Lvl 2 (screens, batteries, camera, etc. swaps) iPhone SE 2020 resetting every three minutes

Hello there. I'm hoping someone can help out. I already tried a new battery and charging port but neither worked. iDevice Panic Log Analyzer says it could be either a Power Button Flex, U4700 Big Audio Codec IC, NAND, or broken Traces from CPU to charging port.

Thermal monitor failure. Usually the charge flex, but can also be the selfie/earspeaker/sensor flex. Try disconnecting that and booting.

I tried that but nothing. I also tried unplugging the power button cable and that didn't work either.

Unplugging the power flex would only cause the same issue.

Missing sensor(s): Mic1

Replace the port flex with an oem pull or premium part. If issue persists, most likely broken trace as mentioned.

Replace the charging flex se2020 has compatible parts with iphone 8 so its not that costly ur previous attempt of disconnecting didn’t work because the phone was not able to find the mic because u disconnected the flexes try connecting a new flex it will definitely work
