9720 Device not connected to Blackberry server



I use a blackberry 9720...on Dec 18th, 2013 it had a charging port problem, as it was still under waranty, I took it to the store where I got it (SLOT, Lagos-Nigeria). After days of waiting, I finally got it back yesterday , 9th Jan, 2014.


Its workking fine now, just that its not connected to blackberry eventhough its registered to the network (MTN-NG)., there fore I cant receive push  mails and all the apps aint connected. Really frustrating! Smiley Sad


What can be the problem? How can you help me? My PIN is 2B49E945.

Re: 9720 Device not connected to Blackberry server

My father in law is having the same issues with his Bold 9900. Mine is the exact same phone but works fine. All the settings are identical except on mine the BB symbol shows up between the wifi symbol and the strength bars in the top right corner. He's really frustrated because we're on vacation and he can't get any emails that he needs to get. Weird.

Re: 9720 Device not connected to Blackberry server

Hi and Welcome to the Community!

With a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):

1) Register HRT

  • KB00510 How to register a BlackBerry smartphone with the wireless network
  • Please wait for one "registration" message to arrive to your Messages app

2) Delete and Resend Service Books

  • KB05000Delete the service book for the BlackBerry Internet Service email account from the BlackBerry smartphone
  • If you have no CMIME entry, then skip the deletion
  • KB02830 Send the service books for the BlackBerry Internet Service
  • Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.

3) Reboot

  • With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
  • See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

Hopefully that will get things going again for you! If not, then you should try deleting and re-adding your configurations for the affected email accounts. Otherwise, you should contact your mobile service provider for formal support.

Good luck!
