I guess I can take the blame for the wording for sure. My two younger sons are 720t my older son is 720. Guess I should have said that instead of non spark, however that is exactly what they call it on my sprint phone profile page. Younger boys says (s4 sprint spark) older says (s4 non spark) in parentheses.

Stock ROM with towelroot. Although I am certain it worked after unrooting for warranty repair.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks for the spark/720 clarification. That makes sense to me now.

I am still confused on some points though. Can you please confirm that you successfully tried these hotshot instructions on a stock 720T and the apn settings were no greyed out?

And are saying that apn was locked before unrooting, and that unrooting unlocked the apn settings?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
nc6 hotspot

I did not check the apn setting pre initial root. I towel rooted and used a wifi app. I saw the previous mentioned instructions and tried it while already rooted with success. I then had to unroot for repair and did. After repairs I did not reroot. I went straight to the apn setting and success.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. Hmm... I wander if the repair techs unlocked your apn.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
Unless I worded wrong again it worked prior to repairs...and after

I'm stock NC6 with CF Auto Root.... My APN is greyed out.

Have you ever flashed anything to your 720Ts and then went back to stock at a later time?

This works! Download the telephony.zip, extract and copy in place of your telephony.db after renaming your telephony.db to bak just in case something goes wrong. Location to copy to is in the OP. Just tried it and it works perfect on my L720T !!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
Nothing extra.

Rooted, stock nc6, nothing extra.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] VandyCWG:
the download of the telephony.db worked for me. I could never edit my greyed out APN data.

I did rename my telephony.db file to telephony.db.bak (just in case).

Another question, any way to add a hitspot toggle to the notification toggles? (Same thing, would love a flashlight toggle, and mbile data toggle)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] klabit87:
This works for mobile data toggle.

http://xdaforums.com/showthread.php?t=2342370

And the torch requires modifications to SecSettings.apk and SystemUI.apk as well as adding them to the toggles in the notification panel.

Also T-Mobile S4 was not able to add mobile hotspot. Verizon is able to so it may be worth a try.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
There is a thread using sqlite and changing a value in settings storage. It works too
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] jdonmc1948:
You don't have to change apn. Just replace telephony.db with the one here and reboot.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I must saythat I have thoroughly tried the sqlite settings.db method on 720T multiple times with various methodologies and it never worked for me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
OK. Here is my assessment thus far. And keep in mind I'm stock NC6.

I tried using this modified telephony.db with no other changes except a reboot (not sure if that was necessary) and it worked. Native Hotspot can now be activated. There was no need to do any of the dial codes or to run uncertified apk's (no need for msl).

Now I need to look around to see if there were any negative side affects.

One thing I need to do is restore the original telephony.db, activate wifi tether app, do some speedtest from connected device. Then switch back to modified telephony.db, activate native hotspot, do some speed tests, and compare...In order to validate efficiency. I'll post results when I have them.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] jam0688:
The sqlite method to add the mobile data toggle to the notification toggles does in fact work because it worked for me and im on nc6. You have to make sure you you add it in the notifications_active_app_list and not the other ones because if you add it to the others it wont work. Ive got the bought version of sqlite from the play store so it could be the one you're using to.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I should clarify that I was referring to trying to modify the settings.db tether dun property to get the native hotspot working. That never worked for me.

I've no experience with trying to modify settings.db to get toggles working.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I've completed seven native tether speed tests with modified telephony.db versus seven speed tests using wifi tether app and original telephony.db. The results are a solid average increase of 3mb down and .25 up usjng wifi tether app and original telephony.db.

I also tried seven speed tests using wifi tether with the modified telephony.db the results consistently matched the results of using native tether with modified telephony.db meaning the speed was consistantly slower than wifi tether app with original telephony.db by 3mb down and. 25mb up.

Also native tether app only allows 8 devices to connect, and I THINK wifi tether app allows 10.

I will perform speed tests again tomorrow from another location.

Hi All.

I understand that there are still no International unlock solutions for this phone using software. Is there any other way? Flash box etc.

Thanks

There doesn't seem to be much discussion at all on XDA about unlocking this device.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] VandyCWG:
No way to unlock the T version.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
Couple problems I had with wifi app was constantly having to turn it on/off to work, would disconnect when screen went off no matter what settings and heat after a little bit of use. Native solved all these problems. That said 3 extra mb is interesting. Good post.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks. I've never had a problem with wifi tether router app turning off when screen shuts off, and leaving the screen on will heat up the phone more than anything else. I have had problems with Internet/app cutting out on some channels.

