Flashed back. Totally same.
Flash update error looks like this....

Need help... BIOS is not locked, system starts and perfectly works from USB but device hangs during POST if any SSD presents in its M.2 slot inside the case instead of connecting via USB3 and USB-M2 adapter as I have to work for now.

This issue has appeared after macOS update (yes, a third system on it is Hackintosh).

First time I've got this problem after same action - the seller simply changed a whole device by warranty. I've thought it was a hardware problem with SATA controller. So now I think that system updater rewrote some UEFI areas - CMOS battery removing didn't...

I'm web programmer and retro hardware fan, and through this hobby I've got repairing skills, so now I can repair electronics by myself for me and my neighbourhood (for a reasonable fee, of course ).
