i can tell you dont know much with the technical side when it comes to phones as far as messing with /efs and /nvm

there are no other tools. it is qpst and qxdm

you got something else...hope your not talking dfs

lol

you might be correct on the 2nd point when your taling about coverage and networks (i give ya that) :)

i think in my area tmobile shares coverage with iwireless and they only have edge network and i think gsm (dont know the bands like you do) i lerning that now as i got a couple pages i already had open and was reading starting with the sph-l720 bands it does have in its specs then im going to go look at the coverage available with networks in this area

im somewhat in the country but not in boonies :)
[Sprint Samsung Galaxy S 4 General] imbmiller:
I get what you are saying, you'd like to be able to one click write these settings or restore to these settings using qpst, what I really meant to say was maybe that isn't possible that way because qpst isn't leaked for this chipset. I bet another way to go about it would be to use AT commands in a python script to flip the switches and make the settings how we want them. I've played with dfs, qpst, cdma workshop etc but was always frustrated with the lack of documentation and support for modern chipsets.

I've spent a fair amount of time digging into the world of rex/amss and found very little info as well. The funny thing being that AT commands are from the 80s are still working. Sorry I was snappish, long day driving.
[Sprint Samsung Galaxy S 4 General] en11gma:
well i guess we gonna find out.

earlier when i was in *#0011# i messed some kind of setting up because i can no longer do any ##72786#, ##786# or ##3424#

crap i need ##3424# to put in dm mode so i can restore a backup i made with qpst

im pretty sure it will restore my settings i screwed up in *#0011#

i wasnt fooling around in that area what i was trying to do is do "select" and then "3" at the menu that sticks and i guess it was actually writing to some area when the screen was stuck

frawk

not sure what to do.

i need a real stock rom that actually overwrites those areas when its odined to.

none of the stock roms we flash do that really

got it taken care of

actually flashing a factory rom did wipe that area.

sweet

another thing you right about

yep i was thinking about just setting the settings with qxdm.

there has to be an easier way (prob what you suggested) the people that make roms write their settings there quite often

i mean when "install" from a custom recovery like a tmobile rom like the sprint ones we install they are writing to that area

what is that area?

where are all the default settings? build.prop?

i have seen some in there

So how fast of data speeds are you guys getting?
[Sprint Samsung Galaxy S 4 General] jmb2024:
I'm in Chicago, so I doubt that the spectrum is an issue. I think you may be right about it not working with GSM only. I think my problems stem back to being unable to set SIM CLASS CONTROL to UMTS.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
When I got to that part it said uim class and it was reversed when I clicked gsm it set umts etc. Go through it thoroughly first time I did it I rushed through it
[Sprint Samsung Galaxy S 4 General] pennypimp:
Just wanted to update for any at&t people. I flashed this rom (i9505) and as far as I can tell, everything is working great. The data is nice and fast, mms is working, voicemail...so far so good and I didn't have to do a thing. The rom already had apn for at&t hspa+ so as long as you follow this guide you should be good.
[Sprint Samsung Galaxy S 4 General] imbmiller:
How did you flash it? Edit the zip to remove the version assert or whatever it's called? Just curious...
[Sprint Samsung Galaxy S 4 General] imbmiller:
Glad you got it back, I think that there are carrier specific settings in the build.prop but it only acts as the Android interface, not for the modem interface. I found the differences in build.prop by looking at the cyanogen github and comparing the different jfltexxx models. Chances are that any time you odin a clean stock image all of those modem settings will revert, also if you odin the same Baseband it should reset as well, only when upgrading from mdl to mdc to mf9 will the settings stick. My understanding is that the mja update has a different partition layout which affects the international unlock and thus the domestic unlock, although there are reports of people on mja making it stick. I'm unwilling to try right now because this phone is my daily driver and I don't want to bork it.
[Sprint Samsung Galaxy S 4 General] imbmiller:
In Phoenix I've topped out in the 14mb/s range, in Kansas City I've gotten 6mb/s so I'd say it varies a great deal from area to area. Note that this modem is only capable of a theoretical 21mb/s not the 42mb/s that hspa+ is capable of.
[Sprint Samsung Galaxy S 4 General] en11gma:
i have only used mja since the beginning unless im doing an aosp of course.

the only problem you will have with mja is you will set off knox if you put on a custom recovery

if you worried about knox it will void your warranty but thats about it i think

dont take any OTA updates for sure unless you have 0 on your flash counter and you are stock

the knox counter will always be 1 from here on out and that means you voided your warranty

---------- Post added at 08:57 PM ---------- Previous post was at 08:54 PM ----------

what i want to know is "how do we get our phone number that the sim card is tied to" to show up in settings in phone status?

i ron CM11 and even tmobile roms and they have no trouble

its also the same problem im "sim tool" apps

they are reading the cdma area or something but those other roms read it correctly with no problem
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Because stock touchwiz which I assume that's what's you're talking about is set to read from cdma buried somewhere in code youd have to modify a T-Mobile touchwiz rom
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
you should add that you need root access to edit the build.prop before people start saying they cant

How to update to Android 4.3 After unlocking ???

