There seems to be some confusion on the matter here in the forums.
Can I sim unlock my Sprint Galaxy S4 to use ATT/TMobile sims?
Yes
Can I do it using a Lollipop Rom?
Yes
Can I do it once I flash a KNOX bootloader?
Yes
Can I do it on OD2?
I don't think so, but maybe... The best bet is to use NG2 and then experiment from there...
Can I do it without reading/paying attention/following directions?
No.. but if you made it here, you're doing OK so far...
First off, there are 2 kinds of SIM unlock for the SPH-L720. International unlock, and domestic unlock. We will cover both.
To unlock for international carriers SIMs, you have a couple of options.
a. Have sprint unlock it for you
b. Do it yourself.
I prefer b, almost always.
Lets start off with what you'll need:
Drivers for the phone, I'm too lazy to find those, but if you can't, you are way out of your depth here.
SSU.apk from here.
An NG2 Stock Rom (modem and ROM) here is an Odin tar that i used when I did it.
Odin from the same post that tar came from... (here)
TWRP recovery in tar format from here (i used 2.8.4.0, but I don't think that matters)
adb ( i use this minimal adb installer but any adb install will work.)
THIS WILL PROBABLY WIPE ALL YOUR DATA.
Put your phone in Download mode (Power + Vol Down)
Open Odin
Click the PDA button, choose the tar.md5 file you're flashing. (the stock ROM from earlier)
Uncheck Auto Reboot
Plug in a decent USB cable, from the phone to the PC
Hit start
It will take a few minutes, no worries unless you get an error.
When it is done, Hold Power + Vol Down until the phone reboots into download mode again
Click PDA in Odin and load the TWRP tar you downloaded earlier.
Hit start. This will take significantly less time.
When it is finished, Hold Power + Vol Up to reboot into recovery.
When TWRP is fully loaded, click reboot then reboot system.
It will tell you that the ROM is not rooted, and ask if you want to do that. (if you used the tar from above) and of course we want to, so let it.
Let the phone fully boot up.
Goto Settings, More, About Phone.
Find the line that says Build Number, click that line a bunch of times until it says "You are now a developer".
Now hit back, and goto Developer Settings.
Find Debugging mode and enable it.
Using adb
Code:
adb devices
that will respond with whether it finds your device or not.
Code:
adb install /path/to/SSU.apk
that will install SSU.apk from earlier..
You'll want to have the screen of your phone on for this part because you will need to approve your PC to connect.
Goto your app drawer, and run SSU
Click the Unlock button
Now your phone is SIM unlocked for international carriers... But what if you want domestic carriers too?
Unlocking for Domestic Carriers
First things first, you have to do the International Unlock explained above (you didnt think you were gonna get out of that did you?)
After that, load ADB back up
Code:
adb shell
Code:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
That will pop up a menu on your phone
Click (UMTS) then (DEBUG SCREEN) then (PHONE CONTROL) then (NETWORK CONTROL) then (GCF) then the top option.
Now reboot.
You are now unlocked Internationally and Domestically. Goto your mobile network settings and put your apn settings in (if they arent already there off the sim) and you should have data too.
From here you have a couple of choices.
a. Stay on NG2
b. Goto another ROM (i usually just flash CM at this point, YMMV)
c. experiment yourself and try to use OD2 (I've heard flashing the OD2 modem relocks it, didnt try because I didn't want OD2)
If you stay on NG2 then I suggest this apk to Stop the Sprint Hands Free Activation from nagging the **** out of you..
NOTE: as of tonight, any CM12.1 nightly after 6/23 causes a No Sim card error. This has nothing to do with the unlock, its just messed up, so until its fixed use the 6/23 nightly.
Hopefully that answers some of the questions I keep getting in PMs and what not.. If you have any question, feel free to ask.
I might not answer them, because I rarely frequent the forums anymore, but lots of people here can probably answer the questions you have.
Thanks to @autoprime he's the one that found the original unlock for this phone, and tons of others.
Thanks to @random45 for posting the ROM i used
Thanks to @shimp208 for posting (making?) the minimal adb install that i use
Thanks to @Sloosh for making the Hands free activation disabler apk

Thanks to cyanogen and Team CyanogenMOD for all they do..
Thanks to @imaxuout for keeping this topic alive in a few threads
Thanks to @AndroidKing for a similar thread.
Thanks to nicotheandroidguy also.
And anyone else I forgot (I'm sure I did)
I would probably recommend removing all references to rooting since it's not necessary. Some may only want to unlock, not root.
Substitute the dialer code for the terminal command when it comes to launching the service menu.
And putting the apk on the phone's storage and installing it with a file explorer is probably easier than adb install, for most people.

I just documented what I did. there is no one way to do it. you are more than welcome to document them in your post if you want.
I'm going to try this today and will report back. I switched to tmobile and got the s6 edge and since my sprint contract was up I was able to keep my device. Now I want to get it to my mom who has a beat down metro pcs device. In theory since metro is tmobile it should work right?

