Hard reset on an Android phone. How to do a Hard Reset on an Android device. Correcting errors in the engineering menu

There are situations when rolling back the device to factory settings is the best solution to the problem that has arisen. 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 began to freeze due to a large number of 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 that you think about how to save all important information in advance. 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. The positive side of this method is that you will not lose not only files, but also applications. The negative side is that 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 carried out using the Google service and only via Wi-Fi, since the amount of information is too large to download via the 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.

Reset the device

There are several ways to reset your device. The easiest one is through the system settings.

Through settings

This option can be used if you have access to the system. If you have forgotten your password, or the device freezes at the boot stage, preventing you from logging in, then use the method described below.

Through the recovery menu

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. In the resulting folder, create a file called devices.cmd, where cmd is its extension, and write three commands into it:

  • echo off
  • adb devices
  • pause

Run the created file, a command line will open on the screen with the following commands already written:

  • D:\adb>devices.cmd
  • adb devices
  • List of devices attached
  • HT16GV402012 device
  • D:\adb>pause
  • To continue, press any key...

Done, the program is installed. Now open a command prompt as an administrator and use the adb reboot recovery command in it. Your Android device will automatically be transferred to the recovery menu, and the further steps you need to perform to reset are described above in the “Through the recovery menu” subsection.


Enter Recovery Mode via computer

What to do if the password is not reset

If you reset your device in order to remove a password from it that you forgot, and after finishing the procedure the system still asks you to enter it, then there are two ways out of this situation. The first is to enter the wrong password five times, a message will appear on the screen stating that the device is locked for 30 seconds, as well as a “Forgot your password?” button. 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.

Recovering the device password via Google account

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 create a backup copy of 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 it will most likely not be possible to restore 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.


Recovering deleted files using 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. .

If your Android device is not working correctly, and you are absolutely sure that there are no other ways to fix the problem, you can use the hard reset procedure at any time - a hard reboot of the system and returning the device to its factory state. Hard Reset can be done in several ways. From this article you will learn how to do a Hard reset on Android, three different ways. As an example, I used an HTC EVO 3D phone with the Android 4.0.3 operating system installed.
In order to do a hard reset, you need:

Hard reset. First way:

1) Go to Menu - Settings - Memory;

2) Select a sub-item Reset to factory settings, after which a dialog box will appear indicating exactly what data will be deleted as a result hard reset;

3) If you are really sure that you need to do a hard reset, you should tap on the item Resetting your phone. Otherwise, press back;

4) After the previous step is completed, the system will once again ask whether you really want to reset the settings and delete all personal information, as well as all downloaded applications without the possibility of recovery;

5) If you confirm, the hard reboot procedure will begin.

Hard reset. Second way

We dial the code in the dialer *2767*3855# . Attention! After you have entered the code, the device will immediately reboot. Deletes all data in the built-in memory, the data on the memory card remains (but to be on the safe side, it is recommended to remove the memory card from the phone).

Hard reset. Third method

Enter mode. For example, in HTC it is done like this:
1.First, you need to turn off your phone. If the device is frozen and you cannot turn off the power using the standard button, then just remove/insert the battery. Wait until all function buttons go out.
2.Next on the device you need to simultaneously hold down the following keys: power button ( Power) And decrease volume level (-).
3.A menu will appear in front of you, in which you should select the item “ Factory reset(clear storage)". The cursor moves through the list using the volume control rocker, and the desired item is selected by pressing the power button ( Power).


4.Next you need to reboot the system, that is, reboot the phone. To do this, select the appropriate item in the menu or hold down the power key ( Power).
5.After the completed operations, the device will turn on with the data already cleared and with factory settings.

Surely you will agree that a Lenovo phone is one of the best options for mobile gadgets. It works on Android and is quite reliable, and it’s quite inexpensive. Nevertheless, no matter which Lenovo model you choose, sooner or later there will be failures in the operation of the initially made installations. This is quite logical, since any technique is not ideal. This can happen due to an ill-considered installation of third-party software, or simply if you have not updated it for a long time. In such a situation, the question arises: how to reset settings on Lenovo? Don't worry, everything is quite possible to do! Resetting to factory settings on a phone is no more difficult than on a computer.

