The main reasons why the Android system does not update. Android update. What are the consequences of Android OS updates for a phone or tablet? If you update Android, everything will be deleted or not

Updating the Android version on your phone to latest version We'll tell you in the article! Many Android smartphones and tablets receive regular updates. The only exceptions are devices from little-known Chinese companies and very budget devices.

Why update Android

Some users of devices running this OS are wondering: should they update Android, and if so, why do it? This is highly recommended, since installing updates:

fixes security issues;
improves system performance and stability;
brings new features.

As a result, after updating, the device becomes less susceptible to security threats, runs faster and provides better convenience use (usability).

You can check this in three ways:

on the official website of the device manufacturer;
on specialized forums (for example, w3bsit3-dns.com);
by launching the application to update the device over the Air.

How to find out the current Android version of your device

To check which OS version is currently installed, do the following:

go to the settings menu;
scroll through the items to the last one - which is called “About phone” and tap on it;
Opposite “Android version” you can see the one present on the device.

Important: many Chinese manufacturers create their systems based on Google's OS. Therefore, in addition to the version of the “Green Robot”, you can also find out about the version of the operating system itself from the specified menu. Often, after an update, it is the latter that changes, while the former remains the same.

Why doesn't Android update automatically on my phone?

Most often this happens for three reasons:

First– the manufacturer did not provide for the possibility of an update over the air. In this case, the system does not have a proprietary application and the standard one has been removed, which checks, downloads, unpacks and replaces the corresponding files.
Second– the corresponding function is disabled. To activate it, you need to go to the program that performs the update, find this option there and enable it. You can read about activating the standard Android update tool in the “Over the Air” subsection.
Third– the software updater is prohibited from accessing the Internet. Many phones/tablets can be used to block network access using a built-in application.

Separately, it should be mentioned that automatic updates may not occur because the device manufacturer simply does not release updates.

Updating a system is not reinstalling it. Therefore, after it, absolutely all data that was present on the phones at the time of initialization of the process in question is saved.

Moreover, 90% of users have contacts synchronized with the Google cloud. The only exceptions are those who intentionally disabled this opportunity or uses a device that completely lacks services from the specified search giant.

That is, when synchronization is enabled, contacts will be saved even if the OS is completely reinstalled. They will even appear on another phone if you log in with your GMAIL account.

Methods to update the Android version

There are three ways to install updates: over the air - the easiest, through a PC - the most complex, using applications - very unsafe.

Updating Android over the air

In order for the device to receive updates over the air, it is necessary that the developer provide for this possibility. It, in turn, is available in almost all devices over $100.

Over-the-air update involves checking for the latest patches via the Internet (wi-fi) using the phone's built-in tools. If they exist, then special program downloads them to the device and replaces the files present in the system partition with those located in the downloaded archives.

However, the presence of the corresponding opportunity does not mean that updates will come forever. Typically, device support period is 3 years, and for some manufacturers it is even less.

If Android is “clean”, then you can try to update it through the settings menu. To do this, you need to go to the “About phone” section, select “System update” there and switch the switch to the active position.

Update Android via PC

To update via computer you need:

drivers for mobile devices;
special utility;
archive with update.

Also, before this, you may need to unlock the bootloader, which is done through the developer menu.

connect your phone/tablet via USB to your PC;

run the patcher program;

select the archive with updates;

press the START button (most often it is called that way).

The specific steps that need to be performed in this case depend on the phone model. To obtain the appropriate instructions, you must refer to the manufacturer’s official website or the relevant topics on the forums.

It should be noted that you can install updates from the archive directly from your phone. But this will require the TWRP bootloader.

Update Android using apps

This is the worst way to get updates. Serious companies do not develop such programs, and those applications that exist were created by someone unknown. This method should be used as a last resort.

The principle of working with such applications in most cases is as follows:

downloading and launching the corresponding application;
selecting a device model (if it is not detected automatically);
Click on the Update button and wait for the update process to complete.

The easiest way to install patches on the Green Robot is to run the OTA update utility (OTA utility is a standard application for updates provided by the manufacturer). If Android is “clean”, then you need to go to settings, then select “System”, and then “System update”. If the switch present there is active, then, provided there is a connection to the Network, information about patches that have not yet been downloaded will appear on the screen. To install them, you will need to click on the checkbox and agree to download and install the files.

