I still cant get it going. I tried all kinds with every variable and nothing works. Tried H20 sims and Net10 and no success. Ports are up (2 samsung ports), MDC installed, drivers installed correctly, and followed the steps correctly. Those that have successfully got it to work, please input any other things you did it get it to work.
[Sprint Samsung Galaxy S 4 Android Development] spydc:
I really don't know the exact steps I performed to get it working but it took me hours. I actually gave up one day and then tried again the next day. I was using an activated net10 sim card. I was already unlocked for international use by sprint. But I also did use the unlocker software. I played around with settings in the *#0011# menu. Changed hspa release to 8. Edited build prop. Added net10 apn. Hit the watchdog selections.. I just tried everything posted in this thread and I finally got it working.

It's cool because I can easily switch back and fourth between sprint and net10 by using the tellinfo program.
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
Am I supposed to change settings to GSM or leave as is and just change the settings to get of DIAG mode?
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Gsm for gsm n cdma for cdma, remove the phone from diag mode, else it won't be available to your comp for media transfer.
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
I know I am on the right step. I remember it saying invalid sim on the bottom. It doesnt anymore. So something is good there. I just dont know how else to play with it after that or get the sim card to be read.

Update - On my last attempt before I went to bed...got the unlock. Changed something to Rel 8 and worked. Thank you so much to all.
[Sprint Samsung Galaxy S 4 Android Development] sikander3786:
Thanks a lot to everyone for this amazing thread.

I am having a few problems while trying to unlock this phone.

1. Dialing ##3424# asks for a password "Enter MSL". I have set my phone to "DM + MDM + ADB" by dialing *#0808#. Would that work?

2. Dilaing *#9090# also asks for the same "Enter MSL" password.

3. When trying unlock with "S4 L720 Unlocker", the software just hangs and no reboots happen at all. I have waited for 30 minutes. I have 64-bit install of Windows 7.

I would be glad if someone here could assist me.

Edit: I've made sure that there is no driver problem at least.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Are you on MDL or MF9?

If you are on MF9 then, downgrade to MDL modem. Then try again.
[Sprint Samsung Galaxy S 4 Android Development] sikander3786:
I already flashed MDL modem but now I have noticed. that in download mode, there is "Write Protection: Enabled". Probably means that the modem wasn't written to the phone.

Do I need to unlock the bootloader or something else for that?

Check under settings. Which baseband are you on.

[Sprint Samsung Galaxy S 4 Android Development] joeminati:
I did a field test going about in NYC.

It seems that the signal connection to the Net10 ATT sim keeps dropping. And when it does have signal, its only on edge and the E sign freezes for some time.

I kept switching between GSM\CDMA and such settings and not sure what to keep it at. All I do know is that when on GSM, the signal retains longer but still no H+ after configuring APN.

What are the specific radio settings to keep it on so there is less of a drop?
[Sprint Samsung Galaxy S 4 Android Development] sikander3786:
It is L720VPUAMDC.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Connect the phone to pc. Now under device manager look for com ports, there should be 2 com ports with ssmsung label on it. This is to check if you really are on diag mode or not.

Try changing your usb cable n give it a shot again.
[Sprint Samsung Galaxy S 4 Android Development] sikander3786:
Yes there are 2 Samsung com ports under ports in device manager.

I have already tried with 2 different cables and 2 different PCs. :(
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Ok I got tmobile working att is still a no go.
[Sprint Samsung Galaxy S 4 Android Development] sikander3786:
Ok, so this was the problem:

"Make sure "PDA" is selected in the initial ##3424# menu.... not CDMA Modem."

Re-read the whole thread and figured it out. Sorry for asking questions without reading.

A bit off-topic but can someone help me with "Hands Free Activation" as my SIM isn't working even after unlocking. Probably, the phone needs to go through all the activation process, right? I don't have Sprint coverage here and probably that is why it keeps failing.
[Sprint Samsung Galaxy S 4 Android Development] spydc:
I had the same problem with my NET10 connection. I just had Edge data and it seemed to time out. There seems to be a billion different NET10 APN settings. But I ended up downloading the Tellinfo app and use that to change my preferred network mode to "WCDMA Only" when I want to use my Net10 sim. It connects quickly at H+ data. When I want to switch back to sprint, I change the network mode to "CDMA auto (PRL)". It quickly switches it back to sprint. No need to restart the phone.
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
Can you inbox me the settings your using for or show here for others to see.

Also, any other specific settings in the debug menu I should have?

I remember messing around with the fake security and some stuff when I was following the international version unlock I found online.
[Sprint Samsung Galaxy S 4 Android Development] Kevin36:
i finally got it to work but signal sucks big time it keeps dropping.

T-Mobile Working ? Are you actually using a the sprint s4 on t-mobile network ?

