Hello all,
I've looked everywhere on the internet attempting to find an OTA file to flash to get me to this version without S-OFF and changing to Developer Version. Does anyone have the file for this OTA? I do not have ATT service so i'm unable to do a software update.
Thank you.

I only need it cause AT&T killed 3G and now you need to use VoLTE and VoLTE registration doesn't work on LineageOS and many custom roms, so I need to go back to stock just to for a moment to get VoLTE to work and then I can go back to Android 11 on LineageOS.
Many Thanks.

yeah i am pissed with ATT they blacklisted my HTC U11 because of the VoLTE crap. yet they whitelisted the M9 and M8 phones. when the U11 has VoLTE. they just wouldn't add it to the whitelist of phones. now i am stuck on some garbage pixel 5a and buggy AOSP roms that never work right. the sad part is this pixel is slower than my U11.
no idea what version this is but it is for the att m9

I have two U11's and one works fine on AT&T with VoLTE and the other doesn't. I also have two M9's where one works fine with AT&T on VoLTE but the other doesn't . The phones that don't work LTE does work, and it says that VoLTE is provisioned the only issue is IMS registration isn't getting registered so VoLTE calls won't work and this is on AT&T side.
Now here's a funny bit, I also have a U11 Life and that phone works fine on AT&T and it's not even on the whitelist. So, it makes me wonder how they are determining which phones are "compatible" or not.
The U11 and M9 that do not work on VoLTE but LTE works fine and they show as provisioned are both quad band phones originally sold by CDMA carriers but there is no legit reason they cannot be used on GSM networks as they are multiband phones capable of using any service.
So, I was going to flash AT&T stuff to my Verizon M9 and see if it works like my AT&T M9 and AT&T allows IMS registration to occur. From what I understand the IMS registration happens between the Qualcom chip and the carrier, and your version of Android won't interfere with it afterwards, At&T seems to be pickey about the IMS implementation. Meaning once IMS is registered you can swap back to whatever flavor of Android you were using before like LineageOS or whatever.

i got my htc u11 direct from htc the unlocked version. i was at ATT back in august 2021 trying to get a new sim card for it and a new sim card for my pixel 5a because you need a 5g sim card to get 5g to work. i just had them activate the sim cards. when i got home to put them into the phones. the new U11 sim card was blacklisted so i couldn't get it to work at all and i had to go back to ATT to get the sim card unlocked . they told me that i could not i could not get a new sim or change sims for it, because the phone was set for termination in feb 2022.
that is odd your U11 does work. maybe i will try it again with the stock rom and see what happens at worse case i have to get the sim card unlocked again. i currently use the sim in a zbt wg1608 lte router. so when i travel i have unlimited LTE data for my laptop and i don't have to pay the hotels outrageous prices for 24hrs of internet.
Hello everyone
I have an LG v30+ running stock android 9 with the global v31a rom.
Today I moved to a new carrier, and after installing new sim, the cellular internet works just fine, but voice calls and sms are not working.
I get the "phone not allowed for voice" message and on the taskbar shown on a "MM" icon.
At first I also received an error windows I attached here.
Moving the new sim to another newer xiaomi phone - everything works fine including calls and sms.
Customer service couldn't fix them from their said claiming it's an issue with phone configurations.
Any idea on how to fix this?
Thanks
I just tested another company's sim card and everything works fine.
So it must be some support from the new carrier
Any idea what can be done before I chose another carrier?
What is the model number (Settings -> General -> About phone -> Hardware info)?
Please share a screendump of your Network status screen (Settings -> General -> About phone -> Network). You can blank out the IP address.
Also, please share screendump of the Testing menu Phone information screen (dial *#*#4636#*#* -> Phone information). Scroll it up 3 lines lines so you don't share IMEI, Phone number, IMSI, but so that we can see all the Provisioned lines.
First thing I would try is a Network settings reset (Settings -> General -> Restart & reset -> Network settings reset) then restart the phone.
It is possible that your carrier only provides voice over VoLTE (and SMS over IMS, which is part of the same feature set). That only works if the phone knows the correct settings for your carrier. That would explain why it works with the newer Xiaomi phone. You can check if you have VoLTE settings in the menu (Settings -> Network menu -> Call). Even if the phone does NOT know your carrier, you may be able to configure it through the Hidden menu (depending on your model number). But it is VERY complicated, and you need detailed information from the carrier about the settings to enter.
Or it could be something else entirely.
On a different note, this thread definitely should have been in the Questions section, not in the Guides section.