If the manufacturer has provided its own program for updating the system, then you need to run it and follow the instructions it offers.
If, after opening, it has not loaded information about the packages, you will need to click on the button with the image of an arrow wrapped in a circle. After this, all that remains is to agree to install updates if they were found.

How to update Android on a tablet

How to update Android on a tablet is no different from how to update Android on a phone - these are almost identical devices, just different sizes.

Everything is quite simple, the procedure is as follows:

Download the update and save it on your phone;
Turn off the phone and use the key combination (see the combination on the website of the manufacturer of your device) to go to the engineering menu;
Find the “Apply update” item and indicate the location of the downloaded update - you’re done.

If OTA does not work, then you can update via your computer. For information on how to do this, see the “Via PC” subsection.

Android custom firmware update: where to download, how to install

Attention: It will not be possible to update a custom OS system; a complete reinstallation of the system will be required.

As you already understand, it will not be possible to update the system with custom firmware, and to completely flash the device you will need to obtain RTH rights. Manufacturers mobile phones It is highly discouraged to use custom firmware, much less reflash devices yourself.

In what cases is it not necessary to update Android?

There are several such cases:

The phone already has the latest firmware.
The operation of the device is completely satisfactory and there is no valuable information on the phone.
Your phone is old and will most likely slow down a lot after the update.
You can't connect to wi-fi, and mobile traffic is expensive.

How to disable Android updates

This can be done either by changing the position of the switch in the “About phone” – “System update” menu to inactive, or by disabling the corresponding option in the proprietary application.

How to roll back an Android update to a previous version

In fact, there is no way to do this. However, it is still possible to return to the old system. To do this, you need to reflash the device. But you will need to find the firmware that matches previous version.

You can also reset the firmware to factory firmware, for this:

Find the “Privacy” item in the settings (parameters) menu;
Click the “Reset settings” item in the “Reset settings” tab and wait for the device to restart.

Be sure to do data backup, since after the rollback they will be erased from the device’s memory.

Third-party programs for updating Android

Now we will briefly consider the option of how to update Android on a phone/tablet using special programs.

The first of them is Android Update Manager. Through it you can update Android for free. Its advantage is that it allows you to roll out custom firmware. That is, even if the developer no longer supports the device, through AUM you can install a more recent version of the software on it than provided.

Upgrade for Android Go Next– through this application you can familiarize yourself with the features different versions OS for a specific phone and install them. However, of course, not all devices have new versions.

If you want to update Android as quickly and easily as possible, it is not recommended to use any applications. This is due to the fact that it is far from a fact that the updates will install normally, and if this happens, you will have to remove the phone from the “bricked” state.

As you can see, there are many ways to install updates. However, it is better to use either those provided by the device manufacturer, or popular, proven ones.

Many users try to find on the Internet Android update program phone or tablet, although you don't actually need it. Why you ask? Because all official updates for your gadget come “over the air” (via connected Wi-Fi), or simply via the Internet. 99% of the time, as soon as an update to your version of Android is released, you will see a pop-up message indicating that new updates are available for your operating system.

Official Android update

The advantages of this method are that it is the easiest way to get Latest updates on Android via the Internet. The most important thing is that everything is official, and you can’t go wrong when installing, since there are a huge number of versions and builds of Android. There are several disadvantages to note - if there is no Wi-Fi, you will have to pay for GPRS traffic, and this can sometimes be very expensive and slow.

To get the official update of the operating system you need to go to:

Settings - General - About phone - Software information

U different versions Android menus may be slightly different, but the principle remains the same for all devices. Next, you can go to the Update Center and check for updates, and also check the box "Check for and download updates automatically"

This method is suitable for all users who have not installed other assemblies on their Android.

Android Update Manager - a program for updating Android

Android Update Manager- This free program which you can download and install on your computer. Using this utility you can flash custom firmware at one's own risk! If you have not previously installed updates to the Android operating system manually we do not recommend you to use this method.

The Android operating system is very popular and the reason for this is its many advantages. Many modern smartphones and tablets run on this operating system, which indicates its reliability, otherwise well-known gadget manufacturers would not use Android. In general, this OS has enough advantages, but the purpose of this article is not to describe the advantages and disadvantages of Android. This rather voluminous manual is intended for users who want to know how to update Android.

