For those of you who want to use your Sprint Galaxy S4 SPH-L720 as a GSM worldphone, you can get your unlock SIM code from Sprint.com. Now, sometimes even with that, your phone may not work correctly, here’s how to manually unlock SIM on your Sprint Galaxy S4 so you can use use phone when traveling abroad.
*Note – Currently, this unlock method only supports carriers outside U.S., will not work AT&T or T-Mobile. But I should have an update when there’s a way to do that also.
Before we begin, I suggest you to use a TouchWiz-based ROM or stock ROM for this.
Step 1. Go to Settings->About device and check your Baseband version. If it ends in MF9, you will have to downgrade to MDC. If it ends in MDC or MDL, you can skip to Step 6.
Step 2. Turn your Sprint S4 off then hold down Volume Down, Center Home, and Power buttons together until you see warning screen.
Step 3. Hit Volume Up button to enter ODIN Download mode and connect a micro-USB cable from your S4 to your computer.
Step 4. Next download MDC modem for Sprint Galaxy S4. The file name is “SPH-L720_MDC_Modem.tar.md5”.
Step 5. Next open up ODIN program (download ODIN here if you don’t have it yet) and run ODIN.
You should see a yellow-highlighted box, if you don’t see it, you need to download and install Samsung USB drivers.
Next, choose “PDA” and find the file “SPH-L720_MDC_Modem.tar.md5” you downloaded earlier. Then hit the Start button. This will flash MDC modem to your Sprint S4.
Step 6. Once rebooted, you will see that your Baseband version says “MDC”. If you don’t see this, try repeating Steps 2 through 5 one more time.
Step 7. I found out after doing this, I didn’t need MSL code for this tutorial. You may need it though so come back to Step 7 if you end up needing the MSL code but you should be fine without it. so Skip to Step 14.
Next, we are going to get the MSL for your phone. To do this, go to Settings->About device and hit the Build number about 5-6 times until your phone says, “Developer mode has now been enabled”. This will allow you to get Developer Options menu.
Step 8. Make sure “USB Debugging” is checked ON under Developer options then connect a microUSB cable from phone to your computer.
Step 9. Next, dial ##3282# on your dialer.
Step 10. Press “Edit”.
Step 11. When it asks you for MSL code, just enter “123456” and hit OK.
Step 12. Next, download and unzip fastboot.zip.
Step 13. Open a command prompt (by typing “cmd” in Windows search bar), then type:
cd Downloads
cd fastboot
adb shell
su
getprop ril.MSL
This should give you your MSL number for your phone. Write it down somewhere.
Step 14. Next dial “##3424#” on your dialer.
Step 15. Choose “Qualcomm USB Setting”.
Step 16. Choose “DM + MODEM + ADB” and hit “OK”. Then connect a microUSB cable from your phone to your computer.
Step 17. You can verify everything is working correctly if you see TWO Samsung Mobile USB Serial Ports under Device Manager->COM & LPT.
Step 18. Download unlock.zip and unzip. Then run unlock_setup.exe. This should install the program that unlocks your Sprint S4.
If you get an error saying you need .NET Framework 4.5, download it here then re-install program.
Step 19. Once installed, you can run a program called “S4 Flasher”. Run it then choose “Scan and Unlock”. It should say “Completed. Phone rebooting.” If you see that, your Sprint Galaxy S4 has been fully unlocked.
Step 20. Once your phone reboots, dial “##3424#” on your dialer.
Step 21. Set it back to “MTP+ADB” and hit “Save”.
Step 22. You can now test your Sprint S4 by inserting another SIM card. You shouldn’t see invalid SIM card error message, meaning your Sprint S4 is fully unlocked.
Note that this method doesn’t work currently for AT&T and T-Mobile. We suspect that Sprint has locked it down for use on other U.S. networks.
As for non-U.S. networks, it should work fine. Also, you may have to set APN manually by using APN Manager PRO. (You can take a look at Note 2 World SIM method for more on that.)
I haven’t had the time to test outside U.S. yet (obviously because I am in the U.S.) but if you can test it outside the U.S., don’t forget to leave your comments/hints below.

