Thanks! This worked like a dream.

Thanks again for the push, I found a ROM that worked perfectly and removed all of Sprint's crap (and replaced it w/T-Mobiles, as they say, between two evils....)

I ended up running the following Fenny's ROM....it's a T-Mobile ROM that picked up my T-Mobile SIM perfectly with data and mms. I swapped to my AT&T sim and performed a factory reset - it worked just as well. It automatically created and selected the APN during the first boot. For AT&T users, disable WIFI calling.

Thanks for the suggestion. This worked for AT&T and T-Mobile.

Instead of loading a custom recovery to load a custom rom just to have MMS working has anyone tried entering the correct MMS settings in the APN menu AND ALSO under ##3282#? The dialer code will need your SPC (which you can get from the previous page).
[Sprint Samsung Galaxy S 4 General] dwarfwarlock:
Hey first post here and I'm having the MMS problems and haven't tried to use the custom ROM yet, I would like to chime in for you.

Carrier is AIO

Obviously SPH-L720

4.4.2 and NAE

I have the MMSC/MMS settings in both the APN and the ##DATA# sections correctly setup (I have my MSL code). I have also tried multiple configs for the APNs from viewing different sites. I'm going to try the custom rom and see if it works there must be some setting somewhere that I'm missing that's causing the problem.

I can send pic messages out but can't receive any, as a side note I also don't get group messages which I don't know if anyone else has experienced.

Big problems

followed the directions. now my phone has no sound, no wifi, and will not upgrade to mf9 baseband. infact, i cant get it to do any thing.
[Sprint Samsung Galaxy S 4 General] rmc16:
I apologize for this message, but have you tried to put the battery back on?
[Sprint Samsung Galaxy S 4 General] ecs87:
OP directions are wrong. You just bricked your device because you tried to downgrade everything. Load the ENTIRE NAE firmware. Wipe data and cache. Load the MDC modem ONLY! DO NOT LOAD ANY FULL FIRMWARE UNDER NAE, YOU WILL SOFT BRICK AGAIN. At this point you should be able to unlock via the intl unlock and the service menu. Load the NAE modem ONLY after you've confirmed everything works. Win.
[Sprint Samsung Galaxy S 4 General] againareku:
Quick question, did you flash the entire fenny's rom including the modem? Via twrp?

About to do it tonight. I have spent the past week working on this phone and while i have made improvements in data speeds mms still eludes me

So I await your response anxiously, ready to be 100% done with sprint

S4 i9505 Sprint

One of my friend just come back from US with a i9505 wich is sim looked on Sprint. More accurate, we talk about L720T model. He want to use his phone on Orange gsm network. Is there any way to unlock that model for free? If not for free, he will appreciate even if he will have to pay for it.

I've read it some threads from here and there but non of them talk about L720T model. Just for L720. :eek:

Thx in advance guys. Any advice will be appreciated. :good:

I have rooted and unlocked my sprint gs4. I'm trying to activate it on a used att sim card. How were you able to get your working on att?
[Sprint Samsung Galaxy S 4 General] hindjew1:
I'm really sorry for not responding sooner. I just noticed these messages. I'm glad you're able to get it up and running. As of now, I've only used Fenny ROM. I've given the phone to a friend. She likes the stock environment. It simply works. I was able to run AT&T VVM and it took over. Please post updates on your experiments with other ROMs.

If you really want to get a stock AT&T (pure AOSP) experience, you can try to modify the ROM. Read the first post in this thread: http://xdaforums.com/showthread.php?t=2539794 - Looks like they're using Gummy ROM - Could this be the AT&T version of the Gummy ROM http://xdaforums.com/showthread.php?t=2524372 ???

I followed the instruction and now my phone can switch between Sprint network and T-Mobile's sans LTE.

I'm running CM nightly (May 25th) still running downgraded radio.

Everything is working fine except for hanging up phone call when I'm on T-Mobile's network. I can get around that by going in and out of airplane mode.

I haven't tested MMS.

Thanks everyone involved in making this possible.
[Sprint Samsung Galaxy S 4 General] ecs87:
At that point...Might it be easier to run the ENTIRE stock NAE firmware? At least everything will be working minus MMS

Noble effort... but...

Simply flashing Gummy will NOT unlock the phone. If Gummy solves the MMS problems, then you should re-title the video "MMS fix for unlocked Sprint S4" etc.
[Sprint Samsung Galaxy S 4 General] akhockeychick:
Mostly happy except for incoming call quality

Sorry if this is a repeat question that has been answered (I haven't found it in the 82 pages of posts).

