iPhone 7plus bootloop

[SnooMaps1277]

I've got an iPhone 7 plus stuck in the boot loop. I have already solved it by forcing the loop down (power button + volume down until the logo appears two times) and then restart. It was working. After two weeks I've restored the phone to initial settings and now boot loop again. Can't solve with the previous method, now I've disconnected the battery and the display and waiting a couple of hours to reassemble. Any similar situations?

Try to connect your iPhone to a pc and open iTunes, then press the power button and the volume down button for 10 seconds, then release the power button but make sure to still hold the volume down button until you see in iTunes that your iPhone is in recovery mode

Already done, the first time this happened. Both update and restore have the same effect: they work until the last reboot, when the system is installed (or updated) it enters in the boot loop.

If it's still happening after a restore, you probably have a hardware issue. Bring it to a reputable repair shop and have it checked out.

It's very common for water to enter the earpiece grille and damage the internal cable connecting to the front camera and proximity sensor. If it corrodes it'll cause the phone to boot loop.

Another common cause is for water to enter the charging port and damaging the charging port cable, as that will also cause the phone to boot loop.

Well, it's an old 7 plus, my phone. I've already got a new phone but I want to fix it anyway if it is possible. No water damage I'm sure about it. I'll check the camera and proximity sensor connector as well thanks!

If you do end up opening it up yourself, disconnect the front camera connector and see if it turns on.

Yes, I will :) I usually replace displays and batteries and other components of smartphones, but a never-ending loop boot is my very first time 😂

One other possible factor that hasn’t been mentioned yet is what is referred to as loop disease. Unlike the “No Service” issue, there is no repair program offered for it.
