No this is not possible. If a phone is blacklisted, several bells should go off in your head. If you bought it blocked from someone, take it back because it is useless. If you took it from someone take it back with a huge apology. If a phone is blacklisted with a network carrier, then the phone is blocked on the Blackberry Server (RIM) Only the owner can have the handset unblocked. For this the original case reference number\ in most cases a Police case number. Proof of purchase and proper identification is needed So think again -Why is the blackberry handset blocked?

Frozen how? You can't open it ? Blackberry can do this sometimes if you drain the battery completely.. you must leave it plugged in until opens. Or, you can try a hard reset doing this:

1. Perform a hard reset to wipe all data from the BlackBerry Classic.
2. Open BlackBerry Link on your computer.
3. Connect the device to your computer using the USB cable.
4. Select your device on the left pane.
5. Go to "Back Up & Restore" > "Factory Reset" (Windows) or "BlackBerry Link" > "Preferences" > "Reload" > "Reload" (Mac OSX).
