H815 CM 13 - Mobile network disappears

Hi. Recently I installed Cyanogenmod 13 on my LG G4 H815 (international, without any broadband) and I like it for some reasons, but I have one issue.
Sometimes my network connection (I prefer using 3G, but the same is with LTE) disappears and I have only GSM without internet connection. There was no such problem with stock ROM.
I flashed cm-13.0-20160721-NIGHTLY-h815.zip. I searched a little and found similar problem with CM13, but on OnePlus One forum.cyanogenmod.org/topic/118316-cm13-mobile-data-connectivity-issues/
Not much I found.
I attach my screen when problem appears: i.imgur.com/zntwdZu.png
Thanks for your help.

I checked some stuff with ADB.
1. netmgr is working
Code:
h815 / # ps -A | grep netm
radio 10063 1 23900 3472 v_datagram 7faeaf3fe4 S /system/bin/netmgrd
2. I can switch mobile data connectivity with commands
Code:
svc data disable
svc data enable
3. There is no any messages in dmesg while turning data on/off.
4. Reboot seem to fix this for some time.

This is known problem, see CM thread...
Switching back and forth flight modus should help

I cannot find thread you speak of. Would you share link with me?
Airplane mode is good idea. Also turning off and on rado in *#*#4636#*#* menu makes it work immediately.

Data Sim switch not working in terminal or shell

Hi,
I'm using a sim in slot 2 just for data when I'm abroad (chatsim). I tried making a tasker profile which would switch data to sim2 when sim1 is roaming.
I've tried using a root shell command "settings put global multi_sim_data_call 2" and it does switch the data to sim 2 in the settings but actually nothing happens further.
The data is still on sim 1.
Does anyone know how to activate it? Maybe a command to restart the RIL?
Thanks for any help

Have the same problem ?

Any news on that?

Hi, this might be late but try changing SElinux from forced to permissive. It should solve the problem

No signal in 2G / How to put phone into Qualcomm Diagnostic mode?

I have a problem with one of my Mi6 phones: it completely losing a signal while working in 2G network.
The problem looks very similar to USA band problem in Mi5. May be reseller flashed or enabled somethin like this mode on this phone.
The problem is I can't fix it at all. I tried to erase and flash different modems, tried different ROMS both MIUI and AOSP based - no effect, still no network in 2G.
I found a method to fix bands using Qualcomm Drivers and QPST tools, but I faced a problem that Mi6 declines to enter diagnostic mode either using *#*#717717#*#*, tried adb shell commands and, finally, tried fastboot edl reboot option. All of them doesn't work at all. ADB Shell - just nothong happens, Fastboot - usual reboot of the phone, *#*#717717#*#* - "Open diag failed!".
Does anyone face same problem? May be there're some more soltions or I doin anything wrong?

i experience similar problem. although phone shows signal in 2G, call is either not possible or very poor quality. only answer i got that it's a service provider issue, but the same SIM cards work in Oneplus 3T, HTC One M7 and different kinds of iPhone.
I suppose it's a modem failure, but i haven't found a way to diagnose it more deeply without voiding the warranty.
Maybe you have any success what is the problem exactly? and, maybe, how to solve it

Moto z2 play india jio 4g roaming problem

Hello there, i would like to ask you guys, currently my jio sim is in roaming (since I am currently living in another state) and a strange thing is happening, i can use the LTE data but I'm unable to receive calls or make a call using SIM 1, even the problem still persists after the oreo update, i thought there might be a problem with the sim card but it's perfectly running fine on my another android device, I've already formatted my phone 2wice after the android orero update so, can anyone please check or confirm is they're having the same problem with the MOTO Z2 PLAY INDIAN unit while ROAMING on JIO 4G??
PLEASE HELP

Go to Settings > More > Mobile Network settings > Access Point Names
Tap on the '+' sign on the upper right corner.
Than create new APN profile with the following parameters:
Name: Jio
APN: jionet
APN Protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Bearer: LTE
Leave all the other options as they are.
Then save this APN profile from three dots on the upper right corner.
Choose this profile now and restart your phone.
I hope it works for you.

You need to flash stock ..then apply the fix given for Indian users ...then backup esf and flash crdroid or resurrection or lineage and restore efs

This problem was solved by installing Gravity Box and enabling - enable national data roaming option

hii, i want your urgent help. I have MotoZ2 Play (XT1710-10) which has some issues i didnt look upon while buying the device as it was used for home. I want to flash Stock Firmware but dont know which one for Indian Variant.This can be found by using the CID (Country ID) value. ALL you have to do is run a simple fastboot command to get the CID:
This would not kill your phone or root/harm or to stole your personel info
I cant ask it in general bcoz CID changes with Model Variant and i have Indian (XT1710-10)
Poweroff the device and enter into fastboot mode (Power+Vol(-)) button
Code:
fastboot getvar all
this will give detail about your device , you can find
Code:
(bootloader) cid: 0xXXXX
Q.Why i cant get the same..?
Bcoz Mine CID is 0x0000 which is creating some issues
If i can know my Country ID (CID) it would be a great help in flashing my phone with correct firmware
Thanks!!
