Just finished mine. Went to Home Depot to buy the Torx tool. Got back and my 450 has phillips head screws. Took it all apart. Put in the screen and digitizer but had problems with the cables and connecting them back to the terminals. Also one of the 8 black screws just did not seem to go all the way in. Turn it on and calibrated it. It works like new but I always worry about electronics and me screwing with them. I will be keeping my fingers crossed. Yes the screen seems faster. Thanks goodsupply.
I took the road less traveled and it has made all the difference
