im having the same issue.

The s4unlocker is saying completed and rebooting but it doesnt reboot the phone and when i reboot manually the s4 unlocker apps throws an exception. i attached a pic.

I am on NAE 4.2.2 and i have flashed MDC modem. HELP PLEASE
[Sprint Samsung Galaxy S 4 Android Development] vMAC:
So I assume no one else is having this issue?
[Sprint Samsung Galaxy S 4 Android Development] TechShui:
At least mine rebooted after the s4unlocker completed.

From what I understand s4unlocker is just a script that runs 6 or 7 QMI commands.

And this can also be done from the free version of DFS Tool. Can someone please link to original step by step instructions for accomplishing this in DFS Tool? Maybe we will have better luck doing it manually instead of this automatic script that s4unlocker uses.

Or at least we'll be able to check the DFS log for errors and figure out the problem.

[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
No. If you have NAF that means you are on Triband version of the phone and cannot unlock using this thread.

Hi

I unlocked SAMSUNG GALAXY S4 SPH-L720 with this method. Everything works HSPA+, calls, texts, outgoing MMS, its ok but Incoming MMS is not!! I can send MMS, but I cannot receive MMS. When someone send mms to me nothing happen. I dont even have a notification about MMS.

I have the correct APN, i checked this with two others cariers and the problem is still the same. I'm on stock sprint rom 4.4.2. It's about security or something?

I was using rom ROM][OFFICIAL][4.3/4.4]ParanoidAndroid and everythink is work, i can send and receive MMS. What can i do? Stock rom has some protection or something, meybe i must uninstall sprint zone? Help guys
[Sprint Samsung Galaxy S 4 Android Development] japper88:
Thanks for much for this. I was able to unlock my Sprint GS4 and use it without any issue in Hong Kong. The only thing I had to do to make the sim card work was add the APN and change the phone setting to detect GSM.

Sprint Galaxy S4 sim unlock

Worked like a charm thx
[Sprint Samsung Galaxy S 4 Android Development] rockytruelyrox:
1st to begin - Make sure you read the OP. These are the steps I followed to unlock my SPH-L720 which is by Sprint and was at Android 4.4.2 NAE firmware while I was doing it (These will not work for Sprint S4 Triband for pete's sake)

To help I have made all files needed to unlock SPH-L720 here : http://goo.gl/kp63iD

Download mode is down volume+home+power button. Then press up volume and connect USB cable. If phone is not detected in Odin then use samsung USB drivers provided in link above:

1. Put phone on download mode and flash cf root using Odin in provided package (Big thanks to chainfire).

2. Install goo.im from market and flash TWRP (ample of videos on youtube and guides on XDA for this).

3. Put phone on download mode flash the MDC modem.exe flash-able odin base in link above.

4, Put the phone in download mode and run the gs4unlock file given by autoprime in above link. Password for zip file is after _ in file name. (thanks to Autoprime)

5. If GSM network is detected successfully. Put the phone in download mode again and flash the NAE modem tar file using Odin 3.07 provided separately. Use the PHONE option for flashing only modem. Keep Reboot and F Reset time checked.

After all these steps you will have to find APN settings of your carrier and manually add apn in phone settings.

Note: I have also made the full NAE firmware in above link file name: L720VPUFNAE_L720SPTFNAE_SPR.zip
[Sprint Samsung Galaxy S 4 Android Development] parin11:
3. Flash the MF9 modem.exe flash-able odin base in link above. Is this MDC Modem or MF9
[Sprint Samsung Galaxy S 4 Android Development] rockytruelyrox:
Just run the exe without having phone connected to pc. You will know what I'm talking about. Btw am sure you have my phone number in your gmail. Feel free to reach we can have a join.me

[Sprint Samsung Galaxy S 4 Android Development] doctorman:
Thanks for the instructions.. I wish we could have update the OP to include the fact that it works with the latest NAE rom..

I am on MF9 but I have to upgrade just to avoid the annoying system update notification and then follow yours..

Q: is the L720VPUFNAE_L720SPTFNAE_SPR.zip Rooted? stock? Deknoxed? does it over right data?

does the phone have to be deknoxed?

after unlock can I remove the root and make it stock?

does this trip the knox and mess up with warranty..

Thanks again
[Sprint Samsung Galaxy S 4 Android Development] skrapmetal:
Apparently sacs latest ROM does not support GSM. Can anyone recommend a ROM that does support gsm after unlocking? Till then I have to return to stock...
[Sprint Samsung Galaxy S 4 Android Development] kennethcolman:
Does anybody know if this method works with NAF KK Baseband? doctorman says it works with NAE Thank's for any help We'll searched and found my answer sorry for jumping the gun. So here is the deal I am on NAF Baseband how do I get GSM Unlock?
[Sprint Samsung Galaxy S 4 Android Development] doctorman:
NAF is for L720T to my understanding and no it wont work on that based on what I read but again I never tried it personally

---------- Post added at 10:49 AM ---------- Previous post was at 10:46 AM ----------

for people still on MF9 there is a way to upgrade it to NAE without updating the bootloader and introducing knox.. search arround the forum if needed.. that is what I did.

