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:

Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

I'm having the same problem, but with G900H. I have stock firmware, rooted and everything's working fine until suddenly, I have no network. I restart the phone and get network again but only for a couple of minutes.

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:
imgur.com/i69HCBM
with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch
(sorry for messed up links but I can't post to outside sites yet)
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.
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
The phone is running the latest bootloader and modem? Data works on a stock ROM?

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.
