What does Wipe data factory reset do? What is Wipe Cache Partition on Android and why is it needed?


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, 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 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 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 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. By resetting the battery usage statistics, you can slightly extend its life. And the 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.

Wipe (Wipe) for Android. How to properly reset settings on Android. In this article we will look at how to properly reset or wipe settings on Android. What types of reset are there and various 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 obtaining 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, resetting settings is usually called wipe. The English word Wipe [wipe] - wipe, wipe. For many, a familiar word in in this case there will be formatting or formatting. So remember, Wipe in Android is a reset, formatting!

Types of wipe on Android

Wipe on Android can be divided into full and partial.

Full wipe - completely deletes all data on the partition.

Partial wipe - deletes a specific directory (folder) on a partition.

Which modes can you use to Wipe on Android?

  • From Recovery menu
  • From the Bootloader menu using fastboot
  • Using the hardware reset button (if available)

    • How to do wipe on Android

    Performing a factory reset from the settings menu

    Go to the settings menu and find the menu Recovery and Reset and go to it

    In the menu you can (if necessary) mark Clear SD card- this will erase the data on the memory card and internal memory too, as well as all programs and their data!

    Performing a factory reset using the hardware reset button

    To reset, take a thin paperclip and straighten it. Clamp with a paper clip reset button 15-30 seconds. After which the Android settings will be reset.

    Wipe on Android from the Recovery menu

    Wipe can be performed from both standard Recovery and custom one. Executing Wipe from the Recovery menu is more flexible in its capabilities than from the settings menu.

    Executing 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 the folder in the internal memory with program data. With this wipe all your programs and data will be deleted, Personal settings, .

    Wipe cache

    Executing Wipe from custom Recovery

    Custom Recovery also has similar items as the standard one.

    wipe data/factory reset - will delete data from the DATA and CACHE partition and the folder in the internal memory with program data. This wipe will delete all your programs their data, Personal settings, but all your pictures, videos and music remain.

    Wipe cache- temporary program activity data is deleted, this reset needed if you sometimes have errors on Android!

    If you have any problems with the operation of programs, then you should try to do it first WIPE DALVIK CACHE, you can do it from the advanced menu, all your programs and their data will remain

    If the problems persist, then you should do a WIPE DATA/FACTORY RESET

    Also in custom recovery there is an additional feature. reset options, to do this, go to the MOUNTS AND STORAGE menu. Here you have the opportunity to wipe any partition of Android.

    From the Bootloader menu via the Fastboot utility

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

    fastboot erase cache

    More information about wipe on Android

    This information is for those who want to know more about wipe.

    nonsense about WIPE

    On the Internet, in particular sites on Android topics, you can find instructions on how to install firmware or obtain root rights. In these instructions they often write that you need to do a wipe and describe how to do it. It sounds something like this:

    After flashing the firmware, do - wipe data, wipe cache, wipe dalvik cache, format data!

    THIS IS COMPLETE BULLSHIT AND Nonsense!

    Why? All because people don’t read the logs that Recovery produces and don’t know the file Android structures, plus lack of knowledge of Linux commands.

    When you perform wipe data/factory reset, the data section is erased, and in the data section there is a dalvik cache directory, and the cache section is also erased. Now you understand why you don’t need to do all these unnecessary manipulations! But you probably noticed that I didn’t say a word about format?

    FORMAT or WIPE

    WIPE and format are one and the same! How so? some Android literati might say! But like this, doing wipe or format is the same thing and it’s easy to check. In the /system/xbin or /system/bin section you will not find a binary file format only wipe, and in other Linux systems too. There is a reformatting to another file system, but that’s another story that has nothing to do with wipe.

    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: the popular custom firmware CyanogenMod has 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 are a user of CyanogenMod firmware or you know that there is a script in the updater-script that performs this backup, then before installing the firmware it is better to also make a format system.



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

    Wipe cache partition

    Wipe cache partition is a way to clear a cache partition. This area stores temporary files that remain 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.

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

    Wipe is aimed at clearing memory sections of your device. Carrying out the operation leads to both the loss of personal data and the loss of downloaded applications. System applications acquire an 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 deletes the cache. With this method, personal data is not lost.

    Wipe Dalvik Cache: All your programs are in the Dalvik cache directory tree, wipe affects him, while personal data remains untouched.

    Which wipe in what case should it be used? What is its meaning?

