Tutorial: iPhone 6 won't boot after dropping into water


 Water damage has always been a common problem on cell phones, we received an iPhone 6 device from one of our customers, according to his description, the cell phone won't Reboot after dropping into water, how do we deal with this common problem?

After testing the iPhone 6, we found it cannot be charged, either, so our judgment is there are some problems on iPhone motherboard, power part or iPhone CPU burn out.

It seems that the iPhone logic board circuit is not damaged, so the iPhone 6 can be used after dropping into water. The reason that the iPhone 6 won't boot after using for a while is that the influent components are corroded.

Use phone opening tools to disassemble it, and then connect DC power supply to measure the current, the current stuck on 76mA. Disassemble the iPhone display screen, and measure the boot current, we found the boot current is normal, and the iPhone can enter the IOS system. 


We think the iPhone LCD Assembly is damaged, after testing, we found if the iPhone fingerprint flex cable not install, the iPhone 6 can turn on. Check fingerprint flex cable under the Stereo Zoom Microscope, we found traces of corrosion on the fingerprint interface.


Cleaning the corroded area，use Quick 861DW to re-weld the corroded pins, then assemble the iPhone and test it.

Finally, he iPhone 6 boot and enter into IOS properly, all functions are normal now.

iPhone 6 Display Failure after Replacing LCD

The iPhone 6 display is black after replacing LCD. After checking, the diode data of display socket is normal and all power supply for iPhone display IC  output is normal. Testing by  DC power supply , we find the iPhone current is abnormal. When press the iPhone power button, the boot current is obviously large. The current reached 100mA when press the power button. After remove the display tube, the current still the same, which means there is a short circuit. Measure the voltage output of each circuit of power supply with Fluke 15B+ Digital Multimeter , then surprised to find that there are really short circuit places. LD010 is short circuit; we suspect that the filter capacitance on the circuit has been penetrated. After remove the iPhone power control IC , we found it is ground short circuit. Open the WUXINJI Dongle  to check the iPhone schematic circuit, we found that this circuit is the display card image transmission MIPI data bus power supply. CPU brea...

Solution: iPhone X Won't Turn On

According to the customer's description, the iPhone X would not turn on after it drop accidentally. Then the cell phone reports error 56 when restore it. How did this happen? Let's test and repair step by step. Since iPhone X motherboard 2 layers are connected through the middle column, the solder points are very easy to get dropped. so we guess that the solder points from NFC chip to the CPU part have fell off. Disassemble the iPhone X by iPhone opening tools , remove the upper board off the main board, when separate the main board we see there is a row of points have fell off. Check 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. Then the tin of the middle column is repaired by iPhone X BGA reballing ste...
