I literally just this very moment (5am PHX time) got Tmobe working for this bad boy, 3g and HSPA+. I also experienced the problems that you did in accessing and manipulating the hidden menu and also had to alternate methods to get it to do what I want. I also used an unactivated tmobe sim.

Try going into the cdma options, the common menu, and back a page or two where it says "Pref Mode set" and select gsm_wcmda_only , then proceed back through the watchdog steps. Also pay close attention to what [MENTION=4988907]nicotheandroidguy[/MENTION] changes inside the umts/debug/phone control.

I wrote a really detailed guide for what I did and planned on publishing it, but about two hours ago I got too dialed in and forgot to write down all the options I changed. I'm gonna sleep for a few and try to replicate it tomorrow.

Be careful not to change anything in the hidden menu without at least reading about the options you are changing.

HOORAY DOMESTIC UNLOCK AND NOT BUYING A NEW PHONE!!!

The hidden menu app is like a tin can radio. I found that *#0011# the menu, select line 1 or 2 then any combination of menu/back menu/input menu/back/back/back seems to kick you out as well. Also make sure that you have edited your build.prop to include the hidden menu, I had zero luck before doing that.

---------- Post added at 05:27 AM ---------- Previous post was at 05:21 AM ----------

It looks like you might not have switched your preferred network correctly in the hidden menu. Under CDMA/common pg 3, pref mode set to gsm _wcdma_ only then do the six taps on watchdog and reboot.

Thanks I'll keep that in mind next time it breaks! Mine randomly just turned on by itself at 5 a.m. this morning. Wasn't even touching the phone, came back and it had hspa+ and everything works. Wish I could explain it.

And now my texting just randomly stopped working. Wonder what that's all about.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
I'm so scared to flash an AOSP ROM it's not even funny lol. But the battery life on this TW is not too swell! Quiet scared to mess with the modem as well. Will flashing another one actually do anything? Or do the new modems just change CDMA/LTE stuff?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
I'm not sure I think it might that's why I haven't updated the modem so I would flash Triforce rom its the only MJA 4.3 Rom I could get to work I tried the sock MJA and SACS they were stuck on the Galaxy S4 screen. But Sacs rom 4.2.2 works great with the unlock and the hidden menus. If you dont need Sprint I would flash a T-Mobile or i9505 rom with a Sprint kernel and GSM works great for GSM only.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
I absolutely do not need Sprint, wasn't aware we could flash GSM ROMS with a Sprint kernel. Does that work for AOSP as well? Or just TW?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Just TW.
[Sprint Samsung Galaxy S 4 Android Development] dino_mk:
I was getting same error. Solution was just to reinstall modem again.

Hey I have been trying this tutorial to unlock my S4 with a Metro SIM. I got the first unlock to make the Invalid Sim error disappear but after following nico's screenshot guide I was not able to get as far as you however such as my network settings show unknown for carrier and just my sprint stuff. Anyhow that has just been my attempt.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try to do my unlock with a T-Mobile prepaid sim then use the Metro Sim Make sure it is active or else it might give you a emergency calls only error. Let me know how this works out for you.
[Sprint Samsung Galaxy S 4 Android Development] imbmiller:

I carefully verified all the settings, went into perfs mode set and made sure it was on GSM_WCDMA, attempted the watch dog step again (is there supposed to be any indication that it was done correctly?), but no networks show up at all. I'm really wondering what I'm missing!
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Not if you change it to gsm/wcdma by dailing *#*#4636#*#* device info then scroll and make sure your on WCDMA perfered then add the apn.

---------- Post added at 08:32 PM ---------- Previous post was at 08:31 PM ----------

After doing the watch dogs immediately reboot then let the phone sit for one minute after boot and you should be on T-Mobile.
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
Tried this, still only getting the no signal symbol (seems it's expected) but no networks are found ever in "Network operators"
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Make sure your phone is in gsm/umts mode then try again if not you might not have T-Mobile service.
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
GSM TouchWiz rom works so much better. No connection issues at all. Thanks for the tip man!
[Sprint Samsung Galaxy S 4 Android Development] the.joeba:
I'm positive i'm in gsm/umts mode when trying.

I'm going to try tracking down an active sim to see if that makes a difference.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
ok so.. i followed nictheandroidguy steps.

I am still having issues but here's where i stand.

I used hiAPN global to get the phone to show my T-mobile APN.

T-Mobile US epc.tmobile.com

However, i still have a circle with line through it (no signal).

Under mobile networks, I have set it to gsm/umts and when i try to search for tmobile NOTHING shows up.

I did create a nova launcher shortcut to the testing menu and set the preferred network to wcdma (auto).

Any ideas on what i did wrong/how to get this working?

I appreciate your help.

PS- this is a tmobile sim card for the $30 5gb 4g lte data 100 minute plan.

Thanks,

Rob
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
That should make the difference or use a T-Mobile prepaid one thoose work if they are not activated and if you need to activate one put your imei as 999999999999999 and it would work to activate the phone.

