Does not work on ThinkPad T14 AMD Gen1

[pomoke]

UMAF does not show a working menu on a ThinkPad T14 Gen1 (AMD).

Here's part of message:

SetupBrowser
No of Handle - 2
Could not load the image on Handle 0 - Not Found
Image Returned - Success 0

Is this a UMAF problem or bug of EFI firmware?

[SKUndef]

I have the same problem, it gives 3 of those errors and then black screen.

most of Thinkpad bios require more effort to get it to load,
and I didn't spent time fixing/implementing it.

I met this issue, too. Some measures may taken by Lenovo to enhance the bios tamper detection in the newer version of BIOS, the document is herehttps://datacentersupport.lenovo.com/ai/nb/product_security/ps500554-thinkpad-bios-vulnerabilities
I`m gonna try to downgrade my BIOS version and try again. My device is X13 GEN3, however, I think it may be practical for each ThinkPad device.

Whats more UEFI Variable protection was mentioned in this document, which means that the existing way of modifying BIOS by editing UEFI variables will be ineffective on ThinkPad devices, thats a tough one.

I'm on a Thinkpad T14 Gen 3. The took seems to boot for me on bios version 1.46, but it cannot save changes.

Still no fix for me, I too, am on a thinkpad t14 gen 1 amd with a pro 4750U, the tamper protection bug isnt present on my thinkpad, do you think there will be any way to fix this in the future?
