|3 Minute Restarting
|iPhone SE 2020 models require certain sensors to be detected by the operating system, otherwise it will reboot every 3 minutes & record this error in the panic log.
There are 3 sensors that must be detected.
On the Charging Port, there is:
To find the panic log on the device, go to Settings-> Privacy-> Analytics & Improvements-> Analytics Data-> Scroll down to the files starting with "panic-full..." & click on the most top one.
On the Power Button Flex, there is:
Alternatively, you can use a tool like the iDevice Panic Log Analyzer, which will download the panic logs from the device & display them on the PC & give you suggestions to possible solutions. It makes it easier to browse the panic log file.
If you find the above errors, replace the appropriate flex with an OEM or Premium flex.
It is also a good idea to keep a known good power button flex & charging port flex in your bench, for testing only. There are reports of even NEW flexes being bad. So you have to keep known good flexes on hand at all times, so you don't waste your time troubleshooting with possibly bad flexes.
In scenarios where you have the appropriate flexes plugged in, but it still restarts, then you either have:
- Bad or damaged flex
- Low quality aftermarket flex
- Other flex cables that are Liquid Damaged
Please note: You MUST have the required flex cables, Power Button & Charging Port, plugged in. Otherwise it WILL restart. You cannot troubleshoot this step by unplugging the bad flex.
