SimLock Solution For All 4.3 users

Hello to you all
I would like to show all of you 4.3 users the solution "elvisypi" gave me in my private mail and finally i succeed to unlock my device.
So all of us know that sprint or google changed the way HtcOMADM works and we can't use the original system for unlocking our device.
So here is the solution that "elvisypi" gave me :
1. Download the "Stock with goodies 4.3 ROM". Don't flash it wet. (link : http://www.mediafire.com/?9y21d2wlszh6d6c )
2, With an archive viewer like winzip open the ROM.zip and go to /system/app
3. replace 2 apps which I have attached: HtcOMADM_SettingsPlugin_SPCS.apk and HtcOMADM_SPCS.apk. Just drag and drop and replace.
4. Finally flash the ROM.
5. Install the HTCOneSIMUnlockHelper and follow the onscreen instructions.
This system works 100% and this way you can be on 4.3 rom and still have an unlock GSM sprint device.
again , many thanks to "elvisypi" for his great support

sim unlock
Hope it does
downloading....

Would this work with other ROMs like insercoin?

You must use a stock rom for this to work

Hey, are you using this with Tmobile or another service?

I'm not using t-mobile , I'm not from the US but it should work with any GSM sim after the unlock is done

I've followed your directions, using the ROM you provided (only difference being flashing the root-fix) and I get vDM errors every time I boot and the app says it's unlocked but my Tmobile SIM gets no signal. Is there any other way i can check if my phone's unlocked?

Yes I have, it says preparing SIM card but I never get any bars. I read in another thread that I need to be on an older radio in order for Tmobile to work. And for that I'll need s-off which I can't. Sigh.

Flash the release radio and let us know, I'm interested in using an At&t card for when I need a good data connection.

It didnt work for me?
I did exactly what you said an When the phone starts up it says unfortunately ui has stop working an it keeps popping up an i cant do anything with my phone

Thank you for this already pressed the Thank you button also
i was getting annoyed that i couldnt find the files before i found this thread

HTC ONE
I did everthing s-off....flashed to the old radio baseband....tried everything still havent got any signal....who know what a problem?
The only thing is that I've flashed my sprint htc one to the Straight talk. Could it cause a problem?

I am also trying to unlock for T-Mobile. Running into the same issues as others. I was reading a thread where someone was apparently using it on T-Mobile, and PMed them on how exactly they did it but never got a response.
Would love to hear if anyone has it working on T-Mobile

This works. :victory:
Only need to extract, modify and zip again.
Flash with TWRP.
And everything is working normally, no need to reinstall or root, or whatever.
The only problem is that every time I turn on the phone, I get the error message VDM, but it disappears instantly, without stopping or forcing any application.
I live outside the U.S., and continues to operate all perfect with SIMUnlockerHelper. :fingers-crossed:
My device: Sprint Htc one = Unlockboot, TWRP, SIMUnlocker Helper, Root, and the rom on the top of the post. (benny's 4.3 LOL)

it actually works, but if you're using a sense rom I think you only need to download the apps in the op and replacing in system/app
I did this with insertcoin 6.0-4, the unlock helper app didn't recognize the rom, but with the terminal emulator method it worked just fine, tried with a sim and all fine ... then put again the original apks and you don't have to deal with any error popups

Interesting. I was under the impression that our version of this device did not support domestic (only international) GSM bands, hardware wise.
Is this version of sim unlocking different than what you would get if you asked Sprint? (they do allow you to unlock it if you meet certain criteria, like good account standing)

it supports the bands, but all the radios except the original one block domestic gsm carriers. if you still unlock and use that radio, it'll work.

Not working
I tried everything mentioned above, ( Unlock bootloader, S-OFF, Root) also changed the 2 apps in the system for the 4.3 ROM Stock rooted deodexed and then used the SIM unlock helper.
Then Got the same result : No GSM signal, and the SPRINT logo still on the top when I make a call, the same answer comes: " Error number 16 script 3."
I'm using Straight Talk Sim by ATT.

[HOWTO] / [GUIDE] SPH-L720 Domestic SIM Unlock T-Mobile:AT&T:metroPCS:Straighttalk

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

Nice. Will it work with t-mobile in Los Angeles?

Np Man, and good catch, fixed. I'll check out that step 8/9 and fix accordingly.

Thank you so very much. I believe opening up the bands made the difference, but I'm now connected to T-Mobile.

Most excellent! If you fiddle with acquisition order and make it gsm_umts it might identify your network type correctly.

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

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

Thank you very much, imbmiller.
I will just wait patiently for the MJA solutions before upgrading to MJA/root/unlock.

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

You can use MF9, MDL and MDC for the domestic unlock.

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

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

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

Someone on this thread got it to work. I'm unsure if Att has hspa+ tho so you might be relegated to edge

Nevermind, it works on Metro it just matters the SIM http://forum.xda-developers.com/showpost.php?p=47624568&postcount=568

Did you install hiapn and add the apn? What baseband are you on? What rom and kernel? I'm not super positive about mvno s but I'd probly go back to the beginning and start over.

