From Pinstacker JTReeves:
You should be creating a backup of your device data regularly, e.g., as often as you update your calendar and/or phone book.
If or when you get a JVM Error 102/Reset message, do the following:
1. Connect your BB to the computer.
2. Run JL_Cmder
3. Choose option 5, wipe the device. This will delete all files - OS and data - from your BB. The BB screen will show JVM Error 507. This means the BB has no files installed.
4. Using Desktop Manager, reinstall your software. When you run the Application Loader, check all the available boxes.
5. When this process completes, restore your most recent backup file.
You should be back to normal, with the exception of having to reregister OTA or other 3rd party apps. Save their reg numbers in your Memo app so that you have them handy.
