Initially, the functionality of tablets or smartphonesfor users is severely limited. They often can not install some programs, change the boot animation, delete unnecessary embedded applications. There are even gadgets with built-in advertising in the shell itself. To be able to change this (remove / install the program, change the animation), you must have root-rights. It is they who open the administrator functionality for the user.
They do not need a normal person at all.Built-in user functionality is more than enough for full use of a smartphone or tablet. With root-rights you can change the system settings, which are difficult to understand.
Therefore, software developers initially endowuser with ordinary rights. And this is done for security reasons. Without root-rights, no virus can do much harm to the user (steal his money, show third-party advertising, etc.). But if the user has root-rights, they will automatically receive third-party programs, including viruses.
When a user studies the possibility of changingit's necessary to get root-rights. Consequently, he often encounters the term "TWRP firmware". This is a powerful system recovery utility that provides the user with much more features than the standard.
TWRP Recovery allows you to make full backupscopies with the ability to select the necessary items to save, more flexible to configure different options, use S-Pen on Galaxy Note devices, install non-standard programs, firmware. And this is not the whole list of possibilities. There are more, but it is possible to list everything, including petty ones, for a long time.
The installation process itself does not require special knowledge andeffort, takes little time. There are even special wired programs on Android-devices for modified recovery, so installing TWRP will not be difficult even for a not very confident user. For example, in the Nexus tablets there is a Toolkit application, where recovery recovery functionality is available. But also on the Google Play service there is a GooManager program - it can be installed on any Android gadget. It has the "Install OpenRecovery Script" function.
To start (or rather get) into TWRP Recovery, you can use different methods:
After launching the recovery, the following buttons (functions) will be available:
These are the main points in the interface. Now let's see what it all means in TWRP.
Install - is used to install patches,various modifications and new firmware. This is the most commonly used function. It is mainly used for installing official and unofficial firmware, changing the skin theme, etc.
Wipe is a menu for deleting files and cleaningsystem. The functions here are practically unlimited. That is, you can clear any part of the memory, but you can completely erase everything and return to the factory settings. You can clean the folder, flash drive, internal memory.
Backup. Section for creating backup copies of the system. Of course, this is one of the most important items in the recovery. The feature allows you to make a full backup, including application data.
Restore.After the backup process is completed, you can restore the previously created copy in the Restore menu. And, you can restore the copy from the internal memory of the device or flash drive (as well as save Backup to a flash drive or gadget memory). When a backup is detected, the user will be asked to mark the partitions that need to be restored. You can also delete a copy, rename it, etc.
Mount.In this menu, the functions for mounting and deleting partitions are available. You can also perform operations with them. The functions of mounting and unmounting the system partition of the cache, internal memory, memory card, data partition are available.
Settings. Here are the settings for TWRP.What does it give? At a minimum, you can enable / disable checks for subscriptions and checksums for different files, do not take into account file size errors during backup, etc.
Advanced. Additional functions that allow you to save log files to an external memory card, change partitions on a flash drive, return normal access rights to applications with root privileges.
Reboot. There are only 3 functions here: disconnect the device, reboot with an exit to the system, reboot with the output to TWRP. What is Reboot, intuitively clear to all.
Working with these menu items is easy. For example, to install any firmware or patch in .zip format it is necessary:
It is acceptable to select 10 files at once in the .zip archive. All of them will be installed sequentially. After the process is completed, it is desirable to clear the cache.
Now you know that this is TWRP, and how toto enjoy. But without the need for this functional it is better not to indulge. It's no accident that after all, the developers left the user with the usual rights and reliably hid the root. Leave this functionality to people who understand. After all, because of ignorance, you risk returning the phone to factory settings, for example, and then you can not restore important files without backup.
