"If it isn't MDC, you wont. No if, ands, or buts." your wrong you can also do it on MDL just have to select row 0 like 3 or 4 times and it will take you into the service menu.[/QUOTE]

...why not just flash MDC and not have to worry about tapping X amount of times? Let me rephrase what I said earlier "you're going to need MDC or older of a baseband" there ;)

There's a program in the Sprint Note 2 flash to Boost Mobile thread for getting your SPC. The NEW Sprint 16 digit password is in there too. If you have a hard time finding it I'll dig it up once I get off this train.

I did it again don't have to tap it a lot just need to wait like if 10 seconds to load. i guess it don't really matter. but someone might read though here and be on mf9 and there would be no reason for them to flash mdc modem.

Got everything I need, except for how to actually use DFS lol, haven't ever actually used it before. Can you give me a quick walkthru? I don't need step-by-step, but general guidelines would be nice
[Sprint Samsung Galaxy S 4 General] parttimegamer79:
I was able to get mine to work by doing this...

I ran through this guide: http://xdaforums.com/showthread.php?t=2415587 (see page 35 too) then, I followed the OP's instructions and was still unable to get a signal. I didn't get a SIM error anymore but I had no service and my phone was god awful slow. I then noticed that it was running the latest OTA and had KITKAT so, I upgraded my modem to NAE (speed problem went away) and installed this ROM: http://xdaforums.com/showthread.php?t=2673380 - I followed those instructions and added CWM with ODIN ~ NOTE: Make sure you answer yes after leaving CWM the first time otherwise it won't stay as your recovery and you'll have to re-flash it. I then wiped my data and caches and installed the custom ROM. I can verify that after it restarted and I changed to from CDMA to GSM that AT&T (GoPhone), Red Pocket, & net10 all worked after I added their appropriate APNS. It's currently being used on AT&T (GoPhone) with 4G (They have 2 sets of APNS - make sure you use the 4G one from here: http://apn-settings.com/us/att-apn-settings/ -- it's the 2nd one). It works like a champ. IDK if it matters or not but I had the AT&T SIM in the entire time. It was kind of grope and hope but it does work. I'm hoping someone will do it and write up a nice step by step for everyone. I know that I did way more than what was necessary to make it work - I was just running through walkthrus. I was planning on writing it up but it's my girlfriends phone and she's using it - LOL! - Oh and IDK if this is important or not but, the phone was rooted.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
Nvm. Got it. Lmao, biggest f'in derp moment I've ever had, I think. Decided to review the OP for anything I may have missed and discovered I had jumped straight to all the big shiny capital letters and had completely breezed over the international unlock :p

I did successfully rewrite an IMEI back to it with DFS so evidently I'm not a total noob there either. No idea if that would have been necessary as well or if it would have worked with all 0's but it's working now so idc.

I cant flash via odin, My bootleader seems Lock...how can you guys flash the MF9 One click?
[Sprint Samsung Galaxy S 4 General] ecs87:
Haha nice. Sorry about the delay. Work got...hectic. gotta love 12 hour days. Glad to see you got DFS working. It's a very intimidating tool but once you gain enough knowledge on it, it's amazing.

And I've had the international unlock fail a few times. Now something I always do is check for the ICCID upon reboot of the international unlock. If it didn't work (or if you didn't do it) it won't show you the ICCID of the SIM and you'll see unknown SIM in the status bar. If the international unlock did work, then you won't see the unknown sim notification and you'll see the SIMs ICCID in the phone status.

OP, on CM11 I don't think there is a ServiceMode menu. Is that part of the hidden menu that you stated?
[Sprint Samsung Galaxy S 4 General] nicotheandroidguy:
That's because the hidden menu is only for Sprint Touchwiz Roms only.
[Sprint Samsung Galaxy S 4 General] laoh:
Hi, so I did the international unlock not through the steps here but via Sprint's customer service. They sent an unlock update (the CSR confirmed by doing a poll to my phone that did indeed receive the update). So I have not tested whether the international unlock is truly legit (I can't test until I'm out of the country) but assuming it is int'l unlocked, can I follow the steps here for domestic unlock now? Phone is MF9. Thanks.
[Sprint Samsung Galaxy S 4 General] imneveral0ne:
FYI, I was on a T-Mobile ROM with a Sprint kernel, wiped everything, and then flashed a T-Mobile 4.3 AOSP ROM. Worked perfect right out of the gate. Even using the T-Mobile kernel that came with it. Everything works right away. Even wifi/bluetooth and such. Just throwing it out there, because it went a LOT easier than I thought it would.
[Sprint Samsung Galaxy S 4 General] Manik24:
Has anyone confirmed this process with MJA baseband..
[Sprint Samsung Galaxy S 4 General] laoh:
Well this is really interesting. You're right, it seems much easier. Can we just take a nandroid backup of the current Sprint phone, then do the wipe and Tmobile rom install... and if we felt like going back to Sprint, just do a restore of the previous Sprint nandroid? I'm looking for the least painful way, though this method does seem to put you on Tmobile only... with the unlock methods described here, you can potentially have a can-do-everything GS4, the one that works both on Tmobile and Sprint at the same time (Tmobile on GSM and Sprint on 3g) or be able to switch back and forth relatively easily by just doing a SIM swap and updating APNs.

