Many smartphone owners are wondering: "How to update the Android operating system?". But there is another category of users. They tend to roll back the update. Thoughts about this arise after you understand that the device after receiving new version The firmware is extremely unstable. So I want to get back the old version of the operating system. Below you can read about how the system is rolled back.
Modern electronic gadgets are very much dependent on software. In many cases, the device is sharpened for a specific version. operating system. For example, if a laptop was sold with pre-installed Windows 8, then with a high degree of probability it will not be put on the “seven”, unless you replace HDD. The situation is similar in the case of Android-based smartphones. Only in some cases can you cope with installing a very old version of the operating system if the device came with Android 5.0 or 6.0.
Not all users know about this, but even mobile components work with the help of drivers - in this regard, they do not differ from PC components. For the sake of economy, processor manufacturers write drivers only for specific versions of the operating system. So it turns out that some Snapdragon 820 is simply not recognized by the old Android 4.2.
However, a rollback implies installing the version of the OS that was previously installed on the device. And manufacturers, it would seem, should not interfere with this. But not everything is so simple. It would be easy to rollback the system only if a copy of it would be stored in the device's memory. But Android devices do not have such a function - the update completely erases all data about the old version of the operating system. This is due to the fact that there is not a lot of built-in memory in smartphones and tablets, no one wants to occupy it with an extra load. That is why it is very difficult to make a rollback to Android, it is better for an unprepared user not to do this.
Differences from the update
If you have updated Android at least once, you should be aware that this does not delete the user's personal data. Photos, applications, music and everything else remain in place. But if you decide to roll back Android, then it will equal reset to factory settings. All information will be deleted.
Another point is the difficulty of rollback. To update the operating system, you often do not need to do anything. The new version comes over the air, after which you just need to click on the "Download" and "Agree" buttons. For rollback, there is no universal guide. You will have to get a special program, install it on your computer, download a custom recovery menu and do many other things. That is why it is recommended to roll back to the previous version of the system only in case of urgent need.
Rollback on devices from ASUS
So, it's time to talk about how to roll back Android to a previous version. On many devices, this takes a very long time. But there are also exceptions. Old tablets and smartphones from ASUS require the following steps to rollback:
Step 1. Download the firmware you need, suitable for the model you have. You can find it on the official website or other resources dedicated to mobile technology.
Step 2 The downloaded file should be uploaded to the root directory of the device.
Step 4 After scanning, a triangle should appear on the panel near the clock and Exclamation point. Click on this icon.
Step 5 Agree with the proposed procedure.
After that, the flashing procedure will begin. Interestingly, it does not matter to the system which version of the firmware you have uploaded. This means that in this way you can not only roll back, but also update.
Devices from other manufacturers
To perform a rollback, you will first need to prepare your device.
- First of all, it is necessary get root rights. This will give you access to all system files, as a result, you can perform any actions with them.
- Next, you must download the appropriate firmware to your computer. To do this, you will have to visit the relevant sites where fans of flashing smartphones and tablets sit.
- You also need to remember to install the drivers on the PC. Without them, it is impossible to get from the computer full access to file system smartphone.
- You also need to download a special flash driver. It also differs depending on the manufacturer of the device, so we cannot recommend anything specific.
- Finally, you may need to install a custom Recovery. But if you have found a suitable program and got root access, then you can reflash your smartphone without going to the Recovery menu.
This should be your preparation. Then you just have to connect the device to the computer using a USB cable, run the program and follow the instructions from its creators. In a word, this is how you flash the firmware, which is essentially the rollback of the update.
Often the best way Restore Android is a factory reset. This way you can solve most problems with the device freezing and various glitches. If the gadget turns on and is able to boot on its own, then the easiest way to clean the system is to initial state with the removal of all user data - through the settings menu.
We carry out a Hard Reset from a running system
This feature is already initially included in the interface of any Android device, so no third-party utilities to perform a full reset of the device, if it turns on, you will not need:
- Go to the device settings, sometimes the folder is called "Settings";
- Here, go to the section for archiving data and resetting settings;
- Check that the data archiving and auto-recovery items are checked, then you can easily restore the current settings of the gadget after it resets the settings;
- In "Personal data", click on the data reset line.