If metropcs uses sim cards, and the Bands that the GS4 has, then yes it should work. You'll obviously need APN settings for data.
So this method you need to be on KitKat in order for Suu to work. I also can't get a hold of galaxytools as the developer wants you to buy it now.
Also any ideas how to do the domestic unlock without adb?
Sent from my SPH-L720 using Tapatalk
I don't use galaxy tools, and if you aren't on kit Kat yet, you can revert the modem and use the original unlock posted by autoprime.. Or you could just flash the rom I linked too, which is lollipop, not the newest but works fine.
And as far as adb, you can just use a terminal app.. Except for installing ssu.apk, but you could just push that to your phone and install it with a file manager
I followed the above steps and still can't get it to work. Im back on kitkat and unlocked the sim. Did the terminal command and followed those steps. rebooted and under About Phone> Status it still says sprint and shows my old phone number that was tied to my sprint account. Am i missing something? I went to settings and changed to gsm/utms and tried that but nothing.
Did you put a sim card in?
Yes it was a metro pcs sim. I spent a couple hours tinkering with different steps from older threads and still could not figure it out.
Metro is unique in that you can't switch phones just by popping a SIM in.
You have to contact them and have them register the new IMEI to the phone number

How are Data speeds?
This is great thank you for posting this detailed one. If i can't figure out how to get my phone working right I'll flash stock firmware and start OP's process. Can you tell me what data speeds are you getting? I've got mine unlocked and working by changing my modem and using s4 flasher among changing other settings. It's a Sprint S4 L720 going to Tmobile. I'm only getting Edge speeds of .08 mbps and the voice is sometimes garbled. I'm not sure how I can get it unlocked and working well with everything working and getting the HSPA+ speeds. I live in a 4gLTE area so I should get at least 3g speed according to tmobile's coverage map using 72703 zip code. Trying to figure this out if anyone has suggestions on how to get out of EDGE speeds, the 2G EDGE capabilities are appalling. I haven't flashed any custom ROMS btw.

I only used it on att, but if your speeds are low then TMobile in your area probably operates on a frequency the s4 doesn't use.. Or your apn is wrong, idk which.

1. Make sure modem version matches software version
2. Make sure network mode is set to WCMDA preferred or GSM/UMTS.
3. Check Settings->About phone->Network to make sure you're actually on EDGE.
You could live in an area that T-Mo hasn't refarmed to 1900 yet. If that's the case, they're running HSPA on 1700 there, and the phone doesn't have that frequency. So that would explain only being able to get EDGE

Thought I would share based on my experiences on trying to get this phone to work on t-mobile. It works on ATT 3g/T-mobile Edge, but still a pretty cool phone to have.
Also another note, this is a mod that will only go through on Windows. You will need ROOT EXPLORER app for this method to work.
1 - Make sure you are on the stock XT862 ROM, if you aren't flash it via this method found here: http://rootzwiki.com/topic/4370-sbf-droid-3-fastboot-files-55959-and-56890/
2 - Make sure your phone is rooted, if not download the following and follow the steps found here: http://www.psouza4.com/droid3/
3 - Unlock the phone. This can be accomplished by purchasing the unlock code, and later entering the code upon insertion of a sim card. (T-mobile ATT sim cards will work, but you will get an error saying UNLOCK FAILED, this is NORMAL do not freak out)
4 - Download the following files and unzip it to your desktop: http://www.mediafire.com/?y1wjw775v8itsx3
5 - Click Start and open cmd.
6 - Type in the following in cmd:
'cd desktop'
'cd fastboot'
'moto-fastboot flash radio radio.img'
ONCE it flashes, then enter:
'moto-fastboot reboot'
7 - Use root explorer to push the build.prop into the system folder
8 - Reboot, select GSM/UMTS in Network Settings.
AND BAM now it works. If there is any confusion please let me know.
Nice! Is that the XT883 radio you're flashing or a real unlocked (and signed) XT862 radio?
Also - change
Code:
ro.mot.phonemode.vzwglobalphone=1
to
Code:
ro.mot.phonemode.vzwglobalphone=0
in build.prop to get normal reading on signal strength indicator.
You can also change
Code:
ro.telephony.default_network=7
to
Code:
ro.telephony.default_network=3
so phone starts automatically in GSM/UMTS mode after hard reset.
Can anyone confirm that it's running on AT&T with 3G/4G?

Nice Guide!
I've read some people have had trouble unlocking the D3....and apparently it could be due to it being used on the Verizon network who then alter the unlock code via some update.
Anyone know if there is any truth in this? (I'm awaiting the delivery of a used D3 so would be handy to know).

Even after the update, if you restore it to the first link and then follow the steps, you will be fine. It can still be unlocked.
Awesome! I am about to try this on my friend's droid 3. Are there issues with the market (as some have mentioned in a previous thread)?
---------- Post added at 12:10 PM ---------- Previous post was at 12:00 PM ----------
I am stuck on <waiting for device> in the command prompt after telling it to flash the radio. What sort of USB connection should I be selecting?
EDIT: I'm an idiot.... I figured it out!
Is anyone else who is using this method on AT&T experiencing super slow data speeds? I have tried the sim card in an at&t branded phone and it seems to work ok. On the Droid 3, I am getting a ping of 2500~ ms, and speeds in the 15-60kbps range.
I can't seem to add an APN and connect to the 3G network. Does anyone else have this issue? I am using a Bell SIM at the moment
Follow all the steps, no luck here
When I put the unlock code, phone shows for a sec "requesting unlock" and goes back to a subsidy lock message with a discard dialog box.
After that, I followed all other steps, and still enter unlock code appears
Any ideas?
I dont have an att sim card, Im just using foreign sim cards cause Im outside US.

