Double-clear (double-wipe) if you can enter recovery, and brush the machine if you can't restart after double-clear; You can't "store bricks" on Baidu.
How to enter recovery mode:
Method 1: When the mobile phone is turned on, please turn it off first, take out the battery and then install it. In the case of shutdown, press and hold the power key +Home key at the same time until the recovery interface appears.
Method 2: If none of the above methods can be accessed, then turn it on again, first press and hold the Volume+key, and then press and hold the power-on key for a long time until the recovery interface appears.
Resume the brush machine (the power key is confirmed and the volume moves up and down), as follows:
1. Brush the rom of the corresponding mobile phone downloaded from the Internet and copy it to the root directory of the SD card. Rom is in zip format (verification can be turned on. Only files with META-INF in the zip package are brush packages, but don't change the files in the zip package) and don't decompress them. After copying, you can disconnect the sd card from the computer.
2. Shut down completely (it is best to dig the battery after shutdown), and then enter the recovery interface through a special key combination.
3. Select the erase cache partition and press the power button to confirm, then press OK and select Yes; Then select Erase Data/Restore Factory Settings and press OK. Select Yes and confirm. (If it's just double clearing, stop here. )
4. Select to install zip from sdcard and press the power button to confirm, then select zip from sdcard and press the power button to confirm, then select rom to refresh files, press the power button to confirm, and then select Yes to press the power button to confirm to start refreshing.
5. Finish brushing, that is, the interface after the progress bar is brushed, and return to the restored main interface. At this point, choose to restart the system immediately and press the power button to restart the phone. It takes a long time to restart for the first time, be patient! This is what happens when you brush your computer.
