[Q] [Sprint version] Several questions from beginner to connoisseur

Hello everyone. Please help me to update software for my Galaxy Tab for Sprint. Update from the menu is impossible since I is not in your network.
I know that all the devices from Samsung have a file system rfs. Galaxy S is upgraded to a new and faster systems ext4 or yaffs2.
1) In our phone is possible?
2) What is the quality of custom firmware users?
3) How to update the software on our version?
4) What is the latest official firmware?
5) Should expect a full 3.0?
6) In the custom firmware is a hardware DivX / Xvid?

Is it safe to Install the International Stock Android version for the Note 8?

Hey, everyone!
I just received my Galaxy Note 8! I pre-ordered it and my carrier (Telcel, from Mexico) gave me a DeX Station as a gift.

The thing is, when I turned it on I noticed the Android version that was installed on it was the one butchered by the carrier with a lot of extra stuff I don't want to have on it.
Is there a way for me to install the International Stock version on my phone?
And, which version should I install to have the best experience without any carrier sh!t installed on it?
Thanks.
P.S. I own a SM-N950F, Exynos, 128GB Note 8, btw.

my SAMSUNG NOTE 8 BOOTLOADER AND ROM IS DIFFERENT ! I NEED HELP PLEASE SOLVE THIS . I NEED TO UPGRAGE ANDROID 7.1.1 TO 9.0 HOW ?

Did you buy your phone on Ebay or similar site? It seems your phone is made up from different variants put together to get the phone working. Flashing stock filmware or even trying to root and flash a custom rom could render the phone useless.

is there any solution ?
