Asus BIOS upgrade causes continuous restart

I recently upgraded my BIOS, although I forgot to rename the file. I went ahead and did the BIOS upgrade; it went successful. That is until I restarted, I see the Asus logo as well as the option of pressing F2 or DEL to enter into the BIOS but even if I try this; the PC immediately reboots and it does this non-stop.

Therefore I installed on a USB key the previous version for my Asus motherboard, as the one before was the latest. I tried the EZ-BiOS update, it doesn't work. It reads the USB drive but doesn't apply the BIOS update. I also accessed the connection for the batter, disconnected this in all these cases the BIOS won't boot past the Asus logo; the EZ-BiOS downgrade BIOS upgrade won't apply. How do I resolve this ?
