iPhone X can't boot, this is the repair step!

A customer sent us an iPhone X for repair. The fault described was that the iPhone did not turn on after it fell, and reported an error 56 after recovery. How to repair it? Please read this article!




The iPhone X is connected by two motherboards through the middle column, so the pins are easily lost. Now, it may be that the pin from the NFC chip to the iPhone CPU is dropped.



Check the iPhone schematic by WUXINJI Dongle, which is surrounded by the ground and 6 useful pins are dropped.


The ground lines are no need to fill, we just need to fill these 6 useful pins, we can check it under the Stereo Zoom Microscope. These all are the signal line of the NFC chip, so when we restore iPhone by iTunes, it reports unknown error 56.



Next we need to plant the tin in the middle column, and then re-weld the AP part.



Install the iPhone motherboard, assemble the iPhone, and then re-flash it again, now it flashes smoothly, all functions tested are normal, the repairs end!

This fault is because of the solder pins that from the signal of NFC chip pass through the middle column to iPhone CPU was dropped off, and then it causes iTunes error 56 on iPhone.
