    Default 8520 Cannot disconnect calls

    Hi,

    I have a Vodafone Canada Blackberry 8520. Its quite old and has been unlocked. I recently updated the OS using the Blackberry Desktop Software. After the update, the End/Power button has started acting weird. I cannot disconnect calls. If I try to make a new call, it says call in progress. I cannot switch the phone off by holding the Power button. The Power app does not respond either. Right now I'm trying to downgrade the OS and see where this goes. Any advice will be very helpful!

    Thanks!
