can you help me?
So I had SIM unlocked at&t htc one (I obtained unlock code from carrier). Once I unlocked it, i was using european simcard and then revone s-off came out. so I s-offed it successfully and after reboot i got exactly same problem - enter sim imsi unlock code or something like that. Any code would result in unlock successful and reboot phone, but it would ask code again. I ended up sending phone to HTC for repairs. I guess they completely reflashed firware or updated something else, since phone that i received back had different IMEI then what i send them (same physical device though - scratches on the side). I had to obtain new unlock code for new IMEI and new code unlocked it for european sim.
