First of all, thanks for this! I used this to upgrade from 4.1 to 5.1. I got the firmware file from xbin. When I ran this it showed me two options, 5.1.0 or 5.1.0 Exfat. I selected the Exfat option. I have checked my fuses and still only 5 burned, so it's all good. I am able to boot 5.1.0. A 64GB exfat sd card is detected, but when I open the homebrew menu it says there's no homebrew, I do have a switch directory in the root of the sd card, actually if I boot with a fat sd card this works fine. Did I pick the wrong option? Should I restore my nand and start again?
