Thinkpad T480s No Power after BIOS Flash / Won't power with original Dump either

[kuiri]

Hi I purchased a t480s with 16GB RAM and an i7 for very cheap.
The laptop worked fine, posted and booted to BIOS. I flashed a known working Libreboot image with a T48 and it wasn't posting.

I recompiled / rebuilt the image and tweaked libreboot build process a little bit and still wasn't posting. I flashed the original BIOS and it posted fine just once. So hardware must be fine.

I kept trying to make it post with the libreboot firmware and it wasn't working, despite the images working fine on i5 motherboards.... and now after flashing the original lenovo dump is not posting either.

The laptop charges the battery, and when the CMOS gets cleared the power button blinks upon receiving power. However upon pressing the button there is no activity.

Could I have just fried the EEPROM chip? I will attempt to desolder the chip from a known working motherboard but I am asking here first if anybody has an idea what could have gone wrong before doing that.
Thanks in advance.

I just noticed that I damaged the 33 Ohm resistors while using the clip to read and write to the SPI Flash chip. The traces are still there so I will use the resistors from a donor board and report back.
