My question/problem. What/why do I have a good 4 bars (of 5 bars) of data signal normally, but, when I decide to dial and make a telephone call, the signal strength goes to barely one bar as soon as I hit the dial button on the phone? I have not moved myself or the phone's location. The call may dial, but goes in and out and, more often than not, drops the call. At the same time, if I receive a call from someone, it is normally a much better signal, and does not drop or go in and out.
I am on Verizon phone (vs996) Frankenstein to us998 30b (pie). I have recently tried android 10 roms (Havoc, POSP). I don't know if that has anything to do with it or not? Very frustrating when trying to call someone.
Any thoughts or explanations or, hopefully, fixes?
Thx

If you are using Verizon on US998 firmware, then you don't have access to VoLTE (which is phone calls over LTE, Voice over LTE). LTE started out as a data-only service but for actual phone calls, carriers were still using 3G HSPA or CDMA (Verizon, Sprint). When making a phone call, phones temporarily bump down to 3G, and then jump back to LTE after the phone call is over.
With the VoLTE protocol, that finally allowed phone calls with LTE. It added VOICE capability to LTE.
However, different carriers treat VoLTE differently. T-mobile allows VoLTE and Wi-Fi calling for US998 phones, while AT&T and Verizon are more stingy. They reserve VoLTE mostly for their branded phones running their carrier firmware.
I'm an AT&T customer and I've never had VoLTE because I've never used a branded AT&T phone. For me, on AT&T, when I make a phone call I am bumped down temporarily to AT&T HSPA. Then, after the phone call, it jumps back to LTE.
If I were to flash the AT&T TWRP flashable zip, possibly I could enable that. But it's not just firmware, it's also a setting on the carrier side that has to be enabled.
Bottom line, what's happening is you are seeing you STRONG LTE signal. But when you make a phone call, you are being temporarily bumped down to Verizon CDMA. However, Verizon is in the process of dismantling all their CDMA towers. That's why your CDMA signal is so weak. Verizon plans to shutdown CDMA entirely by end of 2020. After that, you will need VoLTE to make phone calls on Verizon.
Since you have an actual VS996, you can flash the VS996 TWRP-flashable zip. Once on that firmware, see if VoLTE is enabled on your account (carrier side setting) and see if when you make phone calls you stay on LTE and are not bumped down to CDMA?
Thx, Chazz. So, it's a Verizon thing? Not necessarily something I caused by going back and forth trying out the different Android 10 roms. Good to know. I will try the 996 rom later today, since I don't need the Hotspot for a couple of days. As always, you've been very helpful, thx. :good:

Yes, especially if you see strong LTE signal before making the phone call. Control freak Verizon (mostly) only allows VoLTE on Verizon firmware with Verizon branded phones. There may be exceptions (maybe Pixel phones?) and I know the ZTE Axon 7 (not a branded Verizon phone) somehow got VoLTE not only on ZTE stock firmware but also on LOS ROM -- but I believe ZTE paid Verizon to allow that. It's the exception that proves the rule.
Here's a a more in depth article about Verizon CDMA being shut down end of this year.
https://grantcountyreview.com/content/verizon-wireless-postpones-its-shutdown-3g-cdma networks
when Verizon closes its 2G and 3G networks at the end of 2020, 3G phones will become obsolete and non-VoLTE LTE phones will not be able to make or receive calls.

You DO have a Verizon VoLTE capable phone -- a Verizon VS996 -- but for V30 only on Verizon firmware. If you were using T-mobile with US998 firmware, you would have no problems with VoLTE or Wi-Fi calling. T-mobile is more open than Verizon about such perks.
I don't get VoLTE with AT&T on US998 firmware, but AT&T has no plans to end 3G HSPA anytime soon.
Chazz, I thought I would give a quick update. Late Last night/early this morning, I switched to vs99630c. I have made two phone calls, one to Florida, one to Washington state. Both connected and sounded so much better than when with the us99830b Rom. Even though both dialers had a little HD in the upper left hand corner. This Rom kept the same 3 or 4 bar designation for the signal strength. Much happier with it. Even though I don't have a hotspot (may have to pay the $10(?)or so to set it up, if I decide to stay on here.
Also, I have just seen a 99630c debloated Rom someone has made, that I might try in the next day or so.
I so wanted to try the android 10 Roms, but I just had too many small issues (reboots, no hot spot, system ui crashes, etc.).
Thnx, again for your help and guidance.

Then you are now probably using Verizon VoLTE, which is using LTE signal -- not the increasingly degraded CDMA signal Verizon will completely shut off December 31, 2020.
Verizon is probably already deprecating those towers -- leaving just enough, like when you're on the highways.

I really want volte and vowifi for my unlocked us998. The only way to have that is to flash the vs rom, which is 30c? I'm on US99820h, what do I lose by going to the vs rom? Is there a vs 20h variant?

Yes, we have Oreo VS996 KDZ. It's actually "20k", because it took Verizon two attempts to fully release LG V30 Oreo. And they released a couple extra updates for Verizon related bugs. So, although it's equivalent to US998 20h, it's a higher letter.
https://forum.xda-developers.com/lg-v30/development/vs996-lg-v30-verizon-vs996-t3865398
You need to have VoLTE enabled in your Verizon account, besides flashing this firmware. It helps to have it already enabled from a Verizon branded phone. But sometimes a helpful store rep willing to bend the rules can do it for you.

I misread, somehow thought the ROM you linked was Pie. My bad. I know dirty flash is never recommended, but could I get away with it here? What do I lose by going with the VS ROM over the US998? Apparently the only things I have to gain are VOLTE and possibly VVM?

