I do have the international sim replacement for the note 2, but I haven't been overseas yet

I [MENTION=2684188]autoprime[/MENTION] I was wondering if the unlock would work for the note 2? If the flasher could unlock the galaxy note 2 that would be great.

I know this is off topic but it would be great for the sph-l720 threads. I can move it to Q&A. If you are intersted guys :good:
[Sprint Samsung Galaxy S 4 Android Development] AlpineMan:
Like I said, the only thing you need to do to unlock the Sprint Note 2 for overseas use is downgrade the radio to LJ1, LJC, or LK8. You do not need to run a script or anything else. Just downgrade the radio.

The Verizon Note 2 and S4's are factory unlocked for ANY GSM carrier out of the box including AT&T and TMobile. What I'd like to know is if we can use Verizon radios on Sprint phones to have a fully unlocked phone. :D

Guys, I have a problem, i ran the unlock, everything seemed to work, no longer the ' Invalid SIM' message comes up. However I get the no signal found icon, Would anyone be able to help me with this?

Here is what i do, insert a Orange (European) sim card, power the phone, switch LTE/CDMI to GSM/UMTS (select Automaic), I then get the no signal icon (next to the battery).

Thank you for any and all suggestions.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Go to settings mobile networksthen tap search for networks.
[Sprint Samsung Galaxy S 4 Android Development] jon20usa:
I have tried the above steps but am still unable to get my phone to recognize an American GSM network (with a Straight Talk SIM). If I manually search for a network, it does not find any. Does anyone have any suggestions?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
It only works on T-Mobile it doesn't work on mvnos like straight talk it only works on T-Mobile Sims postpaid and prepaid.

Also it will only work internationaly you won't get a signal domestically.
[Sprint Samsung Galaxy S 4 Android Development] jon20usa:
spydc indicated he had it working with a Net10 (AT&T) SIM (I am assuming in the U.S.). Has anyone else had luck getting this phone to work on a U.S. GSM carrier?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
I think he only got it to work in Puerto Rico but on the mainland T-Mobile only works.
[Sprint Samsung Galaxy S 4 Android Development] spydc:
Guys I know this may be hard to believe but I have phone working on (AT&T) with NET10. The NET10 sim I am using is not the t-mobile version. I don't know what else I can show you as proof.

I am in the United States.. In New Jersey.. Not Puerto Rico
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Ok I'll try it on mine that works with T-Mobile I've got a spare net 10 sim.
[Sprint Samsung Galaxy S 4 Android Development] kalda01:
Is the phone need to be rooted to perform the carrier unlock procedure ?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
No and my net 10 sim wasn't working.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Here's my fastest T-Mobile US speed test AT&T still isn't working.
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I called Sprint and they gave my phone permission to get the unlock code. I updated my phone's UICC and profile, so how do I make certain that my phone is now unlocked? Is there an app or setting that will verify the phone is unlocked?
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
Pop in a sim card.
[Sprint Samsung Galaxy S 4 Android Development] asuh:
If I pop in my UK Vodafone sim, what should I be seeing? The US doesn't have Vodafone so I can't imagine what I should be looking for.
[Sprint Samsung Galaxy S 4 Android Development] daniel4653:
Shouldn't see a "invalid sim" or "no sim card" notification
[Sprint Samsung Galaxy S 4 Android Development] raclimja:
I have a Cricket Galaxy S4 (SCH-R970C) with baseband version R970CVVUAMI3

I tried to sim unlock my phone through this method http://xdaforums.com/showthread.php?t=2283068.

I did follow all the steps but when I insert another sim (T-mobile), I got an "Invalid Sim" pop up message.

I am thinking of trying this method, but I don't know if it is safe to do so.

is there any way to back up my phone(baseband, etc...) just in case everything screwed up during this process?
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I see a circle with a line through it where the 3G/4G usually goes.
[Sprint Samsung Galaxy S 4 Android Development] zelduy:
will i loose unlock sim if there's an uprade ota from sprint? or will i still be able to upgrade ota after this unlock?
[Sprint Samsung Galaxy S 4 Android Development] zelduy:
It works!!

I unlocked the gsm.. but then I just realized that I need to root my device to edit the APN :(

is it possible for me to just edit and push build.prop with ADB instead of rooting it??

I really don't want to root this device...
[Sprint Samsung Galaxy S 4 Android Development] cramhead:
Hi

Firstly thanks for all your effort.

