Need some assistance and info.

Phone info via the settings says the following:

Model #: SPH-L720T

Baseband: L720TVPUBNG5

Kernel is dated July 31st

Build #: KOT49H.L720TVPUBNG5

That being said, I would like to root this phone, but I don't want to trip Knox at all.

I know that a custom recovery will defiantly trip Knox, but will flashing via Odin trip Knox. I have rooted before so I'm not afraid of the root process I just do not want to trip Knox is all. All I want is just your basic root nothing more as I won't be flashing any ROMs.

Can I use Odin to flash a tar file and obtain root that way without tripping the Knox counter? If so can someone supply a link to the tar file please.

Most of what I've read is rooting as well as a custom recovery, and I am guessing the cm-autoroot way installs a custom recovery, therefore trips Knox which I do not want to do.

I tried towelroot + SuperSU and it didn't work. Sprint has sent out an update that plugs the exploit that towelroot uses, so it no longer works. The dev now works for goggle so a fix or update I don't think will happen, so towelroot is out of the picture.

My IT Dept told me that custom roms are not safe and may have the ability to track passwords and financial info. Is there any discussion of this on xda? Are there people in the community reviewing code to see if there are any crooked devs?

Do you really think Google is not tracking passwords or financial records?

They record and save everything

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] skandranon314:
In theory custom roms could do that. In my 4 years of flashing custom roms I have never, ever, heard one single instance of a dishonest dev trying to do this. You do have to be more careful with a rooted phone than a stock one. Your mileage may vary.

Galaxy S4 won't boot past splash screen

While browsing the Internet the other day on my, my S4 turned itself off. Since then I haven't been able to get working. It will power on and show the black and white "Galaxy S4" splash screen for a fraction of a second and then it will shut off. It is also only possible to get it to boot that far by removing and replacing the battery. Unless you replace the battery the device will not power on. Period. No button combination will work. Plugging the phone in makes no difference. Leaving the battery out for an extended period of time makes no difference. I have never tried to alter my device from it's original state in any way other than standard OS updates.

So:

Will only turn power on once per battery replacement

Turns on immediately after replacement of battery, no time for button pressing

Shuts off at Galaxy S4 splash screen

Button combinations seem to have no effect

Charger seems to have no effect

Never tried any funny business or alteration of the device

Any ideas???

I think would also be fair to say that a rooted phone gives you the ability to BLOCK a lot of invasive stuff that you wouldn't otherwise be able to (not saying you are denying this, skandranon314)....

NG2 Rooted One Click or TAR

I am new to the S4 (L720) and previously had an S2 (E4GT). I've been looking for a rooted one-click or tar of the NG2 because thats what my phone came stock with. I've read about getting your phone knoxed by installing a recovery and saw that if I use CF autoroot, it would get it knoxed too. Please help.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
You could do like I did and use an app called towelroot. It will root without tripping the Knox flag.

The way I had to do it was download supersu from the market, Google a search for towelroot and download it, install both apps, run towel root and make it rain, run supersu to update the binaries. Once your done you should be rooted.

If I'm not mistaken you won't be able to update binaries without root but I could be wrong.

Also you may get a message about disabling knox, at that screen hit cancel or no.

To check to make doubly sure you have root get an app called root checker from the market.

If you don't want to trip Knox this is the way to gain root access. Do NOT install a custom recovery, if you do it WILL trip the Knox trigger.

If you don't care about tripping Knox then I would recommend rooting another way such as cm auto root with a custom recovery.

Tripping Knox does nothing physically to the phone, it just trips a counter that cannot be reset back and if anyone knows to check it will know that you have rooted or at least tried to. Other than they The phone works like normal.

Just a short update, I finally got my phone flashed firmware back to nc6 and rooted and ota disabled.

I'm now enjoying root without the stupid ng5 update annoyances of flaky data cutting in and out on me and wonky wifi issues.

I found out my brother in law has the att s4 and got no update at all, so this push was done by sprint.

Pretty sad when an end user has to fix an issue themselves because the carrier won't admit it had issues, even though forums have multiple people with the same issue and same results because of this update, yet is still magically is not an issue (scratches head).

Anyways I'm finally done and up and running. Thanks for all the help.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dvs323:
Thanks for the response easyrider. I saw qbkings thread tried using Towelroot first but it tells me my phone is not suppport or doesn't recognize my phone. As for tripping knox, I read about voided warranties when trying to get a phone repaired due to drops so I'd like to avoid it if possible.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Yeah, that's correct about the warrenty, its is void once you trip Knox.

As for towelroot it doesn't work on ng5 at all, so if your on ng5 you'll have to flash back to nc6 to use towelroot to get root with the method/way I described above.

Let me know if you are going to do it that way and I'll try and post a more specified how-to.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dvs323:
I'm actually on NG2 and have read others having problems with towelroot on NG2. Not sure if theres a difference from receiving the OTA NG2 and flashing a stock NG2 tar from another thread but towelroot isn't working for me.

I was also under the impression that I flash an older tar such as NC6 I can trip knox. I read you can flash the same version or new and not trip knox. Is that not correct?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
As long as it's KitKat it should be fine. Its when you go from KitKat 4.4.x to like 4.3 or below, that when it bricks the phone.

