Thanks for the help. I sure wish it was that easy. I'm on NAE and it doesn't have a voicemail in the contacts. I did add a voicemail of my own and even set it to call it if I hold the 2 button down. It wouldn't work on the 1 button. But there are still no notifications if I get a voice mail.
[Sprint Samsung Galaxy S 4 General] Dreams2Reality:
:good::good::good:

I didn't know people still said banhammer, lmao

--

For people switching to a custom rom, all i had to do was switch the mobile network to gsm/wcdma auto from the basic settings.. "via slimkat". So dont be scared to go to a different rom, ha..

:cool::eek:

Im also on NAE.. really you dont need to worry about the voicemail not being in the contacts.. just add your own contact with it's number and call from the contacts.. its pretty easy..

If you are on T-Mobile, just download the voicemail app from the playstore.. everything works fine
[Sprint Samsung Galaxy S 4 General] Awkh87:
Any possibility the SIM can still be unlocked.?! 'IF' the phone is a Boost Mobile flashed Sprint S4 [Incognito donor] ..?!

All the radio settings and IMEI have been replaced with the donor phone.

Just wanting make sure before even trying unlock it.
[Sprint Samsung Galaxy S 4 General] gspears:
Thank you and I have done that but as I stated earlier this works and I even have it set up to go directly there if I hold the 2 button but I get no notifications of any voicemails received.
[Sprint Samsung Galaxy S 4 General] daniel4653:
I found out that flashing an ATT ROM fixed my MMS issue.
[Sprint Samsung Galaxy S 4 General] Dreams2Reality:
You have AT&T correct? AT&T has a visual voicemail app.. download it and it should work. I think that is the only way you will get notifications.

Also, when I flashed SlimKat rom, my MMS started working right away.

:good::good:
[Sprint Samsung Galaxy S 4 General] daniel4653:
awesome! So that shows us that there are some left over sprint files that block MMS
[Sprint Samsung Galaxy S 4 General] gspears:
Thanks guys. I'm going to flash Omega. Hopefully it works.

I'll let you know.

Update: Omega works great. I just rooted, flashed recovery and flashed omega. No mods of any kind. MMS, Voicemail, and everything else is working well.

I forgot to mention that AT&T told me that since this phone could not get 4g, it cannot use at&t's visual voicemail.
[Sprint Samsung Galaxy S 4 General] Tekone:
I read through OP and prepare to SIM unlock for international. If this method can unlocked for ATT/TMO, it should work for international sim as well right? If a Sprint S4 sim unlocked for ATT/TMO, can it still work with Sprint Network?
[Sprint Samsung Galaxy S 4 General] boyzone:
Does it still work with Sprint after this is done? Has any one tested on Sprint? I would like have this switch between Sprint and T-Mobile!

Thanks.
[Sprint Samsung Galaxy S 4 General] daniel4653:
Read please. This doesn't affect sprint service. And yes you can switch between the two.
[Sprint Samsung Galaxy S 4 General] joem789:
This is probably the most effective method I have used so far for my L600. Yes. I know this thread is for the L720. But the menus all seem to be the same. My phone now uses WCDMA/GSM exclusively. And it picks up the AT&T network and attempts to register to it. But it fails. Why? I suppose it may be because my Sim is still locked. The phone still shows invalid Sim. And the Sim lock feature in Settings is still ticked with a PIN that Sprint put in there. I wonder if there is some way for me to unlock the Sim. Once that is done, I think the phone will register on the AT&T network.
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
The exact same thing would happen if you did the service menu steps to an S4 but without performing the international unlock. That step must also be processed for the phone to be completely unlocked. A method would have to be discovered whereby to reverse engineer the OTA international lock that Sprint performs to the L600 (the Mega IIRC). The SIM lock has nothing to do with what you're talking about - you can merely lock the SIM with a PIN to prevent it from being used, just as you can lock your phone's screen with a PIN
[Sprint Samsung Galaxy S 4 General] tacoman1423:
unlocked!

Unlocked on NAE firmware & build.

Downgraded modem to MDC for international unlock.

Upgraded modem to NAE then did the domestic unlock.