Will this unlock make it work for metro PCs?
So how do you do this on Mac OS???
Help, my baseband is ng5
What I can do?
I tried this method and it worked for me! I’m in Europe, bought my phone in NYC a few weeks ago, and now Im using a macedonian network. One thing to remember, watch the video instead of following the instructions on this page, since the video has a few explanations that aren’t on this page; like for example that you have to pick your network manually after you are done with everything. Oh, I also couldn’t get through the MSL part so I just skipped that step and it still worked.
Good luck!
did you apn settings work? how did you go around that?
Hey, no I didn’t get it to work and I have no idea how to. I just don’t have the settings in my phone, they’re missing. Hope someone figures a way around that.
From the stuff Im reading around the web, it seems we need to root our phones first, and install custom ROMs. I’m really not good at that stuff. Also, I don’t know if rooting will screw up the unlock…
yes you do.. actually i got it to work that same evening.. follow this thread .. works great..http://forum.xda-developers.com/showthread.php?p=44903664
no custom rom necessary.. just root the device for access
Did you root your phone before or after you unlocked it? I’m afraid it might ruin the unlock somehow. Also, did you root it by following instructions off of some website? If so, can you please tell me which? Thanks!
i rooted it after unlocking… i went that direction because it appears thats the only way to get the data to work.. i only noticed the data wasnt working when i took it to the telco for apn settings… there was already a sim in there at that point and making calls
no you dont need to root it, if you didnt revert back to the baseband stock rom you wont be able to det into DM mode…
New easy method: Root Required
1)Go to market install BuildProp Editor
2)Once installed find and open Build Prop Editor
3)Hit the Edit button (pl See 1st screenshot)
4)Scroll to the bottom of screen and add the following lines
Code:
ril.sales_code=LOL
ro.csc.sales_code=LOL
5)Hit the save button at the top right hand corner of the screen(looks like a disk) (See 2nd Screenshot)
6)Once this is done saving restart the phone
7)After restarting go to Settings>More Settings>Mobile Networks>Access Point Names>Menu Button>+ New APN
8)Add desired carriers APN info, when finished hit menu button and save
I’m from Mexico and i’m using this since 2 weekends 😉
Sup Kevyn… what is it that ur using? I am trying to unlock my sprint sg4 as well that I just got… you mean the unlock they use? or buildprop?
This is just fot apn settings using buildprop man, you can get it from play store, i unlock my phone with the method of this page 😉
Help me Kevin
I want to unlock a galaxy s4 form telcel, I have done the buidprop thing but the apn disappears after I save it.
Me puedes ensañar como hicistes para desbloquearlo yo compre el celular en estados unidos por At & ty vivo e colombia y no pueddo utilizar mi sim y me dule pagar 30 usd por el codigo Porfabvor ayudame
OMW! Thank you so much Kevyn! I am in Jamaica and I was so pissed when I came here and realized I couldn’t get data services because APN wasn’t available in phone. Tried a number of things but they didn’t work. What you recommended was the easiest method I have seen. At first I didn’t get what you meant by go to market but then I figure you meant PlayStore. I am officially happy now. Thanks again! 🙂
Your welcome man
This didn’t work for me…had to download HiAPN, from market, its the easiest method. Once downloaded just launch the app, it’l id the network and all the parameters. Reboot your device and see data connectivity in the notification on top. Its 100% possible.
Hi I skip step 12 and 13, I did root with odin and install (MSL utility apk) on my s4 and give me the msl code; more easy!
I have a Sprint S4 and I can’t get my MSL to work .
What did you to make it work?
UsE MSL UTILITY APK AND GIVE MSL CODE FAST
i dont see the two modems as expected in step 17. as a matter of fact the usb modem only appears in odin ( downloading” mode.
so on that note the s4 flasher does not complete since it doesnt see the modems.. where did i go wrong?
excellent piece.. works great!!
at the adb shell it keep saying device offline… how to fix this?
peter.. verify the drivers are installed.. and appears in the device mananger.. i also had difficulty there but i used 3rd party msl reader…
I used a 3rd party MSL reader and finish all the steps, but its still not unlock. it won’t read my att sim, it said invalid sim
If i flash a custum rom, will the unlock still work? Is this a factory unlock just like the at&t model with an unlock code?
Peter.. :Note – Currently, this unlock method only supports carriers outside U.S., will not work AT&T or T-Mobile.
eduardo: suggest you to use a TouchWiz-based ROM or stock ROM
Did anyone on here get the mobile data to work? how do you add apn settings?
Thanks a lot! I owe you guys, like seriously Finally worked the second time but I didnt hit ok after selecting the modem + Adb + DM part that was when it worked even though when I ran the s4 flasher it complained that I did not put the phone in diag mode then rebooted and everything just worked out great. Thanks once again
Hi, I have the same problem with the s4 flasher complaining that I did not put the phone in diag mode……Please give me a step by step of how u resolved this issue. Thanks

Hi, Step #19 talks about downloading S4 FLASHER, but it does not give a link where it is downloaded from. I tried to find it online in vain. On the instructional video it appears as S4 unlocker, which made me confused. Could you please advise on where I can download it from so I can scan and unlock my phone?
Also, do I have to have a Sprint sim on the phone during this whole process, or it doesn’t matter if I have it on the phone or not? My phone did not come with a sprint sim.
step 18. it isnt called s4 flasher untilyou extracted and install it should appear on your desktop.