Sorry I had to edit my post. It did work. There are two different GSM SIMs the one with the dot seemed to work. I Got Edge, 3G, and H+. It is awesome. I also still have 3G with Sprint with the SIM in. I got two phones in one. Thanks.

So I've been on T-Mobile for the last 24 hours but my HSPA+ signal is weak and slow (under 1mb), while my co-worker on T-Mobile (and a T-Mobile phone) has full HSPA+ signal and speed (5-9mb).
Any thoughts on what could be the cause?
I'm running CM11 on MDC. I'll try some other combinations tonight to see if things change.

[Q] Rooting N900A to Lollipop while using T-mobile.

Ugh, I am having so many issues with this at the moment. One of those things being that I am using T-mobile as my carrier. I'm stuck on 4.4 at the moment, and need to update it. But, will that relock the phone? How do I re-unlock it if that happens? I've already read that I can't flash the phone to T-mobile ROM, but are there any custom ROMs that you would recommend [I do actually use the S-pen, not sure if any have been updated to where that can still be used.] Lastly, is there any way to get mobile hotspot and tethering to work now that I am using tmobile?

http://forum.xda-developers.com/note-3-att/general/t-mobile-alliance-rom-att-note-3-t3065127 I don't think you would have to worry about any of this as you are using T-Mobile " After the phone came up, I went to settings..general..applications...running .... and found every Tmobile app and cleared cache and disabled them. The real important one here is the Visual Voicemail. Otherwise it will keep on trying to contact Tmobile and then you will get text messages saying there is an error. Thanks @sapps
Wifi Calling is throwing a sim card error (as you would expect). Only problem is it is shown in status bar and lockscreen. I'm sure there is a way to hide it or disable it. I just haven't had a chance to figure it out."

But it's the N900A, so it's the AT&T version. Won't that brick the phone if I put the tmobile ROM on it? That's what I've read in other threads on here anyway. [Honestly I shouldn't write when I'm tired, or I would have explained this better.]. Basically, I bought an unlocked AT&T phone. A Note 3 to be exact. It's stuck on 4.4 but can upgrade to lolipop. Nothing I try will let me upgrade the normal way. I'm not sure how to upgrade it without relocking the SIM card somehow. Or is the simcard already semi-locked and that's why it's giving me the error? I also can't even find a AT&T specific rooting guide for this phone. I saw every other carrier except AT&T, does that even make a difference? And are there any ROMs that can return S-pen programs after I install them, or should I just stop at rooting if I want that? If so, I just really want to upgrade to lollipop and root the phone. I would like my mobile hotspot and wifi calling to work, but I suppose I can make do with hangouts.

It won't brick you phone. It's a T-Mobile Rom that's been ported for AT&T Note 3. After you flash the Rom, you have to Odin the N900A_OC1_ALL_Other_Stock_Partitions.tar.md5 using Odin's PDA slot. As far as rooting what you have now, just use Towel root https://towelroot.com/ (install on phone like any other app) and click "make it rain". Install Supersu, busybox and Safestrap. OR use Kingo Root http://www.kingoapp.com/ (Kingo Root will install supersu for you). The reason it won't upgrade to Lollipop is you have a T-Mobile sim card in it. It needs a AT&T sim card (I have AT&T and can't upgrade mine unless the sim card is in the phone). If you just want a rooted Lollipop Rom, but it's AT&T http://forum.xda-developers.com/showpost.php?p=59666958&postcount=2 You know since you're on T-Mobile you have to go into settings>more networks>mobile networks>access point names and change it to T-Mobile's APN. I would just root it and put the T-Mobile Alliance Lollipop Rom on ATT Note 3 on it. I gave it a try yesterday and it does have T-Mobile apps on it, just not for me. Just remember to change the APN to T-Mobile's ( just write down the one you using now).

You Need to start out on either NE3 or NH3. Downgrade now if you need to. Just remember when downgrading don't flash bootloader. This needs Odin and root to succede. Now That thats out of the way you need to download some files to deal with later on.
MF1 Odin flashable
regionlockaway go to the second post and download the apk to install on your phone.
this method uses an old method in a new way.
here is the guide
1. install regionlockaway and reboot to download mode
2. Flash modem.bin with odin in download mode
3.reboot to system and use regionlockaway. follow the instructions in the app.
4. profit?
As far as my understanding after you do this you can update your modem without it reverting back to being locked. I am running oc7 modem on a T-Mobile MVNO without issues( if you want aws unlock you are going to have to use this then the appropriate modem for that and not allow for the modem to update when updating to oc7 by modifying the oc7 installer and removing the modem from it)

I am ready... I have been reading for days about sim unlocking on 4.4 and up..I finally coined up $25 for a code but takes up to 5 days, 2 days ago. my next attempts were going to be with my paid copy of CDMA WS. Either way it is just to experiment with and would love to gain the knowledge. I have a couple different carrier sims ready to go. I would love to give it a shot.....

hey guys i have created an easy sim unlock that should work for 4.4.2 and for 5.0.1
for the 5.0.1 sim unlock you have to do it on 4.4.2 and flash a modified partitions file to upgrade to 5.0.1 while keeping sim unlock.
if you guys are interested in it let me know and i will set up a few beta testers for it. i cant say for certain that it works because i dont have a non ATT sim card to test it with.but it should work. it should also allow you to enable aws for those on T-Mobile by following a secondary guide.
let me know and i will start having people beta test. i only need between 1 and 5 testers

ok ill pm you with a guide once i have it written up.
EDIT: it should be in your inbox

i was able to test a verizon lte sim and it didnt give me any issues. it regestered the number in the status. so i belive it worked. i would like some more testers to get information about it. i need more testers before i feel ok giving out the method.

