When I did the wire trick back in August I found it didn't work until I tapped the wire against the case a second time. Try it as instructed and if it doesn't work try putting the wire on the metal case, sticking other end of wire In the hole, pull it out, wait a second and stick it back in. That's what worked for me.
P.S.
I went back in the posts on this site to when I did the wire trick on August 5th of last year. I read my post and what I learned then that I wasn't told anywhere else is
1.) once you run the controlbear.exe program you have to go forward. There is no turning back unless you successfully complete wire trick.
2.) you have to put wire on metal case, put other end of wire In outer hole, when the phones screen cuts off pull wire out of outer hole and quickly put it back in outer hole. I tried the instructed way for 15 minutes and got nothing. Tried it the way I listed and it worked first time and I wiped a ton of sweat off my forehead lol. Good luck