Have a Sprint S4 Galaxy.
Downgraded the baseband as suggested as could not access the menus.
Followed all the instructions above and in the video, Seems to have done something. Won’t work with ATT or tMob sims, now need to test it outside the US to confirm it is unlocked
how long does it take after clicking the scan and unlock button. it says completed. Phone rebooting. but the phone has not rebooted yet??
I am having the same problem. Please help.
im stuck there as well:(
hi i have the sprint s4 with the new software BASEBAND VERZION L720VPUEMJA. I update my phone few days ago. . so is this baseband low grade method will still work on it.
i tried it with a mexico sim card, but it’s still not working. It don’t show up invalid, but not reading my sim card.
I just got my sprint today and after watching the tutorials above I managed to unlock it.
Am using it on a GSM network in Norway and its working perfectly well though I do not
have data, am hoping I call the mobile provider to activate my line or send me the internet
settings. I have not tried the wireless but it managed to ID some networks around, meaning
its good to go.
Am also optimistic that it’ll work in Africa. Will get you guys posted when I get there in
7-8 months time.
G Thanx man!
Am now in trouble guys, desperately need help. My mobile service provider can not send network generated internet settings to my phone. They instead sent manual instructions which I seem to have issues inputting in the galaxy s4 (sprint ) does anyone know how to do this? I have no mobile data but wireless is perfect…
this is a common problem which I would also like help with the phone does not show you apn settings at all they r not grayed out there r not there totally
kent try to download HiAPN, from market, its the easiest method. Once downloaded just launch the app, it’l id the network and all the parameters. Reboot your device and see data connectivity in the notification on top. Its 100% possible. Let me know if you manage or not
yes Hi Apn just downloaded from App Store do not remember is neccesary to be rooted
Can this unlock be used for simple mobile?
Will this work with a Net 10 sim card?
I’ve unlocked my phone, but chances are it won’t work with Straight Talk will it?
Do i need to have a SIM card in? i lost mine
You can root your phone with whichever sim card you want or better still without any. However after you finish rooting try check if you got SuperSu in your apps, this will tell you that your phone is rooted. Put in your desired card. Youshould be able to place calls. Good luck
I did it with no sim card and no problems
It worked! Thanks. i’M IN THE CARIBBEAN.
cindy 101
did u experience any issues with Digicel’s network? seems to be working fine with LIME but i am experiencing some issues with digicel
It worked! Thanks.
WELL…. 123456 DOES NOT WORK ON MY SPRINT S4. IT CONTINUES TO SHUT MY PHONE DOWN. THANKS. NOW I HAVE NO PHONE.
@ Rebecca try follow the vid and not the instructions. Remember the basebands and the model # as well as which base model you want to either downgrade to upgrade to. I’d advise you to downgrade and if possible, try axing someone to help if you are having trouble as this is a very simple procedure.
All da best!
@Bronda, I followed to video. The 123456 doesn’t work 🙁
I have not phone right now and I was hoping I could get this S4 off of Sprint to put it on CSpire/Cellular South. I am so frustrated. As far as finding someone to help, I am the only one of my friends who is “tech savvy”. I don’t know what to do. I don’t have an extra $150 laying around to take it to a store to have it unlocked. 🙁
Oh well, no phone, no one to bother me I guess. I don’t know. I need one but I will be fine. I will just resale the ones I have. My CSpire phone CRASHED yesterday and will not do diddly squat.
@Rebecca how’s it going, did you have a go at it again or you gave up completely?
Hi, can you help me please, In the step 13 i put the command adb shell, and appears shell@android:/ $) but in your video appears (root@android:/ #)
how i can be root@android:/ # please help me
im having the same problem he is having.
To get root type ‘su’ and hit enter. Should grant it root access. Assuming you have it.
In that case, skip the command “SU”, so you need to type “getprop ril.MSL”. It worked for me
im having this same problem. any help please!!!!
same problem, what can I do to solve this?
everything worked fine for me but when i tried to open s4flasher i got the no a 32bit valid aplication message. so i unlocked with z3x box. just saying.
Excelent! It worked for me. Now im using my samsung s4 in Latin America and its working perfectly. Thank you very much for this post.
Hello, I’m trying to follow this instructions, but my baseband actually ends in MK2, does this downgrade should work for my phone as well?
hi, i am having password problem after ##3282#
edit then password 123456 is not working
sorry, my bad, so i get to root the phone then getprop ril.MSL but it did not give me any code for MSL 🙁
were you able to figure out?i too am not getting any MSL code. and the ##3424# code is prompting me to enter the MSL code, so am stuck.
Question, once the phone is unlocked, will it still work with mah Sprint SIM?
I have another question, what if the last three letters of the baseband are MJA?(that’s what I have)
I cant get the Odim software to open after it’s installed.
May i know whether it works for SC-O4E (Japan NTT docomo) or not?
what if my s4 baseband ends with mk2
I have Sprint Galaxy S4 with stock 4.3 and MK2 baseband. Is it possible to unlock this phone? I need tutorial.

