Is it possible to go back to a prior update of Cynagenmod?

[AC Question]

I have a Verizon Note 2 with Cyanogenmod 10 and hit an update that was 11 or 12 by accident. My screen now says Team Recovery Project. I've tried rebooting and restore but go back to the same screen. When people call you mail app send the call to my email voicemail so I think phone is still working at some level but cannot call or save my contacts. Is there a way to go back to mod 10? Anyone in the Boston area able to help me? will Verizon be able to transfer my contacts if I buy a new phone or will I be able to restore from google to another android device or Apple (Not really enthused with iphones)