For those that might have trouble with the *#0011# menu and getting the "Menu not Exist" after doing back and key input "1", try replacing the "1" with "Q" then key input "0000"

Currently on Docomo Pacific! Weird that Docomo Pacific was considered Domestic, I had the phone unlocked for international and the phone was able to read the sim, but no signal (x with no bars). After unlocking for domestic, everything was good, voice & data.
[Sprint Samsung Galaxy S 4 General] Mazrx:
I had done this and almost finished then the friend I was doing this for said that he was staying with sprint...:eek::eek: I was originally doing this because he told me he was switching to ATT. I stopped at step 11 and now the phone has absolutely no service how can I just reset everything so the service and the settings are reverted to normal again on original Sprint Settings? Thanks in advance.
[Sprint Samsung Galaxy S 4 General] Mazrx:
Fellow UCR Highlander I will be a freshman this fall :D Could you possibly help me out with my problem?
[Sprint Samsung Galaxy S 4 General] aviara:
A friend of mine has successfully unlocked his 720t using this method in conjunction with something else... Developing..
[Sprint Samsung Galaxy S 4 General] skrapmetal:
Pics or it didn't happen ;)
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
A ##SCRTN# from the dialer should undo everything, though it's really not needed. You should be able to choose CDMA/LTE from the Network Mode selection and have everything fine

Hmmm. I'm gonna stay cautiously optimistic.
[Sprint Samsung Galaxy S 4 General] Mazrx:
Wow, thank you so much for your precise answer...:D:D:D
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
What's up guys...I've been breaking my head back and forth playing with settings...I have followed the steps 1 by 1 and there's no way for me to get data to work on Sprint s4 straight talk AT&T...I managed to get talk and text but data has been a bug...tried so many apns etc....is there anybody that is willing to help me out im willing to donate as well that's how much...Sorry to bother and thanks
[Sprint Samsung Galaxy S 4 General] daniel4653:
Have you gone into settings are removed all of the roaming guards plus allow domestic data?
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Thanks for helping but I've tried checking both on and off...for some reason I can't click the greed out part of the settings as you can see in the attached pictures. ..any other ideas thanks
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Forgot to attach sorry
[Sprint Samsung Galaxy S 4 General] skrapmetal:
Post a pic of your APN settings please. My data works fine with straight talk on my Sprint. It would NOT work on SAC's ROM but it does work on Negalite ROM and SOKP ROM. It does work on the stock ROM also.
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Looks something like this...The current apn...help me please(Marlon Wayans voice) lol
[Sprint Samsung Galaxy S 4 General] skrapmetal:
MMS port 80? You have your network type set to gsm, correct?
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Yeah 80...I currently have it gsm...but I tried wcdma only too and nothing
[Sprint Samsung Galaxy S 4 General] skrapmetal:
Assuming you did the unlock correctly, and didn't miss any steps, and you have data enabled, you could have a faulty sim card.

Smart network mode thingy is turned off right? If your phone sees WiFi, it won't use data, it will just switch back to WiFi.

I had luck once pulling the battery, removing the sim and wiping it off when I wasn't getting a signal too.
[Sprint Samsung Galaxy S 4 General] xuser:
Thanks. I'm still a bit confused on the steps. Maybe the OP can add this method to the OP. Did you also do the SIM international unlock prior? I wonder if it would work on a Sprint phone with a "Bad ESN"? :D
[Sprint Samsung Galaxy S 4 General] DAFTEK:
I have done the sim international unlock from sprint, but I have not traveled yet outside. I am hopping I wont have any problem when I do go to europe.
[Sprint Samsung Galaxy S 4 General] imbmiller:
Basically what he is saying is do steps 1-11 and then flash a tmobile rom with a sprint gs4 kernel and you won't have to change your apn etc.

So yes he did the international unlock, and yes it works with bad sprint esn s.
[Sprint Samsung Galaxy S 4 General] xuser:
OK gotcha, all clear now. The T-Mobile ROM just simplifies the APN settings. Would be cool if we can get some type of automated program for the steps 1-11 to make it a "One Click" hack. Thanks again!
[Sprint Samsung Galaxy S 4 General] premiumg:
Damn... I went through all the steps successfully. I'm not able to confirm domestic unlock though.

I have MetroPCS and am unable to get my Sprint phone to work on my SIM. Metro requires you to call in and register the IMEI/ESN with them before the SIM will work. When I called, they said they are not able to register using the DEC or HEX number I provided and clarified they will only activate Iphone for Sprint....

