        The new serial number is for an MBA 13" 2013 so there's probably a mistake there.
        Also 820-5482 is the RIO board number, the MLB should be 820-00138.

          Hi , maybee the reason of bootloop issue is the battery status.

          the battery was totally decharged, i try to charge it a while and test it again.

          i will repost when i test it again.

          regards