I unlock but no signal with lycamobile - t-mobile - att

[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Download tellinfo then press device info then go down to the network info and change it to wcdma only. Here's the link https://play.google.com/store/apps/details?id=com.aebeinroth.telinfo
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
Yup... i did that and I get zero connection when I put it in WCDMA. Only GSM AUTO PRL and GSM only works.

The *#9090# menu I have is set to DM over UART if that matters.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
If gsm is working , then what's the problem ? Data ? For data you need to edit build.prop so that you can add APN of your gsm network.
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
I did. I changed the build.prop and all that was instructed. Also added the apn and nada. I did try to auto set the APN with the HiApn app and didnt let me do anything except when I could, it was in another language which freaked me out. lol So I deleted it.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
You del hiApn ? There is a way to uninstall it. if you del it your data won't work. Because when you install it, its installed as system file.
[Sprint Samsung Galaxy S 4 Android Development] spydc:
Go back to the uim class menu and select option 2 - GSM. It will now switch back to umts.
[Sprint Samsung Galaxy S 4 Android Development] joeminati:
Okay guys. Works great now. It was the UTMS which messed me up. Works good now.

I am in there like a pit bull on a poodle.

Donated a little something for a beer. ;)
[Sprint Samsung Galaxy S 4 Android Development] spydc:
Cool. Glad it's working now. Now you should be able to select "WCDMA only"

Well there are several users including myself that have been using it on domestic GSM networks. I have it running off a NET10 prepaid sim which uses the AT&T network.

Does anyone know if LTE for AT&T and/or T-Mobile also work? Or does our phone only support hspa+
[Sprint Samsung Galaxy S 4 Android Development] wright1026:
I am having some trouble and hope someone can help. I went overseas to Amsterdam and went thru this process when i was in Amsterdam. The voice worked fine with Libra service but i could not get the data to work. When i returned to the States the phone voice works fine but when i try and turn on the data the phone resets. I tried redoing the process with the same results. Any ideas? How can i relock to start from the beginning?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
HSPA+ only. LTE is only 1900mhz band 20
[Sprint Samsung Galaxy S 4 Android Development] clip3009:
Its actually band 25 for lte on the sph-l720

I wonder if theres a way to unlock this. I have tried selecting band 4 under "band preference" in the test mode menu but nothing happens.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Thanks for the correction ive tried that option to and lte on band 4 is not a go I think those options were there so Samsung wouldn't have to create different hidden menus for each S4.
[Sprint Samsung Galaxy S 4 Android Development] Eddy315west:
So what exactly is stopping us from using a usa at&t simnor a tmobile sim in our devices ?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Another lock in the software is stopping us.
[Sprint Samsung Galaxy S 4 Android Development] Febby:
This device by nature should have those LTE bands but just not unlocked for use. I could be wrong here!

Has anyone tried using the qcn file from a Verizon s4 via qpst to see if it unlocks the bands similar to how att s4s unlocked the bands for T-Mobile usage.

Here is a link to the att thread.

http://xdaforums.com/showthread.php?t=2291589

Just don't use the the qcn file in that thread unless you feel like experimenting. Try to get a user with a Verizon s4 to do a qcn back up as shown in video and restore on sprint s4. I'm not sure what results will yield so proceed with risk. :)

Dial ##3282# you should see view and edit, click on edit, it will prompt for MSL, type any random 5 numbers and hit enter, this will give you a error. Immediately type the command in terminal EMULATOR without quotes "getprop ril.MSL" that should reflect your SPC/MSL code.

i still cant get tmobile to work after following the screen shots posted earlier, do you manually reboot the device after hitting watchdog 6 times? or does it just reboot by itself?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Manualy and make sure the tmobile sim is in during the whole process and make sure you do the international unlock first.
[Sprint Samsung Galaxy S 4 Android Development] WW3:
Yah, i had sprint ota unlock it, as well and i ran the unlocker from the first post as well. I don't get the invalid sim error when tmobile sim is in there so i am pretty sure it is unlocked. I had the t mobile sim in there the whole time, went through the steps, and did the both watchdog step six times and nothing happened so i pressed the power button to restart the phone after which i still got no signal.
[Sprint Samsung Galaxy S 4 Android Development] spydc:
Try the steps below for potential of unlocking Domestic GSM. Please note I have successfully connected with NET10 (AT&T) microsim. In addition, I was already unlocked for international use via Sprint OTA. I also ran the sim unlocker software. All credit goes to OP and those that have contributed to this thread.

1) Insert Microsim

2) Run sim unlocker program as described in beginning of this thread.

