iPhone 6 iTunes error 56 failures? 3 Methods to Fix It!

Many iOS device users may have received the error messages like iPhone error 56 or iTunes error 56 when they are attempting to update or restore their iPhone.

The customer failed to update iPhone 6 IOS by WIFI network at home. When we received the iPhone; it is in iTunes data cable mode. We need flash it again by iTunes, when the flash progress bar reaches 80%, iTunes reports unknown error 56 (the failure has camera power supply circuit and NFC). In order to fix iPhone more efficiency, it's necessary to measure the iPhone camera circuit; The result is that the camera circuit is normal.

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 multimeter, 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.

Slove iPhone X Won't Turn On

Customer delivered a iPhone X and described the fault is not to boot after the phone drop accidentally. It reports error 56 when restore the iPhone X. How to repair this fault? Because iPhone X is the two board connected through the middle column, it is easy to drop the point. It may be that the solder points from NFC chip to the CPU part have fell off. Take apart the iPhone X by iPhone Screwdriver Repair Tools , take the upper board off the main board, when separate the main board we see a row of points have fell off. Picture 19-3-1 Look at the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56. Picture 19-3-2 Then the tin of the middle column is repaired by iPhone X BGA reballing stencil , and the AP part is welded bac...

IPhone 6P Front Camera and Distance Sensor Fault

Image
Received a iPhone 6 Plus, the customer said that the front camera can not be used, and the distance sensor has problem too. The two failures are concentrated on the front camera flex cable, which is likely to be caused by the damage of the wiring. First, we have to eliminate the possibility of the external parts fault, then consider the motherboard problem. Remove the screen assembly and replace it with a good one, we still can't turn on the front camera and use the distance sensor. Disassemble to measure the ground resistance of the front camera seat of J1111 by Fluke digital multimeter , it is found that several pins are infinitely large, and the related inductors are loose when touch with the pen. It seems that the small components are pseudo welded. 19-1- 1 Remove the motherboard and observe it under the Trinocular Stereo Microscope , we can see that the touch was repaired before. 19-1-2 The back of the sub touch chip U2402 is the front camera seat J1111, an...
