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?

Thanks man I'll reupload when I get back home with the edited bits . It is the XT883 radio.
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.

I was asking about radio unlock, i know sim unlock is permanent. But has anyone tried to install any rom after the radio unlock and if yes which one?
thanks

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.

I live in Yemen and recently I bought motorola droid 3 by a friend in USA thinking that it will come unlocked as mentioned in ebuy and I was missleaded by the global name , anyway I unlocked the gsm and I am using the cdma for calling but when I went to the cdma company to enable the 3g evdo internet they told me the are unable to set my motorola and the other motorola devices.
the main propose for me to buy this device is to use the internet since the gsm companies have bad and slow internet.
since four three months ago I have been trying to find a solution in the internet but because I dont have much knowledge about android, I could not find what I need.
but I found many useful information in xda and I root my phone and I am glad to achieve this level but still not able to find what I need.
if I change rom can I get full control of my device without lossing any advantages in my device , if so what is the things I am going to loss in using another rom , also what is the best rom to use
sorry if I make it long but I have also to mention the following
the device was new and not activated buy verizon .
rooted
droid xt862
I could not get the apn details to try inter it manually
I need your help please

Try editing the file apns-conf.xml located in /system/etc to include your apn info and see if that makes it stick. You may have to wipe data/cache after pushing the new file

I had hard time looking for information about the sitting with Yemen mobile , any way you have to be rooted to do the following for activating 1xrtt and later the EV-Do
1- ask the company to activate the service for you if asked tell them your phone is ready
2- change the mcc and mnc code in the root -> system build prop
you would find this line
ro.cdma.home.operator.numeric=310004
change the no. to 42103 and save
you can use ES File explorer to do the above make sure the system is mounted as rw before editing otherwise you will not be able to save your changes
no
go to system > etc you would find a file called apns-conf.xml where you can add the apn for yemen mobile use ymobile for the apn name and the user name and password
I suggest you copy the files to other place and edit them when ready rename the orginal files , and copy the edited files. Reboot , ready
Now download apn shortcut from the market and make the apn , ymobile username and password the same ( ymobile , the rest nothing )

im using Sabafon, for you YemenMobile users u gotta be happy, most of the ROM development here focuses on CDMA users, you should try the steeldroid rom or eclipse, just make sure the rom you're about to download is marked "deodexed" so you could te3arribo your phones so u view messages or contacts or whatsapp or any sort of arabic text with no headache of arabic text readers
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?

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.

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.
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 @Dees_Troy for TWRP and just being cool in general
Thanks to @aalyatim for the SSU.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

Hey, guys this is my first post here on XDA so please apologize me for any inconvenience.
I bought LG G4 Sprint i.e., LS991 yesterday from someone else I don't have contact with him now. The sim card which works on 3G was working fine when I bought it. But, then I tried to go in settings and then to mobile network and I opened the list of network bands and unfortunately I was only able to find only two option that are 1. CDMA/LTE and 2. CDMA.
I was forced to select one from it and boom no signals at all and status says searching for service. Where is the GSM option? I'm sure that this phone is already unlocked and it is from Sprint.
Also, I'm on the latest software version that is LS991ZVD. Can I go back to ZV6 International ROM or will it brick my device?!

Bro, I found this on this site:
1. go to settings and add new APN manually (fill the values according to your carrier).
2. in the APN type input "default,dun,fota".
3 .save.
4. Restart phone and you are good to go.
Works like a charm... The signal loss thing happened to me too. Don't select either option after you fix it. Go to backup and reset and reset your network settings. I think this is what I did to solve the problem.

you cannot downgrade has antirollback yuo will brick possibly hardbrick.
i dont know the method but i believe there is possibility even without root but dont quote me on tht
as mine has managed to stay on zv6 since day one
