mobile network is unavailable after custom ROM install. - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello Guys,
I bought an S4 and I discovered that I was scammed (it was the sprint version and not the GT-I9500 as it was indicated on my about phone tab). It comes with 4.4.2 and everything was working fine (the only things that bugs me was that I was unable to receive updates). Recently I encountered some little issues so I decided to install a new ROM. I tried the Vanir and Commotio ROM and for a moment I was super satisfied (it was an amazing experience). However after putting back my SIM card, each time I try to deal a call, I got the error "mobile network is unavailable". I thought it was an issue from the ROM I used so I tested the LineageOS and same issue. Finally I tested the STOCK ROM Lollipop and the same issue again except this time the WiFi does not work. Now my phone is completely useless, so can anyone help please ?
PS: When I go to settings->about->status, everything about the SIM info(network, my phone number,...) is set to unknown. the IMEI is intact (non null). IMEISV is 00.

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.

Dialer problem!

Hey guys! I got my note 4 today. It is used.
It came at 4.4.4 android version and rooted. So i installed TWRP and flashed BLISS Rom.
But right after i dial any number, i got "call ended", i cant receive calls and sms too.
I already tried another SIM card, but the problem persist.
I also updated the bootloader and the modem to the 6.0.1 version from the ditto note 5 rom topic.
What else can I do to make it work ?
Did i got and defective phone ?
Is the SIM card you are using only works under 4G area? Or does it support 2G/GSM as well?
Try reinstalling the stock firmware and see if that helps. But don't root it this time.
Yes, it supports 4g. And i already tried the stock rom, but with no results... What can i do ? D:
APN settings correct for your carrier?

G900P in Europe?

Hi!
I've bought a Galaxy S5 (G900P) from Ebay last year, but I wasn't aware that the Sprint variant is meant for the US. (just realized that now, since I ran into problems). I've used it for almost a year now, running Android 5.1.1 with Cyanogenmod custom ROM on it - here comes the thing - as G900F. (which I just realized aswell, thinking back, and checking screenshots / Windows logs). The About Phone section, the usb drivers in Windows, several other things claimed it was G900F firmware on it - and I was able to use 3g mobile internet on it, was connected to Vodafone Hungary without problems. (turns out I can't use 4g in Europe with this variant, that's my bad). The Recovery mode (used Phil'z) and the Download mode both displayed G900P..I'm not sure what to think now.
The problems started when a few days back, Cyanogenmod announced the 13rd version, and my auto-update on CM12 took its curse, and updated it. The whole thing went smooth, phone rebooted, and instantly got hotter and hotter, draining the battery seriously fast. I've tried several apps, methods, none could help it, so I decided to just stick with Android 6.0.1 (since it came with the CM13).
Through 2 days of suffering and reading forums, pages till my eyes bled out, I managed to have a stock G900P 6.0.1. Android on my phone, it's currently charging, but here comes the fun, I'm not able to get mobile internet (3g). I could connect to Vodafone Hungary somehow, calling, and receiving calls, but there are several other things wrong with the phone like this. I've also tried to revert back to 5.1.1 (even the Stock ROM would be fine, I'd gladly skip on CM12), but Odin failed and failed each and every time.
So my question is: I know it's possible, because I DID have it, but I don't know how to anymore - G900F firmware on a G900P phone. Any help would be greatly appreciated.
(current status - Android 6.0.1 with stock G900P firmware - unrooted / I think/ ; without custom recovery, in Download mode both things say Official)
P.S.: if this subforum isn't the place for a thread like this, I'm asking a mod to please move it to a rightful section, thank you!

Huge Problem, Cyanogen 14.0 - SIM not detected

Okay, I should of just stayed here to say first...
I decided to flash cyanogen on my s4 due to bad battery life on the default sprint. I am using Tello as my provider and it was fine on stock firmware, however, I installed this galaxy-s4-sprint-cm14-cyanogenmod-14-nougat-rom from cyanogenmods dot org
Right after installing, as I got in, it said sim card not detected. I have no cellular signal
Is there anyway to fix this?
Please help and thanks!

