[Q] - i9507: No service on KitKat - Can receive calls, can't dial (no service)

Hi Guys,
I'm from Australia and recently bought an Optus Galaxy S4 4G. Strangely, the model number is i9507. I double-checked this online and usually weird model numbers are just carrier-spin-offs. So I went ahead to root and flash just like you would with an International i9505.
So far no problems - 4.3.x PA rom works absolutely fine.
BUT:
I've tried some Kit Kat roms recently and they all flash fine but give me 'mobile network not available'. Strangely though, I can receive calls/text and talk on the phone, but when I try to dial or send text messages, I can't do it. My reception bar is completely empty as well.
WiFi is totally fine, just no data and mobile network
I've tried messing with the 'network operators' setting and if i select my carrier (I have a Vodafone sim) I'll get network reception until I turn off the screen and then my mobile network becomes unavailable again
Not sure what the problem is; modem? APN? or roms not suitable for my phone?
Current info:

I've been flashing for a while now but it's usually just basic stuff so you can probably tell I'm pretty amateur lol.
Any help is greatly appreciated!
Thanks =)

Hi Rich
As your baseband is quite out of sync with the firmware you are trying to run (MH2 is from 4.2.2 ,,, right?) I would suggest you change your baseband (modem) flashing an equivalent to the ROM firmware from here.
I've got yesterday the exactly same behaviour when finally and reluctantly I've added a data plan. I was running a successful low-baseband + high-firmware because was setted to "GSM Only" (try it ... will work flawless). When I've switched to LTE got what you've described in the face too . I've promptly updated my baseband and now all is fine :angel:
EDIT: please do nothing of the above described BEFORE taking a EFS backup with every tool you can find and preserving them in several highly fortified locations and 2 or 3 K7 Tapes too . Have an ODIN flashable copy of your MH2 baseband is advisable too.
Hope I've helped and please share your experience.
Nice regards.

Hey thanks for the reply! Helps heaps =)
While I still had those roms installed I did try flash a few modems within Odin, all failed though =S
Which one should I be flashing?
I believe I tried XXUFNA1 but the flash just doesn't go through
Does it make a difference which rom I flash the new modem from? I.e. flash when the new modem now or flash the new modem on the kitkat rom?
I'm currently using Pacman 4.3.1 since it's perfectly fine. Just can't wait to get on a KitKat rom though! haha

Hi Rich
Sorry, may be my fault, but quite didn't got your
You may proceed having the below as a rule of thumb:
Your baseband (modem) version should always match your ROM (firmware) version.
Failure to flash something is never good signal. As you have an i9507 (I own the 5) is very advisable to flash a modem built for your S4 flavour.
The above rule should apply to it too so, if the only modem available for the i9507 is the MH2 your firmware have to match or these issues reported will return.
Did you tested the "GSM Only" option to corroborate (or not) my hyphothesis? With this config, you should perceive no signal drops when waked. I know it isn't a viable operational mode but ... just for fun
Nice regards and keep sharing :laugh:

[Q] LG G2 D802T 3G after root?

Hi
There is a lot of information on various thread about this but nothing really makes it clear to me what I need to do to fix this issue. I'm posting as I'm sure I can't be the only Australian user with this issue.
I rooted my phone and am using a custom ROM, now I am unable to get 3G data. When my phone switches to 3G no data is sent or received.
My understanding is that this is a modem driver issue. But I'm unable to find any instruction on exactly how to fix this.
Android Version: 4.4.2
Kernel Version: KOT49I
Software Version: CloudyG3 2.0
Any help would be appreciated!

Its not a modem issue I thinks. Its band settings issue..
U have a custom ROM. What's ur default telephony network? In build.prop
*#*#4636#*#* what's the default settings? Its equal to default network. Also available in mobile networks as Set network mode.
If you change from the info command. Does settings sticks after reboot? If not then you have to edit build.prop

[Q] How to use EDGE network mode Sprint S4 ??

the phone uses HSPA+ which well if you are a pre-paid customer in a 3rd world country find it hard to manage. it chews up all my airtime within a minute or two, so i went custom. installed Omni ROM 4.4.4 and found that GSM Only radio button, which is missing in the official NG2 4.4.2 ROM. then i did sth wrong and had to flash the official ROM again but look, it retained the settings from the omni rom. that's when i discovered it had the icon for E. so am guessing there's a work around without having me to flash a custom rom, or is there not?? Please Help!!

Solved!!

Mobile Data Won't Work.. Have Tried Everything

Hi, so I have a Canadian Samsung Galaxy S4 SGH-I337M.
I recently flashed Synergy's Cyanogenmod 13 that would allow me to run marshmallow as they have discontinued for my model on the official Cyanogenmod site. After I flashed Gapps Pico and everything was working fine until I tried to use mobile data...
I tried everything I could find i.e Airplane mode, DNS Changer, VPN and most notably changing APN's. As for when I changed APN's I am with mobilicity so I just changed the APN to wap.davewireless.com as instructed on their site but didn't work. I thought it was because "Synergy's CM13" might be "sketchy" so I also flashed CM11 made for my model off cyanogen's official site as well as Resurrection Remix still didn't fix the problem. Is there anything I can do to access my mobile data.
BTW: I can receive calls, texts, voicemails literally everything but my data. I can also receive texts from mobilicty about billing if that means anything.
Plz Help and Thanks
