Force flashing older bios version on AMD X370 Motherboard
I own an ASRock X370 Taichi motherboard. I bought it used off ebay with the first round of Stimulus checks here in 2020. I own a Ryzen 5 2600 processor. When I bought it off ebay the seller had flashed the most recent bios version off the website, which was version 6.20, with AGESA "Combo-AM4 18.104.22.168 Patch B". I have had instability and blue screens and crashes for the first 2 months until I looked at the bios listings on the ASRock website for my motherboard. For reference here is a link to that so others can read it: https://www.asrock.com/mb/AMD/X370%20Taichi/#BIOS There is the message posted for the 2 most latest bios's here: "*ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system." Okay.. I have Pinnacle Ridge, so I back-flashed backwards to the latest bios that does -NOT- have that message, 5.60 and ever since my system has been completely stable now and everything is golden.
However tonight I was reviewing the bios versions here and there is an older bios listed, 5.10 which apparently has AGESA version 22.214.171.124 ... !!!! Lots newer than the AGESA 126.96.36.199 that I'm currently using from bios version 5.60 right now. However they won't allow us to flash it backwards in bios to an older version.
I do have physical tools here to "clip on to" the bios chips physically and force flash a rom into them. I was considering doing this with an older bios version but I wanted to ask here first if anyone has tried this and if I try it is there a risk to brick my board just from going to a different bios version?
Win-raid might have a solution, just gotta read on it. Only thing is, backup (twice and verify) your current bios binary and don't flash the stock bios because it comes without serial, UUID and LAN MAC address. Without these windows activation along with anything else dependent on it will fail on boot.
