I installed the Carbon ROM (Thanks Team Carbon!!) and it is working great on my Hong Kong P705. I've also been reading the posts about the V10 and V20 basebands. My phone shows baseband=unknown. Do I need to be concerned? See attached screencaps.
(1) The phone/ROM works with my carrier, I can make/receive calls and 3G data works fine.
(2) I noticed that the phone cannot connect to certain Wifi access points.
Thank you for your thoughts/advice!
If you have GSM signal then you have correct baseband.

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 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.
Hello all,
I want to understand in a more detail how android is working because I have a specific problem with the cellular network.
On my galaxy s4 i9505 I was running a CM11 Snapshot M9 for a while without a problem.
It's ok but I often wanted to update to the latest CM11 builds (Snapshot or Nightlys) but there seems to be a problem with my cellular network.
The thing is, my provider is "yesss!" which is a discount mobile provider in Austria. With the M9 build the correct network is found and automatically connected. On all newer variants there is no automatical connection.
When I search for cellular network providers I only find the bigger ones like "A1", "Drei", "T-Mobile", ...
I can connect manually to "A1" which is a roaming partner of "yesss!" but it won't reconnect automatically and it is detected as roaming (which is correct). So basically the modem is working but there is no cance to find a connection to "yesss!"
How does it work?
I found out that even on the newer builds, the same modem is used.
I tried: I9505_XXUDMGG_MODEM.tar and later I9505_XXUDMHI1_MODEM.tar
both work with CM11 Snapshot M9 but are not working with newer builds.
So it may seems to be no problem of the modem?!
I tried to go to the "*#*#4636#*#*" menu and checked the settings:
on both versions "LTE/GSM auto (PRL)" is configured, so also no difference.
I tried some inofficial CM12 builds and other Andorid 5.0 builds.
Allways the same... The roms are working fine but the can't connect to "yesss!". only "A1" is possible.
Does anybody know what I could do?
Please help. Right now it seems that I am stuck at an old CM11 build.
Hello everyone,
A Note 4 N9108V end up to my hands, but after using it i realised it cannot properly operate in my network.
It is a snapdragon variant, single-sim version for China Mobile, has lot of Chinese stuff totally useless if you are outside China and does not have Google apps also.
I manage to root the device, install custom CWM recovery, install a MIUI7 ROM that is quite good, install Google but still have problem with 3G coverage (and LTE ofcourse since in China LTE is different than EU)
I have 3G coverage, but if i will move to another location i will not be able to make calls, and i will also appear as unreachable if someone is calling me. Also data connection will not work. Later, it may work correctly for a while.
In GSM mode is working perfectly
I took it to a local repair center to check for hardware problem, they say that it is probably the baseband (modem) software that is designed specific for the China Mobile network, or there is a bug.
I tried all the available official ROMs and modems for this device (4.4.4, 5.0.1, 5.1.1) but nothing improved.
The only thing i manage to do is to have this amazing phone working only in GSM mode....
It is like having a Ferrari with pedals.
I am thinking if it is somehow possible to load the modem file for the EU model (N910F), and this may "unlock" the needed frequencies to operate correctly. Or even, if it possible to load the entire N910F or similar non-branded Note 4 formware to the phone, since i suppose the hardware is the same.
I tried to load this modem file and the n910F firmware with Odin but is not accepted, the procedure failed.
Any ideas, proposals etc?? (except of hammering the device, this will be my last option) :laugh:
Thanks in advance
Im having issues with the 2G signal wherein signal bar is empty but for 3g its working fine (I haven’t tried 4g/LTE) . I prefer to use 2G network for sending/receiving SMS since it has strong signal in my location (Philippines) and I don’t use cellular data since I always use home wifi.
Im thinking that it might be an issue with the modem version that im using for my phone (I337MVLUGOH1)
Im just wondering if its possible to flash modem from I9505. I read that the modem to use for Philippines is MKE.
SGH-i377M model (Bell unlocked)
Recovery (TWRP-jflteatt)
ROM - cm-13.0-20161204-NIGHTLY-jflteatt
Modem - I337MVLUGOH1
Thanks in advance
