Checking and Fixing iPhone 6 iTunes Error 56

As we known, each fault has an official name, same with the camera fault, error 56.

After we got the iPhone 6, we do thought it just happened Wi-Fi connect fault, but when we flash it, the error code 56 occurred on the screen, so  we need to disassemble it and check the IC parts. Let us start.

We can ignore the issue of iPhone baseband CPU, if iTunes reports unknown error -1, and then we need to repair iPhone baseband CPU part. But this iPhone can be used normally before flashing, so we suspect the NFC module is damaged; now we decided to remove the U5301_RF first.

Remove U5301_RF by QUICK 861DW hot air rework station, and the measure the diode data for bottom pin circuit by multi-meter, after measurement, we found it is short circuit.

Open the WUIXNJI Dongle to check iPhone schematic diagram, we know that this circuit is connect to NFC power supply, CPU, and two small capacitors.

Now, we first consider NFC power supply, put it under the 7-45X Trinocular Stereo Microscope, and use hot air gun, and use tweezers to remove it quickly, next to it are two iPhone touch ICs.

After remove it, we measure it again, now the circuit is normal, and then replace the new IC to it.

Now, assemble the iPhone, and flash it again, the iPhone flash completed successfully.
