[LG V30 Guides, News, & Discussion] TheDannemand:
Glad to hear you got it working.

I suppose the lack of menus and icons you are seeing (or rather not seeing) is why people have reported that VoLTE doesn't work on Pie. It DOES work, and is enabled by default, but there are no menus, so people understandably think it isn't there. I assume you can use the Hidden menu to enable the VoLTE indicator?

And great to have confirmation that VoWiFi works and can be toggled in the menu. Thank you for confirming that.

I understand you are missing features to change e911 info which you had on Sprint. I am guessing that is performed differently for each carrier. I don't even remember seeing it when I had an H932 (TMO V30) on TMO postpaid.

I think you need a carrier phone (or carrier ROM) to get more features than this on a given carrier. US998 is after all an Open Market model, not an All Carriers model.

I wonder if the problem with your account may have been the timing: While you can switch SIM anytime during a billing month, switching network should be done at the end of a month, since the remainder of the month is lost. It starts the new month on the new network.

Good job!
[LG V30 Guides, News, & Discussion] :
The hidden menu method has not allowed the icon to show up on sfaus bar... And there is no icon for wifi calling either... No toggle button for it either...
[LG V30 Guides, News, & Discussion] TheDannemand:
That is annoying indeed. And not the impression I got from other reports of US998 on TMO. Again this is likely the lack of VoLTE on Pie that others have been complaining about.
[LG V30 Guides, News, & Discussion] :
VoLTE worked no problem with the GSMA card though... Just not vowifi

On the call log I am getting a HD icon on the phone icon...is that indication of VoLTE?

Only way I know wifi calling is working is that I can make a call and when I swipe down on status bar I see wifi calling on bottom in place of red Pocket
[LG V30 Guides, News, & Discussion] TheDannemand:
VoLTE works on AT&T/GSMA, but with no menus and no visual indication (unless enabled in the Hidden menu) many people didn't realize it was there. Of course AT&T and most MVNOs didn't provide it either. And no VoWiFi.

The HD icon is a sign that you have VoLTE working, probably VoWiFI too since they use the same codecs. I don't get the HD icon on GSMA except when I tested H931 ROM.

You can look for TMO specific menus with Shortcut Master Lite and relevant settings through the Hidden menu. But make careful note of anything you change, as some of these settings persist even after Factory Reset and re-flash.

It sounds to me like it's all working, just not very visibly. I did indeed get the impression from other US998 users on TMO that they had more menu controls and more visibility. Again, I assume they must have been on Oreo.

It may be by design that Pie doesn't show icons: Since VoLTE/VoWiFi is becoming the only ways to make phone calls, I can see the logic of not putting multiple icons on the status bar to confirm that "this phone can make calls".

You can consider rolling back to Oreo, just realize there is a risk of messing things up. Definitely go via Nougat, and use Partition DL.

I am very busy these days and the next few weeks, so may not be able to respond as much to any questions :(

Edit: If you didn't perform a Network Settings Reset, I'd say definitely try that. Also, you could try re-loading the IMS configuration in Hidden menu. Restart the phone after both.
[LG V30 Guides, News, & Discussion] :
I think I am going to try a fresh install of US99830b, flashing US99810c first to clean things out? Maybe even try AiX again?

I have been flashing back and forth a lot lately so I am not sure if that causes crap to go away too....SystemUI tuner could have caused issues as well....I dont really know how to flash back far enough to get rid of what it could have changed
[LG V30 Guides, News, & Discussion] TheDannemand:
If you're going to do that, I would definitely check US99820h, which is everybody's favorite V30 ROM. Again go via Nougat US99810d first, Partition DL. But BEFORE you leave Pie, perform a Master Reset from the Settings menu. I believe it clears some persistent settings that cannot be cleared once you are back on Oreo.

As previously mentioned (or maybe that was another thread) I doubt Aix has carrier configs for US carriers. But I'd love to hear confirmation either way.
[LG V30 Guides, News, & Discussion] :
I have never heard of 20h. What would be flash steps to use it? Where is it?
[LG V30 Guides, News, & Discussion] TheDannemand:
It's the latest US998 Oreo ROM. You can find it in ChazzMatt's stock ROM threads or download from lg-firmwares.com.

Steps are:

1) Perform Factory Settings Reset from Settings menu in Pie. Again this is to clear any persistent modem settings that Pie may have set, and which only Pie can clear.

