I've been using it heavy yesterday and today since using your sql method and it's been perfect so far. I'd like to give it a few days maybe a week before I'm convinced all the way. However, it's really looking good, and I think we have a stable naitve mod solution with your sql version of the telephony.db mod (even on NC6 :) )

I'm rooted and custom recovery

I have a Galaxy S4 Sprint Sph-720t vpubng5 on 4.4.2 kit-kat and am rooted with TWRP custom recovery. The important things here are the 720T and NG5.

The first thing I did was to go to Samsungs website and download the stock rom tar from them in case you do mess up your phone(It installs in Odin)

The one that worked flawlessly for me was CF-Auto-Root-jflterefreshspr-jflterefreshspr-sphl720t.zip(Odin). Notice it ACTUALLY says 720t. This will root, install TWRP custom recovery, install SuperSU, and when in Odin you uncheck EVERYTHING, Do not let it reboot...you pull the battery and then boot into TWRP recovery and install UPDATE-SuperSU-v1.30.zip, then you just reboot system, open SuperSU and it automatically detects Knox and asks if you want to disable it.

Instructions and files are in this link here:

http://xdaforums.com/showthread.php?t=2621862 :victory: :victory:

Scroll down to where it says TWRP SUPERSU METHOD under ROOTING. They also have the links to the stock firmwares on Samsungs website for the NC6, NAF, MK5 and NG5. You have to register with them to download them.

I tried one that said it installs CWM(Clockwork), it went through the process, said PASSED and when I rebooted into recovery it was still the stock recovery.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Really?

1) All the samsung stock firmware links are in the OP of this thread

2) The TWRP supersu root method is in the OP of this thread

3) Your URL returns you to this same (my) thread

4) Both the 720 and 720T cf-root files are confirmed to work on the 720T, and both are listed in the OP of this thread.

5) Most of these things have been listed in the OP of this thread for months.

I'm not one to tell a person to read all of the time instead of just helping them, but have you even read the OP of this thread before posting on it?

If you are excited about all of this, check out the OP of this thread. You will probably find some more exciting stuff.

My phone feels new with the new toggles and stock hotspot enabled. Just ran hotspot about 4 hrs straight, flawless.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Yea, it has been rock solid for me too. Used it for a few more hours today. In a couple of more days, I'm gonna have to rewrite the native toggle section of the op and give cooljb some props.

td030981 can you please remind me again whether you are NG5 or NC6?

Also and for my own learning, could you please tell me when do you like to use the mobile data toggle? I'm trying to figure out when I should be using it if at all.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
Nc6. I use the data toggle when my signal drops to 3g and I want LTE back. It's quick on reconnecting too. I was using a app before.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. I thought when the phone auto drops to 3g it is because there is no LTE in the area, so why would turning off the toggle give you back LTE? Also, I thought the toggle turned off all data (LTE, 4G, 3G and 2G)

Clearly, I'm missing the point orI am off base and don't understand mobile data toggle :p

Please help me understand.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
Also, if you go into an area with no signal at all turn it off, it will help save on battery life, not using battery to find signals.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Agreed and thanks. That's the only reason I thought of in the past to use the mobile data toggle.

However, I want to make sure I'm not missing some other benefit because the mobile data toggle seemed so important to everyone else.

Updated/completely re-wrote native hotspot section of op and added credit to cooljb.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Cooljb:
Thanks! :good:

I meant to post over the weekend that the latest version of Galaxy Tools does now work on NG5. It even auto-reboots after you push the enable native hotspot button. As I mentioned before, I had some correspondence with idone when I couldn't get an earlier version of Galaxy Tools to properly enable hotspot. I had sent him my working, manually edited telephony.db file at his request, so maybe he used that to update his app. However it happened, I can confirm that the latest version of Galaxy Tools does correctly modify the telephony.db file and does enable native hotspot. And the app is now in the play store. You may want to update the Galaxy Tools section of your OP as well.

Thanks again for this thread.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
Turning data off then back on was what I meant. I was the data toggle to cycle the radio. If you are on lte and for whatever reason your signal drops to 3g, for me, toggling the radio off then back on connects back to lte. Sprint had that lte discovery app on play store and that's what I was using but the toggle is much faster.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. I was going to ask you if you had informed idone to help him fix Galaxy tools for us. Now I know :)

I appreciate all you hard work.

Thank you.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. I think I understand. I have seen times when the auto detection/switchover lags and takes an excessive amount of time to switch back when LTE signal is available again.

Toggling this could speed things up in those instances.

Native hotspot Galaxy tools section of OP updated
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
After Galaxy tools makes a backup of telephony.db, I wander if it uses a telephony.db file swap method or whether it actually adds the dun parameters to the current telephony.db file.

Adding the dun parameters to the current file would be the best option but would require more coding. This option would be best because you could do a profile update first to ensure you have all the latest settings for other aspects of the phone and not lose those latest settings/snapshot when you activate tether with Galaxy tools.

It would also ensure that the telephony.db file that the tool uses is the most compatible file for the users particular Galaxy phone model and revision (i.e. GS4 720T NC6 vs MK5 vs NG5 etc) in case there are any differences.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Got a reply from idone. He said Galaxy tools no longer uses the file swap method. It updates the current file after making a backup. It sounds to me like galaxy tools should be rock solid now for native tether on 720t for all those who are not comfortable with sqlite.

