1st of all thank you. you are the 1st person ever that botherd to answer...something. (so i apriciate it).
You are most welcome

what if ill be able to root with something like KingRoot?
I'm not sure...since you're running 4.4.2, you've likely got other options besides KingRoot that you could also try, although I can't specifically recommend one that will root your tablet.
would it be doable (to creat a "custom recovery")?
i can root using Kingroot but i rather root via Boot.
so maybe ill start with asking about custom recovery.
i dont know much about android but i do have some skills on computers.
can i guess that "custom recovery" is something like a... "backup sys file"? a file that contain a snapshot of the OS and its config?
Can i creat this file on my own (if im rooted?) _ if yes then is it simple?
thank you very (very) much. (iv been asking this over the web for 8 days now and you were the only one to answer.)
thank you and sorry for my eng expression.

You're wise to be ware of apps or methods that don't come from well-known developers--rooting by flashing Chainfire's SuperSU*.zip package is the "safest" and most straight-forward--although admittedly not an option for a lot of devices without a custom recovery.
A custom recovery is a tweaked ("custom") version of the stock recovery software that gets installed and lives in your device's /recovery partition. Every Android device has a stock recovery partition and it is sometimes possible to overwrite that partition with a custom version. That custom recovery software is where Chainfire's SuperSU*.zip package is installed/flashed.
Unfortunately, you've got two big hurdles in doing this:
1. Have a custom recovery that's built specifically for your device. This is a non-trivial task and typically requires a developer that a) has access to that device or the core/key files they'd need to build the recovery, b) knowledge and the tools for building/testing/debugging the custom recovery. You should NOT use a custom recovery built for another device since the hardware components and partition maps are likely different and you'd risk a soft or hard brick from any flashing operation.
2. If you do happen to find a custom recovery built for your device, you'd have to be able to flash or launch the custom recovery--and if your device has a locked bootloader, this may very well be impossible.
So, all of the above being said, your best bet might be to find other devices that are similar to yours (Android version, CPU, hardware setup) and start researching for rooting options that work on those devices.
Unfortunately, I also don't see a lot of information out there from a Google search about your device...you're not alone, there are literally tens of thousands of different Android devices that have been sold throughout the years and only a small percentage of them have a robust rooting and developer following that make what your asking "easier".
Best of luck to you
