selected network not available with lock

Hoping someone can chime in.

I have 3 sprint SG4 phones. 2 of them I have already unlocked internationally and domestic unlock using the steps at the beginning of this thread. The last sprint GS4 has been a struggle. I'm on stock MF9 and downraded modem to MDC. Successfully unlocked for international use. However, I went through the domestic unlock and all I get is a a circle over the signal bar and cannot register on selected network. I have tried with nonactivated Tmobile sim and activated tmobile sim. Have tried changing UTMS to GSM and vice versa. What other steps can I do? I have also tried in CDMA mode to get into the service menu and also GSM mode. No dice. Is there something in the phone that is not allowing the phone to register? This is an unactivated phone; meaning it's not activated to sprint. I am currently on Pageplus. For historical purposes, my two other unlocks were done while being active on pageplus and ringplus. I would donate to anyone who can help.

Dropped calls like crazy

So after a days use I have found that almost every call I make drops within 5 minutes. Sometimes the audio is all fuzzy. I live in New Orleans so I know towers aren't an issue. Anybody have any ideas?
[Sprint Samsung Galaxy S 4 General] Loqheed:
Flashed back to MDC, then to MK2 then to MF9

I was able to successfully unlock my phone and get it working on HSPA+ and set to WCDMA only. When set to GSM/UMTS, I can still get HSPA+ but it's intermittent and I switch back and forth while staying in the same area. The problem with WCDMA only is that I've noticed that data will get disconnected periodically and it's getting really annoying.

I've checked all the settings and they have remained the same as described in the original thread (and I selected WCDMA all because I do believe that's an error in the directions as mentioned previously). So while I'm getting decent speeds on HSPA+ (anywhere from 1meg to 8megs), the dropping of data is driving me nuts. I had flashed from MDC -> MK2 then downgraded back to MDC and then settled on MF9. I also flashed a tmobile rom. I've had to deal with similar issues in all cases.

Is anyone else having this problem?
[Sprint Samsung Galaxy S 4 General] jaeeee:
why do we need to add those two lines in build.prop my hspa+ is working perfectly without adding them
[Sprint Samsung Galaxy S 4 General] Quickvic30:
So you can add different APN settings for different carriers/netwroks. What carrier are you running? Is your MMS working?
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
If you guys are looking for a ROM I've been using T-Mobile Google play edition KitKat Roms without problems
[Sprint Samsung Galaxy S 4 General] jaeeee:
I am running tmobile and yes everything is working perfectly fine I can add diferent apns and everything thats why I was asking myself why I needed to do that part
[Sprint Samsung Galaxy S 4 General] vgomez916:
How do you revert back to sprint settings. If I want to use just use my tmoblie sim sometimes.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Some Roms Dont allow you to change apns, I think stock allows you to change it, and sacs didn't let me change it
[Sprint Samsung Galaxy S 4 General] Quickvic30:
What ROM are you using?
[Sprint Samsung Galaxy S 4 General] jaeeee:
I am currently running 4.3 sprint mk2 stock rom and I am rooted
[Sprint Samsung Galaxy S 4 General] gibrannz:
oh man i just updated to MJA 4.3 last week,

do you think this will work?

it lets me change and add new APN when non-sprint sim cards are inserted.

i don't get any "invalid sim card" errors, i tried using a t-mobile and a telcel sim card from mexico.

but when it starts searching for networks nothing comes up.
[Sprint Samsung Galaxy S 4 General] imbmiller:
I'm not sure, I'd try to get into the diag menu and change the options I listed. My guide is based on downgrading to mdc to do an international unlock tho so your guess is as good as mine.
[Sprint Samsung Galaxy S 4 General] imbmiller:
Hmm, I waited to reply because I wanted to test my speeds throughout the day but I am consistently getting 9-12mb down. I'm using sacs rom Idk if that would make a difference tho.
[Sprint Samsung Galaxy S 4 General] sjc915:
I did this last night and it worked great. This phone is now working on AT&T. The only issue I am having is that on any 4.3 rom I loose the ability to change my voicemail number becuase it becomse manages by sprint voicemail... anyone know a workaround, works fin in the stock rom Settings--->Call-->Voicemail Settings. Also in the device information the phone number still shows as the old Sprint number as does the sim card on any sim reader app I use, any Ideas? Thanks.
[Sprint Samsung Galaxy S 4 General] laoh:
Give YouMail a try. There was a time I was switching back and forth between Touchwiz and custom ROM and with custom ROM, the default voice mail app isn't there. So I tied Sprint VM to YouMail app and installed it on both Touchwiz and custom ROM so it didn't really matter which I was running. You can try doing the same - tie a 3rd party VM app to your ATT VM.
[Sprint Samsung Galaxy S 4 General] imbmiller:
My device shows the old sprint number as well but it doesn't actually use it. I'm guessing it's reading it out of the prl or something other than the sim but I've never worried about it.
[Sprint Samsung Galaxy S 4 General] doctorman:
Step 8 I don't have GFC I have GCF

Step 13 I do not see WCDMA

Android Setting> Connections> More Networks>Mobile Networks> Network Mode:

CDMA

LTE/CDMA

GSM/UMTS

Automatic

mine was on nothing! so I changed it to GSM/UTMS

I do not see WCDMA?