Do you have VoLTE already enabled in your Verizon account?
You'll lose the no bloatware experience, but you can fix that with Titanium Backup.
As for dirty flashing, you can try... If it doesn't work, then you have to factory reset and clean install. Don't forget to reflash Magisk.

Seems like, yes.
I had to do a few steps to manually activate HD/VOLTE on my VS996 phone when I was on VZ. I documented the steps somewhere here (using ShortcutMasterLite). I know at least one other member here used the same steps on his phone. I'm thinking you'll be fine once you're on VS996.
I have not switched to Pie... still running Oreo. I have heard too many issues with Pie, so I have no desire to bother. I can't imagine VZ's Pie release is any better than Pie US998. VZ is too lazy to do anything else right, so why would they bother fixing what's wrong on US998.
Just want to quickly update this thread. I dirty flashed the VS99620K.zip in TWRP, then immediately flashed the latest Magisk zip. Everything updated perfectly, installed about 10 VZ apps, and I now have VOWIFI (and can send/receive texts!), though haven't been able to check VOLTE as I'm currently in a dead zone.
I'd already had HD calling active on my account, but can't select the option to also enable Video Calling. It says I need to contact support. I chatted multiple times with VZ support who claim it's active, though every time I try to enable it, it gives me the same error. What is this option, and do I need it? I'm pretty sure I was able to use Duo, Skype, Zoom, etc before the ROM update, am I spinning my wheels here?
Also, independent of this upgrade, my motion GIFs in any text app don't move. I thought it might have something to do with the non-VZ specific kernel, but after flashing, still just shows a static picture.

Are you the account holder? Some people can't get to it as they are just user.
https://community.verizonwireless.c...video-calling-feature-is-disabled/td-p/853001
I'm not sure what Verizon video calling is. I'm guessing some Verizon-only video chat -- like Apple's FaceTime is only for iOS? If you are already using Duo, Skype, Zoom, it would seem you don't need it. But you do make sure you have voice over LTE (VoLTE, called "HD calling" Verzion) --before end of this year.

I am the only user on this account, so definitely the account holder. After more wasted chats with VZ, they said that since my phone is not VZ branded, it's not eligible for Video Calling, which apparently is exactly as you described; Facetime for non-iphone Verizon users. I don't need that, as you said all my other platforms work fine.
How do I determine if VOLTE works? Like I said, I'm in a dead zone now, but going out to a good cell region in a few hours and can check then somehow. I did confirm that I can make calls and text over WiFi, so that's half the battle. How to check VOLTE?

I think if you have Vo-WiFi that means your VoLTE is also activated. They seem to be packaged together.
If you make a call in a good signal area, see if the "4GLTE" icon stays on when you make the call. It may even change to VoLTE icon? or HD calling icon? A Verizon user can probably tell you better. But the key is to see if there are any status bar icon changes and what they are. Also see if there is any information in the dialer GUI during the call, where you click on the dialer timer.
Yeah, don't talk to VZ. They're too stupid to help and downright liars. Your phone will work fine on their network even if it's not VZ branded (I've used US998 and H931 phones on VZ without issue).
On my phone, I did have to do some setting changes in SML (ShortcutMasterLite) to get VOLTE working. I don't think most people have to do that, but I did... and I agree, I think that got VOWIFI working as well. I'm guessing you have both, too... just need to try it. If not, you can force-activate it as I documented earlier (via SML).

I'm probably jumping the gun by asking this question now, before the US998 is available, but I'm chomping at the bit to know...
I'd like to buy the unlocked version of the V30, but I understand from the other forums that I may be giving up:
- Verizon HD calling
- Verizon video calling
- wifi calling
- visual voice mail
In trade I'd be getting:
- potentially 128GB internal storage
- no VZW bloat or branding
- all of LG's backgrounds (a reviewer says big red disables many)
- maybe a working FM reciever (?)
Some of these are important to me, some not or can be replaced.
Can you think of any other differences I should be aware of?

You'll get Verizon VoLTE -- but not Wi-Fi nor video calling.
Yes, you can have Verizon voicemail.
Those answers are based on the carrier unlocked LG G6 US997 released earlier this year, from people who have it and use Verizon. You should go over there and ask some questions. That will be the best predictor of the LG V30 US998.
I pasted some of the answers from actual users below.

Getting unlocked phones working on Verizon is still more difficult than it should be. Hypothesis: reps at the local stores don't get a commission on unlocked activations and do get commissions on carrier phones. If you want to avoid technical stuff suggest calling Verizon and threatening to switch to T-Mobile if they can't get it to work, do not go to local stores.
Regarding voicemail, I went with youmail from the play store. You might also be able to get the Verizon voicemail app working, I did not try that since I do not want any lame carrier apps on the device.

Regarding the fm radio. My Verizon branded G6 has the fm radio enabled, you just need to plug in headphones. It works with NextRadio and the LG radio app that I know of. The Verizon version needed files pulled and edited from xda forums to get LG's app working as it does not come with it preinstalled. It wasn't hard to install. An install of NextRadio from the play store just worked. The unlocked version probably includes the LG fm app. NextRadio is pretty snazzy, while the LG App is pretty bland and basic.
I've worked my mind around most things rooted vs unrooted and the biggest problem I have right now is not being able to turn on hotspot on my unlimited VZ plan. this could cause me to return the VZ version if root is impossible which it appears to be. although rooting a phone and playing with it will wipe out the battery prematurely. I've noticed this over and over. not sure I can live without the hotspot option. will absolutely not pay more to VZ to use my own existing plan.

Rooting a phone has nothing to do with battery life. It's just becoming admin of your own phone. The owner of the phone.
Rooting a phone will let you use your hotspot without carrier's permission.
If you mean custom kernels might favor performance over conserving battery vs stock kernel, you have a point. Which might make you have to charge battery more frequently. Thus shorter battery life over a several years period..
However, that is changing! Newer CPU governors like Alucard do a very good job of balancing performance and battery.
One thing you could do is root and run stock firmware, with an xposed module or app that will let you have your hotspot. Again, root by itself does not affect battery life.

