I see that there is one firmware higher then BOJ1 on Sammobile...
T710XXU2BOL6. Its there for download so I figured I would point this out.

I personally have tried "Kies/SmartSwitch" and OTA and nothing will trigger this update.
Anyone have any insight into this? Also there is no source yet for it. (I have requested it)

Anyone running this yet?

Be careful with that update. It is a revision 2 and will likely be incompatible with revision 1 firmware and may prevent downgrade.

You are correct about downgrading but I've been running the Cellular South US version for awhile now and it's actually running fantastic.

For me it felt like a big improvement but I suppose that's more subjective...

If you're in the US, the Cellular South XAR is the one you want to flash...

You didn't have to wipe the data partition?

No. I just ODIN'd it and that was it.... I generally will factory reset anyway but doing this shouldn't wipe your data..... Just remember that the new bootloader is a one way trip....

So 5.1.1 is a huge improvement over 5.0.2? And if I FLASH official firmware from sammobile my tab won't loose data and knox won't be tripped? Rly want to figure out how to get 5.1.1 and root ☺

What do you mean by that?
According to Sammobile it goes BOJ1 and then BOL6...
Speaking of that.. any chance you could make a BOJ1 kernel that allows for root?
I would ask for a BOL6 but there is currently no source yet. (I have requested it) :D

It's bootloader 2.. Notice the b2 in the build number... Previous builds were a1, a2 or b1... You can't go backwards with bootloaders... You're going to be able to flash future releases that are b2 or higher

Oh right.. having a note 4 etc.. I knew that.
I thought it might have been something different.

The larger question is what is up with OL6...
It shows up when you use Kies to update the firmware but not when you use SmartSwitch or try to do it via the Tablet's settings menu.

T710XXU2BOJ1
Are the two firmwares I was referring to.
Thank you for explaining the build numbers. I didnt realize I could tell the bootloader from the build number.
So it appears they have the same bootloader.

The previous one that had a different bootloader was OH7.
This isnt an issue because I wanted to get away from OH7.

So if I'am running atm T710XXU2AOJ4 is this bootloader rev1 or 2 ? I see the 2 number in the PDA code. :/
Edit:
So ok atm there is 2 regions that got 5.1.1 canada and cellular south, that one with unknown looks with bootloader rev 1. Anyone from Europe can confirm that it's safe to flash the one with cellular south? Would like to get the 5.1.1 that try rooting it. ATM root should work with T710XXU2BOJ1? The custom permissive kernel is compatible with this firmware?

The bootloader is the 4th to the last letter in the build number.
So if you are "A" then once you flash ANY "B" build you will be bound to any build with a "B" in the build number etc.
However it seems you must be on 5.0.2...
Dive right in.. there is nothing wrong with 5.1.1 the only 5.1.1 version so far that seems to have problems is the first one OH7.
However you also need to flash the build for your region. For example Cellular south is XAR etc.
Use "smartswitch" you dont need to update the firmware but look at the prompts for the update. It will tell you what it suggest for an update before you give the OK. This is the easiest way to see what region code your tablet is.

Heh, I just flashed boj1 yesterday :D Now will have to wait for MM. My Tab is from Poland region and there is only 5.0.1 so there is no upgrade with smart switch. Anyway thx for the help ;)

What model code is yours?
XEO PDA T710XXU2AOJ4 CSC T710OXX2AOJ1. It was, now I flashed 5.1.1 boj1 south cellular with Odin and rooted it. One strange thing in 5.1.1. It looks like in 5.1.1 auto brightness is changed I can't use the slider in notification tray to increase or decrease the auto brightness. It just turn off the auto brightness. Rly annoying and looking how I could fix that :)

Not strictly true. It is possible to flash to an A build from B as long as they are both Revision 1(U1).
Revision 2(U2) usually prevents downgrade to U1 firmware.

The 3 characters after the B or A refer to the build date.
I.E.
O is 2015
L is December
6 is the build count.

So I can go and flash the T710XXU2AOJ4 firmware? Because it's U2? Not liking the 5.1.1 brightness slider. It turn off auto brightness :D And after flashing oj1 I don't have my language in menu. Can anyone check maybe Canadian version have Lithuania in it? Or maybe that unknown one?

P. S. Maybe someone know where I can find a full guide how to deknox 5.1.1 and what apps can be debloated. Would like to make ROM as light as possible. Thx in advance

It's in the build number. T710XX U2 AOJ4
T710XX U1 BOH7

Doh, so obvious lol...
Which is crazy cuz I see Sammy build numbers all the time..
I was on my phone posted before and had not looked at the build number since you informed me of the build.
