Smartphone owners often use them to store personal information. It could be business correspondence, electronic invoices, Contact Information, photographs, etc.

Reset by wipe (wipe data/ factory reset) - good idea, but in some cases this function may not be enough. For example, when employees of the famous company Avast bought 20 used Android smartphones, then they were able to recover photos, Google search history, emails, text messages and contact information.

There is a method that will help the user completely erase all information and avoid troubles associated with leakage of personal files.

Preparing for a factory reset

Those who are interested in what wipe is on Android should first of all install the FRP (Factory Reset Protection) application. Google developed FRP as an additional layer of security for Android 5.0 Lollipop. If the gadget is stolen, the program will not allow thieves to erase all files on it for the purpose of further sale to third parties.

If you perform a wipe data/factory reset with the FRP application enabled and try to set up the device again, the program will require you to enter the username and password for the last Google account registered on the device. If a person does not have such data, then the smartphone will remain locked. Attackers are unlikely to be able to sell a mobile device that doesn’t even run the operating system.

After installing FRP, you need to perform the following steps:

On smartphones and tablets Android based there is a special menu Recovery Mode or simply . This special mode loading the device, thanks to which you can reset all settings or, say, install new firmware on the device.

This is what Recovery Mode looks like on a Samsung smartphone:

To bring up this menu, you need to do a number of steps along with rebooting the smartphone. For example, on Samsung Galaxy S3 process is as follows:

  • Turn off your smartphone.
  • Press the volume up button, Home button and the power key of the smartphone at the same time.
  • Release the buttons as soon as you see the recovery menu logo.

Please note that the image shown above is stock recovery Mode. There are also custom versions of the menu, they are installed by the user independently and can have a completely different look.

There are several items in the recovery menu that raise questions among users. Let's talk about some of them.

Wipe data/factory reset

Using Wipe data/factory reset deletes all applications and data (cache, Accounts), excluding data such as music, photos, videos. It is usually used if any errors occur when using the device, or the smartphone or tablet starts to slow down due to some application, or the user wants to return the device to original condition and reset settings.

Wipe cache partition

Wipe cache partition is a way to clear a cache partition. This area stores temporary files, which remained after running applications or updates. It is used if the smartphone works slowly or starts to slow down. In this case, applications are not deleted, unlike the previous case.

Other types of recovery menu

Some recovery menus have additional items. For example, in Recovery Mode on Xiaomi devices can choose additional modes cleaning, like, say, Wipe SD Card - deleting data from a memory card. And the menu look is completely different.

Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on operating system"Android". This OS was developed by Google, and now its market share is incredibly high. iOS from Apple and Windows Phone an insignificant percentage of presence in mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system crashes - distinguishing feature any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that it is possible to do without such radical measures. After all, every Android gadget has Android. System Recovery 3e. How to use it and what is it even? This is what we will talk about.

What kind of animal is this?

What does it mean Android System Recovery 3e? This is a kind of BIOS mobile device. Any operating system has its own BIOS - basic system I/O that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It serves to restore the functionality of a smartphone or tablet, apply critical updates or do a factory reset. 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 language. Therefore, many people do not even know how to use recovery correctly.

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

How to enter recovery?

It depends on the specific model devices. 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. Old models with mechanical button"Home" requires pressing this button as well. Some devices require pressing simultaneously power and volume buttons. There are also those who must 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 “crooked” translation. Standard Methods Logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the key combination you are looking for. But this option is not suitable for everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. The second option: find the desired combination by pressing all the buttons one by one. Now let's move on to the Android System Recovery 3e menu items.

Reboot system now

This menu item does full reboot devices. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this 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 a reboot: to allow the device to 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 located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this you need to go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.

This paragraph has other subparagraphs 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, it 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 for them. If there are errors, then put this firmware no need. That's the whole story.

Wipe Data. Factory Reset

This is a very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system 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, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in 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 the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly states that it is imperative to use the Wipe Data & Factory Reset item before each firmware update of the device.

Wipe Cache Partition

Another one useful command in Android System Recovery 3e. The recovery instructions say that you need to use this option in tandem with Wipe Data. If the previous paragraph clears internal memory device, then this clears its cache. Namely, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache 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 clearing the Android OS cache. 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 have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.

Wipe Battery Stats

This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, in which the Current state battery, its nominal capacity and other required parameters. Resetting usage statistics battery, it will be possible to extend her life a little. Yes and new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory smartphone. This item allows you to clear a memory card or built-in memory, format it, or attach it as a drive directly from 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 your smartphone into the operating system. In order to mount the device’s memory card as a drive, you need to select Mount USB Storage. Once the connection is established, the computer itself will establish necessary drivers for work.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy necessary files and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.