Good to know though, that you can just flash the Tmobile ROM.
[Sprint Samsung Galaxy S 4 General] the.joeba:
Yeah, that's why I'm trying to leave Sprint. My Co-worker has been out since Wednesday so I won't be able to compare with him until Monday. I may pop into a T-mobile store to do some checking. I'm still pretty sure my phone is the cause, but I don't know where to begin.

I'm in San Diego and should be able to use 1900mhz. I tried setting the WCDMA band to 1900 only and it resulted in no signal.
[Sprint Samsung Galaxy S 4 General] imneveral0ne:
Well I've only tried it with T-Mobile service, since I'm not with Sprint anymore. Also it was coming from a T-Mobile TouchWiz ROM. so if you're not coming from that, you may get different results.

I was also able to flash Gummy Rom Android 4.4 sprint version on my phone and get everything working perfectly!
[Sprint Samsung Galaxy S 4 General] the.joeba:
I found another Tmobile phone to try my sim in. It got full bars and 3-4mb/s. It's definitely my phone.

Update: After continued research, I'm starting to think It's my location. This phone appears to only be capable of of HSPA+ over WCDMA at the following bands, 850, 900, 1800, 1900, IMT2000.

T-Mobile uses: 1700, 1900, 2100.

Since only 1900 works (this has been implied in other posts) I'm guessing the other devices were using other bands, and my reception/speeds are to be expected. Bummer.

I try to get into service mode and this is the screen I am greeted with
[Sprint Samsung Galaxy S 4 General] imneveral0ne:
That picture is unreadable on my phone.
[Sprint Samsung Galaxy S 4 General] animal7296:
It says on the top Service Mode. Below that it says no service. I had my international unlock done by Sprint.
[Sprint Samsung Galaxy S 4 General] the.joeba:
This is common. Hit the Menu button on your phone, then choose the "Back" selection from the list, then do Menu again and choose Key Input (or Select, they are essentially the same for this purpose) and enter "1" in the text field and choose OK. You may need to do this more than once. Hitting back seems to bring you to the "MAIN MENU", but not indicating it on the screen. Choosing 1 brings you into the "UMTS MAIN MENU". You should be able to press back again to actually view the "MAIN MENU". One of the first steps in this post tells you to co into the "CDMA" menu. that is option 2 from the top most screen.
[Sprint Samsung Galaxy S 4 General] animal7296:
I tried that several times (at least 20) and I got no where. Oh well. Guess I will have to wait. I am not planning on switching carriers or anything. I root my phone just because I can. I never flash roms anymore. I just wanted to unlock it just because I can. LOL
[Sprint Samsung Galaxy S 4 General] laoh:
Wait, can you clarify?

So you took a Sprint GS4 and flashed it with Tmobile (official) Touchwiz? Did your phone work then?

Then you took that and flashed it with custom rom for Tmobile?
[Sprint Samsung Galaxy S 4 General] the.joeba:
Are you on Baseband MCD? I updated to MF9 and couldn't get past "No Service" until I downgraded back to MCD.
[Sprint Samsung Galaxy S 4 General] nicotheandroidguy:
Ok Guys AT&T is confirmed working with MF9! Yes I have a custom HSPA+ icon. BTW it is on band 5 EDGE works as well as voice text internet and mms. I'm using a red pocket sim I will be ordering a go phone sim to test and aio if I can find one on Amazon. Use my method on T-Mobile unlocking and this should work on AT&T as well I'm on MF9. Also HSPA+ is working.

You might want to try switching the hiddenmenu option to on in efs/carriersetting/hiddenmenu (note that the files are hidden by default. Use a text editor to open the hiddenmenu file and change off to on or no to yes I forget which it is. Then reboot and try again.

excellent man, I'll update the guide.