2) Using Latest Dev Patched LGUP from one of ChazMatt's threads, Partition DL Nougat US99810d.

3) Restart phone and see its working, Master Reset (button dance) if needed.

4) LGUP Partition DL US99820h.

Of course this ROM is almost two years behind in Android security patches. But it is arguably the best ROM LG made for V30.
[LG V30 Guides, News, & Discussion] :
I havent done that Partition stuff in ages.....So not the 20E to F to G to H steps in there?

20H is after 30b?

Would this be the Nougat KDZ you mean? US99810d_01_0411.kdz
[LG V30 Guides, News, & Discussion] TheDannemand:
You can do the incremental upgrade steps, but they are mostly for TWRP flashable ROMs, as I understand. I've never done it myself. @ChazzMatt can speak more to it.

20h is Oreo, so definitely before Pie. But later isn't always better. LG's attention was elsewhere (on later models) when they created Pie for V30. And US998 Pie versions are really a US Cellular ROM, whereas Oreo was LG's Open Market ROM.

Edit: Yes, US99810d_01_0411.kdz is the latest Nougat KDZ, while US99820h_00_0318.kdz is the latest Oreo KDZ.

I really have to get on with work now. Good luck to you (y)

Edit2: But just remember, there is a risk associated when going back from Pie. Some people have reported issues. That's why we recommend going via Nougat.

[LG V30 Guides, News, & Discussion] :
@ChazzMatt Will I have to do WTF etc and unlock, root again after I get to 20h through LGup? or am i better off just doing thr TWRP flash progression 20E/F/G/H ....I am on US99830b currently
[LG V30 Guides, News, & Discussion] TheDannemand:
You don't need to do WTF again, your phone will remain BL unlocked.

But when you do a full Partition DL you will lose TWRP. Just go to fastboot and reflash it -- yes as described in WTF steps. US998 has full fastboot on all versions, it's only the BL unlock first time that requires early Oreo.

But you don't need root until you've settled on a ROM. You can test Oreo 20h to see if it works better with TMO VoLTE/VoWiFi. If you like it, THEN you go to fastboot, flash TWRP, flash Magisk etc.

If you DON'T like Oreo and want to go back to Pie, go via Nougat again.
[LG V30 Guides, News, & Discussion] :
OK! Get to work! Thanks!
[LG V30 Guides, News, & Discussion] :
Just tried AiX with RP GSMT....odd crap...Can make calls with Mobile Data AND Wifi off? huh?

Airplane mode and wifi combined nothing
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, exactly. From Pie, you need to go through Nougat KDZ to flush out Pie remnants. Then you can flash Oreo 20h KDZ and reinstall TWRP, etc. Go through SECTION 6 of the WTF instructions.

If you want to enable DTS libs either do it manually, or flash 20h TWRP flashable zip over 20h KDZ after you reinstall TWRP. JohnFawkes already has it enabled on 20h TWRP flashable zip.

Manual method if you want that:

Enable DTS 3D Stereo sound on all LG V30 variants [Root]

The LG V30 update that was rolled out in November mentioned the addition of DTS 3D Stereo. This mod enabled it on all variants of the device.

@TheDannemand

So the drama continues... Couldn't do lgup on multiple PCs etc... Did the twrp progression flash from 10c to 20e f g h...but now we can't get voicemail notifications to work and then to find out from RP after they switch me to GSMT... "oh we don't have visual voicemail" sorry...

I dont get any pop-ups sounds nothing from voicemail even though there are options in menu of 20H...nothing for pop-ups though
[LG V30 Guides, News, & Discussion] ChazzMatt:
Maybe try a different T-mobile MVNO? I don't know if he's getting visual voicemail, but everything else sounds fine.
[LG V30 Guides, News, & Discussion] TheDannemand:
Admittedly I haven't used visual voicemail from carriers for many years since I got Google Voice. It ties into the carrier's voicemail forward and provides visual voicemail regardless of what your carrier provides. I used it on Sprint, TMO and now AT&T (Red Pocket).

