Since the release of the iPhone 7 and iPhone 7 Plus in 2016, there has been many strange issues affecting these models. Most of them are audio problems. In appearance, the phone looked in good condition: no oxidation, it was never disassembled before, no water damage, no overheating and the replacement of all the usual parts such as the earphones and speakers did not solve not the problem.
However, there was still an issue, most likely linked to the logic board of the phone. Unfortunately, after a year the phones were out of warranty, so Apple no longer wanted to replace them. It was therefore necessary to call on super-repairers: the experts in micro soldering.
An inspiration to everyone on this issue was Jessa Jones of iPad Rehab who identified the problem and came up with a solution fairly quickly. The American micro-soldering community is very developed, which is not the case in France.
This guide shows how to identify and solve the problem.
Possible symptoms:
The problem: The audio chip U3101 is disconnected from the logic board. The iPhone 7's logic board may be slightly twisted and often results in a broken track.
To reassemble your device, follow the instructions in reverse order.
