Do I need to root device for official firmware?

Hello,
I want to update my Galaxy Tab 2 GT P-5100 to Jelly Bean, but since my carrier locked it at 4.0.4 and removed the dialer, I want to flash new firmware from other country, but I need your expert help:
Can I flash firmware from country which is not mine?
Do I need to root my galaxy tab if I am going to flash official firmware? (I am going to download it from SamMobile)
Thanks

This phone doesn't have the official update to 4.4.2 Kitkat.It's reall old so that's why Samsung won't make and Android 4.4.2 for S2.But you can look for custom 4.4.2)

if you want to get back to 4.1.2 go here http://www.sammobile.com/firmwares/1/ download whatever country you live in, and right below the download page should be a guide on how to use the file. its pretty much like when you first rooted it.

I searched on sammobile and it shows version as 4.1.2, which is exactly what I have. I need to upgrade to a newer version.
