Hi, I have a elite model with a lite on drive, it was already flashed by a guy who has a shop who unfortunately did not make a back up of the drive key, then my brother updated it thru usb without reverting back to stock now it cannot play back up games, but originals still works fine. Is there a way to extract the key, then flash it to lt 3.0? will probe 3 work with the latest JF? or do i have to do a MRA hack?
