Step-by-Step Instructions
1
NOTE!
Turn off the phone.
Remove the battery cover with your fingers.
Slide off the battery cover in the direction of the
arrow as shown in the picture.
2
Remove the battery from the phone with your
fingers by using the tab (1) in the lower end of
the battery and lift it up.
NOTE!
For the next step you need a flat 2mm screw
driver with rounded corners. You easily make
the corners rounded by using an iron file or
some sandpaper.
It is very important that you make the corners
round so you do not damage the Frame when
removing the Antenna Cover.

picture
Place the Guitar pick between the frame and the
front right next to key 3 and 6 as shown in the
picture. Slide it along the side from No.1 to
No.2. Pay attention to the angle of the Guitar
pick in the picture.
Once the right side has been released the front