I've followed all the steps, read the threads and was only able to get MMS to work via moving to a t-mobile rom but like before this switch, incoming and outgoing call quality is horrible with a few random ok calls. The other person is always garbled but they can hear me just fine. I'm fairly certain I screwed something up but am out of ideas as to what since I think I've tried most everything, including going back to full-on stock then redoing the steps. I've gone to the mobile networks menu, verified the APN, network mode, and selected the proper operator but still horrid. Any suggestions?

ROMs I've tried:

Stock Sprint ROM (no MMS so switched to t-mobile ROM)

Fenny-UVUFNB4-stock-rootedv1.3

Goldeneye version 29 and 32.1

Baseband: L720VPUFNAE

Kernel: fenny's kernal

Build: KOT49H.M919UVUFNB4
[Sprint Samsung Galaxy S 4 General] Supertacomonkeyexplosion:
Are you using t-mobile , some other mvno?
[Sprint Samsung Galaxy S 4 General] akhockeychick:
T-mobile.

*edit* Maybe I need to switch to a different ROM so the ROM build number matches the modem...? I think I've done this but I'll give it another shot and update

*edit 2* I said screw it and went back to stock NAE ROM which got my calls to be perfect (yay!) but not able to receive incoming MMS though I can send, blah blah blah. Time to see about alternative options.
[Sprint Samsung Galaxy S 4 General] akhockeychick:
Between a ROM and a hard place

Update to my previous post

Here's what I've figured out: If I want to have good call quality, I need to stay on stock Sprint ROM because even if I match the network types/preferences/etc. on a T-Mobile ROM, no bueno. If I want MMS, I need to switch to a T-Mobile ROM. I've tweaked, flashed, restored, started from scratch with a fully stock Sprint with no tweaks in the 0011 menu, followed every post that claims to have had something work for them, and everything else I can think of. I do know I can't access the MMS Protocol option to make it WAP 2.0 (not greyed out since it isn't even visible) so I tried a host of APN setting apps, changed settings in ##data#, and nope, nothing. I'm on NAE everything, if that helps. After all of these things, I have no clue as to what I should do next to find a fix :mad:

Any and all suggestions are welcome and feel free to tell me to search MMS or whatever other terms you'd like and, if it's one I haven't tried before, that's what I'll do but I'm completely out of ideas. I also promise not to take offense at implied tone or anything. I just want this &#*(#@#^ thing to work!
[Sprint Samsung Galaxy S 4 General] ecs87:
Have you tried the GoSMS app on the stock NAE build? (Sorry if this has been mentioned previously. It's been a long day)
[Sprint Samsung Galaxy S 4 General] akhockeychick:
With GoSMS, I can send mms but I don't get them. Well, I do if I send myself an mms though that's a bit pointless...

There's more to flashing the rom as in the video it says DO THIS BEFORE FLASHING ROM the rom will help it get better signal on that particular carrier!!!
[Sprint Samsung Galaxy S 4 General] akhockeychick:
I haven't tried the Tmo CM ROMs so I couldn't tell you. I'll keep an eye out, though.
[Sprint Samsung Galaxy S 4 General] ecs87:
Stupid question incoming. Have you plugged in the MMS settings for T Mobile into the MMS settings of the GoSMS app?
[Sprint Samsung Galaxy S 4 General] akhockeychick:
Not at all stupid unless my answer is just as stupid, which it's down-right idiotic: No, I hadn't but am fixing that now. Question about the settings: is it just the APN settings with MMSC as the mms.msg....etc, the proxy 216.155.165.50, and the port 80 (I've also tried 8080) OR do I also need to do the User Profile URL and User Agent? If the last two, what are those supposed to be?
[Sprint Samsung Galaxy S 4 General] ecs87:
Nope, just the regular ole APN settings. Ignore those other two. I think they're for legacy phones.
[Sprint Samsung Galaxy S 4 General] akhockeychick:
Perfect and thanks.

So I put in the APN information into the GoSMS Pro app and the only way I can get a picture from myself is to select the Big MMS option. I can send either the < 0.3 MB MMS or the BigMMS option to others. I still do not get any MMS from other people, though.

*Update*

I flashed a different TMO ROM and got everything to work. Thanks for all the help and suggestions :D
[Sprint Samsung Galaxy S 4 General] rizwan5:
mms fine

how is everyone is having problem with MMS I follow everything and I got internet and MMS working when I put the T-Mobile APN only thing is getting the 4G or 4G LTE to work on Sprint Samsung Galaxy S 4. only H or H+ and some area call quality is no good but everyone have 1 or 2 bar there so i dont really mind. im running stock Sprint ROM 4.2.2 and never went above that. any ideas on getting 4g to work
[Sprint Samsung Galaxy S 4 General] akhockeychick:
I wish I could tell you why mine wouldn't work but I honestly have no idea! I've followed the OP I don't know how many times but never got it to work until I switched over to Goldeneye Rom 32.1 (v29 didn't work, though). I also only get Edge service though the TMO coverage map says I -should- begetting H+ in my home location but when I go to Seattle (albeit rather rarely), I get H+. I'll stick with the settings I have now because everything is working, even if it isn't as fast as it could be.
[Sprint Samsung Galaxy S 4 General] rizwan5:
LTE?

i know if someone could get the LTE to work that work be great i have been using my phone for about 6 months and i had not problem but where i work i have bad connection but i thinks thats everyone there.. that person above you said he got everything to work is that mean LTE too?