LOL.... trust me. viper4android, hotspots, trying all sorts of mods, and yes messing with kernels, changing OS every other week... battery life will get shot... every time, so yes it will... just comes with the territory.
regardless of how you try to fine tune the kernel to conserve. but I'm ok with all of it. I will just be bummed not to get the $200 card and the VR thing. So I guess I have to decide in the next 6 days how important hotspot is vs $300 worth of stuff.

no. it did not. I'm jimmy rigging it by using the wifi extender to trick the hotspot to working but it requires that you connect to a wifi first. data isn't needed on the connect. it's hokey but works almost all the time. so I am now content. LG disabler squashed everything else so the phone is pretty snappy.

Having only used rooted phones for the past 10 years or so, I had a similar quandary, although some of the particulars were different. The arguments in favor of the VZ branded phone were earlier release date, wifi calling, $200.00 discount, and EARLIER RELEASE DATE (I have a thing for immediate gratification). The arguments in favor of the US998 were choice of handset colors and the most important factor: ability to root.
I opted for the VZ LG V30 and have been very hapy so far. As far as the OP's concerns, I can say that the ability to insert a micro SD card eliminates that need for internal storage in excess of 64gb, which is plenty anyway. Also, the LG package disabler (https://forum.xda-developers.com/lg-v30/how-to/guide-make-v30-faster-smoother-t3693083) and the FM Radio apk (https://forum.xda-developers.com/lg-v30/themes/lg-fm-radio-app-download-verizon-v30-t3689294) resolve the bloatware issue and FM receiver issue respectively.
As far as my concerns, the LG package disabler also accomplishes some of the same goals that for which I would want to root my phone. One of the main reasons that I root my phones is too be able to block ads, and I have accomplished that by disabling Chrome and installing Samsung internet beta, as well as by supporting developers by purchasing ad free versions of the apps which I use frequently or finding ad free versions of apps when they are available.
I've mostly gotten over the fact that my phone is silver, especially since it's always in a case anyway.

I have friends who are required to have carrier-branded phones and who cannot root. That's a well written post I'll share with them.
As for color choice I'm hoping LG will sell us the "open market" US988 in black V30+ configuration (or V30+ at all), but I'm becoming skeptical.
Interesting counterpoint, al4d.
There's also the matter of OS update timeliness. And security updates -- do they ever come from the the manufacturer? It seems like only carrier-specific releases get the media buzz.
Lastly, I'm sort of holding out for the Oreo release, just to ensure LG put all their best efforts into it. It would be a shame if 8.0 lands and it's a half-baked mess full of bugs.
Hey @ChazzMatt
Recently I've noticed that I have petty crappy signal and trouble with getting a GPS lock. I remember from the turbo having to flash a modem.
I'm running Stock LG at the moment purely for the camera, is there anything you recommend doing? Ive noticed I cant even change the apn settings.
When I hacked from US998 to VS996, I saw there were more "bars" being shown. Note, however, that "bars" can be changed to reflect different signal levels, so it may not actually be getting more/less signal. If I were careful, I would have looked at the numeric signal, but I missed checking that.
I'm running VS996 on our phones now, partly because of the VoLTE support as well... and all of that is working, so that's good.
I don't think you can flash just a "modem"... but I am interested to hear if this can be done...

Oreo now locks you out of APN settings (it knows what best, supposedly) but you can use an app Shortcut Master or Shortcut Master Lite to manually edit APN settings. Here's how to edit APN using that app. Of course that is NOT the V30 -- but it's still the same technique, and you would want to populate with your own APN information, not what they are using for their carrier. Here are instructions for Verizon on LG V30, at least for MMS.
As for modems, I know there are AT&T and Sprint TWRP flashable modems posted, but not sure about Verizon. You can fire up LGUP and manually flash VS996 modem partitions via DL Partition method, if you want to try that modem. Just UNcheck all partitions except for modems.
Hey guys,
After using my V30 for a few days I realized I couldn't make or receive calls. This is weird because everything else works. The carrier is cricket.
I suspect a VoLTE configuration issue, but I don't know enough to dig into that.
Here's everything I know:
Old phone works with same SIM
SMS, MMS, and LTE data all work on V30
when placing calls, phone just says "calling" for 15-30s before showing "call ended"
when receiving calls, caller hears ring before going to voicemail
phone is new H931 frankensteined to US99820b/20h (have tried both)
Have tried reboot/reset several times
Cricket support was not much help and I don't have high hopes for LG support. Anyone experience a similar issue with their V30 or know enough about the secret menu to troubleshoot?
Thanks
I have had the US998 for 9 months and have had similar issues. I also have Cricket and for the first month, before I even rooted it, I had great service with the phone. Then I unlocked the bootloader and rooted it... Ever since I've had poor reception with the phone almost anywhere, especially when indoors. I have fine 4G internet speeds but have to go outside to make any phone call. I'm currently on rooted stock Pie through TWRP zip but I've tried countless Oreo roms, stock included, but the same problem has been with the phone for the past 7 months. I've tried every APN setting there is but keep in on global normally. Is it possible that we've messed up our modem partition? I'd think Cricket would use the same LTE bands as AT&T but I could be wrong.

I have no problems with AT&T signal on my rooted US998 V30+.
No, you haven't messed up your modem partition.
I have AT&T Prepaid. The only difference between that and Cricket is I have actual AT&T data servers (vs Cricket data servers) and my speeds are not capped. You're never going to see the speeds I have, because AT&T caps Cricket at 8mbps.
Why are you using "Global"? You should be using settings similar below: GSM/HSPA (sometimes called WCMDA)/LTE. Don't confuse "WCDMA" with "CDMA". They are totally different. WCDMA is HSPA, if you don't see HSPA in your settings.

