Stock Rooted MF9 No hotspot mod - Can I just OTA?

I have read through all 64 pages of this thread, and I'm just utterly lost. The only thing I've done to my phone since picking it up from the Sprint store is to root it using "CF-Auto-Root-jfltespr-jfltespr-sphl720.zip". I have NOT installed the MFP Odexed hotspot mod. My SUperSU app shows only 3 apps: CallMaster, DataSync, and Droid VNC server, however when I start SUperSU, I get the message: "Samsung KNOX has been detected, This might limit root capabilities and cause annoying popups. Try to disables KNOX?" I have always hit cancel here, and have never had any annoying popups, and everything works perfectly on the phone as-is. Last night my GF's unrooted Stock S3 got the OTA update downloaded, and I let it run, and she had not problems getting to 4.3 and it's pretty damn cool, and now it has me wanting to do the same.

I've read in other threads that the OTA will work if you are rooted as long as you don't have any mods installed. Is this true in my case? Can I just let the OTA run? It's downloaded and glued to my notifications bar, I'm just afraid to brick the phone, since I've been out of the scene since rooting my SII what seems like lifetimes ago. Any newb advice appreciated.

Software version: L720VPUAMF9

Hardware Version: L720.08

Any Consequences to letting the OTA run, or will it fail? I'd really rather get to 4.3 via official methods and then start looking at ROMS, but I'm just overwhelmed by all this new stuff like KNOX. Sorry to be a bother....
[Sprint Samsung Galaxy S 4 Android Development] trmitche2:
Please, anyone.... 10 seconds of advice regarding above post?

I honestly don't mind being called an idiot, but I just want to know what will happen if I try the OTA, & why my SuperSU is already detecting KNOX.... a little holiday generosity, anyone?
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
Good luck. I have been hoping for some help since December 2nd. I re-posted it, pm'ed it and emailed it to someone. No help. :confused: :crying: :rolleyes:
[Sprint Samsung Galaxy S 4 Android Development] Euclid's Brother:
I'm on MJA w/knox and I'm thinking of giving that vroot a try.. I'm new to this phone, but experienced with Acer A500 and E4GT.

Wouldn't this procedure ensure that no traces of malware are left?

1. download your favorite custom recovery and save on your sdcard on phone.

2. turn of all internet connection on the phone.

3. install vroot and run from a virtual machine. Throw away the virtual machine when done.

4. boot phone, which should now be rooted. (shouldn't be able to access internet due to step 2).

5. install the custom recovery. (dd from adb? rom manager? other?) <-- will this mark knox?

6. boot recovery and install pre-rooted MJA/MK2 or custom ROM.

7. wipe data/factory reset.

8. reboot phone and install SuperSU from play store.

Wouldn't that leave you with a rooted ROM w/o malware + custom recovery?
[Sprint Samsung Galaxy S 4 Android Development] trmitche2:
Thanks for the reply Shardog. What kinds of things are happening with your phone after trying to OTA to 4.3 while stock rooted on Mf9? Did the update just fail? Or are you partially/totally out of commission? Were you in the exact same situation as me,(stock MF9 rooted w/NO flashed mods, and KNOX already being detected despite that)?

Why do you think no one is interested helping u out, especially since we've read every page? This would seem to be the right thread. Maybe we should try the pinned "newb questions welcomed" thread in this same sub-forum? Please let me know your thoughts... that is unless anyone with -uber-geek-god status could be bothered to toss us a mercy post or 2.
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
I was stock MF9, rooted with the hotspot mod. Other than that stock. I hit the OTA by accident and it failed. I then tried the QBKing method of updating from the sd card. That fails too. The rest is in my original post. Everything works I just keep getting the update notification. I would like to be on the latest version.

