hard resets return the phone to how it was when you bought it.the easiest way on the pro is to go to settings>system>clear storage and enter 1234 and press yes.i think your issue is something is wrong with the rom you downloaded.it might not be stable.i downloaded the new opera and it crashed my phone.others have it and it works fine,so sometimes it's just your phone.hard reset and exchange it and see if your new one can handle the new rom.if not,you might want to stay away from that rom.
