Hi,
i'm currently running the latest CM13 and have a problem with the Preferred network type. It stays on "LTE (recommended)" and i can't change it to 3G or 2G. In Phone information (*#*#4636#*#*) it stays on "GSM only" and won't change to anything.
When i go back to LG's Stock 6.0 all changes work. With previous versions of CM13 (first 5 versions i think) it works also.
Does anyone have any idea?

I have the same issue on my LG G4 h815. I cleanly flashed the latest nightly of CM13 (cm-13.0-20160102-NIGHTLY-h815.zip), after first upgrading to the stock 20A image and installed TWRP. I flashed CM13 using TWRP. Then I flashed nano gapps. H+ is the fastest cell tech here, and my phone just can't use the cell network (it seems to connect, but never shows H+ and no data bits are routed). And when I went into the menu to select 3G as the preferred network, it won't let me change it from LTE. It clicks when I choose 3G and 2G, but the selection stays on LTE. When I go into the special menu for radio options, same thing, I can't select a different network mode (it simply stays on the current selection). Wifi works just fine, but cell phone use doesn't work -- no calls, no data. I also upgraded to the next nightly, but it didn't make any difference in behavior.
@Chipstepper Can you tell me which CM13 image worked? I'm going to try cm-13.0-20151125-NIGHTLY-h815.zip ..
Same Problem here on my Moto X 2014. I tried every CM13 nightly between Christmas and early January. I was never able to change the Radiobutton in Preferred Networks and connection in phone information was always GSM only. I also tried a clean flash of the cm-13.0-20160108 nightly, still the same problem.
Now I switched back to my CM12.1 backup where it's working.
Can somebody name a nightly where it's confirmed working?

I have CM 11 latest nightly installed. I noticed in mobile networks->preferred network type is 2G and 3G, no 4G. what happened? Do all CM rom have same problem? I followed http://forum.xda-developers.com/showthread.php?t=2707029. I tried to select one from drop down menu, but it always goes back to 'WCDMA prefered'.

Hi all.
i flashed last nightly version of CM 13 to my d855.

I had the same as your Nº 1 Problem, i tried to go to *#*#4636#*#* and force the phone to change to 3g but it didn't work either.
So i went back to my previous rom (XenonHD 5.1.1) y enter the menu on *#*#4636#*#* and select wcdma prefered (and i dis change).
I flash again CM 13, and the phone got 3g, but i can`t change the network mode, so i only got 3g or 2g.
i think that the rom doesn`t actually have the right permissions to change that now, hope it gets solved.
Hope you find this helpfull. And sorry if i misspelled some word, english is not my home language.
Thanks i got clearly. Not my home language too
1. As for your signal problem, depends on your carrier as CM is trying to be universally available to all carriers.
2. And as for the "invalid number" error, it is a very well known CM 13 issue according to CM moderators and developers and has been pushed to get fixed in upcoming nightly releases.

Have the same number 1 problem. Htc one m8 dual.
When i bought D855p it came with 4.4, then i updated to 5.1, all official. After this i installed Cyanogenmod 12.1 and everything were fine. But when i installed 6.0(poland) my network signal keeps droping the intire day, it changes to UMTS and HSPA. I cant use my phone as a phone. The only way to solve this is, every time that i turn off the cel or put in airplane mode, is enter in MOBILE NETWORKS > NETWORK OPERATORS > SEARCH NETWORKS and choose GSM. (but i need to do this EEEEEVERY TIME that my cel turns off/airplane mode).
6.0 is the only ROM that i can choose GSM and the signal keep ~stable~. At least i can use my phone as a phone !
I did a backup of my IMEI before installing cm12 as well.
Things that i already tried :
-Flash ALL modem (ALL) , including 21C.
-intall cm13 and after cm12. Using TWRP 2.8 and 3.0.
-stock 4.4 , 5.0 , 5.1 and again 6.0. Using LGFlashTools
-MANY factory resets and wipes !
anybody can help me ? :good:

Try this. However in your case download the Polad specific .kdz files

Doesn't work , sadly :crying:
i also tried to put in Network mode : GSM/WCDMA ( worked ) but when i choose GSM/WCDMA/LTE auto , signal drops every time. It is a solution to do this, but i cant use my LTE, and it sucks ...
Disable VOLTE n go to ur models service menu (check google) for me it was
*#546368#*851# (my model = d851)
*#546368#*XXX# (ur model=D8XX) verizon sprint numbers are differently
go to field test >network mode>set GSM permanently (try different gsm 850,990,etc)
Back > RAT selection > select GSM
U cant have network problems now cuz ur permanently set to gsm dont use 3g or 4g use wifi
hit like it helps

I'm sad to hear that. Try also flashing modem 21C. There are also other guides for restoring your signal around the forum, different things seem to work for different people.
Hey guys,
i recently clean Updated from Fulmics 2.7 to latest 7.5. Everything worked fine until i suffered from Network completely droping while Wifi is active.
I tried different scenarios. The Bug is now reproducible.
1. LTE/3G/2G Auto Mode + Wifi >> Signal loss
2. LTE/3G/2G Auto Mode without Wifi active >> Signal stays active
3. 3G/2G Auto Mode + Wifi >> Signal stays active
4. LTE/3G Auto Mode + Wifi >> Signal loss
I tried almost every Modem available for the G3 in development section(21A,21C, Those hybrid types etc.). I tried different Roms now (Cloudy, Fulmics 7.0, ZOEs).
I made a clean install of the original Firmware (V30B via LGFlashTool). Reinstalled my Backup from Fulmics 2.7
Then i tried setting different APN Settings and tried messing around with LTE Bands in the hidden Menu. But nothing worked so far.
The Issue stays over all Roms and Firmwares and Modems and Fixes i tried
I really don't know what i can do now to fix this. Maybe s.o. got a Clue or Hint what else i can try.
The LTE function is essential for me because my Provider (O2 Germany) only builds LTE Networks and 3G got less coverage here.
The only thing i can imagine is that the SIM Card or the SIM Card Holder somehow got damaged??? The Card worked proper with Fulmics 2.7 for about 2 years now. Until the Update.
Thanks in advance

No one suffers from this?
Having Ressurrection Remix installed now and it works fine. So it has something to do with the Stock LG Rom?

I was having this problem on Fulmics rom but it was not total loss of signals. It keeps on connecting and disconnecting after few seconds. Stock works fine though.
I have the same problem. Using T-mobile lg g3 d855.
Trying to resolve still...