Recovery errors

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

So, if the error occurs due to broken file firmware, you should download it, connect your smartphone to your computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. And here Android error System Recovery 3e "No command" is very rare. It only appears when the user tries to install an update via ADB. Usually this method doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.

Conclusion

So, let's summarize. We tried to describe Android capabilities System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.

Wipe (wipe – wipe, wipe) in Android system 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 preinstalled programs, and will help get rid of the following problems:

  • Possible malfunction as a result getting root rights;
  • Incorrect functioning and occurrence of system errors;
  • Deterioration in performance as a result of operating system updates;
  • Problems due to flashing, i.e., after switching from original to custom firmware;
  • Deleting all personal data (hard reset) when pre-sale preparation devices.

Types of “reset” on Android

Hard reset on Android can be 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 sections.
  2. Partial – deletes specific folder(directory).

Ways to perform wipe

Execute Android wipe possible from the following modes:

  1. Settings menu: go to the settings menu, then “recovery” and “reset”, check the “clear SD card” checkbox (data stored on the memory card, programs and files inclusive are deleted, information from the phone’s memory will also be deleted).
  2. Using the “reset” button located on the device (if provided by the manufacturer): using a paperclip (or similar object), press and hold the reset button for 15-30 seconds (the settings are reset to factory settings).
  3. Recovery menu: to get to 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 other key combinations. We move through any menu by decreasing or increasing the volume, and selecting actions by pressing the “power” (turn on) key. In addition, it is possible to use a PC and ADB programs, universal for all devices. First enable USB debugging.

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

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

  • Partial Wipe (in case of a “glitch” of some program), with 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). The content is saved.

Wipe through recovery

Now directly about wipe through recovery. In classic recovery option There are two types of reset available for Android:

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 the root directories and personal settings, but we save media files (image, video, music).

Wipe cache – we erase temporary information about the operation of programs and applications. This action is required if a system malfunction occurs.

What if nothing helps? You shouldn’t blame the fact that “your hands don’t grow from there”, you just need to perform “WIPE DATA/FACTORY RESET”. In this case, it is possible to do wipe applied to any section of the system.

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

Additional information about wipe on Android

Often, on sites that publish information about Android, you can find instructions on how to flash the firmware, as well as how to obtain root rights. These guides instruct you to perform a factory reset 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 recovery menu and talks about ignorance file structure Android systems. The wipe data/factory reset action deletes the data partition containing 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 there.

Some nuances of performing a wipe on Android

Often users are faced with a dilemma: when to reset the settings, 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 with which it performs automatic reboot

system after installation has been completed. If in the firmware in the section " data wipe"There are uploaded files" wipe data».

", let's see how the system will perform its functions after loading, if it's bad, then perform "

And a little more information about the subtleties. Many experts agree that the emphasis of custom CYanogenMod firmware

You can call it a script - part of the installation from the recovery menu, which initially backs up the system files, and after flashing it restores them. As a result, errors may occur. Therefore, if you decide to use this firmware, then first run format system.

That’s basically all we wanted to tell you, we really hope that our information turned out to be useful. Recovery Mode or simply the recovery menu is a special smartphone mode that allows, for example, to reset certain data, reflash touch device

, run various tests, etc. Many users do not know about this menu. Don't be surprised, because the developers hid it away - one wrong click can lead to the loss of all data. However, in reality, the recovery menu can be extremely useful if you know where and what to click. In this article we will talk about one of the menu items - Wipe data/Factory reset. Let's start with the translation: Wipe data is translated into Russian as “wipe data”, and Factory reset is “reset to factory settings”. So, we can conclude that this item

The Wipe data/Factory reset item replaces resetting settings using the menu of your Android smartphone: if for some reason you cannot use the main menu, use recovery.

How to open recovery? Usually you need to press and hold the Volume Up and Power keys when the smartphone is turned off. For example, as in the case of Xiaomi:

Sometimes you need to press the Volume Down and Power keys. On Samsung smartphones another scheme can be used: volume up key, Power + Home when the smartphone is turned off (press and hold until the device wakes up).

If everything is done correctly, you will see this picture:

Then this:

And only then the recovery menu will load. Here, as you can see, there is Wipe data/Factory reset.

If you select it, a confirmation will appear whether to continue deleting data or not. Selecting Yes will continue to clean the device.

Before selecting this menu item, think carefully about whether you have saved all the data - otherwise it will be deleted. And remember that if you don't delete Google account from the device before resetting the data, then the next time you turn it on you will have to enter the password for this account (on modern Android versions). If you know him, there will be no problems. If not, this is a serious problem, believe me.
