Re: cannot upgrade


I suggest that you clear the AppWorld application cache:

1. Open App World

2. Go to My World

3. Follow one (and only one!) of these steps:

3a. For keyboard-based BB's -- Hold down the ALT key and then press, in sequence R, then S, then T

3b. For Touch Screen Only BBs -- Hold the num-lock (!?123) button so it locks and then press, in sequence 3, then 4, then (

3c. For newer (e,g., OS6 and 7) BB's, see this KB:

    • KB24714 How to clear the BlackBerry App World cache

4. AppWorld should close.

5. If your BB locks after issuing the cache clear, perform a battery pull reboot

6. Return to AppWorld/MyWorld (it may be sluggish while it re-synchronizes).

If step (4) does not happen as listed, then the clear cache did not work.

Hopefully it'll work for you! Good luck and let us know!
