BIOS bricked and can't get into windows

[cave.357201]

Hello, I have a problem with my BIOS on my ASUS Z97-A USB 3.1. Ive been experiencing problems with my bios after overclocking my 4770k. It would freeze upon entering, but I could still get into Windows. I was able to fix the bios and upgrade to fix errors, updating it to the latest 3501 BIOS version. I then bought a samsung 970 evo ssd. In the onboard components section, I switched a pci mode from the 4x to m.2 and overclocked the cpu to a max of 4GHz. I saved and rebooted and thats where the bios bricked. The bios now froze every time I attempt to enter it and there is a blinking cursor and black screen when I try to boot up windows. Does anybody know what I should do? I would like to try to not have to rma it because I use this system much. Any help is appreciated, Thanks.

asus dropped another bios it 3505 a beta bios. with m2 drives when used some of the sata ports get turned off. if you have reg sata drives in the system unplug them from the mb (data cables). if the bios is working and there no os on the m2 drive it should time out. if it wont try clearing the cmos to get back into the bios.

Worst comes to worst try to reset the bios by removing the battery.

Hopefully this gives you default settings and erases the bad settings.

I've tried both putting sata cable in different ports and removing the cmos battery and nothing worked. I tried the memok button to see if that would do anything. It said memok and f1 to enter setup but on obviously that doesn't work so I am a bit stuck on what to do.

Edit - I think I downloaded bios version 3505 not 3501, my bad

if the bios was flashed with the wrong bios it do crazy things. to try and fix your issue look under bios recovery in the mb user guild. you need to download the bios file (last one). from asus. put it on a usb stick unzipped. make two copies. leave on named as is in the download. the other there is a .cap file under bios recovery to rename the file. put the usb stick in one of the slow usb port and turn on the pc it make take 20 min or more for a cmos recovery message to pop up.
