There are situations when rolling back a device to factory settings - The best decision emerging problem. You can perform a reset in several ways: through the resettable device itself or using a computer. .

Why reset?

Hard Reset - rolls back the operating system to default values. When you perform a reset, all files and third-party applications are deleted from the device's memory, and all settings return to factory settings. By resetting the system, you will receive a clean device, that is, it will be in the same form as it was in the store.

A reset may be useful in the following situations:

The device started to freeze due to large quantity installed programs;
the system began to freeze due to overloaded memory;
there are a lot of files left in the file system from deleted applications that take up free space;
the device is for sale, so you need to remove all personal information from it;
I need to reset my password because it was forgotten.

As a result, it turns out that the reset must be performed when it is necessary to format the device.

How to save data

Since a system reset erases all data (videos, photos, music, pictures, books and other items) from the device, it is strongly recommended to think in advance about how to save all important information. The easiest way is to transfer all important files to a memory card or computer. When resetting, items stored on the SD card, even if it is inserted into the device, are not deleted, but just in case, it is better to remove the memory card during the operation.

Another way is to create a backup copy in which all files will be stored. After performing the reset, you can restore your system from a previously created backup, and all items and applications will be returned. Positive side This method is that you will not lose not only files, but also applications. Negative side- if the reset is carried out in order to clear the device of unused files, then when restoring from a backup, the files that you wanted to get rid of will also be restored.

Copying is done using Google service and only via Wi-Fi, since the amount of information is too large to be downloaded via Mobile Internet. Go to your device settings, open the Backup & Reset tab and make sure that the automatic backup feature is enabled. The copy will be linked to your Google account, and you can recover from it after you perform the reset. The device itself will prompt you to use the found copy.

If you have a turned off device, but there is no way to turn it on, then this method will suit you:

Via computer

This method will help you enter the recovery menu if the previous method failed for some reason. Connect the device to the computer using a USB adapter and select “Charge only” in the connection type. Download the archive with the ADB program and unpack it into any folder, the path to which does not contain Russian letters.

Click on the button that appears, you will be asked to log in to your Google account, which was previously linked to this phone or tablet. If you log into the correct account, you will have the opportunity to reset your existing password.

Reset password via ADB

The second option is to reset your password using ADB. How to install this program is described above in the “Via a computer” subsection. When you are done with the installation, launch a Command Prompt as an administrator and run the following options:

adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name=’lock_pattern_autolock’;
update system set value=0 where name=’lockscreen.lockedoutpermanently’;
.quit

If these commands do not help, then use the command adb shellrm /data/system/gesture.key or adb shell
rm /data/system/gesture.key.

How to recover data after a reset

It was previously described that in order to save data, you need to back up your files in advance or transfer all important elements to another medium. If you did not do this, but at the same time reset the device, then you most likely will not be able to recover the lost information. But it’s worth a try: get root rights on the device, and download to your computer some program designed to recover deleted files on Android. For example, you can use EASEUS Mobisaver for Android Free.

There are two ways to restore your device to factory settings: through the device settings or the recovery menu. You can enter Recovery Mode both from the device itself and using a computer. Before resetting the system, be sure to transfer all important information to a reliable third-party storage device. .

It's no secret that when using Windows for a long time, the system begins to work slower, or even outright lag. This may be due to the clogging of system directories and the registry with “garbage”, the activity of viruses and many other factors. In this case, it makes sense to reset the system parameters to their original state. Let's see how to restore factory settings on Windows 7.

There are several methods for resetting Windows to factory settings. First of all, you need to decide how exactly you want to reset: return the original settings only to the operating system, or, in addition, completely clear the computer of all installed programs. In the latter case it will happen complete removal all data from PC.

Method 1: "Control Panel"

Reset Windows settings can be done by launching the tool required for this procedure through "Control Panel". Before activating this process, be sure to.

Click "Start". Go to "Control Panel".

In the block "System and safety" choose an option "Archiving computer data".

In the window that appears, select the lowest item "Restore system parameters".

Next, follow the inscription "Advanced Recovery Techniques".

A window opens containing two parameters:
- "Use a system image";
- "Reinstall Windows" or .
Select the last item. As you can see, it may have a different name on different PCs, depending on the parameters specified by the computer manufacturer. If your title is displayed “Return the computer to the state specified by the manufacturer”(most often this option occurs on laptops), then you just need to click on this inscription. If the user sees the item "Reinstall Windows", then before clicking on it, you need to insert the OS installation disk into the drive. It is worth noting that this must only be the copy of Windows that is currently installed on the computer.
Whatever the name of the above item, after clicking on it, the computer restarts and the system is restored to factory settings. Don't be alarmed if your PC restarts several times. After completing the specified process, the system parameters will be reset to their original settings, and all installed programs will be deleted. But if desired, you can still return the previous settings, since files deleted from the system will be transferred to a separate folder.

Method 2: Restore Point

The second method involves using a system restore point. In this case, only system settings will be changed, and downloaded files and programs will remain intact. But the main problem is that if you want to reset the settings exactly to factory settings, then to do this, you need to do this as soon as you purchased a laptop or installed the OS on your PC. But not all users do this.

So, if you have a restore point created before you started using your computer, then go to the menu "Start". Choose "All programs".

Next, go to the catalog "Standard".

Go to the folder "Service".

In the directory that appears, look for the position "System Restore" and click on it.

The selected system utility is launched. The OS recovery window opens. Just click here "Further".

Then a list of restore points opens. Be sure to check the box next to "Show other restore points". If there is more than one option, and you do not know which one to choose, although you are firmly convinced that you created the point with factory settings, then in this case, select the earliest date point. Its value is displayed in the column "Date and time". Having highlighted the appropriate item, press "Further".

In the next window, all you have to do is confirm that you want to roll back the OS to the selected recovery point. If you are confident in your actions, then press "Ready".

After this, the system reboots. It will probably happen several times. After completing the procedure, you will receive a functioning OS on your computer with factory settings.

As you can see, there are two options to reset the operating system to factory settings: by reinstalling the OS and returning the settings to a previously created restore point. In the first case, all installed programs will be removed, and in the second, only system parameters will be changed. Which method to use depends on a number of reasons. For example, if you did not create a restore point immediately after installing the OS, then you only have the option that was described in the first method of this guide. In addition, if you want to clean your computer from viruses, then only this method will do. If the user does not want to reinstall all the programs that are on the PC, then you need to use the second method.

A factory reset may be necessary in several cases. For example: if there is a problem with your device and you cannot solve it, or you want to sell your device and do not want your personal data to fall into the wrong hands.
