Hi George,

nice to hear and i hope your phone works well!

Dominik Schnabelrauch -

Thank you for an excellent guide! Clear instructions and great pictures. I followed the steps and it worked flawless. One comment regarding Step 4 - I had greater luck opening from bottom side up rather than from left to right.

Thanks for the great guide! It took some effort to open the phone and to remove the old glue. Also with my old eyes (60 years) I could hardly see the tiny screws an connectors, even with my reading glasses on so it took me 2 1/2 hours to finish, but succeeded after all! Never did this before, so it is doable without experience, but you do need the tools. A looking glass would be helpfull too :)