Hi everyone,
I have followed these step and unlocked my Sprint galaxy S4. and I tried over sea in Asia worked great on GSM network. I also add some comment for some who could not get MSL CODE by using Fastboot as show above, you also try this to download app to your phone and get your MSL Code : https://dl.dropboxusercontent.com/s/…sDoVMQxrfELn5A
That where I got my MSL code from.
It works for my galaxy S4 4.4.2.
Good Luck
Hi,
Is there any similar unlock for the Sprint Samsung Galaxy S5 ?
I did all the procedure but when in put this command ( getprop ril.MSL ), I don’t see the MSL number for my phone!!! Why???
Try from your phone go to website forum http://forum.xda-developers.com/showthread.php?t=2710885 , find user “Daniel4653” and click on the link https://dl.dropboxusercontent.com/s/…sDoVMQxrfELn5A then download the app.(MSL Utility) when done open the app. then hit read SPC will show your MSL #.
I just unlocked mine which has 4.4.2 version, also might work for lower version.

I’m in China now and my Galaxy S4 Sprint work very good
Is there a way to unlock Sprint Galaxy S4’s for U.S. domestic use. This is the closest I have gotten so fare.
Respectfully,
M.
Does this work on any android version?
I did it on one Galaxy S4 L720 Sprint with android 4.4.2 and it worked like a charm.
Tried on another S4 same model, just that its android 4.3 and didnt work. (Cant update to 4.4.2, its stuck at 5%).
I did not get the mls code is for what?
To get into the system menus you need MSL code on Sprint phones.
i need help. 2 thing.
1 when i typing cd fastboot on cmd say ( the system can not find the path specified).
2 the fastboot file only have 2.4 mb and the file on the video it have 1.4 gb whats happening ??
I have the Sprint Galaxy S4 SPH-L720T. The baseband version is L720TPUBNC6. Can someone please help me find the method to unlock it.
Oh and it is currently running CM10.2.1
Need help as well unsure what to do my baseband version number end with FNAE what do I need to do now?
Hello,
I’m in America and just followed step by step flawlessly. Running 4.4.2 on Sprint L720, downgraded baseband to MDC and confirmed the stick. I have a Swedish SIM card inserted and its still showing “invalid SIM”. Is this supposed to go away? I want to some how confirm unlock before I’m overseas and SOL.
Thanks!
Didn’t work for me … no rebooting … nothing happened .. any ideas
I unlocked one L720 running 4.4.2 and worked but on this one with the same version, everything is the same, kernel, baseband, etc., it doesnt work. I noticed now it doesnt say “Invalid sim: but it wont get signal. any help?
Hi,
I was hoping for a little help since I can’t really find anything regarding my issue. I have unlocked and rooted my SPH-L720 and it works fine. But I’d like to update to 4.4.2 (am running 4.2.2 right now, stock ROM).
Will everything go to hell?
I tried this method in order to use Sprint Galaxy S4 in Korea.
I was sort of lost in the middle of CMD procedure (step 13) but I just ignored and gave up to get MSL number because I couldn’t find where I needed to use this number later.
Then, I moved on to remaining steps.
And, it worked. I didn’t even need to install .NET Framework.
So, I bought USIM from ‘SK telecom’ and it worked. Yeah.
I did it in Korea. Thanks a lot.
Hi, my phone is Sprint Galaxy S4 baseband version L720VPUFNAE. I can’t access this function with it. I need to unlock SIM card. Do you know how can I do it in this version? Thanks!

