curve 9300 problem

hello every one,

my device is Curve 9300.

recently I got a problem with the network. so it is:

after start the device everything runs well. but a moment later, all the softwares which use the internet (both mobile and wifi) say "network is not available, please try later". only the blackberry browser still works, I can surf the internet with it without any problem.

I have tested the sim card on other devices, it works completely normal. so it's not sim card problem.

then I have updated the system and re-install the softwares, but the problem happened again.  I deleted all of them, and installed every single software and tested, it still happened.

so what kind of problem can it be? and what can I do to solve it?

help me!

Thank you all!

Re: curve 9300 problem

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) Resend Service Books (pre-BB10 devices only)

  • 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

  • Pre-BB10 Devices ONLY. 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.
  • BB10 Devices. Hold the top button down until the counter reaches zero. Wait for the device to be fully shut down (e.g., nothing at all displayed on the screen, no LED lights, etc.). Hold the top button until the red LED is lit. Wait through the full boot-up process. IF this fails, you can attempt the battery-pull method above, but it is normally NOT recommended unless nothing else works.
  • 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 I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.

If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.



But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.

You may also need the use of these tricks:

 

Otherwise, you should contact your mobile service provider for formal support.


Good luck!
