Thinkpad T14 Gen 2 (20W0)
SN: PF-2WQMVG

Symptoms:
30 second black screen on boot
EC firmware number not listen in BIOS
NVME drive not detected
Can only boot into a Linux OS with compatibility options turned on (Not using IGPU I presume?)
Cannot boot into an OS otherwise
Network card and ethernet port not functioning

Initial problem:
Didn't boot/intermittent boot. Black screen with nothing showing up

Attempted Fix:
Flashed new EC and BIOS, did not clean ME (I was getting errors with the intel tool)

Other symptoms:
Bios dump seems to be partially corrupted, ME analyzer was throwing up an unable to read error at 0x29000


Any help would be greatly appreciated, I'm very grateful for anyone who takes their time to look at my issue

BIOS and EC binary dumps have been posted below.

I have attempted to flash the provided EC and BIOS binaries. When they are flashed to the board, it does not boot under any condition. When I flash the files provided for the 20W1, the board boots into the BIOS, but the issues mentioned in my original post appear. What may be the issue causing this?

Thank you for taking your time to help me on my issue

[qayyum786]

keep your original ec and flash out image only
if no luck than flash 2nd one both ec and main

None of these worked, so I attempted to re-flash the dumps that at least let the laptop POST. After this, the laptop doesn't post and just has a black screen with a charging port LED that lights up.
I'm out of ideas here, but thank you for everyone who attempted to help me, I really appreciate your time and effort .
