Help getting phone to work again!

Guess I'll start at the beginning so nothing gets left out. I was rooted on OC1, downloaded FlashFire to update to OF1 . Flashed it, the phone rebooted and got stuck on the black Samsung Custom screen. I've tried to flash tar files of OC1 and everytime I put it or any kind of tar file in the AP slot of Odin, Odin becomes unresponsive and closes. I tried to load up the SD Card with OC1 and OF1 Roms and tried to flash those to see if that would do anything. The phone always says (in recovery at the bottom of the screen)- Manual mode, applling multi-csc...applied the csc-code-vzw. Then says below that, remove failed file '/system/csc_contents'(read-only file system. At the top it says Android system recovery so I'm assuming that's custom, I know its not Safestrap so I guess its FlashFires recovery? Anyway, when I try to flash a ROM it says,E:footer is wrong E:signature varification fail. I'm at a loss as to how to get the phone back, if its possible. I was always told that if the phone powers up, its recoverable, just not sure how. Any advice would be awesome, I've been messing with this thing since early yesterday and I really need my phone back!
