I have a Nokia 6111 locked to Tesco UK; I've tried two times to unlock the phone with out luck. Now I have read your posting and you say a phone that shows: CANNOT UNDO RESTRICTION , it is unable to be unlocked. Can you clarify this? Is there some cable or hardware solution that can be implemented? Nokia 6111 IMEI: 359364005622920 TESCO UK Thank you in advance.
If you tried twice already and it didnt work , you could bring it along to an unlocking shop/market and they might be able to do it for you for a small fee
