It's fantastic that you have a build up and running and it even shows the baseband which means you at least able to make and receive phone calls, unlike builds for other devices I've seen that show that as unknown. It's my understanding that it's super early in development which means a lot of things are not working, what's working and what's not working in your build? Maybe create a thread, I believe you'd be the first with a marshmallow build for our S4
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] EngineManShawn:
I'm thinking about switching to cm mods. Also maybe getting away from twrp. It's always an issue with myS4 to get a decent mod working correctly. Plus seems that everything I paid for apps are for cm mods..
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
From what I can tell is everything works my s4 is a WiFi device only now since I'm not with sprint anymore and the one I built for my g3 shows baseband unknown but everything works calls data mms/sms if someone wants to be a test bunny for calls and data I would be more than willing to make a thread
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] EngineManShawn:
Yes but I would like a nice colorful custom ROM with all the trimmings. I just can't ever seem to get all the features running. Like wifi

Will the sprint download work for boost mobile?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Yes it will you might need a boost apn fix here is the latest one I know of our boost testers use it

https://copy.com/NiJiULg31YXsNin9

Flash in twrp like any other zip
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] messy9867:
This APN method is it delete able when flashing back to stock or flashing to another rom? Maybe another ROM that doesn't require APN?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Anytime you wipe system and data it wipes rom apps accounts so yes but I'll tell you just about every rom will need it UNLESS it has been modified for only boost/vm which will not happen. Devs normally don't go that far our team did for the spark s3 d2lterefreshspr because it has 3 carriers we created a aroma installer that will allow you to pick carrier and it will set the correct apns and data drove our dev nuts getting it right fix one broke another. We made the device tree from scratch. Cyanogenmod will never support it because its consider"prepay" device even though sprint is moving to the spark networks and lot more devices will start showing up with it

Hey fellas, lurker here looking to not end up with a bricked 720T.

I've been running into some jankiness with LTE handoff and other issues while running 5.1 GPE by Danvdh with NG5 baseband on FreedomPop (Sprint MVNO). I've been doing a lot of reading about moving on, but I'm stuck on a handful of questions:

1. Since I'm still on NG5, which is listed as the baseband for 4.4.2, can I safely downgrade back to KitKat without complications?

2. If I stay on LP and go with a TW ROM, I'll need to update to OH1, correct? Is there any reason to update the baseband for non-OEM firmware?

3. I don't expect a full list of compatible ROMs, but can you throw out some of the more popular ones that are solid daily drivers for the 720T? I've been eyeing Octos, Wicked X, and SlimRom.

Any help you can send my way is much appreciated. :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheHumansAreDead:
I'll give you CM13 build a test ride with Ring+ voice and data. Are there APN issues with it? I'm currently rocking BlissPop on 5.1.1 with very few issues.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] mattzeller:
Of you have a flashable APN fix it'll be fine, but there are Bluetooth issues as well as voice to text issues
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheHumansAreDead:
Thanks for the heads up. Both those features get used daily for me. If and when there is a new build, I'd be willing to help put it to the test if needed.

There is still no mention of working 5.1.1 ROMs @ the beginning of this thread. Does someone need to contact the OP to share this info so people don't need to look so hard to find it?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
OP here. Sorry, been busy lately and had a couple of medical family emergencies. One yesterday. Praise the Lord everything worked out ok.

Moving the discussion along. Here is a little history and how this thread works...

When I started it, I was an android noob. I've learned much since then, but still consider myself a noob compared to many folks on here.

I'm a stock user with root, and some patches/hack experience. I've never flashed any ROMs other than stock upgrades with Odin. I also have experience with several root methods, and some different phone models and carriers

I originally started this thread to get beyond android noob, learn how to root my first gs4 (which is still my primary phone), and just learn as much about my phone as possible so that I don't break it (they are expensive for me).

Info was all over the place and it was hard to learn at first. I wanted to bring everyone interested in 720t and particularly sprint 720t together in one place so that I didn't have to go all over the place so much, and could learn faster. I also figured others would benefit as well.

I designed the first post to be a summation of all the major things reported and learned across the entire thread as much as is possible.

The point is that since I'm not a master of everything and can't do the research for everyone on everything, it's a team effort, and I rely on others to post knowledge/goodies for the operating post.

So...I watch the thread and collect working ROMs and other knowledge, and sum them up in the op as best as I can for all.

If you want to post some good working 720T 5.1.1 ROMs and resources, I'd love to add them to the OP.

Thanks all.

Love the thread, it's a wealth of information for all SPH-L720T owners.

I can confirm for this thread, Blisspop v4.0.3 Official 20151112 jfltespr (Lollipop 5.1.1) runs as smooth as butter on our sph-l720t, with 3G and LTE service on Ring+. I had to edit the APN settings for Ring+ to get the data working, and I posted that info to this thread as well. http://xdaforums.com/showpost.php?p=63920348&postcount=3017

Triband vs non Triband S4

I a wondering if a Triband sph L720T will work better for me then a L720.

I use Freedompop, which is a data only service, and live on Long Island, where there is some spark service.

I currently have a rooted Galaxy S3, which I love, except data speeds are on my S3 are usually too low for decent VOIP.

I am hoping that a Galaxy S4 will improve things because of the additional LTE bands.

I imagine a Spark version would be best.

But are there are downsides to the spark enabled version relative to the non spark S4?

