ballsed xbox soft modding

Hi all, looking for a little help, recently soft modded my ratail v1.1 xbox.
All was going well till I selected unlock hard drive & restarted it.
I now get the xbox service screen flashing error code 5.
I have done a bit of looking around & found that this error code is popping up because retail xbox's don't like the hard drive being unlocked.
I didn't get as far as connecting the xbox to the pc so I can't access any menu's that way. Took the hard drive out & formatted it in my pc as a lst resort, but that has made no difference.
I'm thinking it's completly fecked.
Any help appreciated

cheers
