need info to unroot my samsung s5

I have the g900h s5 device that I rooted a little while ago. I want to unroot the phone.

when I search for my firmware, I am getting confused by the country codes I see on the files. does the country code matter on the firmware?

when I do the *#1234#, I see:
ap: g900hxxu1ani1
cp: g900hxxu1ani1
csc: g900huub1ani1

on sammobile I search for g900huub1ani1 and I see 3 countries listed.
Trinidad and Tobago, Uruguay, panama
which one do I choose? does it matter?

The place you bought it from. They know which phones they bought and, if they keep good records, which particular phone they sold you. As I said, you could try any Latin American Spanish ROM (I doubt there's a Latin American phone with an English ROM), but it could brick the phone until you flash the right ROM.

when I run the software update on the phone it is saying the latest version is already installed. before it was giving me that error about the software being modified...

basically I want to do the over the air update to the new android, that is the only reason I actually care to restore the phone. from it giving me the msg that the current version is installed, does that mean it will update to the new android when it is available for the g900h devices?
