Ok so this is my first post, pardon if this has already been answered but I doubt it.. here is what happened. Well I was working on my brothers car and left my phone on his spoiler and he went for a test to see if everything was working OK. I forgot to take the phone off of there and noticed 15 mins later, I ran down the street and found it in three pieces (battery, cover, and main phone) the screen was cracked up and I could only see about 1/3 of the screen, about four days after that my screen stops working completely. So I ordered new parts (LCD, Digitizer w/ housing, and a extended battery for the hell of it). Once I got all the parts I took the screws out, but was stuck for a couple days w/ a stripped screw that eventually came out like cake when I tried on the day I put it together. So.. I took it all apart and got down to the digitizer and old LCD w/ old faceplate, I took the LCD out and put my new one in after cleaning the back of the LCD and are where it rest on, so after I put it together and was carefully done making sure not to break anything and have the ports connected all the way, I turn on my phone and to my delight I can see my screen again but knowing my luck it wasn't going to be that easy, so when the lock screen came up I tried to put my pattern in to my surprise it was unresponsive and I've taken it apart a couple times to make sure all ports and surfaces are clean, but still it doesn't work. I really don't want to have to go to a repair store and them charge me an outrageous price when I just bought these new parts so that it would work. ALL HELP IS GREATLY APPRECIATED.
