Firstly, this relates to v2.0, I am not sure if it will work with v1.0
Secondly, I didn't note the BIOS version before I upgraded - I assume it was 'FA'
Thirdly, I experienced the 'boot loop' during a complete 'new' install with an Intel 3770K
If my experience is anything to go by, it may be that those suffering think the loop is indefinite ...mine was not. I left it looping in the hope that something changed. I do not know how long it was doing this for as I simply left it (I believe I came back to it within the hour, but not sure). When I came back, the screen was black other than a message saying that a boot device could not be found.
This allowed me to Ctl-Alt-Del and restart going back to the 'Logo' screen. From here, I was able to select End for Q-Flash.
NOTE - I was using a USB Keyboard at this point (I had tried PS2 during the loop to no avail)
I had extracted BIOS 'FD' to a USB stick, which was inserted into the USB port off the board.
When I chose 'Update BIOS from Drive' it reported that a drive could not be found.
I escaped from the update screen and started doing some restarts. I found that, in some instances, the keyboard was not active when returning to the Logo screen, but it was ok after a few seconds.
Eventually I used a different USB stick and it was recognised by Q-Flash which I used to update the BIOS. After this, no loop and I could access the BIOS without any problems.
Also note - I had disconnected my SATA devices before leaving the machine looping. I do not know if it was relevant to the message saying that there was no boot device (I don't see why it should be).
Hope that helps everyone struggling with this...