So we have t-mobile, simple mobile, Att and straight talk all confirmed working in some markets. And confirmation that you ARE able to update to mf9 and keep the unlock. I haven't updated yet but will and will update the guide accordingly.

Thanks for the feedback guys, I'm trying to monetize this in the phx market but it seems that we might be the only people interested, ha!

are sprint gs4s able to be unlocked this way by flashing a tmobile rom?? I want to use metro or tmobile on my sprint gs4

Sent from my SM-N900V
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
Sigh.

READ THE THREAD.

(Although it's not really your fault that the OP needs to be updated, so I won't blame you too much. You don't use the MF9 one-click. You can't revert back once you're on 4.3 - you will end up hard bricking your phone. All you need is the MDC modem. Flash in Odin, and then you have access to the service menu. Remember to do the international unlock first.)

Yeah I after the dialer steps, I was still getting the Invalid SIM message which surprised me but Verizon phones show that when you put another SIM in so I just figured that's how it was. Message disappeared of course after international unlock - worked on first try (MK3). Herp-a-derp :p

PAC-Man T-Mobile Rom for LTE

im a noob to this i fully got my s4 working on t-mobile network the most i get H+, the PAC-Man T-Mobile Rom will allow me to get lte on my s4
[Sprint Samsung Galaxy S 4 General] skrapmetal:
You get 4g with that ROM? Or just H+? Just making sure I understand correctly.
[Sprint Samsung Galaxy S 4 General] delvin101:
i have the stock rom for touchwiz, the most im getting is h+, no 4g at all on my s4.... is there anyway to get 4g??
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
HSPA+ *is* 4G. Just like LTE is. The Sprint S4 does include support for 2100MHz LTE, and T-Mo uses 1700 and 2100 for its LTE (as of right now). So theoretically yes you could be picking up LTE. But keep in mind that the ROM could just use LTE for the icon to indicate any 4G connection, so you may be on HSPA. Only way to know is to look in the settings, or use a network info app.

[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
This has already been answered many times. Read the thread.
[Sprint Samsung Galaxy S 4 General] ecs87:
THIS, EXACTLY! (Recent) Sprint phones do not have the ability to display 1x (2g) so it displays a 3g icon and you'd never know until, like mentioned, you go into the settings. The same can be said for different roms and different connections (ie seeing HSPA under a LTE icon in a custom ROM).

[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
I kinda find that hard to believe. What would the phone display if you were a Sprint customer using the phone on Sprint in a Sprint 1X area...? I would think all their stock ROMs have the 1X .png for when the phone is in one of those areas... It might not display that if the phone is on a GSM 2G network, but for CDMA I'm sure it's included..

[Sprint Samsung Galaxy S 4 General] Soggytoast111:
Success!

Hey everyone, I'm on AT&T and just successfully unlocked my phone last night. I am basically a complete noob at this but learned everything by lurking around this forum. Now I have full voice, sms, HSPA+ data etc. on AT&T with no major hangups. I just wanted to share because the info in this thread seems to be kind of all over the place.

I started with a virgin Sprint Galaxy S4 with 4.3 and MK2 modem. All OTA upgrades. No root/custom ROM or anything - KNOX untripped. Consider it straight out of the box.

First I flashed down to the MDC modem using ODIN. I had trouble at first making the connection with ODIN but then it worked fine when I switched USB ports. I only flashed the modem file, no other firmwares. Still stock 4.3 TW.

Next I ran through the international SIM unlock tutorial here:

http://xdaforums.com/showthread.php?t=2415587

No problems at all - inserted my AT&T SIM and no longer have "invalid SIM" message.

Then I did the steps in the first post of this thread.

The first time when I got to the *#0011# service menu, it only said "no service" and I couldn't figure out how to get to the options. I then changed the network mode to GSM, and it displayed a bunch of numbers. That's when I realized that you have to go to the left menu soft key and press back before you "key input". It's not clear from step 4 that you have to press "back" first. It will just sit at the "service menu" screen otherwise and you won't be able to access any of the options.

So then I carefully ran through the rest of the steps here and... it didn't work.

Oops. Network mode has to remain on WCDMA (not GSM) or else it doesn't work. I turned it back to WCDMA, went back to *#0011# service menu and repeated the steps in this thread. Set my APN for AT&T 4G and I have voice and SMS! But only Edge data! Ewww.

The final and critical step was going back to network mode and setting it to "Automatic". Phone reboots and I have full voice, SMS, HSPA+ data!

