Sprint s4 sph l720 Octos CM13 6.0.1 help. - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

So I have a sprint s4 onrunning octos (cm13 build) on 6.0.1. I have the OK3 already, as I came from 5.0.1 already using OK3. My question is, what modems can I flash BACK to? Better yet what firmware can I downgrade / flash ? I am having the worst time trying to get my network settings to work. The APN settings are COMPLETELY GONE. There is no way for me to edit them. And the best I'm getting of service is 2 bars of 3G MAX, when I usually get almost full bars of 4G here at my house. I struggled to even get 3g working. Can anyone help me out?
Sph l720 sprint running Octos CM13 6.0.1. MY PHONE IS ON STRAIGHT TALK. I REPEAT MY PHONE IS ON STRAIGHT TALK. THE SERVICE PROVIDER IS NO LONGER SPRINT IT IS STRAIGHT TALK.
But for some reason, when I was having the phone activated I was having trouble getting the sim to work. But they told me that was because it did not take a sim card with straight talk. Also they never told me to use the provided network access code. The phone was literally sitting there for 3 hours NOT ACTIVATED. Because they said it was in progress. I asked if it was taking so long because of the sim card not being inserted. They told me no. But for some reason as soon as I put in the sim card BAM IT WAS ACTIVATED. could anyone please help me out in some way

[Q] Unlock SPH-L720 Baseband L720VPUFNG2?

Has anyone successfully unlocked the SPH-L720 from Sprint with this newest firmware? I found instructions on another thread for unlocking the L720, but they are for Android 4.2.2 and do not work with 4.4.2. When I attempted to downgrade the modem, it bricked the phone. I've managed to get the correct firmware re-installed and un-brick the phone, but now I'm back to square one.
The phone is rooted, I just need to carrier unlock it from Sprint and remove the CDMA lock so that I can use a GSM sim (attempting to use the phone with NET10 which uses T-Mobile/AT&T compatible sims).
I'm having the same issue here. Let me know if you got through. I want to use my Galaxy s4 outside the USA on a GSM network.
same issue
I need to know also my contract is about over will sprint really unlock it for me I am rooted or can I go to a MDC baseband version and do the unlock codes....... please help ty

Bumping this to see if anyone has figured this out?
I've got a GoogleFi data only card and would love to get my S4 back online but it seems I'm SOL since I'm on L720VPUFNG2.
Someone on reddit said they figured it out but hadn't provided the details (nor replied to PMs), I don't want to brick my phone as it's still an excellent backup.
Is unlocking an L720 on NG2 possible?
Please I need this too
Have you guys tried the unlocking thread in the General section?

How to restore cellular service

I've recently installed Lollipop GPE 5.0.1 and noticed that I no longer had cellular service. I then reinstalled stock 4.4.2 (NG2). I still don't have cellular service. When I go to Settings/Connections/More Networks/Mobile Networks, the Network Operator option is greyed out. Also, the cellular icon has a red X over it. Any ideas how to update the cellular service? By the way, my SIM is for RingPlus (a Sprint MVNO) which has worked fine on this phone prior to my installing Lollipop GPE. Any hints would be much appreciated
Update PRL and Profile in Settings/System Updates. If that doesn't work, dial ##72786# in the dialer. This did a network reset.

Having the same issue. So the only way to get an update prl is through a touch wiz rom right? I tried Sacs and its stuck on trying to connect. then went to dialer and there is none. So i tired a different rom with dialer and it says i have no mobile service. Anything else I can do?

Will that give me knox? I am trying to avoid that if possible. Also do you have a link to a stock rom.

Android Development... All ROMs are there. Why are you trying to avoid Knox? It won't prevent you from doing anything.
Sounds like your baseband is not compatible with your ROM/bootloader..

not sure this been asked yet

I have my Samsung s4 sprint version rooted unlocked etc all that jazz and on red-pocket carrier. I used their sim card now the phone don't recognize the sim card. Also I keep having issues with the google play services error. Also bad battery drain. I am on the stock deoxed od2 rom with stage-fright patch.
so my question is for all those looking and not answering or trying to.
1.any ideas why this phone wont recognize the sim card?
2. any ideas why I have such bad battery drain?
3 why does my g4 still say it has stage fright vulnerabilities if I did the patch/fix.
4. what could cause the google play services to not work.
5. what keeps a s4 from flashing a boot animation?
im shocked no one has a answer or idea

First thing I would try would be to flash pure stock and make sure your sim is recognized/activated

1. Sim card could be bad, hardware could be bad.
2. There are a million reasons, check your battery usage to find which apps are using the battery. You can also try getting a new battery.
3. A new vulnerability has been discovered that has not been patched yet.
4. Again a vague question that could have many answers.
5. Samsung uses qmg format, if you hop to my Wicked X thread in post number 3 there is a converter that allows you to use zip format.

SPH-L720T stuck on Global??

Hello everyone. I recently bought a few Galaxy S4's to resell. I kept and unlocked one, then sold the others on ebay. One of the buyers just contacted me and told me that they cannot get the phone working on their sprint account because Sprint says the phone is stuck on global mode. What is global mode and is there any easy way I can walk them through correcting it? I dont rememebr seeing a global setting in the *#0011# menu.
Thanks in advance.

I would tell them to Odin the stock software from www.sammobile.com that should reset everything to stock. Global mode is where it is unlocked and can use either a CDMA or GSM signal (as most of the world uses GSM not CDMA, hence the name global).

Thanks for the reply. I thought I used ODIN to format this phone before I shipped it, but I could be wrong. How can I make sure that the phone is able to work on sprint before I try to sell it again?

Yes, it does that as well... As for the last question, I don't know. Kind of hard to tell on an unactivated phone. You could try Freedompop, it's free and they use the Sprint network. If it works on there it should work on Sprint.

Sprint Galaxy S4 (SPH-L720) WiFi Tethering??

Hey guys,
I have a GS4 (Sprint - SPH - L720) running Lollipop - 5.0.1 and not able to even find the tether option. I downloaded ES File Explorer to try and get it working. It turns on the wifi and is even detected by another device but it doesn't want to connect. Any idea what's going on??
Thanks for any help!

You have to pay for the service unless you have a ROM that has it hacked, the only one I know for sure that has it is my ROM, Wicked X.

Thanks for the reply.
I live in Australia and purchased the unlocked phone from Hong Kong. It works ok but still has some GPS locking issues. I don't know if this has also got to do with paying for the service?
But since im in Australia not sure if it would work.
Would your ROM work well with my GS4? Is it stable??
Cheers