Im trying to conect to Telcel (Mexico). Thanks!
Hi: I tired so hard. Everything seems to be normal in the terminal, but after i wrote te getprop ril.MSL nothing happens. I already tried at the Android terminal app but same thing. My phone its already rooted. Thanks for your help
Thanks, This works for me for s4 which based band end with NA*.
can i sim or carrier unlock sprint s4 to use in us?
My phone baseband version ends in NAE to do something with. Thank you
hi,
I have my baseband version ending on ****BNC6,,,,
so , can i just the download steps too.
on step 13 , while doing the adb command on DOS
I get another msg saying “adb is not recognized as internal or external command, operable or batch file.
THank you.
Thanks so very much. it worked for other versions. I wish I could use it for my Sprint “SPH-L720T version. Is there a way out please???
I followed the instructions above and everything seemed to work fine but when I inserted my SIM it says it’s invalid and the phone seems to still be with Sprint. I’m in Canada so I’m not sure if that has anything to do with it. I also had to root my phone for it to work as well. Any suggestions?
I got it unlocked now but the SIM doesn’t work. A new SIM will work for a second or 2 but then it doesn’t recognize it after that at all. Has this happened to anyone else?
hi, it works for me but when i connect to my wifi they prompt the new android update, if i choose and accept will the unlock go away and stuck again or will all stay the same with no problem? plz help and thanks for ur hard work
I don’t think it’s related with your SIM unlock. So safe to say yes.
I am in Costa Rica and was able to unlock my Samsung Galaxy S4 which I used while living in Las Vegas, Nevada with the carrier Sprint by following these exact instructions. It is now GSM compatible and working with Kolbi ICE network. The only part I could not get was the MLS number in Step 7 but I did not need it. So just let you all know if you download all the programs and files first and put them on your PC and follow each step it should work.
I REEEEALLY need some help! I somehow screwed up my unlock, so I tried to do it all over again, so I start from step 14 as for the instructions, but when I punch in ##3424# and hit dial I get “mobile network not available”
Any ideas?
accutaly i did this but when i entered the msl password i said its incorrect password..
what to do next any body there??
Try getting the MSL code again, double-check it’s the correct one.
im stuck on step 1 because my baseband end its different it ends with PUBNC6 and when i run the odin program and where it is supposed to say MDM says fail and the baseband doesnt change

Hi. After 4 daya of searching I found your great youtube video.
big question. I now know how to enter my msl thanks to you;)
Now how do you enter nck code. I have the number. Sprint gave me msl and
nck so I can use it in canada and use the gsm side on my samsung sprint mega
and no one in canada or the town im in. Toronto knows how to input the codes or
do a unlock.
im half way there thanks to you.lol
please!!!!!! IVE HAD 4 DAYS OF HELL. Can you tell me how to input my nck
code.
I figures the s4 is like the mega and maybe ill let a 3rd party unlock store follow
your video in case I cant find a way to input the nck code.
Thanka

hey this i could unlock s4 sph l720 m works like a charmo im having problem with the data connection though
i contacted wd my service provider he is unable to send details of my APN … so i was thinking should i root it and install the build prop editor model
this unlock method works on SPH-L720T ?
Did you find a method to unlock the SPH L720T please let me know
I am using a Sprint GS4 in Canada.
I did this method last night (Skipped the MSL number part) and it worked like a dream.
“Invalid Sim” warning was gone.
Phonecalls were coming and going.
I have a problem though… there is no data connection.
Not texts, no internet.
I saw the Build.Prop thing and downloaded that, but everything I go to save the changes, it says: Failed to Save BuildProp.
I paid for a “better” buildprop editor and it says it couldn’t allow any edits because the Phone wasn’t rooted?!?!
I thought this method rooted the phone?
I’m not sure what to do next.
I called my carrier (telus) and they are a bunch of blind, tumbling retards about it.
Do you have any idea how I would get back data connectivity.
Thanks.
And thanks for the above tutorial.
im having trouble in step5
SPH-L720_MDC_Modem.tar.md5 invalid
what should i do???
So I got this work work and running on T-Mobile.
Anyone tried to upgrade the ROM to T-Mobile to see if you still retain the unlock and connection setting?
Thanks.
hi my baseband dont ends in ng2 work for my phone or i need to downgrade or what
I change the mother board on the SPH L720T with a SGH i337 mother board so that I could use the GSM sim the only issue I have is the menu buttons don’t work at the bottom home button is ok any ideas
the i337 motherboard will not fit in the sprint housing. and the menu button assemblies are different on the S4s
Thanks for the info, just wondering if anyone has unlocked i257m S4 mini, baseband i257mvlubng1 runing 4.4.2?
I’ve tried rust about anything i could find on line with no luck, any solution yet?
Once I unlock the sprint s4 will it work on metropcs?
My baseband version ends with NG2.
What Should I do?
Please Help.