Try switching channels (probably to 6 or to 1) but go through them all and do a router test turning your screen off after channel change. It takes patience

Also make sure you have "prevents stand by" checked in wifi tether app. I always have that checked.

One more thing...May seem like a strange question, but what encryption method are you using in your app?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] muddogknls:
Tried all of the above but worth a shot again
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
OK. Good luck. I have also seen intermittent connectivity / unstable issues with some encrpyion methods on some routers. I use WPA2 on wifi tether router app.

You may also want to take a second look at all the wifi tether router settings I have listed in the op.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] DroidJer:
Anyone know how to change the touchsound? In settings, there's an option to disable it, but I don't want to disable it all together. I just want it to get rid of this stupid water drop sound. I'd like to change it to the stock touchsound on CM11, which sorta sounds like a leathery thud.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Ok I've completed 3 more speedtest repetitions from the original location. This time comparison results actually showed native tether with modified telephony.db slightly faster than wifi teather app on all 3 comparisons.

Summary: I'm convinced they perform the same. No significant consistent difference.

Main thing to remember is that native allows 8 connected devices and I think wifi tether app allows 10 devices.

Wifi tether app also allows more encryption choices. Native only allows wpa2.

That's all I can think of for now. Will update op when I get a chance.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] gersrt:
Well if you were searching for 2 days you would have relized that the spt-720t can't be unlock and by the looks of things may never be unlocked due to the lack of support and the fact its been available since last January. There doesn't even seem to be a flasher box available to unlock it. So I think we are **** out of luck. I hope Im wrong as Im stuck with one here in europe which I thought could be unlocked from reading that the Sprint S4 could be internatioaly unlocked. If there had been a sub forum for our device I propbably would have relized before hand.

is this a rule? Just wondering...and yes, I have been searching for two days, and yes, i did read that this model couldn't be unlocked along with five other threads, saying it could..so that smart ass reply was not needed lol. Gerst...

Although, some of these posts are so cross posted, that is hard to even figure out what device the instructions are for. These forums have definately changed from just last year. I guess the former moderators..have moved on..

Galaxy S4 Kindle

Anyone experiencing issues downloading/syncing books from Kindle?

I've got the S4, rooted via towelroot, this thread has been absolutely fantastic for getting the S4 rooted and tethering working without tripping Knox. Also ran the SD Card fix.

I've opened a ticket with Amazon but still the kindle app will not download. I've tried both the Samsung branded Kindle App and the Play Store version and still a no go.

I get the following error:

"A network connection is required to download your Kindle title. Please connect to a network and try again"

I can view Youtube videos, FB, any web page from Chrome or the builtin browser, ES File Explorer can access shares, so I think the error is misleading, plus the content shows in the "carousel".

Hey all, my FIL has an S4 (NC6 720T). He was having call quality issues as well as not receiving calls( in all areas between NC and AL so we know it isn't service related). He went to a Sprint store and all they did was turn 4G LTE off and did nothing else. Now he is dropping fewer calls but the call quality is terrible, and when you talk to him there's a lot of echo. I did all the checking I could think of, I did a ##72786# reset,made sure the ICCID matched, it did. What I'm wondering is if anyone here thinks it might help if I ODINed the stock file ( NC6) back into it. I have an S3 so I haven't had much experience with the S4. Thanks in advance for all your help..Phil

Hey I read through most of the thread and tried to search for what I am looking for but not sure if I used correct search strings. I have the sph-L270t on 4.4.2 ( Nc6) , stock rom, used cf root successfully tonight to root and twrp recovery.... Both flawless. Now on to the Hotspot. I want to confirm that the WiFi tether router app still works for this model /version? I have no problem paying for it but before I do I want to ensure it works. My main reason for rooting is the WiFi Hotspot functionality.

As well as root Explorer /setpcu/ti backup (and the fact that I have started learning to develop Android apps via Eclipse)...

So... Does this app still work for that? I tried foxfi and it did not work, I got the you must purchase Hotspot upgrade pop-up.

I just don't want to spend the money and have the same thing happen.

If it does not work how might I get WiFi Hotspot functionality ?

I had tried the qbking77 method of replacing the 2 files and soft bricked the phone with that method. Best buy now has samsun reps in store who reflashed my phone free thankfully. I don't want to do that again if need be.
