You most definitely can roll back, it just takes a little work.
Their is a guide to using afudos to roll back in this forum. If you follow this forum https://rog.asus.com/forum/showthread.php?99490-Flash-any-most-Asus-motherboard-Bios-in-DOS-with-USB... you should be back to normal with no problems. If you are unsure about what to do after reading through the guide message me and i will try to explain it better.
Problem is we cannot roll back to a working one....I talked with tech support-at least not the ROG Strix B450-f
Hello, to anyone out there getting ready to update their bios to 2406 DONT.
I did so this morning 7/09/19, and it has issues. I have a strix b450-f gaming board, and used to run cool and quiet "no pun intended" at 22c @ idle and 55c max @ 100% load for any length on my 1700x with a hyper t4 cooler. After the bios update not only did the mouse quit working in the bios but my temps went to 33c @ idle to 65c @ load. This is not good. I warn you please do not update. if you have updated use afudos with bios 2301 to fix your issues. If you need help doing this i am here and will be checking post.
