ThinkPad T15 Gen 2 BIOS Request

[shiyab]

T15 Gen 2 (Type 20W4, 20W5) Laptop (ThinkPad) - Type 20W5
Serial Number PF3FBFTH
Machine type model - 20W5
Motherboard - nm-d353 rev:1.0

I have an ME error. I’ve already tried cleaning it by following the BADCAPS procedures, but every time I perform the cleanup, the PC stops working. I’d be grateful if someone could help.

hi try feedback

I managed to get the PC running; I now understand the challenges involved in setting up this hardware. There are two issues when swapping in a BIOS from another computer: one is the Embedded Controller version—which might conflict—since this firmware resides in the U5402 chip (the MEC1503 itself has no internal memory). The failure to recognize the PCIe slot or detect the drive is related to the ME (Management Engine); since it was already configured for the donor PC, the ME needs to be "cleaned" so it can reconfigure itself for the new machine. The ME version wasn't even showing up in the BIOS.
I can make a tutorial later with images so you can understand the process; I took photos of the entire process.
Bios and EC ver.

I’m not sure if I can post an external link here so you can see the full table; there is something strange about it—version 1.69 was removed from the table (the record still exists, but the files were deleted).

4G board, I have removed and computer post, but don't reconise the disc slot

NO, dont have none

Post a picture of that JWWAN1 slot (ofc after removing the black plastic cover)

[kalukramer]

Not that one... I meant the M.2 network card next to the SSD. Or is that slot not populated?

Cant do that, card is soldered on board:

Do what it says and remove or replace the non-whitelisted installed network card with a compatible one

After record the 2 bios (with winkey block changed) this is the result:

I have 2 file (U2201 and U2202) pulled from a working T15 with updated version of ME and bios fw, same model number, can i put them on on this one? (after copy data from previus)
Thank's
NOTE: I have 20 laptops (T15) with the same issue

The problem persists, but now the laptop takes a long time to start up, I'll leave a photo of my BIOS and the error here.
