Best fix iPhone 6S Plus many issues after dropped

A customer sent us an iPhone 6S Plus to repair,  the issue is that the iPhone accidentally dropped into the ground, and then the iPhone has been badly hurt, such as iPhone rear camera, WiFi, audio, volume, photoreceptor, card setting all has problem. How to best fix it? Keep reading.



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. Now we should solve the fault one by one.

Since we can't get into the setup, so we take off the iPhone 6s Plus WiFi audio first. The result is the same. There are much solder points are dropped at the bottom of WiFi, it damaged very serious. 30 pin is still on the iPhone 6sp motherboard, but the value is measured with 0L (infinity), certainly it's not normal, so we are going to solder the jumper wire, and also do jumpers on the other disconnected parts.


The jumpers in this repair are easy to do. A tip for new repairman: It's better to leave more jumper outside if there is enough space, so you can extend wire even there are other issues existing.

After soldering jumpers, install the motherboard to test, there is no card setting. We had always thought that only WIFI was not good and that the card was set on the board, and the WIFI would not be stuck. Today, we can see it's same if WiFi is removed off, after intall WiFi, the signal is very weak, it seems that the board layer is broken again, direct solder  jumper wire to the opposite track. 



Now the signal is normal, and then another iPhone 6 plusaudio IC chip can be replaced, the whole repair process is finish here!
