App error 603 after updating Blackberry messenger

 Hi

 

I updated Blackberry World and Blackberry Messenger simultaneously. After rebooting, the phone goes on, does 'software security verification' then shows me a white screen that says 'App error 603' Reset'.

 

I got it to work once (I don't know how) and then I couldn't get into Blackberry messenger - I tried deleting it, but the phone wouldn't give me the option. Now it just constantly goes to the white screen:smileysad:.

 

Anyone know what I could try?

 

Thanks!

Hello Samantha77

 

Welcome to BlackBerry Support Forums

 

Do you have a backup of your device ?

 

You can refer to this Knowledge Base to resolve your issue :

After recovery , If you have a previous backup or using BlackBerry Protect then you can restore your data from there.

 

Additional Information :

KB23951"Error 603", "App Error 603", or "JVM 603" appears on the BlackBerry smartphone
