With one hand, push the rectangular button located on the back top-side of the phone.
With your other hand, remove the rear cover.
Remove 5 screws, 1 from each corner of the phone and 1 from the center-right of the phone.
Now pull off the rear casing, using an opening tool. **Buttons for volume and pictures may fall out**
Hold the circuit board and turn the phone upside down.
Then let the circuit board hang down so you can disconnect the ribbon by getting under an edge and popping it off. **the rubber keyboard may fall out**
Once the circuit board has been removed the rubber keypad will be visible. If it has not fallen out on its own it can simply be peeled out. It is lightly attached like a sticker on the top three tabs. The left most table is labeled “B”, the center tab is blank, and the right tab is labeled “N”.