Can some one explain please

Under Roaming settings:

it is all grayed out and untouchable beside the last one GSM networks > Data

Finally can you switch back to MF9 baseband after all the playing arround or did you guys keep MDC?
[Sprint Samsung Galaxy S 4 General] imbmiller:
Step 8 is a typo.

Step thirteen, gsm/umts should be fine, if not try automatic.

As long as you activate gsm data it should be fine.

I kept mdc. I needed a break from working on this phone.
[Sprint Samsung Galaxy S 4 General] doctorman:
1) I figured out why yours shows WCDMA

Depending which Band you do last that is the one that shows from step "9) Press menu and back and select [2] BAND SELECTION"

so If I do WCDMA last that is the one that shows...

If I do GSM last GSM will show..

Regardless I just change it to UTMS GSM..

Not sure what WCDMA is .. I thought CDMA is only in USA

2) I used this APN and your HiAPN solution together

http://xdaforums.com/showpost.php?p=45197063&postcount=202

I did that and then HiAPN asked to overwrite I chose to keep it.

3) the roaming

- Roaming network (select roaming network) is grayed out

- Roaming setting are all grayed out but GSM -Data (checked it)

-Roaming gaurd - all grayed out but GSM ( I unchecked it)

that must be the norm I tried it on 3 phones, so I am not worried.

4) How can I stop the automatic MJA software download. nagging at me..

Disable OTA updates for L720 ?

I am using a Not activated Tmobile Sim to test it.

It find AT&T and Tmobile Networks when I search , connects to tmobile and shows HSPA .

Thank you very much for this AWESOME post!

Now lets see if anyone had the courage and upgrade the baseband to MF9 after and see if that effects anything..

and lets find a way to avoid that OTA nag for MJA
[Sprint Samsung Galaxy S 4 General] hector123456789:
made it work

I tried this method and it failed....

I did it another way and know it works!!!!! here is what I did.

1) follow step 1 on this post

2) followed the

complete

process on galaxys4root.com sprint carrier unlock.

3) dial *#0011#, once in service screen PRESS,,MENU,,,,,BACK,,,,,MENU,,,,,,KEY INPUT,,,,1

4) once that is done follow steps 5-13 on this post.

5) im in florida my network mode is set on:GSM/UMTS everything works no more unknown sim issues and im running on tmobiles service ...

it was a pain but I got it done ....hope this helps someone.
[Sprint Samsung Galaxy S 4 General] imbmiller:
ok

1) You are correct, I went back into the android settings I hadn't selected anything either. It was set in WCDMA only as a result of our actions in the debug menu. WCDMA/UMTS is essentially the voice service that the GSM operators us. I changed it in the guide as not to confuse.

2) I didn't have any trouble with hiapn working right away when I used it but there is no problem adding the apn manually, I was just trying to simplify for more basic users.

3) thats perfect, I'll clarify the guide so that no one worries.

4)I read somewhere that if you went into the google services method it should work but you have to delete the update out of the folder it is stored on your phone at the same time....IDK where it is located but I have seen it on this board somewhere.

5) The International unlock should be safe and the one time i rewrote the modem with identical MDC modem it saved all my setting changes. Not sure for MD9 and the domestic unlock. As soon as there is a downgrade option available for MJA i'll upgrade. I'm also working on a one click solution similar to the International unlock method.

So you actually did step 1-13 . that guide is based on the guide that I gave you in step two except the link I gave was easier to complete. The method that you used to to get into the diag menu is what I meant by the app works like a tin can radio, I could never replicate the way i got in it was always a random set of menu, back, input key, select, menu back etc etc etc. I'm glad you got it unlocked though.
[Sprint Samsung Galaxy S 4 General] doctorman:
They changed the folder the downloaded file is kept... I could not find it.. if anyone has any info on this there is 10,000$ reward offered for its head.

--------------

the service menu *#0011# worked everytime and it is not random at all

again experience from using it on 3 phones

*#0011#

Menue>Back

Menue> Select > 1

the 1 should show as registered on the screen.. wait couple of Seconds and you are in the menu

Menue>Back

and you can chose between CDMA or UTMS etc

==========

Honestly your guide was very clear and works! Thanks again.

