[Q] Help needed, no cell service 4g works - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hi guys,
I messed up my gf's s4 last night. Was previously using sacs custom on a mf9 base (unlocked, twrp) Tried updating to Aokp so she could use her new G watch. I was messing with the radio settings after flashing aokp for whatever reason, using Radio Switcher from the market, and now the phone no longer has service. 4g works for whatever reason but no 3g, calls or texts come through. Tried one click odin back to stock mf9 in hopes it would work, but no cigar. Any help guys?
Thanks

Mods please close, ##72786# from the stock dialer fixed the issue.

[Q] Omega ROM on I337M

I successfully flashed i9505 Omega ROM v7 on I337M (Canadian)
Everyhing works fine but the wifi. I can't seem to turn my wifi on.
Tried looking into it, something about flashing a kernel. So I tried but doesn't work...
Anybody else have same problem that can help me?
Did you manually add in your apn settings, because that rom does not add them automatically, and you said you flashed a different kernel, was it one for YOUR device...i337m kernel?
These 2 things will get you data and wifi for sure.
The Ax says good luck!
v11 on i337m
I didn't want to start a new topic as this one seems to be titled correctly and am hoping to keep XDA clean and getting all the Omega Rom and i337m questions in one place.
I installed Omega v11 on my i337m (Samsung s4) and the ROM worked perfectly however I was no longer able to bring up my IMEI number. When entering *#06# my phone would just show a black screen where the number should be shown. I of course got scared and ran around in circles for a while before calming down and flashing stock FIDO firmware. (phone was originally rogers, was unlocked and used on bell then sold to me) I rooted the phone, installed Omega and then had the issue with it not being able to show the IMEI.
Flashed Omega v11 for i9095
(also bought the omega files pro app because it's a bad ass ROM.) Hoping to go back to it but need to clear up this issue.
Any ideas on why this would happen?

Service Search Issue *Solved

I have recently updated my 1337m from Bell from 4.2.2 to 4.3 darthstalker and I am having a weird issue. When I turn on my phone screen I lose my reception and it searches for it again. Sometimes it will find it instantly other times not at all. If I go to search for networks and then hit back while it is searching it will find my provider, bell. If I lock my phone while I have reception my phone will continue to get reception and I can receive calls in text but if I lock it without reception I do not get reception.
I also tried flashing to 4.3 hyperdrive rl12 but the same thing occurs. I also have uses the kernal that came with darthstalker ROM and ktoonz most recent kernel and again I get the same issues.
Sorry I've searched for this issue and could find anything. If you need any more info please let me know.
Thanks,

*Solved. I was using the 4.2.2 baseband. When I updated the baseband it fixed the issue.

[Q] i have a question and i'm confused.. plz help me

ok here it is. i've flashed various roms but don't really know what everything is, i just followed all those insturctions but never bricked my device..
I live in China, use 3g mobile internet, my phone is korean note2(shv-e250l), use slimkat 4.4.2 nightly, bandwidth MI1, kernel thor 2.9.
i've been using these for about 1 month, and there was not any big problems, except that it feels like my signal strength or internet speed isn't as good as stock rom
but yesterday, when I hung up after calling my friend, all of sudden my phone can't read my sim card, so i reboot the device, and my mobile network doesn't work, and i reboot again, finally everything works.
after that, everytime i call someone my phone goes stupid and i have to reboot it twice.
and I started to wonder, does my bandwidth need to be updated? can I use newest stock rom's bandwidth?
newest stock rom of korean note2 is NA1, will using its bandwidth solve my problem?
if it does the magic, how do i apply bandwidth of NA1 to my phone?
HELP ME.............

