Chosen Solution
Replaced the screen and rear housing. Used all the original parts from the old housing. Device starts up, stays on for 3-5 minutes, then it restarts and the cycle goes on. Disconnected various components: Proximity/Top speaker , Dock, Sim tray, Front Cam. With no change in the routine. Used a different battery and screen to test as well. Device storage is rather full, only 1.5 gig free. Any help please.
If the X and above don’t have an OEM charge port or can’t communicate with the charge port properly, it may lead to an issue like this. Try replacing it with a premium port from Mobile Sentrix.
