Chosen Solution
Hi guys, right now iam working on iPhone 7 with bootloop, restore done sucessfully, 4 jumpers under audio + replaced audio ic from donor board but nothing does not help. I have 2 same devices with same problem. I tried also disconnect homebutton, front camera, rear camera dock but it does not help. Any idea where can be problem? Thanks

Did the boot-loop occur after the Audio IC repair or was the boot-loop the root issue and you tried an Audio IC repair to solve it? If the Audio IC issue was the original problem, then I would remove the IC, inspect my work and probe the system for shorts. You may also have caused issues with the BB subsystem so you should probably check that too. If the boot-loop was the original issue, then I would fully probe the PMIC and BBPMU to see if there are any issues with the various subsystems. At this point, you need to look for clues as there is no silver bullet “solution” (or some would say, “plz bro solution, 1000%”.
Bootloop after audio ic replacement main cause deu to BBCPU that was accidently happen by over heating.The ball under BBCPU popup and shorting internal pin.