Not sure why you are calling 31a "global". It's merely the European H930 31a Pie. I've seen a couple of other people use that term and not sure why... It's not "global" in any way than any other KDZ. (EDIT: I see your screenshot where it says global, which is very strange. Is that some setting? That's just weird.)
Unless you actually have an H930 phone, using the H930 KDZ will not give you the H930 bands or anything. You are still using the LTE/HSPA bands that are on your variant. Some people use H930 firmware on H930D/H930DS for different language options and vice versa. So, "global" is quite an exaggeration. Canada H933 has more LTE bands than any of the V30 variants, so it's really the "global" if any are. (But you can't convert to Canada H933 unless you have a compatible North American variant.)
What variant do you have and what country do you live in?
Ahh, so a European H930. Which country are you in, and who is the carrier?

I don't know where you live and what variant you actually have, but you are using EU H930 31a KDZ.
For instance, if you are in India and using Jio carrier, you need India H930DS KDZ as Jio is VoLTE only. But H930 31a doesn't have Jio's VoLTE settings... Using "another carrier" which allows legacy HSPA during phone calles would then be why it works on the other carrier but not Jio. To fix that you would need to flash India region H930DS firmware.
I am not saying you live in India or using Jio -- you didn't give us any information about that. I am just giving a real life example of why your phone would work on one carrier but not another.
Also, some carriers make you register your phone. If you just stick the same SIM card in you had from previous phone, it sees it's a different phone and will throw up an error message like that until you call them or go into store and tell them what "new" phone you are using. The "other carrier" may not be such a control freak.

Since he says he has V30+, I know he doesn't have native H930 phone. There are no H930 V30+. The V30+ are H930G and H930DS and neither on them have firmware numbered "31a".

I see posts from you back in November and you have been on 31a for awhile...
https://forum.xda-developers.com/showpost.php?p=81065243&postcount=852
So, any issues have to be with this new carrier as you have had phone calls on 31a for most of a year now.
Sorry, double post
Thanks everyone for the replies.
@TheDannemand
Some more information about my device:
Country: Israel
Carrier: We4G
Hardware version: LH-H930G.
Looking up using my IMEI number on lg-roms website gives this model: LG V30 Plus TD-LTE
I shared the network menu testing menu you mentioned.
I DO NOT see any VOLTE setting in the Call menu.
I already tried network settings reset.
@ChazzMatt
I have the H930G version. Actually I always follow your guides in that thread to upgrade the version, and I've been on this stock firmware for a year. So it must be something related to the carrier settings I think.
I actually didn't use my country's specific KDZ file as it was released a bit late. I used the european version if I remember well.
Should I flash the local one? According to lg-firmwares and lg-roms website it's this one:
Code:
https://lg-firmwares.com/downloads-file/21127/H930G30a_00_OPEN_IL_OP_0903
Will it have an impact on call services and bands?
Any chance it is really a carrier using VoLTE for calls? I tried asking all kind of questions but didn't get any smart answer from the tech support team.
Also, what do you mean by registering the phone? I never heard about this.
Thanks again!

For some reason I cannot see your attachments. What I wanted to see was (1) whether you have an LTE connection and (2) whether the phone sees VoLTE as provisioned. In truth, I only need the Phone info screen (from the Testing menu) to see that.
I think it is quite plausible that your carrier requires VoLTE to make calls and that your ROM doesn't support it because it doesn't know your carrier. A ROM for your region probably DOES know your carrier (if they are well established). But it's also possible that it doesn't (if they're newer or changed their VoLTE parameters in recent years).
This was my first thought when I read your post and saw that you were on 4G (which should be LTE, although in USA carrier marketing departments have diluted the term to also cover old 3.5G). And I see that it is ChazzMatt's thought too, with the example from Jio India.
I googled We4G to get a clue if they're VoLTE only, but all the links were in Hebrew
Carriers who don't require VoLTE drop the connection to 3G in order to make calls. This works on every phone that supports LTE because it doesn't require knowledge about your carrier.
However VoLTE relies entirely on VoIP and requires an elaborate login to carrier servers, with security and handshaking to prevent illicit use of their network. And the parameters for that are carrier specific. Each phone has a so-called "buffet" of carrier configs known to that ROM. That's why it matters to use a ROM that knows your carrier.
Thanks for the detailed reply.
I think I'll try the local ROM I mentioned. I just want to be sure it doesn't make a clean wipe if I flash Kdz with LG UP. is that so?

Thank you. I see your attachments now.
So you do indeed have LTE connection for your mobile data. But the phone doesn't even pick up VoLTE provisioning -- which is the first and most basic step in supporting VoLTE.
I would definitely try the regional ROM, but you should flash with Refurbish or Partition DL -- which means losing data. Sorry.
In fact, since you're doing a Frankenstein, I would flash back to Nougat first using Partition DL (to update the partition table), perform a Master Reset (it may bootloop until you do), then flash up to Pie. Wait for @ChazzMatt to confirm those steps.
Good luck to you

I really hope I can flash it without losing data. I prefer not to back up all data.
That's what I also did in the previous rom upgrades.
Would that be possible?

