Hi, i’m installing android q using the guide from radxa, so far, i’ve been able to boot from nvme using the SPI without problems, but i wasn’t able to gain root (besides the adb access). I’ve dumped the boot partition using dd and patching it with magisk, but i can’t write it vía fastboot because the bootloader seems to be locked, and there’s no OEM unlock option in developer options. I’ve already tried booting with linux, and overwriting the partition with dd, but then the 4C won’t boot again, i must be missing something about GPT partitions. fastboot oem unlock, fastboot flashing unlock, and fastboot flashing critical_unlock won’t work here. I’m trying to make an upgradeable car head unit, but i’d like to unlock root to allow further modification. Making it short, does anyone know how to root this thing? Or i must build the sources from the ground up?