Delayed Texts and Unknown Carrier with Custom ROMs (7.1.2 / 8.1) on Verizon S5-G900V

So I have posted before without any replies and am still seeking help...
I know there are others out there in the same situation as me:
On an Unlocked VZW bootloader
On Verizon Wireless 4G LTE in the US
Trying to run a Custom ROM on their phone
But for some reason, I seem to be the only one who has a random delayed texts (both SMS and MMS) issue (by 1-15 minutes) on these forums. Sometimes on Custom ROMs the texts come in normally but other times there is a long delay and it makes having a conversation with people very difficult and irritating. There is NO text delay on rooted (Magisk) QL1, the latest Samsung stock TW S5 6.0.1 ROM, and I have gone back to it since I have no more ideas left to try.
What I have tried:
AEX 5.8 (Oreo 8.1), Havoc OS (8.1), Lineage 15.1 (Latest 8.1), crDroid 3.8.5 (7.1.2), MoKee (7.1.2), AOKP (7.1.2)
Changing APN settings to include the MMSC http://mms.vtext.com/servlets/mms and leave blank which is the default on Custom/Stock ROMs
Changing APN settings to match the stock VZW settings exactly
Flashed new VZW APN files from an ltefix.zip file I found on XDA
Changing CDMA to be Home and not just Automatic
Changing from Global to CDMA/LTE+EVDO
Went to the Verizon store and got a new SIM card
Booted up without SIM and powered off; then inserted SIM and booted up again
Tried different Modem/Non-HLOS versions like QC2 and QL1
Went into the secret *#*#4636#*#* Phone menu to see what differences exist between stock and Custom ROM settings
Added some lines from the stock VZW Build Prop to Custom ROM Build Prop
Removing HD Voice/VoLTE from my Verizon account
Avoided installing any apps after flashing a Custom ROM to see if the problem remained
Nothing worked! Still get Delayed Texts trying everything I could think of, except when on the stock VZW ROM. Custom ROMs may boot up showing my carrier as Verizon Wireless, but then after some random amount of time will show the Carrier as either "Unknown" (7.1.2) or "Roaming Indicator Off" (8.1). It is usually at that time when the Delayed Texts issue arises once the phone loses its lock on Verizon.
This makes me think it is a Verizon Band issue where for some reason not enough Bands are available for my phone to use on these Non-Verizon Custom ROMs. Or it could have something to do with VoLTE being active on my account at one point (I turned it off on My Verizon to try to combat this problem). Or maybe something to do with how we all unlocked the bootloader in the same way.
But what I don't understand is why I am the only person with this issue since I am pretty sure there are a lot of people on Verizon with CID 15 on Custom ROMs who don't seem to be mentioning this problem!
Any thoughts on how to fix it? Could it be a matter of augmenting the Bands my phone has access to on the Custom ROMs?
Thank you very much!
Drew
Worry not, I have the same problem on an international unlocked G900F.
The problem is inexistent on latest stock firmware, but it is present on the Oreo custom roms i've tried so far, such as lineageOS, CrDroid, Resurrection Remix.
The Only Workaround i've found so far is to enter the info menu on lineage os, dialing *#*#4636#*#* and turning off radio and On, on the Device Information menu, also updating SMSC proved to work on a few ocasions.
Needless to say, I've tried EVERYTHING this forum suggest, such as full wipe from stock recovery and running latest stock for a few days, or even flashing the latest baseband alone, but it doesn't work. I've read some interesting post about this issue on a Xiaomi Oreo device, and i'ts supposed to be an issue of Oreo roms and the way it measures the signal bars, but no fix so far.
Anyway if anyone finds a way to fix this annoying issue on the next Lineage16 I'd be grateful
Having similar issues with G900V on verizon. I've tried many ROMs old and new, latest LOS16 / RR. also I've tried other network fixes as in original post, and different hardware. I have a few of these, all EMMC15 unlocked bootloaders
Are there any developments here?
Weird thing is, SMS/MMS/calling 'works' two blocks away but I always have the 'roaming indicator off' no matter where I am, and there is a delay in sms IF it work at all. Also, this just started last month. (?) I've been using LOS 16 without network issues for a few months prior. It's is possible Verizon has changed something in the service in my area? I went to verizon to verify compatibility and try a new sim, they were mostly useless but otherwise confirmed that the g900v was on the 2020 list of compatible phones. been trying older builds (including starting fresh on the one that was working last month) but nothing but using stock QL1 magisk rooted ROM works - and that one works very well, reliable, and fast. everywhere. grrr, I'm not ready to retire my fleet of s900v, and I would rather retire them than go back to MM if this can't be fixed.