Help No Service

Hello everyone,
I'm getting no service on my Sprint Galaxy S4 SPH-L720.
I've tried Slimkat 4.4.2, 5.0.1 and Google Play 5.0.1. I get service at times but it keeps cutting out for no reason. I am on baseband L720VPUFNAE, and PRL version 55020. I'm using an app called Roam Control which keeps the phone on roaming mode but it won't stay connected either. Even when set to force roaming it trys to connect to Sprint service. Perviously it would stay connected to Verizon.
Also on Slimkat 5.0.1 when enabling Roam Control it says "please make sure device is rooted" I know it is, because roam control doesn't give me that error on Slimkat 4.4.2 or Google Play Edition 5.0.1
I started having these issues about a week ago, before that everything was working fine. I was on Google Play Edition for a week, and then I started having these issues and went back to slimkat which worked flawlessly.
So to summarize this, phone will not stay connected to roaming no matter what I do. It wants to go back to Sprint, I've tried calling the ##872283# number or whatever it is. That didn't work, it told me it was unavailable and to try again.
Also, one time my cat knocked my phone off the table and it said no sim card inserted so I rebooted my phone and have been having issues since that day.
Did you check to make sure the SIM card didn't get jarred loose when it fell. If that's not it do you have a backup of your stock Rom you could restore? I have had connection problems before and going back to stock TW Rom restored it.
Hi, thanks for replying
I removed the sim card and put it back in, but that isn't fixing it.
I'm on GPE 5.0.1 latest update. Sometimes Roam Control works, and my phone will stay on roaming network, and sometimes it won't. Whenever I go to switch between Home and Roaming it doesn't want to go back to roaming. I have no idea what's going on.
Hi again,
So this is what i've noticed so far.
Slimkat 4.4.4 = Confirmed working, phone goes in and out of roaming back to Sprint network just fine. All data/mms works perfectly.
Slimkat 4.4.2 = Confirmed working, phone goes in and out of roaming back to Sprint network just fine. All data/mms works perfectly.
GooglePlayEdition 5.0.1 = Phone has intermediate service
Sacs Custom Rom v4 = Phone has no wifi, but the Roam Control works.
Slimkat 5.0.1 (Beta/Alpha) = Phone tells me it isn't rooted.
So the good news is, i've got the phone to be atleast usable now. But I want to know why these other roms are giving me problems, is it the baseband/modem I am using? Which one's am I supposed to be using for these roms?
From what I've read here on xda you have to be on the latest firmware, NG2 to have any success getting lollipop working smoothly. So I would look up how to use Odin to upgrade that. All the rooms that I've flashed recently have mentioned in the op to be sure you're on the latest firmware so it may also help with the other KK rooms.
I'm on Baseband version L720VPUFNAE isn't that the latest one?
No NAE is more than a year old NG2 was released last summer.
Hi,
I went ahead and updated to NG2 baseband using this file http://www.androidfilehost.com/?fid=23622183712458249 and Odin. (I am stating this to help people who might be Googling). It updated my Modem from the NAE one to the NG2 baseband, I am still on Slimkat 4.4.4. I will try flashing Google Play Edition 5.0.1 and see what happens.
Thank you guys for the assistance!
Does everything work the way it should on SK 444? If so make a backup so you have a solid place to revert to if you need it in the future. Also be sure to get a good GPS lock before flashing to a 5.0 Rom.
Yes everything works in Slimkat 4.4.4. The phone goes in and out of roaming without any hiccups. Also what do you mean by make sure you get a good GPS lock?
Furthermore, I have went back to Google Play Edition 5.0.1 and I am still experiencing the issue where my phone does not want to go back to roaming after being on the Sprint network. I will be out of service and the phone will just say "searching for service" even though I have Roam Control set too "Roam Only Mode". In order to get my phone to get service back I have to go into Cellular network settings and select System select and put my phone on Home only and then go back to Automatic to make the phone connect to the roaming network.
This is becoming a real nightmare.
The GPS not working was a common problem with GPS 5.x and having a good lock on your position in a stick TW Rom before flashing to GPE is supposed to fix it. So my comment was merely a preventive one. I have no idea for you on the roaming problem in GPE.

Have you tried updating the profile and prl while in SK 444? Then flash into GPE, that's one thing I would try if you haven't done so.

How would I go about updating the profile and PRL while in SK 444? It's based off of Cyanogenmod kernal, as is GPE.

You must be on a stock touchwiz rom in order to update your data profile or prl.

My bad, I meant have you tried updating the prl and profile while in a stock TW rom? My apology for the confusion.
Here's another thought, perhaps try one of the other non GPE 5.x Roms to see if your troubles are limited to the one GPE Rom or if it's a lollipop issue. That may be useful info for those smarter than I to help you work this out.

I may be having a related issue. I didn't want to make a separate thread in case this is the case.
My data was just fine about a week ago. Then I decided I'd try out a new ROM because there's a couple things that annoy me with CM12 at the moment, so I tried the GPE ROM. It was all great except I wasn't getting service when I'm at work.
The problem is that this is now the case with EVERY ROM I flash. I also tried nandroid restoring what I had before flashing GPE. I even went back to stock, did the whole PRL and Profile thing, but I still have no service.
What's also a problem is that I have service (LTE) at home, so whenever I get home to try a new thing that will hopefully fix the issue, I can't find out til I go back to work or leave home or whatever. So far, every day has been unsuccessful.
Edit: A weird thing is that even where I have LTE, if I go to view my network status, it shows "Out of service" under Service State, and Mobile Network State as disconnected. Actually just noticed this, but my phone number is 0.
Alright, so further testing has commenced.
I went over to a Touchwiz rom, updated my PRL, activated the phone, and did all of that. Went back to SlimKat 4.4.4 and thought my phone was on "Roam Only". Well turns out I was wrong, the phone is set to Roam Only and I am still trying to connect to Sprint towers while at home (Where I have no Sprint service) so something definately up. Maybe I need to re-root my phone as I am having some weird issues when it comes to root. Can someone perhaps link me to a thread to get started on rooting the device? I don't remember how I did it last year when I bought the phone. But I am comfortable with using Odin and SamsungKey drivers.

i9505 i337m canada mobile network connectivity

Hello All,
I have a samsung galaxy s4 i337m in canada using the rogers netowork. Ive been using customs roms shortly after i got this phone. Ive used samsung rom, original, GPE but eventually settled on Cyanogenmod. I use TWRP for the i9505 which allows me to use any rom (since CM12 doesnt have a build for the i337m, and other builds wont flash in a i337m TWRP).
Anyway ive been using CM 12.1 with a i9505 build for some time, and it works great. I had to update my modem to the NI2 build to get it to work, but its been working flawless ever since.
Now to my problem, buddy has an S4, same model, same carrier. He claims he needs a new phone and i beg to differ. I rooted, installed twrp (i9505)and cm12.1 (i9505). works great, however no network connectivity. I remember i need a new modem, try the same one that works with mine....nothing... try a different one.... nothing. calls and SMS, but not data of any speed.
Reverting to kitkat roms results in it working perfectly (multiple modems). both from his original Nandroid and CM 11. All lollipop roms seems to have the same issue, no mobile data. Wifi works fine. No issues with SIM card, switched them between the two phones and confirmed its HIS phone with the issue.
Im a little puzzled, can someone recommend a modem to load? should I try to use TWRP an CM12 for the ATT variant/ different variant? I want to help him but this is making me look amateur (even if its true).
Thanks ahead of time.
