Blackberry Curve 8330

We did not have an actual back cover or battery for the phone we were given. Therefore, the first couple of steps will be without pictures. Hold the phone with the back side facing you. Press down on the silver tab towards the bottom end of the phone. Carefully lift up the back casing to reveal the battery.
Put your finger on the top left corner of the battery and lift the battery up and out of its housing. The phone should now look like this.
Remove the two top screws using a T5 Torx screwdriver.
Use a plastic opening tool to pry the edges of the bottom cover until it snaps loose. The cover will now pull off easily.
Use a plastic opening tool to pry between the front and back cover. Start prying from wherever it is easiest to separate the silver and black plastic of the covers.
There are 5 securing clips on the front panel to disconnect.
Pry gently to prevent breaking the plastic clips when removing the front panel.
Once all the clips have been freed, the front cover will lift away from the phone.
Lift the flexible keypad away from the device. It should come off easily.
Use a T6 Torx Screwdriver to remove the four corner screws on the keyboard's housing. Lift the keyboard frame away from the device. There may be a small amount of adhesive at the bottom of the frame that needs to be pulled away.
Detach each side casing by pulling them off gently from the phone.
Remove the back housing from the mother board. Unhook the screen frame from the small tab at the top of the motherboard.
Using a plastic opening tool, detach the connector on the LCD screen from the motherboard. There may be some adhesive behind the LCD screen. If needed, pry the LCD screen away from the motherboard using the plastic opening tool. Remove the LCD screen from the motherboard
Once the LCD screen is taken off, the motherboard is fully separated from the device. The picture shown is the back side of the motherboard.
