Question [Q] No Service/Network?

Hi all Trying to help a mate with a phone he bought, He said there was no network service so I asked him to drop it off to me. I have tested it with my sim (EE) and I get no network service too. I have checked both IMEI numbers to see it is blacklisted/ blocked and it doesn't appear to be, they are both the same but for the last three digits 001 and 019 respectively. the 001 is the one that is shown on the back of the battery.

The version infos is as follows:

Model Number: P780_ROW

Android Version: 4.2.1

Baseband Version: P780.V20,2013/07/31 10:51

Build Number: P780_ROW_S115_130807

The phone appears to be in very good condition, it looks brand new. If the SIM is placed in the 3G/2G slot Slot 1(the slot nearest the red reset button, the SIM isn't seen, if its put into the 2G sim slot the SIM is seen and under SIm Management I can see The SIM Network Brand ie O2 -UK, the phone number of the SIM and Data Connection is in black but messaging and Voice Call are greyed out and faded.

The default language is English US so I am assuming this is a US phone because there are no other languages available.

I have tried a factory reset, a soft reset and looked at a hard reset but when it goes into the menu for hard reset the menu is in what I think is either Chinese or Taiwanese, well its definitely oriental so unless I known the sequence the menu is in I can't really chance screwing it up, plus the menu order may not be the same as in English.

Any help would be great
