Simondariova, Upgrading and modding wasn't too difficult. I did do it before when I upgraded to the modified 1.09 so I could use a non-whitelist wireless card. I updated to 2.07 stock, removed my wireless card, updated to 3.05 backed up my bios, followed the instructions, made a modified bios bin file then loaded that to my usb drive with the extra files. downgraded to 2.07 stock, upgraded to the 3.05 moddified bios and put back my wireless card in my computer. Overall yes it was a pain.. but not too hard. My main goal here was to some how enable hibernate through the bios because I did everything on the software end to make sure that Hibernation was enabled but it didn't work even after all of the bios upgrades.