I don't know why no one answers. This forum is a great wealth of information.
[Sprint Samsung Galaxy S 4 Android Development] screaming01l:
Is it worth updating? Im still on mf9 rooted and wifi mod. I just keep ignoring the system update.
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
How do you know which bootloader you are on?

thanks :confused:
[Sprint Samsung Galaxy S 4 Android Development] Euclid's Brother:
in Settings -> Security -> Device Administrators, mine shows KNOX at the top.

or (most reliable way) boot into download mode (vol down + power). There will be several lines of tiny text. one line will reference the KNOX counter if your on the KNOX bootloader. If it doesn't say KNOX there, then your on the old bootloader.
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
Thanks a lot. :good: Mine doesn't say anything about knox on that screen. So am I good to go with the stuff in the OP? :confused:
[Sprint Samsung Galaxy S 4 Android Development] trmitche2:
So how about me then?

Being that I am on stock rooted MF9 with No flashed mods (but with knox detected when I start SupSU? even tho all my components are mf9)

Could it be that the auto-rooter that I used (see previous page 64 for the auto-root file i referenced in my OP to this thread) has also installed a modded MF9 that seems to have added KNOX before people were so well aware of it) I understand that I will not be able ro revert or use future official OTA build) if a I usee OTA to get to 4.3, but I just want to know lwhere I stand, before II follow the steps5 in the very complicated (but extremely helpful) YuoTube video
[Sprint Samsung Galaxy S 4 Android Development] Euclid's Brother:
I'm not really sure, as I'm new to this phone. But I'm thinking if the download screen doesn't mention KNOX in those tiny lines at the top, then you definitely don't have the KNOX bootloader.
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
Well I seem to have run into a bit of a snag, before I do ANYTHING I thought I'd ask. I have installed philz via odin and then realized that I had not yet downloaded the ROM so I tried to "restart system" (this was after a clean wipe) it was stuck on the Samsung GALAXY S4 boot screen for about 5 minutes so I tried power on-volume up button to boot into recovery and now its stuck on the battery charge indicator (like when it's off and charging). Should I pull the battery to restart? What should I do?

Well I pulled battery and was able to boot into the new recovery then restored from there.
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
Just keep holding down the power button.. Or get into DL mode reboot.. That's what I do anyways.. If it's plugged in and it's charged unplug it and try to hold power.. If it's dead leave it plugged in for a while and try again in 10mins

Once you do get to recovery or get your phone to at least boot.. USB to pc.. DL a rom and copy it to your SD, then flash rom
[Sprint Samsung Galaxy S 4 Android Development] ardy:
Hi All,

I've read through this thread and have questions that I don't see clear answers for so I'll ask them.

I followed the procedure on the OP and it all worked great. I've be running this setup for a while. Now I see there is a new modem (MK2) update.

Can I just update the modem to MK2 with Odin and leave the ROM alone?

If I do, will I lose the hotspot mod? I'm not sure if the MJA hotspot mod is specific to the MJA modem.

Bottom line is I want to end up with a stock rooted rom with the hotspot mod and the latest modem.

My current setup is:

Android version - 4.3

Software and Baseband - L720VPUEMJA

Kernel - KT (from OP)

Thanks for ant help and thanks for all the work you guys do.
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
I went ahead and did all that is in the first original post. It worked . took a couple tries but I now have 4.3 MJA with the 4.2.2 boot loader and no knox.

Now my question is how do I go about MK2 update? I am getting the update notification. Do I have to flash the MK2 modem in odin or is there more to it?

Thanks
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:

I have not tried the hotspot mod so best to read through the thread, good luck.. For me mk2 was worth it.. I get better 4g coverage..
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
Thanks, Yeah the restore did not work, just keeps booting into download, I can get it into recovery so as soon as the ROM DLs I will install it and hope for the best.
[Sprint Samsung Galaxy S 4 Android Development] ParkerParker:
If you have recovery.. Your good to go :thumbup:
[Sprint Samsung Galaxy S 4 Android Development] ardy:
Thanks for the fast response Parker.

