Hey all,

Having some trouble with patching my T480 bios so I can access the advanced menu. I dumped the bios and believed I patched it correctly, following a few guides. However when I reflash the laptop will let out a musical chime and not boot. I've tried a couple of times to fix the patched bios however I've hit a wall and have no idea what I'm doing wrong. Refreshing the original gets everything back to working order.
Some searching has led me to believe it's the bios version that was on the laptop that could be causing issues. It's running 1.53 I believe and I saw people with 1.52 saying they had issues but I'm at a complete loss as to what I should do next.
I've attached a copy of my working bios and a copy of the patched one. Any help would be massively appreciated and sorry for coming with what is probably a simple problem.

Edit-

apologies I missed the rule about where to post. my SN is PF-0YY9FP

UPDATE: Used this dump I found here and it now recognizes ssds but the intel me section in the bios is blank and the system hangs randomly.

I need help. I have a thinkpad t480 and during an upgrade, the bios got corrupted. I found a dump on some website and now my nvme ssd is not being recognized at all. I checked the ssd and it works. Does anyone know why this is happening?