What do we do if there is a need to reset all settings on a computer or laptop? If a tough and decisive measure is needed, then we reinstall the operating system by going into Bios. This is a safe but radical method - reinstalling the OS via BIOS leads to the loss of all data. You could try to do this on Lenovo if you have a laptop manufactured by this company. For example, lenovo g50, lenovo a2020, lenovo g580, lenovo b590, b50, g50-45, S 40-40, etc.

Restoring factory settings on a Lenovo phone or tablet is also called Hard Reset. With its help, you can completely reset all parameters, but remember that the stored information will be deleted and will not come back.

The need to return all factory settings of the phone arises in the following cases:

  1. The device started to work slowly.
  2. When loading certain applications (or any), the system freezes seriously.
  3. The phone is infected with a virus.

There are two main ways to reset Lenovo. The first of them involves working in the phone menu, and the second involves using physical buttons. We will talk in more detail about how to do a hard reset using each of them.

Factory reset via menu

A complete reset via the phone menu is possible as follows:

  1. Go to the “Settings” section.
  2. Find the item “Restore and reset”.
  3. Click on “Reset”.

Before performing a factory reset, the BIOS will ask you if you are sure of your actions. After all, if the system did not do this, it would be possible to reset all Lenovo settings by mistake. If you reset Lenovo consciously, then confirm your actions, and after a few minutes the smartphone will reboot, after which the presets will be reset automatically.

The first time the smartphone turns on takes a long time, but don’t worry - this is how it should be. When it turns on, indicate your wishes regarding the basic parameters of the device’s operation and check whether the newly configured gadget works correctly.

Reset to factory settings via buttons

Now we reset Lenovo to factory settings in a different way. We will use physical buttons. This method of returning to the original system data is especially relevant if the BIOS is infected with a virus and you cannot even turn on the gadget. This reset Lenovo is done as follows:

  1. Press and hold the volume button and the power button at the same time. We hold them for about 10 seconds.
  2. After this time, you will see the Android logo on the screen. This means that the buttons can be released.
  3. After a while, Recovery will open, and using the volume down and up buttons, select the item we need - Wipe Data. This will allow you to do a Hard Reset of all settings.
  4. The BIOS will again ask if you are sure that all data has been deleted. We agree, pressing the volume up button and restoring the system.
  5. After rebooting and setting the settings, the phone works like new.

How to roll back settings on a Lenovo tablet?

You already know how to return the system to its original state on Lenovo phones. But what if you want to reset the software of your Lenovo 30 or 7600 tablet? This task is easy to complete! All you have to do is do the same as with a smartphone. The tablet settings also have a factory reset function, and as you know, the volume and power buttons on these gadgets are similar. The only difference is the location - the power button is usually on top, not on the side.

Thus, you can reset the system on any Lenovo mobile device, and you will not be afraid of any software failures.

How to reset Android to factory settings with just a couple of clicks? We'll tell you! Has your phone become too slow, freezes when loading, or won’t turn on at all? It is necessary to restore the system to factory settings. Resetting your Android phone to factory settings is not as difficult as it might seem at first; in this article we will describe in detail the entire process from A to Z.


Content:

Has your phone become too slow, freezes when loading, or won’t turn on at all? It is necessary to restore the system to factory settings. To switch to Recovery mode, you need to turn off the phone and then press the key combination. Each manufacturing company has individual combinations.

The most common is to simultaneously press one - or two - buttons that control the volume level and the “Power” key. The most popular companies use the following combinations:

  • “LG” - “Power on” + “Volume up”; after the logo appears, release and press this combination again;
  • HTC, Nexus, Xiaomi – “Power on” + “Volume down”;
  • Lenovo and Motorola – both buttons responsible for volume + “Power”.

After loading Recovery mode, the user will see system lines with different names. Select the line “wipe_data/factory_reset” and confirm the selected action. The phone will perform an operation for some time to reset new and restore old settings. Upon completion, the owner of the gadget will only have to click the line “Reboot_System_Now”. The phone will first turn off and then reboot with the restored Android system.

