My OnePlus One is really messed up. Anyone want to walk me through fixing it?

[AC Question]

So i factory reseted my Oneplus which was running Euphoria OS and the setup Wizard kept crashing. So i went to my recovery and restored an older OS. CM 12. The phone would be stuck in a bootloop unless i was plugged into my computer. If i unplugged it the phone crashes and returns to a bootloop. I have tried flashing numerous roms that i have used in the past on this phone and i keep getting error messages. Thanks for the Help

Do you have a nandroid backup of the stock ROM?
