unlocking bootloader threads should have this warning in their tutorial.
my friend bought his x8 yesterday and went directly to the x8 Development Category,
at first its going smoothly until we turned off the phone for flashing, and after that it won't open. we checked the manufactured date and unfortunately its 12w04
and thought were so ****ed up, we tried manny procedure but nothing works.
as for now were praying to all deity that we know if the dealer would replace the phone without extra charge.
