Root need info to unroot my samsung s5

[DaGoTTi]

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?

Hopefully a move here will get you some advice from other users of the Galaxy S5.

you need to select the country of origin of he phone, if in 1 country there are multiple version it depends more on which operator you are using and if your operator has a different firmware.