No need for special firmwares or rooting.

Good luck everyone!
[Sprint Samsung Galaxy S 4 General] Soggytoast111:
Quick update:

Today at lunch I noticed that I was losing service because the phone was still trying to connect to Sprint. I went to settings and changed the network connection from "Automatic" to "GSM/UMTS" and I got back to AT&T with HSPA+ data still.

I was worried about playing with the network settings because the service mode settings you play with throws that over to "GSM only" (which isn't even a menu option). But it seems to be working fine with "GSM/UMTS"

I have a feeling that at least some of those settings in the service menu don't have to be changed to accomplish this unlock... but I doubt anyone would be a guinea pig to test them all out.
[Sprint Samsung Galaxy S 4 General] ecs87:
If you switch anything in those settings I'd suggest redoing the service menu instructions. Your phone settings should say WCDMA only, not GSM and not WCDMA/GSM. That's particularly why we need the service menu. I don't think just selecting GSM/WCDMA will work.

nothing i added the apn for my carrier and changed the network mode to umts and nothing

i downgrade again from nae to mdc and do the steps for *#0011# any signal still

thanks in advance
[Sprint Samsung Galaxy S 4 General] Soggytoast111:
Umm... as I said before I have it set on "GSM/UMTS" and it's working great. I'm not going to go back and play with the service menu settings and risk breaking anything.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
If you went back to MDC again and successfully did the dialer code steps, and it's still not working, the phone may be blacklisted

Yeah leaving a CDMA phone on Automatic will always have it default to CDMA first. Leave on GSM for best results

Time to consolidate this yet?

Can we split all of this up and clean it up a bit? Who's willing to help me?

I have a Sprint SPH-L720 that I want to use on either Verizon prepaid cards or Metro PCS... But I've read through 40 pages and still don't think I know how to do this properly for either carrier option.

I'm willing to do the write up and give all credit due on whichever one I flash. I am quite capable writing it all down in an easy to read, step by step format. I just need someone to help walk me through it so I know exactly what I'm doing, and so I can simplify the process.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
The OP does need to be edited a bit, but all the steps remain the same.

This is NOT a thread about getting an L720 to work on a CDMA carrier. If that's what you're after, look elsewhere. If, when you refer to Metro, you're referring to the GSM side of their network, then this method will do what you need.

Hmm I've never seen an app mentioned. But glad to hear you got it working.
[Sprint Samsung Galaxy S 4 General] ecs87:
As far as I understand (from my understanding of how the NV/efs system works) the GSM settings are fine, but go to Edge for data. WCDMA gets you HSPDA. It may be working "great" now, but it may grab GSM in a certain spot over WCDMA and you may experience troubles. Also note that on all the L720s i unlock say WCDMA only in network settings, not GSM/WCDMA. I just hate it when customers come back to the shop I work at so I like to do things right the first and last time. Again, I'm not TELLING you to redo it, I'm merely suggesting.

Also you'd be hard pressed to mess something up unless you randomly start tapping on things. If you redo the instructions it'll either stay the same if it's already working or it'll correct whatever was wrong.

The hidden menu always opens. I've done over 30 of these. You may need to mess with the back selection then key input 1, but it ALWAYS works for me. You may also not be patient enough to see it. On some phones it comes up quickly. On some others...not so quick. No APKs needed, no build.prop edits, no rooting, no custom recovery, no custom ROM, and no tripping KNOX.

I dunno why you're trying to root or put a NAE baseband on. If you're on MF9 you want to use the MDC modem (ONLY THE MODEM OR ELSE ODIN WILL FAIL AND SOFT BRICK YOU) for the international unlock program and for *#0011#. Only AFTER you've confirmed you're unlocked then you throw the corresponding baseband back on (if your software version is MF9, put the MF9 baseband back AFTER the unlock is DONE, NOT NAE!!! Only use the NAE baseband if you have a NAE software version.)

If after 5-10 minutes you don't get signal (or get it for a few seconds and it disappears) then the phone is blacklisted. You're going to need to be familiar with DFS CDMA tool (free version) to fix it.

You'd have better luck reading Alpineman's flash to boost/pp/cricket thread for the Sprint Note 2 (L900). You don't unlock a phone to a CDMA carrier. It's much more in depth and you're going to need to be familiar with CDMA workshop and DFS should you need to reprogram your phone manually. It's not for the faint of heart and you CAN mess up your phone BAD by messing with settings in these CDMA tool programs should you feel curious and not know what you're doing. It's possible to do what you want to do though.