I went down to stock MDL, root, unlock GSM then upgraded to MF9 then to MK2 then to NAE using the denox method.

the unlock stock all the way through.
[Sprint Samsung Galaxy S 4 Android Development] Ura535:
whether it will work on Galaxy Mega 6.3 SPH-L600 (Sprint) ? :confused:
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
No it will not.
[Sprint Samsung Galaxy S 4 Android Development] Ura535:
please tell me how can I unlock it?
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
I don't know how. I looked through google and didn't find a way to unlock it. If you're trying to use the mega overseas , I don't understand why international people do not buy international versions of the phone.
[Sprint Samsung Galaxy S 4 Android Development] Ura535:
I found a way to do it! My Galaxy Mega SPH-L600 Sprint requested NCK code!

See picture:
[Sprint Samsung Galaxy S 4 Android Development] rockytruelyrox:
I have hosted the pure stock rom from samfirmware no deknoxed or deodexed..

---------- Post added at 04:27 AM ---------- Previous post was at 04:19 AM ----------

Common Danny - some of us live in poor countries which are treated like BS when it comes to hardware & phones. 1st off the international version has inferior specs mostly CPU (Snappy Vs Exynos). Then comes the part where they are sold for ridiculous price with no contracts. For ex: S5 with exynos octa was launched for $916 in India. On other hand they get an S5 from Swappa or Ebay for $450 odd.
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
First 95% of people oversea who buy high end smart phones don't care about what type of CPU is in the phone. To them its a Galaxy S4. Look at it this way. There are hundreds of millions of people who buy cell phones. And only 5 million are registered on XDA who are crazy fanatics who root their devices.

Anyways if you are overseas and are looking to buy an international phone from the US. Buy a GSM premier device meaning a GS4 that is for T-Mobile or ATT rather than Sprint which are capable of GSM but not all the frequencies. Buying it yourself from swappa and eBay will still come out cheaper than buying it from a vendor in India , China, Mexico , Brazil, etc.

Point is if you are going to use a phone overseas for god sakes buy one that is alreadybfactory unlocked. Not a Sprint one in the hopes of being able to use it internationally. Pay the extra $50 for a GSM variant at the least.
[Sprint Samsung Galaxy S 4 Android Development] rockytruelyrox:
Sadly not even 5% of those guys would read what you said and keep bricking us. :P
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
Haha sadly that is true.

[Sprint Samsung Galaxy S 4 Android Development] daniel4653:

[Sprint Samsung Galaxy S 4 Android Development] huggiman:
My phone is in diag mode, and shows up as a port on a windows 7 pc.........though it doesn't reboot after flashed?

What could be the problem, it's obviously not being unlocked since it didn't reboot.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
I'M getting FC on the *#*#4636#*#* please advice.
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
Yes, I remember having this same issue. I saw this thread and remember dealing with it but forgot what I did to fix it. There are 2 places to set the preferred network mode.

You actually have to use this latter method and force WCDMA or the phone will only pick up EDGE for some reason (at least that's how it was for me). Setting WCDMA preferred is not enough.
[Sprint Samsung Galaxy S 4 Android Development] HeXacTa:
what rom and kernel are you using? rooted or not?

maybe your carrier's 3G signal is weak on your area?
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
No, it was a very strong signal. I'm back in the US now, but I have this screenshot.

I think it just wouldn't scan the lower frequency where WCDMA was... That was 800Mhz, and GSM was 1800Mhz or something. I traveled across the whole country and anytime I tried WCDMA preferred it worked for a bit if I had it previously set at WCDMA only, but within 30 minutes it had gone back to EDGE/GSM.
[Sprint Samsung Galaxy S 4 Android Development] Nautilusus:
Anyone getting a phone freeze and reboot when activating 'Restrict background data' ?
[Sprint Samsung Galaxy S 4 Android Development] Drumrocker:
What is the process to "Undo" this procedure if you want to lock the phone again ?. Or can anyone confirm if ##786# will wipe the unlock ?
[Sprint Samsung Galaxy S 4 Android Development] Nautilusus:
Yes..... that will wipe the unlock. Tried it myself.
[Sprint Samsung Galaxy S 4 Android Development] pmcnano:
So basically, if theres a radio update, unlock will break no?
[Sprint Samsung Galaxy S 4 Android Development] Andr3s:
Hi friend, could you explain what that is WS do not know, with any communication port works, according to me say you delete something from my phone, because when I open the program on behalf of the telephone QPST says APQ8064 (0 ). someone please tell me to do.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Stock Rom rooted with init.d support
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
no. most of the people who have unlocked have downgraded their radio to do so... and then after unlocking have upgraded their modem again... unlock sticks.