I guess my choices are:

1- sell this phone, get a proper GSM unlocked one

2- switch carriers to T-Mobile or Simple Mobile
[Sprint Samsung Galaxy S 4 General] heartless-1:
the imei is missing one number in the back, on mine when i had to dial *#06# and found out it had one extra digit that wasn't present in the back of the phone
[Sprint Samsung Galaxy S 4 General] premiumg:
You've given me a lot of hope! I'm gonna try calling Metro PCS again.

Did you get your Sprint GS4 working on Metro?

---------- Post added at 06:59 AM ---------- Previous post was at 06:02 AM ----------

damn.. i got the missing digit at the end. Metro PCS was still not able to activate using the HEX number from the Sprint GS4. The representative said IMEI should start with 359 (what they usually see).

Has anyone gotten the Sprint GS4 to work with MetroPCS?
[Sprint Samsung Galaxy S 4 General] heartless-1:
i did it for a friend on saturday, (metropcs byod) we gave them the 99 number with the missing digit and they registered it. most of those reps are knowledgeable but some...not so much. i'll try to register another one tmrw and report back.

another note, anyone else try with mja, i can get it setup for about 3 seconds: reads t-mobile network on the carrier label then changes to emergency mode. also i can receives calls but can't make them.
[Sprint Samsung Galaxy S 4 General] premiumg:
Thanks heartless. I tried calling Metro again hoping to get a rep that has more knowledge. I used http://www.meidconverter.com to get a "Metro PCS SPC". I was careful not to say that I am using a Sprint GS4. When they ask me what device I'm using, I said it's a Galaxy S4. When they asked what carrier it was previously used for, I said "I don't know, it bought it unlocked". With the "Metro PCS SCP" and the extra digit, I was able to get my Sprint GS4 activated.

However, I am only able to make calls, and send texts. i cannot receive texts or calls. With texts, nothing happens. With calls, I get "Subscriber you have dialed is not in service. If you feel you received this message in error, please hang up and try your call again later. Message CA25756".

I've tried HiAPN with no luck. At least I'm half working now. Able to send texts and make calls outbound.

If you have any insight, that would be greatly appreciated.
[Sprint Samsung Galaxy S 4 General] imbmiller:
The apn setting only pertain to Mms and data, not calls and text. It sounds like you aren't set to wcdma preffered or have an android setting set incorrectly like roaming guard or ROAMING settings.
[Sprint Samsung Galaxy S 4 General] premiumg:
Thanks for the tip imbmiller. I think I might have missed a step.

For step 4 to step 5, you said this:

"Depending on if you pressed 1 or 2 in the dialogue box it will take you into either an UMTS or CDMA menu.

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

I did not get CDMA menu, I got UMTS menu. I see "COMMON", but how do I get to page 3? (how to get to next page of common)? I don't see next page as an option on "COMMON" page. I see:

COMMON

1 FTM

2 DEBUG INFO

3 RF SCANNING

4 DIAG CONFIG

5 WCDMA SET CHANNEL

6 NV REBUILD

7 FACTORY TEST

---------- Post added at 01:34 AM ---------- Previous post was at 01:17 AM ----------

I found the CDMA menu now. To get to the CDMA menu, I had to go "back" from the UTMS menu.

I was able to find "COMMON" and then next page x3 times. I set 8.PREF MODE SET and select GSM_WCDMA_ONLY.

I then searched for MetroPCS under networks and was able to find it. I registered with MetroPCS, but still not able to receive calls or texts.

imbmiller, I flashed a Tmobile ROM and used a Sprint Kernel so i don't have access to the Roaming guards or ROAMING settings anymore. Do you think that could still be it? (even though my rom doesn't have the settings?)
[Sprint Samsung Galaxy S 4 General] premiumg:
Ok, my Sprint Galaxy S4 phone is now working on Metro PCS. I figure I'd try giving Metro PCS support a call to see if they can fix the issue. They had me run the the standard pull out battery and SIM card. When nothing worked, I asked him to "reactivate" or "reset" my activation.

That seemed to have done the trick!

