    iPhone 7 keeps restarting infinitely

    Hello, I have an iPhone 7 that is stuck in a bootloop. After the Apple logo, screen turns off and it restarts in a loop.

    If I remove the front camera/proximity sensor the problem goes away and the phone turns on normaly. I replaced the front camera with a new one but the problem returns again.
    I would apreciate any help.

      Ok, after some more testing I figured out that the cracked home button was the problem. Can it be replaced?

          hi, search for jc home button for ip 7 , but replacing home button would mean you would lose your touch id.

              Hi. Do watch the videos here on the topic:

              https://blog.puls.com/iphone-7-loop-disease

              This guy discovered the fault and Apple had a class action law suit against them that covered the repair costs for at least the iPhone 6 I believe.

              If I recall correctly, the issue is that over time, the audio ic becomes undone off the pcb due to the pcb layout and where the audio ic is located. Due to repeated stress in this part of the pcb, the audio ic is no longer able to communicate with the host i2c interface. The host i2c controller then keeps retrying / looping the os to find this missing audio ic.

              Your issue could very well be the same. Many videos on this fault and repair on youtube.

              I would suggest that you contact this same repair shop to ask for their advice. I believe that he is in Spain. Kudos to him for this discovery.

              Please do update this thread with your progress.

                  Audio issue phones have not bootlooped for over a year now, unless the phone has a very old iOS on it.

                  Audio IC itself doesn't get loose. Only one certain trace gets a microfracture and that's enough for it to stop working.

                          Hi,

                          I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                          MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

                          LG L192WS-BN backlight turns off after 1 second
                          by www
                          I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.

                          I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue....

                          Samsung UE55F8000SZ Turns on and off immediately
                          by Egidio85
                          good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
                          This defect happens continuously, hearing the classic click of the relay every time.

                          Power supply board BN44-00636B

                          disconnecting the mains and lamps from the power board always causes the same problem.
                          Is it normal that without anything connected this power supply turns on and off cyclically?
                          any suggestions on what to check?

                          thanks in advance