Thanks!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Getting a normal L720 now would probably be hard due to sprint moved on to the Spark network. When I got my S4 I was thinking I was getting the normal one ended up with the Spark one at the beginning of this phone rolling out custom roms was very slim picking someone on the Cyanogen team merged all necessary blobs in to the jfltespr trees so all custom roms using the jfltespr you will be fine with flashing so making a list is ehhhh not really needed.

As for the cm13 build I did had some issues most would not say its a daily driver.

BT issues, camera, didn't test nfc

Calls and data worked lets say that haven't had a chance to do a new one yet been busy with work and getting a server working again
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] HunterAsh:
I am in a bit of a pickle. I am currently running the latest Snapshot of CM (released on 2015-11-16) and I have nothing but issues with my signal.

I lost the T and the spark when I flashed CM a couple of months ago, along with that, my GPS is completely unreliable, my signal constantly drops. When I reboot my phone, I have no connection to the network and to reestablish the connection, I have to make a call which sometimes works.

One of the mods on the CM forums said I had to update my baseband and to just google it for my device, however all the sites I have been to seem a bit shady and no other help has been provided.

After I used the file provided by tyxavier13 in this thread, I had to reflash the entire device and reset it because of issues with everything crashing at once and now I can't get anything above 3G.

I need help. I want to stay on CM but my device keeps acting up. With the way it is, I can't rely on it anymore and I NEED the GPS for work.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Harry56:
Are you implying that a normal L720 would be preferred to the Spark version if I could get a normal one?

I won't be using cellular voice on the phone, so no issue for me of being able to use voice and data at the same time.

If I understand your post, the various roms are available on both the regular and Spark S4.

The faster potential speed of the spark version is attractive. I don't care about simultaneous voice and data. Are there any downsides or issues that might make the non-spark S4 preferable?

Thanks so much!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
I've had both phones and there is very little difference, I'm not in a Spark area so the only difference was Wifi Calling on the L720T. I say if you're not in an area that has Spark capabilities, save some money and buy the L720, that's what I did.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Things are much better now. Thank you my friend.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
What baseband are you using? I ran OctOS for months with both NC6 and OA3, and the latest iteration is really great. Had to go back to stock because I'm giving my S4 to my wife soon (getting a work phone I can use tomorrow, bye bye iPhone....) Flash a stock ROM, update PRL and profile, get a GPS lock, then flash OctOS (don't turn GPS off). That should do the trick. Only thing that didn't work for me was the compass. Signal reception actually seemed better than when running a stock Samsung ROM.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] HunterAsh:
My baseband version is L720TVPUCOF1.

I would update it but I don't know where to get a trusted copy of the firmware nor do I know where to get a official stock Samsung ROM.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
OF1 is new enough that I wouldn't worry. You can find links for a stock/rooted ROM on the first page of this thread.

I had the latest but then I switched to the latest snapshot of CM Recovery. Neither let me flash the ROM.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
First off you need to get odin working stock firmware link was already posted sammobile

Yes you can flash only modems but it has to be done in odin mode you would have to extract the tar file to get the modem on the afh link I posted the modems are in the extras.zips

Also what firmware was you original on after a curtain build you was unable to downgrade I believe it was the oa3.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] mattzeller:
That last one, you need to extract the file from the zip, then flash via odin

Recommended Recovery // root method?

Ready to root my new (to me) 720T and wondering which recovery to Odin as well as what root method.

The phone is stock Lollipop 5.0.1 - OH1

What recovery do you recommend with the OH1 version?

IS CWM or TWRP a better choice?

Should I use ODIN to flash TWRP / CWM and install Supersu zip onto my SD card?

Also: If I flash TWRP / CWM from ODIN, can you clarify how I prevent the stock recovery from writing over TWRP on the first reboot?

I realize many variations of this question have been asked many times.

I'm just a Noob having a hard time sorting through this thread to where things are now....

Thanks so much....

SOFTBRICKED Installing TWRP

My SPH-L720T softbricked while trying to install TWRP via ODIN.

I CAN access download Mode.

When I power the phone on, I get this error message,

"Firmware Upgrade Encountered an Issue. Pleased select recovery mode in Kies and try again."

When I try to use KIES, the phone is not recognized. When I try to download the firmware through kies for emergency install, it asks for serial number from inside battery compartment, but there is no serial there - just Hex and Dec numbers which Kies rejects.

This is what I did to get myself into this trouble....

Opened ODIN 3.09 in a windows 8.1 Desktop

Put SPH-L720T with OH1 firmware in Download mode

Connected phone to computer, observed com connection made in ODIN.

In ODIN, PUt TWRP 2.8.4.0 into AP box (NOTE, I could not find newer version in JAR format)

Unchecked reboot in ODIN.

Started ODIN.

Passed.

Disconnected Phone

removed and replaced battery to exit download mode

Tried to go to recovery mode, but phone rebooted instead.

Powered off, went to download mode, and found stock recovery.

Went back to ODIN and tried to do over the procedure.

This time, ODIN FAILED. Uh oh.

When I powered up the phone, I got the error message described above referring me to KIES.

I can enter download mode, but not recovery. Kies does not accept my DEC number as a serial number.

How do I fix this problem? Reload entire firmware from Samobile in download mode using ODIN?

Guess I can contact my carrier for the serial number to use in Kies.

I am currently downloading the OH1 firmware from the Sammobile site.

Suggestions?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bilgerryan:
Yep, that's pretty much all you can do at this point. Or get TWRP installed and flash a ROM. Make sure you turn off the Auto Reboot option in Odin when installing TWRP, for some reason that messes things up.
