Everything in this guide looks pretty good. The only thing I would add to step one is to make sure you remove both the SIM card and the Micro SD card. Failure to do so can result in a broken SIM/SD card, slot or board they are connected to.

Worked great! Would have been better if I had the pry tools though. I am getting them next week :}
In order to open, I did not want to purchase a pry tool so I used a think screwdriver to open abit and inserted an old credit card that made the job without danger.
How do u find the tool to open it

NOTE: Make sure to remove both the SIM card and the Micro SD card prior to disassembly. Failure to do so could result in broken parts.
