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.

RPi 4B 8G, Raspberry OS up to date, x735 v2.5.

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