I have gone through 4 touch pro's! Mostly the same issue! I have just realized what the problem was.... Dashwire! My keyboard would stick and the backlight wouldnt come on... and it has taken me since the begining of February and 4 phones to figure it out! If you are having problems with your keyboard working and you are using dashwire... simply un install it!! it will solve your keyboard issue! It has fixed mine and my nephews phone!
