Domestic unlocked worked now doesn't

Hi,

I did the domestic unlock about a month ago. my tmoible sim card worked fine. put on CM11, everything worked fine, calls text data. Got a new tmobile sim card put it in the phone, and wrapped phone up for daughter for xmas. activated sim on xmas, worked fine till the next day. now when make a call it says account cannot be validated call customer service., cant send or receive texts or data.

CM11 doesn't have a service menu.... so cant check. apn settings are all Tmobile and correct.... calling TMO customer service they say sim is active.... but cant see the imie number on their end... and says they cant help me since it's a sprint phone....

I'm guessing odin back on the the orginal rom on this thread, and try unlock again.

buy why would it work unlocked fine, but then stop working....

thanks,

im having trouble with the L720T also far as getting it in the right service mode can anybody help
[Sprint Samsung Galaxy S 4 General] es0tericcha0s:
Make sure you are using the MK5 modem and are rooted then just use the Galaxy Tools app to get access to the TestMode in the IOHIDDENMENU found in Galaxy Tools. Just follow the rest of the guide from there.
[Sprint Samsung Galaxy S 4 General] Mrhunter13:
I got it to work just could not get it to go to the correct service mode screen
[Sprint Samsung Galaxy S 4 General] es0tericcha0s:
:confused: How did you get it to work without getting into the correct service mode? And next time you need to, just follow that method as it's crazy easy and way less glitchy than the dial code methods.
[Sprint Samsung Galaxy S 4 General] Mrhunter13:
I don't the unlock on the L720 just not the l720t until last week ..I had to do ##0011# then Q then 0000 to get in to the service mode that it should be in
[Sprint Samsung Galaxy S 4 General] StifflerServices:
when you say "Reboot the phone manually:manually:manually IMMEDIATELY" are you just emphasizing to reboot manually ONCE or actually 3 times right after the 6th press on HW WATCHDOG and to do this with the power button with the Reboot options like normal? Sorry if this is seems stupid NEWB question, just want to make sure not to take the importance literally and the wrong way. Also If I want to Domestic unlock the device but don't have a need to use another carrier just yet as I still have a contract with sprint, will this allow me to switch my device to use gsm or cdma towers without changing sim in low sprint signal areas, sorta like changing the PRL? TIA
[Sprint Samsung Galaxy S 4 General] :
I followed the steps and was able to get edge speed on AT&T. I upgraded the modem to the latest and I still have edge speed. Any thoughts on why I cant get H+ speed?

I have the network set to gsm only because its the only setting that gets service and I have the correct APN settings for HPSA+

I did notice on step 6 SIM Class Control I cant change it to UMTS setting.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
The reason you can't get HSPA is because that is a WCDMA technology and you have it set to GSM only. It should get signal fine if you set it to WCDMA All in the service menu, which will make the network mode show as WCDMA Preferred. That's assuming ATT has HSPA+ in your area, of course...

In regards to the SIM Class Control, if tapping UMTS makes it show GSM, then tapping GSM should make it show UMTS. I've seen it happen before.
[Sprint Samsung Galaxy S 4 General] :
I confirmed ATT does have HSPA+ in our area. I set it to WCDMA ALL in the service menu and you were right on SIM Class Control, I taped GSM and it changed to UMTS. I let the phone sit on WCDMA for while but no service showed up. I went through the steps again just in case with still no luck.

**UPDATE: HSPA+ just popped out. I left it sitting there on wcdma and no service and bamn all of sudden i have service. so far it has not disconnected. thanks iBowToAndroid!!!

No signal when on 3g

Updated the modem from mdc to ng2 but i keep having the same problem, in some areas I get pretty good signal, and pretty good speeds H+, but keeps on switching to 3g and then I get no signal at all even with full bars.

Great Work

First great work and this has been working excellent for me for about a week now. I did read a lot of this thread, not all 138 pages that appear now, but at least skimmed over 80 of them. I see different posts that say you can try custom ROMs and it shouldn't be a problem, but then again I see that people are having some issues when they use custom ROMs. My question is would I be able to use custom Roms from the At&t S4 development thread or would I need to only use Sprint s4 custom ROMS.......or dare I say......both should worK?

I am using a At&t Straight Talk Sim card and after unlocking the phone and putting my Sim card in, getting booted up, my phone updated to NG2 modem. Will that affect anything?

