There has been a lot of changes and fixes. You can look at them here https://twrp.me/ . I would always recommend using the latest version.

Having a bit of trouble with the drivers I believe, I keep getting device unrecognized in Windows, tried two different machines, same issue. Any idea what is wrong?
I am getting the same when in recovery mode and in normal Android OS.
I am not getting the popup that says Use USB to transfer files etc, it just says slow charging.

Error is Uknown USB Device (Device Descriptor Request Failed)

Install device drivers and adb/fastboot ones. Search here on XDA, I'm sure you'll find them :good:

I have installed the ones linked at the top of this post. Is that the reason why is happening?
Is it not strange that when I am not in recovery and just booted to normal android and try to connect to my PC it also happens?
Hooked up my Samsung phone and Odin picked it up instantly - thinking the usb port on the table is gone and is only charging now. If that happened there is no way to TWRP without it right?
I'll look for those drivers thanks.

Try these drivers and let me now if they fix your problem.

Also you can try cleaning your usb port with a small piece of plastic or a pin. They can get packed with dirt sometimes. Also try a different cable.

 

[sd_dracula]

Tried them too but it looks like the usb port is damaged and needs replacing

 

[sd_dracula]

Got my usb port fixed, OEM unlock in dev mode, ran odin along with the twrp-3.3.1-1-gtaxlwifi.img.tar file but it doesn't seem to work. Tried twice and this is what I get after powering on with Power + Home + Up Volume which seems like the default bootloader?
Odin completed ok too. Any idea why it won't take?

It probably is taking but getting immediately overwritten because you are allowing it to reboot into the system. When you flash TWRP with Odin, you need to click Option and uncheck the auto reboot. Then, after flashing, hold the Home, Vol down and Power buttons until the screen goes black. Then, VERY quickly switch from Vol down to Vol up until the Samsung logo screen appears. Then release the Power button while still holding Vol up and Home and the tablet will boot into TWRP. After that, you can reboot system and TWRP will remain as the recovery app.

Yup that did the trick, thanks
How can I make a full backup of stock OS using TWRP? Is it safe to restore from that backup in the future if needed?

You can't. The data partition is encrypted and TWRP can't handle it.

Ok so the only way would be to install the official ROM again right?

There are backup apks in Play Store. You just can't use TWRP. Typically, people install TWRP because they want to root and use custom ROMs. Before using TWRP to flash custom ROMs, you must first format the data partition to get rid of the encryption. But that erases EVERYTHING on it. Including any saved video, audio, pictures or apps. Even Google apps. But remember, by installing TWRP, you have already tripped knox, so you won't be getting any further updates from Samsung.
If you really want a stock ROM that you can backup with TWRP, it might be possible to format the data partition and then flash the stock opengapps for the version of stock ROM, probably ARM 32bit 8.1. But I don't know of anyone whose tried it. Of course, you need to backup any data you want to save and reinstall any Play Store or sideloaded apks you are using.

Plan is to try a couple of custom ROMs and if any issues go back to one of these: https://www.sammobile.com/samsung/galaxy-tab-a/firmware/SM-T580/ that shouldn't be a problem right?
Also I have wiped data which cleared everything and then when I tried to go wipe dalvik/system/data/cache in preparation for LineageOS, but it keeps failing because of /data, still encrypted after the initial format?
Why does it not work?

Did you choose the format Data option in the wipe screen? You should have typed yes to confirm.

 

[sd_dracula]

Got it sorted in the end, the problem was I had booted to the OS after wiping that instead of just installing the zip which solved it, thx

So glad I was directed to this forum thx @srgrusso. I flashed the official version of TWRP using the TWRP app from the app store and it work just like it was supposed to. Thank for suggesting I give it a try. I will be using it go forward, to verify, backup and update my TWRP from the official web site. Thanks again for all you do for the T580 device, you have breath new life and interest into this device for me. I love playing around with now.
