Can anyone help me unlock a W810i Cid 50? I have Setool lite and X++. I tried flashing W810i with X++ and it just turns the program off. Manage to flash it with Setool lite and it sorted out white flashing screen but tried to patch it and it just came up error. As I've been reading it seems you can't patch a Cid 50 is there anyway of unlocking it for free.
