Connection Error! Message: 0x89731812

I have WP7 Mango 7720.

When I try to connect to the phone, get error: Connection Error! Message: 0x89731812.

By connecting the emulator normally!

That error usually indicates that the phone is locked, and needs to be unlocked to be able to connect. I'll be extending the recognition of some of the error codes that the CoreCon library spits out when it fails to connect so that that they are more descriptive.

Please let me know if this doesn't solve it for you - and we'll look at other options.

Strangely, checked the lock was removed. Now, a different error: 0x89740005.

When the phone is locked, an error: 0x89740006.

Good luck!

Do I need to do a phone Jailbreak ChevronWP7, so you can cast the program on the phone?

No, it simply sounds as though your phone is not developer registered. Make sure to register it correctly (and that it's running Mango) and you should be good to go.