From time to time, every owner of a smartphone, tablet or other device running on the Android platform needs to update the operating system version. Of course, updating is not mandatory and if this is not done, any device will continue to function normally. However, the old version of the OS often becomes a problem. For example, it may be difficult to install new programs or games whose developers did not take care of later versions of Android. In addition, developers regularly release new versions of the Android OS for a reason. First of all, this is done to eliminate all the shortcomings of previous versions and add new, user-friendly features.

So, we figured out the need to update Android, now let's find out how to update Android on different devices. In this article we will look at using the official and non-official firmware versions. You will be presented with step-by-step instructions on the basis of which you can update Android on your phone and tablet. We will also tell you how to update Android via a computer. So let's get down to business.

Before you update Android, you need to choose the most suitable method for yourself, and there may be several options here. Perhaps the most convenient is automatic updating software directly via phone. That is, this method does not require the use of a computer and pre-download new version firmware, because everything necessary actions will be done in the smartphone settings. This OS update method is suitable for all devices with Android version no later than 4.0. The software update procedure is extremely simple and will take very little time.

It should be noted that the Android update process may vary slightly depending on specific model smartphone. We have prepared step by step instructions using the most common software as an example, but you can easily figure it out if your device has a slightly different interface. So, to update Android on your phone, follow these steps:

1. Go to the “Settings” of your smartphone. This is usually done through the main menu of the phone or using a special button on the phone. It all depends on the model of the gadget. In any case, there will be no problems with this.

2. After entering the phone settings, find the “About phone” item (in some cases, this section may be called “About tablet” or “About smartphone”). Here you will find the build number and android version. After clicking on the “About phone” item, the following window will appear in front of you:

3. Next you need to find and go to the “System Update” section. (in some cases, this section may be called “Software Update” or simply “Update”). Now you need to click on the “Update” button (in some cases this button may be called “Check for updates” or “Check now”). If an update is available for your device, your smartphone will automatically download and install it. In some cases automatic download is not provided and you will need to confirm the software update. If there is no update for your smartphone, you will see a message indicating that you have the latest version of Android OS installed.

Note: Before installing Android, you should make sure that your phone is connected to the Internet and you have enough bandwidth to download new firmware.

It should be said that some devices require certain operating update features Android systems. For example, some Samsung smartphones suggest you need to enable your Samasung account before updating your Android. Please note that we are not talking about a Google account, but about account Samasung. If you have not yet created a Samsung account, then follow these steps:

In your phone settings, find the “Account and synchronization” item and go to it.
Now click on “Add account” and in the window that opens, select the “Samasung Account” section.
Now follow the prompts on your smartphone screen. After activating your account, you can start updating your Android, following the previously given instructions.

Also watch the Android update video on your smartphone.

You already know how to update Android via your phone. Now let's find out how to update Android on your tablet. It should be said that the process of updating software on a tablet computer does not imply significant differences from updating a smartphone, however, there are still some differences, so we decided to prepare separate instructions.

Quite often, tablets are almost constantly connected to the Internet. In this case, the Android update procedure is greatly simplified. The fact is that while in constant network access mode, the device can itself find a new version of the operating system and notify you about it. All you have to do is accept or reject the new software. If a similar offer has already been received, but at that time you decided to refuse it, then there is nothing wrong with that. Just go to the “About Tablet PC” section and select “Update Software”.

If automatic update did not occur, then this procedure can be performed manually. Again, the process of updating Android on a tablet may involve minor differences depending on the specific device model, but the meaning is the same and you will not encounter any difficulties. To update Android on your tablet computer, you need to follow these steps:

Go to “Settings”.
Find "About your tablet." Go to this tab and click on “System Update”.
After this, the tablet will begin searching for the latest software version.
If the device has the latest version of Android installed, the device will tell you that no updates were found. If a new version of Android OS is detected, you will be prompted to install. install. Once the installation is complete, your tablet may restart.

Note: to eliminate problems with the device, before updating Android on your tablet, you need to make sure that the battery charge is tablet computer was more than 50% of the permissible capacity. It is advisable to connect the tablet to a charger when updating the software. This rule is also relevant when updating the OS on your phone.

You can update Android not only directly from the device itself, but also from your computer. To do this, you will need a special program and a disk that comes with the device. You can also download the Android version from the Internet, for example, if there is no corresponding disk or you want to install a specific version.

Today, there are several programs for updating Android, but we use the special Kies application as an example. You can download the program on the Internet, just use the Yandex or Google search. To update Android via your computer, you need to follow these steps:

1. Connect your smartphone or tablet to your computer and launch the Kies application. The program will automatically check if there is a software update available for your device and the result will be notified to you in the appropriate window.

