So to use this, you will need to be bootloader unlocked, magisk perma rooted, and twrp installed, DM Verity Disabled this is a must!!(its always good to make a nandroid before making any changes on your phone). What this will do is more or less provision your Lg G8 to your Desired Carrier, it will also let you change your apns, so you have volte working and also the data indicator will change to match the carrier. WIfi calling i have not been able to get working, i personally do not use it. .
*Copy the files manually, it seems flashing them directly is causing unforeseen issues*
1.Extract to Content of zip to Sdcard
2.Make a copy/backup of your own files apns.xml,,custom_apk_list.xml,telephony.xml inside /product/op/config and cust.prop from /product
3.Copy and paste the files from my zip to:
apns.xml,,custom_apk_list.xml,telephony.xml to /product/op/config
cust.prop to /product/op
make sure permissions are 644.
4.Reboot your device it should now be provisioned to your Desired Carrier.

After every boot I will be welcomed by this message:
"Current version is not available for user can't find matched cust. Check NT-code"
Additionally there is no VoLTE switch. At least I can access my APN settings now.

Hi. I have a LM-G820UM that I got off ebay a while ago. It boots as Sprint. It's unlocked and I'm on Tmobile. VOLTE/calls only work on 3G and if there is no 3G available then I can't receive/make calls. With Tmobile requiring VOLTE effective Jan, will this fix the issue to where I don't need to buy a new phone?

Only way to enable volte on a sprint unlocked phone , while active on tmobile is to bootloader unlock it. and flash my fix.
my network is gonna require volte and it is no where to be found. i have a verizon unlocked lg g8. is it possible to unlock that one with a fix to get volte to work?

Only way to get Volte for your specific network is to unlock the bootloader, as you will need the op files from the network you want to use volte for.

I'm not sure I understand. You are no longer on Sprint? If you've transferred to another carrier, you still need to use ROMs built for the LS990 as that is still the device you have.

You can set your preferred connection in phone settings, under mobile networks. So any ROM built for LS990 should work.
I have a LS990 on ZV4, official firmware but rooted and unlocked. I am not in the U.S and I'd like to upgrade the phone to official 5.0.1 firmware on ZV8 and still be able to use this SIM. Could you please point me to the right direction on how to proceed? By the way, I'm also getting 'restricted access changed' notification and signal fluctuation using the SIM I'm currently using. Oddly, using other carrier SIMs I don't see that notification. Anyways, suggestions please?

Hello Guys,
I can't see how could be possible to download a "Porto Rico" (H820PR) software in ATT version.
Normally, Bootloader checks if region code matches before flash.
Could you please explain more about this procedure?

Hello
I'm using a T-Mobile Note-8 that has been unlocked (from T-Mobile) and currently have a Straight Talk (AT&T) service.
Reason for buying the T-Mobile version:
1. Easy unlock.
2. Easy access to hotspot.
Question:
How do I get WiFi calling enabled on this? I'm currently on the latest Oreo CRC2 build...
Searched around but NOT much information that I could find for my specific scenario.
Thanks
Max
Wow... Looks like the T-Mobile Note-8 forum is completely dead.
So there's NO one who is using this device on Straight Talk?

I don't know if your carrier supports that on the H930. My first suggestions would be to reinstall the most recent H930 KDZ for your region. See if that works for you.

Hi All,
I upgraded to the latest PIE rom "US99830b_00_0902.kdz" over top of the 20H rom, dirty flash with LGUP.
I've noticed that VoLTE (advanced calling, hd voice) is missing. I've also noticed that I lose 4g data while a call is in progress.
I also noticed VoLTE options are missing in the "hidden menu".
A consequence of no VoLTE is no data while making calls, which is frustrating.
I've seen sparse references to a "USA" version of the rom that isn't out yet.
Does anyone else on the PIE rom have VoLTE options?
Who's your carrier?
AdmiralKirk said:

Verizon. All the aforementioned features were working on the 20h rom.
I have Verizon as well. If I recall their was a work around to get the US 20h rom to work with VoLTE but it was kind of a hack. I never got it working myself (VoLTE and VoWiFi do not work out of the box on any of the US ROMS for Verizon specificly). I would suggest switching to one of the Verizon branded ROMs. You can do so and still maintain root (for debloating and personalizing). I can attest that on the 30c Pie Verizon ROM VoLTE and VoWiFi do work (you have to sign up for MyVerizon for VoWiFi it seems). Also, very likely if you are switching from one of the US based ROMs to the Verizon one, you'll probably need to follow https://forum.xda-developers.com/showpost.php?p=80347089&postcount=6 that guide by ChazzMatt or you'll end up stuck at the V30 screen.
Was the work around baked into the 20h rom, or was it an extra procedure after flashing? I upgraded to the "open", "US" 20h rom and volte worked with no extra steps.

Can you flash 996 on a 998 device?

I have unrooted stock. Still curious why this latest US998 PIE rom lacks VoLTE functionality when the 20h rom had it.
I can confirm reverting to the Verizon carrier rom VS99630c does restore VoLTE functionality (advanced calling).
I don't consider this issue resolved though since I had to move my carrier unlocked phone onto a carrier rom, which included a master reset.
Does anyone know why VoLTE function is missing in US99830c rom?
edit: US99830b, not 30c

USS98 is 30b right now.
Something about it being technically U.S. Cellular KDZ rather than Open Market firmware?
With Oreo there was no difference. Apparently with Pie there are differences.

Yeah this surprised me as well...
I downloaded the regional rom's for 30b and the md5's all matched.
Verizon is dropping CDMA at the end of 2019 and moving all calling functionality to VoLTE. My understanding is if that feature is missing, then anyone using this rom on Verizon's network will lose calling functions.
At this point, it seems US99820h is the latest version for unlocked V30's on Verizon that has this capability with stock roms.
I did confirm VS996_30c has functional VoLTE. However since I was stock I had to master reset.
Hopefully a new version of US998 comes soon with functioning VoLTE.

Verizon announced back in July/August they were extending CDMA for one more year. Too many people weren't ready?
Now it's end of 2020. I had posted about it before but here's another look.

Thanks for the update. Google's first hits were still saying end of 2019, so its good to have the right date.
In either case, I've reverted back to US998_20h for now. I'll keep an eye out for a pie rom with confirmed VoLTE.

I did cross flash from us99830b to vs99630c and it did provide me with volte, however I don't prefer Verizon's branding on the phone, so I elected to revert to an unlocked rom in hopes that a new us998_30 rom will be released in the future with volte function. Perhaps a bit silly, but it's a preference at this point I think. I would be a bit more ambitious but I use Google pay and AirWatch daily, so I can't accept the risk that these apps might break with root and an unlocked bootloader.

I don't have an answer either, but this is what I've done too. The official VS996 ROMs have too much junk for me, I'd rather start with the US998 and forgo VoLTE.
I went from US99830B to US99630C to get VOLTE. But after reading this thread,
I did a clean install of US99820H but after initial setup, when I accessed Advanced Calling in the settings, HD calling is greyed out.
