for some reason i keep getting a e66 error while trying to update to the newest dashboard which i read up on and it says its because the drive is modded with custom firmware which i have no idea if it is or not but i tried getting the key off my samsung ms25 and it keeps failing to put the drive into vendor mode when i click on sammy unlock i tried it with the tray half opened and with the tray closed but it keeps failing in putting the drive into vendor mode i bought this xbox off someone which it red ringed and i successfully reflowed the console any ideas?
