1) Yes. Grab the mk5 modem in the downloads section near the bottom of post one. Put the modem file in the CP slot of Odin application, and use Odin to flash. You may need to first ensure you have turned on the hidden developer options on your phone and have Ian debugging selected. You will also need to have the usb drivers installed on your pc. Usb drivers can also be found in post one. If you don't know how to turn on the developer options on your phone, Google around. I AM NOT RESPONSIBLE FOR ANYTHING THAT HAPPENS TO YOU'RE PHONE :)

2) I believe that is possible, but not sure how. I've not done that before. I think galaxy tools might allow you to do that.

[MENTION=4590326]bthorne79[/MENTION] what launcher do you use? I've notice the fully paid nova launcher with badges turned on will not give me unread badge on the voice mail app. I've also notice that I don't get the little voicemail notification in the upper left notification area. Not sure if that is due to nova. I switched back to touch wiz and at least I have the unread badge to alert me now.

It has been helpful that my wife now has a SPH-L720T and I can do comparisons. That is how I figured out that I was missing the unread badge on voice mail.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Ok, so now that I got my voicemail notification to work, I went back to my old way of thinking. Badges are pointless if I'm going to use notifications in the android environment. So, I reinstalled nova, froze touchwiz, and still have my voicemail notification working now :)

Yes grabb0r, you really have to read hundreds of pages in dozens of threads just to figure out which ROMs will work for you, you see, while this is a very user friendly site, you should go back and read the rules you agreed to when you signed up for your XDA account. While asking questions is a good method of learning what you're doing, the simple fact is this, we ALL started just the same way you did, and we ALL have done our fair share of reading THOUSANDS of pages in THOUSANDS of threads over time, whining will get you no where fast, Google and forum searches are the best place for you to start, then ask specific questions that are not answered in the threads you are reading if need be....geez

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] oka1:
Phones Are not just universal...... if you are going to try and use a CDMA Phone on a GSM Network there is more to it than just that.......

1. You need to be sure the ROM you flash has the ability to flash carrier specific modems .... if not then then it will not work

Also a little search with Google will find you an answer like this I did with a 3 sec search :

Apart from a wide range of technical differences, there is one key difference in the phones you buy for these different networks. GSM phones use a removable SIM card to identify the handset on the network, while CDMA phones have this information embedded in the phone.

In short, if you have a Verizon or Sprint phone that does not have a SIM-card slot, then you can’t take it to AT&T or T-Mobile (or any of the dozens of MVNOs that resell GSM services exclusively). You’ll need to buy a new phone.

And because the handset’s identification code is built-into the phone, taking it Verizon or Sprint to the other is not an option either — despite both companies using similar CDMA technology. You would need the destination carrier to install software on the phone and to be provisioned with a new customer identification number (or ESNS) and the telcos are not in the habit of handing those out — not when they can sell you a new phone instead.

But wait, I have a SIM card slot!

This is where things get interesting. If you have a new LTE-capable phone (Verizon calls these Global Ready phones), then you have a SIM-card slot. All LTE networks in the US use GSM technology, so newer Sprint/Verizon phones need to support both CDMA and GSM.

This said, your phone still may not work on any or every GSM network around town. It still needs to be compatible with the specific radio frequencies that your new network uses.

Verizon’s own ‘Device Unlocking Policy’ states that it doesn’t lock any of its newer phones, but if you require an unlock code it should be either ‘000000’ or ‘123456’.

Sprint’s unlock policy is far less friendly. You need to meet a number of requirements, including having paid off your contract, and then you need to contact Sprint for a special code.

Hope that helps.......... oka1

Don't even bother with Wifi Tether, just download Galaxy Tools (Attached .APK file) and use that handy program to enable Native Sprint Hotspot. Plus it can do alot more then just that... let me know if you need any help :cool:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Wifi tether router was removed from the play store. You have to Google around and look for it on other download sites but be careful not to get a tampered with file.

Each hotspot method has its advantage. Native runs cooler and will auto turn hotspot off when you answer a call or make a call out, so that you do not put a transmitting router to your ear for long periods of time. Native will also not work when roaming. Native auto shuts off when roaming.

Wifi tether router will work when roaming, and will not auto turn off when you answer or make a call which can be handy if you are using the speaker phone to make the call (not putting it to your ear ;) ). Wifi tether router runs hotter (makes your phone very warm). Lastly, WiFi tether router supports adhoc(if you need that), and native does not.

I think both are good to have.

NAF flashed to PagePlus 3G

OP lists

in the version list, but my L720TVPUBNAF (Software/Baseband/Bootloader version) is running Android 4.4.2. Am I confused, or my phone FUBAR, or was that just a type-o?

I bought this (my 1st smartphone) phone June 2014 pretty much as-is today...rooted with SuperSU, BusyBox Free, Root Browser, Uninstaller Pro, MSL Utility and flashed to PagePlus 3G (Verizon MVNO). Been pretty solid.