I do apologize if I'm asking something that has been answered but I did read a lot of this thread and still wasn't sure enough until I felt like a question would be better. My Android experience has been with At&t devices and this guide really helped in a big way. Once again thanks. Can't buy you a bee..........make a donation right now, but I will very soon in the future. :D
[Sprint Samsung Galaxy S 4 General] acipon:
Works for text, need help with calls.

I followed all of the steps and it is working well except a thing or two. So far I can text from my GS4 after the sim card is in and the data is working quite well. However, when I make and receive calls things get a bit goofy. When a call is initiated from the dial pad, the screen becomes blank white for 30 seconds and does not show the status that the call is made. There are no buttons for hanging up and the phone does not allow voice to transfer from the phone call.

I assume that the T-Mobile network is working well, but hoping it is just a simple phone setting.

Great read and very helpful so far, If anyone can help with this last issue I would be very grateful. Please help

Haven't tried to flash it to a different ROM, it should stick, at least that's what I read on previous posts.

Give it a try and let us know!

I kept getting force closes when i tried loading virgin rom (a tmobile kit kat rom).

I just flashed back to the nandroid of the sprint rom.

I also sold the phone (as I had a buyer who could only buy it in tmobile).

How is the reception for those of you who are using TMobile on the Sprint S4?

I'm using Metro PCS and the reception is pretty bad.... I'm glad it's working, but just wondering if worst than normal reception is expected.

[Sprint Samsung Galaxy S 4 General] imbmiller:
Technically I think that the international unlock one click didn't work for you... I'd say do whatever you did, but in reverse.

Does anyone know - is it possible to flash a TMobile modem on to the Sprint S4 and then have access to 1700/2100 band?

I'm not sure if the Sprint hardware is actually different and the modem software is what's prohibiting other bands..

help me please

bro i try to do this but in odin showme a message "pit partion failery" can u send me u pit partition
[Sprint Samsung Galaxy S 4 General] imbmiller:
I wouldn't advise doing this. Even if they were identical chipsets, which they aren't, you could brick your phone easily and the only way back would be to JTAG the correct modem images.
[Sprint Samsung Galaxy S 4 General] imbmiller:
If you can find a way to downgrade it'll work great. Don't fear, i'm sure a downgrade is eminent.

I've never seen this error but chances are you are having driver problems related to the international unlock 1 click. I doubt anyone else's partition will help you though, read through the thread on the International unlock for troubleshooting.

Mine worked if there is no sim inserted you will get the circle with the line through.. and if the sim card is damaged it will also not function i first tested with old tmobile then when process was completed went to shop and tried simple mobile i do not think it is unlocked through cdma becuase i ttied to use it with voyager mobile sprints mvno and they said it was refused.. by sprints own system.

now my next step is to choose a prepaid plan and the toss up is between walmarts family plan and straight talk.and the best thing is i can choose between att and tmobile muahaa gotta do more research for frequemcy tho

Thanks so much for the help guys couldnt do it without the help of the guides...
[Sprint Samsung Galaxy S 4 General] imbmiller:
I would (and have a billion times) go back to the beginning and do EXACTLY what the guide says. This recipe works, I don't know anything about the infinite amount of alternative recipes.

A little update: I was able to access Voice Mail settings, after I changed the Straight Talk T-Mobile compatible SIM with an Straight Talk ATT compatible SIM, and VM works.

"In About Device - Status it sees my phone# like this: 000-000-0016"

Solution: ##MSL# (MSL=your MSL 6 digit code) and you have access to MDN and MSID. Edited both fields with my 10 digit phone no.(phone restarts) and now my number is showed in phone About Device - Status.

Keep up the good work! :good:
[Sprint Samsung Galaxy S 4 General] fyrusher:
Thanks OP for this unlock. I got the L720 unlocked. But something is strange that if insert the PTEL sim (T-mobile network), My phone shows T-Mobile logo. all of my other androids will detect as "PTEL Mobile". If input the " PTEL" APN setting and data is not working at all. the only option use "T-mobile" APN setting and my data (HSPA+) is working . FYI, my other androids with PTEL sim must be with "PTEL" APN.
[Sprint Samsung Galaxy S 4 General] es0tericcha0s:
Just one of those inconsistencies you have when not using an actual GSM phone. My Cricket card always shows as ATT on Sprint phones. Not usually a big deal, just aesthetics.

