thanks and best regards

Have you tried force restarting your iPhone? And how about assistive touch function? If nothing works, it is advised that you should try a third-party tool such as TunesKit iOS System Repair to fix your iPhone's system glitches that may cause your problem.

Hi rai04 from lovely Philippines

You can login on www.icloud.com and reset your apple id password. By choosing you forgot it. If that doesn't work for you. You can look at YouTube and search for Apple tech 752 iPhone 5s bypass to activate.

Sure you can force the board to enter DFU mode.
It is a test point on the backside of the board. It is hidden under the sticker.

Connect ground to TP0714 will force to boot in DFU.

But most likely you have a broken button flex and thats why you can not boot in recovery. Try first and other on off button flex

You have to reball or repair broken pads on the mainboard. sandwich boards have a broken connection. All Network ic's are on the lower board. To activate the phone, the server will request information form the lower board.

Audio codex IC U4902 is responsible for audio when calling. I did a few xs that had crackling sound or no sound when calling. You can twist and bend the frame to test if the sound change. That will indicate if this ic has a bad connection. Replace or reball this ic. Be careful, It's a bit tricky repair. since it is next to the cpu. Hope you have the skills. Good luck.

You don't need a schematic. Every ipad is the same. 2 backlight filters at the display connector. 2 diodes under the shield, 2 coils and a driver ic.
Most of the time the filters or diodes burn.. Always disconnect the battery before connecting the screen.

can You show where is it on the board ?
Can i rehot it ?

eldavies · 04-03-2021, 21:02

Cant tell you exactly where it is, but as HDccam said, most of the time it's a burnt diode or filter. They need to be replaced, "rehot" will do nothing.
