Just flashed the latest BIOS (7B93v19) for this board. No major issues as a yet except enabling Secure Boot causes a no boot scenario. Work previously but its looking like after BIOS loads it doesnt make it to the OS, just a blank screen.

Same issue here on my x570 Gaming Edge Wifi. It worked on new August BIOS but not September. Even after deleting and reloading keys it does it and I'm thinking AMD changed something in either keys or key handling. Won't know for sure unless I try a fresh reload of the OS and am not going to do that for quite a while.

X570 Tomahawk here. Haven't been able to secure boot for the last 3 BIOS updates. Does the same as yours, loads BIOS and then sits on a blank screen.

if flashing back to older BIOS fix the problem, it's the BIOS issue for sure and hope MSI will release an update soon.

Issue were duplicated and MSI are aware of this issue now and they are working on a solution, but will take a time.
I will be back to you here, once they got a solution for this issue.
In meantime if you need to use secure boot, then flash back older version temporary until the solution come out.
Thanks for your patient.

Today I did flash newest bios E7C37AMS.HA0 on X570-A Pro, but cannot run secure boot.
(This newest bios contains AMD's latest AGESA Combo PI V2 1.0.8.1 microcode).
Found in this forum about this problem and I will wait for a solution by MSI.
Thank you for the useful information.

After contacting MSI support I did receive a link to the newest BIOS E7C37AMS.HB1 dated 18-Sep-2020.
This solves the secure boot issue.

Is there an update for the B550-A Pro? I just updated to A30 and have been tearing my hair out over this issue, and I'm hoping an update will fix it! Thanks in advance :)

Don't know if there is such issue for this board, but there is no such BIOS.

I haven't flashed the latest version to mine to verify, but there were reports on reddit of this issue being present on it as well.

Regardless, thanks for the b550-a pro bios, I'll check it out tomorrow!
