It is for a different motherboard, but the flash device is exactly the same!
(I took a snapshot with my camera to make sure it's the same chip and it is).
I tried this last night without success (till 3am ), but today I tried it again, and managed to get my backup BIOS to flash the main BIOS!!!
I had EVERYTHING disconnected (especially disconnect the HD, it tries loading a backup from there and keeps failing when it manages to boot).
Take your BIOS battery out, only keep 1 DIMM of RAM, the GFX card and a keyboard.
Keep trying to short circuit the pins in the picture of the main bios, you may get odd results, but if you don't give up you may just revive your board with F4!!!
Method that worked for me is to short circuit the pins a bit after power on.
I can't take any responsibility if you totally nuke your board, but I'm pretty sure this method is safe (as long as it is done correctly), because at times I would short circuit the pins like no tomorrow (believing there is nothing that can be done to save it). So if mine survived, I'm pretty positive yours will do.
Try to spread the word regarding this, so people don't have to pay for a new mobo!
I don't know about you guys, but I am NEVER touching GIGABYTE again and will NEVER upgrade my GIGABYTE BIOS!
I wish you all luck in unbricking your motherboards and thanks all for the support!!!
