Like most or all devices when you boot it up it would show a unlock icon on the bottom of the screen if the lock is closed its not unlocked

very locked.

for those who like to tamper: there's a recovery firmware intended for the gtpab 8.4 for Ukraine available for download. Don't know if Kies works on this device yet.

But if you blow your device off the rails, this will get it booting again:

Oh, my, this is better than I expected - it recovered /system but didn't blow out my personalization. Freaking wonderful!

If your device "recovery bootloops," by which I mean:

you try a Chainfire root from the snapdragon note 8 on the tab pro 8.4
your device boots and tells you that you're bad, that Samsung knows your bad, and then displays something like

"RECOVERY IS NOT SEANDROID ENFORCING...
Set Warranty bit : recovery"

and reboots you, here's the fix:

take your a slim object and starting at the USB port, pry the backing loose one snap at a time, working left to right along the bottom and around the lower corners on each side.

Now, gently, start to pry down each side.

You'll feel central resistance. That's because there's adhesive holding the backplate to an internal frame that laps over the USB connector. Gently pry that up.

Once you're about halfway down each side, you can see the battery connector - six wires, two each black, blue, red. Keep going; there is another point of resistance at the camera housing. Gently finesse that last after you have all the other snaps off.

Free the battery from the mainboard by prying up the connector, or unscrew the 4 screws holding it in place and use the battery's weight to free it from the mainboard.

Let the device sit about 30 seconds.

Reconnect the battery.

Hold the home, volume down and power buttons simultaneously to bring the device into download mode and recover using Odin or your tool of choice.

Once you've recovered, button it back up.

Well, if it's not unlocked it's very free about what it accepts. I did blow the Knox flag but I was able to upload modified system.img, recovery.img and cache.img without any problems. And I now have a persistent root.

Good point - the OS is locked to void warranty, but if the flashable system images are that simple to load, that's great. The onboard recovery won't load them and I don't think Kies will, either

But I think it's reasonable to say that the upgrade mode on the samsung devices is analogous to an unlocked bootloader.

Can you share with us how you got root on your tab 8.4? I just bought one and I love it but without root it feels weird.... Thank you
