Please be aware that by opening your GSM you will loose your warranty on this phone. I am not responsible of any damage caused by opening the phone.
Remove the backcover
Remove the battery
Remove the SIM
Use a TORX 7 (yes I know, this size is rare) to unscrew the four visible screws.
As you might have noticed is that the phone still does not open, because one screw is situated below the typenumber label. Remove the label (hard), or try to locate the screw and unscrew it through the label.
