You may be able to do a factory data reset.

To do a hard reset or data reset, enter using Dial pad 3845#*620#. From menu select factory reset or whatever you want.

If you can't get to the dialer, you'll have to grab the stock RUU and flash back to stock, first going into the Eve recovery menu to wipe cache, etc.
