Hello arestlessknight,

It would be great if you could give us some information and the binaries. I have the exact same laptop:
Model: Lenovo ThinkPad T14 Gen3 AMD
Type: 21CG-S1D600
Serial No.: PF-4AFKP5
Mainboard Type: NM-E441 Rev: 1.0
BIOS Chip 1?: 25LR256EYIG
BIOS Chip 2?: 25LB128ESIG
Chip: GigaDevice

Do you also have both installed BIOS chips? Or which of the two is the correct one? See image.
