Question about RIM BlackBerry Pearl 8100
The rollerball only moves up not down, please help
Your rollerball needs a clean.
The silver ring which covers the trackball can easily be removed if you use a small screwdriver to lift it at the outer side of the ring. Be careful here! Like you should be during the whole process as all parts have very small plastic nipple which can break very easy. When the silver plastic ring is removed you will see the inner trackball component which can be removed completely. Before doing this you should carefully remove the silver metal ring that holds the trackball component in its position. The trackball component itself can also be carved. For every direction the ball can roll to you’ll find a sensor wheel. Those wheels are mostly carrying some gunk you should clean them from. Once this is done put everything back together to the place the pieces came from and secure the trackball with the silver plastic ring you removed in the first step. Your BlackBerry’s trackball should be back working now.
There are pictures of how to do this on "other" forums.