1) Check your APN. Make sure it's set to what you need for Cricket. Google Cricket APN.
2) You are not currently using AT&T firmware, so you will not have VoLTE. You need to turn VoLTE off in the settings if you see it. AT&T only allows certain phones on Cricket to use VoLTE -- and you currently have "US998", not H931.
If you see VOLTE setting turn it off, see if your phone calls can be made? Trying to use the VoLTE setting when you aren't allowed VoLTE will cause phone calls to fail.
If you bootloader unlock your phone and re-flash the AT&T H931 TWRP flashable zip, it's possible you get VoLTE IF Cricket is allowed VoLTE on H931 phones. Many AT&T postpaid customers are using rooted, bootloader unlocked H931 phones and have VoLTE because they flash to the H931 TWRP flashable zip.
What was your previous phone? Just saying your "old phone" tells us nothing whatsoever. Was it AT&T branded?
Are you sure you had VoLTE on your old phone with Cricket? Or you just assume you did? If it was an iPhone, then it's possible you had VoLTE on Cricket. If it wasn't, then you may just be assuming you did. I'm not current with the phones which have VoLTE with Cricket, I just know it has been very few.
Because AT&T keeps VoLTE as a premium feature -- although they have been giving it to more phones recently. But still usually with AT&T branded phones (which my US998 V30+ is not). I do not have VoLTE on AT&T Prepaid with my US998 -- and I couldn't care less.
You don't actually need VoLTE. When you make a phone call your phone can drop down temporarily to HSPA while you have the phone call and you will still have data. When the phone call finishes your phone will then return to LTE.
I have AT&T Prepaid, as does my wife and my mother -- and all our US998 V30/V30+ phones do exactly that. We do not have VoLTE and don't care.
See screenshot. If you find this setting, turn off VoLTE see if you can make/receive phone calls until you can flash the H931 TWRP flashable zip. But also find out if AT&T H931 can use VoLTE on Cricket.
LG V30 AT&T H931-20Q ROM
https://forum.xda-developers.com/lg-v30/development/lg-v30-att-h931-20f-rom-t3872926
Thanks for the detailed response.
My previous Cricket LG M327 definitely has VoLTE on Cricket per this list:
cricketwireless[dot]com/support/great-big-network/compatible-phones.html
There's also a settings option for it, and I can tell the difference between calls with/without.
If AT&T considers it a premium feature, you're probably right that it's limited to branded phones.
On my V30 I don't see an option for VoLTE in the option menu. I also don't have nearly as many options for mobile network mode as you do.
I will try flashing H931 to see if that changes anything.

I did check that. All correct.
I went to try it this morning and suddenly it worked on US99820b. I refurbished to 20h which is the version I want and switched to LTE/GSM network mode and it works.
Thanks for your help.
It worked for a day or so, then stopped working again. I think the issue is that Cricket is trying to provision the phone for VoLTE, but then their backend won't actually allow this IMEI to make VoLTE calls. I obtained an active SIM on another carrier and confirmed that the handset can make/receive both VoLTE and non-VoLTE calls.
Do any of you guys know how to disable VoLTE via adb/hidden menus? There is no option in the normal Settings menu with the cricket sim installed. My other option is to switch carriers.
Folks,
I know there's a mixed bag of posts among a bunch of threads that cover how to get Verizon VoWiFi/VoLTE and HD calling working with a US998 variant device and I've had success with those elements but in the process, found that Hotspot gets broken.
So, here's where I'm currently at; both VoWiFi and Hotspot are critical needs for me.
I have a Frankensteined LS998 that, on a purebred US998 ROM, Hotspot works flawlessly but VoWiFi does not and I've not had any success in getting it too either.
I ended up switching back to a purebred VS996 ROM and now have VoWiFi working but Hotspot functionality fails at the "You need to subscribe" lock out message.
I have tried to isolate what specifically is different between the two ROM's that would trigger Hotspot to fail like this in the VS996 ROM but have not had any luck.
I've played with a ton of settings via Shortcut Master, compared all the files in /system/etc/dsts/joan_vzw_170626 and tried "DF Tethering Fix" and a bunch of other random stuff based on bits an pieces I've picked up all over the web but am still coming up short.
Ideally I'd like to get VoWiFi working on a US998 ROM and, just for kicks, tried these steps https://forum.xda-developers.com/showpost.php?p=76613814&postcount=391 but it appears there is still some key VZW software missing.
It feels like getting the Hotspot working on the VS996 ROM is perhaps just something like an APN setting away (yes, I've tried adding DUN to the APN's list with no luck) so I'd be happy with either solution.
One thing I haven't tried is just flashing just the VZW modem to US998 to see if that may just bring the VoWiFi pieces across without compromising Hotspot but before I do that, I wanted to pose the question to the knowledgeable folks in these forums in case someone already has an answer or suggestion for me.
Is there anyone out there that's had some luck in this area?
Cheers,
Windza
Like you, I tried the mixed bag of techniques posted across forums to get VoWIFI going on my US998. I have also crawled hidden apps using Shortcut Master. Although there were glimmers of hope, none of the methods gave positive results.
I do have a pair of identical V30's and have thought about doing a side-by-side comparison to see if I can find the difference. One might be the Settings app itself. The bottomline is that I just don't have the time anylong to go down these rabbit holes and my will to battle with LG is attenuating rapidly. I do not need VoWiFi but HotSpot is a must so I am mostly content using the stock US998 Oreo rom.
BTW, if you want unthrottled hotspot bandwidth on Verizon, go into the APN settings on the phone and switch both APN Protocal and APN Roaming Protocol to ipv4. Then switch the ttl from 64 to 65 on any computer or device that will connect to the hotspot.