---------- Post added at 07:53 AM ---------- Previous post was at 07:51 AM ----------

Redo the steps with the T-Mobile sim in the phone and put it on Gsm/Umts mode and for the watchdogs immediately reboot and let it sit for a minute and it should work.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
im going to try that right now.

as an alternative.. i was reading that users suggested flashing a tmobile ROM with sprint kernel... would that also work?

Would i need to flash a tmobile MODEM/RADIO? As the sprint S4 currently is on MDC (not sure if that's the same for sprint/tmovile)
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
You can Flash a T-Mobile Rom with a Sprint kernel don't flash the T-Mobile modem I haven't gotten it to work but you could try it, it could also brick your phone so proceed with high caution MDC MDL and MF9 are the only software versions I've tested the unlock with.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
Copy that.

I'd prefer NOT going that route, but if all else fails.

I'm in the process of re-trying the Service Menu steps.

I'll update you momentarily.

1 Debug Screen -> 6 Phone Control -> 1 DRX Control = GSM DRX: ON / LTE DRX: Enables RX0 and RX1

what do i want to enable there?

i enabled GSM DRX and it then said on... when i then selected the LTE DRX for RXO and RX1, my phone automatically rebooted (without me prompting it to reboot).

Was that supposed to happen?
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
OK thanks.

I keep trying to run this line

1 Debug Screen -> 6 Phone Control -> 3 Nas Control -> 3 Sim Class Control = UMTS

and i get menu not exist press back key...

any thoughts?

Ok Got past both these issues... Rebooting and on to the watchdog steps.

---------- Post added at 06:33 PM ---------- Previous post was at 06:26 PM ----------

Ok... i hit the SW and HW watchdog (option 2 and 3) 6 times each and then rebooted...

The phone started up and i chose GSM/UMTS but when i manually search networks, nothing comes up (still just sits with cirlce with line through the signal).

On the Watchdog steps... I did not go back to main menu in between hitting each one 6 times does that matter?

Any other thoughts?

I see Tmobile in my APN but it's not finding the network.

P.S.- I had loaded my sim up with $30 so it's "active"
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Try the 2 nd option watchdog 6 times then do menu back it should remain on the same screen then do the same for the 3rd option watchdog then immediately reboot dont search for networks before and after. Leave it on gsm/umts before you start the process make sure the tmobile sim is in during the whole process. If all else fails do the watchdogs again then select the first option in that menu modem reset then immediately reboot.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
Still no go...

I set the phone to gsm before I attempted the watch dog steps... performed them, but still not picking it up.

It should not be this difficult, am I missing something
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
No your not missing anything try sacs custom rom the 4.2.2 one I used that when I did my unlock.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
I'll try that.

On the sw and hw steps... I enter the simulation screen, hit sw 6 times hit menu then back then enter simulation and hit hw 6 times then hold down power and reboot right?

Just want to make sure I'm doing the sequence correct.
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
Yes you are good luck some people have reported success and others haven't so good luck. Keep me posted.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
No go on sacs...

The interesting thing was ask the settings from the service menu wee already set correctly...

Thoughts?
[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
I loaded up my sim, and it took 24 hours for it to actually activate. Once it did, the phone just stayed working on is own.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
Very interesting.

I completed the activation last night around 7...

I'll give it a day or so and try again.

Thanks all
[Sprint Samsung Galaxy S 4 Android Development] nicotheandroidguy:
I'm not sure. Try fully updating your firmware and modem to MF9 as well use Sacs 4.2.2 rom then try again. Good luck. Keep me posted.
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
I wonder if Sprint/Samsung "fixed" this with the MJA modem so the watchdog trick no longer works. It's really weird that it even works at all to be honest.
[Sprint Samsung Galaxy S 4 Android Development] h20wakebum:
Im not on MJA, MDC is my current radio

i'm going to try flashing MF9 and see what happens

So.. I actually did download a Tmobile Rom and flashed it, succesfully booted up but i still had no network signal...

This leads me to believe it really might be that my sim card hasn't truly activated...

Thoughts?

now that the domestic unlock is more out in the open.. hopefully Sprint doesnt catch wind of this or they will request future Samsungs not allow this.

the intl unlock is a system that cant be reversed.. domestic would be easy to block.

Edit Never mind got it to work thanks to you guys, There are two different kinds of GSM MetroPCS SIMs. Ones that have the dot that looks like the sprint one. And one that doesn't. The one that doesn't have the dot will not work.

[Sprint Samsung Galaxy S 4 Android Development] imneveral0ne:
Care to upload a picture? I plan on going with metro next month since it's the same plan as t-mobile but for 10 dollars less a month. AFAIK, it's the same exact service.
[Sprint Samsung Galaxy S 4 Android Development] TheZander:
Picture of the SIM card? Or proof that it works on the phone. If you want a screen shot let me know of what and I'll do it.

Metro is exactly the same as TMobile since they're practically one. It's a good idea to get them. 60 a month unlimited 4G data good stuff. 40 bucks unlimited everything. And you can practically dual run Sprint with just a change of the settings.

