DISASSEMBLY

AFTER SCREWS HAVE BEEN REMOVED, SEPARATE FRONT AND REAR COVER BY
FOLLOWING THE STEPS BELOW :

Note : All used screws are not recommended to use again. Brand new screws should be

applied for assembling.

1. Rear Cover(R)

Step 1

SLIGHTLY LIFT THE TOP OF REAR COVER(R) TO EXPOSE A GAP BETWEEN REAR
COVER(R) AND FRONT COVER(R).

Step 2

INSERT SIM CARD OR THUMBNAIL INTO THIS GAP, THEN SLIDE TOWARED TO THE

HINGE UNTILL THE COVER POP APART.UNCLIP OTHER SIDE.

Step 3

LIFT THE COVER AWAY VERTICALLY FROM THE TOP.

2. Rear Cover(M)

THE PROCEDURE IS SAME AS FOR REAR COVER(R)

Dissassembly is done in reverse order of assembly.