He also said that a factory reset and a profile update are the only things that will reset the telephony.db file. In which case, you have to run the mod again to regain native tether.

I'll add this to op when I get time.

Roam control doesn't work on my 720T when LTE is enabled in the network settings. It looks as though it's switching to a roaming service but just goes back to Sprint. The only way I've found it to work is to shut off LTE first(which requires a reboot) then hit roam.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I was playing with the hidden codes when I triggered a reactivation, reprovision, update profile, and update prl sequence on my phone. I of course lost native tether.

I remembered that idone confirmed he modified Galaxy tools to update the current telephony.db file. So I decided that rather than doing the fairly simple sqlite method again, I would try the latest galaxy tools from the playstore.

It worked perfect. With one button press, I now have enabled native tether again, and it's stable. Easy as pie and stable. Piece of cake, I love it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Sharing knowledge on slightly different topic:

One thing in native tethers favor over wifi tether router is that native is designed to auto shut off when you answer a incoming phone call or start an outgoing call. I believe this is a safety feature for things like cancer.

Imagine holding a transmitting router to your ear combined with a transmitting cellular signal all in one. Routers were not intended to be held against your ear and especially for extend periods of time. The router should be turned off when you hold it against your ear. Cell signals are bad enough and you don't want both. From all my wireless and radio waves training, it is not a good thing to do both right up against your skin for extended periods of time. Cellular and radio wave radiation absorption is something that progressively builds over time, so even though it's in the safe limit, it builds over time.. And routers certainly were not made to hold against your head.

Don't panic, but always be responsible and smart about how you use technology.

When I use Tether router and a call comes in, I always try to remember to turn off the router before answering the call, but sometimes I have forgotten and it bugs the snot out of me. With native I don't have to remember.

It may be an inconvenience to lose router when you answer a call, but it's healthier :)

I noticed there is a USB tether option under settings. Is a plan required to use that for sprint?

I am using win 8 on my laptop and can't get it to work at all. A connection comes up, drivers are installed so the device gets recognized, and I don't get a message like I do when I use hotspot at all, so that's why I'm wondering if it requires a plan. If not, does scone know how to make this work in Windows 8?

I've searched and only found one fix which I did already but still can only get it to recognize the connection as like network #2, but without Internet capability, only local.

So I spent today rolling back to NC6 from NG5 via Odin, rooting via towelroot, installing xposed framework to block the new firmware notification, and then installed wifi tether router.

WiFi does work upon reboot until I enable/disable wifi tether router. Anyone have any ideas?

That dang update kept bugging me so I went ahead and used the info from a few posts earlier about flashing the same software over itself and now I'm on NG5. Thanks for all your help. That was a major reason why I hadn't updated. I thought I was going to lose all my stuff but I kept everything. All the toggles stayed and even the native wifi. Lost root of course and custom recovery, which was keeping the update from taking. And lost the color tweaks to the notification bar but that's it.

Does anyone know how cfroot gets root? Does it replace the kernel with a vulnerable modified copy. I'm trying to understand what cfroot does to get root. It would seem to me that it would have to replace our modify an existing part of the OS to get root, which would intern make it not as secure as having the latest un-rooted OS. This knowledge will help me decide whether to just stay nc6 stock rooted for now, and whether it's worth tripping knox.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] jefbal99:
Why not just Odin in a custom recovery, then flash the SuperSU package? You keep all system security, just trip Knox, which I believe cfroot does too.

From there you can decide which system apps/services to disable.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
With this response I realize I did a poor job asking my question. I will attempt to do better. If I ever upgrade, I will probably do the custom recovery supersu method... But what I want to understand is how these methods obtain root.

Is the recovery the protector/keeper of root? Why does replacing it suddenly give you root? What is it about the recovery replacement process that gives you root? What does the replacement process do to the OS to give us root?

I'm trying to understand the ramifications of these methods. I realize I should probably be asking these questions in other threads and I will, but I thought I would give it a shot over here once.

Thank you to anyone who can fill in the holes and help me understand.

I'm glad everything worked out for you.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] jefbal99:
Sprint doesn't lock the bootloader, so a custom recovery can be flashed from Odin. From a custom recovery, you can flash zips that are not signed by Samsung/Google/Sprint. In the stock recovery, you can't flash custom zips.

From recovery, you can modify all storage, including the system partition for adding the SU binary.

I have no idea how the other root methods go about working.

I've on occasion had that problem on stock and a reboot solved the problem. I have no idea if that will help on cm11. It seems occasionally it gets hung up. I've noticed that playing with the mobile data toggle seem to increase the likely hood of the wifi freeze up issue even after mobile data is back on. Sometimes I just have to reboot.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks.

Now that I think about it, it would make since that recovery would have root authority and replacing it with a custom recovery could give the user root permission/authority.

So I wander if cf-root really does anything special. Sounds like cf-root just replaces the stock recovery also.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Manually backed out my added toggles and returned to stock toggles in order to test the "add toggles" option in Galaxy tools. Worked perfectly. Now I have a few more toggles than I had before.

Custom recoveries (and stock too, I'm sure) have their own/separate kernels. Kind of like either booting to a command line (DOS), or into a full-blown OS with GUI (Android).
