I just tried se tool light and got a blue screen 40 seconds after (I'm using Windows 7 - so I'll try to find a computer with XP or Vista)

But which firmwares should I use? I've already downloaded K770_R8BC004_MAIN_GENERIC_VI_RED52.mbn.

Tools installed / downloaded:

USB drivers
SETool2 Lite v.1.11
XS++
SIMLockPatchGen_v2.2

Help :D I'm blank..
