Just download factory image pack,reboot your device to fastboot and connect to computer.

Open flash program(flash-all.bat),it will flash automatically.But first,you should make sure your bootloader have fully unlocked.

If not,when u flash,the program window will say "unsupported command",if you have original recovery, you can try lock bootloader again and unlock it.

For some reason,this solution can make it turn into full unlock,then you can trying flash factory image.

请问您怎样 fully unlocked了，我看前面你也是unsupported command

Mod translation: May I ask how you are fully unlocked, I see that you are also unsupported command

你重新上锁然后解锁好像是会解锁到完整的，但是前提是你确定机器里面还有rec，如果还是不行考虑换线换设备，我也是我寝室尝试了三台电脑就一台能正常刷

Mod translation: If you re-lock and unlock it, it seems that it will be fully unlocked, but the premise is that you are sure that there is rec in the machine. If it still doesn’t work, consider changing the cable and changing the device. I also tried three computers in my dormitory, and one can flash normally.
