, then with a guarantee there may be troubles ...

    By the way, here's what a joke is also written on the Samsung website, in short, guys, it may be that you did a reset, and then bam .. And the phone asks for a Google account, you think in business! It's just a theft protection system, it's called Google FRP, attention, what I'll write now is important: if you do a data reset and don't delete your Google account before that, the device will be blocked. When enabled, the ACCOUNT that was BEFORE the RESET will be requested. That is, the phone will ask for a username and password from a Google account, this is such a serious turn guys!

    Mobile devices have already become a part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are very popular. This OS was developed by Google, and now its market share is incredibly high. Apple's iOS and Windows Phone have negligible presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to "fail". Various system failures are a hallmark of any operating system. No matter how advanced she is. Very often devices have to be reflashed. But not everyone knows that you can do without such drastic measures. Indeed, in any gadget on "Android" there is Android System Recovery 3e. How to use it and what is it all about? We will talk about this.

    What is this animal?

    What does Android System Recovery 3e mean? This is a kind of BIOS of a mobile device. Any operating system has its own BIOS - a basic input-output system that can work even if the main OS is damaged. Sometimes the BIOS is different from the standard one (as, for example, in Android devices). It serves to restore the functionality of a smartphone or tablet, apply critical updates, or reset to factory settings. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English. Therefore, many do not even know how to properly use the recovery.

    That is why this article was written. Android System Recovery, the instruction for which is absolutely necessary, is a powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to spend money on masters. Doing everything yourself is much easier and cheaper. We will analyze each item of the recovery menu and tell you everything we can about it. So let's start.

    How to enter the recovery?

    It depends on the specific device model. In some devices, you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Older models with a mechanical home button require you to press that button as well. Some devices require the simultaneous pressing of the power and "Volume" buttons. There are those who need to hold down the power key and both volume buttons. This applies only to original devices from well-known manufacturers.

    But there are also frankly "Chinese" gadgets with an incomprehensible operating system and a "crooked" translation. The standard methods for entering the recovery in these cases may not work. There are several options here. First: study the documentation of the smartphone (if any) and find the key combination you are looking for. But this option is not for everyone. Most of these devices either do not have any documents at all, or there is no Russian language in the documents at all. The second option: find the desired combination by pressing all the buttons in turn. And now let's move on to the Android System Recovery 3e menu items.

    Reboot system now

    This menu item performs a full reboot of the device. After selecting this option, the smartphone will load the standard operating system "Android" without any changes. Usually this item is used upon completion of all manipulations in the recovery. Or in the event that you booted into this mode by accident. Although how this can be done by chance is unknown. Be that as it may, Android System Recovery 3e, whose instruction manual is simply vital for the user, has such an item. And this has to be taken into account.

    The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of the reboot: let the device apply all the changes made. True, after some of them, the smartphone may not boot at all. But that's a completely different story.

    Apply Update from External Storage

    This menu item allows you to apply the update that is on the memory card. By the way, new firmware is also installed through this item if the main OS is not loaded. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this, go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If it's just an update file, then you should select Apply Update From SD Card. This is how any device is flashed with the help of recovery. Simply copy the firmware file to the root of the memory card, go into the recovery and select the desired item.

    There are other sub-clauses in this paragraph that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required. If there are errors, then you do not need to install this firmware. That's the whole story.

    Wipe data. factory reset

    Here is a very important point. This option is able to restore the device without any firmware. This tool resets the operating system of the gadget to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, whose instruction manual is discussed here, was created just to revive the device without serious interference with the firmware. And this option allows you to perform this operation.

    This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, then the firmware may not be installed at all, and then the user will receive a completely "dead" smartphone. There is no instruction in Russian, but the one that is, clearly says that it is necessary to use the Wipe Data & Factory Reset item before each device firmware.

    Wipe Cache Partition

    Another useful command in Android System Recovery 3e. The instruction for the recovery says that you need to use this option in tandem with Wipe Data. If the previous item clears the internal memory of the device, then this one clears its cache. Namely, the working files of applications are stored there. Of course, if this is not done before the firmware, then nothing bad will happen. It's just that in the future, when installing new programs, the cache of the device will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for cleaning the cache of the Android OS. And they work great.

    It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even "cleaner", which will positively affect the performance of the operating system. The instruction in Russian for Android System Recovery 3e recommends performing this procedure after the reset. Until the device is rebooted. Then everything will be as it should be.

    Wipe Battery Stats

    This feature helps to refresh the battery of the device. After clicking on this item, the battery cache begins to be cleared, in which the current state of the battery, its nominal capacity and other necessary parameters are recorded. By resetting the battery usage statistics, it will be possible to slightly extend its life. Yes, and the new firmware will work more adequately with the battery. For some reason, many "gurus" of "Android" dismissively refer to this option. But it's actually very helpful. However, it is not recommended to use it too often. Just before flashing the device.