After downgrading my Baseband to MDC my UK Vodafone sim card is being accepted and I'm running Jellybean 4.3 build 1

I am able to make calls and RECEIVE SMS but any message I send fails.

Do I need to re-flash my baseband back to the latest one?

Is there anything else I can try?

Network mode: GSM/WCDMA Auto

sytem select: domestic and international

CDMA: NV

APNs: none

network operators: (I get the message) error while searching for network
[Sprint Samsung Galaxy S 4 Android Development] AlpineMan:
[MENTION=1312518]cramhead[/MENTION]: No. You just to update your APN settings. I posted an International APN configuration in the first few pages of this thread. It has over 1400 APN entries. Should be good for about 90% + of the world's GSM carriers.

[Sprint Samsung Galaxy S 4 Android Development] cramhead:
I've manually added the vodafone uk APN and 3G works but sending a text still fails. Could it be because I am still using the downgraded baseband?
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
I had the same issue in Costa Rica with the carrier Kolbi. I was officially unlocked through Sprint and had data and calls working, along with incoming texts. I couldn't send texts though, it would always fail. I tried the stock messaging app and third party ones. I checked the SMCC as well and it was correct. The guy working for the carrier had no clue either why it wasn't working.

My intuition was that it was still somehow stuck to Sprint and was trying to use that number for outgoing texts... My Sprint number still showed up on the status/info screen in settings rather than my local number.
[Sprint Samsung Galaxy S 4 Android Development] cramhead:
Did you ever try stock?
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
Yup, stock rooted.
[Sprint Samsung Galaxy S 4 Android Development] cramhead:
k, so I went back to stock and after unlocked again. I was able to send a SMS using my UK Vodafone.

After I re-installed I went back to slimbean 4.3 build 2 and rooted

In network settings i switched to GSM/WCDMA auto and have signal and 3g. I can make and receive calls and also receive SMS messages, but still cannot SEND ONE!

Under network operators I selected Vodafone

The Vodaphone APNs is installed (via HiAPN Global)

System select is on home/international

if I click Manage mobile plan I get a message saying "Sprint has no know provisioning website"

I'm still getting the message

"message not sent" we trying to send a sms

I've also tried sms pro with no luck

I also tried CyanogenMod but get the same problem

SAVE ME FROM STOCK! :)

So weird that stock can do it and slimbean cant

I'm stuck and need help

Anyone knows how MJA release is going to affect this?

No it did not affect my phone. I'm on 4.3 MJA

Question. Can you let us know as to which rom you used? Did you dirty flash and such?

I have the unlock and was looking to see if there is the rooted stock for 4.3.

[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
Currently the only reliable way is to odin to stock MF9 and flash the OTA. BUT it can be done dirty/without data loss and regaining root: http://xdaforums.com/showthread.php?t=2509605
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Hey guys I was wondering if anyone knows if this sim unlock works if I am on mja already? I am currently on negalite rom mja firware

Edit_

Ok so I can confirm im on negalite rom mja and I called sprint for the uicc unlock update because im going out of the country soon, and the sent me the update and it did go through, so I switched to a tmobile sim to see if it said invalid sim and it didnt say anything I went also to status settings and the tmobile icccid nunber appears, does that mean it worked for me???
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Hey man where you on stock rom or rooted? when you did the sprint uicc unlock method.. did it work????
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I am using stock that's rooted. the unlock method appears to have worked BC I popped in a foreign Sim and it didn't give me any negative feedback.
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
I know im on stock rooted negalite rom and did the ota sim unlock and tryed a tmobile sim and didnt say invalid som so im hoping it worked as well
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I wasn't trying to use domestic sim. I'm on my way to the UK to verify it worked there.
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Me either im going to guatemala in 2 weeks and I want to use a gsm sim over there so hopefully it works
[Sprint Samsung Galaxy S 4 Android Development] asuh:
Well, here in London and I can't seem to use a sim card here yet. Can't figure out what's going on. My phone still shows my US number.
[Sprint Samsung Galaxy S 4 Android Development] cramhead:
Are you sure your in GSM mode?
[Sprint Samsung Galaxy S 4 Android Development] asuh:
Yes, it's in GSM mode. I've tried going to HiAPN to figure out how to switch the APN to the Sim's provider but I don't know what I'm doing.
[Sprint Samsung Galaxy S 4 Android Development] cramhead:
if you do the xshortcut thing you'll get more options
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I've never heard of xshortcut. How does this help me with updating the APN?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Sorry guys I will no longer help with the AT&T GSM unlock as I will sell My SPH-L720 for a Nexus 4 on T-Mobile, good luck enjoy the T-Mobile unlock.
[Sprint Samsung Galaxy S 4 Android Development] asuh:
To follow up on my troubles, I was able to make it work properly with a brand new SIM. I previously tried connecting with a SIM that was a year old but apparently those SIMs won't work after 6 months and the numbers are recycled back into the pool of numbers you can use. Once I got the new SIM, it worked immediately. I am using Vodafone.
[Sprint Samsung Galaxy S 4 Android Development] dataman:
still wondering about the shortcutx
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Really? So the uicc unlock method did work for you? That's good to here, so all you do is update uicc in phone update and thats it? Any other things you do to it?

