The problem was that my phone - just a little under 2 years old was shutting down completely at random. Sometimes when compsing a message, sometimes while in a game. I was also unable to play any games when the battery was below 50% on the charge. When i would attempt to do so, the phone would just shut off.
The repair went well, and was very well documented however the ScrewDriver supplied didnt fit the screws. The supplied screwdriver's tip was oversized and it requred me to use one of my own, an EyeGlass repair screwdriver.
You will probably need a screwdriver with a smaller tipped Phillips head.. An Eyeglasses repair screwdriver worked perfectly.
