My blackberry bold is just on , and the screen stays white saying "JVM error 51?" i don't know what's wrong with it.

Have you ever done a backup with the blackberry desktop manager?

If so, hook up the phone to the PC and restore it.

If not, chances are you installed something that caused this, so try your best to uninstall it.

When in doubt, turn the phone off, pop the battery out and wait 10 seconds before putting it back in and powering it up.

try to go into settings, there should be a setting somewhere in there saying power saver or something, turn that off if its not already. otherwise, there must be something wrong with the screen lighting , like its blown or something.

Blackberry pearl wont go past the white screen with the hour glas

the only thing that you can do with this issue is try wiping the software clean and reinstalling fresh software. You would need the blackberry desktop manager first installed on your home computer. If you dont have the cd the program is more then likely available on your mobile providers website. Once the program is downloaded and installed follow these directions

To perform this procedure, follow the steps below:
  1. Remove the battery from the BlackBerry device.
  2. Double-click Application Loader in BlackBerry Desktop Manager while the BlackBerry device is not connected to the computer.
  3. Click Next on the Welcome to the Application Loader Wizard screen.
  4. When the Communication Port Selection screen appears, connect the BlackBerry device.
  5. When the USB-PIN option appears, click Next. The Device Application Selection screen should appear.
  6. Re-insert the battery and allow the process to complete.