Also is it gsm where you are at? Because I believe in Guatemala its gsm signal?
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I didn't have to do anything else. just needed an active Sim card. most of the world is gsm including UK. make sure you change the phone settings to pick up gsm instead of CDMA.
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Ok so I just go to mobile networks and put gsm/umts or automatic??
[Sprint Samsung Galaxy S 4 Android Development] asuh:
I chose gsm. using automatic might work but no need to use that setting.
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Ok thanks man! Hopefully all goes well, I will uppity the uicc one more time before leaving the country tho, just in case lol
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
So... I had used this method to unlock my phone when I went to the Philippines. Now that I'm back, I really want to leave sprint. I've heard people successfully unlocked the phones for domestic usa use on T-Mobile. My question is, will 4g lte on T-Mobile work or well it only be h+. Thanks so much for the feedback
[Sprint Samsung Galaxy S 4 Android Development] asuh:
You should be good as long as it went through. Expect that HSPA+ signals will be closer to 2G speeds sadly. Using Vodafone in the UK, I've been experiencing poor data speeds everywhere I've been. Feels like I'm using an old dial-up modem sometimes, and won't even download at other times. :-/ Wonder if I should try O2 or other providers...
[Sprint Samsung Galaxy S 4 Android Development] jarcher12:
how screwed am i

i live in Indonesia and bought a samsung s4 sprint cdma/gsm tried the unlock thing and lost all signal. how acrewed am i and is there any way to get the phone to connect to the network again. ? or did i just make a very expensive paperweight?
[Sprint Samsung Galaxy S 4 Android Development] hayat4:
I've been reading through all this like crazy. So let me just ask ... is there a way to get ATT to work on SPH-L720 if the phone has never been activated by sprint? or even T-Mobile?
[Sprint Samsung Galaxy S 4 Android Development] dataman:
No to ATT

Tmobile prepaid works not sure about other tmobile
[Sprint Samsung Galaxy S 4 Android Development] jap_line:
do i need to downgrade or is it possible to unlock L720 4.3 MJA version?

can i just flash the modem to MDC or i need to flash the full 4.2 MDC firmware?

i already tried to unlock, it reboots and says success but the phone is still locked.

:confused:

need some help and idea here
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
I've gotten T-Mobile prepaid and postpaid to work see my post with instructions about 40 or so pages back maybe less it includes screen shoots I haven't got ATT to work and I'm using T-Mobile on my Nexus 4 so I can't help with that good luck.
[Sprint Samsung Galaxy S 4 Android Development] cris_epic:
Is your 4g working on t mobile???
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Yes I had HSPA + 14.4 on T-Mobile see my post with instructions 30 or more pages back.
[Sprint Samsung Galaxy S 4 Android Development] jap_line:
update about L720 4.3 MJA.

i tried flashing 4.2 MDC or lower modem yesterda but it fails.

also tried flashing full rom MDC Stock recover.exe but still same, end up failed and now phone stuck in download mode.

i guess i need to go back in 4.3 MJA now to get back to normal.

im still looking forward to unlock this phone hope i will success in my second try later.

