First, we will introduce how to enter recovery.
1: completely shut down. Press and hold down the volume + power key to start the boot, and enter the bootloader interface.
2: press the volume key to move the cursor to the recovery line.
3: press the power button (the machine will restart to enter recovery)
The volume key is the Cursor Selection key, which can be used to move the cursor. the power key is the confirmation key!

I. Recovery Main Interface
Bytes ------------------------------------------------------------------------------------------------------------------------------
* Reboot system now: restart the mobile phone (select this option to restart the system)
* Apply sdcard: update.zip: Install the update.zipupgrade package in the storage card (you can name the brush package as update.zip and then use this option to directly upgrade it)
* Wipe data/factory reset: CLEAR user data and restore factory settings (required before flashing)
* Wipe cache partition: clears the system cache (executed before flash) (this option can also be tried if a system problem occurs, which can be solved in general)
* Install zip from sdcard: Install the zip upgrade package from sdcard (you can execute a zip upgrade package with any name without specifying the name of the upgrade package)
* Backup and Restore: backs up and restores the system (the function and principle is like chost one-click Backup and restoration on the computer)
* Mounts and storage: Mount and storage options (for detailed functions, see the following description)
* Advanced: Advanced Settings

* Report error: Error Report (used in conjunction with the firmware manager, not ignored by developers)
* Key test: key test (basically unavailable !)