Mint was indeed the first MVNO to provide TMO VoWiFi and probably the ones that are closest to native TMO service. Also more expensive last I looked. My wife used them for awhile.
[LG V30 Guides, News, & Discussion] :
They actually seem to be cheaper...plus the techs at Red Pocket with over 15 chats I have had are very unprofessional...
[LG V30 Guides, News, & Discussion] TheDannemand:
You should look into it then. Particularly if they also work better for you 👍
[LG V30 Guides, News, & Discussion] :
@TheDannemand @ChazzMatt I have a question for you guys. I have had a hell of a time with SMS apps. I like NextSMS(Handcent) and have used it forever....but it seems to end up corrupting the process as in today I could only send an MMS and not an SMS.

Details aside, is it possible that a 3rd party app can corrupt the process to the point where I cant even use the stock messages?

I had to clean install 20H again and it works....and I still have the same issue with 20H in that whatever Magisk I use after initial flash it doesnt install root and Magisk Manager UNLESS I go back into TWRP and reinstall...odd
[LG V30 Guides, News, & Discussion] ChazzMatt:
Sorry, don't know about the SMS and MMS. I use Google Voice phone number and still get messages in Hangouts. Although soon I will have to start using the Google Voice app as Google keeps threatening to bork Hangouts.

I also get SMS messages from AT&T and random strangers/spammers to my underlying AT&T number which I never give anyone. Using just the default "Messages" app for that.

The only corruption issue I can think of with another app is if something hangs in sending/receiving and there's some sort of bottleneck. Then stock messages app potentially can't receive/send messages. Sort of like how if you have used a bar code scanner app (and didn't close it), the camera app tells you "camera is not available" because the camera framework is being used by another app.
[LG V30 Guides, News, & Discussion] anubus45:
I am mildly curious if anyone has seen any updated news on T-Mobile's timeline for axing the ability to connect without VoLTE support?

I know I am running on borrowed time, but so far I am still stubbornly, but successfully, running LOS on a US998 with T-Mobile.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Originally they had strongly implied it would be the beginning of this year, but then the pandemic happened. Instead they seemed to have changed to "VoLTE capable" proof based on phone model/IMEI -- not whether you (on LOS) can send/receive VoLTE calls.

So, what's going to happen, much like with former Sprint customers and CDMA, is HSPA will wither away to a bare framework as 5G continues to roll out. Similarly, T-Mobile won't officially turn off CDMA for former Sprint customers for awhile (promise to FCC) but it will be increasingly hard to find, with large pockets of nothing -- especially off the major highways. I predict the same for T-Mobile HSPA. You will increasingly see skeletal HSPA until they announce the final flip switch.

Verizon has admitted they have changed their timeline yet again for their CDMA. Discussed a few posts back. Pandemic has people clutching to their phones and the "Internet of Things" (IoT) with cellular connectivity with home alarm systems, farm crop sensors, etc can't be replaced easily right now. CDMA was used in a lot of that.
[LG V30 Guides, News, & Discussion] |0|:
I had bought one from Amazon, and figured out it was LS998 converted to US998. I did TWRP it to 20b.

I have an AT&T prepaid sim which has been working pretty fine till yesterday. When all of a sudden my cellular data stopped loading any page except att.com(ofcourse!). I do see 4GLTE on the status bar.

The ATT support guy says, my phone is no longer supported pointing me to Feb22 deadline notice.

Can i flash H931 to my original LS998 device and make it work somehow?
[LG V30 Guides, News, & Discussion] waichai:
I have ATT prepaid with v30 US998, flash ATT rom H93120h. It's still working fine. I just received a ATT text "Starting April 12, 2021, we may redirect your call to customer service to help you upgrade your phone.

Will this phone survive or should I look for new phone?
[LG V30 Guides, News, & Discussion] ChazzMatt:
Don't know. Depends on if they are looking at original IMEI or the firmware it has on it right now.
[LG V30 Guides, News, & Discussion] waichai:
Probably won't survive. I just run imei check on cricket wireless site.

Apologies! This LG-US998U LG-US998U is not compatible with the Cricket Network due to network changes. Please visit cricketwireless.com/3Gnetworkshutdown for more details or see your Cricket store rep. If ATT only allow H931, then US998 has no luck. They know what exactly device we are using, not just V30 standard. My international Note 10 plus (N9750) got kicked out on ATT. It will never work again. Now I use it as a wifi device.
[LG V30 Guides, News, & Discussion] ChazzMatt:
I have AT&T postpaid, my wife and my mother both have AT&T Prepaid (service formerly called GoPhone). We've not received any warning messages from AT&T.

