Reloading a Samsung Galaxy Tab 3 10.1

Hi everybody,
Got directed to this site for being my best chance of getting my Tab 3 10.1 (GT-P5210) back up and running. Worked on plenty of computers but haven't done much in the way of tablets.
The issue I'm having goes like this:
-When connected to a charger I get the battery icon with the circle. It does not reflect that it is charging. I have gotten a new battery for it and it still does the same thing.
-When the tablet is powered on it gets as far as the Samsung Galaxy Tab 3 10.1 screen.
-I went into the recovery menu (volume up & power) and did a factory reset on it. The background shows the Android laying down with No Command underneath and then shows Error!
-Downloaded the recovery firmware (I believe that's what it is) from Sammobile. 2.28 GB file unzipped, titled P5210XXUBNK2_P5210XACBNK2_Home.tar.md5. Copied it to a microSD card and tried the update from external option. Basically got the same result as before.
-It was suggested that I root the device, so I downloaded Odin and used TWRP (I think I got the right one). It did it's thing and restarted but I'm still no further ahead.

Is there another step I should be taking? Or other files I should be using?
I haven't found and clear tutorials on this so far, a lot of the ones I've come across have links to other forums that are about as clear as mud or have dead links.
My goal is just to have a functioning tablet at the end that works basically the way it did when I first got it.
Thanks in advance!
