iPad Pro 12.9 Fix Error 9, 14, 4013 NAND Repair

HOW TO FIX IPAD PRO 12.9 ERROR 9, 14, 4013?

Today we have received iPad Pro 12.9 form London and it was stucked on iTunes logo and And it was giving different error 9, 14, 4013 in iTunes. so based on our previous experience we knew that this issue related to the NAND memory IC chip so we have to repair it or replace it with another NAND memory IC chip.

first, we have  removed  the logic board And then desolder the NAND and  put it in our programmer To program it and after that, we reballed it and install it on the logic board and solder it on the logic board and tried to restore it but still we were getting error 9 or 4013 or 14 so in this case we have to replace the nand and we have copied all the information from the damaged nand ic and rewrite it on the new NAND and soldered it on logic board.

and this time iPad pro completely has restored by iTunes without any error and iPad pro started working again.