You can always buy an AT&T/Cricket V35. It's like an updated V30. Faster processor, 6GM RAM. No notch.
[LG V30 Guides, News, & Discussion] danbest82:
Hmm. Looks like the v35 has Bootloader unlock, root and TWRP also. Not many options after that but I usually use stock ROMs anyway. Especially now with needing the VoLTE of a Verizon ROM. I guess I'd have to switch to AT&T though. Hmm.
[LG V30 Guides, News, & Discussion] ldeveraux:
Why would you need to switch to AT&T? The V35 supports LTE.
[LG V30 Guides, News, & Discussion] danbest82:
The V35 will work in Verizon??? I must do more research!
[LG V30 Guides, News, & Discussion] ldeveraux:
I think so? Gsmarena says it uses lte, but you should totally confirm. I read about it on xda and there might be an issue with twrp.
[LG V30 Guides, News, & Discussion] ChazzMatt:
AT&T has been sending warnings to customers if their phones will need to be replaced by February 2022 when their 3G shuts down.

My wife and my mother both have/had native B&H Photo US Open Market US998 V30 -- not Frankenstiened. They both received the warning messages. Of course it's a nag to prompt new 5G phone sales. :rolleyes:

AT&T refuses to whitelist the US Open Market US998 V30 even though they could. So, I've already given my wife and my mother V35 phones which are whitelisted. Interestingly I have NOT yet received any such message, but I have rooted V30+ with VoLTE flag enabled. Not sure if it works, but it may be the reason I've not received a notification? :unsure:

Here's AT&T's most recent whitelist for post-3G survival. 7-page PDF. See

this link

or attached PDF.

One of the LG V35 phones on the list is NOT AT&T, does NOT have AT&T firmware. Which makes the lack of the Open Market V30 making the list head shaking. The problem is all the LG V-series phones on this list are 64GB, not 128GB or higher. I haven't even looked at any of the G-Series on the list.

• V60 ThinQ (LM-V600AM)

• V40 ThinQ (LM-V405UA)

• V35 (LM-V350ULM) (carrier unlocked phone, much like U.S. Open Market. AT&T Cricket sold these phones.)

• V35 ThinQ (LM-V350AWM) (AT&T branded phone)

• V30 (H931) (AT&T branded phone)

• V20 (H910)

• V10 (H900)
[LG V30 Guides, News, & Discussion] postmortem.:
There's similar AT&T document that lists only unlocked phones.

https://www.att.com/idpassets/images/support/wireless/Service-Capabilities-Unlocked-Devices-ATT-Network.pdf

Yeah, only G series on the list are G7, G8 and G8X. Only V series phone is V35. Strange ... it is least used out of all V series.

Interesting inclusion are Asus ROG phones ( ROG 5 got same quad DAC as V series) and Sony Xperia 1 and 5 mark 2 phones ( 4K display, lots of storage, headphone jack, no notch .. is this what V series should have been? )
[LG V30 Guides, News, & Discussion] ChazzMatt:
Thanks. And that one even lists the services you will get.

For my wife, I gave her the AT&T V35 but it's dealer unlocked AND flashed to different carrier unlocked firmware. My mother's is V35, carrier unlocked by dealer still with AT&T firmware.

I'm looking at the Galaxy S10+.
[LG V30 Guides, News, & Discussion] ldeveraux:
What gives you any indication that the V30 will stop functioning on their network? I understand it hasn't been approved or whatever, and they are trying to upsell you on a device. But why would the phone magically stop functioning on 4G?

And fwiw, my partner just got an S10, but doesn't root/unlock/etc it. Just uses it as a phone. I mean really...
[LG V30 Guides, News, & Discussion] ChazzMatt:
Because we are getting text messages from AT&T saying the phones won't work and the PDF I shared shows only the AT&T branded V30 (H931). So, it's not all V30 that will stop functioning -- just any without H931 IMEI. They whitelisted their own V30.

"Talk and data services won’t work for wireless phones and devices that don’t support at least 4G LTE and HD Voice"

.And to clarify, in spite of the wording above, stop functioning as phone. 4G LTE data will probably still work, unless AT&T shuts it off to get your attention. But without VoLTE you will not be able to temporarily drop down to 3G HSPA to take phone calls. And the PDF I shared shows all the current phones for which AT&T is whitelisting VoLTE. The are whitelisting the carrier unlocked V35 (LM-V350ULM) -- as well as their own branded V35 -- but not the carrier unlocked V30 (US998).