Thanks to this valuable thread, I quickly installed Titanium Backup, and more recently used Flashify to get TWRP recovery running and backup (that is a nandroid, right?). Installed GalaxyApps and used it to do a SIM UICC Unlock and change the mps_code and sales_code from SPR to XAS like my default_code was already set. I have Odin3 v3.09 and the Eclipse Android SDK on my PC, but haven't really used them. (Kies has never been able to connect to this phone, but I don't think I care.)

All that said, I have a few newbie questions:

1) OTA notifications keep coming. I got rid of them for a while by deleting the OTA file (if I remember correctly), but they re-appeared a while later. GT's Delete and Disable Sprint Update buttons don't seem to do the trick for me. I don't think I want those OTAs, as I'd lose my PP3G flash, right? I honestly have no clue what the seller did to flash it to PP3G.

2) Can I (should I?) manually update to OA3 without losing my PP3G settings? Do I need to downgrade the modem to MK5 like I've read for post-NAF updates to do that?

3) I read somewhere that this phone cannot be used with the recently available PagePlus 4G (Verizon) because of the physical radio. Anyone disagree and have experience/instruction on that?

You can try Ktoonsez kernels, I have run them on my S3 and my S4, but I don't overclock.

They come with the Ktweaker app to overclock though.

Ktoonsez kernel
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I'm pretty sure it was 4.4.1, and I don't think it's a typo; however, I have not had NAF for a long time so I can't be sure. Perhaps someone else can validate this.

I am not familiar with page plus but I would say that if update to OA3 you will likely lose your settings. The OA3 OTA may set you back to Sprint and lock the sim.

It your choice.

Since OA3 rom is not deodexed and I really want to be on a deodexed rom, I restored my NG5 backup after updated to OA3, now wifi is not woking. It seems NG5 rom wont work with OA3 modem?

L720tvpuboa3

Hello all. I have been looking for a deodexed L720TVPUBOA3 rom or just a copy of the rom that I can deodex my self. Now the link in the op is really slow for me, so I did some digging online and I found this.

http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=sph-l720t

I downloaded the zip file and it doesn't look right to me. there is a Kernel.tar.gz, a Platform.tar.gz, and a couple of read me.txt's. Now I'm no programmer so I'm only guessing here, but I think this is an un-compiled rom. Was wondering if anyone could take a look at it. I have attached the 2 txt files.

That's the kernel source code (compressed) that Samsung is required to post to comply with the GPL license requirements in order to use the Linux kernel. gz indicates gzip compression and tar stands for tape archive (though you don't need to store it on magnetic tape... :silly:). It's a compressed archive file, in other words.

stock OA3 rooted and working

I had a stock rooted (odexed) NAE rom in mine, and when sprint pushed the OA3 update to me the other day, it broke WIFI, and ultimately the entire phone. After many struggles, I eventually pushed a stock NG5 rom back to it with Odin. But when it came up, Sprint pushed the same update to it, and it broke WIFI again. So I rooted the now OA3 rom with CF-Auto-Root-jfltespr-jfltespr-sphl720.tar.md5, used DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V2.5.zip to get rid of Knox, and everything worked, except WIFI. So I pushed the modem.bin and NON-HLOS.bin from the OA3_extras to it with ODIN, and now everything, including WIFI is working. It is rooted, but not de-odexed. However, the GSM features in "network settings" are greyed out. I am certain that those were not greyed out prior to getting pushed to OA3. Perhaps my experience will help you to get WIFI working again. Does anyone have any thoughts on getting the GSM features to work again? I am leaving the country for two weeks, and was planning on using a different SIM.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I'm no master of flashing, but Here is an observation that I hope will be helpful to you.

You said originally you were on NAE. NAE is not a SPH-L720T firmware. You also mentioned a non triband 720 tar file in your post. Another indication that you're phone is not a 720T our it had the wrong firmware on it to begin with.

Here is the full list of SPH-L720T firmwares revisions:

Tap the list to go to the Sprint site for validation.

MK5 = 4.3

NAF = 4.4.1

NC6 = 4.4.2

NG5 = 4.4.2

NK1 = 4.4.2

OA3 = 4.4.2

That being said.I'm glad you got evening working.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] andrewt2323:
definitely a 720T

It certainly could have been on NAF when the mess started this week. The system was not bootable, so I was going by what I could see on the recovery screen, which is VERY tiny. But I have the original box, and the model on the box shows SPHL720TBK, and the boot screen was always the Sprint Spark screen.

Regardless, it does work, except the GSM features being greyed out, and I am still looking to solve that. Thanks for your reply and the information!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] shadowcliffs:
Do you mean your phone is on OA3? Then no wonder WiFi works after you flash everything OA3. My observation is that once your phone is upgraded to OA3 bootloader, you can't revert to any earlier rom without WiFi issue.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
And this is why I don't ota
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I suspect that most of the ota problems occur when users have been flashing mods to there phone prior (such as deoxed). If a user is original stock meaning they have never flashed a mod and then flashed back to stock, I suspect ota rarrely causes a problem.

That being said, I see the wisdom in what your are saying and completely agree. ;) flashing the entire firmware would be more reliable.

Just my two cents worth :D