After that, it remains only to read the system warning that all installed applications and the user account will be deleted from the device's memory. Confirm your intention, after which the gadget will reboot and you will have an absolutely “clean” smartphone or Android tablet in your hands. It will be cleared of all personal information and malicious applications.
You can also restore the factory settings to the android device using a computer using the proprietary program of the gadget manufacturer. You just need to connect it to a PC, find the "Restore" item and start the process, following the instructions of the program.
Entering the recovery menu
Just like in any system, you can carry out the data reset procedure, the capabilities of the Recovery console are embedded in any android device, even if it does not turn on. The only difference for gadgets different manufacturers- implementation of the procedure for entering this mode. Let us present an approximate algorithm of actions for entering recovery mode, and also describe how he can restore the system.
For Samsung devices:
- simultaneously hold down the volume down and Power buttons;
- after the logo appears, release the power button while still holding Volume Down until the list of Recovery Mode commands appears on the display.
If the algorithm described above does not work, then simply hold down three buttons at the same time - Power, Volume Up and Home until you enter the reset mode.
Please note that the device must be disconnected from USB and from charging, so it is better to recharge your device before carrying out the hard reset procedure.
- pinch power buttons and the volume rocker in the middle for a few seconds;
- then once - on Volume Down or Volume Up.
If the method does not work, press Power until the device vibrates, then press Volume Up several times at once.
For Nexus devices, ASUS, etc., the method of pressing the Power and Volume Down keys at the same time is usually suitable.
Recovery Mode Features
It provides the user with several options at once, even if the tablet does not turn on. The most accessible for any user - full reset settings and delete all user files. In this way, you can solve problems with the unstable operation of the gadget, for example, as a result of a virus:
- Using the volume rocker, select the menu item wipe data / factory reset;
- Activate this function by pressing Power;
- After the reset is completed, which usually takes no more than a few seconds, activate the Reboot System Now command in the same way.
The device will reboot, and it will fully restore functionality. True, user applications, files and settings will be deleted. Therefore, if the device turns on, make a backup of it.
Making a backup from the recovery console
In order to be able to restore its functionality after resetting the device, it will be useful to make a full backup of the device. It is enabled in the Recovery console:
- Using the volume rockers and the Power button, select and activate the Backup and Restore line.
- In the menu that opens, open the Backup item in the same way.
The process of creating an archive takes about 10 minutes. To restore the system from the created archive, select the Restore item in the Backup and Restore section. But keep in mind that a full system backup can be done in this way only if you have Root rights.
Android recovery without root access
Few ordinary users want to solve problems with getting Root access to their device. Therefore, let's consider the Safe Backup application, with which you can back up various data if the smartphone / tablet turns on - contacts, alarm clocks, calendars, bookmarks, photos, videos, application installation archives, etc.
Every year, Google releases a fresh version of its own operating system for mobile devices - Android. It is the most common and overtakes its direct competitor from Apple - 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 lovers of "apple" devices. But sometimes there are situations when it becomes necessary to roll back to more old version firmware. This is especially true in cases where the user did not initially uncheck the box in the settings item. automatic update systems. But not everyone knows how to return old firmware on Android.
Need for updates
Before talking about how to return the old firmware to Android, it should be mentioned 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:
- correction of identified bugs in the system;
- reduction in power consumption (Android with each new update becomes less energy-intensive, which allows you to get more time battery life without increasing the battery capacity);
- resolution of problems in the operation of the hardware (this includes the camera, sound, multimedia capabilities).
But not every user is happy with innovations. Some after the next update dream of returning the old version of the firmware.
This may be due to a violation of the stable operation of the device, especially if a new version of the system is released, which does not run on all supported devices in full. Innovations may also include the addition of services that cannot be removed.
It should be noted right away that when deciding how to restore the old firmware on Android, it must be borne in mind that, unlike, for example, Windows, the default rollback function is not provided on a smartphone or tablet. Therefore, when returning to old version The OS should be prepared for the loss of all data.
