Quick Question...how do you wipe an 8700r? Because my device is hanging at 88% and I cancelled the activation. Now I don't know how to reactivate it on the BES?

Background: I have a brand new 8700r (previously I had a 7290). I attached the 8700r to my computer and it automatically try to do enterprise activation. It hung at 88% and got mad and cancelled the activation. Now I don't know how to reactivate it? Does wiping the device retrigger the activation?

Please advise....getting frustrated.

Thanks,
