Right sounds to me like you have damaged the hidden sector. A retattoo should work. The procedure is here

but I would strongly suggest giving PC Servicecall and ring on 0870 9013000 and they will run you through it step by step and give you the password required at the end (I can't give that out publicly, PM me or nffc if you want to do it without their help).