Thanks much to Imbmiller, heartless-1
[Sprint Samsung Galaxy S 4 General] imbmiller:
I'm glad you worked it out. I edited the guide to clarify the parts where you had difficulty.
[Sprint Samsung Galaxy S 4 General] heartless-1:
metros weird sometimes, today i registered my imei on friends metropcs account to test it out (worked), and like yours also had to do an account reset. customer care calls it "resetting the switch". glad you got that up and running
[Sprint Samsung Galaxy S 4 General] fergdizzle9090:
can it use att 4g or lte? what the fastest signal speed like?

also im on mdl and will unlock it but once im done unlocking what firmware can i update to without breaking the unlock? or does the unlock always stick? and i am rooted now as i need to be correct? and would like to unroot and put everything stock after it is on att, can that be done?
[Sprint Samsung Galaxy S 4 General] premiumg:
Mine is MetroPCS and is using HSPA+. I'm a novice to this, so I've no idea if the unlock sticks, and if unroot will break unlock...
[Sprint Samsung Galaxy S 4 General] premiumg:
Which modem do you guys recommend? I'm using MDC now. Should I update to MDL or MF9? (reading from previous posts in this thread, it looks like I can do so without breaking the domestic unlock, but not to the MJA modem)
[Sprint Samsung Galaxy S 4 General] yougivemerash!!!:
If I flash a tmobile rom, will Tmobile wifi-calling work? Can anyone that's flashed a Tmobile rom on their Sprint S4 answer this? Thanks.
[Sprint Samsung Galaxy S 4 General] hayat4:
Thank you for asking that, can anyone help answer this please?

and perhaps provide a link to the tmobile rom?
[Sprint Samsung Galaxy S 4 General] nicotheandroidguy:
Yes it does work I've tried it on my sprint S4 I used the stock T-Mobile ROM in the android development section.
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Weird man...not faulty I have a backup nexus 5 with data working and all...smart network Is off a day nothing
[Sprint Samsung Galaxy S 4 General] skrapmetal:
So that sim works in another phone? What baseband/modem are you on? I am on NAE.
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Yes I tried both nae or Mdc
[Sprint Samsung Galaxy S 4 General] skrapmetal:
Here's what I would do if it were me... standard factory reset. NOTHING left behind, not even internal memory. Do the unlock method again, once done, select modem and fix APN settings. I would even download more than one modem to see which worked best. And do a fresh download of the modems. You could have gotten a partial or bad download.

Here are screenshots of my APN just in case :
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Thanks appreciate it a lot...should I try at modem or regular sprint modems...will keep you posted thanks
[Sprint Samsung Galaxy S 4 General] skrapmetal:
There was a thread with a list of modems and firmware... just don't install firmware, only the modem.

---------- Post added at 10:55 PM ---------- Previous post was at 10:51 PM ----------

Also on step 9 of the original post, make sure you select 'GSM all' last, since you are using gsm. I read that this was causing issues for some people.
[Sprint Samsung Galaxy S 4 General] DaGreatOne671:
Thanks for the help I'll give it a try will follow up with you guys
[Sprint Samsung Galaxy S 4 General] Tekone:
I already have international unlocked and back to NAE modem. Don't see this mention on the OP.. does it need in MDC modem or can be on any modem to setup Domestic unlock ??

Plus.. a Youtube show flash an AOSP rom can be do Domestic unlock instead go thought all this setting.. is that too?
[Sprint Samsung Galaxy S 4 General] skrapmetal:
The original post is outdated. But it needs to be downgraded to MDC to unlock, then you can upgrade to NAE again.

I would unlock on the stock ROM first. Dialer codes sometimes do not work in other ROMs.
[Sprint Samsung Galaxy S 4 General] Tekone:
I think you misunderstand my question... I already have international unlocked. (International unlock require on MDC modem)
[Sprint Samsung Galaxy S 4 General] skrapmetal:
Yes international needs MDC modem. Domestic unlock should be done on mdc also. You can upgrade to nae after you unlock domestically.

MMS Fix

I just found a legit MMS fix and its very simple. I switched back to stock because custom roms dont function properly "can't receive calls/can't hang up"

I was using SlimKat and MMS was working fine, so i did some looking around and i simply just copied SlimKat's apn config file and replaced the stock one and it works perfect! Finally a fix after so much time spent trying to fix it.. lol..

