No unfortunately i don't remember the original firmware because it's not my phone it's my friends. I have a gdfs backup from when it worked but i don't know if that may help.
I've tried the driver from firmware R6BC002, R8BE001 and R8BA024. And i've also tried some original w580 driver but it dosen't work.
I can post the drivers here so you can look at them.
And none of them worked i may add!
