Why can't I upgrade my Android to Nougat (7.0.0), Marshmallow (6.0.0), or Lollipop (5.0.0)?

[AC Question]

My device is Samsung galaxy tab 3v SM-T113NU.

Goal: 4.4.4 to 5.0.0 +
When I try to upgrade, it says "You already have the latest update", but I still have 4.4.4.

I'm Expecting 5.0.0 +, but it wont work.

Any tips for me to upgrade?

Sammobile... Software... Type in model number and the latest software will be there

Repositories like sammobile only have official, Samsung stock ROMs, there won't be anything there that your carrier doesn't already push to you. If you want to upgrade your Tab 3 to a newer version of Android, you have to root it and re-flash it with a third-party ROM.