3) Enter "ServiceMode" menu by entering *#0011#

UMTS Main Menu

1 Debug Screen -> 6 Phone Control -> 1 DRX Control = GSM DRX: ON / LTE DRX: Enables RX0 and RX1

1 Debug Screen -> 6 Phone Control -> 2 Fake Security Control = ON

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 1 Ciphering Control = OFF

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 2 Integrity Control = ON

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 3 Sim Class Control = UMTS

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 5 RRC(HSPA) Contrl -> 2 Change Revision -> 5 Release 8 (HSPA+)

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 7 NAS Avoid Security Control = 2 Security_check: OFF

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 8 BIP Block = 2 BIP Unblocking: set 1

4) Reboot after entering options in step 3. Go back to "ServiceMode"

UMTS Main Menu

1 Debug Screen -> 6 Phone Control -> 5 Simulation -> 2 SW Watchdog <--hit this 6 times

1 Debug Screen -> 6 Phone Control -> 5 Simulation -> 3 HW Watchdog <--hit this 6 times

(Manually reboot phone)

5) Go to Phone Settings -> Mobile Networks -> GSM -> Maually Search for networks

6) APN Settings

If you are using AT&T and/or TMOBILE branded sim you can do the following:

1) Install "HiAPN Global" from playstore

2) Select "Click to AutoSet APNs" then reboot

If you are using prepaid sim cards that require specifc APN Settings then do the following:

1) Edit build.prop (Must be rooted)

2) Install NovaLauncher from playstore

Launch NovaLauncher and create APN Settings shortcut by doing the following:

a) Long press on home screen and select "Shortcuts"

b) Select "Activities"

c) Select "Settings"

d) Finally select APNs

After shortcut is created, go into APNs and add/edit APN info. At that point you can go back to TouchWiz or stay with NovaLauncher

7) Install "Tellinfo" from play store. (This app allows you to seamlessly switch back and fourth between Sprint CDMA and GSM (WCDMA) on the fly. No need to reboot

1) Run Tellinfo app and select Device Information

2) Scroll down to "Set preferred Network Type" and choose

a. WCDA Only to connect to GSM Networks

or

b. CDMA auto (PRL) to connect back to Sprint network.
[Sprint Samsung Galaxy S 4 Android Development] WW3:
I went through the settings but every time i set it to gsm/lte or wcda only i see this circle with a line across instead of the network bars. It connects to sprint as soon as i put it cdma using the Tellinfo app.

Its sign like this one where it would show how many bars i have:

I am in middle of nyc, so i don't see why i wouldn't get t-mobile signal.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Redo the instructions with the sim in and the phone on gsm/umts mode.
[Sprint Samsung Galaxy S 4 Android Development] WW3:
hmm... still cant get it to search for signal, still that circle with line across it. Could it be the rom i am on? Im on MDL with blukuban rom.? Also when i punch in *#0011# , i get this service menu but not with the 1-6 options, so i have to press menu, back then enter input 1 and then i get to the regular menu shown on the screen shots. Could this be affecting the domestic unlock?

Kind of like step 2 shown here : http://gs4.wonderhowto.com/how-to/carrier-unlock-your-samsung-galaxy-s4-so-you-can-use-another-sim-card-0148110/
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Dail ##27663368378# it should take you right to the menu with options.
[Sprint Samsung Galaxy S 4 Android Development] xuser:
To go back to full Sprint CDMA/LTE coverage, do you have to reverse the settings, or can you just keep them, change the SIM card back to Sprint and revert to the Sprint APN? Thanks!
[Sprint Samsung Galaxy S 4 Android Development] WW3:
The phone tries to call that number when i type that in and press call. Nothing happens without pressing call.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Your not supposed to call it should take you to this menu. Try using a stock rom.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
So I'm in the Philippines and successfully using local carrier pre paid. Phone, sms and internet all work.

I was wondering though I'd there is any way to take advantage of the lte plan i signed up for (says it supports speeds up to 42mbps). Currently, my signal shows h+. Sometimes it will bounce between h and h+. I recall someone saying I needed to use nova launcher to create a shortcut to testing menu and in there change the mode to wcdma only. I've done this but still only get h and h+. Any way to unlock and take full advantage of lte?

This is on my galaxy s4 home carrier is Sprint.
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
There unfortunately isn't. It's locked to Sprint's LTE band.

[Sprint Samsung Galaxy S 4 Android Development] autoprime:
LTE would only work if the carrier used 1900mhz(band 25) LTE.

here's a list of carriers and LTE bands used - http://en.wikipedia.org/wiki/List_of_LTE_networks

Sprint's pretty much all alone with band 25 :(

in the future this may change... with LTE chips supporting tons of bands at the same time... but for now.. Sprint devices are good for Sprint LTE only. Even with Sprint's new "tri-band" LTE which uses 800 and 2600mhz.. isn't used by most other carriers. The new Nexus phone looks like it will have ATT.. TMO AND Sprint LTE bands.... which would make the phone usable just about everywhere in the world... and with the ATT/TMO LTE bands... LTE would work in a lot of places too.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Have you added any lines in your build.prop to enable edit option for APN, then remove it or put a # in front of those 2 lines.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
See attached picture, looks like I am sol!

On a side note is h+ going to be the fastest speeds I'll get?
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
yes, hspa+ is tops.. unless using wifi ;) the hspa+ seems to max out at around 14mbps.

or unless you use it on Sprints network.. then LTE may be faster.