786 and radio update are not related. as its been stated.. only doing a 786 reset will remove this.
[Sprint Samsung Galaxy S 4 Android Development] raed81:
i have sprint s4 with bad esn can i unlock it and use it with t-mobile ?

thanks
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
yes, you can unlock regardless of esn.. this is completely independent of Sprint. no you can't use tmobile. the first post was very clear about that. :silly:
[Sprint Samsung Galaxy S 4 Android Development] raed81:
thanks i saw that but i was confused why its possible to test it with tmobile but not use it with tmobile
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
its possible to use a tmobile sim card(or any sim card) to see if you no longer get the invalid sim error. but if it is an att or tmo sim you will not get any signal. despite being unlocked.. Sprint has specifically blocked att/tmo on this phone.
[Sprint Samsung Galaxy S 4 Android Development] HeXacTa:
I've tried the tool with stock MDL rom and custom MF9 rom, both work well. maybe you can try another rom for it to run.
[Sprint Samsung Galaxy S 4 Android Development] xuser:
Will there ever be an ATT, T-Mobile unlock/unblock on this device via a hack? Might Sprint do an unlock/unblock after the two year contract has expired? Thanks! :D
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
Sprint will never allow it officially. it will take a hack completely separate from this to unlock. the block is restricting the MNC/MCC of ATT/TMO.. so anytime a SIM using those records is put in phone.. the device will never give a signal. it doesnt look good but you never know... :fingers-crossed:
[Sprint Samsung Galaxy S 4 Android Development] xuser:

After Sprint S4 phone sim unlocked for international GSM. .Can it still use with Sprint network?? Sim unlocked for international for travel purposed
[Sprint Samsung Galaxy S 4 Android Development] Tekone:
Thanks.. Should I activate it first or unlock it first? I'm planing to pickup one from ebay and activate with freedompop. But I travel alot to asia where they only has GSM.

How come it can't be with ATT/TMO or MetroPC etc after sim unlocked?
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
I don't think it.matters but first I would say to activate it to your sprint account then unlock it using this method. Make sure you get the SPH-L720 and not the SPH-L720T! Which is the triband version which you are not able to unlock only the SpH-L720.

For you to use the phone with T-Mobile or ATT you have to do the domestic unlock which is also found in these forums and use it domestically. I'm on ATT right now.
[Sprint Samsung Galaxy S 4 Android Development] Tekone:
Sweat.. unlocked sim on ATT but 4g LTE on ATT working? Can you switch between Sprint CDMA and ATT provider by change the configuration? Wish It can swap CDMA to GSM when some area low signal in sprint.
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
Impossible to ge ATT LTE on this phone. The phone doesn't support the bands. You can only get HSPA+ aka 4g.
[Sprint Samsung Galaxy S 4 Android Development] Tekone:
Thanks again for reply.. Can it be switch between Sprint Network and ATT Network in anytime by setting configuration ??
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
Yes. But you have to either keep the ATT Sim in the phone which means no Sprint LTE or keep the Sim with you at all times and change the mobile network.to gsm and power down the phone, take the battery out and change the Sim to the ATT one and power the phone back on.
[Sprint Samsung Galaxy S 4 Android Development] Tekone:
Haha... I'm going to using Freedompop. Don't know if they provide sim or just need my device IMEI? I using Samsung SII with freedompop in LA for just a IMEI. Hope they don't use sim, so i can keep my TMO prepaid sim in for emergency use
[Sprint Samsung Galaxy S 4 Android Development] disjes:
I'm sorry, I must have missed something but what are the 7 commands?
[Sprint Samsung Galaxy S 4 Android Development] dino_mk:
When this unlock method was first introduced, there were 7 codes u should insert manually. Now that is done by click on the button, so don't worry u haven't missed anything [emoji6]

I am unlocking the L600. Even though this thread is for the L720, I have been able to use many of the methods for unlocking the Mega. I have pretty much unlocked everything but the Sim. I am seeing Invalid Sim.

So my question here is this. For the L720 you have to use a MDC baseband, but not an MF9. How would this apply to trying this unlock on the L600? I really don't know if the L600 uses MDC or MF9 or if this is applicable at all. Any idea?
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
You cannot flash modems meant for other phones. You need older modems on the gs4 because they have the service menu needed for modifying I believe.

phone came with 4.4.2 NAE

Did as [MENTION=2245708]bond17_007[/MENTION] said and it worked.

I have no idea why i had to root and install twrp but i installed them and rooted anyway cos i have no warranty and root access is cool and a custom recovery always comes in in handy.

gsm wifi security lock everything worked(in israel) on MDC so i say if it ain't broken don't try and fix it ;)

In short: worked on mdc I can update back to nae but i see no reason too.
[Sprint Samsung Galaxy S 4 Android Development] bond17_007:
I am glad it worked. NAE is newer ROM with fixes. But if you happy with MDC its cool, you can always Upgrade to NAE without loosing the unlock. Just make sure you do not to factory reset. It will reset the unlock as well.
