The iPhone X won't turn on and reports unknown error 56, why is that? The iPhone 6 accidentally fell into the ground, and then it can be turned on as usual, according to our repair experience, we think it's the problem of the iPhone motherboard.
Conect iPhone X to the computer by iPhone lightning cable, and then use iTunes to re-flash it, the iPhone is failed to flash, the iTunes reports unknown error 56.
Disassemble the iPhone X by phone opening tools, take out the iPhone X motherboard. With the help of the PPD 120XL iPhone X pre-heating platform,we can separate the
iPhone X motherboard smoothly.
As we know, the iPhone X is connected by 2 pieces
motherboard via a middle column, so the pins are easy to lose because of
dropping. Now, it's possibly the pin from the NFC chip to the iPhone CPU that
was dropped off.
Check iPhone schematic diagram via WUXINJI Dongle, it's surrounded by ground lines, and the
6 useful pins was dropped off.
The ground lines are no need to fill, we
just need to fill these 6 useful pins, we can check iPhone motherboard 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 by QUICK 861DW hot air rework station, and then re-weld the AP part.
After installation, assemble the iPhone, and then re-flash it agian, now the flash process goes well.