[Sprint Samsung Galaxy S 4 Android Development] fergdizzle9090:
i have been reading through this and im a bit confused. i know i need to international unlock first but it seems my sprint s4 can be used on tmobiles network and is able to get data correct? I am rooted and on MDL, will that work and also do i need to be on stock rom? is there anywhere that has a set guide on how to unlock domestic gsm with data? its just a bit confusing and difficult to follow a bunch of posts here and there. im specifically trying to get on tmobile.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Yes I got it working 10 to 20 post back MDC MDL and MF9 modems only. With data working it's only HSPA + on 1900 MHz up to 14.4 mbs and EDGE no luck on AT&T.
[Sprint Samsung Galaxy S 4 Android Development] fergdizzle9090:
alright so i can stay on mdl after i get it working so i dont have to upgrade and get knox? and that seems like pretty good speeds on tmobile correct? i am looking for tmobile to work specifically and i have a sim, i guess ill try and find that post. i have to do the international unlock on page 1 first right? and then do your guide back in the thread?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Yes stay on mdl the speeds are good. Yes do the international unlock first. Then my unlock.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Here is another screen shot.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
One more of multiple T-Mobile HSPA+ Speedtest.
[Sprint Samsung Galaxy S 4 Android Development] fergdizzle9090:
awesome thanks i really appreciate it. should i go back to stock or you think aosp will be ok? also how should i check to make sure all the unlocks work? ill try and figure this out and see if i can do it without bricking my s4 lol
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Yeah no problem I'm on the T-Mobile $30 plan with 100 minutes unlimited text and data 5GB high speed and loving it on my phone.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Has anyone gotten this to work with GSM MetroPCS? They have the same unlimited plan as T-Mobile but for 10 dollars cheaper. AFAIK they use T-Mobile for their GSM network now since T-Mobile bought them. If so, did you get everything to work? Voice/Data/SMS/MMS?

---------- Post added at 08:16 AM ---------- Previous post was at 07:41 AM ----------

Once you had everything unlocked and all that, did you just plug in the SIM? Or did you have to change APN settings and what not?
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
This is what I'm getting in the second unlock menu.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
No I haven't used Metro but I've used T-Mobile so Metro should work after you do both unlocks use a APN app to add the T-Mobile APN yes I got everything working.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Thanks, any idea on the screenshot I posted?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try this dialer code *#27663368378# instead of *#0011# if it doesn't work reboot and try again.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
That new dialer code doesn't open anything up.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Reboot then try the original code if not try a stock ROM then try both codes.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Does the same exact thing on stock MF9. First menu shows the same thing, No service. Second menu doesn't even come up.

EDIT: Ok I got it to come up another funky way. I've changed all the things in the pictures. Are there any other things I have to change? Like in mobile networks or something?
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
What happens between the 4th and 5th screenshot?

EDIT: With my Pre-paid T-Mobile SIM in, the only network I can find is Rogers Wireless from Canada. I'm definitely not in Canada though....

EDIT 2 : Now it's finding other random Canadian Cell phone companies... Any Ideas? Like is there some international roaming only option that I'm not seeing?
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
What way is that? I have the same as your screenshot.

Stock MF9 rom/modem.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
When it says no service press menu, back, menu, key input. Type 1 then press ok. Wait 6 seconds and then menu, back again. That'll bring you to the main menu.
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
I saw that elsewhere, but it still leaves me at "No Service". I'll try a different SIM card, that might be the problem.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
If I can figure it out I'll definitely help you out!
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Closer....

CLOSER STILL! !!!
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try select automatically.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
I don't understand why I'm connected to tmobile but in my notifications it says "selected network t-mobile not available."
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try select automatically and that should go away. I don't know specifics of what went on in the hidden menu one day I way super upset with Sprint and decided not to sleep untill I got my phone unlocked for T-Mobile.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
That error is gone, but now I'm still just getting edge. And cant call or text either.
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
Different SIM didn't change things.

I've flashed stock MF9 everything, I do *#0011# and it takes me to no service. Nothing changes when I do menu, (select back from the list) etc.

I put it to GSM Mode in network and info was updating, but nothing like spydc said in post 348 about UMTS Main Menu.

I'll happily change roms for this, just point me in the right direction.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try a AOSP rom like cm 10.2 or alpha cm 11 or a google play edition rom I've had better luck with the google play edition rom the 4.2.2 one and everything was working if not try sacs custom rom both of those have given me the best performance after following my unlock.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Do you have to do it all over again once you flash a new rom?

I'll be sure to try that and report back!
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
OK please do.
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
I eventually got passed the "No Service" *#0011# by 1) being on GSM and not CDMA when I started, 2) doing "Select" instead of "Key Input" after pressing "Menu", though I've had to alternate which one I use since it randomly changes the one I need to use.

Now I've done everything listed, (SW/HW WATCHDOG does not indicate any change when pressing them 6 times) and when I get to Switching to GMS/Manual Network no networks come up.

This is a TMobile nano sim in an adapter (home made, though all sim info is readable). It has not been activated. Is this sim the reason that I'm not showing any networks?