Will your method work with T-mobile carrier now? or only work with carrier outside the States?
Thank you so much, Sir.
ODIN is always not responding every single time that Im trying to flash my s4’s ROM. Help me to fix this please. Tried other versions of ODIN as well. Tried to use different laptop but still not working. Currently using Windows 7 Ultimate. Thank’s in Advance! Cheers!
Just wanted to say that after switching to a Win 8.1 PC the and using SPH-L720_MDC_Modem.exe did the MK2 to MDC modem downgrade go exactly as it was supposed to… allowing international carrier unlock… after following all the instructions in detail on a rooted Sprint SPH720 Samsung Galaxy S4 with stock factory ROM. Odin 1.85 (multiple attempts) wasn’t doing it. http://rwilco12.com/downloads.php?dir=Files/Devices/Samsung%20Galaxy%20S4%20%28SPH-L720%29/Modems
Thanks to all the amazing work by xda-devs http://forum.xda-developers.com/showthread.php?t=2415587

Does the phone have to have android version 4.2.2 for this methos to work or can i do it with 4.4.2 ?
Is there any new updates that let you unlock from sprint to t-moble
Thank you!!!!! i just unlocked my Sprint SPH-l720 with this method. i just couldnt obtain my MSL Code with your method i used SPCUtility.apk after obtaining my MSL code Everything worked out perfectly!! 😀
Hey, I haven’t seen a way to unlock the gs4 sph-l720t on the Sprint network yet. Any chance this method would work? If not, has anyone found a way yet? Thanks
Is this tutorial specific to S4’s with baseband versions ending in MF9? My S4 ends ends in FNG2 and I am unable to downgrade to MDC/MDL. The ODIN program simply freezes after I hit Start.
Any suggestions are welcome.
Remarkable! Its actually awesome article, I have got much clear idea concerning from this article.
hola que tal, mi mi banda base es L720VPUFNAE no termina ni en MDF ni MDC ni MDL .AYUDAAAAAAAAAAA POR FAVOR lo compre en usa. y actualmente estoy en argentina.
My phone is not rebooting after I click unlock button. .
Hello, Max.
I tried and got the phone (Sprint Galaxy S4 L720T) rooted, I even ran S4 flasher (it said that it worked), but…. phone still cant recognize different sim (on GSM band). Software version – L720TVPUAMK5. Hdwr version – LT720.03. Android 4.3. build # JSS15J.L720TVPUAMK5. I even tried to change the networks to GSM and auto – no luck.
I did not downgrade to MDL – couldn’t – something did not work.
Let me know if I made a mistake somewhere or if there’s a more reliable way of unlocking this phone. BTW, sprint game me MSL # and I didn’t use flashboot. but, funny thing, sprint reps did not give me MSL numbers when I called them again. The said that the sprint store’d unlock them, and the stores told me – they don’t – try Sprint…
So, to recap – rooting was successful, unlocking – was not. I still need help.

update:
I installed SuperSU, Titanium Backup, MSL utility (no need for that), GTUpdate_v3.1.8 (I don’t know if it made a difference at all), Hidden Menu (again – no need for it, I think), Virtual Terminal (that’s where I went to some hidden menus to adjust some settings*) and SSU.apk. The last apk file ACTUALLY UNLOCKED THE PHONE, and the phone no longer shows “invalid sim” or the like. The firmware on the phone was original “…MK5” (from Dec. 2013) – a must for unlocking (taken from xda-developers,com).
Therefore, all efforts and time paid off – the phone is usable over GSM network in US.
* this is what I typed in virtual terminal:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27666368378
and you’ll get an access to many useful settings. I don’t remember all setting (you’ll need to search them in XDA-developers.com forums).
I want to share this info so the other people with “former” sprint phones won’t spend a lot of time searching and searching, and searching.
I want to thank you, Max, for your videos that eventually led me to find the correct “answers”.
* this is what I typed in virtual terminal:
su
**enter**
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27666368378

“am baordc… …68378” is one command (fyi).