2. If there is a new version of the operating system for your device, then the “Update” button will appear in front of you. Click on it and a new warning window will appear. Carefully study the information provided and only then proceed to the next step.

3. If you agree with everything, check the box next to “I have read all the above information” and click on the “Start update” button. After this, the latest version of the operating system will begin downloading, fully matching your smartphone or tablet model.

4. Once the Android OS files are downloaded, the software update will automatically begin. If the automatic update has not started, a corresponding button should appear, clicking on which you will confirm the start of the software installation.

5. That's all. You have updated Android to the latest version. Now you can evaluate the benefits of the new software.

Android is updated in the same way via Sony programs PC Companion and others.
Also watch the video on how to update Android via Kies.

Many modern gadgets, for example, Nexus, HTC, Samsung, etc. have the opportunity to get Android 5 Lollipop. Meanwhile, often for unknown reasons, many users cannot install this software, since the long-awaited update simply does not arrive. That is, the corresponding section reports that there are no updates available for the device. If you are sure that your smartphone or tablet supports this version of the operating system, but automatic updating does not occur, then you can try to update in another simple and safe way, which, moreover, does not require.

This is a forced update, without the need to manually install the image and use official firmware. Since we did not find a device that does not already have Android 5 Lollipop installed, the screenshots presented in the instructions will already be with this version of the software, but there is no significant difference and the contents of the menu are no different, so you will cope with the task without any problems.

So, go to “Settings” and select “Applications”.

Open the list of all applications. Now you need to find an application called Google Services Framework. Click on it and select the “Erase data” option.

After that, turn off the smartphone and immediately after turning it on, check for software updates again; to do this, follow the following path: “Settings” → “About device” → “System update”.

Note: In some cases, there may be a delay in receiving the update. As a rule, after 10-15 minutes you can start updating.

If your device does not support Android 5 Lollipop, and the previously specified file is deleted, nothing bad will happen. True, for further correct work Google Play You may have to log in again, that is, you just need to enter your login information Google account, rather than re-registering in the system.

You can also watch the video to see how the firmware is updated to Android 5 lolipop.

How to update Android using unofficial firmware

This is where we will end this article. We hope this rather lengthy manual helped you and now you know how to update Android. If you have any problems with the update, ask questions in the comments.

Manually

This method is called “manual” because it involves downloading the update file to the phone through third-party devices. For example, a tablet or PC. And after this, the user launches the package on the smartphone, initiating the process independently. You can update the system version in this way if you have the corresponding file at any time.

Often this method is used in two versions:

the update package did not arrive on the smartphone;
The system is not planned to be updated to the latest version.

The conditions for updating remain the same as for the over-the-air process. With sufficient charge and suitable version The OS procedure will complete quickly enough.

Via PC

Updating the OS using a computer is possible if you have special software from the smartphone manufacturer. For example, samsung kies, Smart switch, Mi PC Suite, etc. Any such software is a tool with file manager functions, so the user can see what the device’s memory is full of and free it up if necessary. In addition, the ability to make a backup, that is, back up the system, restore the OS and update it.

For example, in special software for smartphones of the brand Xiaomi update possible both by searching for OS packages using the program functionality, and independently in file manager, if the version is already present on the phone.

In order to update via PC, you must:

turn on the program;
connect your smartphone to your computer via a USB cable;
wait until the software detects it;
through the built-in functionality, perform the necessary operation - make a backup, restore the OS or update it.

In most cases, if a repair is necessary, you can replace it with an update, since installing the package resets software glitches. But this does not always work, so if there are serious problems, they will need to be fixed first.

Unofficial firmware

Any unofficial OS versions downloaded from third-party resources do not guarantee the correct operation of the device and its software components. Developers who use Android open source to implement their own ideas do not guarantee the correct operation of the final product, and most often do not implement technical support and do not even notify potential users that the system assembly may not interact correctly with the device.

Downloading unofficial firmware is dangerous. Downloading unofficial firmware can not only lead to virus files being added to the phone, but also give scammers access to personal data, including financial data.

Open source code is the source code on which operating systems, applications, etc. are developed. There are companies that do not provide this opportunity, following a closed policy, for example, Apple and its iOS.

Using Recovery Mode

This recovery mode is available on any Android device and is a developer menu that allows you to restore the OS in case of serious problems. software failures. How to install updates if they are available on your phone.

