770i 'configuration error'

[senter]

Hi all,
Spent some time trying to unlock my 770i (db2020 cid 52) using the tutorials on the forum. the phone is now saying on startup that there is a configuration problem and to contact the service provider. Can someone give me some pointers to either repair the phone or get me back to where i started? To be honest I'm lost as what to do:confused:.
Thanks
