Hi all,
First of all, I have a Samsung galaxy s4 from Canada specifically from Rogers. I have got it hardware unlocked, rooted and I am on Cyanogenmod 11.
Now to my problem, I am in the Philippines and I would frequently lose signal, if I'm lucky, it would re-aquire the signal but most of the time, my work around is to turn airplane mode on and off and it would connect back to the carrier for maybe a minute and fully lose signal again.
Any help or suggestions would really be appreciated as it is such a pain to airplane mode and off when I'm jamming to my BT speaker
Here's information about my phone:
Model: sgh-1337m
Cyanogenmod version: 11-20150309-nightly-jflte
Android version: 4.4.4
Baseband version : 1337mvluamdj
If i could help you guys, help me with my problem just let me know.
Thanks all for reading.
Signal issues are mostly connected to the modem,
Flash the right modem for your phone/carrier and see if it help

Hey, thanks for the reply!
I'm a little new to this, could you go in depth on how to do so. Or maybe direct me to a few links I could follow? I am not in Canada and this is my only phone, so I don't want a chance to brick it.
Thanks!
Edit: do I need a computer to reflash the modem because that is something I don't have at the moment.
Here is a modem list. It also has a guide on how to flash.
There was another thread that included the latest lollipop modems , but I can't find it anymore.
You will need Odin which means that you require a PC.
Go to sammobile.com and check what version you need for your carrier and country

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?

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:

I had purchased an unlocked sm-n900 because I figured it might be what would work best with my carrier ( Straight Talk) here in the US. Ive had it for a little less than a month now and have had constant connection issues. Today I saw a thread http://forum.xda-developers.com/showthread.php?t=2475714 In here it is mentioned that
Choosing right modem can make a huge difference as it affects reception, data speed, stability, battery life etc.

So I figured I should investigate flashing a new modem and maybe thatll help my situation. The thing is while looking at my phones info I found out the CSC country is Argentina. Does this matter at all? Is this leading to the problems with my phone or is this from the ROM i flashed (CriskeloRom Note III V05) Im just fed up with the constant connection problems and the constant having my phone go into emergency only mode. Where do I go from here? Do I need to flash a different modem, or an entirely different rom? I dont even know if I can flash any of those modems /: Heres some more info I have Latest firmware info
PDA: N900UBUCMK1
CSC: N900UUBCMK1

Can anyone please help
Hi,
I recently was getting frustrated with the ROM Gummy. ROM GUMMY: (http://forum.xda-developers.com/showthread.php?t=2563973) so i wanted to try something new and never thought i'd get a problem as when i flashed GUMMY it was so simple and everything worked.
However, when i flashed to the ROM S4 Google Edition: (http://forum.xda-developers.com/showthread.php?t=2544474) i noticed my signal / network won't stay connected. It may work for 2mins then disconnect - so i tried another ROM thinking it was caused by the S4 Google Edition.
I'm now currently on KOT49H【4.4.2】Google Play Edition (http://forum.xda-developers.com/showthread.php?t=2557353) and still getting no signal, only if i keep changing it to automatically find a network.
I've been reading it could do with Modems, or have i really messed something up and won't be able to fix my phone? I'm sort of new to this all so if you could explain more than tell me to do something that would be great.
Phone: Samsung S4 i9505

Any help would be great.

You have to flash a new modem for 4.4 like nb9. If you have a bootloader without knox, flash only the modem.bin file. If you have knox, flash modem and non-HLOS.bin. there's a nice modem thread in the general section.:good:http://forum.xda-developers.com/showthread.php?t=2192025

HI Guys,
Still fairly new to cyanogenmod and haven not really done much other than use the regular installer.
I have no signal on my s4 since the latest snapshot update, I can receive calls but to send texts or calls I have to turn on airplane mode then turn it off to get signal. This happens on 4g as well as 3g.
Locking the screen disables signal as far as I can tell, anyone else have this issue and is there a fix somebody could walk me through if you don't mind?
I googled around and seen that it seems to be something to do with the baseband? Will I need to reinstall cyanogenmod completely to fix this or is there something small I can tweak?

You are using a really old modem.
You never updated to android 4.4.2 officially right? That means you are still on the old bootloader. When you boot to download mode, do you see a message with knox and 0x0 or 0x1? If not, then you need specific modems (wifi fix/non-hlos) to make it work. I don't have time to look for it now. If no one else helps you, then ill search for it tonight.

The further down that post, the newer the modem. I would take on of the bottom and take the combined package.
So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Hey, I also have the SM N910K. What network are you using it on?
I have that version as well without that issue. Can you grab a picture of your About device specs?
Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,
N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.
Hi everybody..im from south korea. I have sm-n910k.