Thanks for the response... glad to know I'm not alone on this.
In fact, I lol'd at you having identical V30's and considering looking at them side by side.
I happen to have 3 identical LS998 variants (1 with shattered screen, 1 with US998 ROM and 1 with VS996 ROM) and was sitting at the dining table yesterday doing exactly that with the 2 good phones... trolling through Shortcut Master/IMS/APN/PDN etc.
As you said, glimmers of hope but no positive results.
I found myself frustrated at my own lack of knowledge and experience with cell networks and then even really finding anything solid on the internet.
It seems like there's almost a black hole or void out there on the nitty gritty of cell network setups (perhaps it's unique per provider and considered proprietary/IP?).
It feels like the answers exist in understanding what the settings mean and using the right combinations but I'm with you in that I'm already time short and my resolve is nearly run out...
I'm going to try flashing the VS996 modem to the US998 ROM today... will report back when I know the result.
Can someone at least tell me what APN types like ia, ims, dun etc. mean specifically or point me in the direction of a resource that might?

Aaaaaand... the result is unsurprising. I know some folks were reporting anecdotal improvements after flashing the VS996 modem into US998 but I'm not seeing notable difference from where I was already at.
I was on US998 20e and flashed modem from VS996 20f but no luck... last resort is to try US998 20h and VS996 20k but I'm not holding my breath.
No matter what I override in the background, the consistent element on the US998 is the two switches in the attached s/shot are grayed out and unable to be toggled on (even though their equivalents in the background are on).
As soon as I flash a VS996 ROM, these switches can be toggled to get things working.
I will be of no help... But I'm definitely interested in this!
I've got US998 running vs996 stock pie with full functionality of Hotspot and vowifi. One thing I noticed when debloating my install was that removal of the Verizon phone app would cause the phone to not boot, so my guess is their app is one of the pieces of the vowifi puzzle.
Has anyone tried running Verizon phone app on a US998 Rom?
I am in the exact same boat.
Currently running US998 on Verizon VS996 only for hotspot. I also tried to get VoLTE running via https://forum.xda-developers.com/lg-v30/how-to/wtf-lg-v30-t3790500/post76613814#post76613814 but no luck. Was able to get the Verizon app to run but it didn't help with VoLTE. Possibly because I'm on a corporate plan so I don't have many options available in the app. Also missing RCS messaging features which I had on VS996 ROM, but maybe I need to try the "beta versions of Messenger" trick.
I also tried copying the HotspotProvision.apk and odex from US998 to VS996 rom but no luck there either.
Yet-another-'I want this'-reply. I use my phone for, in order, Tethering, maps, and phonecalls, and it's frustrating that using Verizon as a carrier means we have all sorts of compromises when it comes to functionality because they are supporting ancient network tech.
I'm just worried that in a world of folding screens and bull**** edge displays, actual good devices like the V30 are going to fall apart in the dev community. If we don't have a fix soon, I'm expecting never to get one.

See my parenthetical comments.
That answers your question. Your hotspot would work on Verizon firmware IF you paid for it, like they want. There's no mystery.
Whereas on US998, Verizon has no control over how you use your data. You get "free" tethering feature on US998 firmware.
But on US998 Verizon still has control over whether to grant Wi-Fi calling to devices on their network, and they decline to do that. Control freak Verizon makes you be on Verizon firmware for Wi-Fi calling to "encourage" you to buy their hardware (even though you didn't).
T-Mobile doesn't care and grants Wi-Fi calling on US998. So, it's not "Wi-Fi calling" issue -- it's a Verizon issue.
The difference between the two "ROMs" is one is based on firmware certified by Verizon and the other is not.

Get a V30. Heck, get a V30+! You can have tethering, maps, phone calls on US998. What you cannot have on US998 firmware with Verizon SIM card is Verizon Wi-Fi calling. T-mobile allows it, but Verizon doesn't. But you still get phone calls.
My sister and brother-in-law are both on US998 firmware (former LS998 V30+) on Verizon and they both get VoLTE.
$110 for mint US998 V30+.

ChazzMatt, here's the kicker - that seemed like an obvious and logical argument to me initially as well BUT I had issues initially with not having any of the good stuff on VS996 and ended up on the phone with Verizon.
They assured me that my phone was provisioned for everything but my SIM card was very old (true) and potentially the issue... something about it being issued well prior to VoWiFi being rolled out (likely also true based on quick Google search).
This seemed like a real stretch to me but I ended up at the store with a real decent Rep/Tech (surprising I know) who confirmed that my phone was provisioned for everything but, nonetheless, also thought the SIM was a stretch to resolve the problem.
Fast forward past him having a ton of issues with my account and nicely gaming a bunch of stuff to work around their system (using IMEI/MEID's from the recycle box... lol, I tell the truth and was impressed/shocked); I end up with a new SIM but still have nothing working and he is out of answers as well.
I came back home and started massaging settings via Shortcut Master and eventually got VoWiFi working but came up short on Hotspot which is where my OP came in.
My OP skipped this detail because I thought it was fluff but, to circle back, there may be something relevant in that for the local Rep to have to game their system might suggest Verizon has a technical/provisioning issue with my device.
It wouldn't be the first time I've had a major Telco screw my services up... (I once ended up with a $12K bill in Australia due to Telstra setting my 3G phone up for old school 2G data access which was billed at ludicrous rates - ended up resolved amicably tho I had a major initial flipout).

