Hey guys, I don't know if this has already been posted or not. I acquired a slim xbox with dash 12xxx and a Lite-On slim with stock 9504 on it. I backed up the original firmware on the drive bc I know the drive will get updated to 0272 and get locked. My question is, how do I go about updating and then flashing the slim Lite-On with the firmware? If it gets locked with 0272 firmware how do I unlock it?
