I make this thread for people who have bricked their bios on their r4(not the vbios), since the release of the A05 I have seen multiple people bricking their bios. The solution to this problem is really easy. Go to Drivers en downloads | Dell [Nederland] and download the .exe file. Use winrar to extract this file, you will have a file named like this QBR00EC.fd, rename it to M17R4.hdr. Now format an USB stick to fat/fat 32, and ONLY put this file on it. We are almost done!!! Unplug the batter
