This guide is several years old, and should probably be removed because /GAN method is a legacy of dark ages, and doesn’t work for newer boards. I wrote it because of a promise given to Fernando, and already asked him to remove it once (because of people breaking their systems by following the guide).
Here is my second try: @Fernando , please consider removing this guide as both dangerous and severely outdated.
I agree with CodeRush. The guide has been kept for archival purposes with a warning at the top but is now non-sticky and closed.
@CodeRush :
Thank you very much for having started this thread in January 2014 by writing your detailed guide, which was absolutely helpful for a lot of users. I apologize for having not followed your request to remove this thread from the Win-RAID Forum. Your guide and this thread contain so much interesting information, that its complete removal would have caused a big knowledge loss for all interested users of this Forum. Nobody among our Forum members knows so much about the BIOS secrets as you. That is the reason why I was and still am very grateful, that you had written the Guide, which is still available within the start post of this thread.
I sincerely hope, that you accept plutomaniac’s decision to write a warning on top of your guide, but to leave the text of your guide and the complete thread untouched.
Thanks again!
@plutomaniac :
Thank you very much for your actions regarding this thread, which are 100% supported by me. Addditionally I have removed the hint to CodeRush’s guide and this thread from the start post of >this< thread.
HI Scholar53,

Thank you, can you tell me how to downgrade (rollback) or if there is a member who knows how to do it so I can contact them?
And have you tried to use the search box of this forum and look for term “downgrade”… the presented tools/methods here in this thread are for old AMI Aptio IV Core bios, not for current V and modern mb models, methods will varie from model to brand and not always an easy task or possible, with a possibility of a broken system occur.
Your Z590 Hero has USB BFB feature… have you tried this method?
Yes, I used USB Flashback, but it didn’t allow me to rollback to previous versions. The Asus website said that USB Flashback allows rollback, but it doesn’t work as they described.
With AMI Aptio V, I can not find any solution out there
USB BFB is a “blind operation” with system power off… so your answer has no credit at all.
Try again… but this time doing the correct operation… these are not for doing with Asus APPS, UEFI or in Windows environment.
USB BFB doesn’t uses a powered system or post any messages/checks bios versions…so please do not make us loose time with it.
Over_N_OUT of here.
