• How to return the “old” Android firmware?

Returning the phone to standard firmware allows you to get rid of problems with the functioning of the software, various freezes and device failures. In this case, after resetting the settings (Hard Reset), the device’s firmware will return to its original state, in which it was installed by the manufacturer.

Android

Resetting an Android phone to the factory firmware is performed using the appropriate setting in the device menu or using a key combination (if it is not possible to turn on the phone). To reset the firmware of a phone that is turned on, go to the “ ” menu of the device. Then tap About Device and select Factory Reset. The name of the menu items for calling the reset operation may change depending on the version of the device’s operating system and the manufacturer that made changes to the standard firmware. If necessary, enter the security code to reset the software, and then confirm the operation.

If you want to return the phone to its factory state if it is impossible to start it completely, hold down the phone key combination, which can be described in the instructions for using the device, on specialized forums or on the official website of the device manufacturer in the technical documentation section. Most devices reset the version of their operating system and return the settings to factory settings when using a combination of the unlock (power) key, menu and volume down button. It is worth noting that some phones use the volume up key to reset settings. In this case, the power button can be released after the smartphone starts up, and the volume and menu keys should be kept pressed for a few more seconds before the formatting process begins.

You can also use the corresponding menu item to reset your iPhone. To do this, go to “Settings” - “General” - “Reset” - “Delete all content and settings.” Confirm the operation twice and wait for the phone to return to its factory state.

You can also reset your device using iTunes. Connect your phone to your computer and open iTunes. After that, select the device name in the upper right corner of the program. In the "Review" section, click on the "Restore" button. Remember that resetting the firmware will result in the loss of all saved settings and data, and therefore it is recommended to make a backup copy before carrying out the operation.

Windows Phone

Resetting the firmware of a Windows Phone is also performed using the corresponding function, which is available in the device settings. Click "Settings" and go to the "Device Information" section, then select "Reset settings". Confirm the operation twice and wait for the notification that formatting is complete to appear.

Some Windows Phone models can be reset to factory settings without having to turn on the device. To do this, hold down the Volume Down button simultaneously with the Power key. Release the power button. Once you see the phone logo, release the Volume Down key. Then press the volume up, volume down, power buttons, and then volume down again. After this, wait until the settings are reset and the corresponding notification appears on the screen.

Every year, Google releases a new version of its own operating system for mobile devices – Android. It is the most widespread and is ahead of its direct competitor from Apple – the iOS system. Its popularity among users is due to the greater freedom of action that this shell provides and the many settings that are not available to fans of Apple devices. But sometimes situations arise when it becomes necessary to roll back to an older firmware version. This is especially true in cases where the user initially did not uncheck the automatic system update settings item. But not everyone knows how to return the old firmware to Android.

Need for updates

Before we talk about how to return the old firmware to Android, it is worth mentioning why Google releases periodic updates. This includes not only global changes in the form of a completely new version of the OS, but also various patches or patches.

Their main purpose is:

• correcting identified bugs in the system;
• reduction in energy consumption (Android becomes less energy-intensive with each new update, which allows you to get longer battery life without increasing battery capacity);
• resolving hardware problems (this includes camera, sound, multimedia capabilities).

But not every user enjoys innovations. Some people dream of returning to the old firmware version after the next update.

This may be due to a disruption in the stable operation of the device, especially if a new version of the system is released that has not been fully tested on all supported devices. Innovations may also include additions in the form of services that cannot be removed.

It should be immediately noted that when deciding how to return the old firmware on Android, you must take into account that, unlike, for example, Windows, a smartphone or tablet does not have a default rollback function. Therefore, when returning to a previous version of the OS, you should be prepared to lose all data.

How to return old firmware on Android using a factory reset

The easiest way to “undo” the received system update is to roll back to factory settings. After carrying out these manipulations, the user receives a phone whose internal contents will be similar to the one he recently purchased.

To roll back using this method, you need to go to the desired menu item:

Getting the old firmware version via Hard Reset

The second way to roll back to an earlier firmware version is to use the standard Recovery menu. To gain access to these settings, hidden from the inexperienced user, you need to press a certain key combination.

The most common method is to simultaneously press the power button and the volume key (up or down). Some devices use triple clicking with the addition of a Camera button.

After entering Recovery mode you need:

After this, the device will reboot, as a result of which the user will receive a “new phone out of the box.”

Reflashing the device

Another way to return the old version on Android is to flash your smartphone. To do this, the first thing you need to do is download the required version of the software. This can be done on specialized forums. After downloading, you need to transfer the archive to a memory card, since it is from it that the firmware process will be carried out.

Operating system updates are always an expected event. Some phone owners find it difficult to wait for official patches from developers, so they choose a more affordable option - installing custom firmware, which is not always successful. There are also users who are frightened by innovations of this kind. This is understandable, because updates do not always help, they can even be worse than older versions. Sometimes fixes for certain programs load the system significantly, making the user experience more difficult, or are so useless that it becomes a little alarming. But the most disastrous result awaits users when the user interface changes irrevocably, naturally, not for the better.
Perhaps we should start with Nexus smartphones. The process of installing new firmware is incredibly simple: we save all the necessary information; On the Internet we find the required image of the version to which we want to upgrade, and carry out the installation. It is necessary to take into account that if you do not open root rights, then it will be impossible to create a backup of the current version of the operating system, as well as extremely important system data. The market also provides the opportunity to download applications that can be used to save almost all the information, but they require additional rights.
For Nexus smartphones it is much easier to return the old version of the application if you don’t like the new one. We simply find an older version of the apk file, completely remove the new application, and, using Explorer, install the old version. The main thing is not to forget to open access to install applications from other sources.
Regarding other devices (except Nexus), in particular, in matters of Android rollback to previous firmware versions, the situation is somewhat different. Some, even most, devices running on the Android system are not designed to change the firmware manually. Factory settings limit the ability of the user to interfere with the system files of the smartphone. These restrictions also need to be lifted independently. For example, first you need to unlock the bootloader. The installation of the old firmware version itself takes a little time, but preparing for the entire procedure may even require several hours.
Looking at all the nuances, the most reliable option for updating the system to a more recent build is to use custom firmware. We have already indicated this method a little higher in the context, but now we will try to substantiate the fact why this option is much better than rolling back the Android system to older versions. First of all, reliable assemblies are free of inaccuracies and errors, because huge teams of professionals work to create these updates. Secondly, you have the opportunity to choose the most suitable firmware. Thirdly, if you make every effort, you can always find an update with a better design.

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.

Activating file backup

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.

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.

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.

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. .
