Hello,
I have a s4 Canadian variant (rogers) with the latest modem flashed G1 I believe.
Lately I've notice signal drops on both ROMs. With omega I get them randomly and it sometimes stays lost for a while. With foxhound its not as aggressive it simply drops for a second after I hang up from a call. I've tried different kernels as well.
Any info is appreciated

It's going to be modem related rather than Kernel.
Flash the latest modem for your carrier

Currently have the latest modem. Also it seems that with cyanogenmod I didn't have the signal drops:-S at least I didn't see them but then again the Roms signal display is weird for kit kat
Modem: i337MVLUAMG1
Bump
ok so a new modem was released, flashed it several times and it's finally fixed!

Wondering help on this..I had flashed the 12B Modem while on the latest Verizon Unofficial CM11 Rom, But i experience lots of data drop. I flashed 12A but experience the same..So I jump back to 11A Modem, still having data drop constantly where I cant make calls or anything. Any suggestions? Hoping this can straighten out without me having to revert to stock rom, Plus I'm with T-Mobile on this Verizon G2.
Never had this issue til I flash modem to begin with. Only did so too see if my T-Mobile would get better coverage while on a Verizon G2..
Any suggestion or help would be gladly appreciated.
u dont have nandroid of previous CM11 prior to flash new modem?
I have had horrible luck with data on all AOSP roms running any modem. My phone usually has 1 or two bars of 3g but upon a restart or manually forcing LTE only I get great LTE coverage and speeds for a few minutes until it drops back down to 3g. Here's an album with screen shots showing my average 3g signal and when i force LTE only. imgur / a / 6fZK2 (Add .com & Remove spaces, cant post links yet)
Anyone else have this problem? Currently running the latest 12/26 CM11 nightly and the latest 12B modem. I figured the problem was not having updated modems for 4.4 as I had similar problems on my Gnex

Went to latest Stock, Data is back to normal again for me. So I know do believe it was rom related like you mention
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:
ROM - [ROM] KOT49H【4.4.2】 GOOGLE EDITION 4.4.2 by Danvdh, Kryten2k35 & Ktoonsez
Baseband - i9507XXUAMH2

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 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
Baseband Version: i9505DVUBMGG1
Network Provider: GiffGaff (o2 Company)
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

Hello all,
I am relatively new to custom roms and flashing my phone, I'm trying to learn as i go but I've found myself stumped.
I've recently flashed goldeneye rom, and ive been having issues with my signal strength, if my phone is even in my pocket i with have no signal
I previously ran cyanogenmod 11 and had no issues
I am on the MTS network in Manitoba, Canada
my baseband version is
I337MVLUAMG1
I'm getting confused when i try to look into all the different modem version
anyone have any suggestion on which one to try?
did you follow Canadian install instructions in OP. IE--Kernel Fix
Hello, I´m having the same problem with the signal.
I can´t find the fix you mention, would you be kind enough to point to it.
The rom is very well done, the only problem for me at least is the signal when the phone is with the screen turn off and i lose all signal.
I've been experiencing the same trouble with goldeneye and echoe illusion rom. As soon as I stop using the phone line or internet, the connection usually goes away after 15sec to 2-3 minutes. I have to ask the phone to look for signal again and choose the service provider to get back service, which usually takes 30sec. When I click on my service provider I get back to 3-4 bar signal strength instantly.
I can't find that link. You will have to research it.
You guys should really start your own threads in Q&A. Hijacking one makes it hard for others to follow with 3 different posts on maybe 3 different solutions. It may or may not be the same answer for all of you. One may just be not a clean flash. One may not be flashing correct modem etc. I am not on i337m.
When you start your thread give all your info like phone info, how you flashed, any details on what you did to fix, build number etc etc. More the better.
Good Luck--:good:
if you're on kitkat based rom but still have jelly bean modem you will have signal drops. when I updated to kk I first flashed the modem alone (NC1 in my case) while still on jelly bean and then I updated to kk based rom.
Sent from my GT-I9505 using XDA Premium HD app
I recently upgraded to GoldenEye 53.
Ever since installing this ROM I seem to be having issues with LTE reception. It's not as consistent as it used to be. Sometimes I won't be able to get data, and then if I turn mobile data off and on again using the control panel, it will start working again.
My baseband version is i337ucug0c3 in case that matters.
Any ideas?
I have the exact same issue...... thinknig of updating Baseband to NJ4 as that seems to be one that alot of people are using!
