820-3332: Progress bar loads about half way, then reboots and repeats this process

Hello, have a 820-3332, the Progress bar loads about half way, then reboots and repeats this process. But i can boot all the way to OS in safe mode (holding shift during boot) and run without issues. Confirmed GPU_vcore present. About to replace GPU but need to confirm nothing else could be the issue.
 
Regarding ME: I use CMIZapper Medusa 2 to clean the ME region, Also, used a Matt Card for this specific board to confirm.

Regarding the GMUX, the 820-3332 doesn't have this chip. Are you referring to the eDP Mux U9100? In which case, i did reflow that one as well.

Still same symptoms. Can only boot completely in safe mode.

If you get the real/correct chip, it should work without any changes.
ME Region is related/married with PCH...
 
Any tips on setting up the temp profile for the rework station. This will be my first time using a rework station (ACHI IR6500). I'm currently doing some reading on how-to. Going to try it out on some test boards first, once i get the profile setup

There is no universal profile.
You must practice on scrap boards and adjust settings according with your machine power and ambient.
As a tip, when rework AMD give a bit more heat to bottom side, than for Nvidia.
AMD Si die is more sensitive than Nvidia...