We got sweet 4G coverage in michigan as well so its a good call.

Hi all,

I have a Sprint Galaxy s4 mf9 stock which has been unlocked by sprint. I have confirmed this because I don't get the invalid sim message. I have arrived in India and now I am trying to use a local sim here. The sim has been inserted and I have changed the network type to gsm/utms. However, I get a circle with a line thru it where the signal is to be shown. I try to click on mobile operators and when it searches there are all the results of the local phone operators here. However, when I choose the local one I have, which is Vodafone IN, I just get a message saying unable to connect try later. If I choose automatic, same problem. I never get the signal bars. Also, I have tried this sim in another full unlocked GSM phone here and the sim works normally. Please help on what I may be missing so that I can use this phone while I'm here. Thanks so much for any help.

For those looking for APNs, check my post in the first few pages of this thread. The APN xml file I linked has over 1400 entries. Chances are high that wherever you're going, the appropriate APN is already in there for the gsm carriers in that country.

BTW, you're only going to get 4G LTE and 3G on the Sprint network... HSPA, HSPA+, or 3G on others. Doesn't matter what APN you use.

I received an unlock via Sprint International. They say it's unlocked, but i want to verify it on my end. So as per your OP, if I see a number under ICCID in my phone status and not "unknown" even thought I did not insert a different SIM card that would verify that my phone is actually unlocked? Or do I have to use a different SIM, and see if the ICCID status remains with the numbers I see now, and I don't see "unknown". Thank you!

Any help would be appreciated.

I got the phone unlocked using Auto's method... but, I will want to use SMS/MMS/DATA overseas in the Philippines.

I downloaded offline APN database pro which allows me to see APN for the carrier I'll be using (SMART)...

But... as I'm on 4.2.2, how do i update/change my APN to reflect that?

I did download Titanium backup pro and set offline apn database pro as a system app... so... even though it's telling me it can't write because i'm on 4.2.2, is it working?

Any help would be Appreciated!!! Immensly!!
[Sprint Samsung Galaxy S 4 Android Development] E:V:A:
So it's only used for DFS? (And subsequently have nothing to do with the phone?)
[Sprint Samsung Galaxy S 4 Android Development] Ingenium13:
You still need root to use that app on the S4, since it needs to be made a system app. I tried using it as well but the build.prop edit was easier for me.

As of MD9, if you want data on GSM, you will have to root. You can use an app, or a build.prop edit, but all the ways to edit the APN require root currently. This may get fixed with a later software update.

When you get a SIM they will tell you what the APN settings are for that carrier. Or Google them. Just add them after you put the SIM in and connect to their network. If you don't care about mms (that involves more detailed settings) then it's often just a single word, you can leave the other fields blank. For example, for the Costa Rican carrier Kolbi, I just needed to set the APN to kolbi3g and that was it.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
It worked fine, then I used the second download to get back to MF9, now I don't have the GSM/UTMS under more data section.

Only CDMA and CDMA/LTE.
[Sprint Samsung Galaxy S 4 Android Development] HeXacTa:
Thank you so much. It works very well here. Outside US and non sprint carrier.

May I share this on other forum (local forum here) with link to this thread?

i can't find any APN setting. when I change build.prop, I lost option to GSM on mobile setting instead.
[Sprint Samsung Galaxy S 4 Android Development] autoprime:
You need to pop in a GSM SIM card(not Sprints) and see if ICCID shows up.. or if you get a Invalid SIM error. If you see ICCID.. or see no error while the GSM SIM is inserted.. you are unlocked. You can use ANY GSM SIM.. even ATT/TMO to test(this does not mean you will get service on tmo/att).

The "DFS" password is not related to DFS... it is the basebands AMSS security password. You can find reference to this in QXDM and all sorts of PDFs. It's a password that can be found in the modem.img itself.. but a pain to find unless you know what you're looking for. The password has "powers" to unlock the EFS above what the SPC would allow. This seems to mostly be used by Samsung.. altho if you look around the net you'll find some other devices that use it. It is often referenced as the "QXDM 16-digit password"

Well that is certainly weird. Were you on a stock MF9 rom while you did this? Used Odin to flash the MDC modem.. then used Odin again to flash the MF9 file? I cant think of any reason why flashing the MF9 bootloader would remove GSM settings. Current ideas to fix this include... reflashing a rom. or wiping data in recovery. or flashing a full stock tar in Odin. Or using ##786# to reset the phone.

I've never seen the GSM menu disappear myself. And it doesnt look like anyone else ran into the issue either.

has anything else happened that you can think of? and have you tried anything else to get it back?

Please share the link only. I'd prefer you not copy the entire thread into a new thread on your forums. But a link on your forums I would be fine with. Thank you for asking.
[Sprint Samsung Galaxy S 4 Android Development] pvinodnayak:
Nothing as of now. I'm working now, so won't be able to try anything now.

When I odined to MDC(baseband)I lost root and recovery. After unlocking I reverted back to MF9 and used CF Auto root. Nothing else.
