I have downloaded setool v0.914014 and v0.9130096 and I'm getting error "Protection card error" Is that because that is not payed version? Is that the program I need? Or I need the real box(physically, with diff cable, not flash usb)? There is no other way to repair it? Can I use gdfs from my friends phone couz he is having the same k550i as mine. Can I write his gdfs and back up mine? What is going to happen then? (Sorry if I'm boring and sorry for noob questions) Thanks...
