I bought a phone on orange from someone and had it unlocked to 02 network and as I wasnt using the phone I sold it to my friend however she tried to update it and wiped everything from fone, I no longer have original SIM card...gave my friend a grudged refund as it was her mistake, but now I'm wondering if I can get handset back to original state or atleast working again?? As now left with a handset that does nothing.
