Lenovo Thinkpad T480 BIOS and EEPROM request

[Xargon1975]

Try agian with AutoPatcher.

Thank you for your response and for your assistance.
I attempted to patch the file you provided, but the issue persists.
The system plays the startup melody followed by a blank screen (no display output).
When I revert to the original file you shared, the device boots successfully, but the BIOS remains locked.

Hi, I've been trying to unlock my T480's BIOS for over two weeks now.
I followed all the instructions, tried AutoPatcher and other BIOS versions, but no luck.
I found out that if the CRC check is wrong, the laptop plays a beep and shows a black screen. I fixed that issue, but now I'm stuck at a stage where the laptop just shuts down.
If I restore the original BIOS, it asks for the password again and stays locked. What can I do???

Bios N24ET77W (1.52 )

Sorry, you are correct, did you have a look at it? How messed up was it?

[hoaca388]

I mucked around with my bios a bit too much and now it doesn't power on, however still charges. I'm suspecting a fried motherboard and ordered a new motherboard just in case.
I would be grateful for some help

Just a question, by unlocking the advanced bios menu you can exceed the temperature limit of the GPU and CPU?

Flawless and thank you very much :').what was the change?, if i may ask, im new in this literally since yesterday.

I extracted bios region from update and replaced it in your backup and performed a clean_ME with intel FIT. You are welcome.

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

follow steps from autopatcher
