When i turn on it reads JVM 513 RESET

Hello. Download and install Blackberry Desktop 4.7 on your computer if you don't have it already. Then connect your phone WITHOUT battery to computer while running Blackberry Desktop. Select App Loader and then Software Update. Follow directions. THE 1ST TIME UPDATE WILL FAIL. Then insert the battery in the phone and you should get Error 507. Then redo the above with the Battery in the phone and all will be ok. Please post if you need more help.
