What is Wipe Cache Partition on Android and why is it needed. What is factory reset


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 before installed programs, and will help get rid of the following problems:

  • Possible malfunction as a result of gaining 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) during pre-sale preparation of the device.

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 point is that wipe and format are terms that have the same meaning, for example system section/xbin does not contain format files, but there is a wipe file 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 that automatically reboots the system after the installation has been completed.

If in the firmware in the section " data"there are uploaded files" wipe", let's see how the system will perform its functions after loading, if it's bad, then perform " wipe data».

And a little more information about the subtleties.

Many experts agree that the highlight of the CYanogenMod custom firmware can be called a script - part of the installation from the recovery menu, which initially backs up the system files, and after flashing, 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.

A friend advises me to reset the settings using Wipe data / factory reset, but I can’t figure out what it is and how to do it. Please tell me.

    Wipe data factory reset is a function that is used to remove applications and user data from the device memory. It is used when unstable work smartphone, before installing new firmware or selling it, when you need to clean it. Please note that the system folder and other system partitions except data and cache remain untouched after wipe data factory reset.

    Translated into Russian, Wipe data factory reset is roughly equivalent to “data wipe and factory reset,” but most often they just say reset to factory settings.

    Now I’ll tell you how to do a wipe data factory reset. There are two options for this - through the device settings or recovery. The first method is easier, so I'll start with it:

    • find the application with the gear icon and go into it - these are general settings;

    • Scroll down, open the “backup and recovery” section;
    • go to the “reset to factory settings” item;
    • At the bottom, click the “reset device” button;
    • then tap on “clear all”;
    • a window will appear warning you about permanent deletion information, we give consent.

    The tablet or phone will turn off, a green robot will appear, under which the cleaning process will be shown. The android device will then start to boot, but it will take longer than usual - this is normal.

    Through recovery, resetting to factory settings is done as follows:

    • turn off the device completely;
    • press and hold the combination of the power and volume buttons up or down, the combination depends on the smartphone model;
    • wait until the manufacturer's sign appears;
    • release the buttons.
    • if CWM or native is installed, then use the volume control rocker to move to the “wipe data factory reset” section;
    • open it with the “on/off” button;
    • go to the item “yes - wipe data factory reset”;
    • press the power button.

    If after the end of the process you need to turn on the Android phone, then go back through the “go back” item, and then select “reboot system now”.

    In TWRP the process is similar, the only difference is in the interface:

    • go into recovery as described above;
    • tap on the “wipe” item;

    • A section will open, at the bottom we move the blue circle to the right (maybe a square).


    To boot into the system, click the curved arrow in the lower left corner, then the “reboot” and “system” buttons.

    Before flashing the device, three steps must be performed - Wipe dalvik cache, wipe data factory reset, wipe cache partition. Translation into Russian “wipe cache partition” is cleaning the cache partition.

    This memory area stores temporary files that remain after running applications or system updates, so this procedure can be done when the smartphone is slow or freezes.

    When installing custom firmware, for example, CyanogenMod or MIUI, updating to latest version through recovery, to avoid conflicts between the remaining and new files, you must run Wipe cache partition. Wipe cache partition what it is is now clear, I’ll write later how to do it.

    This procedure with the phone is carried out only through recovery. On CWM for this you need:

    • open the general recovery menu by holding down the button combination;
    • Use the volume control keys to go to the “wipe cache partition” section and press the power button;
    • in the same way, move to the “yes - wipe cache” item and select it.

    If TWRP is installed, then do this:

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 firmware. Strictly speaking, Full Wipe removes all tails remaining from the previous firmware.
As a result of this action, all programs, application and user data, and settings are deleted from the device. In fact, it even erases itself operating system, therefore, without having a file with the image of the new firmware, it is strictly not recommended to run this operation. It is better to perform a full backup before Full Wipe working system in case new firmware will not want to function normally. When erasing the operating system, only the external flash drive remains unaffected, with the exception of the system folder.android_secure, in which Android stores applications moved to the memory card.

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 Hard Reset function that is performed on WinMo, although there are some differences. On Android, Factory Reset only leads to clearing 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.

Smartphone for modern man is a necessity. This device is used for entertainment, work and communication with friends. And almost every day, due to one need or another, users install applications of varying degrees of usefulness.

It is not surprising that over time the system begins to respond less quickly to incoming commands and some of them have to be uninstalled. This partially helps, but in the depths of the operating system there still remains some data regarding the operation of previously installed applications, which will negatively affect the operation of the device. To remove them, you need to clear the application cache or Wipe Cache Partition. What it is, as well as some features of performing this action will be discussed further.

If you are quickly running out of memory and don't know about , you are advised to familiarize yourself with the application.

General description of the problem

As mentioned above, each application during its operation uses some temporary files, which are stored in a special section of the system called the cache. It's interesting to note that these files may remain there even after the application itself has been uninstalled. For technically savvy users, this problem is obvious and they regularly clean up temporary files, however, most people do not do this, which sooner or later leads to problems.

How to understand that cleaning is needed

In order to understand whether cleaning temporary files is required, you should pay attention to the operation of applications and the smartphone operating system as a whole. If, with a moderate number of installed applications and their correct use, the device slows down, then there is a clear need to carry out work using Wipe Cache Partition. Naturally, this can happen for other reasons, but wiping the system cache is the first thing to do.

Features of the mode

What is Wipe Cache Partition? It is important to note one of the most significant features the Wipe Cache Partition cache cleaning mode in question. There is no reset when the task is completed custom settings, deleting applications or contacts phone book, unlike other wipe modes, which are also present among the possibilities.


System recovery and how to clear the application cache

For a more complete understanding of the issue, it is worth considering such a section of the system as Recovery. Speaking in simple words, this is the second bottom of the system, which allows you to complete a series basic actions with her. Most often, recovery is used to change the device firmware, Reserve copy or system recovery and similar actions. The application cache is also cleared through recovery.

In order to enter the recovery menu, you must simultaneously hold down several buttons on your smartphone. Most often, this is by simultaneously pressing both volume change keys and the device power off key. So, the algorithm of actions should be as follows:

  1. Turn off your smartphone.
  2. Simultaneously hold down the volume rocker (both keys) and the power button. Hold until the characteristic splash screen appears.
  3. In the recovery menu that appears, find the Wipe Cache Partition item and activate it. (Switching usually occurs using the same volume rocker, and selection with the power button).
  4. After clicking on the menu item, the display will show the actions being performed and upon completion will confirm the success of the work.
  5. Next you need to choose to restart or turn off the device.

After the device is rebooted, it will be cleared of traces of applications. This applies to both installed programs and those already uninstalled. As a result of the Wipe Cache Partition procedure, the operating system and applications will run faster. The procedure should be repeated periodically, especially if you have to frequently install and uninstall applications. In any case, preventing a problem is better than fighting it.

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

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

Why do you need to perform a factory reset?

Factory reset performs Android cleaning from your data and programs and may be needed for various reasons:

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

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

    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 the system files (system partition) before flashing the firmware and restores it 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.