How to restore the old firmware on Android using a factory reset
The easiest way to "demolish" the received system update is to roll back to the factory settings. After carrying out these manipulations, the user receives a phone that, in terms of its internal content, will be similar to a freshly purchased one.
To roll back in this way, you need to go to the desired menu item:

The second way to roll back to an earlier firmware version is to use the regular Recovery menu. To access these settings hidden from an inexperienced user, you need to press a certain key combination.
The most commonly used is the simultaneous pressing of the power button and the volume key (up or down). Some devices use a triple click with the addition of a Camera button.
After getting into recovery mode required:
After that, the device will start rebooting, as a result of which the user will receive “ new phone from the box".
Flashing the device
Another way to return the old version on Android is to flash the smartphone. To do this, you first need to download required version software. This can be done on specialized forums. After downloading, you need to upload the archive to a memory card, since it is from it that the firmware process will be carried out.
A factory reset deletes all data from your phone's internal memory. These are photos, videos, music, applications - everything that was recorded during use mobile device. In this case, the sd-card will remain untouched: the files on it will be saved after hard reset.

On the phone (samsung a5) the glass was replaced and the phone was reset, photos and videos disappeared. Is it possible to recover and how? Tried through your program - it did not work.
Answer. Curious to know what recovery programs you used. The question also arises, where did you look for the deleted data - in the internal memory or on the sd card. As it was written above, a factory reset erases internal memory, so you will need utilities like DiskDigger for Android. Another recovery method is through creating a snapshot of internal memory and then searching for files on it.
Android 5.1 Lenovo A2010. I wanted to update, but I clicked on the factory settings and all the necessary photos and videos disappeared. Downloaded, but it is impossible to open, i.e. does not open on the phone. What should I do to recover deleted photos and videos?
Answer. Really. Tenorshare Data Recovery can only be run from a computer. It is not a fact that with its help you will be able to return data after a hard reset (that is, reset to factory settings). You need a way to recover from internal memory. See answers above where we answered a similar question.
I made a hard reset on the lg D724 phone, after synchronizing everything. But I missed the most important thing - notes from the notepad application. The wife had a lot important information in notepad. Can you please tell me how to restore it?
Answer. Try . We have not tested, but the developers claim that MobiSaver can recover notes. However, it is important to note that after a hard reset, the internal memory is erased, and not all applications can work with it. So, to be honest, there is very little chance of getting back text notes after a reset.
I have samsung galaxy s7 edge. The problem is that when I entered the camera, she gave me such a notification "Camera error warning", after which every time I enter the camera the phone gives such an error. I reset the phone to factory settings, but it did not help ... clearing the cache in the camera settings and reset her data, but all my efforts were even, nothing helped.I went to the service center, they said that they did not have the equipment to disassemble and see what was wrong with the phone, and in return they could send it to Moscow for repair, but it will take weeks or more I don't need it.Is it possible that if I roll back the phone to the previous version of the OS, that is, to 6.0, since I have 7.0.Or just reflash the phone.Tell me if this helps?If not, then help and tell me a couple of ways to fix this error.
Answer. Log in and check if the camera is working. This will help identify whether additional applications, installed by you or together with the firmware, to the camera.
Perhaps you are using custom firmware - if so, we advise you to find alternative versions or flash your phone to the official firmware.
If resetting to factory settings really did not help, you need to contact service center Samsung or, as you mentioned, send it to Moscow for repair.
Phone reset to factory settings, how to recover data from phone? Tried through applications from Google Play, almost all of them require root. What is it and how to get it?
Answer. Root access (or superuser rights) gives recovery programs access to the file system android full control, including deleting and overwriting files. Although, in fact, recovery programs only need access in read mode.
Even if you find an application that does not require root, the chances of recovery will be extremely small. Try installing KingoRoot apps ( root installation in a few steps) and DiskDigger for Android should work.
After reset Prestigio settings NK3, the system writes that the sd card is not supported and offers to format it. The reset was carried out with the card removed. There is a lot of necessary data, tell me if there is a solution?
Answer. Most likely, hard reset in no way affected the safety of data on the memory card. If you removed the memory card while other files were being written to it from the phone, the file table of the sd card could be damaged. You need to connect it to a computer or laptop through a card reader, check for errors in reading the standard Windows utility. If the bugs are fixed, the sd card should open on the phone. If not - Recuva program or DiskDigger with Dig Deep mode should find all files.
