[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] xcover 2 (GT-S7710L) not getting high internet

Hi all!
1. I bought my phone (xcover 2 GT-S7710L) in the states, and when I brought it back with me to Israel, the internet doesn’t work properly. It's very slow, and shows only "G", not 3G, H or H+ like it should. Is there anything that can be done? A new modem?
2. I tried to update it do KK (from JB), and it wouldn't recognize the sim at all. Perhaps it's because I got a rom for S7710 and not S7710L (?) - do you know about a rom that supports the device? I've tried both Vanir and CM11, with no success.
Thanks! Itai

zilmsys have
Did you ever get this figured out? I'm having a similar problem with my GT-S7710L (i'm in the US) after having flashed Rom and recovery for the GT-S7710. Except I have not mobile data at all. I can still text, call, and I have wifi.

nope

The KK rom (for GT-S7710) i've flashed made the phone pretty useless - sim not working at all.. I manged to flash the JB stock rom, and it is back as it used to be - low speed internet, and a working sim card.

Still no data?
This solution worked for a Danish guy with Telenor carrier.
"There are plenty of fields in an APN entry they my provider/carrier did not address, MVNO type for example, and that one turned out to be the problem It was set to 'SPN' by default, but it should be 'None'. I found that out be reflashing a CM11 M12 and checking the APN settings.
This particular misconfiguration is of course specific to my provider/carrier, but it is probably a general problem for people with mobile data problems."

Still no data. Wow cyanamod is so much better then touchwizz crap. But how can I solve this problem. Do I need to change on the APN?

I just got 2 updates from Cyanogenmod and my data is working. Finally

[Q] No 4G/LTE in my LG G2 D802.

Hey guys,
As you can read in the tittle, my problem is that I don't have 4G/LTE I get 3G+/3G or HSPA+/HSPA.
Right I'm running Lollipop with the custom ROM, BlissPop with B14ckB1rd Kernel. I tried other ROMs (CM, RR, Paranoid) but I don't get 4G in neither of them.
I lost my 4G a quite ago, don't remember exactly how but I can imagine it was when I tried those early Lollipop builds, after that I went back to KitKat and the 4G was gone, even I tried going to full stock but neither that work.
I'm sure is a phone problem because I been with 2 different carriers and couldn't get 4G. The SIM card is brand new and today I spent around 2 hours talking with the Tech Support of my carrier checking everything is all right.
I also tried to change the Baseband/Modem/Radio (Right now I have Cloudyfa KK for the D802).
This might be also helpful for guess what could be the problem, when I dial *#*#4636#*#* go this phone information, down to prefer network type and select LTE only I lose service, by the way, in that configuration I have selected LTE/GSM/CDMA auto (PRL) and USA radio band.
I'm open for all kind of suggestions, If you need more information don't doubt in asking me.: fingers-crossed:

I am having exactly the same issue. I have been going around in circles since days. Recking APN settings constantly etc. Going mad. Would be great to find a solution together!

Well is good to know I'm not the only one.
Could you share more information?, like when and how it happened, so we can figure out what is wrong.
Today I'm going to try to get some logs, and check the system folder.

It happened to me with stock lollipop v30d vodafone ITA with another carrier sim (TIM). Solved after flashing v30a open ITA kdz.

I'm gonna try it, will send feedback as soon as possible.
Sent from my LG-D802 using xda Forum

No luck, I installed the V30a Italian version as you suggested but as you can in the screenshots no 4G at all, when I try to force LTE (This time with the command 3845#*802#) is lose service like in my last ROM, so I'm almost sure is hardware and not software.
Can some confirm me that, cause when you go back to stock by a kdz or how ever their is not residual imformation, every thing is fully clean right? Or some firmware just stay for ever?
If you guys have more suggestions that could try before I send it to somewhere for get it repair.

Recent unimagined issue with data network.

From couple of days I am facing a bit unique problem that whenever I enable my data into #GSM it shows h+ and runs 3g and after a while it auto changes into E from h+ and within a minute data network gets disabled.. And again it auto enable data and same process starts: h+ to E, E to h+ and disable / enable.. Network data gets disable enable automatically...

Maybe a provider problem
Hello and thank you for using Q/A,
did you try a factory rest. It can be a provider problem.
Kind regards

How you recently update your phone's firmware?
If so, Its not really an unique problem, since I am experiencing the same.
With an OTA update to I9505XXUPOL1, my data connection was not working at all.
To fix my data connection problem, I have flashed I9505XXUHPA1, which was stable connection, but only E (gsm) connection, it has disable LTE.
Sources within this forum say that I9505VJUHOK1 (south america firmware) works properly, I have not tested it yet. If some can confirm please let me or us know.
I download my firmware from the sammobile website

Hehe... I think it occured after couple of master reset?

*IIhan87 I flashed 4.4.2 firmware long time ago and the problem occured now... My baseband is XXUGNH6. And it doesn't have lollipop firmware too if it had I would have tried latest firmware to solve the data network issue: (
