This not-so-old phone has developed some problems and I wish to rule out software issues.

I need to un-root it and flash back the Samsung official firmware. Google guided me to HERE (http://visihow.com/Unroot_Samsung_Galaxy_S4_by_Flashing_Official_Firm ware).

Of course, first is to download the official firmware from here (http://www.sammobile.com/firmwares/database/GT-I9505/TNZ/) but I am confused as to which is the correct one to choose? In the top left box, there are :

New Zealand (TNZ)
New Zealand (NZC)
New Zealand (Vodafone) (VNZ)

Originally, this was a 2 Degrees phone.

Which should be the correct one to select?

To figure out which one you use:

dial *#06#
for your IMEI number, write it down.

then dial
*#272*<IMEI NUMBER>#

replace <IMEI NUMBER> with the number you wrote down.

This will hopefully give you the CSC and tell you which one you need.

I think you need a better guide, the one you are following, not giving you key things possibly to ensure you get the phone back to an untampered state.

Oh and if it doesn't work, NZC is generic and usually used for 2degrees

Yeah, I would probably agree with whatever it was he said.
