The smartphone is not reset to factory settings. How to reset settings to factory settings on Android. How to do a hard reset if Android won't boot

Smartphones and tablets running the Android operating system have decent functionality and allow you to solve a variety of tasks. They run various applications, store photos, videos and other data. Sometimes there is a need to get rid of everything that is stored in the system at once. Manually deleting data is too time-consuming, so it is easier to return the device to its original state by instantly wiping it.

How to factory reset Android OS? There are many ways, which we will talk about in our review. Why do you need to reset the operating system and the entire device to its factory state?

When transferring or selling the device to another user;
If the Android operating system does not work correctly;
If it is impossible to start the operating system;
With numerous errors in the operation of programs and the OS.

The result is a complete wipe of the Android device to its original state.

Reset via main menu

Do you want to sell a smartphone or tablet? Do you need to get rid of errors in the functioning of your operating system and applications? Then we will tell you how to reset Android to factory settings and clear the device of installed programs and data in memory. The easiest way to perform a reset is to go to the main menu, select “Settings”, select “Activation and reset”, click on the “Data reset” line.

What happens next? So we will receive a warning that all data will now be deleted from the device– accounts, photos taken, downloaded music, work files, as well as access keys to encrypted files on the memory card. All accounts under which you are logged in on this device will also be listed. At the very bottom you will find the “Reset device” button - press and wait until the system returns to its original state.

Please note that a hard reset does not affect data stored on the memory card - photos, videos and data stored here will remain safe and sound. But we recommend removing the memory card when performing a master reset.

Android Engineering Codes - Factory Reset

As a result of various errors, some menu items may not be available. And it will be impossible to reset Android to factory settings. What to do in this case? The easiest way is to use one of the engineering commands available in all versions of the Android operating system and on all devices. The command *2767*3855# will help you perform a full reset - she is dialed in a regular dialing program.

If for some reason the command did not work, you can use another command - *#*#7780#*#*. Just like the previous command, it will help you perform a Hard Reset (resetting Android to its factory state. If this does not help, try typing the third command - *#*#7378423#*#*. After the reboot, you will receive a clean device returned to original factory condition.

Do not use commands whose purpose you do not know, as this may lead to the loss of functionality of your device.

Resetting Android via Recovery

The Android operating system may become so damaged that it becomes impossible to start. A typical sign of damage is the device loading endlessly. The only way to bring the device back to life is a Hard Reset (master reset) through Recovery mode. To access this mode, use the following combinations:

“Power on” and “Volume down”;
“Power on” and “Volume up”;
“Power”, “Home” and one of the volume keys;
"Power" and both volume buttons.

You need to press the buttons when you turn on your smartphone or tablet. For some models, additional actions are performed by pressing certain buttons after turning on the device using the above combinations. Thus, in order to restore factory settings on Android, you need to look for a key combination that allows you to enter Recovery mode on your device (usually this mode is used to flash Android devices).

Next, select “wipe data/factory reset” and wait until the return to factory settings is completed. Please note that all data on your phone will be deleted. Therefore, you should not neglect creating backup copies to avoid losing this data.

Do not touch other items in the engineering menu or in Recovery mode under any circumstances - this can lead to the most unexpected consequences, including the complete loss of functionality of the device and the impossibility of its further restoration.

Let me remind you that Hard Reset is a reset to factory settings. Therefore, based on the name of this operation, it follows:

Factory reset protection - protection against factory reset:

Attention! Since version Android 5.1 and higher Phone manufacturers have introduced so-called factory reset protection. It was introduced to protect access to your personal information and to prevent a potential thief who happens to have your phone from using it.

Therefore, if you created a Google account on your phone before resetting the settings, then after the reset the phone will ask you to enter your email and password for your Google account. Hard reset on Android 6.0 and higher will not delete Linking your phone to your Google account.

If you are going to do a hard reset on your phone, then ALWAYS make sure that you know the access data for your Google account\mi account\Flyme account, etc.

Also, before resetting, you can first log out of your Google account (Settings > Accounts > Google > button with three dots > delete account). In this case, after resetting the settings, the phone will not ask for any logins or passwords and you will be able to use your device.

In case you have already reset the settings and cannot remember the username and password to log into your Google account, for most models there are instructions for bypassing this protection (FRP). Enter a query using the following template in Google search: [Your phone model] frp or [Your phone model] reset Google account.

However, it is not possible to bypass this protection on all smartphones. Owners of some phone models, especially the newest ones, will have to contact the official service center with a receipt.

Consequences of Hard Reset

After performing a hard reset, your device will be completely wiped. The following data will be lost: personal settings (color schemes, home screen settings, etc.), messages (SMS), contacts (which were in the device memory), notes, installed programs, games, photos, videos, files. Everything that was in the memory of your device will be deleted. Contacts on the SIM card and data on an external (removable) memory card (SD card) will not be affected.

What can you do to avoid losing important information?

If important information remains in the memory of your device (contacts, SMS, photos, videos), then there are the following options for saving it:

synchronization with Google contacts, Google Drive (if your device runs on Android)
DropBox storage and synchronization service
creating a backup using Titanium Backup
transferring important data to your PC (computer) using service programs for your smartphone/tablet model

If there is no way to save data before Hard Reset

If for some reason you are unable to back up your data before performing a factory reset, there is a chance to restore some data after the reset. Fortunately, there is such a program called “7-Data Android Recovery”. Therefore, if you have already done a Hard Reset and have a “clean” phone/tablet in your hands, do not rush to get upset - using this program you can try to restore old files. Read more below.

Hard Reset, also known as Hard Reset, is done in two main ways. Regardless of the method you choose, take care to back up your personal information, and also remove the memory card from your tablet and, just in case, a SIM card, if you have one.

2. Through the Recovery menu (if the tablet does not turn on)

If a software failure occurs in the tablet, it stops starting, there is an “eternal loading”, or the device is locked with a pattern key - you have only one way out - get into Recovery mode, i.e. recovery mode. The Recovery menu can only be accessed when the tablet is turned off. To do this, use a special combination of simultaneously or sequentially pressed physical buttons on the tablet, which are located on the device body.
