Restore factory settings on bq phone. All the ways how to reset the settings on the android device to factory settings. Using service combinations

Often, to solve software problems with the functioning of modern smartphones or tablets, you should perform a Hard Reset (hard reboot) or reset the android to factory settings. In many cases, this helps to get rid of device freezes due to incorrect operation of some applications, "junk" system files, viruses, etc.

Is it possible to return the phone to factory settings

The ability to reset data is supported by any device on Andriod, so every owner of this system can do it. Before you return the factory settings to your android, you should understand that at the same time you will completely lose all data except for those that are written to the memory card. It will no longer be possible to restore their capabilities; rollback of such actions is impossible. If you decide to reset the device to the factory state, then you will lose:

phone book entries;
applications;
photographs, music, books;
saved logins and passwords to accounts.

How to reset settings on android

Before carrying out this procedure, it is strongly recommended to copy important files, information (photos, videos, music) to the computer via a cable. It is better to make a full backup (copy) of the system, so that in case of unsuccessful resetting, you can restore the device's performance. There are 3 main options for how to reset android to factory settings:

through the phone menu;
using a combination of buttons;
service codes.

Reset in phone settings

The easiest way to reset android settings to factory settings is the gadget menu. For this, the device must work and be able to go to the main section of the system. For all smartphones with Android 4.0 or older, the procedure is as follows:

Go to the main menu.
Click on the "Settings" section.
Find the "Recovery and reset" section.
Scroll down the page and find the "Factory data reset" section.
The system will inform you that the data will be deleted from the smartphone. Click on the line "Reset phone settings" and confirm the desire to "Erase everything". Items may differ slightly from phone to phone, but the names are always the same.

Using service combinations

This method also requires the device to turn on and be able to go to dialing. Each manufacturer programs their devices with special combinations that help to return to the factory state. This applies to both global brands (Samsung, HTC, Sony) and Chinese low-cost models. Codes can change over time, they need to be clarified on the manufacturer's website, sometimes they can be found in the manual for the smartphone. Below are examples of such combinations for your reference:

*2767*3855#;
*#*#7378423#*#*;
*#*#7780#*#.

Key reset with Recovery

The most radical method on how to reset the settings on an android to the factory settings is the Recovery menu. This is the best way to return to the original state of the smartphone if it hangs on the screensaver with the company logo and does not turn on. Each device model has a standard button combination that switches it to the Recovery menu. Sometimes you have to use recovery if:

the slowdowns in the phone have become too strong;
the system prevents you from deleting, transferring or changing anything.

First, turn off your phone completely. Wait until the buttons go out, the screen. Next, you need to find a suitable combination for your model (the combination for HTC and Samsung will definitely be different). You can use one of the options:

button "decrease the volume" + "turn on" or "Power" (the most common combination);
on some LG phones, you need to press the above keys, wait for the logo, release the "power on" and then press it again;
"Volume up" + "volume down" + "on"
"Power" + "Home".

Hold one of the combinations until you are put into recovery mode to reset the device to the factory state. The menu is controlled by the buttons to increase and decrease the sound. If the Recovery version is touch-sensitive, then you can reboot in the standard way (by touching the screen). To confirm the selection, you need to press the "Power" or "Context Menu" button. Next, to reset your phone to its initial state, you need.

Long-term use of a smartphone leads to slow operation of applications, and the device as a whole. Vin most cases, users uninstall some applications or install tools that speed up the phone. But this is not so, you will rather load the device even more. And here is a worse example: the phone does not turn on, although it is charging, which means you can reanimate, you forgot your password, pin code or pattern. In this case, you need to know... I will try to describe all the methods in as much detail as possible in this article.

How to reset your phone to factory settings using Recovery

I talked about Recovery, this is the fastest way to get rid of headaches. It is worth noting that the functions there are in English (unless you have TWRP or CWM recovery). Here are some of the things you need to do:

Turn off your smartphone completely;
Find on the Internet or on our website how to enter the recovery (using a combination of buttons). Usually, the off, volume and home keys are pressed at the same time;

Going into the recovery, you have to find the option "Wipe data / factory reset"... In other types of recovery, "Reset" may be written.

If you have CWM Recovery, then the command will be the same as just above. If TWRP (Team Win Recovery Project), there is a function - Wipe or Cleaning.

By choosing this option in CWM, you agree, when the option appears "Yes - delete all user data".

If you have TWRP, select Wipe / Cleaning and carry out swipe to the right to clear Data, Cache and Dalvik. This is usually enough to clear your phone.

It should be noted that all data in the phone's memory will be deleted. In some firmwares it is possible to mark the function of deleting files from memory cards.

Hard Reset with Engineering Codes and Dedicated Reset Button

There are special codes for resetting the phone. Before entering them, I advise you to think about important files and transfer to another drive. It is advisable to remove the USB flash drive, since it is not known how this or that code works on different devices.

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

I want to note that some firmware, for example, from Samsung, does not allow the use of some engineering codes. If it doesn't work out for you, just use other methods.