So many hours, no joy (or service menu)

Alright guys, by no means a noob, in fact this has got to be the first time I'm asking for help because I'm stuck. Hopefully one of you guys can Help me.

Sprint S4 720 on NG2

Skipped step 1 and used SSU for the international unlock.

Downgraded just the modem to MF9 at first and later to MDC just to see if it made a difference.

Eventually Odined Stock Ng2, re-rooted and downgraded again just in case.

No matter what *#0011# brings me to a screen that says "Service mode" and has some stats.

Using Galaxy Tools and tapping the 3rd option "testmode Menu" Brings a screen that says ServiceMode and under "debug Screen" Then 1 Basic Info 2. NAS info 3. AS Info 4 GPRS Info 5. SIM Info

Pressing the left menu and imputing 1 or 2 or q or 0000 does nothing.

After many tries I've switch /efs/carrier/hiddenmenu to "on: and nothing.

I CAN NOT ACCESS THE REQUIRED MENU

Where I stand now after many hours of trying and reading pages:

I played with the "LTE mode Menu" of IOTHiddenMenu out of desperation, for some reason after doing that I don't get the invalid SIM message

Since Invalid Sim mesg was gone, I went to the Network settings and created my Tmobile APN settings, placed Network mode in CDMA only and turned off Roaming guards.

After doing this the phone shows full bars and a 3G icon. The phone doesn't actually make/receive calls and net does not work.

Been at this for too long and about to cry, hope someone here has the answer. TIA!
[Sprint Samsung Galaxy S 4 General] Crossvxm:
lol don't cry yet. If I remember correctly, that menu is accessible on the MF9 modem, which is why it is required to downgrade. Sometimes when you try to access it, it takes a while to pop up. Especially after a fresh boot. Let everything settle, try accessing it on MF9 modem and give it a minute or two. If it doesn't pop up, report back here.
[Sprint Samsung Galaxy S 4 General] blackshadowed:
Thank you. I read about the slow response of the menu on other pages and did play the waiting game on both MF9 and MDC and no success. Right now I'm just waiting for one of you geniuses to come up with some unorthodox idea to save this project lol.

While waiting for you guys I updated the modem back to NG2 just for giggles and tried making a call. The line rings about 6 times and then a voice says "your account is not authorized to make calls to this number. For additional authorization, please contact customer service"

I am using a fully activated SIM from my Tmo Note 4.
[Sprint Samsung Galaxy S 4 General] Crossvxm:
My biggest advice is to start all over. Flash the full stock via Odin. Next, flash the necessary modem. Then try again. It worked for me without issue on MDC. You should get a menu that is black and pretty much looks blank. That's the menu you need. But as I said, since you've already flashed all sorts of things, flash back to FULL stock as something may have jammed along the way. Also, confirm the modem flashed by going to settings, About Phone and somewhere there you should see MF9 (I think under baseband)
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
The unlock can be performed on any software version, and any modem version. ZERO downgrading required. Root not required. Very easy.

1. SSU

2. Do the required service menu steps

Just have to know the dialer code for the service menu
[Sprint Samsung Galaxy S 4 General] SPHM900:
so no matter what i do i cant get anything to flash. using odin 1.8 and have a sprint GS4 rooted, flashed back to stock with bootloader and recov multiple times. i cannot get any lower modems or firmwares to stick after MK9(?) which means i cant get my sim unlocked L :( please helP!!! i kinda know what im doing but wtf am i doing wrong?! even rwilco12's AUTO FLASHES dont work??!!! so yeh....thats kinda where im at....currently have JFLTE offical 5.0 running, but its useless since i have tmobile and not sprint. **** I EVEN TRIED FLASHING TMOBILE MODEMS AND BOOTLOADERS AND FIRMWARES!!!! nothing flashed. it all failed. but i dont think it would of done anything anyway. tried flashing the 5.0 JFLTE from tmobile, and currently is whats on my phone. soo little help? im stuck. ive tried flashing MIILLIONS of times, maybe i have to go ADB? idk... i dont know any command stuff...

hahaha i have the note 4 as well. tmo should of sent u a SIM that has free data for life!!! u get 1G 4g then the rest 2g. thats what i plan to use in my S4 as it is going to be my cars GPS system :)

if someone steals my car that is...
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
Jesus Christ, dude.