I did the MK2 update with no problem. I noticed when I have a 4G connection, I barely get one bar and in 3G mode I get almost full bars (both in the same spot) I like the 4G connection, but pay for it on signal strength. I may just set the mobile network setting to CDMA only for now.

Tried the MK2 hotspot mod and gets stuck at yellow logo screen. I reloaded the MJA hotspot mod to get the phone to boot. Just for the hell of it, I turned on the hotspot (MJA loaded) and the hotspot still worked. Maybe you don't need the MK2 hotspot mod.

Thanks again.
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
OK back up and running, I did not wait the 5 minutes so I'll see if there are any bugs. However I have a notice in the dropdown notifications "System update downloaded, touch to install" what should I do about that?
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
Anyone?
[Sprint Samsung Galaxy S 4 Android Development] rlmiller:
If you have custom ROM the install should fell it should not go through ...

you will need a edited or update build prop for your ROM... check your ROM maker thread and see if he has a new updated version ...sometimes it's a simple flashable zip file yeah and the recovery that fixes it
[Sprint Samsung Galaxy S 4 Android Development] neno2323:
I'll bite I'm new to the gs4 comin over from LG Optimus g. I followed the O.P and had success .. But I was getting the mk2 update and I knew that was not rite. So I searched the thread and found out if I hold down on the notification that little window popped up and then unchecked it... so yeah everything good...
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
It's the stock ROM from this thread so it's current and should not be getting the update.
[Sprint Samsung Galaxy S 4 Android Development] rlmiller:
Then try what [MENTION=3402551]neno2323[/MENTION] said
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
That did it.
[Sprint Samsung Galaxy S 4 Android Development] trmitche2:
Ok, since another gentleman just got meaningful feedback with a simple bump, I guess I'll try the same thing - short & sweet (relative to my last post at least, quoted above):

"Anyone?"

*Please*, can someone just at least take an educated guess as to why KNOX is being detected by SuperSU, when I'm definitely still on stock rooted MF9 with no mods? It really worries me! How can KNOX possibly be on my phone? Most importantly I guess, should I allow SuperSU to "attempt to remove KNOX" before I follow the OP's process to try to achieve what this thread is all about? This makes no sense, and is worth being concerned about, right? (stock rooted MF9 w/SuperSU detecting KNOX) ?????
[Sprint Samsung Galaxy S 4 Android Development] Shardog:
Mine did the same thing. I was on MF9 rooted and after getting the OTA update and it failed I got the SuperSU knox detection. I said yes remove it. I then went ahead and did the process from the original post and it worked fine for me.
[Sprint Samsung Galaxy S 4 Android Development] mocoyombiflash:
cf autoroot works temporeraly until the supersu app updates by itself then it will loose the binaries my solution was cuz i flash phones for a leaving i need it to add apn back as a system app i can't unless i have root and i'm mja 4.3 with newest bootloader so my trick was to get root access for root explorer etc was to flash cf autoroot when it rebooted i automatically put the phone in airplane mode this doesn't allows the super su to update and you can optain root if you force stop the app and don't let it get a newer updates if you do let it update it will ask for su binaries and you will loos su permission.
[Sprint Samsung Galaxy S 4 Android Development] EVObastard:
Did you ever figure this out, I am having the same problem. I have to sign in to WiFi after every re-boot, it will not store network password.
[Sprint Samsung Galaxy S 4 Android Development] trmitche2:
Hey, thanks for that info Shardog, but I believe the significant difference (between your situation and mine) is the fact that I have never even attempted the update, so it has never tried and failed as yours had, which would explain why your phone's SuperSU detected KNOX. However, since I am 100% certain that I have never even been to the initial page that is seen after touching "System update downloaded - Touch here to install" in the notifcation bar, my curiosity persists as to why my SuperSU is detecting KNOX at all. Could it be detected just by virtue of the system update having been *downloaded*, even though its installation has never been attempted / failed? I'm going to follow the OP process regardless. So thanks in advance to anyone who can explain it, for no other reason than my own curiousity and confusion.