You can always call the carrier and make sure they are allowing your phone to connect. I'm not sure if this is the problem, but I read about another AT&T branded 4G phone (the D3 will never get 4G) getting only edge because the carrier thought it was foreign, and they just called in and gave the IMEI number to get access.
The customer service rep may not understand your problem, but just tell them the truth that you want to use your compatible device on your valid account and they should redirect you to someone who can help.
I can verify this works on T-Mobile and AT&T since I've tested it on both. Didn't test 3g on AT&T though cuz I didn't think about it lol. I know it allows the connection to umts in the settings though.
The OP poster helped me get it working on my phone just make sure you follow the directions closely and it's pretty simple. If your unlock codes aren't working because you got them off the internet, you may need to have the phone put on Verizon temporarily to get them to give you a code. Just ask a friend with a valid account to help you out.
Good luck to everyone, this is a great hack that definitely saves some money while letting us use this cool phone. I will have to edit my build.prop as mentioned above to fix the reboot network loss problem, thanks for that as well!
Droid 3 with stock xt862 ROM working on T-Mobile via xt883 radio.img & custom build.prop
If verizon changed the codes while phones are connected to his network, changes could only be stored on a new bootloader.
There is no other unwritable part on the phone.
Wonder if the original poster used an ebay code or a verizon one...
Nice job! Pretty amazing what can be done with fastboot and signed radio images!
Custom ROM
What will happen if somebody follows this procedure and unlock the phone for AT&T but afterwards flash another rom? Will the radio still be unlocked for AT&T?

As long as that ROM you're flashing does not have radio image in it, you should be fine. If you meant sim lock - once unlocked, it will remain unlocked forever.

Now, I haven't tried flashing another ROM since flashing the xt883 radio.img, because I really don't mind the stock ROM with some build.prop tweaks and the help of Zeam Launcher. I would assume that any ROM you flash would cause the build.prop and radio.img to be replaced with new ones, made specifically for that ROM. You should probably consult with the developer of the ROM you want to use, and ask them if the build.prop changes specific to this process will have issues with their ROM. The xt883 radio.img shouldn't have any conflicts, but I believe it will still require the custom build.prop file which is found in the OP, or at a minimum the specific changes which allow this tweak to work.

This is only working for ATT and StraightTalk - ATT Sim. If you have another carrier you will have to do the procedure yourself below.

Goes in /data/data/com.android.providers.telephony/databases

that didnt work for me, stock rom but linaro v3 kernel.
Well. It seems I have hotspot enabled on my plan but not getting charged for it. That's why this mod works for me but jot anyone else.
So the Att version is broken

Don't know. Typing this now on my A500 using First hotspot with Straight Talk/ATT SIM.
Flashed the zip and it didn't work for StraightTalk. Not familiar with the installer but seems to be a script bug when checking for ATT / ST selection.
Manually copied the ST db and it didn't work, got the error "dial 611 or go to myatt.com to activate hotspot"
And it changed my ST APN settings.
I manually updated the db with SQLlite and got it to work with StraightTalk.
The ST db file in the zip uses the old APN setings, I was provisioned with the new settings.
See this thread for details on the ST APN settings.
New Straight Talk APN

So… what's the procedure?
Analyzing your files in SQLite I see you changed tables 2 and 12, but I can't seem to figure out the logic behind it. My experiments don't get me too far.

No, nothing in build.prop. What ROM are you running? What SIM are you trying to use? I was using AT&T via ST, is your T-Mobile via ST?
If ST, was there a recent change in the APN settings? I have read that there were some updated AT&T ST APN settings, but they do not work as well as the old ones, at least in some markets. I tried them to see if there was an improvement and actually lost all data, so reverted.
Stock 1.08.
I'm outside the US at the moment, so my carrier couldn't be further from AT&T, T-Mobile or any of their MVNO's. But the APN settings are correct: tethering works with factory unlocked phones.

You need to be rooted and s-off for changes to stick in system files. Good luck.
Ran into a tethering issue after addition of a third, but not selected APN. Tethering showed connected but there was no Internet connection. I tried setting up the new ST settings to see if my SIM could access LTE. It could not. I then simply re-selected my original APN. All seemed to work OK, except the tethered wifi device could not see the internet. The additional setting changed the order in the telephony DB list. Went back to just the two APNs and all is again fine.
I cannot get telephony.db to stick on my friend's First for some reason. No hash match after reboot every time. Tried zip installer and ADB push, in TWRP and in OS. 1.08...1 S-off and rooted. Also tried deleting telephony.db-journal first like the installer script does. So strange because I've done it with my phone. Note that I had downgraded from 1.08...4 to do this.
Is JmzJBSenseMyst_v3 new? That's what im running. I tried this on MEDUSA as well with no go.
It basically messes the phone up completely un-useable since I'm on Straight talk att blue sim and on apn - tfdata.
So how do you get tethering on this phone with apn - tfdata for att straight talk blue sim for 4g lte... ?
I can't get MMS to work at all... it won't download says download error even after putting the mms proxy and port 80 etc..

[HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk
Streamlined Guide for Domestic T-Mobile GSM Unlock for SPH-L720
Credit for all of this goes to @autoprime and @nicotheandroidguy
A few notes: I used Windows 7 for the odin flashes , my phone is a SPH-L720 and it is not active on the Sprint network, also the sim card from t-mobile was inactive (brand new from t-mobile store.) and it has a bad esn. I am located in the Phoenix az market so I'm able to take advantage of the 1900mhz band that tmobile has here.
I'm unsure of how this will work with mnvos or other primary carriers and frankly I don't care at the moment, this is my primary phone. Update: confirmed hspa+ for tmobile, metroPCS, straight talk and AT&T.
I HAD MY NEW UNACTIVATED TMOBILE SIM CARD IN THIS ENTIRE TIME
1) First I reverted my rom to a stock MF9 rooted touchwiz rom, instructions and one click odin here:http://forum.xda-developers.com/showthread.php?t=2486134 I’m trying not to straight copy and paste someone else’s work so take a look at that post if you need a clean start. If you are coming from non stock you will need to boot into stock recovery and wipe data/cache before you get started. (I also later used SAC’s rom after a failed attempt at an AOKP fix and it worked as well ) you can switch to any ROM later and the unlock will stick.
2)I rebooted the phone and followed the instructions listed here in post #1 http://forum.xda-developers.com/showthread.php?t=2415587
3) I went to the dialer and typed *#0011# which brought me to the "service mode" Menu.
IF YOU HAVE TROUBLE GETTING THE HIDDEN MENU TO OPEN DO NOT FEAR! I had a ton of trouble at first. In some builds you need to activate an option by adding a line to your build.prop or changing the no flag in efs/hiddenmenu to ON. Google it, there is a ton of help out there.
4) Press the left menu softbutton (the menu button that lights up and vibrates when you touch it) then press the either the button “select” or “Key Input” and type the number 1 or 2 into the box, if nothing happens press menu and select the “back “ button then repeat. This app is sort of like a tin can radio, you can kind of tell that it’s working, but it doesn’t work well.
Depending on if you pressed 1 or 2 in the dialogue box it will take you into either an UMTS or CDMA menu. If you are in the umts menu, press the menu button and select back, this should then proceed to the next step.
5) Select CDMA, then 1.COMMON, press next page twice until you reach page three of COMMON and select 8.PREF MODE SET and select GSM_WCDMA_ONLY
6) Press menu and back until you are at the main menu and select [1]UMTS, then select [1]DEBUG SCREEN, then select [6]PHONE CONTROL, select [2]FAKE SECURITY CONTROL and make sure it is set to ON
7)Press menu and back and select [3] NAS CONTROL. We are going to check a few different settings in this menu so remember how to get here cause I don’t want to repeat myself.
[1] CIPHERING CONTROL = OFF
[2] INTEGRITY CONTROL =ON
[3] SIM CLASS CONTROL = UMTS
[4] REVISION CONTROL = DO NOT TOUCH
[5] RRC(HSPA) CONTROL = DO NOT TOUCH
[6] DUALMODE IMPROVEMENT CONTROL= DO NOT TOUCH
[7] NAS AVOID SECURITY CONTROL= OFF, 0
[8] BIP BLOCK = 1
8) Press menu and back twice, you should be on the PHONE CONTROL menu. Select [7] NETWORK CONTROL, select [1] GFC and make sure that it is set to [1]GSM/(E)GPRS/WCDMA REL8 .
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.
10) Under the NETWORK CONTROL menu we just came from select [4] AQUISITION ORDER and change it to [3]UMTS_GSM
11) Press menu and back until you are in the PHONE CONTROL menu and select [5] SIMULATION , press the [2] SW WATCHDOG button 6(six) times and then the [3] HW WATCHDOG 6(six) times. Nothing will happen at all to let you know if you have done this correcctly but as soon as you finish the sixth press on HW WATCHDOG reboot the phone manually:manually:manually IMMEDIATELY . I’m not sure what this does or why this works but @nicotheandroidguy seems to have divined that this is the vital part of the process.
YOUR PHONE STILL WILL NOT HAVE DATA OR VOICE WHEN YOU REBOOT FROM THE WATCHDOG TAPS DO NOT PANIC!!!!!!!!!!! (hopefullly you have your towel with you)
12) WIFI that sonofa up and search for apn settings shortcut and build.prop editor in the Play Store.
Go into the build.prop editor and add the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
REBOOT PHONE MANUALLY now.
Now Install and create a shortcut on the home screen and select to open. Press the menu soft key and select add apn.
Use:
Name: T-Mobile
APN: epc.tmobile.com or fast.t-mobile.com (for LTE devices)
Proxy:
Port:
Username:
Password:
Server:
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS proxy:
MMS port:
MMS protocol: WAP 2.0
MCC: 310
MNC: 260
Authentication type:
APN type: default,supl,admin,dun,mms
13) Go into your android settings, select wireless networks, you should see the network mode set as wcdma only do not change this, we set this in the Service Mode Menu , Check that your roaming settings are set to for roaming data/ international data etc.also make sure that there are no roaming guards left on. (roaming guards will only allow you to uncheck GSM and GSM data under international roaming.)
14) reboot
15) profit
At this point I had full access to the TMOBILE UMTS/HSPA+ network and voice/text/mms were working.
At this point you may change roms, be careful not to update past mf9 as you may be unable to downgrade to mdc. YOU MUST DOWNGRADE TO MDC MODEM FOR THIS TO WORK.
If you use a non touchwiz rom you can still access the tellinfo menu by pressing *#*#4636#*#* and selecting WCDMA only and manually adding the apn.
GOOD LUCK! let me know what needs changed in the guide as well.
If you have questions it's useful to know your Baseband /kernel/ rom.
Nice. Will it work with t-mobile in Los Angeles?

Most excellent! If you fiddle with acquisition order and make it gsm_umts it might identify your network type correctly.
My 1st newbie post:
Thanks for OP's excellent post!:good:
I have a Sprint Galaxy S4 is with stock MF9 (not unlocked).
I have spent days reading about how to get a rooted/unlocked MJA S4. But still could not find answer to the questions:
1. Will this also unlock international sim?
I guess yes, as domestic is harder to unlock. But want to hear the confirmation.
2. You mentioned you used MF9 rooted.
If I unlock it, then update to MJA, will that void the unlock?
3. Does this unlock works with MJA? If it works, do I need to unlock MJA first?
4. If I want a rooted & unlocked S4 with stock MJA, what is the simplest way and the correct order to achieve this goal?
Can I update to MJA, then root, then unlock?
Or do I need to root the MF9, then unlock, then update to MJA, then root?
If I update to MJA first, I can't go back to MF9, correct?
Thank you very much!

