Hi Rob,

Reset, you mean firmware reinstall. Download the latest firmware drivers from and then install those drivers via the Desktop Manager on your PC.

I hope this helps,

My blackberry is saying jum error 513 reset,how


Go to the blackberry site and download the blackberry desktop manager. After this must have been downloaded on your computer, please run it and open it.

Connect your blackberry to your computer and initialize the Blackberry Desktop Manager and it would show connected once it is connected to your blackberry. You can click on the menu and go ahead to click on add and remove software to reinstall you device software.

This would resolve your problem.

JUM Error 102 Reset

Sorry to hear that happened.One of the operating files has become corrupt, which sometimes happens with Blackberrys. If you go to and search KB11320 and KB12532 you should be able to fix it yourself. The steps are long and involved or I would type the solution here for you.