My brother-in-law (who could sell snow to Eskimos) and my sister recently switched from AT&T to Verizon with two former LS998 V30+ converted to US998 V30+. NOT bootloader unlocked. Just stock phones.
Yes, "US998" with Oreo 20h are carrier unlocked phones (with CDMA and LTE band 13), but I know you need an already-activated Verizon SIM card. Verizon is NOT going to activate a SIM card on former Sprint LS998 V30+...
But my brother-in-law found a store rep willing to help. The guy said, "They will tell you this phone doesn't work on Verizon, but it does." He activated two SIM cards for them, let them go drive to their neighborhood and test them out. They are switching to Verizon because the upscale neighborhood they are moving to has an AT&T black hole. Only Verizon works there. (Even AT&T microcell doesn't work well, because of size of the house and thick walls. And they don't get AT&T Wi-Fi calling because it's not AT&T branded hardware.)
Any great Verizon signal. Not sure if the rep provisioned VoLTE or not, as I haven't touched the phones recently. But they are very happy. The guy told them, "If something happens and you need help, come to the store and ONLY SEE ME. Don't tell anyone else what I've done."
Nice to find someone like that, but my brother-in-law is GREAT about finding people like that. He's a very successful salesperson and knows how to make people WANT to help him. What's really scary is when he turns his skill set against other salespeople. You should see him when shopping for a car.
"What color are you looking for, sir?"
"Doesn't matter, it's just all sheet metal to me. Color isn't important."
When he really has his eye on that cobalt blue SUV or whatever...
"Oh, that one? I guess I could drive that if you've got nothing better."
When he gets finished, it's like they've been hypnotized.
He walks out with exactly what he came to get, and at fantastic price.
I'm pretty new to both rooting and this website, so I apologize in advance for any newbie mistakes I'm gonna make.
Background:
I have a VS-996 which frankensteined and unlocked by following this post . After doing that I flashed pie and then flashed lineage os from here . That rom wasn't very stable and kept crashing, so I tried others. I wound up going with Havoc OS. I believe it was in 3.4 when I first flashed it. I've kept up with the updates up to 3.7.
The Problems:
Havoc OS works fine for me, very stable, except for some reason phone calls and messages(both sms and MMS) are spotty at best. Sometimes texts won't send at all, or they'll act like they sent but the text won't be recieved. Sometimes my phone will say I can make emergency calls only. Group messages and sending pictures don't seem to work at all, at any time. These issues seem most prevalent immediately after booting my phone up. Data works perfectly except sometimes when the phone doesn't like to register that the SIM is inserted for a little bit after booting up.
What I've tried:
I've tried reinstalling the rom.
I've tried installing different Android 10 roms.
I've tried going through the process again starting at the the Frankenstein method and going from there.
I've tried messing with the apn
If I flash back to a stock pie ROM everything goes back to working perfectly, and I'm using my sim in my old V20 while I try to sort this out, so I know the SIM is not to blame.
I've been unable to find anybody else with this particular problem, though that could just be because the problems cover so many different aspects that I'm not sure exactly how to search for answers.
Any help is appreciated, thanks.

Are you Verizon customer? You say you have VS996.
There's an LOS ROM bug for Verizon SIM card users where upon rebooting the phone you have to make a phone call first to then receive texts. This phone call "registers" the SIM card or whatever. Many people call their voicemail number to satisfy this requirement.
This bug affects all LOS-based ROMs.
Yes I am a verizon customer. I had noticed that making a phone call seemed to help things along when messages wouldn't send. I guess I managed to let my phone die or turn it off enough to hide the fact that it fixed me. Giving it a test just now it seems to be working correctly. I don't know if I'll be happy or mad if the solution turns out to be this simple.

I don't know if I'll be happy or mad if the solution turns out to be this simple.

Was noted extensively on LOS-16 ROMs, but not discussed as much with LOS-17 (Android 10) ROMs. But earlier this month someone in the Havoc 3.7 (LOS-17 based) thread did bring it up...

However, the larger problem is in six months you will not be able to use LOS-based custom ROMs with V30 on Verizon.
* As of December 31, 2020 Verizon is dropping 3G CDMA to repurpose bandwidth for 5G.
After that date, to make any phone calls on Verizon you will need VoLTE. No LOS-based custom ROMs have VoLTE. You will need stock Verizon firmware. It can be rooted stock firmware; you can use Magisk modules to add features -- but needs to be Verizon firmware for VoLTE.
* T-mobile users are in the same predicament.
In January 2021, T-mobile will be dropping 3G HSPA for same reasons. T-mobile users will need VoLTE, which only comes with V30 stock firmware. However, T-mobile is less stingy. They also allow US998 firmware to have VoLTE and Wi-Fi calling with T-mobile SIM. Whereas Verizon requires Verizon stock firmware, and it needs to have been activated on a phone with Verizon IMEI at some point.
* AT&T will also eventually drop 3G HSPA -- but not until February 2022 (18 months from now).
So, for U.S. V30 owners who wish to run custom ROMs a little longer, you should check out AT&T Prepaid. It's a lot cheaper than "regular" AT&T, but is only for people who own their phones.
18 months is a long time. Anything can happen in 18 months!
AT&T only gives VoLTE to AT&T IMEI phones, as well as iPhones and some other phones I would never own. I've never used an AT&T branded phone on AT&T. I'm an AT&T customer with three native US998 for myself, my wife, my mother -- so I'll cross that bridge when I come to it in February 2022. Will probably give my mother an AT&T V35. Maybe my wife, too. Also, LG may get their act together and produce a good phone fro the LG V70 or LG V80.
Any Verizon, T-mobile (and Sprint), and AT&T MVNOs (Straight Talk, Ting, etc.) will also be affected by these decisions.
I have a more extensive discussion of this issue here:
All U.S. V30/V3O+/V30S will need stock firmware, not LOS-based custom ROMs. When?

