MacBook Pro 2019 Boot Looping

[DalekSec]

Afternoon All,

 

I've just replaced a screen on a MBP 2019 (which i've done few times before). But this one is now in a constant boot loop. I've tried the following:

 

SMC , NVRAM reset

Recovery modes (wont boot into cmd+R, online recovery just keeps looping)

Booting from a USB installer, also loops.

Disconnected and reconnected battery.

Diagnostic mode doesn't load either.

 

Run out of ideas now! Anything else i could try?

Tried that along with restoring via AC2 from another Mac. This it's dead as a dodo
