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.

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
So i updated to MK2 firmware this morning from OTA with my phone running Stock 4.3 MJA. I now realize there's a problem, as it WILL NOT LET ME TURN WI-FI ON. Each time I try, it force switches it off and brings up a KNOX notification saying that the attempt has been blocked. Can anyone tell me if there's a way to get back to the older firmware such as MF9 from MK2 right now? Also, I tried going back to MDC using Odin 3.07 and Odin 1.85, neither worked. Please help.

You can't.. Once your on MJA that's where you are stuck although I believe you can go from MK2 to MJA but that's about it. Otherwise there is no downgrading to any previous firmwares. Please read through the threads... All answers are here if you read...

Hmmmm...I'm now on MK2...just hoping there's some way to get back to MJA even. Also, another thing has caught my eye when the phone turned on. Music force closes and sound doesnt work one bit. Is there any way to factory restore the device at the moment with/ without using Odin? Like an MK2 factory reset file?

I tried the link, although their servers are down so I'm unable to download anything from that site. Is the file I have to download a large 1.53 GB file? Also, Sound doesnt work and Music force closes when i try to use it. Do you know of a way to hibernate or kill any knox related processes in the system so that it stops turning my Wifi off?

If he didn't take the ota he could of went back. Is that correct? Taking the ota locks the bootloader. If he updated with Odin and Philz recovery he could of keep the mf9 bootloader allowing him to down grade
Love the 90s good times
Waiting for the OP to post back if he was successful in downgrading MK2 to MJA by running the full MJA tar file. I know you can't go back farther than MJA but hoping we can at least downgrade back to MJA if we need to after a failed upgrade or bad ota.
I have downgraded mk2 to mja working fine no Knox flags tripped (still at 0×0). 100% stock everything.

I actually took the OTA from MJA to MK2. thought it would be a better update since it said that before i installed it. Instead, it causes more bugs on my phone, where i cant use Wifi and even play Music, let alone the fact that no sound plays at all on anything and i can't make a call...as the Phone app freezes when i try to make a call.

Please tell me what files you used. because at this point, I just wanna watch a simple Youtube video and call my friends! All of my data (contacts, pics, music) is already backed up on my computer. I don't have Root and i tripped the knox flag once so it says 0x1 which pissed me off

Hey thanks for being great helpers with helping me and my phone troubles...apparently my phone works again! Knox is not blocking my wifi and my sound and Music and Calls and everything is working! I'll post a new thread if any problems arise with this update. But to be honest...stick with MJA guys. Don't go through the same trouble i went through. Too much stress to handle when u can't make a single call or play your fave song or even connect to your beloved Wifi hotspot!
I can confirm that you can downgrade from mk2 to mja as I have done it. They process want difficult at all. Going that OP can get it going and it works out for them.

Ok one question...when u downgraded, where did u find the file? And did the file wipe your data?
http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy S4 (SPH-L720)/Stock ROMs/MJA
I used this. It did wipe everything from my phone. I just made sure to back up everything I wanted to save on my sd card using super backup. You can find that on the play store.

I had the same issue with WiFi not working and get the message. (For details: On a Stock rooted S4, Updated the Security policy and then flashed the MK2 modem).
I went to: http://forum.xda-developers.com/showthread.php?p=42954149 and followed the exact instructions to go back to MJA. It worked. I didn't lose anything. Only a ~26mb download.
Hope this helps.

I had the exact same problem as the OP with wifi and KNOX notifications upon toggling wifi. This had to do with a bad update which I believe was a result of rooting my phone. Something is weird with recovery after rooting the phone with cf autoroot as it no longer looks like the stock MJA recovery. So when I manually installed the MK2 update using what I believed was the stock recovery, I experienced serious issues such as what the OP described.
In any case, I used ODIN to flash the MJA tar which restored everything back to normal. Then I used the stock recovery to apply the update zip file and everything went without a problem. Then I flashed cf autoroot with ODIN and again, the recovery looks different from the stock MJA and MK2 recovery, but everything works fine. I did not do a data wipe during any step of the process and have seen no ill effects so far.
So the take home message is, if you rooted the phone ODIN stock MJA or MK2 if it becomes available before applying any future updates manually. Or ODIN a stock recovery file for your current ROM if one is available. KNOX has nothing to do with this. I disabled KNOX and still could not turn on wifi.
What if you have mf9 baseband? Can i down grade from mk2 to mf9 and if so how do I do this?