    Mounts. Storage

    Here are the controls for the internal and external memory of the smartphone. This item allows you to clear the memory card or built-in memory, format it or attach it as a drive directly from the recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot the smartphone into the operating system. In order to mount the device's memory card as a drive, select the Mount USB Storage item. As soon as the connection is established, the computer itself will install the necessary drivers for operation.

    After the connection is established, you can do anything with the memory card: format, clear, copy the necessary files, and so on. In order to unmount the USB flash drive, you should select the Umount USB Storage item on the smartphone screen in the recovery. After that, it will be possible to move on to other recovery points and perform further resuscitation of the device on its own.

    Recovery errors

    Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of a firmware or package. It can occur for several reasons: the file with the firmware is damaged, incorrect information in the binary file, or the firmware simply does not fit this device. But there is another option: a factory reset was not performed before the firmware. It's good that they can be easily fixed in the same recovery. There are several ways to do this.

    So, if an error occurs due to a broken firmware file, then you should download it, connect your smartphone to your computer, go to the Mount & Storage menu item and select Mount USB Storage. After that, you can re-copy the firmware to the root of the memory card. If you forgot to make a "wipe", then there is nothing easier than moving up a few levels and selecting the appropriate menu item. But the Android System Recovery 3e "No command" error is very rare. It only appears when the user tries to install an ADB update. Usually this method does not work. As a result, this error appears. So it doesn't make sense to use this method. Still nothing will work.

    Conclusion

    So, let's sum up. We have tried to describe the features of Android System Recovery 3e. The instruction that resulted from this attempt will help novice users of the Android operating system learn how to restore the health of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and good money savings.

    Many sources claim that before installing custom ROM, for example, , you need to do wipe system, although there is also an opposite opinion. How to be in this situation? There is only one answer: the first option is correct. Why is that? Let's try to figure it out.

    wipe aims to clear sections of the memory of your device. Carrying out the operation leads to both the loss of personal data and the loss of downloaded applications. System applications acquire the initial state. It turns out that wipe returns your device to the state in which you bought it.

    Here are a few different wipes and a short description of them:

    Wipe data/Factory reset: in this case, all your personal data will be deleted and the system will return to its original form.

    Wipe Cache Partition: This action will clear the cache. With this method, no personal data is lost.

    Wipe Dalvik Cache: all your programs are in the directory tree of the Dalvik cache, wipe affects it, while personal data remains intact.

    Which wipe in which case to apply? What is its meaning?

    If you are installing a new ROM without committing wipe, then there is a lot of "garbage" from the old system, which leads to the unstable operation of the new one. You get a bunch of errors, crashes and other problems. For this reason wipe always needed.

    Let's now consider which wipe to use in which case.

    When you install a new custom ROM, but before that they used stock firmware, it is worth using the first option - " Wipe data". It is also necessary when moving from one version to another, for example, from to .

    When it comes to small updates, for example, you are moving from Cyanogon Mod 9.0 To Cyanogen Mod 9.1 or install, then you need to apply " Wipe Cache Partition" And " Wipe Dalvik Cache".

    That, in fact, is all. Now you know what wipe helps to solve many problems associated with custom roms. If after installation a bunch of errors occur in the system, you can easily fix them. If wipe does not help, then you need to use the "" option in recovery mode. We hope that now questions on the topic do wipe or not, you will not have.

    Wipe (wipe - wipe, wipe) in the Android system is called a factory reset. This process is also called "formatting" or "Hard Reset". Why do you need to reboot on android?

    The fact is that after this action, the device will be completely cleared of pre-installed programs, and will help get rid of the following problems:

    • Possible failure of work as a result of obtaining root rights;
    • Incorrect functioning and the appearance of system errors;
    • Performance degradation as a result of operating system updates;
    • Malfunctions due to flashing, i.e., after switching from the original to the custom firmware;
    • Deleting all personal data (hard reset) during the pre-sale preparation of the device.

    Types of "reset" on Android

    Hard reset on android can be conditionally divided into two types:

    1. Full (aka hard reboot on android) - deleting all programs and data on the device itself, or in any of the selected partitions.
    2. Partial - deletes a specific folder (directory).

    Ways to perform wipe

    You can run Android wipe from the following modes:

    1. Settings menu: go to the settings menu, then “restore” and “reset”, check the box “clear SD card” (the data stored on the memory card, programs and files inclusive are deleted, information will also be deleted from the phone’s memory).
    2. Using the “reset” button located on the device (if provided by the manufacturer): using a paper clip (or similar object), hold down the reset button for 15-30 seconds (the settings are reset to factory settings).
    3. Recovery menu: to get into the recovery menu, turn off the power, hold down the home key and the volume rocker to increase, simultaneously with the power button. Important: Different devices may have different key combinations. We move through any menu by decreasing or increasing the volume, and we select actions by pressing the “power” (turn on) key. In addition, it is possible to use a PC and the ADB program, which is universal for all devices. Turn on USB debugging first.

    a) In the standard Android recovery menu: select Wipe data / factory reset, then “Wipe cache partition”, reboot the smartphone (Reboot system now);

    b) In the Recovery CWM menu (or similar):

    • Partial Wipe (in case of a “glitch” of some program), saving all data or programs: “Wipe cache partition”, then “Advanced”, then “Wipe Dalvick Cache”, finally reboot, or reboot on android
    • Full Wipe or hard reset android (removing all programs and their data): select "Wipe data / factory reset", then "Wipe cache partition", and reboot the smartphone (Reboot system now). Content is saved.