1. Chill.

2. Read the thread. Ignore the OP - it's outdated.
[Sprint Samsung Galaxy S 4 General] ecs87:
Your version of Odin is outdated. Way outdated. I think the current one is 3.10. And I would keep from flashing any kind of different firmware from different carriers at this point. Samsung likes to create boobie traps that will soft brick your device should you load the wrong thing through Odin.

For what it's worth, load the latest kit Kat firmware version for your device. And by firmware I don't mean custom ROM. I mean the entire 1-2gb package from sammobile. Unlock with ssu. Unlock with service menu. Win at life. Don't use custom ROMs if you want to/currently have baseband/modem hacks.
[Sprint Samsung Galaxy S 4 General] huffington:
Thanks in advance

Sorry if this is overly simplistic question but unsure do to the sheer volume of content here.

Can I,

1) Carrier Unlock Sprint SPH-L720 Galaxy S4 to use Domestically on TMobile or another carrier?

Was not able get past step 4.

Thanks for any response!
[Sprint Samsung Galaxy S 4 General] es0tericcha0s:
Yes, as been mentioned many times already. Here's the trick :

Dial *#0011#

Hit Menu button and select Back (not the actual back button, the option in the menu that pops up)

Then Menu and enter "Q"

Then Menu and enter "0000"

Wait about 5 - 10 seconds and viola!

For some reason, hitting the Back option first really helps before you enter Q and 0000. Just unlocked 3 different S4s past 2 days using that method.
[Sprint Samsung Galaxy S 4 General] ecs87:
Don't know how anyone hasn't noticed it yet but you don't need four zeros. All you need is one...unless you're an overachiever ;)

Disconnect from Sprint?

I tried this and was unable to connect to Sprint any longer. Although I didn't add a new APN - since I figured the old one I was using for Sprint should still work. I did the following based on a post I didn't record:

Select CDMA, then 1.COMMON, press next page until page three of COMMON and select 8.PREF MODE SET and selet GSM_WCDMA_ONLY

Although I selected a different option that I didn't write down. It was something like WCDMA_HDP_LTE I think.

After that, I was able to connect back to Sprint and things seemed fine, so I upgraded my modem to NAE. Then I upgraded my ROM and I'm having a lot of issues using the phone application, holding a bluetooth connection, and hearing any sounds. I've posted over there to see if my modem firmware may be incompatible with the ROM. But I was wondering if there is anything I can do to "undo" the steps here. I intended to just unlock the device while downgraded so that I would have the option to easily switch in the future. I didn't realize that these steps would leave my phone unable to communicate with Sprint.

I am using the MF9 bootloader (I think - haven't been able to find a screen to confirm this) and NAE modem. Can I still downgrade to MDC to get back to this menu? If not, is there a different modem that will allow me to get here? Once there, can I undo these steps to restore my previous configuration? Or did I actually do things correctly by setting my CDMA menu back to CDMA?

Any help would be greatly appreciated!
[Sprint Samsung Galaxy S 4 General] daniel4653:
You can always upgrade and downgrade the modems. Its the boot loaders that you cannot change. So yes you can Odin MDC modem to access these settings.

I'm using a 5.0.1 GPE ROM and the *#0011# entry doesn't do anything. I've heard that it only works on stock ROMs. Is there some way to get this to work on a GPE ROM?

Either way, is there any way to undo these steps if I do flash back to stock? I know one of the selections entered had 2 options, but my phone said I was currently using option 6 - and I wasn't able to select it after the fact. Is there any 'reload default' somewhere?

Thanks!
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
The unlock must be performed on stock software. Dialing ##72786# in the dialer (if on stock software) will completely undo it and return the phone to Sprint configuration

I currently have an SPH-L720 on Freedompop (Sprint SIM) right now, I was thinking about trying this and using a T-Mobile SIM, but I have one question.

Will the Sprint SIM still work after doing this? or will I have to revert those settings every time?

I thought it would be cool to get one of those Dual-SIM adapters, have the Sprint SIM and a T-Mobile SIM, and be able to switch between both as I wish.