Ok
1)i am unsure of whether mja can be unlocked internationally or domestic . If you read the first direction it actually instructs you to downgrade to mdc modem. I'm pretty sure the reason has to do with the options available to you in the hidden menu.
2)i used mf9 rooted as a starting point to downgrade to mdc to perform the international unlock. Autoprime said in the thread that upgrading to mf9 would keep the u lock however I haven't successfully upgraded to mf9 and kept the domestic unlock. I'm going to try to get it to work today but not with mja until there is a reliable downgrade option.
3)i have no idea. I wouldn't suggest trying until there is a reliable downgrade option.
4)i would really slow down and read the international unlock guide from @autoprime I think it will answer a lot of your questions. Like I said I would wait to upgrade to mja if you want a for sure domestic Sim unlockunlock.
Thank you very much, imbmiller.
I will just wait patiently for the MJA solutions before upgrading to MJA/root/unlock.

So would this also work for AT&T sim? has anyone else tried? Btw, was thinking of updating to 4.3 and MJA but i guess i will have to hold off on that if i want sim unlock international or domestic? I am on MF9 with sim international unlock right now. Would I have to go down to MDC to get this to work?
Also, if you want to go back to sprint again, how would you do it?

Hi thanks so much for putting this together all in one place!
Hi I'm on MF9, rooted, locked.
So really the two major steps are:
1. Do int'l unlock first (autoprime)
2. Then do domestic unlock
My question - after you get both unlocks working and say you have your phone working on tmobile, what do you need to do to get it working on Sprint... rather, is the phone operatable on both Sprint and Tmobile? Or do you have to do some tinkering to get it back to working on Sprint again. I'd like to have the flexibility of popping SIMs in and out and switching carriers at will, Sprint included (b/c I don't want to cancel Sprint just yet...eventually, but not immediately). Thanks!

Another question
When you're tinkering with swapping out modems and APN settings, does doing a nandroid backup prior help so when you have an "oh sh!t" moment, you can just do a full restore...? Or is what's backed up in nandroid outside (excludes) these changes? Thanks.

OK the answer to the first question is to put your sprint sim card back in then put your phone back in to lte/cdma auto through the tell info app through Google play device info then change it in to lte/cdma auto.
Answer to the second question is that the nandroid might help you in a oh sh!t moment but the modem and settings for the unlock stay after a factory rest but a other update could kill it. A stock Odin flash and dailing ##72786# could also kill both unlocks.

Sorry I had to edit my post. It did work. There are two different GSM SIMs the one with the dot seemed to work. I Got Edge, 3G, and H+. It is awesome. I also still have 3G with Sprint with the SIM in. I got two phones in one. Thanks.
So I've been on T-Mobile for the last 24 hours but my HSPA+ signal is weak and slow (under 1mb), while my co-worker on T-Mobile (and a T-Mobile phone) has full HSPA+ signal and speed (5-9mb).
Any thoughts on what could be the cause?
I'm running CM11 on MDC. I'll try some other combinations tonight to see if things change.
Okay, I just got through doing this myself and it seemed that nowhere was this all said at once, or at all. So I thought I'd whip up a quick tutorial concerning how to Domestic Unlock the Samsung Galaxy S4 on any of the newer bootloaders/firmwares/modems. (Knox-enabled)
I did this on both a 4.4.1 galaxy and a 4.3 galaxy- one one NAE and one on MK2
First, for anything to work your modem must be an older one, like version MDL. Download the file SPH-L720_MDC_Modem.exe which is a one-click
Odin .exe that will flash ONLY your modem to MDL.
Steps- put into download mode by taking the battery out and putting it back in. Hold the volume down button, the home buttone and then press the power button. When it vibrates, let go. Press volume up.
Run the SPH-L720_MDC_Modem.exe odin one-click installer.
Connect the usb to computer from phone
when com[24] or whatever shows up, press start.
Now, for the domestic lock to work you first need to do the international unlock @ http://forum.xda-developers.com/showthread.php?t=2415587
It's real easy and explained well at the link above, but I'll run through it quickly anyways.
Download the s4unlocker installer from the post linked above.
Put your phone into diag mode by dialing ##3424#. Press Qualcom button and select the bottom selection.
connect (if it wasn't already) usb from phone to PC
You already installed the proper samsung drivers, right? If not, you'd better do that now.
Okay, now run the s4unlocker and press the scan and unlock button, then wait for the phone to reboot.
Now for the Domestic Unlock part.
Follow the directions at http://forum.xda-developers.com/showthread.php?t=2530610
I'll run through it real quick, too because there were a few things I wanted to mention.
dial *#0011# (or #*0011#, I can't remember)
when it comes up "No service", press the menu key on the bottom left of your phone. This brings up a menu (wow!), on which you should press "back"
Now press the menu key again and in the menu select "key input" A box will open up asking for you to type in something- enter a "1" and then press the enter key BEFORE hitting the OK button. Mine would not work unless I did this.
Now wait, sometimes it takes a good couple of seconds to give you the menu. Follow the rest of the directions from the above link, setting all the settings to what is stated. EXCEPT where he says to set all the preferences to WCDMA ALL, GSM ALL and LTE ALL. When I selected one, however, an asterisk appeared after my selection leading me to believe that you can only select one of these and so I set mine to GSM ALL and left the others alone. This worked for me, so I thought I'd mention it.
Now that you've manually rebooted after following the directions, you still have to edit your build prop to allow you to edit the apn settings. To edit your build.prop you must be rooted so root with CF auto-root http://autoroot.chainfire.eu/ download the proper one for the galaxy s4.
It's just an odin flash, so enter download mode
load up odin 3.x
hit the pda button and select the cf auto root tar
hit start.
After rooting I found that one time I had to do some of the service mode settings again and one time I did not, so I mention it here even though I think I had to because of some other error I had made at the time.
Go to play store and download build.prop editor and APN settings Shortcut
Load the build.prop editor and add these two lines to the end of the file
ril.sales_code=LOL
ro.csc.sales_code=LOL
Now reboot manually
add the apn settings widgit to the main screen and open it
click on menu and add an apn
Enter the apn settings for your carrier here. They're all different,(the carriers) but you can find them(the apn settings) easily with google, since they (carriers) all post their apn settings on their webpages.
Don't forget to save the apn settings.
Now select it.
Now reboot, since it couldn't hurt, right?
If you've done everything right you should now have an domestic and international unlocked Sprint galaxy s4. Enjoy.
I suppose you could now reflash the new modem back onto the phone, but I don't have firsthand knowledge whether this works or not- I've only read that others have said that it works. Remember, ONLY FLASH THE MODEM, the rest isn't necessary and will probably knox you all up
All I did was list these things- credit goes to all those who were linked in the above post. Thanks for all you do.
On stock 4.3 and higher you can go into settings and change your APN, so there's no reason to root and mess around with build.prop editor.
Every time i try this i cant get my wifi back up when i flash back to the nae modem. If i could get pass that then I'll definetly be do that.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.
You can downgrade modem, but can not downgrade bootloader (aboot)

