Things went wrong, I thought I had made a backup. ...Yeah no, apparently I didn't. That was an install ago. So I'm in need of a full, 1MB backup. Not a 512KB backup. If you have an SPI programmer or can do a FULL backup of an AMD RX 5700 XT or 50th Anniversary Edition (either worked, this screw-up was unrelated), I would most appreciate it. It'll be 1MB in size.

After flash, couldn't POST. Dumped full with a CH341A, overwrote first 512KB with stock BIOS, reflashed, can POST but no screen (ever). No extra GPUs, no onboard GFX.

*Edit* Clarification, AMD REFERENCE CARD. Non-branded.

Finally got a second junker GPU to use while trying to fix the 5700 XTs. I get 0FL01, even if using UEFI shell method to flash. -i or -ai reveals amdvbflash thinking it is a 256KB SPI flash (rom size is being reported as 40000 instead of 100000 (8Mb->1MB) SOC15 SPI...odd enough instead of GD25Q80C.
