I can revert it to 4xR and 7xR whatever i want to.
Dont try to reupgrade your boot to 0A.02 when there are still boot 07.D0 and E398@Rokr MP based, it'll stuck in ERROR;0x500, after that you mvst do testpoint. In my opinion, flashing boot oa.o2 may still be possible if we can erase boot 07 and MP inside the phone first, but no one maybe dont have the bootloader file and the start address of this boot. Its OTP memory, like locking the disc, may be yes? may be no.
