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

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