I flashed firmware from ng5 back to nc6 just fine, it doesn't trip Knox at all.

I think you can flash firmware as long as it's the same version, ie: KitKat with KitKat, ice cream with ice cream etc.

Anything that adjusts or tampers with the boot loader or boot partiton, such as a custom recovery, that's what trips the Knox flag.

Towelroot works because it uses another method of rooting within android itself and is considered an exploit or a hole, this is why patches or updates are being put out to plug said hole or exploit.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dvs323:
Thanks for the clarification. So I'll have to flash to NC6 in order to get root using towelroot but will I be able to flash the NG2 model tar I seen on another thread so I'll have the latest modem?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Well it depends on what carrier you on as to what firmware you'll have to use. I think your is att branded, so it may well be different for you. Mine is a sprint carrier.

I'm not really sure about the updating also, because nc6 and ng5 are both sprint, ng5 being the latest. It's not the same for all s4's
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dvs323:
Sprint is my carrier too and read that the previous firmware for my phone was NAE. Maybe its because you're on a L720T and I'm on a L720.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Ah ok, yeah I'm not sure then.

I don't want to mislead you, so may be better asking someone with that phone. I don't know if flashing my phones firmware on yours would mess things up or not. Good thing I noticed the different firmware number heh could have been messy.

Sorry , wish I could be more help.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
No, you can use towelroot and not trip Knox. I'm rooted, but Knox is in tact.

Now, if you want to use a custom ROM or custom recovery, then yes you'll have to root and trip Knox

Tripping Knox

Can anyone else confirm that if I flash from NG2 to NAE, it wont trip knox? I'd like to root my phone and there doesn't seem to be a way without tripping know for NG2.

You could go here and read to see if this is what you are looking for. It is NG2 stockish Rom rooted, knox free. Read all the thread to see if it is what you want. It may not be what you are looking for.

Thanks for the recommendation. I came across that thread and read through it before. My understanding is that I would need to flash the rooted stock ROM in a custom recovery though and flashing a custom recovery would trip knox. Is that not correct?

App data wont go away

Hey all, I have an app that I regularly uninstall/reinstall to get a fresh install of the game. For some reason on android it refuses to let go of the data when I uninstall it. I uninstall and reinstall and I'm taken back into the same thing as tho I had never uninstalled. I've tried titanium backup doing a data wipe of the app and uninstalling it, I've tried System Safe App remover and I've tried SD maid and none of them are able to get rid of this data and give me a fresh install. Google searches return no answers. Any insight?

REPOST! anyone?

Need Help getting back to stock ROM

last December I connected my phone to my PC to back it up using Samsung KIES, but KIES notified me that there was an update for my STOCK firmware (I thought it was getting the new Android 4.4) so I clicked on it and let it update.after update was installed, & phone was restarted

everything was working fine but the Wi-Fi wasn't working AT ALL! it wouldn't even turn on/off!

and since Sprint service was really bad in my area so I had no choice but to research online on how to fix this problem.

I believe I followed QBKING77 blog/youtube videos and flashed my stock rom and installed Cyanogen Mod (using CM installer) and been using it since then.

I really want to get back to stock rom and use TouchWiz stuff so how can I do that without ruining my phone?

is it possible to keep Cyanogemod AND install Stock ROM?

I'd really appreciate it if someone can help me

Phone Model: SPH-L720

Android Version: 4.3.1

Baseband Version: L720VPUAMDL
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] churchey360:
Your wifi probably wouldn't turn on because your baseband didn't match your software version because when you take an update it doesn't always flash the new baseband correctly (Happened to me).

To get back to touchwiz is pretty simple you just need to flash the .tar file with odin on a pc ill provide you a link for the .tar file for the latest NG2 update.

You need to make a sammobile account to download the file.

Also you cant use 2 ROMs at one time lol. The .tar file will completely unroot your phone and take you back to stock touchwiz but it will also completely update you to NG2 4.4.2 (Latest update)

The problem I'm having is saving the file to my SD card in case I ever need to use it again.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
It's possible that the size of the file is greater than the maximum file size permitted by the file system type of your SD card.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] easyrider77:
Yeah that's possible. It's a 1.5gb size file.

I also tried copying it to the internal storage and got the same problem. It's almost as if the file gets corrupted when using it, not sure.... I just know I had the same result on both the SD card and internal storage.

Hi and thanks in advance for any help I can get. I've read tons of sprint s4 pages but I still don't know what to do.

What I have:

My aunt brought me (I live in argentina) a S4 from Sprint she wont be using any more because she got the s5.

Of course is locked so I get the invalid sim when I try my Claro sim.

The baseband is the NG2.

Android is 4.4.2

What I want to do:

Use all the phone functions and Claro 3g network if possible keep the latest android .

I don't know if it's possible just to flash a stock samsung ROM and that will unlock it or follow the instructions of the OP to unlock it with the baseband that I have because right now all I can do is us it as a tablet.

I read a lot of the International sim unlock thread but I couldn't find a tutorial for the NG2 baseband and a lot of people is looking for the same solution.

Each new ROM I flash will attempt to "activate mobile service" upon first boot. Is this because of Sprint's automatic activation with their devices?
