What are - JVM error Codes
Here is what it says for JVM error 102...
102 - Invalid code in filesystem
The system has checked the .COD files in the handheld for modification, and determined that there is a problem with one or more .COD files.
If all loads fail, it could indicate a build process error where there was a problem signing the codfiles.
If some user action to the device caused this problem, the reset cycle will be continuous since the code in the filesystem has been corrupted. The only recovery method is to wipe the device and restore a new system.
