[Q] New GTP 8.4. Should I let it update itself?

I got a new Galaxy Tab Pro 8.4 (SM-T320) on Friday. $249 at Best Buy finally pushed me over the edge (yay!).
The current build that is on it is T320UEU1ANAI.
It has an OTA update available that it wants to install, but, of course, it doesn't tell me what the new build is. I have been clicking on Later, so far.
I expect that I will want to use TowelRoot to root this without tripping Knox, and I'll want to install at least a custom recovery and some Xposed modules. I may want to try a custom ROM in the future, and I understand that that will trip Knox no matter what. But, from what I read, as long as I use TowelRoot and just root and install a recovery, I won't trip Knox.
Is all that correct?
If I let this pending OTA go ahead and install, will I still be able to use TowelRoot and install a custom recovery without tripping Knox?
TIA!

Installing a custom recovery will trip knox.

Thanks, crpalmer. I read that TowelRoot doesn't trip it, but I was definitely still uncertain about installing a recovery and tripping Knox. Good to know.
So, anyway, if I take this OTA, will I still be able to root and install a custom recovery if I want? I've rooted and ROMed other devices in the past. But, I have a Verizon S4 and I already got burned with it by taking an OTA without researching thoroughly first. Now, my S4 is totally locked down and looks like it'll never be cracked. I definitely want to avoid that happening with this GTP.

Yes, let it update. Towelroot works with the update perfectly and than you can do twrp or just have root access and keep Knox intact if you need it for some reason.

I used towel root on a newer version as mine was already on the latest.
My future plans are much like yours. Stock rooted for a while, then custom recovery and roms.
Cheers,
Rich

Hi I just bought the Tab Pro from BestBuy. Is towelroot enough to root AND not to trip knox? Or do we have to flash the kernel from this thread?

That's all I needed on the latest US rom. No kernel update needed.

Towelroot worked on latest firmware.
However it did not work on the previous firmware. Tablet rebooted everytime.

[Q] Note 8.0 Custom Rom

Hi guys I am new to this tablet so any advice but be appreciated.
If i update to kitkat I am told the knox security feature would be installed too.
What if I leave my note 8.0 on 4.2 and root and use custom roms and then if I decide to unroot and flash kitkat, would knox be triggered due to historic custom roms?

Pretty sure flashing a custom recovery will trip knox. No way around it. http://forum.xda-developers.com/showthread.php?t=2800290

Ok thanks what if I just root and not flash a custom rom, would this trigger the knox?

It depends on the rooting method you use. The one I used to root 4.4.2 after I updated via Odin was Chainfire's CF-Auto-Root and that tripped KNOX because it installs an unsigned (by Samsung) custom recovery temporarily before re-flashing the stock version.
I've never used Kingo but they claim to be able to root the Note 3 without tripping the KNOX flag so their method using an Android vulnerability to gain temporary root might work for the Note 8.0 as well.
My suggestion would be to use these forums and Google to research all the current methods for rooting the Note 8.0 and make sure there are users who have done it successfully with the KitKat boot loader installed and not tripped the KNOX "warranty" indicator.
Based on the KNOX articles I've read it appears that flashing, or even booting, an insecure kernel can set the eFuse switch which is said to be "impossible" to reverse, so flashing custom kernels and ROM's is out even if you can get root with the stock ROM without tripping the indicator.
I can understand the requirement for KNOX in high security environments but automatically voiding the warranty is just encouraging users to brick their devices in ways that prevent the KNOX flag from being accessed. Perhaps Samsung's position is that once the eFuse flag is set even their service centers cannot reverse it so the device is not able to reconditioned and sold since a tripped KNOX flag also disables some security features in the stock ROM.
Edit: I just read your OP again and if you don't flash the 4.4.2 (KitKat) bootloader and root with CF-Auto-Root you should be fine, even flashing custom kernels and ROM's, and still go back to a completely stock configuration using Odin to install the stock 4.2.2 ROM and TriangleAway to reset the flash counter. AFAIK there is no check of any historical data when the KNOX enabled 4.4.2 bootloader is installed but I would make sure that TriangleAway has successfully reset the flash counter before upgrading just to be safe.

[Q] Does TWRP install trip KNOX

SM-T705, CF-Autoroot already. I was asked the above question. As I have rooted already I cant tell.
1 So if one installs TWRP recovery with Odin (not TWRP Manager apk) and just wants to backup his Tab, I would say there is no root necessary for doing this.
2 Will the Installation of TWRP with Odin trip Knox already ?
3 What is necessary for TWRP restore ... I guess root...

yes it will trip knox, anything custom other than an added binary (su.bin) will trip knox. Root isn't needed to backup/restore a ROM outside of Android, just a custom recovery.

If you have rooted with CF-Autoroot you tripped Knox already.

you con downgrade an older stock kernel w/out tripping knox ... but that's about all you can do. That said, I'd love to know if anyone has tried king, or towelroot. I'm too chicken. But towelroot DID work on our 8.4 tab pro (w/out tripping knox).

The thing is, is the tab pro exynos? I dont think towelroot works on exynos or some exynos devices

can't recall - but I thought it was the other way around - that towelroot (& kingo) won't work on snapdragon 's. I'll have to check to see what we got.

[Q] Rooting Questions

Hi All
I have a couple of quick questions regarding rooting my Galaxy tab s 10.5 T800 Wifi:
Can I install TWRP recovery without the tablet being rooted?
There are some builds listed in the Android Development section, where it states that its rooted, debloated and de-knocked. Does this mean that they can be flashed without rooting the tablet and tripping knox.
Thanks for your replies, still trying to get my head around this.
I posted this in Android development but think it was in the wrong post, if a mod reads this can you please delete it from there.

Custom recoveries like twrp trip knox no matter what. The custom roms will trip knox even if rooted becuase twrp is a custom recovery which trips knox.

Thanks mate

You can't root 4.4.4 without tripping Knox. TowelRoot used to be able to do it before 4.4.3, but the 4.4.4 "fixed" the exploit he was using.
If you flash a non-stock recovery it will trip the Knox flag. And, the only way of rooting with 4.4.4 is to install a non-stock recovery. CFAutoroot is your best bet, and then install TWRP, or CWM recovery.
