@SteeMan Firmware on my android box is for MXQ 4k 5g, older original version, and I can send you if you want the .img file of the firmware.The CPU of my android box is sun8iw7 Allwinner.When I power OFF the box I can't power on it anymore.

Hey @eselarm, Thanks for the quick answer. My goal is indeed having a more generic computer for server tasks. The version of the u-boot is: I have switched again to the orangepi5 6.18.10-current-rockchip64 kernel but still not showing nothing. Thank you.