MDC upgrade to MF9 baseband should be okay then? it is just the MJA we don;t know about
[Sprint Samsung Galaxy S 4 General] gibrannz:
i tried to do that. now my phone will not get any internet? not 3g, lte or anything. just voice and sms.

i noticed service mode menu says "no service" please help
[Sprint Samsung Galaxy S 4 General] the.joeba:
I updated to MF9 and lost signal (after changing to CDMA and then back to WCDMA), so I've reverted back to MCD. I'm not running SACS v8 and I went through the steps again.

One thing I found odd, when I'm on [3]NAS Control/[3] SIM CLASS CONTROL, if I click UMTS it enables GSM, band if I click GSM it enables UMTS. So I end up clicking GSM so UMTS is the one 'selected'.

I seem to have slightly better HSPA+ signal, but the speed hasn't gone over 1mb. Still a bit bummed about that. I'm trying to get a Nexus One working so I can compare it side by side (Nexus One is kinda bricked).
[Sprint Samsung Galaxy S 4 General] the.joeba:
I noticed that when I select any of the nested settings in Band Selection, only the last chosen option gets a *, so if LTE ALL is selected, LTE/LTE ALL each get a *

I've made sure WCDMA ALL was my last selected, and I seem to be staying on HSPA+ instead of being switched to Edge constantly.
[Sprint Samsung Galaxy S 4 General] imbmiller:
Awesome, have your speeds increased a well? I had a thought hat you could narrow the bands to your specific freq Fo hspa+ in your area nd maybe that would improve the speed.
[Sprint Samsung Galaxy S 4 General] the.joeba:
I don't have the HSPA+ Speeds that others have (even co-workers), but it's better then what I had with Sprint. It's pretty strange that my co-worker gets 5mb/s and I get 1mb/s. If I get my Nexus One working I might be able to determine if it's my device or something with my account.
[Sprint Samsung Galaxy S 4 General] imbmiller:
I always thought it was in the cache folder somewhere, however that folders contents are hidden by default.

Mf9 is solid according to nicotheandroidguy. And hopefully we can know more soon about mja.
[Sprint Samsung Galaxy S 4 General] imbmiller:
That's a pretty sad report for sprint when broken tmobile sig is stronger than their functioning sig. You should compare the signal strength in decibels that you get vs. Your Co workers. If I remember correctly that telinfo app showed those signals. What area are you in?
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
That's why you Dont need to add it stock allows changes to apn
[Sprint Samsung Galaxy S 4 General] jaeeee:
oh alright thanks for answering my question, im on tmobile and its way faster than sprint im getting 9mbps in Chicago
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
I though Chicago had good sprint data speeds
[Sprint Samsung Galaxy S 4 General] jusinjusin:
Has anyone else been getting fuzzy audio when making a phone call?
[Sprint Samsung Galaxy S 4 General] jaeeee:
I used to get like 5-8 mbps on sprint but now on tmobile I get 7-10mbs
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
You using a stock ROM?
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
I have tried stock, and many non stock roms, and different basebands. This leads me to believe that the problem is with the service menu settings, or my handset itself. ( I bought it used and don't know if it worked right before hand ). However being the third person to report this kind of behavior on this thread I am inclined to believe that my headset is fine. I will keep searching for a fix but I don't know very much about settings or anything else and have to rely on other peoples post. If I stumble across a fix I will write about it in detail.
[Sprint Samsung Galaxy S 4 General] vgomez916:
Question if I had sprint already unlock my sim on my s4 do I still need to do all the steps to get tmoblie working.
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
I had an issue like that but it was because I was using kt kernel and it was acting weird disabled it, and it went away
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:
How can I check if I am running kt kernal? and disable it if I am.
[Sprint Samsung Galaxy S 4 General] Quickvic30:
Go into the settings menu, then more, about device and you will see kernel version near the bottom. I'm running the KT kernel but I deleted the KT tweaker APK that flashes with the kernel I believe,s trickster mod is a much better kernel control app IMHO. I haven't had any issues with sound or dropped calls. Once and a while Data will be kind of slow but it never looses connection.
[Sprint Samsung Galaxy S 4 General] jusinjusin:
I was, but I'm currently using the Hyperdrive ROM from the T-Mobile forums. Thinking of ODIN'ing back to MJA stock, and then the MDC modem this weekend.

Ahh I see, I'd like to try this out! What thread should I be reading to change up that KT tweaker?
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
everytime i would open ktweaker it would say values do not match so idk that may be your issue
[Sprint Samsung Galaxy S 4 General] Quickvic30:
Just go to the play store and search trickster mod and install the app. Or search on here and I'm sure theres a thread on it somewhere :good:
[Sprint Samsung Galaxy S 4 General] levirporter@gmail.com:

any way to full restore and keep the unlocks?