Guys how to update the phone to Android 4.3 after Unlocking ??? yesterday i tried to OTA update and it got stuck in between and restarted phone...it didn't update anything but when you go to check update it shows the phone is up to date and when you check version it shows 4.2.2... what is the steps to do update ???? Thanks in advance...
[Sprint Samsung Galaxy S 4 General] en11gma:
what setting does tmobile and cm roms use to pass the phone number the sim is tired to the settings about area in the phone?

im sure its just a couple settings we cna do to make it happen right?
[Sprint Samsung Galaxy S 4 General] snekiam:
What modem are you running? I have that rom and am afraid to flash the i9505 modem, and my wifi does not work.
[Sprint Samsung Galaxy S 4 General] pennypimp:
straight-up via recovery. no muss no fuss. it's missing a lot of the bells and whistles, especially with the camera-no modes and such-but it's a nice lean google experience. a lot like my nexus tablet.

so far everything is running nicely.

---------- Post added at 10:31 PM ---------- Previous post was at 09:45 PM ----------

MDC. And for whatever reason I can't understand, it stayed MDC even though I flashed about 5 different roms. Don't ask me why or how because I don't know but every time I looked, it stayed that way.

The thing that got it all rolling for me-and this is AFTER I had taken the 4.3 OTA was this post *HERE*. Just download the tar from the link in that post and flash it using ODIN. I *think* it might be 4.3 but with MDC modem but I can't say that for sure because the first time I flashed it, I went straight away to the international unlock thread and flashed the modem tar (MDC) HERE. Honestly you might want to ask the OP where he obtained that tar (the 4.3) because I think that's the key. It even gets rid of the knox message if you flash via ODIN. The problem is, that did not play nice with trying to get at&t sim working plus I was getting nagged for OTA update and the phone was constantly trying to register on the network. So at first I was trying SACS but no matter what APN I tried I was having issues staying connected and could not get data. Then a tmob rom which was a little better but still same probs and I couldn't send MMS. Finally tried an i9505 rom and it worked like a charm.

.

Bottom line is that anyone who wants this to work on at&t with minimal effort should:

1) flash the 4.3 tar then mdc modem

2) root and install cwm recovery

3) follow instructions in international post then this one with one caveat *it seems* that if you choose gsm all, wcdma all, then lte all when the phone reboots it will stick on LTE so just choose GSM/UTMS in mobile networks if that happens and it should straighten out

4) move i9505 image (look to my previous post on this for the record it's I9505_Omega_v2.0_GUEUBMG8_Android_4.3_md5_830353DC5EB14151A017C340C1285E51) onto phone

5) wipe for new rom

6) install from zip. As I said previously, I didn't even have to mess with APN settings as the rom already chose the correct one

Bottom line is I think as long as you follow the first half you can flash different roms and hopefully you'll find one that works. I don't want to come off sounding like I know anything. All I can say is that I got it to work by doing what I did. As far as updating it and whatnot I'm just happy it's working so I'm done messing with it but like I said it's probably ok to try different roms, you can always go back and flash that 4.3 if you screw everything up and also thanks to nemofbaby2010 because that code (##72786#) for resetting the service menu was key in that I was then able to select UMTS whereas before it was stuck on GSM.

ONE FINAL THING. I have zero interest in using this phone with sprint (I actually gave it to my mom today, she's on at&t) so I wouldn't know if it screws it up for that or not.

Hope that helps. Good luck.

I am not running on the Google Edition rom. That might be my issue, as 4.4.2 does not play nice with mdc modems I guess.
[Sprint Samsung Galaxy S 4 General] tydiamond11:
Any one have and idea on using this phone on vzw i have it working just it says roaming when it is not. It says it is not too.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Thanks to this thread I cut all ties with sprint and joined T-Mobile went from one bar of LTE at home for full h+ pulling 7 mb/s
[Sprint Samsung Galaxy S 4 General] Gambitv01:
i am on stock rom you have the link for the t-mobile rom?
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
I'm using a T-Mobile aosp rom
[Sprint Samsung Galaxy S 4 General] Agarest:
After several days with the unlock, I discovered my mms not working just like others. I am pretty sure it worked initially so I did a bit of messing around. I found out it does work with other messaging apps (I used Textra) but not the native messaging app. Turns out my WiFi blocks the native MMS text. Not sure why since it doesn't block other Texting apps using MMS. If someone knows how I has a fix for this, let me know. Using the native texting app it says: "MMS not supported by network" and "Server response error"
[Sprint Samsung Galaxy S 4 General] imbmiller:
Check your apn settings. Also aosp roms generally will have problems with mms, something wrong with the stack. How do you know wifi is blocking your mms? I use hangouts and have had zero issues so cough up a few more details and let's see what we can figure out.

