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