Wife made a hard reset on the phone Samsung Grand 2 Duo without making a backup copy. Photos and music are not so important, all phone contacts were lost and it was not possible to restore application data from Play market. In all applications, everything had to start over. Can you please tell me how to restore it?
Answer. The likelihood of recovering user data from applications depends on each application individually. So, if the user data was stored on the sd card, then you can recover the data. Otherwise, after a hard reset, you need to scan internal memory trying to find each separate file applications (the probability of doing this is quite small).
Phone contacts can be imported from a SIM card - of course, if you take care of backup contacts in advance. Check if the contacts have been synced with your account Google and its assigned Contacts service.
Despite the fact that developers strive for the ideal, a new update to a familiar application does not always bring pleasure to the user. It's more of a matter of habit though. However, many people want to leave the application as it was before the changes and are looking for information about how.
It is worth noting that VKontakte in the fall of 2017 completely updated its mobile app. This is one of the most tangible changes that the program's interface has undergone in recent times, before that a similar upgrade was presented by the developers in April last year. Almost everything has changed, from new user features to the overall organization of the workspace. And even "likes" are now red.
Despite the fact that the optimization is pretty good and the application itself has become more convenient, many (as, indeed, last time) want to continue using the old, more familiar version.
All Android users are well aware of the service for downloading and installing new PlayMarket applications. Depending on the settings set in this application, the programs installed on the user's device will be updated in two available modes:
- Manual - when PlayMarket simply offers and recommends available updates, and the owner of the gadget independently decides which one to install and which one to ignore.
- Automatic - as soon as a new update appears in the Device Market, the installed program automatically accepts it and updates it. In this case, the user enters the application and sees new design and interface (as it happens with VKontakte).
In this connection, the first action that an adherent of the old VKontakte software should do is to turn off auto-updates of applications and switch it to manual mode.
To do this, go to the PlayMarket application menu, to do this, click on the "sandwich" in the upper left corner, in the menu that appears, go down and find the "Settings" section. In a group general settings we find the item "auto-update applications" and select the three proposed settings options "Never". 
At this point, the settings are complete. This was the first step in resolving the issuehow to return the old version of VK to android.Now PlayMarket will not automatically update installed programs, and the user will be able to safely use the old-style program without fear of autocorrect. If you need to get a new version of the program, just go to the installed applications section yourself and check for updates, and also, if necessary, start the upgrade.
After external settings that affect the version update are installed, you can start working with the program on the device itself.if Market doesn't automatically update apps anymore? In this case, everything is quite simple, the process is divided into two steps, which involve uninstalling the updated program and installing the desired version.
Uninstalling the updated app
This step is extremely simple and straightforward, you just need to completely remove the existing . If you are an inexperienced user and you are worried that you will lose information or access to your account, then these are groundless fears. The old version will contain everything that is on your page now, it does not depend on the use of the software.
Delete installed application can be done in several ways:
After the updated version, you can additionally clear the cache and delete unnecessary files on the phone. The procedure is not required, but it will not become superfluous.
Installing the correct version
After the smartphone's memory has been cleared of the remnants of the previous version of the program, it is time to take the final step in resolving the issue,how to return the old version of VK to Android.
The main question of this stage is where to get the distribution kit of the previous version of VK. Today on the Internet you can find a lot of offers to download and install any program, and not just VKontakte. Before turning to any source, you should first check its reliability. Software installation for mobile access to a personal VK page from a third-party resource can be fraught with unpleasant consequences, and VKontakte itself previous versions does not distribute applications.
Before you download a package of files and install them on your phone, you should look for reviews about the source. Today, old versions of VK can be found on TrashBox or UpToDown.
Before downloading the distribution kit, you need to set the settings on the gadget. To provide greater security, devices are set by default to prevent downloading and installing applications from third-party resources. To install an older version, you need to change these settings. Usually when trying to install desired program a pop-up window pops up. A warning about unauthorized actions and a suggestion to deny or allow the process.
