    • Start by powering off the phone.

    • Next remove the sim card tray.

    • Once sim tray is removed you can now remove the T5 screw from the sim card slot.

    • Now insert the T5 screwdriver into the headphone jack. There is a T5 screw in the headphone jack that has to be loosened.

    • The screw in the headphone jack does not come out, so do not try to remove it. Nokia uses a lock bar on this case that locks the plastic clips in place. So the screw in the headphone jack is how you loosen and tighten the lockbar. You will break the back case trying to remove it if you are unaware of the lockbar and do not loosen it first.

  2. Now with the lock bar loosened you can begin using your pry tool to free the plastic clips that hold the back case in place. I find it easiest to start at the top left corner and work down to the bottom left corner.  Then move to the top of the device and work your way around and down the right side of the device. I then free up the bottom last.  Seems the guitar pick works great to free the plastic clips. Once the clips are free you can then pull the back case off.

    • Please use a plastic tool to pry the battery up rather than a metal tool. Just to be safe.

    • I did not have to apply any heat to loosen the adhesive under the battery. I did use some needle tip tweezers to get under a lip where a screw belongs, just high enough so I could get my plastic spudger under the battery.

    • Then work your way around the battery to free it from the adhesive. Beware that the ribbon cable is located near the camera so be careful when you get to that area.
