Repair: iPhone 6 Plus camera and fingerprint not working Issue

Image
The iPhone 6 Plus fingerprint function, rear and front camera all unavailable. Customer described that he repaired the iPhone black touch IC , it is possible to put the back of the component virtual weld. Anyway, we need to fix it step by step. First of all, measure the diode data of rear camera adapter with Fluke 15B+ Digital Multimeter, no exceptions found. Then measure the rear camera power supply. Picture 14-6-1 Measure the main camera 1.8V and 1.2V power supply, when we measured the 2.85V power supply, we found that it had no power. Check the iPhone 6 Plus schematic diagram on WUXINJI Dongle to trace the 2.85V source. Picture 14-6-2 We found that the 2.85V was converted from the main power supply through U2301. During the repair process, short connection A1 and A2 pin can quickly determine if 2.85V power is causing the iPhone camera not working. After short connect A1 and A2 pin, get into IOS to test the iPhone rear camera, it can be turned on now,...

The customer sent us an iPhone 6s needs to be repaired, the fault described is that it reports unknown error 4014 when flash it. After detecting, the current is 57mA, DFU mode, flashing it and it reports 4014, which is consistent with customer description. Disassemble it to check the iPhone motherboard, the iPhone Nand flash on this motherboard has been repaired, and when check it under the microscope, we can see that the iPhone NAND flash damaged. Remove the iPhone Nand flash and measure its diode data, it is normal. Put Nand flash into the WL PCIE Nand programmer to test it, unsurprisingly, the NAND flash is damaged. Picture 14-2-1 Replace the new iPhone Nand flash and flash it again, the fault still exists. As we know, the iPhone 6S and later iPhone reports iTunes error 4014 mostly caused by nand flash and baseband issues. However, after measuring, we know that the iPhone Nand flash is good, so now the problem is iPhone baseband . Measure the diode data...

The iPhone 6SP was dropped down accidentally by its owner, there are various fault we need to repair today: iPhone rear camera , WiFi, audio, volume, photoreceptor, card setting. The heavy damaged iPhone 6S Plus actual apperance is shown in picture 1-1-1. It can be turned on when using multimeter to trigger but the current is a bit large. No matter what, we have to turn on the handset and enter into system to have a test. The first problem is card setting. Continue to test other functions, it is true that the front flex cable, audio key flex cable, and rear camera are all broken, so we have to replace all of the spare parts. The last fault we need to confirm is motherboard: card setting, bad WiFi, audio recording is not available, bad audio and leakage. Triggered with more than 300 mA current, which means it has problem.

We all knowledge, when your iPhone was dropped before. And then the iPhone shows no service. You will be very anxious and angry,Following this article, The VIP Pro Shop Team will help you solve this problem. According our experience, we suspect that the no service fault is caused by RF circuit. Now let's verify it. Firstly, disassemble the iPhone by JM-P01 Essential Toolkit , and then carefully remove the iPhone motherboard. Observe the iPhone motherboard appearance, no obvious scars. Secondly, use multimeter to measure the several main test points, we found that the diode data of testing point PP3170_RF is larger than the normal one 0.406. Thirdly, plug the WUXINJI Dongle to computer and then open it to check the iPhone circuit diagram, we found that the test point PP3170_RF is the clock signal RFFE1_CLK of RFFE bus input by baseband CPU. Checking the PCB bitmap, we can see RFFE1_CLK’s signal is sent to many chips. Fourth, with the help of hot ai...