Been sooo busy!!!! K, thank you for the guide. I haven't been able to try anything except a Verizon Lte sim. It registers the number and the network lock is gone. However I don't believe we will get data service with a Verizon sim as I don't believe the hardware is capable?...I wasnt able to place a call as I got" Emergency calls only", all I did was swap sims, occasionally I have to call Verizon and have them add the new phone to the plan before it will work and I didn't do that yet. Will try a different carrier sim tonight.

so before you did the guide did it give you issues with the verizon sim? and now it dosent?

It did give me issues before flashing the mf1 and after the flash and region away no nagging about sim unlock code! Havent gone any further yet. I will report back after using a different carrier sim besides verizon that is.....I think it works....

sweet thank you for the feedback man. i did the 5.0.1 upgrade method i detailed in the PM after i finished doing the unlock on my phone and it worked the same as what you described (i only had access to vzw lte sim also) so i belive i made the update file correctly also. im not really getting any bites on more testers so if it pans out well for you i will polish up my guide and post it here to have people test it instead of making them PM me.
thanks again for being my beta tester. if we get this working well we can save alot of people alot of money
ps for voice and sms verizon lte sims are useless because they still use CDMA for those features

Finally put in another sim...Put in a Tomb sim and no nagging about unlock code, I got "Sim not provisioned" as it isn't active at the moment. So I'm thinking it worked. Thank you. I was thinking I'd get voice and edge speeds with a Verizon sim in this phone, (utilizing GSM bands), in my area anyway, but maybe I'm mistaken. I'll post again after using another carrier's sim.....

I did as instructed and according to flashfire at the end of flashing, it said it was successful and it rebooted (so far) to the lollipop boot animation and am awaiting for it to get past the at&t logo screen. Its at least gotten a lot further than all my earlier attempts...I am assuming its taking a little while for its initial setup of OC6....
more later on its success or failure....
well it was a partial success....it flash and booted into OC6 but sim card is not recognized, no baseband.....now installing updated version of flashfire....should i now flash the MF1 modem again via flashfire?
well i went ahead and did just that flashed the mf1 modem via flashfire and all is up and running successfully (FINALLY!!) with root on deodexed rom OC6...
Kudos and thanks goes out to ya!

Never mind. The downloads on dev-host work from my computer but not from tablet or phone.

odin ne3
flash mf1 modem with flash fire
make sure you are rooted and have busybox
use region lock away. try with att sim in phone.

Trying to do this for my s4a but flashfire is being uncooperative, it just crashes any chance it gets. Any other flash apps this will work with?
Edit: do I need safestrap for FlashFire?
Edit2: Fixed the issue with flashfire, If anyone runs into this issue you need to flash stock NE3, and re-root.
Rest of tutorial went perfectly. Cannot test unlock status atm, but no errors.
Thanks Matteo, you're a top lad.

Will this same method work with a deodexed OC7 ROM? I only ask because of the I537_OC6_Stock_Partitions_mod_sim.zip - not sure if this still works the same for OC7. Just to clarify, do you know if region lockaway is necessary to get T-Mobile AWS/HSPA bands? I've got a working cell and LTE connection without doing any of this, so I really only needed to do what's necessary to get those bands (which I think the old modem will help enable).
Thanks for the assistance!

[GUIDE] AWS Unlock for i537 I537UCUBML2 (4.3)
read the posts to make it work
also check out this post if you have issues with getting qpst to work. dont follow the whole post just qpst part http://forum.xda-developers.com/showpost.php?p=56023258&postcount=68
then follow the guide i posted in my last edit to keep the aws unlocked modem while on 0C7
edit:
you can use the oc7 deodexed rom. you just have to remove the modem from the rom file useing winrar or 7zip. also you have to remove it from the updater script useing a text editor. drag it out of winrar edit it and then drag it back into winrar. that way if you flash in this order you will be fine
partitions mod file
oc7 deodexed rom.
that way you keep the modem
from when you installed and unlocked mf1 modem on 4.4.2

[INFO][HOW TO] Sprint Galaxy S4 Sim Unlock (SPH-L720/jfltespr) ATT/TMOBILE

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

I didn't know you had anything to do with it, me an auto got my s4 unlocked on irc before that post, even before his original international unlock post. Maybe you told him how and he just didn't inform me.

Maybe I was a little late, I barely figured it out in the international unlock thread and put my findings their. No worries again thanks for making this more clear for others.

I added you to the thanks, even if you didn't originally find it, you have helped others get there and that should be recognized.