To do this you need:

enter recovery mode using the method for a specific brand and model of smartphone (indicated in the user instructions, can be found in the FAQ on the manufacturer’s website);
select the “Install” or “update/recover from SD card” section (depending on the brand);

confirm the operation.

Before starting this procedure, you must back up the OS and user data.

Using a third-party recovery mode

This option is available through software installed on the user's computer. To start the process, you need to connect your smartphone to your PC, wait until the program recognizes it and click on “Recover” or “Restore”. In some cases, the utility itself will offer to perform an operation if it detects serious software problems on a smartphone.

This option, like Recovery Mode, is used in cases where for some reason the update cannot be done by other means.

When not to update Android

In some cases, upgrading an existing operating system may seriously interfere with its functionality and optimal performance.

When not to update:

the developers did not provide an update package for a specific smartphone model, and the official version did not arrive on the device as a system notification in the settings - this happens in cases where the model is no longer able to meet the OS requirements or the brand has decided to gradually phase it out in favor of new phones ;
the phone is outdated and cannot work correctly on the new OS, it is poorly or completely incompatible with it in terms of hardware and software parameters - this applies to many models that are no longer produced and, accordingly, the manufacturer does not support cooperation with Android developers;
a full-fledged version of the OS has not yet been released, but its beta version for testers has appeared on the network - this is a trial version that will be further developed and adjusted based on error reports sent by specialists around the world, the version is not a user version.

In such cases, the update will lead to numerous failures or complete failure of the phone. It will have to be restored using a backup of the previous system, which in some cases may lead to the loss of personal data and wipe internal memory phone.

In some cases, you may need to do a “rollback”, that is, return to the previous version of the system. This happens if an unofficial package was installed, the performance of the device with the new OS has significantly decreased, or a beta version was delivered that turned out to be too unfinished.

How to return the old OS:

you need to go to the Recovery Mode menu - for each brand and model there is its own combination of buttons, which is usually indicated in the technical documentation, that is, the user manual;
in the menu, click on “update/recover from SD card”, then select “wipe data/factory reset”;

confirm the operation of deleting all user data along with the installed update;

Once the process is completed, select “reboot system now” to restart your phone.

Before this procedure, you must back up and save all valuable user data, since “rollback” to old version The OS provides for their removal.

What to do after the update

After the update, the device is completely ready for use.

Once the process is complete, the device will reboot on its own. You need to wait for it to turn on again and carefully review the updates. They are often described by the developers’ built-in instructions in the form of a presentation. The user is also provided with a complete list of changes made.

This procedure is very simple and quite fast when it comes to system updates sent by the developers themselves. In the event that the smartphone user himself found and downloaded it on the Internet third party package OS, serious problems may arise with the device and its performance. To prevent this from happening, any packages and new versions of the system must be downloaded via system settings phone, that is, from an official source.

The market for smartphones of different brands functions in such a way that as new versions of the Android operating system are released, companies that make phones on this operating system update the OS version on the phones that came out and implement new firmware on those devices that are being developed. Some users don't know why it works this way.

The fact is that when a person buys a phone, it has a basic version of the operating system, it is available by default. But after some time, Google releases a new version of the Android firmware, which improves the old one, removes some bugs, large and small problems. And when some time passes and the new version passes all the necessary checks and becomes stable, you can install it on your phone. The verification time depends on the region and usually takes about six months.

Once the new version becomes available and you install it on your phone, you can get a new interface, support for new applications and more settings. Also get rid of some problems that were in the previous Android series. In some cases, the system update comes to the phone itself and the smartphone is updated without the owner’s participation through the application store, and then notifies you about the new firmware version. But sometimes there are no updates. Then a user who wants to use his phone more conveniently has a question about how to update Android if there are no updates. In this article, we examined in detail how to do this, and also told us how, on the contrary, to roll back the update if you have problems with the new version.

What you need to know before upgrading your system

Remember that if you update the software on your phone, or vice versa, roll back the update to a previous version, the data stored directly on the phone will be lost. In case of automatic update, the phone does backup copy independently and then recovers data from it. If you update or rollback manually, you will have to make a backup yourself.

You can also simply transfer all photos, note data or book numbers to an external drive - it can even be a flash drive in your phone, it doesn’t matter. But it’s better to save it on a computer or external flash drive, it will be safer and more preferable.

