Welcome to BB Forums.

Most likely you will have to reload the handheld (BlackBerry) OS.

KB24395-"Error 523", "App Error 523", or "JVM 523" appears on the BlackBerry smartphone

What should I do with App Error 523? - BlackBerryFAQ

Look at the top of the Storm (9500? 9530? model numbers are easier to work with) for instructions on how to download and install the latest OS.

Please help my 8520 displays "app error 523 reset" on screen and refuses to start. I have removed battery severally to restart but it still displaying same error code. Please help