Rom?

Apn settings ?
[Sprint Samsung Galaxy S 4 General] imbmiller:
You're talking about prl flashing, not unlocking. I would look at Howard forums for that solution.
[Sprint Samsung Galaxy S 4 General] Agarest:
My APN settings are fine, there is no protocol option like others have pointed out. Like I said MMS works when WiFi is OFF. It's simple to test... Turn on/off WiFi and send MMS to yourself, using the native app. I don't see any options on my router that would be blocking this. Also Hangout works for me too but is not the native app. This happens on on two diff roms, one is stock MJA, another on is on rawintellect's Stock(ish) rom (http://xdaforums.com/showthread.php?t=2567353). I left the modems on MDC.

Also I can recieve MMS from other people on my WiFi but it comes as a text giving me a button to Download, but downloading the picture does not work on WiFi. Turning off WiFi let me download the picture. Sending of course does not work on WiFi.

im still on stock rom i get no service with simple mobile sim any ideas?

[Sprint Samsung Galaxy S 4 General] vboyz103:
Just writing to say that I finally dumped Sprint and go with Straight Talk on both of my lines. Will be saving quite a bit in monthly fees.

This is how domestic cell phone services should be, freedom of choice not being locked into 2-yr contracts.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Oh it works perfectly I'm wondering if I could give T-Mobile the imei of this phone because they keep sending me emails

Won't work trying all steps

So I have the sprint GS4. on MDC stock TW rom. Rooted and did the international unlock. Followed all the steps in this post. First I tried it in CDMA and then tried it in GSM mode. Rebooted phone, it would pick up Tmobile for like a second and then it would say X out the bars. Selected network not available. This is an active sim from Tmobile. I also added the APN for Tmobile which it took. It keeps reverting back to network not available. Any clues?
[Sprint Samsung Galaxy S 4 General] Quickvic30:
Got this working on 4.3 MK2 thanks to you guys! I just followed the instructions from a couple pages back (post#279), had to downgrade from MF9 to MDC and all went well. Had to mess around with the network settings but I got H+ working on the ATT network so that's good enough for me. I'll just break out the note 3 if I need the LTE speeds :D
[Sprint Samsung Galaxy S 4 General] george241312:
Dont click UMTS click GSM and it will change to UMTS ... lol dont know why it works that way...
[Sprint Samsung Galaxy S 4 General] aktran9:
Under sim class control I tried both umts and gsm. Also true acquisition order umts_gsm and vice versa. No go. Do you think there is something that is blocking the phone from switching to gsm? When am on cdma mode and connected to sprint, my network status says "samsung". When I do factory reset on mf9 stock, I don't get the sprint bootup animation also. Ideas?

I wonder if editing the eri.xml file has anything to do with this?
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
Any help would be appreciated

This is my first post so please advise me of any mistakes I have made.

I bought a Sprint Galaxy S4 SGH-720. After reading the guide on page one of this thread I decided to unlock my phone. First I reverted the baseband to MDC with the unlock tool. Then I flashed Sacs custom rom 5.4. Finally I followed the region unlock guide here. I am using a T-mobile sim from my previous Galaxy S2. I currently am getting good signal, and have a data connection, however when I try to make a call my phone becomes unresponsive, and the screen flashes. Oddly the call goes through and rings to the precipitant, but no voice can be heard. Txt message works fine, as well as data for browser and apps. Does anyone have any idea what happened?

Thank you so much for the thread, and any help.
[Sprint Samsung Galaxy S 4 General] Quickvic30:
Try flashing a T-Mobile rom and see if that fixes it. I'm running wicked V10 with no problems what so ever. I flashed the modem back to MK2 also and seems to have helped signal strength quite a bit.
[Sprint Samsung Galaxy S 4 General] jaeeee:
i cant find ril.sales_code or ro.csc.sales_code using build prop editor
[Sprint Samsung Galaxy S 4 General] Quickvic30:
Ummmmm you can't find it cause its not there until you add it....you go to the bottom of the build prop and add those two lines to the build prop, then reboot and there will be the option to add new APNs in network settings.
[Sprint Samsung Galaxy S 4 General] kaz007:
So I've done the whole unlock process and it works on t-mobile however data is stuck on edge and will not switch to hspa+ I've reconfirmed and redid the whole process about 6 times but still data is just staying on edge. Is there a way to fix this?
[Sprint Samsung Galaxy S 4 General] comepiedraverde:
+ sign in front of incoming calls.

