GoldenEye and LTE - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

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!

[Q] About CM mini RC1

i had just flash this firmware, its running smooth and the only problem is the gsm signal went up and down all the time even im using 2g network only.
i found this firmware has a lot of potential and even the app2sd is there.
can anyone tell me also which system application is safe to remove?
do you have baseband 015?
yes, baseband 015. everything seems ok for now...just the signal bar~

S4 latest Roms from foxhound and omega signal drop!

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!

Data Drops after Flash 12B Modem

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

Service Search Issue *Solved

I have recently updated my 1337m from Bell from 4.2.2 to 4.3 darthstalker and I am having a weird issue. When I turn on my phone screen I lose my reception and it searches for it again. Sometimes it will find it instantly other times not at all. If I go to search for networks and then hit back while it is searching it will find my provider, bell. If I lock my phone while I have reception my phone will continue to get reception and I can receive calls in text but if I lock it without reception I do not get reception.
I also tried flashing to 4.3 hyperdrive rl12 but the same thing occurs. I also have uses the kernal that came with darthstalker ROM and ktoonz most recent kernel and again I get the same issues.
Sorry I've searched for this issue and could find anything. If you need any more info please let me know.
Thanks,
ab111
*Solved. I was using the 4.2.2 baseband. When I updated the baseband it fixed the issue.

[Q] i have a question and i'm confused.. plz help me

ok here it is. i've flashed various roms but don't really know what everything is, i just followed all those insturctions but never bricked my device..
I live in China, use 3g mobile internet, my phone is korean note2(shv-e250l), use slimkat 4.4.2 nightly, bandwidth MI1, kernel thor 2.9.
i've been using these for about 1 month, and there was not any big problems, except that it feels like my signal strength or internet speed isn't as good as stock rom
but yesterday, when I hung up after calling my friend, all of sudden my phone can't read my sim card, so i reboot the device, and my mobile network doesn't work, and i reboot again, finally everything works.
after that, everytime i call someone my phone goes stupid and i have to reboot it twice.
and I started to wonder, does my bandwidth need to be updated? can I use newest stock rom's bandwidth?
newest stock rom of korean note2 is NA1, will using its bandwidth solve my problem?
if it does the magic, how do i apply bandwidth of NA1 to my phone?
HELP ME.............