I am on red pocket service. I just received an email stating I do not have VOLTE enabled and may lose service. Supposedly, I should be able to enable VOLTE. I reached out to customer service in the past and they stated it is active on their side. Their website says I should be able to see it under settings -> mobile network; but I see not options for VOLTE. I have had **** service the past few months, with texts not being sent despite it showing bars or texts incoming taking a while; I wonder if this is related. Can anyone please help me?
I am on Android 8.0.0
Kernel 4.4.78
Version: US99820h
If it helps, VoLTE plus app says VOLTE is enabled. Do I need to be concerned? Is there any reason my service seems to run like crap? It's red pocket GSM-T. Had many people tell me calling me goes straight to voicemail, I get texts late, for confirmation texts I often have to restart the phone to get the texts to come through... Any fix to this? Should I switch to a different image and go onto a different set of towers/service?
Many V30 phones require the carrier's ROM to operate VOLTE. For example, when I was on Verizon, I had to have VS996 to get VOLTE to work. I also used it on Total Wireless (which is a VZ MVNO) for the same reason.
I'm guessing your GSM-T means you're on TMo, so you may need a TMo ROM to get VOLTE to work. US998 is a world-phone ROM, so it's not carrier specific, which may be why it doesn't work.
As for the general operation, you should be fine on US998 for all other functions... so if you're having issues then there may be something else going on.
You might also just need some updates - 20h is nougat level, which is ancient. You may need to move to Oreo... which worked great for me on my V30 in the past.

So, do you think I would need switch to a newer ROM, specifically for tmobile? I have been on us998 since buying it, always had some issues with texts coming in late and connectivity (although not as bad as when I had a S5 on Ting's t-mobile network). I had called and been told VOLTE is active with red pocket twice in the past, but despite always being on wifi I've still had people tell me I do not always come in clear when talking on the phone.
Can you point me to a newer ROM you used? I can try updating and messing with the phone later this month.
You can't use my ROM (VS996), as it was for Verizon. I doubt that will work for you. You need to find the proper on for your carrier (TMobile most likely) and see if that fixes the issues. All my ROMs I sourced from this website/forum, so you just need to search the V30 section here.
Note, when switching ROMs, you will need to wipe it so be prepared with backups for your data.

Just be careful NOT to flash H932 ROM on your device, it will brick your phone.
You could try updating to us998 Pie ROM and see if it helps.

I saw chazzmatt mention in another thread that when t mobile and sprint merged, VoLTE/VoWiFi calling on US998 firmware phones may have been lost. He suggested that changing to verizon version is a way to fix this. Is this something I may have to do? And is there a guide on how to do it? I only see switching to us998.
And this would this be the rom to flash to for android 9?

@ChazzMatt is the resident expert, so you can certainly take his advice. I saw that post as well.
Converting to VS996 just means you will use LGUP to flash that ROM over your current one. The end of the WTF post/thread talks about this process as well (be sure to read that post on a computer, as phones often cut-off the bottom).
Note that this will erase your data, so backup/etc as necessary before doing that. My recommendation is to use the last Oreo version of the ROM, as Pie on VS996 had issues last time I had heard... that's the last ROM I used before switching to my other phone.

And in doing so, they still need an already-activated Verizon SIM card or Verizon MVNO SIM card. Verizon won't activate a SIM card with a phone that doesn't have native Verizon IMEI. But you can stick in an already activated SIM card into a v30 with VS996 firmware and it's fine. So whoever does this needs to also have an old Verizon phone for that purpose. Buy some cracked screen Verizon phone off eBay, activate Verizon or Verizon MVNO SIM card, THEN put that SIM card into Frankenstein'ed phone flashed with VS9996 (Verizon) firmware.

Are phone numbers attached to the sim? So I would have to: obtain verizon sim card, transfer my phone # while activating a plan on it using another phone, then place it into my current phone after flashing it into VS9996 and upgrading it to 9.0?
Yes, the phone number is attached to the SIM card.
Yes, your steps are correct - activate SIM on some other phone, then put it into the VS996.

Hmmm, perhaps before I spend money to switch to verizon I should try upgrading from US99820h to US99830b using that thread I posted above? Maybe that will fix things for me. I thought I had fixed something when I updated my redpocket APN point, but I still get random loss of service where I live and work at (despite constant wifi). According to redpocket customer service, being locked into 240 MNC sim card does not change anything compared to 280 MNC.
Perusing the us99830b thread, I saw if I have TWRP installed then I must use johnfawk's image to flash. I cannot "upgrade" and keep all my data using the firmware off LG's website with LGUP. Am I understanding that part correctly? And the TWRP image for me to download is this link? Mirror Link
First, my recommendation is to stay at Oreo (20-series) ROMs. Last I recall, the V30 Pie rom had issues that were never fixed.
Secondly, yes, I don't believe you can upgrade the ROM... you will need to flash the full ROM which would erase things. That being said, since you're already converting between ROMs you will need to wipe the phone anyway, so do all the updates/upgrade BEFORE you install anything else on your phone. And, of course, backup everything you need before doing that...

