How to installAOSP/CM ROM with Sprint LTE support - Sprint LG G2

For the LS980, how should we install CM13 so that we can maintain LTE connectivity?
Let's say we do full stock and upgrade to ZVI via OTA, I have tried many ROMs and bootstack, there are no data service at all.
Thanks

Can't connect to network after restoring LG G2 LS980 to stock

Hello,
I followed this guide to restore my sprint LG G2 to stock Kitkat 4.4.2. Everything went fine, the phone is working, the only problem I have is that I can't connect to any network. The phone is not recognizing any of the local network providers. I bought this phone on ebay and it came with a custom rooted rom installed on it, so I decided to "clean up the mess" and restored stock kitkat. As I mentioned before everything went fine, but the network is not working (it was working with the android version before i restored stock 4.4.2). Maybe its because I'm not living in the USA (I'm from Bosnia/Europe). Should I flash a different radio on it? The phone is updating atm with OTA and I'm pretty sure that the updates wont help. Did anyone else had these issues? Any help would be highly appreciated.
Update: My phone just got upgraded to Lollipop, but the network issue is still present
Update 2: I just reinstalled "cm-12.1-20151031-NIGHTLY-ls980" Lollipop 5.1.1. and it had no problems to find all the networks in my area, so this clearly has to do with stock LG android 4.4.2.
When you say you can't connect to network, are you referring to your mobile carrier network, or like WiFi?
If it's your mobile carrier that you can't connect to, you might need to switch your radio. Take a look at this guide and the section about using radio switcher: http://forum.xda-developers.com/sprint-g2/help/how-sprint-lg-g2-ls980-to-t-mobile-t3230685

Hey there. Sorry for the late response. I kinda gave up on making the stock LG ROM work, which is why I kept on using CM12.1 . What I was referring to was my mobile carrier. The phone has no problems connecting to any WiFi signal.
I didn't try to flash any radios at all after restoring the LG G2 stock ROM. Maybe I should have tried one of the radios from this CM12.1 for LG G2 tutorial. Here is a direct LINK to the full list of LG G2 radios, where I downloaded the radio for my phone. I'm not sure if the other LS980 Radios would work on my device. There are 4 different radios available for the LG G2 LS980.
Do you think flashing one of these radios would help solving this problem after restoring the LG stock ROM?

Working 4G LTE on VzW but no WiFi??

I have a Sprint Moto Z2F on Verizon network.
With the Sprint Firmware I’m roaming on VzW network
I can’t get any version of the VzW firmware past the set-up stage, (Set-up keeps closing)
I did get a mixed version of Sprint and VzW firmware to work and set-up but I have no WiFi.
All the System oem img (sparsechunk) files are VzW 9/1/2018 update and the rest of the firmware files are Sprint.
What firmware file controls the WiFi?
I'd like to get WiFi working again
ok this phone is crazy!!!!
I'm back on the Sprint firmware, which works fine its just roaming and that bugs me.
3 times now I did Flashall back to Sprint FW and take the July update. then I install TWRP and Root and I'm back on May 1 update. Crazy.
now I just booted the B slot and it is updated to July first...
I still want to get the Verizon firmware to work, I know others have.
I have tried a few Custom Roms, LOS and DU but can't get them to boot. I can get LOS to boot but I have no data.

Flash all with sprint. Download latest Verizon flash all and just flash system, oem, and boot. Let me know how it works. I did that with the AT&T firmware and it runs great
Forgot the image. LTE. WiFi calling. Everything at&t works
OK, I got WiFi and VzW 4G LTE NOT ROAMING !!!
I flashall ‘d the Sprint FW, then I did a little edit on the Flashall.bat and just flashed the VzW OEM, Boot and System sparsechunk files, 11 files in all. So I didn’t have to take an update I used the Sept 1 VzW updated firmware. Now all I have to do is flash TWRP and root.
thanks
update: I've been using the phone as my daily for over a week and everything runs fine.
What are the chances that LOS could be made to work? I just bought a Verizon Z2 off eBay not realizing that the bootloader could not be unlocked. I've been on AT&T but their service isn't too great around here.
If there's a chance LOS could work I'll sell this phone on eBay and get a Sprint variant.

LG-G3 D851 - 4G stopped working on Android 7/8/9.

Dear all,
I got a strange situation and I've tried several options already, but I'm lost.
My LG G3 D851 (T-Mobile) is currently running on Lineoage OS 8.1 and my 4G is not working.
Even though I selected 4G preferred. Highest what I get is H+.
I've found a modem file, but that screwed up my 4G and 3G completely.
It doesnt matter which custom rom I select it will not allow me to work with 4G.
If I go back to the original Android 6 Rom I got 4G.
Who got an idea to get this fixed?
Is your IMEI still There ? Does your Phone Show Up at qpst? You did Not Read
anything i grüess so you probably havent Backes Up your efs? Ist there No Connection at all? Flashing Roms will Not fix your problem. But you should Go to Marshmallow Stock For now.
Custom Roms only Work with 21c and lower maybe you Just flashed The Wrong Modem. Google For The XDA LG G3 Modem thread

My IMEI is still tere.
Dont know what you mean with QPST.
I've got backups and I can go back to any state, but I dont know what I should even consider check the EFS?
I'll check the Modem thread.
Maybe I can find a solution in there.

The 21C thing is incorrect. Each variant of the G3 has their own set of modems. There is no 21C for the D851.
If memory serves we had 10 series (KitKat), 20 series (Lollipop), and 30 (Marshmallow). I'm currently using 30D modem from last time I had a factory stock installed. I get 4G/LTE on all of the installed ROMs (KK, LP, MM, N, O). Even when I was on 20G they were all good, though I didn't have Oreo at the time.
@Mr-Dutch, I have a small collection of D851 modems up on Mega. Since your last stock was Marshmallow I figure the ones to try, if you elect to do so, is 30D or 30E.

LG G3 D851, Mahdi v2.9 ROM (4.4.4), microG (NoGApps), MultiROM, XDA Legacy
Yeah my Bad that was for The 855. And there IT says in The Post that IT only works Up to 21c but Not sure If thats still a Thing.
So have you tried flashing a Modem? And does IT Work now?
