I was in the midst of upgrading my BB 7730 to OS4, and the installer failed. (some general error about having a problem backing up files). Got an hourglass on the BB, then an error: JVM ERROR 523 and an option to reset. I reset, and it starts the entire process over. Sometimes, more often now than not, I click the reset option, and it takes me to another page saying JVM ERROR 523, and that has a different, larger reset button, but clicking that does nothing.
I've tried the javaloader -u wipe on it, but it cannot open the port. I've tried to use the application loader, but it cannot detect the blackberry on the USB port. Am I looking at a dead BB?
