I tried gkmltd, 2301 to 22xx or less is blocked. I also switched to the second older bios (not supporting Raptor Lake processors) but unfortunately without any succes despite many attempts... Maybe I could flash using an alder lake to boot to the setup of the second older bios, but I do not have one around me...

Many thanks for your reply bscool ! Seriously these practices should be forbidden. Owners should be able to install any bios of their choice whatever the reason is. We all know that OC results might vary depending the CPU and memory we use... BCLK OC of the i5 12400 for example is no longer working from 2004 version. I know that most APEX users are more after high end CPUs anyway but still this is not fair to lock the ability to flash back a previous version of our choice, potentially losing some stability or previous working feature. Personally, I use that motherboard mainly to run tests on different CPUs / Ram. Does someone have the detail of the "improvements" provided with this 2301 version? As I couldn't find it on the ASUS website, it looks more unofficial maybe tweaked to me... Thanks for your feedbacks.

Installed that unofficial 2301 and now stucked to it, it won't let me to downgrade to any previous version anymore, please advise ! Thanks.