I completed both the international & domestic unlock. I believe I was successful in each. I have a T-Mo sim card inserted but am not getting a mobile data connection. I do have 2 bars of service though. So I have gotten past the red X on the bars.
I am on 4.4.2 with the MDC modem. I did not do the build.prop stuff, instead opted to just access the APN's from the default menu.
A few things in my menu were different than the OP (probably because of 4.4) such as:
I dont have any roaming menu options
I dont have WCDMA.. just CDMA and LTE/CDMA. I currently have it set to LTE/CDMA
In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

You didn't unlock it. If you were on NAE modem while unlocking then you failed miserably because you're not able to get into the most important part of the unlock...The service menu. If you did indeed downgrade the modem then you're going to need to follow the domestic unlock guide again. If it's showing CDMA/LTE you didn't do it right. It should show WCDMA only and WCDMA only isn't an option you can just select. It gets put there by the service menu.

I said I wasn't on NAE, I am on MDC. I did get into the service menu. I did everything in the process without issues. My service menu did NOT have a WCDMA only option. It had LTE/WCDMA and that's what i chose. I just went to the t-mobile store and they verified my APN settings were correct. I am unsure of what to do at this point other than just start all over and do it again.
Anyone else?

I apologize. Long work day. Follow the guide. When it comes to where it says select LTE, GSM, and WCDMA all, ONLY select WCDMA all. At no point should you see your Sprint phone number in about phone. Also you should see IMEISV in about phone as well if you've successfully unlocked it. It'll help if you posted the steps you've gone through. Otherwise were just shooting in the dark.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.

Imeisv visible, definitely unlocked as i can make calls texts and use edge data on redpocket mobile (att mvno)
But in phone number I still see my sprint number and I can't get hspa (picking the wcdma all gives me red x no bars, picking gsm all gives me full bars and edge data)

From the S5 thread and now here we meet again in a revisit in time. Since I know you own and understand the L720 more than I do, could you please explain to me if this will work on a 4.4.2 NAE rom? I picked up an L720 (bad esn) for $100 and its in pretty great shape. Now I'm looking to unlock it but my experience with Samsung devices are very mild. It came on CM10.2 (4.3.1) and ive slowly caught up with things. So i understand that sadly there is no such thing as downgrading from KK to JB, I was trying to get it stock on JB with no cigar. Elsewhere I found out that you must flash something identical or above. So im planning on flashing an NAE 4.4.2 stock rom (custom recovery flashable) I found in order to attempt to unlock it cause I can't seem to find a 4.4.1 as mentioned in the OP. I flashed the MDC modem and it stuck, so with little knowledge I am assuming that it will stick once I flash this new rom? Correct me if I am going down the wrong path...
EDIT: Great nobody ever mentioned anywhere that the software used on the international unlock is for 64bit only...

The software works on 32 bit too. Actually you can even perform the international unlock WITHOUT the tool if you know how to use QPST or DFS. Anyway...
Flash full NAE. Flash MDC modem. International unlock. Domestic unlock. Win.

Must be an issue with my PC, nothing new...
And I know a thing or two about QPST. I still have it on my computer from a few days ago from when I was fixing a horribly corrupted IMEI on a G2 a friend of mine bought. I'm assuming I have to use a NAE stock tar with ODIN, because I tried a ROM of it and it lags and stays on black screens for seconds and WiFi doesn't work im sure because of the fact that the modem is older than the rom. Let's see if that works cause ive been trying to flash back to any stock ROM since I got this thing yesterday.
(Almost there...)
NEVER MIND. Got the international part working perfectly by using the Windows Vista partition on my PC. Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

Read the specifics. You cannot downgrade boot loaders but you CAN downgrade modems.
Unlock just requires MDC or MDL modem.