This should be included in the OP :good::good:

Here's the file

http://www38.zippyshare.com/v/74812908/file.html

1. Add to your phone

2. Copy/Move to system/ect/

3. Replace original file

Enjoy :laugh:
[Sprint Samsung Galaxy S 4 General] Tekone:
I went on the step to unlock the Domestic unlock.. Don't know why it froze and without let me go back to main menu on some step. So, i have to reboot the phone, now when I dial *#0011#, I can't access the service menu again. What do have to next to access to service menu again??
[Sprint Samsung Galaxy S 4 General] M1k3Carson1369:
Could someone confirm that this works if they started out on the MK2 (I think, or was it MK3 or MK4. ..?) and downgraded to MDC and unlocked?
[Sprint Samsung Galaxy S 4 General] TheCodexNecro:
Noob needs help

Ok, so I have done all the steps up until 12 and I am having problems. The problem is, my Galaxy won't allow me to turn on my WiFi for some reason. And I'm not sure if this matters but it is also running extremely slow. Sometimes when I try to swipe to get it off the lock screen it won't even work and I have to hit the lock button again and swipe again. Any ideas what I did wrong?
[Sprint Samsung Galaxy S 4 General] malanets1990:
Thank you!

Worked like a charm. Great instructions! Thank you for your hard work!
[Sprint Samsung Galaxy S 4 General] iBowToAndroid:
Yep just did one today. MK2. Downgrade modem ONLY

Factory reset
[Sprint Samsung Galaxy S 4 General] M1k3Carson1369:
I've been having Hella problems with this one on MK2... SEEMS like I end up stuck with either no service, or searching, or sprint, regardless... the times it says no service I've noticed that *#06# displays this:

"IMEI #" , "/" , "L720MEUKMDC" (4 letter between 720 & MDC prolly not the same, just recalling off the top of my head...)....

Anyway, haven't got it to pick up service yet, or get signal even from the Sim, tried AT&T, H2O, and MetroPCS. ...

Are there any steps in the process that differ or vary even slightly from the steps outlined in the OP, If starting on MK2?

Thanks in advance for any and all help and support.
[Sprint Samsung Galaxy S 4 General] aloyellow:
i download the SPH-L720_Rooted_NoData_Restore ND follow all the step when i do the flash it run about 7sec to ABOOT it fail. now the phone is stuck to the Firmware upgrade encounter an issu screen..Please help....

Be patient. Read previous posts concerning this.

---------- Post added at 09:58 AM ---------- Previous post was at 09:58 AM ----------

You're probably on NAE with the MDC modem. Bring the baseband/modem back to NAE (or whatever firmware you're on).

---------- Post added at 10:00 AM ---------- Previous post was at 09:58 AM ----------

Read previous posts. The OP is outdated. You're trying to downgrade the entire firmware (specifically the bootloader) on a secured bootloader.

---------- Post added at 10:01 AM ---------- Previous post was at 10:00 AM ----------

Power off phone. Remove battery. Wait 10 seconds. Put battery back in. Boot phone. Win. This is a issue with Samsung's firmware. I've seen it happen on non-rooted bone stock S4 phones OUT THE BOX. If this still doesn't fix it flash the modem for the Firmware build you're currently on.

---------- Post added at 10:05 AM ---------- Previous post was at 10:01 AM ----------

So there's no IMEI? Someone probably used the Z3X box to clear the EFS (stupid and harmful way to service the L720...z3x is known for GSM servicing, not CDMA). You can use DFS CDMA tool to write the original MEID and IMEI back. As long as it's not blacklisted (check it at checkesnfree.com) it should start working.
[Sprint Samsung Galaxy S 4 General] M1k3Carson1369:
You have to put it into Odin mode [or firmware update error mode, now] and flash either the MDC Modem or the modem to whatever build you were on before trying to flash the MF9 restore.... that that will that will get that will get you that will get you booting again...

---------- Post added at 09:13 AM ---------- Previous post was at 09:12 AM ----------

No, it has the IMEI still, etc... but....

Hang on I'll get a screen shot and attach...

---------- Post added at 09:22 AM ---------- Previous post was at 09:13 AM ----------

But starting at MK2, after downgrading to MDC, is there anything I should do differently than is outlined in OP?

Am not good at this stuff that why i need help
[Sprint Samsung Galaxy S 4 General] droidtom:
I've successfully used this method to get t-mobile to work on my sprint s4. Except I skipped a few unnecessary steps. The steps I skipped is shorter than rewriting what I followed so here goes.

5) I skipped step 5 I didn't go into PREF MODE SET to select GSM_WCDMA_ONLY.

9) On step 9 BAND SELECTION I did the order in reverse so that WCDMA was chosen last.

11) I skipped step 11 entirely hitting WATCHDOG 6 times was unnecessary just REBOOT the phone.

12) using Build.prop editor is not needed I skipped adding the two lines into build.prop and just added the apn settings.

Phone works afterwards might need a reboot and make sure mobile network and roaming is checked as the original posts says to.