P.S.: Things change *so* fast around here... I realize that this entire thread may very well be entirely obsolete by now for all I know. Between the holidays and work-related travel, I admit that I haven't exactly been keeping up with recent developments in the Sprint S4 scene and the implications of KNOX and any possible new hacks related to it. I trust that *some kind soul* will let me know & link me in the right direction if that is the case. Sorry, but I figure it's better to be honest in this situation than to pretend that I'm all caught up when I'm not....

Am I just dense, or is there a problem? Namely, the Rom thread you link to in the OP says that that the only version of Philz supported is 6.08.9. That comes as a .zip, not a .tar, and thus cannot be flashed by Odin. So how am I meant to run that version?

I followed the steps but device a'int doing too good :(

I was on MF9 stock rooted (with TWRP recovery installed when I flashed the NAE modem via odin 3.0.7, not sure if that makes a difference).

All the steps seemed to go okay. Verified versions are good. However, the device is super sluggish at times, especially the dialler. Sometimes I have trouble waking it.

I have not set up any of the google stuff or the the hotspot mod or sd card mod yet.

Help! Any ideas??

Update: I went ahead and connected the phone to google which it did fine through the cell network. The phone is still basically unusable though and also I have realized that I can't toggle the WiFi on.

Update 2: Everything seems okay now. I went back and flashed the MK2 modem, then reinstalled the MK2 ROM, then the NAE modem, booted into MK2 to see that it was okay, then installed the NAE rom. So far so good :fingers-crossed:
[Sprint Samsung Galaxy S 4 Android Development] SixSixAtl:
Feeling happy!

Hey Mudavo I was encouraged by all the positive feedback in this thread so this morning I decided I would give your procedure a go and upgrade to NAE. I realized that WiFiHotspot was the only mod I needed to flash and that all of the other mods I need to configure my phone the way I like are apk based, so there was no reason for me to wait around for a deodexed version of NAE! Prior to upgrading, I had been running on Stock(ish) V06 and two of its previous versions before that and have stuck with the MF9 bootloader.

Everything is working great! I flashed KT's 4.4.2 TW kernel and continue to run the "What Lies Beneath" profile which so far seems to be giving me the same prolonged battery life that it did when I was on MK2. For call recording, I installed skvalex's CallRecorder version 1.5.3 beta13 apk available at

http://xdaforums.com/showthread.php?t=1441643

which is performing even better than the modded secphone.apk I was running on 4.3 *plus* it records when I'm using my bluetooth earpiece!

Edit: this morning I flashed KT's latest kernal (KK4.4-03/12) which according to his thread should eliminate the problem with the touchscreen becoming unresponsive (which I only experienced once or twice a day and only with the lockscreen) as well as the new TWRP 2.7.0.1. So far so good!

soft bricked - very sad

I am :( soft bricked.:o

Odin failed on 1st step NAE Modem/Firmware. It started to write and progress bar stopped under the "n" in "Do not turn off target".

I verified the BL is MF9 before I started and my current software version, baseband, & build number are all MF9. I started with downloading all the files in OP. I have both NANDROID & TB backups before I started.

When NAE modem/Firmware failed, I attempted to install the Philz Recovery via Odin. Same thing.. It started to write and progress bar stopped under the "n" in "Do not turn off target".

So, I am stuck. It powers up to the "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.". I can still get to download mode but Odin failed.

I did the MF9 update using Odin back in August 2013 and made sure not to get the Knox BL. Not sure why but by skipping the updates between MF9 & NAE did I miss something? Do I need a PIT file?

Trying to update the Samsung USB drivers to Samsung_USB-Driver_for_Mobile_Phones-1.5.33.0 and try Odin one more time.

Desperately seeking advice.