[Sprint Samsung Galaxy S 4 General] waxlabo:
MMS partially works. Have you tried on another phone to send pictures to the phone? The problem is text and images can be sent out but I can only receive text but not images (while using unlocked stock). I don't think we will ever be able to get LTE on T-Mobile for this device since it doesn't have the same band that T-Mobile uses for LTE.
[Sprint Samsung Galaxy S 4 General] rimgarciag:
I also have MMS working. But I'm using T-Mobile's MVNO. First I was using sprint roms. Now I'm using a international rom. My MMS working sending/receiving on sprints and international roms. I had issues last week with MMS, but they start working again. Been using sprint s4 unlocked about 6 months ago. On LTE you are right. Only way to get it working is if a gsm provider uses band 25. Which is what sprint uses with this phone.

Question

Hi, mysoftware version is L720VPUFNAE. Will it works?
[Sprint Samsung Galaxy S 4 General] BD6131:
Domestic unlock not needed to use T-Mobile SIM abroad

It seems the domestic lock is enforced entirely by blocking access to domestic GSM towers, not by blocking any SIMs.

I tested this by using a T-Mobile USA SIM on an L720 (unlocked via autoprime's tool, nothing more) on a variety of international carriers while roaming. With this device, I could not connect to T-Mobile in the USA, but it worked fine for unlimited data roaming abroad!

For someone not interested in any hackery, it seems getting the Sprint international unlock (via OTA) and a T-Mobile prepaid SIM would be the cheapest way to use their phone abroad.

9) Press menu and back and select [2] BAND SELECTION and select WCDMA/GSM ALL for both WCDMA and GSM band preferences. I selected the ALL choice for LTE as well even though I know it isn’t supported for TMOBILE.
[Sprint Samsung Galaxy S 4 General] ecs87:
Just pick WCDMA all right off the bat. Don't touch anything else in band selection. Notice how the last thing you tap has an asterisk on it? It doesn't matter the "sequence" you do it in because your last tap is the only thing it remembers hence the asterisk.

so after following all the steps i'm now on the stock sprint 4.4.2 rom with a flashed MDC modem does anyone know of a custom rom thats compatible with this unlock method? and also if i do flash a new rom will i have to redo all the steps?
[Sprint Samsung Galaxy S 4 General] skrapmetal:
I've spent over 12 HOURS trying to get this working.... I need help please. I have successfully unlocked a L720 before but this one stumps me.

I am on 4.4.2, NAE, rooted with recovery. I downgraded my modem to MJA to do the international unlock which worked (i think), then I did the domestic unlock. I went through all the steps trying modems MDL, MF9, MJA, and MK2. No matter what I do, I have a red X over my bars. I have a straight talk SIM installed. I have put my modem back on NAE so that I have wifi, but I STILL have no signal or data. When I go into network operators and select AT&T, it hangs for a long time and then tells me 'unable to connect, try again later'. What could I be missing?

UPDATE my SIM was new and unactivated but I was under the assumption that I would at least be able to see the signal before I activate it. I was wrong. Soon as I activated it, I got a signal and data. Straight Talk sims do not display a signal before they're activated. MatroPCS SIMs will display a signal before activation. I hope that helps someone.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
As a general rule, all AT&T SIMs (including MVNOs) are that way, while all T-Mobile ones (including MVNOs) will show signal

Installed on my Sprint S4

Thanks to OP and everyone on the thread. I was able to the below steps.

Steps completed:

Used the OP steps and completed unlock on my sprint s4 (baseband downgrade, international unlock, domestic unlock)

Reverted the baseband to MF9

I did not do a full test , but when I put my tmobile sim , basic things were working.

My questions:

How can i upgrade my ROM to kitkat?

When I go to mobile networks, I see an option for LTE/GSM/WCDMA, If I select this will LTE work on tmo sim?

should i upgrade baseband, LTE modem etc to get LTE working?

I tried to get the Tmobile Google play edition, but was not sure if I get a matching modem, or will it work with MF9?

Is there any way to Tmo OTA updates after the unlock so that I dont have to flash roms everytime ?
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
1. Install custom recovery and flash from there

2. No. LTE won't work

3. Unlock should stay regardless of ROM

4. It's a Sprint phone. You won't get T-Mobile updates
