I purchased a CH341A USB programmer, connected it, loaded drivers and got it working.

I flashed this ASRock motherboard with the current ROM code (erased, flashed and verified).

It is still broken and stuck in a boot loop. So no, I'm not buying a defective Intel CPU caused this. B.S. It does the same thing with a brand new CPU.

I flashed it yet again. Same outcome.

I tried it a 3rd time with older code but the programmer will no longer recognize the flash chip. I do not know if it is the chip or the dinky low quality chip clamp. It looks very low precision. I have ordered 3 more different replacement SOP8 clamps. Yes, I am stubborn to a fault.

My hope is to try going back to earlier BIOS versions to see if that makes a difference. If I cannot revive the board I will make a video testing the boards ability to deflect .308 caliber rounds and post it to youtube. The murderboard gets murdered. I guess in reality it suicided itself first.

Thanks for the chuckle, definitely would watch that video. Could be some trick to
flashing the ROM. I remember on some BIOSes back in the day I had to double up the
code (2 copies) so that the board would recognize it. Unfortunately I have not
flashed any of these newer boards so I can't offer any suggestion here. Maybe
check out google and see if anyone else has flashed a Z790 (any brand) and see
what they did.

Good luck.
