[help] Ipod stuck in boot cycle won't boot up to lock screen

After I installed bytafont and respringed I cannot boot up to the lock screen instead it looks like it will boot into safe mode and just stay there. It shows up in itunes with the ipods name and everything while it looks like it is stuck trying to get into safemode and just restarts after 5-10 minutes I don't know what to do and I'd rather keep my jailbreak.