    Wipe through recovery

    Now directly about wipe through the recovery. In the classic version of Android recovery, two types of reset are available:

    To delete all data stored in the DATA or CACHE sections and folders containing program data. In this way, we permanently remove all applications along with root directories and personal settings, but we keep media files (image, video, music).

    Wipe cache - we erase temporary information about the operation of programs and applications. This action is required in the event of system failures.

    What if nothing helps? You should not blame the fact that "hands do not grow from there", you just need to perform "WIPE DATA / FACTORY RESET". In this case, it is possible to wipe applied to any section of the system.

    And the last, fourth mode from which you can perform a wipe is the Bootloader menu, but in this case you need to use fastboot tools.

    Additional information about wipe on Android

    Often on sites that publish information about android, you can find instructions for firmware, as well as obtaining root rights. These guides instruct you to perform a factory reset in this way: wipe data, wipe cache, wipe dalvik cache, format data. However, this is a frankly incorrect recommendation, because it does not reveal the full structure of the recovery menu and speaks of ignorance of the file structure of the Android system. The wipe data/factory reset action removes the data partition that holds the dalvik cache directory. This means that some manipulations will be completely unnecessary. The fact is that wipe and format are terms that have the same meaning, for example, the system / xbin partition does not contain format files, but the wipe file is located there.

    Some nuances of performing a wipe on Android

    Often users are faced with a dilemma: when is the reset done, before flashing the device, or after? The answer lies on the surface - of course before flashing, because any firmware usually has a built-in function that automatically reboots the system after the installation has been completed.

    If in the firmware in the section " data» there are uploaded files « wipe”, we look at how the system will perform its functions after loading, if it’s bad, then we execute“ wipe data».

    And a little more information about the subtleties.

    Many experts agree that the script can be called the focus of CYanogenMod custom firmware - part of the installation from the recovery menu, which initially backups the system files, and after flashing, restores them. As a result, errors may occur. Therefore, if you decide to use this firmware, then first execute format system.

    That, in fact, is all that we wanted to tell, we really hope that our information was useful.

    In this article, we will look at how to properly perform a factory reset or wipe on Android. What types of reset are there and other various nuances.

    Reset settings, Hard reset, Wipe - these are all synonymous words (one and the same) that mean partial or complete reset of all data and settings.

    Why do you need to perform a factory reset?

    A factory reset cleans Android of your data and programs and may be needed for various reasons:

    • If Android does not work correctly and critical errors often occur
    • After Rooting Android
    • After the firmware (switching from the original firmware to custom, OS update)
    • In order not to distribute personal data (when reselling the device and transferring it to other hands)

    In the Android ecosystem reset commonly called - wipe. The English word Wipe [wipe] - wipe, wipe. For many, a familiar word in this case would be formatting or format. So remember, Wipe in Android is a factory reset, formatting!

    Performing a factory reset using the hardware reset button

    To reset, take a thin paper clip and straighten it. Press the reset button with a paper clip for 15-30 seconds. After that, the Android settings are reset.

    Wipe on Android from the Recovery menu

    Wipe can be performed both from standard Recovery and custom. Performing Wipe from the Recovery menu is more flexible than from the settings menu.

    Performing Wipe from Standard Recovery

    In standard Recovery, you can perform 2 types of factory reset.

    • wipe data/factory reset- will delete data from the DATA and CACHE partition and a folder in the internal memory with program data. With this wipe delete all your programs and their data, Personal settings,.

    If the problems persist, then it's worth doing WIPE DATA / FACTORY RESET!

    Also in custom recovery there is an add. reset options, for this you should go to the MOUNTS AND STORAGE menu. Here you have the option to wipe any Android partition.

    From the Bootloader menu through the Fastboot utility

    It is also possible to execute wipe through the Bootloader menu, using the fastboot utility for flashing Android devices. It looks like this:

    fastboot erase cache

    About the subtleties of performing Wipe on Android

    Many are faced with the question of when to perform wipe? Before firmware or after? It is better to perform it before the firmware, as in many firmwares the function of automatic reboot after installing the firmware can be built in! If the firmware contains files that are uploaded to the data section, then it is worth checking how the system behaves if it boots up, well, if not, then execute wipe data.

    About the subtleties of performing Wipe on Android 2

    According to personal observations, I noticed the following feature, in the popular custom firmware CyanogenMod (LinageOS) there is a script that is executed during installation from under the recovery menu. This script first backups the system files (system partition) before the firmware and restores after. Because of this script, errors can sometimes occur and roam, from firmware to the next firmware. Therefore, if you use LinageOS firmware or you know that updater-script has a script that performs this backup, then it is better to make a format system before flashing it.

    That's all, stay with the site!
