Sorry, rooted NC6.

UPDATE: Not sure what happened but when I woke up today I got error com.android.phone stopped and no signal. Possible cause by telephony.db?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I don't think you have anything to worry about. That exact same error has been happening to my phone several times over a few week period. It's a real pain. You can't really use your phone until it stops, but if you wait it out (sometimes a few hours) it goes away. I called sprint and they said that they could tell my tower was being upgraded in the area and that was probably the cause. It always clears on its own after awhile (some times hours) and typically doesn't return for days or weeks. Sprint said the upgrade normally takes a couple of months and may happen several more times. Supposedly they are upgrading tower to spark :) buy what a pain in the mean time. I told them that my phone is useless when this is happening, sprint gave me a out of service credit :)

ADDITION: I also tried the clear phone cache solution you will find if you Google around for this error. Clearing the phone service cache never worked for me. I just had to wait it out until they were done playing with my local tower. The problem always went away on its own.

SPC/MSL

I am trying to use this phone on Page Plus, but I have not been able to change the MSL to 000000 without the phone denying the request. I have tried DFS, CDMA Workshop, and QPST to attempt this. Is there any way to change the MSL on the NC6 firmware? Getting my MSL was easy, but changing it seems to be blocked by Samsung. I have never had a phone refuse to let me do that. I'd prefer not to go with a donor phone.

Native Hotspot fixes

For anybody having trouble getting native hotspot working, through some trial and error I have figured out a few things that might help. First off, I highly recommend purchasing the paid version of SQLite Editor. It's totally awesome. Besides the hotspot stuff, I used it to modify my toggles and it works like a charm. Back to hotspot stuff - like others, I was not able to get Native Hotspot to work with the Galaxy Tools app. I was able to get it to work by copying the already modified telephony.db referenced in the OP. But I wanted to figure out why the Galaxy Tools app wasn't working. So I did "Enable Native Hotspot" in Galaxy Tools app, and then looked at what it did to telephony.db. What was happening is that it was blanking out the column named "current" for all the APNs except "Global Roaming - SPRINT". When I looked at the backup of telephony.db, "current" was set to 1 for "Global Roaming - SPRINT" as well as the last 4 entries in the APN list. Apparently the "current" column has to be set to 1 to activate an APN. When I set the blanked out values in the "current" column back to 1 and rebooted, native hotspot worked!

So the moral to the story is, get SQLite Editor, and edit the telephony.db yourself. It's a breeze with this app. I believe the instructions are referenced in the OP (separate link). But basically all you have to do is navigate to the folder where telephony.db is, and using SQLite Editor, add dun parameter to "type" column of the last two entries (APN2 LTE internet and APN2 EHRPD internet), and make sure "current" column is 1 for last 4 entries. Then just reboot and you will be good to go!

I also highly recommend adding a WiFi Hotpot toggle to the notification bar. Again, it's breeze to do using SQLite Editor. There's a link to the instructions in the OP as well. If you get an error trying to edit settings.db, get TB Restore Fixer app from play store and run it. You should then be able to edit settings.db.

Good luck! :)

So you were able to Root running NG5 with CF Auto Root from the following page??? http://xdaforums.com/showthread.php?t=2291827

And if so, did you take the OTA for NG5 or did you flash up to it through Odin??? Ive been looking for the tar file for NG5 to flash through Odin and cant seem to find it....Can you point me in the right direction??? I bought my mom an S4 and it came with NC6 baseband...She keeps getting a notification for an update.....Im assuming its for the NG5....

Im an HTC user my self and am very familiar with that process for rooting etc...But this Sammy is a bit different for rooting/flashing...

I'm afraid you're out of luck. With the recent updates, they have closed the hole that allowed editing of the APNs (telephony.db) withou root. Unfortunately, you will have to root to get hotspot now.

How do you update the prl in cm11?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
You need to make a nandroid backup of CM11, clean flash a stock TouchWiz ROM, update the PRL, then wipe and restore CM11 from nandroid.