You mentioned before that 20h is nougat level, but my android version says 8.0.0, isn't that oreo already?
Looking at this site: https://lg-firmwares.com/lg-us998-firmwares/
I am already at the latest Oreo software. So, several questions:
1. I could back up all my stuff and risk missing something, but I can also just create a current TWRP image and go back to where I am presently in terms of all my stuff?
2. Should I be trying a https://lg-firmwares.com/lg-vs996-firmwares/ VS99620k version? When I reboot my phone it says it is a LG V30+ThinQ and I vaguely remember the box it came with said LS998 crossed off, with it booting as a US998 phone.
3. I have an old CDMA Galaxy S3 (best phone I've had). Assuming I am able to boot it up, can I buy a verizon MVNO sim card (let's say off of TING), switch my phone # to that and pop it in the S3? Or can I bum someone else' verizon phone and do this, then give the phone back instantly?
4. If a friend has an old verizon sim card, can I use that to utilize either red pocket or ting services?
5. Then, flash this US99820h to VS99620k, swap the sim card out of the S3 into the newly flashed V30?
6. Assuming I do all this and I still see no menu for VOLTE, assuming I still have the same issues of service dropping constantly, any suggestions for moving to a new phone, or what to use to find a new phone? Many new phones seem to have lots of stuff I do not care for (fancy cameras...) and no 3.5mm jack; but I really crave a phone that is functional.
Sorry for lots of questions. But each day this phone is pissing me off more and more and reminding me to do something about it - been busy and have stuff I do not want to risk losing.
I didn't say 20-series was nougat... I said it was Oreo?
1) TWRP will backup everything, so you could use this as a way to "keep safe" what you have now, and maybe you can break into the ZIP and extract things here and there as needed, but I don't think you can use this as a way to restore just your programs/data... it's a whole-image that you need to restore, which includes the OS and such. But if you're already on Oreo, I don't think you need to do any of that?
2) Yes, you can apply VS99620k. I believe that's what I had on my V30 before I left it. I wouldn't pay much attention to the splash screens on bootup... they change between versions but don't really mean/do anything from what I could see. My phone started as US998 (without the "ThinQ" branding) and I believe it showed the ThinQ branding when I was on VS996.
3) Yes, you'll need an activated SIM on VZ to transfer. Yes this is one way to do it. I did something similar with my Droid Turbo. VZ won't activate anything unless the IMEI matches THEIR phone, so this is one way to get that to happen. The trick, today, is that VZ may not activate the old phone because it's not VOLTE capable, so they'll say it's not supported, so that's a risk you should be aware of. For that matter, a newer SIM also may not work on the older phone... I don't know if that's a thing or not.
4) I don't know if MVNOs will let you use VZ SIM cards. Technically, they should be able to, but my guess is they will require their "own" SIM. You'd have to ask the MVNO.
I moved to the Galaxy S10+, which is a similar size phone, has a headphone jack, and is older so it's lower cost (I think I paid $300 about a year or two ago). A few other V30 faithfuls have followed this path as well. I think ChazzMatt went to a Note because that's what ATT gave him to help him transition to a VOLTE-capable phone. I believe he's still using his V30 though.
Newer Galaxy phones lost the headphone jack. I would recommend getting yourself ready for this eventuality... it may mean just getting a dongle, which isn't convenient, or getting bluetooth adapters... but my point is that it's going away whether you like it or not, so start preparing now.
EDIT: I forgot to mention, the S10 is not rootable (at least with Snapdragon). Exynos can be rooted, but I don't know how usable those are in the USA. That's another thing you may need to get used to - not being able to root/ROM. IMO, it's not necessary anymore, and I have given up on it on my phones... and I haven't missed it AT ALL. But I know some have gotten into heated arguments with me over that... one I recall was particularly nonsensical, but whatever. If I could root, I would do that... but I don't see it as a requirement anymore.

As @schwinn8 recommends staying on Oreo, I also concur.
1) If you have TWRP, just flash the Verizon last Oreo by John Fawkes. See link below.
LG V30 Verizon VS996-20k ROM
Working downlink mirror: VS996 20K Verizon TWRP-flashable ZIP
2) If you don't have TWRP installed -- for people who are not bootloader unlocked -- then you would flash full stock ROM VS996 20K "KDZ" file from US998. See top post in this thread. (For those who are still bootloader locked, the stock Verizon ROMs and US998 ROMs are the only ones for North America variants which are safely fully cross flashable without first having to go through the "Frankentein" conversion "Nougat" stage.)
As for spending money on Verizon to get VOLTE, there are several Verizon MVNOs that are less expensive than Verizon proper and will still do the trick. Both Visible and Total Wireless are even owned by Verizon, like Cricket is owned by AT&T.
RedPocket also offers Verizon-network SIM cards. They are also a Verizon MVNO. Which carrier service are you using with your RedPocket? They offer choice of AT&T (most common), T-Mobile and Verizon. I searched your posts in this thread and you don't say which you have -- so I assume the AT&T-linked SIM card? If you flash the last Oreo TWRP-flashable zip for Verizon, and you want to keep RedPocket, just have them ship you the Verizon-linked SIM card. You should then have VoLTE.
NOTE: You would still need to use an old Verizon phone to activate that SIM card, but then you could put it into your "VS996". I'm only suggesting a way to not have to actually switch to Verizon, you can still use Redpocket but have them send you a Verizon linked SIM once you are on Verizon firmware.

Got it, if flashing is all I have to do, this will be simple.
I was not clear, I did mean verizon MVNOs, meant more verizon in broader sense: CDMA. I am currently on red pocket T mobile. I was previously on Ting. Had similar issues on both with randomly losing service. It was bearable, but since 3G shutdown timeframe, this became a larger and more frequent issue. Currently, if I turn on data, I get Edge service (I read this is 2g?), otherwise when I am having a texting conversation, I am regularly losing service completely and do not have strong service in places where other Tmobile users have regular service.
On another note, I am looking to swap from red pocket; I spoke to customer service about call records, was told several times they would be sent to me, never received anything. Red pocket prices are hard to beat though.
I impulse bought a pixel 7 unlocked too (there were some incentives that were hard to resist). So, I will probably swap to that phone while holding onto this one and tinkering to see if it was a phone issue, US998 issue, SIM issue, service issue... then give the phone to family in a year or so.
