Just keep rolling the pearl while putting pressure on it. It may help to turn the bb upside down so that any debris will be "freed" more efficiently. It may take some time, but eventually the pearl will be moving again.

    I'm partly revising myself. If rolling the pearl under pressure doesn't work, you may have to replace it (I got it for $4.99, with shipping). Lift the silver ring around the pearl carefully with a small screwdriver (it is held by tiny prongs at the east, south, and west). If one of the prongs breaks (and they break easily), remove the remains with a pin. Turn the blackberry upside down and hit it slightly against the desk until the case with the pearl falls off (it's about a .25 by .25 inches). Put the new case in with the "stem" in the back (the contact when you click with the pearl) pointing south. With a bit of wiggling it will slide in smoothly. Put the new silver ring back in place. Be careful not to break the prongs (but if you do, two prongs will suffice to hold it in place). That's should be it. No need to even open the Blackberry or to be too much concerned about warranty. (Most likely, your warrenty is expired anyway when enough dirt has accumulated to permanently block one of the four small wheels at the corners of the case.)

Ball on blackberry wont navigate up or down

Hi. BlackBerry smartphone trackball fails to roll in a particular direction because, debris is lodged in the trackball.
The trackball user interface found on certain BlackBerry smartphones is similar to the trackball used in a mouse in a desktop computer.
Using for certain period debris comes in contact with the trackball and affects the usability of the BlackBerry smartphone, rapidly roll the trackball up, down, left, or right to potentially correct the problem.
If rapidly rolling the trackball does not correct the problem, please contact your wireless service provider for support options.
I hope this information will be helpfull.

The track ball moves up and side ways, but will not roll down at all


Please select Options from the Main Menu
then click on Screen/Keyboard
then scroll down till you get Trackball, just below that you will find
Horizon Sensitivity &
Vertical Sensitivity, please increase the numbers then Save and check the effect.

If you still face the same problem you need to take the Handset to the nearest Service centre and get it checked cause it could be the problem with the Trackball itself.

Thank You.

Blackberry 8330 trackball sticking

Your trackball has dirt or more commonly dust in it. You will have to roll it and move it around like crazy to get the dirt out. You can also try blowing while turning.

It is not easy to get it out but when you do it willl work just fine.

Got my trackball a bit wet and now wont work, what should i do?

You might have damaged some circuitry, but can try cleaning the trackball with alcohol and a Q-Tip. You need to roll the ball around with the alcohol-soaked Q-Tip, then let it try. This will have the nice side effect of helping drive off any leftover water, too.

Trackball fell out of my blackberry curve. I need to scroll down. Is there an alternative method?

You have to have the trackball, there is no other way to scroll. You can probably get one from your local phone store.