Also note that updating the software takes some time. Sometimes it's about 10 minutes, sometimes longer - it all depends on your phone. So before you start updating, make sure your phone is sufficiently charged so that the update won't be interrupted when your phone accidentally turns off due to charging issues.

Automatic Android update

Automatic system updates are the easiest thing you can do. To do this, you don't need to do practically anything. You just need to go to the Android menu and select “Phone Information”, here you will find out what firmware version is on your phone.

After that, in the settings you should find “Software Update”; on all phones this item may be located in different sections of the settings. If you have a settings search, use it; if not, search manually using the settings. When you open this tab, you need to select the update icon and confirm your action. Before you start updating, enable download new system only via Wi-Fi so that the system does not waste Mobile Internet and your money.

When the data for the update is downloaded from the company’s server, a menu should appear on your phone and click “Install” there, after which you need to wait until the update takes place and the phone reboots.

Please note that in the method we described above, you can only update your phone to the minor release build. So in order to get a good full version of the firmware, you need to use a special mini-program that is released separately by the manufacturer. For example, for phones and Samsung tablets this is Kies, and for LG equipment - PC Suite. Google what utility your manufacturer has, install it on your phone and update through it.

Manually updating Android firmware

Almost all service centers They use the manual method of updating the system if a client comes to them complaining about a program malfunction. But you can update your phone manually yourself if you put in enough effort and perseverance.

In order to update operating system on your phone, you need to work with system application Odin. It can be downloaded to your computer from various web resources, it is even available on the well-known w3bsit3-dns.com. With this application you will be able to install not only a custom version of the firmware, but also the official one. In order to complete the update, you need:

If everything has been updated and went as it should, without any glitches, then the program screen should display the message PASS, which will turn green.

These methods work if you want to update Android 4.2.2 or any other firmware version. The main thing is to download the correct archive and make a backup copy of the data before proceeding with the update.

Rollback to previous version

Imagine that you performed an automatic or manual update to a new firmware version of your smartphone, but you didn’t like the way the phone now works. It may have become much slower, often reboots or freezes, and errors appear. In this case, you can simply “roll back the phone” to any firmware version that was previously installed on the smartphone.

Rollback to factory version

This method is suitable for you if you want to return the basic official factory firmware, which was installed on the phone at the time you bought it in the store. This is done simply, in a few clicks from your phone.

You need to go to the “Settings” section on your smartphone and select the tab there that is responsible for resetting the settings. Each phone has a different name, some have it under the “Privacy” button, some have it labeled “Backup and reset”. If you can’t find it on your phone, google it; if your smartphone didn’t come out less than a few months ago, then this information should already be on forums or in articles analyzing the settings of your model.

After you have found this section, you need to select “Reset settings”. A window should pop up warning you that all data from the phone will be permanently deleted. If you have saved all important data in backup copies in the cloud or on external media, then confirm the action.

Note! If you think that your phone itself saved backup copies in the cloud, but you can’t be sure about it because you are updating for the first time, it’s better to save them yourself on an external storage device, just in case, than to grieve about lost important numbers, documents, etc. photo.

After this, the phone should reboot and roll back to the factory version. The reboot may take a long time - up to 15 minutes, don’t worry. After the phone turns on again, it will already have a completely clean system, as if you had just bought it in the store.

Heavy reset

This method involves completely manually restoring the phone to the old firmware version. This method is suitable for you if the phone does not boot at all or if you need to reset the PIN code, graphic key or password in case you have forgotten them. During this update, you will also lose everything on your device, so make sure you back everything up.

The rollback process goes like this:

Turn off your phone or tablet on which you want to roll back the firmware version.
You need to simultaneously press and hold the button that increases the volume, the home button, and the power button. The Recovery menu should appear on your screen.
When controlling your actions using the buttons that adjust the volume, you need to find and check the “wipe data/factory reset” item and confirm your choice.
“Yes – Delete all user data”, this is also done using the keys that adjust the volume on the smartphone.
After this, you need to press the power button again, the main menu should pop up. In it we mark “reboot system now”.
After that, everything is ready and you should load the factory version of the phone firmware.

How to rollback if a custom version of Android is installed

If you installed a custom version of the new firmware on your phone, you can return the official version that you had before using a manual update. To do this, you will again have to use the Odin program, which we talked about above.

Before rolling back, you need to look for an archive with a firmware file that is suitable for your phone model.