Here, go read this AND it has the PDF again.

[LG V30 Guides, News, & Discussion] ldeveraux:
I'm not trying to get too deep into this because frankly it doesn't apply to me. I have a good carrier. But to clarify, you're saying AT&T will blacklist certain IMEI's or whitelist the ones they want? Will they literally make a list of every H931 IMEI and only allow those particular V30s to access the network? I didn't know they could get a list of every H931 ever made and not run into major problems with that.
[LG V30 Guides, News, & Discussion] ChazzMatt:
AT&T already has a list of all AT&T H931 IMEI. It's their branded phone. They paid LG to manufacture the phone, so they know all the H931 in existence. All LG H931 went through AT&T at some point. If not sold directly to consumers, then overstock sold to wholesalers.

Just like Verizon knows their phones, and T-Mobile knows their phones. For the carrier unlocked LG V35, which Cricket sold, AT&T knows the IMEI range.

AT&T gets to decide what phones get VoLTE & Wi-Fi calling on their network. Please

go look at the PDF

. Updated as of May 14, 2021. They ARE allowing some "carrier unlocked" phones to have VoLTE (even as old as Pixel 2!) -- but not the U.S. Open Market US998. If you don't have VoLTE privileges then you won't get AT&T phone calls after February 2022. Some carrier unlocked phones will get VoLTE and Wi-Fi calling, but you need at least VoLTE.

T-Mobile and Verizon will be doing the same thing to different extent. When Verizon shuts off 3G CDMA and T-Mobile finally shuts off Sprint's CDMA for former Sprint customers, they will limit the phones which can be used on their networks.

Even though AT&T isn't shutting down 3G HSPA until February, AT&T started warning customers with text messages back in March. They shut down 2G couple years ago and now it's 3G. I replaced my mom's V30 with AT&T V35. I gave my wife AT&T V35 flashed to carrier unlocked firmware, but she's still using her V30 for now as I haven't transferred all data yet.

This is part of Page 2 of 7 pages of phones which will be allowed to have VoLTE.
[LG V30 Guides, News, & Discussion] ChazzMatt:
duplicate.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Who is your carrier? If an MVNO, who is the underlying carrier? To my knowledge, all three major U.S. carriers (AT&T, T-Mobile, Verizon) are implementing 3G shutdown. Each of the three decide what phones (besides their own branded phones) get VoLTE privileges and what don't. T-Mobile for instance has been very good about giving that to the US998 V30.

There are some regional standalone carriers who are still keeping 3G for now. But if you have one of those and you go roaming on one of the major U.S. carriers, you won't get phone calls if the underlying carrier is AT&T and you have US998.

All MVNOs using the major U.S. carriers will also be affected. While they may provide their own data, they don't provide phone service, the carriers do.

As we get closer to February 2022, it's entirely possible the AT&T PDF list may change to include some more.
[LG V30 Guides, News, & Discussion] ldeveraux:
been on verizon for 15 years so I'm frankensteined to a VS99630c. I have HD calling and VOWIFI both working gangbusters. I don't see how the 3G shutdown will affect me, as I don't see vz pulling that crap. I'm sure I'll eat crow on that statement, but I haven't found a suitable replacement yet and I don't care enough to deal with it atm. I wish there was a better solution for a new device that meets our needs, but I don't think we're there yet.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Yes, if your HD calling/Vo-WiFi is working on Verizon, then it will continue to work (my opinion). My sister still has Frankensteined US998 V30+ on Verizon (as did my brother in law but he recently upgraded to newer Galaxy phone, Verizon branded). They got a helpful Verizon customer service rep to activate VoLTE, etc in their accounts for the Frankensteined LS998 to US998 phones. It's still running US998 firmware, not even VS996. The rep said "Verizon says your phones won't work on Verizon but they will. Don't tell anyone I did this for you."

Yes, AT&T is pulling crap. For some reason they are not exempting 2017 carrier unlocked US998 but are exempting 2018 carrier unlocked V35 -- probably because AT&T-owned Cricket sold the carrier unlocked V35 but not the Open Market US998 V30/V30+/V30S.
[LG V30 Guides, News, & Discussion] ChazzMatt:
Here's the message I received today from AT&T. Both my wife and my mother had already received these warnings, so I knew about them. But I had not personally received them on my phone -- native Open Market US998 V30+ bought from B&H Photo.
