OFFICIAL Bios ver. 2004 will not allow bios flashback THREAD

[mr_allroy]

Hi all,

It looks like at least a couple of us have an issue flashing back to earlier bios with ver. 2004. Both with the UEFI method and the usb flash back will not work (3 usb drives and none worked). The bios setting to allow this is enabled. I have a Z690 Hero.

If you have this issue please reply to this thread so we can keep all the info in one thread. It will help if you list your MB model as well.

Thanks
( I should also note that the voltage issues found in ver 1720 appear to be fixed in 2004.)

UPDATE - It seems that real time ram timings can't be changed using Memtweakit or any other tool. Was working on 1601. Can anyone else confirm this?

Now you guys have stopped bickering... has anyone heard back from Asus regarding this problem. XMP profiles are not working on the new Bios and this has been widely reported.

I sent support an email and all they did was ask for photos of the motherboard settings, on the email I said I only picked xmp profile options..

Try to send them an email as well, the more people complaining the better.

Just wanted to write a warning and request any guidance for anyone facing something similar or who may have resolved this.

It appears that version 2004 for multiple ASUS motherboards breaks Thunderbolt capabilities. This happened to me unfortunately, and without knowing I wouldn't be able to roll back I am now stuck with a PC taht is useless for my work (what I purchased it for). I work with many Thunderbolt devices and rely on this every day. Just wanted to warn anyone considering updating to 2004 (which is an irreversible BIOS update) that they may lose Thunderbolt functionality.

I started a thread for my issue if anyone can help me out that would be greatly appreciated:
