What to do if you encounter JVM Error 102

Encountering a BlackBerry error can be the most frustrating experience. Many of us rely on our devices, and to have it down even for a day can be a catastrophe. When you see an error message, you know you’re in for some pain. They don’t just appear for no reason, and oftentimes it’s not something you can fix yourself. Take, for instance, JVM Error 102. The blackberry.com description claims that, “The only recovery method is to wipe the device and restore a new system.” Yikes. That means you have no chance to backup any of your information. Gone are your applications, your emails, your contacts — everything. Thankfully, it appears there is a workaround for this one.


To perform this fix, you’ll need to download JL_Cmder. We discussed this PC application when we went over error code 552. You can find the app at blackberryfreaks.com. Once you have it installed, connect your device to your computer via USB. Now you’re ready to dig in.

Once JL_Cmder is up and running, select option 2, the event log. This should reveal the source of the problem. Once you see JVM Error 201, look at the line above it. That should contain the file name of the offending application (if you need some guidance, it should look something like this). Write down this file name and have it ready for use in just a moment.

On your PC, go to Start and select Run. Type cmd into the field and press Enter. Once you get your command prompt, you’ll have to change to the directory in which you loaded JL_Cmder by typing “cd C:\Program Files\JL_Cmder\” or whatever directory you installed it to. Once you’re there, type in the following string:

javaloader.exe -u erase -f FILENAME

Of course, you’ll replace FILENAME with the name of the file you wrote down earlier. This should take care of the problem. Disconnect from your PC and reboot.

If this works, I strongly advise you to backup everything, wipe the handset, and do a fresh OS install. The last thing you want is to face the same situation again in a few days.

Thanks to BlackBerry Support Forums contributor Shmoo for the tip. It’s an invaluable one.