Yeah I remember that part but from what I was understanding, that's for the international. Domestic requires messing with some files and done. I already got the international part by tossing CM10.2 along with the MDC modem because stock Touch wiz would cause lag and reboots and non working wifi I'm assuming because of the mismatched combo. I DO know that obviously we need a TW rom in order to unlock domestic.
EDIT: I finally got the hint and got it to work. But I only get Edge instead of 3G. Does anyone know where I may be able to find that T-Mobile rom made for us? When I Google it I end up on the T-Mobile side.

I downgraded from latest bootloader on 4.4.2 or was it 4.4.4? Down to 4.3 which is the absolute best ROM version for service mode menu. It got me into service mode menu on first try by selecting menu back and input of 1. What I did was first install cf autoroot to root then cwm and used cwm to flash the 4.3 stock deodexed, I only used Odin for flashing modem. Odin gave me an error when flashing modem and phone got stuck in kies mode but i got it to get unstuck by just flashing cf auto root again to make the kies mode error thingy think odin flash has went well. Turns out MDC modem flashed despite odin error.
Anyways. While on 4.3 and MDC modem I noticed no WiFi but I had sound. I followed the international and domestic unlock instructions and WiFi was still broke when I got back to 4.4.2 but I had unlock and sim card working and got bars. I am on aosp 4.4.4 now and the nae modem I finally flashed works well with this ROM but soon I gotta go to touchwhiz 4.4.4. If I go to 4.4.4 touch whiz WiFi and all else will work fine just as they do on slim aosp . 4.4.2 touchwhiz is still not giving me wifi on NAE modem. Update NAE 4.4.2 stock deodexed rooted rom i got from xda android thread did the trick and all works well now. All is perfectly working after i flashed it in cwm.
For aosp lovers. aosp requires additional things to do so aosp dialer can make and receive calls fine. I can call but there are issues until I follow another guide on xda that resolves those issues on aosp ROMs using sprint s4.

If you see system slow, no wifi, no audio and lockscreen being nearly impossible to unlock, its due to you being on a higher ROM than the modem was meant for.
I spent the last few days on my phone learning all about flashing Cyanogenmod, the differences between SPH-L720/SPH-L720T and wanted to put everything I learned about my experience in one thread as it is pulled from countless sites.
I have the Boost Mobile Galaxy S4 SPH-L720T, rooted, flashed CM13(unofficial) with LTE Triband aka "Spark" working, confirmed.
Here is what I know:
1) Sprint Mobile and Boost Mobile are all on the same frequency's.
2) jfltespr Rom for the SPH-L720 also works on SPH-L720T. It's only a Rom, zero difference between the "T" version and regular in terms of the OS, the "T" is hardware.
3) The difference between SPH-L720 and SPH-L720T hardware wise is that the SPH-L720T can receive multiple channels for downloading on the LTE network and the SPH-L720 can only do one, This is the "Enhanced LTE" or "Spark" you hear about.
4) For Boost Mobile, Installing the jfltespr Sprint build for the SPH-L720 or SPH-L720T will not work out of the box. You need to flash the Universal_Boost_APN_Fix-R2.2.zip. After loading in the CM Zip, zip this as well. If you forget, no biggie go back and do it after. This will fix your APN's, label your carrier correctly, which in turn allow you to use LTE, MMS, Triband aka "Spark" (You will not see the spark spiny thing, but it will work, keep reading). Also, side note you may need to wait and/or restart your phone a few times after you are set up with CM. Basically your phone needs to send info to the carrier tower and it all needs to sync up. Mine was fully working in under 20 mins. It's like when you activate a phone for the first time is all.
5) To verify the Triband or "Spark" is working download LTE Discovery App. The Triband or "Spark" Network runs on 800mhz Band 26 for voice, 1900mhz Band: 25 for Up/Down Data, and 2500mhz Band 41 for Down Data but at a higher DL rate. See these articles for more details, Sprint Network Explained, Frequency Faq's
UPDATE: I changed a setting in the MMS, turns out Boost Mobile requires a Username for mobile data to work correctly. This is now Ver. 2.2.

Hi there. What do you mean by "zip this as well"? Do you mean upon fresh installing CM we should also add the "Universal Boost APN" zip at the same time (in TWRP for example)?
I am guessing my issue is totally different, but thought I would ask anyways. I have a Samsung S4 on RingPlus (not Boost, but still an MNVO on Sprint). I have CM12 installed. everything works great except MMS. I can send normal text but cannot send (or receive) photos/multimedia. It complains about APN settings. I have a fresh CM installed so I'm willing to try anything to trial and error this thing.
Thanks for any ideas.

You can flash at the time you install the rom to save the APNs as default, or you can zip any time. However, if you flash after the install your default will be whatever CM's where.
This zip may not fully work for you then, but I did do some googling for you and found this below, if those apn settings work, let me know and I'll try to make a zip for you for future roms and quick flashing

I had to unzip this in Linux for some reason, but after that I got the MD5.
Here is my download if you want it sooner, Sam Mobile is often pretty slow,.... OK3.

@ThomasJoseph315 Every time I flash this zip it says error 7 and will not flash is there a way to get this to work for me I have texts and calls but zero data and I need it for navigation. I am running official jfltespr cm13 on my boost Galaxy S4 thanks in advance.

