Blackberry - 9900 trackpad solution

BlackBerry Hardware Repair - GSM-Forum - forum.gsmhosting.com
if you have a problem with the trackpad try this solution:

1: replace trackpad

2: sometimes touch screen creates a problem so replace LCD

3: reflow or replace keypad connector

if still not work

4: Turn on the phone with an attached keypad and make a short circuit between the ground and the L1904 for 1 second (I am using tweezer) , the phone will turns off, remowe the battery and put it back to turn on the phone.

This solution it work for me on 100%
