Wipe data failed what to do. Wipe data factory reset: what is it and how to properly reset settings on Android
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 insignificant percentage of presence on 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 you can do without such radical measures. After all, any 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 Android System Recovery 3e mean? This is a kind of BIOS of a 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 you to simultaneously press the power and volume buttons. There are also those who must hold down the power key and both volume buttons. This only applies 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. Second option: find the desired combination by pressing all the buttons in turn. 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 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 internal memory 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 item clears the internal memory of the device, then this one 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, into which the current state of the battery, its nominal capacity and other necessary parameters are recorded. 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 the 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.
Hello everyone, Android is good, no doubt, the most popular operating system on smartphones and it has a bunch of stuff 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 in English means to clean (well, or wipe).

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 suggests 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 data. And it also says that this method is used if a 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 your smartphone will always work normally. Well, if anything happens, then it can be covered under warranty. But if you tinkered with it yourself, then there may be problems with a guarantee...
By the way, here’s another joke written on the Samsung website, in short guys, it might be that you did a reset, and then bam.. And the phone asks for a Google account, you think about it! It's just a theft protection system called Google FRP, attention, what I’m writing now is important: if you reset the data and do not delete your Google account first, the device will be blocked. When enabled, the ACCOUNT that was BEFORE THE RESET will be requested. That is, the phone will request a login and password from Google account, this is a serious turn guys!

About the subtleties of performing Wipe on Android
Many people are faced with the question of when to perform wipe? Before the firmware or after? It is better to do this before installing the firmware, since many firmwares may have a built-in automatic reboot function after installing the firmware! If the firmware contains files that are uploaded to the data section, then it’s worth checking how the system behaves; if it boots, it’s good; if not, then run wipe data.
About the subtleties of performing Wipe on Android 2
Based on personal observations, I noticed the following feature: in the popular custom firmware CyanogenMod (LinageOS) there is a script that is executed during installation from the recovery menu. This script first backups system files ( system section) before flashing and restores after. Because of this script, errors can sometimes arise and wander from firmware to the next firmware. Therefore, if you use LinageOS firmware or you know that the updater-script contains a script that performs this backup, then it is better to make a format system before updating the firmware.

The smartphone has become an indispensable part Everyday life- this is truly an extremely important device from which performance and speed are required.
Over time, the Android system begins to work a little slower, and soon it becomes simply impossible to use some applications, and even .

It is worth noting that during this procedure no user data is deleted - only the cache is cleared. Other modes in the Recovery menu can clear phone book, reset settings, and also uninstall apps, so you need to be careful.
How to make Wipe Cache Partition?
The cache reset procedure is done through a special section Android systems entitled .

FULL WIPE is a complex operation on mobile devices, which includes completely clearing user data and formatting all sections of the built-in memory. Includes a series of sequentially executed commands ( wipe dalvik-cache + format system + format cache + format/data + wipe cache partition + wipe data/factory reset + wipe battery stats). On devices running Android OS, this operation can be launched from the Recovery menu; it helps to avoid conflicts that often arise between different firmwares. Strictly speaking, Full Wipe removes all tails left over from the previous firmware.
As a result of this action, all programs, application and user data, and settings are deleted from the device.

Full Wipe for android
So, to perform Full Wipe, you need to select the following items in the Recovery menu one by one and then answer in the affirmative to the confirmation request. Navigation through the Recovery menu items is carried out using the volume down or up buttons, and selection - Power button. Let's take a closer look at each operation that is sequentially performed with Full Wipe.
1. wipe data/factory reset- deleting all settings and user data. This cleans the /cash and /data partitions located in the gadget’s built-in memory, and the .android_secure folder (storage for applications transferred to the flash drive). This operation is in many ways similar to the similar function Hard Reset, which runs on WinMo, although there are some differences. On Android Factory Reset only leads to cleaning specified sections, and the firmware itself remains untouched. At the same time, if the user, due to inexperience or intentionally, violated any functions of the system (for example, deleted some system files), a factory reset will not help restore lost capabilities - this can only be done by flashing the firmware.
On WinMo, Hard Reset not only clears all memory, but also downloads new firmware, replacing the old one, that is, it completely updates the device system to the “off-the-shelf” state.
2. wipe cache partition- clearing the cache memory (/cache section), which serves to speed up access to frequently used files. This is a kind of buffer that allows you to increase the speed of the device.
3. format/data- clearing all user data and settings. This also includes all settings of any installed or previously remote programs, if for some reason their data was not cleared immediately.
4. format/cache- clearing the cache partition.
5. format/system - complete cleaning system partition, which leads to the deletion of operating system files (erases it). Please note that once this operation is completed, the device will not be able to operate until the new firmware is installed. When cleaning the system partition, only the working partition remains factory menu Recovery.
6. wipe dalvik-cache- deleting .dex files. These files are created automatically by the system for everyone installed applications and are used in their work. It happens that these files are not compatible with new version applications - in this case, conflicts may arise. Deleting these files will lead to their new creation the next time the OS boots, which will eliminate possible problems.
7. wipe battery stats- deleting battery statistics stored in the batterystats.bin file. The operation helps recalibrate the battery. It is best to perform this operation when the battery charge is 100%. According to the application Google developers, this file serves only to display battery consumption statistics and does not affect the operating time of the device.
8. format/boot- cleaning the OS kernel.