    If you are installing a new ROM without committing wipe, then a lot of “garbage” remains from old system, which leads to unstable work new. You get a bunch of errors, crashes and other problems. For this reason wipe always necessary.

    Let's now look at which wipe to use in which case.

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

    If we're talking about O small updates, for example, you go from CyanogonMod 9.0 To CyanogenMod 9.1 or install, then you need to apply " Wipe Cache Partition" And " Wipe Dalvik Cache".

    That's all, actually. Now you know that wipe helps solve many problems associated with custom ROMs. If after installation a lot of errors occur in the system, you can easily eliminate them. If wipe does not help, then you need to use the "" option in recovery mode. We hope that now questions on the topic should be done wipe or not you won't have any problem.

    It's no secret that modern smartphones are real mini-computers, with their own operating system, many settings and a large selection of the most different programs. And as you know, the more complex the system, the easier it can fail. According to the most various reasons the phone starts to work slower, the battery drains faster, the phone may freeze and reboot on its own. Many users begin to panic, turn to familiar “programmers” or to various service centers. However, it is often possible to solve the problem yourself. If you have Android installed on your phone, you can try to restore the device yourself using a special function called Wipe data factory reset

    If we talk in simple words, the operation of this function resembles the process of reinstalling the operating system Windows systems on regular computer. Only in the case of a smartphone, the whole process takes much less time. Usually this procedure lasts no more than 5-10 minutes. And unlike the same reinstallation of the “OS” on the computer, here you will not need to install drivers from long and tedious motherboard, video cards and other equipment. All necessary programs and the components will be installed immediately. The only thing, after this procedure, you will be able to connect to the Internet and check for updates for your phone, and if there are any, install them. To the common man We need a translation of what wipe data is and why you need to reset this data, we’ll talk about this below.

    What problems can Wipe data factory reset solve?

    • Decrease battery life from battery;
    • Virus removal;
    • Clearing the internal memory of a smartphone
    • Freezes and slowdowns at work.

    In general, if there is any problem with your phone, the first thing to do is try using Wipe data factory reset. The only thing you need to remember is that, in addition to viruses, unnecessary files and useless programs, all settings, contacts and useful programs will be deleted.

    How to reset settings

    The English word wipe is translated as cleaning. In other words, this normal formatting memory. There are usually two options for this action - full wipe and partial.

    The first one deletes information from the entire memory. Using a partial reset, you can clean up individual partitions.

    Separately, I would like to note that before performing the procedure you need to make sure that accumulator battery phone is charged. Also, if required, you need to save all important information— contacts, photos and other files. IN wipe process data they will be deleted.

    In general, in the case of an Android phone, there are several ways to reset the settings.

    Reset via phone menu

    If the phone boots, you can try to reset it through the Settings menu - the icon with the image of a gear. Here you need to find the “Restore and reset” item. It is usually located at the very bottom of the list. On some phones it can be found in "Advanced phone settings".

    • We go to this menu, click on the “Reset to factory settings” item.
    • Then "Clear all". The system will display a warning message that the information will be deleted.
    • We give our consent.

    On some smartphones, for security purposes, you need to enter a special digital combination, which the system itself will issue. This is done to prevent accidental pressing and memory formatting. After starting the recovery process, the phone screen goes dark, then lights up again. At the same time, it displays the progress of the recovery process. After the process is completed, the smartphone reboots. After this, the start screen will open. Here you will need to perform the initial phone settings - select a language, specify your account information, connect to Wi-Fi networks. There is nothing complicated. Read carefully, then enter the data. Most items can be skipped altogether by clicking the “Next” button.

    Reset withrecovery partition

    This method is more complicated, but it helps even in severe cases. Often, you can use it to revive a phone that has stopped booting altogether or is unable to access “Settings.”

    To do this, you need to turn off your phone completely. Then we look for the volume buttons. Press the volume up key and hold it. Then, without releasing this button, press the power button of the smartphone. After the splash screen appears on the screen, release both buttons. If the phone supports resetting settings in this way, a special menu with several items will appear on a black background. In this mode, to control the phone you need to use the volume buttons to move through menu items and the on/off keys to confirm your selection.

    Select Wipe data factory reset. Confirm your choice by pressing once Power button. The phone will reboot and numbers and inscriptions will begin to appear on a black background showing the progress of the process. Recovery usually takes a few minutes. If everything worked, the phone will soon reboot and the screen will open initial settings, as in the 1st option. Sometimes you have to reboot the device manually by selecting Reboot.

    After execution primary settings, the phone is ready to use.
