I dumped and modified my bios using AfuWin64/AMIBCP but when i try to flash it back, i get secure flash verify fail. This is AMD platform so FPT won't work.

Any suggestions/ideas?

Reading flash ............... done
 Secure Flash enabled, recalculate ROM size with signature... Enable.
 - FFS checksums ......... ok
 - Check RomLayout ........ ok.
 Loading capsule to secure memory buffer ... done

OEM bios can be downloaded from here:

@jmandawg - Use this method, only pay attention to the last spoiler, and download the tools attached so you have that AFU version

Thanks for the suggestion, Unfortunately that version of AFU won't work with my laptop:

That's odd, it should work for that BIOS I checked BIOS type and version etc before I sent you the link.
There is another AFU that will work, but can cause issues later, and or brick the device right when you flash it, so I suggest against trying that, but if you want the AFU and info I will give to you.
If I do give you this file and method, you will need to make backup with this AFU First and then redo your modifications, then flash it back.

I suggest instead, you purchase a CH341A + SOIC8 test clip with cable and wait till they arrive, it's less than $7 total on ebay.

I can help you unlock BIOS, if AMIBCP doesn't do what you wanted, once you find flash/programming solution
