Looking to unroot and want to know when did they introduce the knox bootloader. Basically I want to downgrade and let my phone upgrade back to nae with ota's. I'm currently nae modem sac's 4.4 rom..
MJA I think. Once you take OTAs to NAE you will have Knox.

Why take the ota when you can just install the full nae tar and be updated in one quick and easy step.

I just got a S4, and am currently running rooted stock, and already have a nandroid created. I want to try out some different ROMS...I've noticed that there are some issues with MF9 and MJA.
1. Does anyone know if TriangleAway works with MF9 and MJA?
2. How hard would it be to go back to my rooted stock if something goes wrong
3. Is it any harder to unroot after upgrading?
Triangle away does work with MF9, make sure you are on the stock recovery to use it. MF9 is the most stable of the builds. MJA is great for me but some have had problems. If you do the upgrade to MJA and the bootloader is upgraded to the MJA bootloader than you will not be able to downgrade your bootloader. People have successfully installed 4.2.2 roms and AOSP roms once upgraded to MJA which is 4.3 but you have to make sure you know what you are doing before you screw around with it. Since there is not a full tar file for MJA if you soft brick your phone there isn't an easy odin fix to get back up. It is a much more complicated procedure so be careful.

Thanks cruise...so I take it any 4.3 ROMS that are out are using the MJA (Knox) bootloader?
I am trying to decide whether or not it is worth the effort to update to MJA without updating the bootloader per http://forum.xda-developers.com/showthread.php?t=2277480. I am now running 4.2.2 pretty much stock with root. I would like to run the same way on MJA, but don't want to have the wifi problem and would like the option of running stock kernel. I have not been able to find what is causing the wifi problem. Are people taking the OTA experiencing the wifi problem? If I were to install the update as described in the link above without the KT kernel, what is the difference between that and the OTA, other than the bootloader? Why would it experience the wifi problem and not the OTA?
From what I have read you should be fine. I am trying to make the same decision. I'm basically stock mf9 rooted and tweaked.
My understanding is that we could Odin the mja with root and be like we are currently with all the new goodness. The disadvantage, if it is one, is that we could not go back to a mf9 rom due to now having the mja bootloader. I am trying to wait for one of these amazing devs to get a tar or zip together that would be a one flash setup allowing us have all of the new stuff minus the mja bootloader. I don't think I would ever go backwards but I don't want to destroy that option. I probably won't be able to wait much longer and wind up jumping through all the hoops to get the mja modem, 4.3, and keep the mf9 bootloader.
I am in no way a developer and please someone correct me if I am mistaken. I hope this helps you in some way.

I just did what you're thinking about doing and my experience has been great. I have the full MJA with out the bootloader. The phone runs stable and fast. No Wifi issues, LTE works, and clear phone calls.
It was more time-consuming than flashing a tar but I'm liking MJA a lot right now.

Are you running the stock kernel or KT kernel?

The KT kernel with the wifi fix. I didn't mess with the KTweaker settings.
I'm currently running MDC rooted stock with stock kernal. if i update using the thread posted by the OP. Will i be using MJA or MF9 bootloader...i've read throught the instructions and don't see anything about flashing the MF9 bootloader, or would that be the step which removes Knox

Before I started on the guide, I was on stock, rooted MF9. After the guide, I was MJA everything except the bootloader, which is MF9. As a result, Knox isn't triggered.
Since you're currently on MDC, perhaps you should start by flashing the OEM MF9 tar first through PC Odin.

damn...another slow 1GB+ download
is there one floating around?
i looked but didnt see one
Most Roms are MJA or MK2 now as devs always stay on top of the latest updates. Download stock rooted MF9 and debloat it yourself. I can't remember which ROM might still be on MF9,

i have done the domestic lock so i thought it was good to stay on mf9 with mdc modem. thought about flashing modem back to mf9 as the modem will still stay unlocked but if i goto mja or mk2 i think i loose the unlock carrier mod and plus how do you all deal with knox?
figured most people would still want to stay on a firmware you could downgrade when you want and flash what you want without to much trouble
you think i should stay on mf9 considering my needs or is mja and mk2 ok to upgrade to now?
I am still on 4.2.2, stock rooted. I don't believe I have a custom bootloader. I have the nag message to upgrade to OTA 4.3.
What are my options at this point?
I'd like to keep root or reroot, if possible. I'd also like to make sure I can recover all my app settings easily.
Thanks!

If you want NAE 4.4.2 stock unrooted then you can just grab NAE tar and Odin it. If you don't care about Knox then you can root it and restore apps with data from titanium backup.

What if I *do* care about Knox?
Are there any options?
Ideally, I'd like to be rooted on the latest release without the Knox problem.
If you do care about tripping Knox for warranty reasons. Then there is no way to root Knox without tripping it on 4.4.2. Although you could keep your MF9 BOOTLOADER and flash the stock rooted NAE ROM by unknown force. Plus Odin NAE modem.

My warranty is with Square Trade. So, I guess the Knox issue would only come up if I have a software issue that requires me taking it to Sprint, right?
Can you elaborate on "Although you could keep your MF9 BOOTLOADER and flash the stock rooted NAE ROM by unknown force. Plus Odin NAE modem. ", please?
Thanks again.
Knox from what I know would only come up if you needed to ship your phone to Samsung for warranty reasons during the first year of purchase.
Use this method and you won't have Knox bootlaoder at all but will be on the latest KitKat update.

Thanks. I'll head over there.
I'm currently running the leaked kitkat NC2 build with safestrap recovery installed and I need to unroot and return to stock tonight. I'm meeting someone tomorrow at a Verizon store to trade devices. Needless to say I must be stock. I'm aware root will be lost yes. What I wasn't sure of, is, is there a way I can unroot and return to stock but with the latest ota kitkat firmware? Is this available yet? If so can someone please point me in the proper direction for how I do this. Thanks.

Well, all you need to do is Uninstall su and flash the official mje tar in Odin and update to kit kat by accepting update . Otherwise , there is an official tar for nc4 on the Samsung website and flash in Odin
