it becomes stagnant or gets hang up when I click bb app world in my device because of that I am unable to download any application. 

when I visited bb page and tried to download app world through 'send link to email, it sent me a link to my id and i opened it, but it showed "909 error" download failed.

Hi and Welcome to the Community!

Here is a KB that discusses that error:

  • KB29060 When attempting to install some applications, a 909 Authentication error message may be displayed

Hopefully it contains something useful! There also are multiple existing threads on this site that discuss that exact error...your review of those might prove useful, and a search of this site, using the error message, error code, or symptom, should reveal all applicable existing threads to you.

In addition, you can try this sequence:

1) Remove AppWorld from your BB

  • KB10040 How to view or remove installed applications on a BlackBerry smartphone
  • If it requests that you reboot the BB, do so

2) Do a Batt-Pull reboot (power on, remove battery, wait, insert battery, wait), even if redundant to the one you did in step 1.

3) Install (on your BB) a fresh copy of AppWorld

4) Do another Batt-Pull reboot

5) See if it now works.

Good luck and let us know!