Hi,

I am sure if this relates to this post, but as I unlocked the phone using this method I hope someone else can help.

I follow the steps listed here to unlock the phone and I am using it with NET10 in USA. My SPH-L720 has a NET10 card in it and I am connected to their network (No LTE, but the internet is still fast enough). I also changed the method listed here to change the phone number listed on settings ##MLS# and enter the number on both fields. :good:

At this point everything works on the phone except for a really annoying detail.

Every call I get (and these are local US calls, not international) has a + (plus sign) at the front.

this is triggering two problems

1- the number shown on the caller id of the incoming call does not always match a number on my phone book. This is a problem as I don't know who is calling.

2- if I dial back, to call the number who called me, the call does not go through.​

Now, if I go to the address book I can call any saved number.

The SIMM card i put on this S4 came from a Galaxy S2, which was working perfectly (not having these issues) - (I had to cut it to make it a micro)

At this point the only solution I have found is to use a program called Prefixer (apk) which will change the first character of every outgoing call to a +1. This of course will force me to edit every number on my phonebook and add the + (as otherwise prefixer will be changing any "first" character into a +1). I do have a lot of numbers :(

I wonder if someone can come up with a solution which does not involve something like this.

I hope the issue is understood, it has taken me three days to explain it to the NET10 team, and all they always asked was if I needed to make an international call (retards) :/

Thanks for all the help.
[Sprint Samsung Galaxy S 4 General] ltindi32:
excellent tuto. I am from PR and I just do that with a sprint galaxy s4, and works with tmobile perfecion. my question is, can I flash it with a custom rom without unlocking me go? galaxy sph-L720
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
The step where it asks you to select gsm all and umts all just select utms all only because when you do all three steps it resets. Also are you in a hspa+,area?
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
Thanks for the reply Quickvic30

Hi,

I am trying this and running into problems, first I can't find a MK2 baseband. I thought I had one, but in cm recovery I get a (status 7) error and installation aborted. Also If I try to update to update to MF9 in Odin I get an auth error:

<ID:0/012> NAND Write Start!!

<ID:0/012> aboot.mbn

<ID:0/012> FAIL! (Auth)

I should mention that I have tied two roms (sacs and CM ) with the same effects, good data but phone goes crazy when call placed. When someone calls me, or I call them the call goes through, but there is no audio and the phone is unresponsive for about 30 seconds.

I will try to flash T-mob rom and get back to you.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Why do u need to go back to mk2?
[Sprint Samsung Galaxy S 4 General] kaz007:
I am in an hspa+ area because I have one phone that works great with hspa+ but when I unlocked this one its stuck on edge. Also where does it ask us to select umts all? I see WCDMA, GSM, and LTE.

[Sprint Samsung Galaxy S 4 General] kaz007:
I got it to work! Thank you so much!
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
I guess I don't need to go back to MK2. Its just that I figured because two different roms had the same issue that it might be my baseband that is having problems. I reflashed to MDC (when I was already on MDC) to see if it would help but I had the same result. Any ideas?
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Did you try just starting over from scratch flash back to stock and redo the steps all over again?
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
I would love to, how the heck can I get back to stock? Flash Rom/baseband? Also any way to reset the settings in *#0011#? Maybe I messed one up that shouldn't have been changed.

I just tried wicked v10 with same results.

##72786# on any sprint touchwiz rom
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
22595335

I am trying to flash back to stock and have run into the following problem:

In Philz recovery I choose install from zip, choose the rom, and then I recieve the following error:

This package is for "jfltespr" devices; this is a "jfltexx".

What I could find on google said the "jfltexx" is a "Samsung Galaxy S4 (Intl) - jfltexx" SPH-I9505

My model number on the back of the case says SPH-L720.

Any ideas?

*UPDATE*

used "android model changer" from the app store to try and change the model name, but it says it is already a "jfltespr"
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
What rom you trying to flash? Flash sacs ROM if that fail just Odin back to stock
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
I don't even know where to start with this, BUT, I got it working. This may or may not be helpful to anyone but I'll post it here for the sake of trying to improve the community that helped me.

If your SPH-L720 starts with the MK2 modem, you will have trouble or be unable to flash a rom lower than 4.3 (thats what happened to me)

I fixed my issue by putting a stock rom 4.3 and a new MK2 modem. The wifi would not work after that so I then upgraded to SAC's custom rom. I am now up and working on T-Mobile

Thank you all for the help.
