To resume brushing, the steps are as follows:
1) Brush the rom of the corresponding mobile phone downloaded from the Internet, and then copy it to the root directory of the SD card. Rom is in zip format (you can open it to verify it. 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 phone from the computer.
6) Shut down completely (it is best to dig the battery after shutdown), and then enter the recovery interface through special key combination.

3.) Select item 5 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 brush files and press the power button to confirm, and then select Yes to start brushing.
5) After brushing, that is, after brushing the progress bar of the interface, 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 the end of the brush.
