That's actually why they have WiFi calling. It's for when you're someplace that you don't have a good sprint signal but have WiFi coverage. T-Mobile is actually heavily advertising their WiFi calling now. I guess I'm pretty lucky in that I have pretty good Sprint coverage most everywhere I go. I guess it would be nice if you are in a coverage hole to be able to use WiFi for calling/texting, etc.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Dngrsone:
Hmm. I suppose so... I'm just glad my signal is better with the S4 compared to the 3G phone I had before.

WiFi calling has saved me lots of money when I had to spend hours calling back to the US from Europe while on vacation. Quality of the calls was great.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Cooljb:
That's a good point too. I didn't even think about that. So calling from europe to US didn't cost anything using WiFi calling? I'm surprised Sprint doesn't have some way to screw you over when you do that.

Can't boot, Can't boot to recovery, can boot to download mode.

Hey Guys,

My roommate tried to update his phone to lollipop and in the process managed to soft brick his phone and it will now no longer boot beyond the samsung logo. I believe he tried to flash an image from the regular sprint gs4 and not the 720t.

It will not boot to recovery at all, but it does boot to download mode just fine.

I've tried using odin to flash a stock rom but it still won't boot after completion. I tried using cf auto root to reinstall the stock recovery but it still won't boot to recovery.

Does anyone have any guidance on what I can do to get his phone functioning once again? Any help would be greatly appreciated.

Thanks!

Viaero voicemail????

I have been using my l720t happily unlocked for a few weeks now on Viaero network, besides the lack of LTE, my biggest issue is voicemail.

I do not get any notifications and the voicemail prompt in the software still dials Sprint. I cannot seem to find a setting to change that as in older phones. Is there any work arround?

Thanks again for all the help and work that made getting this phone to work for me :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Well what he most likely tried to do was odin the international s4 the USA s4 does not have stock lollipop and if he did do that yes its a brick I'm not even sure a pit reparttion will fix

Still looking like we'll get Lollipop eventually...

http://device.sprintpcs.com/Samsung/SPH-L720T-SPRINT/OB1.rdf

That translates to a new build on Feb 2015 Build one

Looks like OA4 was the first Lollipop build, so that was the 4th build published in January 2015

For those who who paid for wifi tether router. I asked the maker (Fabio) how we can continue to get updates, since the app is no longer in the play store.

Answer: It is still under the "All" list under My Apps.* It is hard to find because that list is so long. And it did let me update :)

If there is an update, the button at bottom right will say Update. If there is not an update, the button at bottom right will say Installed.

It is unclear whether we will continue to get update notifications other that this.

It's not an OS upgrade - it's still 4.4.2:

http://device.sprintpcs.com/Samsung/SPH-L720T-SPRINT/OA3.rdf

I can't believe it's been over a week though and nobody has gotten this update yet.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
I guess it depends on one's definition of os upgrade. To some folks, just because the os version number does not change, it does not mean it's not an os upgrade. Some people consider os patches and fixes to be an upgrade.

But one thing would seem certain. OA3 does not appear to be lolli pop.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Cooljb:
It also doesn't appear to exist... :( Since it doesn't seem that anybody has actually gotten this update. I've been all over google and the only mention of OA3 is right here in this thread and the sprint support page posting. The Lollipop update (OA6) for the Sprint S5 was announced a day AFTER this one was, and it's already been posted on sammobile.com. No sign of OA3 on sammobile or KIES yet.

rvilla1217, you must not have the 720T, but the 720. The 720T will not work with NAE and I once tried it by accident ;) and it never booted. NAF is for the 720T and as of yet I have not seen just the modem for zip or odin install. Later on tonight when I have time I'll pull the modem image and convert to tar for odin.

Hi folks, flashed KK sacs on 720T no baseband. Anyone can give me the NAF modem so I can try flash it over this to see if it works?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Pioneer305:
Confirmed root on sph-l720t 4.4.2 with cf-auto-root. Yes tripped Knox but don't care any more wanted root.

Was stock 4.4.2 NAF

Used the sph-l720 cf auto root

used odin3 1.85

Forgot to download all the Samsung drivers, but no worries Win7 searched and downloaded the drivers when I went into download mode and all was good.

Still hesitant on tring to flash Phil's recovery.

so

Now 4.4.2 stock w/root working well. wifi tether using Wifi Tether Router app is working using young's settings. Happy B-day to me.

The pixilation issue transfers to the device that is connected to the wifi tether.(at least it did when I tethered another S4 to mine)

Thanks to everyone working and giving feedback on this device. Helps us all.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
So all is well and this doesn't disable spark right. Just wondering if it putting in files for the L720 since that's what the root is for. I want to do this so bad. Lol just scared as ........... well you know.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] frukyyy:
According to my research, Root and recovery do not have any modem or kernels they just unlock the device giving you root and superuser access to device.

In my experience they work or fail but generally they don't brick the device.

Flashing wrong ROMs kernels modems or other mods may cause problems or brick the device.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] td030981:
Thanks frukyyy just making sure. I root the S1 with no problems and did roms. Just trying to learn this one as much as possible before I dive in. I'm going for it. Not turning my phone in for repairs lol never do. So tripping the flag doesn't bother me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Pioneer305:
Clear yes but I have not tried till today just throwing in my $.02. Dont mean to beat a dead horse.

