DFU reboot and invalid serial error (i7P)

텍스트:

Hi Community,

Got a phone given to me of a repairer. Original repairer killed the phone after a screen replacement. I have managed to get power to return to the device after a tristar change, however, the phone now boot loops into DFU mode.

I have attempted restore via itunes and it returns an error similar to "cannot find device" and using 3U which returns two errors:

* "Unable to switch DFU mode to recovery mode" however phone goes into recovery mode, so i try flash again and get the next error
* "Invalid serial number"

I have checked for any other errors on the board with nothing visible, no heat, tried restoring with no screen, new screen, new charge port, different cable and different PC all with no luck.

Any ideas would be great!!

=== Update (12/08/2017) ===

Anyone got any more info on this one?? Does anyone know which IC the serial details are stored in?

I did have to replace the '5750 intermediate frequency IC' , but dont see that having any impact on this....?
