You check manual in settings then update?
I wouldn't worry too much for that small of a update , as that tablet and android version very old to mater much.
4.4.2 might be the current oldest version of Android supported, and is likely to be dropped soon anyway, I don't think I would put much effort into trying to get that working anyway.
I merged your threads. You need to register if you want to carry on a discussion -- otherwise, you'll just have to keep creating new threads, which is inconvenient for everyone involved.
See my previous link -- that model didn't get any official update above 4.4.2.
