The system will power off now!

Doing steps according the manual. Then the OS isn't booting, just shows the logo, then powers off again. Only deleting the /lib/systemd/system/x735-pwr.service file from the microsd card makes the OS bootable again.

P.S. Please, translate Chinese to English in the repo files.