I don't see any way to do this safely without losing data. Sorry.
You could skip that carrier and go with one that doesn't require VoLTE (i.e. one which supports the old dropping to 3G for calls). But you won't have the benefits of VoLTE and WiFi Calling. And you may be in the same situation later if that carrier decides to close down their 3G network and go VoLTE only.

Try enabling 'VoLTE Provisioned' on that screen then restarting your phone.
Is there an 'Advanced Calling' menu in Settings?
Two things that might help:
1) Before taking the plunge, put the SIM in your Xiaomi phone and see if you can make a call WITHOUT using VoLTE: One way is if Settings menus allow disabling VoLTE. If no Settings menus, try the same Testing info - Phone info screen and see if VoLTE is provisioned there. I assume it is. But if VoLTE is ALSO not provisioned on the Xiaomi, that means the problem isn't lack of VoLTE on the V30.
2) Just backup the phone using LG Backup, either through Settings -> General menu -> Backup (then transfer file to PC or flash drive) or using LG Bridge. It backs up all app data and most phone settings (though not all). And I was able to use it across different ROM versions and even different ROMs (between H932 and US998).

Yeah, as long as the phone doesn't see it as provisioned, we can forgot about menus and settings.

The screenshot doesn't include the VoLTE line. But if VoLTE is ALSO not provisioned on the Xiaomi that means the problem if elsewhere, not lack of VoLTE on the V30. So hold off on that Frankenstein for a bit.

So, Oxygen OS 11 didn't support 5G on my carrier out of the box. However, I managed to get it to work by replacing the carrier_policy.xml file with this tutorial:
OnePlus Community
Introducing our new OnePlus Community experience, with a completely revamped structure, built from the ground-up.
forums.oneplus.com
It got wiped with every system update, but it's never been hard to reenable. However, with Oxygen OS 12, the procedure doesn't work at all because the Engineering Mode APK refuses to install. So, I'm stuck on 4G. Is there any other way to get to said file and replace it? Preferably without rooting the phone. Thanks in advance.
For some people (me included) 5G is working, but on 2nd SIM slot only.

Mine's not working at all. Two different carriers, the option shows up in the menu, but enabling it does nothing. It's exactly what happened in Oxygen OS 11 before I replaced the carrier policy file, hence why I'm specifically asking for a way to reach it in Oxygen OS 12.

Hello, Volte used to work well on my op9 pro recently updated to A12, I tied switching my sim card from sim 1 to sim 2 as I read some users were able to connect to 5g that way, well, it didn't work and when I switched my sim back, volte stopped working, tried restarting the phone a couple of times, no luck. Any ideas ?
Also, even before switching to A11 5g never worked and still doesn't work on my 9Pro in the UAE, tried all possible solutions and it still doesn't work, any possible solutions?
Can you try to reset your APNs and/or the whole networking? (Beware: by resetting the network you'll loose your saved WiFi configurations.)

I was getting the same issue, but flashing a different variant of your current c.44 should do the trick.
Ex: I have a LE2127 (TMO), I converted with a11 to use LE2123(EU) software updates. When android 12 hit my phone wouldn't give me data on the 2123 update, so I had to download the LE2125(global/NA) update and flash using the the system update app that was so generously given in the following post:
Post in thread '[TMO] 9 PRO MODEM RETENTION' https://forum.xda-developers.com/t/tmo-9-pro-modem-retention.4292445/post-86328243
I don't know what software or model your phone is now, so I am NOT suggesting you switch if you are not already on 2123 or 2125. Those two are interchangeable without problem so it should be fine
The question is what is CCT_US so I can get the correct version for this phone? Or the best way to flash to OPEN_US. I have G820QM30c_00_NAO_US_OP_0103.kdz downloaded & the phone is a G820QM with 30c already installed. Trying to get WiFi calling enabled.
OK--I've found more info...The phone is a LMG820QM5 from Xfinity Mobile. LG-Firmwares only lists 30b as the latest version--the phone has 30c....so it looks like cross-flashing it would be the ?best? option?

What carrier are you using / plan to use? The device is unlocked from xfinity?
If you use a carrier like Mint mobile, which I have, yes, wifi calling can be enabled (you would do that on your mint mobile account), with the us Open kdz. The problem is that getting things like vowifi and volte to work, it's a combination of both the carrier and the rom, not just one or the other.
cheers
Device is unlocked--bought it from eBay. Going to use it on the ATT network (Consumer Cellular) The phone has been enabled through CC--I just didn't see the option in settings, so I started to check on what the phone was setup with. Took some tracking to get to the Xfinity mobile conclusion--it threw me a bit that LGfirmware does not list the version that the phone has. Have D/Ld the firmware & plan to start the crossflash today.
Thank You--I used your tutorial & got the firmware changed. I'm out in a rural area & need to goto town to get the phone finished....SO, I'll find out in the next couple of days if this worked...the phone boots & acts normally.
