Hello, agimur!
Unfortunately, I think that this recovery works only on Smart Prime 6 devices.
You can try it on your Tablet, but I don't recommend it strongly!
Backup your stock recovery.img in case of not working TWRP.
If I owned Tab Prime 6, I could compile a TWRP recovery for it..
Or send me your stock recovery.img and I'll try to build TWRP for you.. but there is a very chance of bugs..
So if you will send me your stock recovery file, I'll send you TWRP recovery build for your Tablet.
And if there were bugs, you'll report them and I'll try to fix them.
As I told before - If I had this Tablet it will be much easier to fix bugs and compile 100% working recovery..
Thank you for your feedback!
