Default [Q] Htc One Swapping Roms Problem

Hello, I have currently trying to sim unlock my Sprint Htc One with little luck. I was currently swapping in between roms to find one that worked with firewater so i could s-off my phone. Somewhere in between i managed to mess up and now when i boot the phone i get HTC (quietly brilliant) then it goes to a purple screen with a ton of white small horizontal lines then it goes to htc one screen which it will still there for ever or until i turn the phone off. I am a complete noob at all of this and have slowing been understanding, please help!
