Hello guys im having a bit of a difficult time and any help is greatly appriciated.

Ive upgraded my OTB 1.0.2 phone to 1.1.3 succesfully. My friend asked me to upgraded his as well (OTB 1.0.2). I first loaded i.unlock.no's virginizer pack in installer and virginized the phone. once upgrading to 1.1.1 i attempted to use jailbreakme.com method to jailbreak. but after i got into pref://1f the wifi and bluetooth was greyed out. I attempted to restore 1.1.1 again but still greyed out. I then attempted to downgrade to 1.0.2 but error (1) appeared.

Thinking it was due to itunes 7.6, i tried downgrading to 1.0.2 using itunes 7.5 and 7.4 but still error (1). I using the CARNAVAL method of downgrading (apptap, carnaval package, PACAY, etc.)