The phone must be turned on. To return your Android device to factory settings, go to the general settings section. There we find the “Restore and reset” item, where we select the “Reset settings” action. After this, the system will warn the user about deleting the data and ask you to confirm the operation. After completing the procedure, the phone will reboot and launch the operating system with the old settings.

The owner of the phone must go to the dialing menu and enter a code combination consisting of numbers and symbols. Manufacturers program their products differently, and the codes change over time. Therefore, for each specific model, especially less common ones, it is better to check the code on the Internet.

However, there are a few of the most popular combinations:

  • *#*#7780#*#
  • *2767*3855#
  • *#*#7378423#*#*

After entering one of them, the system will return the phone to its original software state.


How to avoid losing data when resetting Android settings

Restoring default settings will result in the loss of all data stored on the phone. All programs, documents, video and audio files, pictures, passwords and contacts are deleted by the system.

  1. Transfer data to micro SD drive. If you purchased an external drive when purchasing your phone, all the necessary information can be copied to it using a file manager. If you do not have a card, you can purchase it immediately before you return the factory settings to your Android smartphone.
  2. Data from your phone can be saved by uploading it to the Google Drive application. In essence, this program is an analogue of “cloud” storage. The user can download and store 5 GB of various information, and if he pays extra, this volume can be increased up to 1 TB. The application is installed from the Google Play market.

A little advice: In addition to saving data on a micro card, copy all important information to your computer. In this case, even if something happens to the external drive, the necessary information will remain with you.

If the user of an Android device has forgotten the password that unlocks it, and no recovery methods have worked, they will have to resort to resetting the settings. This can be done, firstly, by using the Recovery menu (the method is described at the beginning of the article).


Or here’s another way to restore factory settings on an Android gadget. So, the phone is turned on, but locked. When the system prompts you to enter your password, ask someone to call your number. During a call, the user has the opportunity to access the settings menu. Without accepting a call, you need to go to this section and select “Reset all data”. We confirm the operation. After restoring the original settings, the password requirement will disappear.

This brand of phone is one of the most common, so it’s worth mentioning separately. In particular, for Samsung gadgets, to exit to Recovery, press (simultaneously): “Power”, “Home” and the volume key “+”. The combination must be held until the menu appears.


If the reset is performed through the settings menu, you should select the “General Settings” section and go to the “Reset” item (it may also be called “Privacy”, “Backup and reset”). At this point, select the action “Reset data” (or “Reset device”). After confirmation, the phone will return the system to its original form.

How to reset Google account settings on Android

Typically, resetting your settings will require you to re-enter your Google account password. Don't remember this information? There are several ways to solve the problem. The simplest one is as follows.

After you have reset the settings on your Android phone, turn it on. Let's connect to the Internet. When filling out your Google account, write and select any few letters in your email field. A menu will appear above them, offering a choice of one of the actions: select, copy or send. Select “Send”. We indicate “SMS/MMS” as the program that will do all this. In the addressee line we indicate “112”, and in the message we enter a few letters of any kind. After sending, the system will send an SMS indicating that our letter was not delivered. This is what is required. You should go to this SMS message and press the “Call” button located next to the recipient’s number. This action should take the user to the contacts and dialing menu, where you need to erase “112” and dial the code: “*#*#4636#*#*”. The system will display a menu of several items. We choose the second one (something related to statistics). This will move the user to the settings menu, where a new function will appear in the “Reset and Recovery” item - resetting data with deleting the Google account.

Android factory reset apps

Did the above methods on how to reset your Android phone to factory settings not work? You can try downloading one of the specialized applications. These programs independently perform a system rollback to its original state. Examples include:

  1. "Simple Factory Phone Reset"— upon startup, it opens a screen with a white background with a large “Start” button in the middle, which begins the process of “rolling back” the settings. Able to remove “buggy” programs individually without affecting system data;
  2. "Phone Hard Reset"— after launch, displays a menu with two windows. One of them suggests reading the instructions, and the second one resets the settings;
  3. "Phone Factory Reset"- performs a complete rollback and reboot of the system. In the main menu of the program you need to click “Full Factory Reset”.