Did you clear the data, cache and delvik cache first? The only reason I ask is because I made that mistake trying to "test a flash" before I lost all my stuff. Remember, you'll only have the space for the micro Gapps without re-partitioning.
Also, the Boost APN fix didn't work for me, nor the other 9 or so that I tried. Then I came across an old thread where I made a fix for the APN on my old Cyanogenmod setup with my L720 piggybacked off the work of mopedryder. , and I'll be damned. Still works even on my replacement L720T.
Not sure why, but this isn't working with the "Official" build.... Looking into this..
Yea, I was having a bear of a time with the MMS and APN stuff. It looks like they pushed some changes that messed with the "Boost APN fix R2 and also my old fix. What I found works now was hand editing the apns-conf.xml file to just the basics. Nothing but a boost apn and a very cdma apns just in case. Flash rom, flash gapps. After it booted, I copied that in to the /system/etc folder over the old one with file explorer, fixed permissions to match the old file and boom... MMS and LTE after reboot. You can give it a try if you want. Just unzip and copy/paste where I said. Let me know what you get if you try it. Also, let me know if you can edit APN settings while on wifi with this. Just curious. If it works, we can throw it in a flashable zip to flash after gapps.
MMS and LTE working!
I used the flash link provided in this thread Universal_Boost_APN_Fix-R2-2.zip This got me LTE, but still no MMS.
I followed the instructions in the last post, but they didn't work. I kept trying, and had no luck...this was before trying the flash file above.
After getting LTE, I decided to see what I could find inside of the apns-conf file. I checked out the settings and then did some searches for APN settings and found that the line for APN type was potentially misconfigured, so I edited it manually in the apns-conf file, because I REALLY didn't want to flash my phone for the umpteenth time. I also changed the bearer number to "0"
The previous type was: "default,supl,mms,dun,fota"
The type I found through apn.gishan.net was: "default,admin,fota,mms,supl,hipri"
Once I changed that in both lines that the type appeared in and changed the bearer numbers to "0" my MMS started working, as well.
Hope this helps someone out there so they don't have to search as long as I did.
Sprint Samsung Galaxy s4 moved to Boost Mobile
Icky Samsung system, I will not miss you.
Hi everyone, kinda new to the S4 forums. (not Android dev) my current daily driver is a SPARK on boost (running cm13) and my wife has the L720 also on boost. So given that I have the rare opportunity to dig into both activated devices and collect all the radio/modem/APN data from them in order to help this thread and maybe actually contribute something instead of just lurking and reading
So after about 3 weeks of digging and testing and comparing, also trying the edits suggested above on what works for them I have found the proper network settings in the apn-conf.xml. my attempt was to get them as close to the stock ok3 apns as possible and they are very close. MMS works great, LTE shows up right after boot. I also found that after flashing Unerversal_Boost_APN_fix.zip, sometimes mobile data (LTE) would not come back after WiFi was on and then disconnected like when l left the house for work. Toggling airplane mode did no good. Only a reboot would get LTE back. That problem seems to be solved too.
I also took apart the Universal_Boost_APN_fix.zip provided in the op, studied and compared it to stock files and my ok3 modem logs.
In the fixprop.sh, the
sed -i 's/ro.telephony.default_network=.*$/ro.telephony.default_network=8/' /system/build.prop
Command sets the build.prop ro.telephony.default_network to =8
But in both L720 and SPARK, stock boost ok3 the network is =10 so I edited that.
Also I found that
sed -i 's/gsm.operator.numeric.*$/gsm.operator.numeric=311870/' /system/build.prop
Makes the build.prop call for the apns with the numeric tag =311870. but in the apn_conf.xml the apn numeric tag was = 310120 so I just changed the apn to =311870 so now the build.prop will set the right apns on boot.
Something else I found when reading modem logs from both the L720 and the spark is that in the spark, the modem actually calls for
ro.product.name=jflterefreshspr and ro.build.product=jflterefreshspr from the build.prop
I never could find out why it would need that ( and I tried) but my deductive reasoning tells me that it must have to do with initiating tri-band traffic somehow on the network. It only happens on boot but never after that. The L720 ok3 modem does not call for a name from the build.prop at all. So I added commands to the fixprop.sh to change some of the values to the =jflterefreshspr SPARK name and =L720T in the build.prop as well.
Of course, that makes the install.zip proprietary and not unerversal anymore and L720 users would need there own version so here's what I have guys.
All credits go to the original creators of these scripts. All I did was make a few changes.
Flash cm13, gapps(or not), then the APN.zip and reboot.
Note: You might notice after a reboot that the carrier will display as "sprint" but toggling airplane mode then displays "boost mobile" don't worry, it's just a display issue. network and mobile data work with no issues. I think it's something in cm13. started happening around 07/09 nightly
Sorry for the long drawn out post!! :silly:

Will this work with other ROMs as well, or only CM?
I want to flash Wicked X, but I'm on boost.
The apn.zips should work on any AOSP ROM.
Not for TouchWiz ROMs
You don't need it for WickedX.
WickedX will install BoostID and set your apn settings right after it boots the first time just like stock boost ROM. After all, it is just the stock Samsung firmware with a bunch of mods added to it.
AOSP(CyanogenMod) is NOT Samsung firmware. It is compiled completely from a different source which is why the .zips are needed
If you're running CM13 stock, CM doesn't use muppets, with my build I did, so might be tempted to do a build soon, might not, truth be told I kinda gave up because of how much of a pain in the ass CDMA and MVNO's are becoming.