All 3 recoveries about the same or one working better for you than the other frukyy?

And have you or anyone else keeping up with this forum having the pixel issue?

And yes td all is well just tripped the knox no loss of spark.

To have a T variant build there has to be a recovery made for our phones if not the get props will fail.

I got a quick question & not sure if this is dumb or not but I will ask anyway, I've been trying to get EclipseTW ROM from the Verizon section working on our device for personal use at the moment, so far it boots up & everything with no fc, only big issue was no data which I managed to fix a bit but replacing the APN.config file with a stock one, I managed to get data working but its a bit spotty, another issue is that WiFi hasn't been working well, I'm assuming its kernel related, I didn't wanna use Verizon kernel because I figured that can potentially cause issues for obvious, so I tried KT, but no luck & I didn't try the 4.4.x build.prop edit because for some odd reason I couldnt find the line (will look again), but anyway, to the actual question, I haven't had the best luck finding our NG5 stock kernel, like a flashable & not sure how to pull it from a stock ROM, I actually haven't even looked it up (should get to that), but um, I noticed we have the NC6 kernel on this thread, would it be a bad idea if I flashed the NC6 kernel while in NG5?, or would it not cause any major problems?

720T i9505

Hi all,

I'm finally upgrading from an LG Optimus V to a Galaxy S4. Switching providers from Virgin Mobile to FreedomPop in the process. I always found it very easy to install custom kernels/ROMs on the Optimus, but I've noticed that with so many different versions of the GS4 it's a bit tricky. Plus, the information available just isn't that well organized. This thread is an excellent resource, but honestly it's STILL difficult to glean what's needed in order for a casual user to plop a new ROM into the S4.

So, I figure I'll simply ask here... is there a Lollipop ROM with a battery-saving kernel that's fully compatible with a SPH-L720T/GT-i9505 GS4? By fully compatible I mean that it shouldn't break 4G/Spark/3G/wifi or gimp any other functionality. Working data connections are especially important to me since FreedomPop exclusively uses data instead of the normal cell network. I'm not sure about the baseband I will have; the phone is being shipped tomorrow so I won't get it for a while yet. The "S5 experience" would be nice if it adds notable functionality, but it's not a necessity if it's solely visual fluff.

A link to a device-specific n00b friendly guide for installing would be great if there is one since I'm a bit rusty. I haven't messed with ROMs since around this time 2013 as that's the point when the Optimus V's processor simply wasn't keeping up with the software well enough for my liking.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
You can't lump those (SPH-L720T/GT-i9505) two different models together. Everything that works for the 720T (Sprint) will not work for the i9505 (which I believe is Verizon or AT&T). There are considerable differences. Some mods may work on both but many will not.

Someone correct me if I'm wrong.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] grabb0r:
They are just indicators of different aspects of the same phone. The 720T applies to the fact that it's the triband capable version, the i9505 refers to it having the Snapdragon 600 chipset as opposed to the Exynos 5 Octa chipset (i9500). This is not a matter of different phones being lumped together.

And thanks... your post makes me feel a little less n00b :)
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
You're welcome and I must disagree. Yes, both phones are Galaxy S4s and some mods may work on both, but there are significant differences as well. The phones are different. I owned a AT&T GS4 for a brief time. Not only was the hardware not triband but the methods and mods used to modify the phone were very different.

Each carrier does things differently with their phones, and each carrier can have more than one model GS4 as well.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] grabb0r:
Guy, you can disagree all you want with anything you want but this isn't a matter of opinion any more than the existence of gravity is. What I'm getting is a triband Galaxy S 4 on Sprint service with a Snapdragon 600 processor. The phone model is SPH-L720T, and the processor identifier is GT-i9505. I don't think you even understand what I'm saying here.

I'm just trying to find out what ROMs are going to work on this phone without compromising functionality. Lollipop is preferred. Don't need these kinds of derails.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
the i9505 is international s4 strictly gsm our phones are cdma/gsm we are closer to the vzw s4 than any other the I9505 is a Qualcomm chip yes just like ours

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] grabb0r:
I don't understand what you're trying to say. I am asking a VERY simple and straightforward question: What ROMs/kernels are fully compatible with a SPH-L720T which has the Snapdragon 600 chipset? I don't mean to sound like a jerk here, but... if you're not answering this question you're not helping me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Any jfltespr lollipop and any jflte KitKat I believe this has been mentioned here before. I'm just trying to tell you that they are TWO different phones you can flash the i9505 roms all you want (not telling you to do that) but that's up to you. And yes I have the same spark Sph-l720T and have been flashing this phone since Feb last year. If you search before posting you would have found the information you where looking for.

---------- Post added at 09:34 PM ---------- Previous post was at 08:56 PM ----------

If you want or need help with this phone hit me up on PM or hangouts. I will help you with root recovery and flashing a rom I don't want to come off as a rude person. But I have a lot of experience with the Spark S4
