11 error 9 , error 40
Hi , i have an ipad 4 which suddenly showed the apple logo during normal use . when i tried to update / restore i got error 9 , i tried a new lightning port , new battery , tried a restore with reiboot pro . also tried another pc and a macbook for the restore …
I removed the board and used naviplus pro to read the nand chip , seems ok , i also repaired the nand with naviplus and tried to restore again , now i get error 40 . , i’m thinking now may be cpu , is there a test to confirm this ?
..here is a link to the itunes restore log
Es esta una buena pregunta?