Why is there no way to update prl on an aosp rom?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
I don't know for sure, but from what I've learned, probably because it involves proprietary/closed source binaries for which no sourcecode is availble, and would be illegal to copy from the OEM ROM.

Lots of times the drivers are not even the work of the phone's manufacturer, but the maker of the chipset (ie: Broadcom), and they tend to sue you when you do stuff like this.

Newb to 720T (NG5) and searched through the thread, but still not sure as there are some conflicting posts.

So,

1) will Sprint do GSM/SIM OTA unlock to use with non-US SIM with overseas operators?

2) if so, will using an

overseas, non-US SIM

allow roaming with US operators?

I have an overseas SIM that roams on AT&T and I'm using it here in the US for incoming free SMS.

If 1) is a yes, I'm willing to do a backup before and after - just point me in the right direction. TIA
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
If sprint did you would NOT be able to use the phone with an international Sim can while in the US. You have to be overseas to be able to use the unlock. Sprint will never Domestic unlock your Sprint phone.

Native Hotspot toggle is hidden by default on 720T, but you can unhide it with a mod. Look for toggle mod instructions in the op.

1. Curennty running NC6 baseband...Going to Falsh L720TVPUBNG5_L720TSPTBNG5_SPR.zip through Odin

2. Run CF-Root for this site http://xdaforums.com/showthread.php?t=2291827

I simply used the version for this model listed at http://autoroot.chainfire.eu/ and it worked fine. Previously I had used towelroot, but NG5 made Towelroot ineffective. I took the NG5 update OTA, then used cf auto root afterwards. Incidentally, though there were lots of warnings about the yellow triangle, I don't see one; it's possible that the Sprint splash screens are hiding it though.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] hllywd:
Ya I'm sure it's a 720t. And both my build and baseband are ng5. We'll the way I play with my phone, I'll probably do a couple more clean installs over the next couple days so maybe it will work out.

Simple rooting with ODIN, TWRP & SuperSU

I'm sure others have done this rooting method before but because it wasn't listed in the OP:

1) Get TWRP tar for jfltespr (2.8.0.1 is the latest as of this posting)

2) Download supersu zip installer to either internal storage or ext SD

3) With the phone in download mode and Odin 3.04 set to NOT auto-reboot all other options UNchecked, flash TWRP into PDA slot. When done, remove battery and USB

4) Power up into recovery. If it's still stock recovery instead of TWRP, just redo step 3

5) Flash supersu.zip

Done. The phone is now rooted. After rebooting system, open SuperSu and if you want to fully disable Knox, say yes to the prompt.

This is the method I use for most of my Galaxy devices, and I successfully did this on my son's stock L720T NG5.

EDIT: Yes, it will trip the Knox warranty flag.

Just wanted to say, thank you for the thread. I would like to reach out to anyone that is interesting in developing on this version of the s4. Perhaps we can start a donation bounty for them, and/or we can get a IRC room and some testers.

Summary of my system: I am rooted with k1mu SafeRoot and have about twelve system apps (including the touchwiz launchers) frozen with Titanium backup. I use nova launcher as my primary launcher. I wish to remain rooted and according to things I read on the saferoot thread, I cannot receive OTA updates while apps are frozen, yet I received new notification this morning on my phone that says "System Update Downloaded. Touch to install".

I didn't think I could get OTA notifications with system apps currently frozen. I'm afraid this might be the 4.4 update and I don't want to install it... because from everything I've read, I will lose root indefinitely.

Can anyone tell me if this notification that I got is the 4.4 Kit Kat update? and if it is, how can I hide the notification, so that I don't accidentally launch it at a later time with frozen apps, and mess things up.

I read the thread and kind of you to provide the link. I froze FWUpgrade. Not sure what SDM stands for, and I don't see a SDM in the list but when I type SDM in the filter it brings up a service called "System Update 1.8.8". I froze it also, assuming it's the right one.

I restarted the phone and the "System update downloaded. Touch to install" notification is still on my screen.

1) Is there any way to get rid of the notification after it has already spawned? I don't want to accidentally click on it at a later time.

2) and Is there any way to tell what the update actually is before launching it? Maybe it's not 4.4 and I can launch it.
