HI,
I am using ls980 on android 4.4.2 unlocked
1. I want to put my phone on GSM only mode , i tried everything nothing seems working neither any app from play store is working , I am rooted.
2. Can I downgrade or upgrade my phone and still have phone unlocked ( i bought it unlocked and dont have code to unlock it again )
whats up man, try this out, go to settings
tethering & networks
Mobile Networks
Third one down should be, Network mode
open network mode, set GSM/UMTS
I wanted to note, I edited my build.prop, ro.telephony.default_network = 3,
I have advanced signal status installed from the playstore, set to GSM auto (PRL)
My Preferred network mode: GSM/WCDMA according to the phone. Best of luck!!
your phone is not supported

For gsm only number is 3 but in network it will show wcdma/gsm but you must be on gsm only , check network under about yo see which network you are getting
Tell me what steps you did if you got success without bricking your device

My experience with CM7 has always been negative regarding cellular service. There's always some problem. If you want to fix your problem, and you don't care about losing CM7, try flashing the latest stock firmware you are comfortable with using onto the phone, with the latest baseband that is going to work in your country.

What is your firmware/baseband?
Your problem is probably in the baseband. Or your service provider isn't in that area with that coverage? Try flashing a different band or ftf.
are stock recovery and boot files same for all regional versions of ruu. Please ans me. I am having problem afterrevert back to ruu. 3G net work stop working and I can't use 3g internet. Please help, if anyone knows about it.

Are you able to use 2G atleast? Did you check the APN settings for your carrier?

Yes, I can use 2G. I checked apn settings. When I select WCDMA only, network just goes off. but when GSM or WCDMA Preffered is selected, then only 2G starts.
Hey all. I'm currently running a D855V (Australian model) rooted on stock Android 4.4.2.
So I recently upgraded to Lollipop but couldn't use it fully due to issues with some other software of mine. So I used the KDZ method to flash back to 10E. Since then I've lost all 4G/LTE on my phone.
I've tried changing the networking mode inside the mobile network settings from GSM/WCDMA to GSM/WCDMA/LTE but once selected my entire mobile network will drop. From there it will regain network connectivity for about 10 seconds (minus any data connection) and then drop off again, showing no network. It will continue to do this until I change the network type back to GSM/WCDMA or reboot (which defaults the connectivity method back to GSM/WCDMA anyway). I tried flashing the 10C firmware too (for Australia) but this will do the exact same thing.
I've also tried changing the LTE RAT settings inside the hidden menu to GSM/WCDMA/LTE and it still won't connect. It will drop the network like the previous method but will then reconnect only with a HSDPA connection rather than 4G/LTE.
I've checked the SIM card in another phone and it works fine with 4G/LTE. I've also checked my IMEI and it shows that I do have one so I can rule that out. Right now I"m at a loss. I'm thinking I need to flash a new radio or baseband but I can't find any info about that from any of the other threads I've read.
Any info at this stage would be great as it sucks having the 2nd best 4G speeds in the world and not being able to use them.
Cheers all.
EDIT: Resolved it by flashing KK modem/baseband. Thanks to JDr0iD for the suggestion. Turns out the KK and LP basebands are done differently. Figures considering the massive overhaul they've done with it. Anyway the modem can be found here - https://mega.co.nz/#!61QBVS5B!pa2xdGyeWAJKyAazkz9O8qc5b9hJOpxX5kaU_aFdjq4

Hey mate. Do you think modem is still linked to lollipop? Try another modem or restore EFS to see if makes a difference
Sent from my LG-D855 using XDA Free mobile app
think it might be an lteconfig issue?
From my research on the subject, it seems that Google has seen fit to remove access to the hidden menu that allowed us to switch bands? I've been looking for a way to change it or access the menu for a month now, and come up with nothing. I live in India, and my provider is Airtel, which uses the 1800 and 2300 (maybe 2100 as well?) bands, both of which my D855 support. My mother's Xperia Z gets LTE just fine. I've switched the network to 'LTE only' in the Testing menu, but that just cuts off my connection to the network. It's usually set on the default, which is LTE/GSM auto (PRL), and which HSPAP works on perfectly fine. I don't know if it works on the stock ROM, because I switched ROMs before I got the connection. Currently running the crDroid 05.02.16 build. It's not worth switching back to stock just for LTE, but it is annoying to not get it when I should be able to.
So basically, I'm looking for answers to 2 questions:
1. How do I switch bands?
2. Will switching back to stock, switching bands, and then going back to crDroid work? Would the band change persist across flashes? I doubt it, but if that were possible, I'd be willing to do that.

Did you update the apn for your carrier when you went to a custom rom? if not do it first and check if it solve the problem.
if you did uptade the apn but it still not working try this: go in phone dialer and type *#*#4636#*#* ---> phone information scroll down you are going to see "Set preferred network type: (select the one you want).

Already set APN, and preferred network type is on LTE/GSM (PRL). My mother's Xperia Z has the same settings, and gets LTE just fine. Switching it to 'LTE only' makes me lose signal altogether.

the compatible band for D855 are LTE 700 / 800 / 900 / 1800 / 2100 / 2300 / 2600 airtel in indian uses 1800/2300 bands. Thus your phone is compatible. Thus I assume the problem come from your phone and most probably you might want to flash the Modem ....
What i suggest you is to backup everything and try this rom for d855 http://forum.xda-developers.com/lg-g3/development/stock-d855-30b-images-kdz-flashables-t3282012
the modem is already in it. If it work your modem will already be flashed for marshmallow as a result switching back to your ROM will not affect the Lte compatibility.

Thanks! I'll try that when I have some time, but for now, I can't have my phone out of commission. I do have a TWRP of stock Lollipop; would restoring that be enough? That would be much faster, I could get that done in less than an hour. Or is KDZ flashing MM the only option?
Sent from my LG-D855 using Tapatalk
Restored stock LP from TWRP backup, and tried changing the band. Tried bands 3, 5, and 40, but choosing any of them only results in the phone searching for a network and not finding any. When I set the RAT to GSM/WCDMA/LTE auto, it reconnects and I get HSPA+. Switched back to crDroid soon after.
I'll try flashing the modem from the KDZ soon, and then the whole thing if that doesn't work.