Thank you for this OP, i thought i was screwed when i bought a S$ and found out it had a bad ESN till i found this thread. So my phone is rooted from the previous owner and im not sure whats on my phone but basically all my internal sd was full with files he put on. I want to somehow do a full restore and unroot but i did the international and domestic unlock method yesterday. is there a way for me to full restore and not lose the international and domestic unlock then root it myself? thanks guys
[Sprint Samsung Galaxy S 4 General] nemofbaby2010:
Go into the recovery wipe data/factory restore. Then mounts and storage earase SD and external SD card
[Sprint Samsung Galaxy S 4 General] jcm707:
Thanks nemofbaby but will I keep the international and domestic unlock or have to do it all over again?

You'd only lose it if Odin back to stock or use ##72786#

Wifi Broke during the process

First, thank you for posting this -- I know it takes a ton of time which we don't have in life

I bought this S4 and I am a real newbie to Androids in general so all help is appreciated

I'm having the following issues:

I first followed the Step 2 Guide because I didnt know what I was doing. I completed it and have the MDC Baseband version installed. I tried to revert the rom to a stock MF9 from Step 1 and it fails every time. Since it fails, I reflashed to MDC and it then reboots the phone to the dashboard.

I followed the rest of the guide only until step 12 -- WIFI Does not turn on anymore and I've done a factory reset and still cannot figure this out. It ironically picks up the SIM card as t-mobile and can make/receive but when a call is made or received the phone app freezes so it basically doesn't work (as I would expect).

I want to get this done right... can someone explain how to either get WIFI to work again or how to revert to MF9 or what I can do to fix this?

Please and Thank you --

Flash sacs rom

Is there multiple versions of SACS rom? Where can I get the right version?
[Sprint Samsung Galaxy S 4 General] dimm0k:
is there any way to verify that my device is unlocked domestically without a non-Sprint SIM card installed?
[Sprint Samsung Galaxy S 4 General] ffr0zen:
After step 11, I was able to get tmobile calls, no data and no wifi

Went crazy and was helped to flash my phone back to MK2, now I get tmobile service but no data

Moved on to Step 12 and installed both apps but could only get the build.prop editors to add the 2 line and there is no clear way to create a shortcut on the home screen

Now, the phone is no longer rooted and sacs rom looks like its gone after this MK2 PDA flash... I have no idea what to do

Does someone have a sec to help?

Most appreciated --

[Sprint Samsung Galaxy S 4 General] ffr0zen:
Hey everyone, so the issue I am having now is I cannot get mobile data to work.

I've done the following:

Downgraded to MDC, Rooted w/ SACS and followed this guide partially

Awesome, wifi didnt work though. Someone told me to follow THIS guide http://xdaforums.com/show....php?t=2601443 because I had KNOX bootloader, so I basically updated to MK2.

No more SACS or ROOTed system, but Tmobile still works... awesome.

Now data..... I am trying desperately to get this to work but having a ton of troubles. I cannot use the *#0011# method as it brings up some information, but I cannot get it back to the menu

The original guide says to use prop editor and add a line, but the thread doesn't explain it well. I am googlin it now and can't find out how to get this part done.

Please and Thank you -

[Sprint Samsung Galaxy S 4 General] en11gma:
i have a few questions.

the first is about both the us cellular galaxy note 3 and a sprint galaxy s4 both factory default settings.

01 are they set to RUIM_Only or NV_Only by default the way they come out of the box brand new?

the sprint GS4 had the msl set to 000000 which is pretty standard for buying any unlocked phone to my understanding which this phone was not standard like that but the msl does = 000000 now and it is sprint branded and meid is recognized in their system

we try to activate and it does just fine but we are getting pop ups and it keeps locking the damn sim card "the sim card is locked" or something like that

at first they did say it was bad sim card but it happened when we switched out sim cards with another one

i got a hold of "advanced tech support" and they said if the phone was every used on another non sprint network then the phone will not work with sprint again.

this is not true as the phone is activated and working just fine but we have to keep the phone in "CDMA" only mode and NO sim inserted

but the phone works ok just no 4g lte

i cant believe a phone would be partially activated or partially allowed on the network so i am wondering maybe i did something wrong when i flashed it

i was in ##3283# and dfs alot and maybe i have some setting screwed up.

any help on this would be great as the phone is no longer mine but the guy who got it sure would like to have it working correctly

there is no 4g/lte here in this city from sprint anyhow but his wife has her sprint s4 in cdma/lte network mode with sim in and hers does not do this.

02 uscc note 3 16 digit password does not work. anyone have a new one? i on mk2 on it also

thanks

just wanted to add we have done serveral activations through sprint and i have done ##72786# and ##786# several times also.