The last item is a small button inside the phone, when pressed, the phone is reset to the factory state. Unfortunately, it is no longer integrated into modern smartphones.

If you have problems with your PC, then read about.

If not included in Recovery

When you press the combinations of buttons to enter Recovery, an Android icon with an exclamation mark may appear. In this case, click "Inclusions" + "Volume Down" or Volume Up.

Not a single user can be insured and is 100% sure of the quality of his mobile phone, and even more so in the reliability of the operating system and other installed applications. Perhaps smartphones have become smarter, more convenient, but the problems in many cases remain the same - complete phone failure, the appearance of non-standard errors, glitches and freezes, mute and much more. As a rule, in the Android operating system, most problems can be solved on their own, and at the same time it is not necessary to carry the phone to the nearest service center, having paid several thousand rubles for actions that you can perform yourself without much effort.

In this article, we will tell you how to reset the settings on Android to the factory settings, what it is for, what the consequences will be after the reset.

Why use this procedure?

One of the reasons why this option is used is to delete confidential information, for example, if you sell your phone to another person and do not want any information about you to remain. In case of theft, this method will not work, but you can use the option to remotely control your device to erase the data immediately after turning on the phone.
Another reason, according to which the settings are reset, is the appearance of errors and problems of a system and software nature.

What will the user lose from their device?

If you decide to reset the settings, you should understand that the system will automatically remove all programs that you installed through file managers or the Gooogle Play service, completely clear your chat history, SMS, delete contact information, mail accounts and much more. The phone memory will be completely cleared, but the SD card will remain with all the data! Basically, you will get a “clean” smartphone, as if you just bought it in a store.

If you do not want to lose data, then create backups in order to restore them in whole or in part later. We also recommend that you copy some of the photos and videos to a PC or another phone with a certain period of time.

How to do a factory reset on Android

There are three ways in total, and they differ significantly from each other. Let's analyze each of them in detail:

Reset in phone settings
Reset with service codes
Reset by keys

Method 1. How to reset Android phone to factory settings using the menu

All operations will be carried out from the main OS Android menu. You need to go to the "Settings" item, select the tab called "Privacy" there, and then click on the "Reset Settings" tab.

As you can see in the photo above, here you can activate the following items:

"Archiving data" ("Copying data")- The system will automatically save copies of all applications installed on your device, settings from Google services, as well as data on each Wi-Fi network previously saved in the phone.
"Auto-recovery"- All programs will be automatically restored with all settings.

Click the "Reset settings" item and confirm your desire to erase the data. You will see a window with a list of data that is deleted after a factory reset. As soon as the phone restarts, you can reinstall any programs, add accounts.

Method 2. Reset service codes

In the Android system, as in any other (Java, Symbian), there are special codes with which you can activate the restore operation to factory settings.

Attention! The codes may change, they may not be suitable for your model or version of Android, so follow all the operations carefully! We are not responsible for all actions, and we provide information with codes for review.

Here are some codes. You will need to go to the dialing mode of the phone and enter one of these:

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

Method 3. Reset with keys (using Recovery)

Each Android smartphone has dedicated keys that you can use to initiate the factory reset process. Since most phones at the moment are provided with a touch screen, the volume keys, the Home button, and the power key are mainly used for resetting.

Here is a sample list of buttons that will allow you to reset your settings:

"Volume down" + "Turn on the device". This is one of the most common combinations used on many phones. Try it first. If it doesn't work, see the list below.
"Volume up" + "Volume down".
Power on device + Home key + Volume up.
"Volume up" + "Volume down" + "Turn on the device".
Volume Up + Home key.

You need to hold and press the keys at the same time. The approximate retention time is 2-5 seconds. As soon as the system enters a special mode - Recovery, a menu will appear on your screen.

To move through the list, use the volume up and down keys, because the devices are mostly touch-sensitive!

Find the wipe data / factory reset item and click on it. Sometimes this item is not on the list, but instead there will be one of them: Clear eMMC, Clear Flash! As soon as you click on the selected tab, the system will ask for confirmation.

Select the Yes item, and at the end click the Reboot System menu item - this is the restart of the operating system.

In some versions of Android, the presented items may change, depending on the version, but basically the same type of menu is used. We also strongly recommend that you look at the manual of your mobile device before calling the menu or using the codes. Sometimes there are already registered service codes and keys for resetting the settings.

If the device cannot be restored after a factory reset or errors and glitches remain, take the phone under warranty to the store where it was purchased or contact the service center if the warranty has already expired.

The need to reset Android settings can arise in completely different situations: the device starts to freeze, or you simply cannot unlock it. And if no action helped to solve the problem, Hard Reset is a real opportunity to restore the device's performance. This article will tell you what to do.

(!) If you forget your pattern, PIN or password, read these instructions first: and.

Well, if after these manuals you still need help with unblocking or you have other problems with the device, read this article carefully. It is worth noting that after a Hard Reset, only data from the internal memory will be deleted from the phone or tablet. Files on SD, photos, music, videos, etc. will remain intact.
