Very flawed guide - there is no way to use the pick to start the removal of the digitizer. Ridiculous to think that the suction cup and heat will do anything useful. Further, the lack of explanation and correct detail for the Cellular model resulted in the ruination of my device - karked the cellular module because they lack the documentation for it. Karked the digitizer because again, detail wasn't correct. Wasted money, wasted device. i think the guide was pretty bad at explaining where you can actually go and where you can actually not go. It was also terrible at explaining how to reassemble with the adhesive.
