In this case, rationally roll back the firmware, I mean return the old version.
Why return the old firmware version?
In the theory, the refund of the old update seems absurd and unnecessary. In practice, often a new version of software brings a lot of problems and flaws: Wi-Fi is turned on without reason, for example, labels, programs from the main screen disappear.
Also, the smartphone can be strongly "hanging", do not play video, ignore some utilities. There may be weight such troubles, and return to the last version of the update will help get rid of them.
How to roll back the firmware on Android: several proven methods
There are several effective methods to return the old firmware. Some of them imply preliminary training, others will be able to help when you need to immediately return everything back.

The literal translation of this procedure "return back" completely characterizes it. This method is only suitable if the backup has previously been made. Then the user will be able to return to the old version of software, restore applications, programs and settings at the time when the last backup has been made.
The user must take into habit of doing such copies. They can save from the sudden disappearance of important information, data loss and malfunction in the work of technology. If this was not done in advance, you can find a backup on the Internet. It must fully correspond to the device for which it will be used.

In order to accomplish a backup, you should download a special application. There are a lot of them. One of the most reliable and popular - Titanium Backup. The program will allow you to quickly create a backup copy and recreate the last mode of operation of the device.
Work on the firmware rollback in this way begins with the fact that you need to download the program and have root - rights. The latter are needed to access system folders and files. This is very important because they store the desired settings, important information.

The algorithm for creating a backup using Titanium Backup will be:
- On the main screen to select "Backup Copies".
- "Processing" - "Make a backup of software and system data."
- Then choose "Start".
- All applications will appear on the screen to be copied.
- Confirm the process.
After that, the backup will be launched. The procedure can delay due to a large number of applications. What will the user sees after the end of the process:

- in the program menu, select "Processing" - "Restore" - "Restore all software" (then all settings and applications are restored);
- in the Backup Copies tab, select the desired files and click "Restore", then you can selectively recreate the data.
After the proceeded, restart the device, and the changes will take effect.
Reset and hard reset
You can refuse the latest version of the device using data reset to factory settings. The minus of this method - all the developments will disappear, the device will begin its "life" with a clean sheet.
To do this, you need to enter the smartphone or tablet menu and select "Settings" - "Restore and Reset" (or "Device Memory"), and after - "Reset to factory settings".
Hard reset is performed using a key combination. These combinations may differ depending on the device model. Standard diagram - Turn off the technique and simultaneously press the inclusion key and decrease the volume.
If this combination does not help, then you need to look needed for a specific gadget on the network.
After pressing the combination, the settings will begin, and the automatic reboot will occur.
Recovery.
Another application that allows you to roll back the firmware on android devices. At the same time it is necessary to have a downloaded file with the firmware.
First you need to download and install the program. Run it. Next, you should adhere to such an algorithm:
- click on "WIPE DATA";
- next - "Installing an archive from a memory card" - "Select an archive for installation";
- find a file with firmware and click on it;
- confirm the action to start the process.
