ipad error 40 - GSM-Forum

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

error* 40* the error is caused by hard disk or the Power output of nandflash
