Question RAZR brick??

So I wanted to do some theming to my stock ROM. Mainly the dialer, contacts and messaging apps. Everything turned out like I wanted, til I found out when I wanted to add a new contact the contacts app would crash...would not let me add someone. So, I went back into my recovery (ss 3.11) to restore the backup I had. I did so and found my phone in bootloop. So to be clear, stock ROM in bootloop yet I can get into my recovery and I'm running slimkat slot 1. I'm not too worried I can't get into stock but if I wanna run an older version of SS(to try different ROMs) I can't uninstall the version in stock slot. Any info or tips would be great. Thanks in advance.
