iPhone X after swap full board stuck in recovery mode

[parvizhamidi]

Hi,


I swapped an iPhone X AP and BB boards and after that device stuck on recovery mode.


what I did:

1.Exit from recovery by 3utools without any success.
2.Checked all AP's and BB's board diode mode is ok.
3.Checked all component specially resistors near Nand and CPU.
4.Checked all voltages of PMU all is ok.
5.Checked BB board with other AP board in ok condition that phone powered on without any problem it means BB board is ok and problem is in AP board.
6.Changed U6300 (Hydra IC).
7.Restore iPhone by iTunes without any error


Is there any solution to solve this problem?


Thanks in advanced.

Hi,

Thanks for reply, I did not use read and write method. I swapped EEPROM too.
