Okey i got I9505 with the new bootloader and i cant seem to get LTE working , as it's doesn't even connect and drops all connection ever couple of minuts or so. I've tried flashing all kinds of modem but it doesnt seems to help so does anyone know how to fix this problem ?
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.
Hello! I have a big problem that i cant find a solution. I opened engineered menu (*#*#4636*#*#) and from phone information i changed by mistake cellular band to usa(gsm-850/PCS-1900...) Then sim1+2 now has only LTE band working. Not 2G/ 3G. I make hard reset but not solved the problem. Please help me!
You'll have to flash a baseband (modem) file. That's what works for Moto phones. Might work here. Or simply flash stock rom.. wiping all.
Posting here since I don't have privileges to post in the development forum. Has anyone tested squid2's CyanogenMod ROM with T-mobile US?
I flashed the ROM after factory wipe and everything works except call sound. However, if I set the network to 2G or 3G the problem goes away. Has anyone been able to get phone calls to work while on LTE? My model is an XT1607.
Similar issue was reported but someone said doing a clean install worked for them. I experienced the same issue as you do but don't have the time to do another install to really see if it solved the issue or not.
Yeah I saw that post as well, unfortunately it did not work for me. I tried wiping and re flashing a number of times. I wonder if this has something to do with VoLTE support like in this thread: forum.cyanogenmod.org/topic/125114-cant-makereceive-voice-calls-on-the-t-mobile-lte-network-after-cm-13 (copy/paste since I can't post links yet)
Same problem here on a clean install of 11/9 cm13. I'm going back to stock for now. Hopefully if we get a working cm14.1 VoLTE will be working.
Hey Folks, as we all know how stock ROM sucks, I remained on custom ROM to max extend. But sadly I have to revert to stock due to network fluctuation issues. I use Jio as my primary and Airtel in SLOT 2. Fluctuation is widely seen in slot 1 which is reported by many others as well in respective ROM thread.
I have tried methods flashing custom modem image and network signal guru. But none seems to fix the case.
Anyone aware of other methods to fix the network fluctuation issues seen in custom ROMs? May be using any custom kernel?
Please help me to remain in custom ROM!
Cheers,
Hari.
Same here all cust rom has this network fluctuation issue and it is to do with the code. It seems if any one can fix this. It will be great..

The same, please helppppppppppppppppp!!!!
Noticed the same on Vodafone AU, no matter what network mode I set it to. Even on 3G only I get drop outs and fluctuations.
I'm hoping it's just some extra modem related package or service missing from the vendor blobs, but I've not had time to look into it yet (with my limited skills in this area).
For me also lot of fluctuations. Sometimes totally black signal bar. Hope somebody can fix it. I fixt it for now with automate and set network to 2g when on wifi and after lock screen when I am on mobile network.
Modem zip in forum don't solve it for me and also lock some bands with signal guru didn't do the trick.
Hope somebody can solve it a lot of people are suffering this problem.

Has anyone tried using custom kernel? Just curious on if any custom kernel fix this.
Same issue I have been facing, I had re-partitioned my device for Treble using CosmicDan's guide so that I can try all the best custom roms out there and get all updates as they are released but when I faced this issue, I had no choice but to revert back to Android One rom, undoing all the process

Nope change kernel don't solve network problems it has something to do with the modem.

Probably resetting modem settings, assuming you've made any.
China only uses maybe 5 bands, and most of the population doesn't often travel far from home; so roaming and tower switching isn't an issue. That, and a power management issue I think are responsible for our network issues.
My money is on these devices working perfectly in the motherland.
Faced the same , almost on every custom ROM .Jio 's volte doesn't work most of the time. Switched to January stable stock twrp with magisk . Now everything is stable , no volte issues at all .
Now my question is , the issue is with ROM or modem file ? As you guys are saying that it is a modem issue ..as now I am on January stable modem , I will try to flash a latest build of any custom ROM and will report .

There's a TWRP flashable May modem patch somewhere in the MiA1 forum. I've flashed it and the results aren't perfect, but circumstances have improved.
I have tried all March, April and May modems and all have problems with custom ROMs and network fluctuations for me. (IND Airtel operator) and even 3G is fluctuating with state owned BSNL. January is the only one I haven't tried which I will after getting a reply from sikoo1996.
I have very limited knowledge of these matters and so far all my attempts with dialer code menu or settings or Network Guru have all failed. Guess I will ditch this phone and stick to my S5.

Rit now I am on jan stock build , means on Jan modem .I will flash a custom ROM now ..later today and will report back about the issue .
Cheers?
I dunno if it actually works for everyone but,
Swapping the SIM card slot worked for me.
Using RR latest. I also flashed stock modem.img but that didn't fix the problem then. It's fixed now by swapping SIM slot.
Hey guys. Try flashing the latest modem and then, go oh ahead to *#*#4636#*#* and select network mode to TD-SCDMA/CDMA/UMTS . ?

As @methuselah pointed out, there is a more appropriate place for this conversion.