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 tried to update my sph l720 to unknownforce kitkat rom ....BUT
after i flashed the NAE modem and then flash the ROM after wipe...wipe...wipe....format...format ...format
My wifi and 3g data are OK....working.
but I can not make or receive any calls......Just i can receive SMS?
So what is the problem?
please help me
The Solution:
1)Flash mf9 stock odin file.
2)dial the code ##786# to return to sprint defaults.
3) update one by one...mf9>>mja>>mk2 then flash the NAE .
4) Flash the phone again to my local carrier using DFS.
Now all things are working great.
Have you updated profile and prl? What recovery did you flash with. What where you on prior to???

That means your firmware has already been updated to a version newer than MF9. Once you have gone to 4.3 (MJA or MK2) you can't go backwards to 4.2.2 (MF9). IF you have already upgraded to Kit Kat 4.4 (NAE) then you can't go backwards at all.

Thanks for your help cruise350. The knowledge of MF9, MJA, MK2, NAE helped me alot. Finally it's working now perfectly. I am running hellkat rom (NAE) now.

@dreamii, I'm confused? I am running the MK2 along side KK without issues. Did you have problems with the baseband? Did you upgrade to NAE baseband to get your calls to come in and is that what solved your problems?
Just trying to understand where it went wrong? LoL!

What I was running MK2 and hellkat 4.4 rom, I couldn't get any outgoing or incoming calls. And there is this sound issue also. The speakers, the headphone jack wasn't working. After I upgraded to NAE, it worked smoothly. In my case, combo of KK 4.4 and MK2 firmware was giving me trouble.
So this is what I did.
1. NAE stock 4.4 rom
2. NAE firmware flash with Odin 3.07
3. Wipe clean stock rom/cache
4. Install hellkat rom
Works like a charm now. :good::good::good:

Coud'nt you have just flashed the NAE modem then update PRL/Profile? Most times that should fix it.

I did try other KK Roms when I was at MK2 + some JB roms also. Same issue. I tried stock unrooted KK rom, TriForce JB rom, Omni Rom, Avatar KK rom. All had same issue.
I didn't thought of just flashing NAE and updating PRL/Profile... huh.. Should have done that so it save some times for me.
FYI, I just rooted a S4 with the MF9 BL and flashed LS KK with no issues, everything works.
I just flashed the NAE modem and after I wiped I restored my backup(liquidsmooth 4.4.2). Now I have no audio whatsoever. Please help!

Okay, go to your phone dialer, and dial ##rtn# (##786#), that will pull up the RTN screen, select view, then tell me what it says your SW version, OS version, Radio version and baseband versions are. Even though in about phone it says NAE, Ive found when I had sound issues due to an incorrect radio version "About Phone" doesnt always display accurate info, but ##RTN# always does. always, where did you get the NAE modem you flashed? when I flashed my first NAE rom, about phone said I was all NAE, but RTN showed that my radio and baseband were still MJA, which is why I had no sound, among other problems.
If in the RTN you see conflicting software or radio/issues ect, depending on whether you have already or don't care about tripping KNOX, just revert to a MJA or MK2 based custom rom, like a stock rooted 4.3 unodexed, then flash Unknownforce's NAE modem/firmware, then flash whatever Kit Kat rom you desire. I've had tons of sound/wifi issues arise by not flashing the NAE modem before the rom. Or just flash the stock .tar for NAE, root, rinse and repeat.
