Unlocking LTE bands on a US Cellular LM-V405UA that is now on Google Fi? - LG V40 Questions & Answers

TL;DR: USCC -> AT&T -> Google Fi -- Any way to get 4G/LTE on these carriers?
Hey all,
I haven't been very involved in the rooting/flashing/whatever scene since the Gingerbread-KitKat days, so my apologies for what might be a noob question, or if it even is the right question to ask.
A bit over a year ago, I switched from US Cellular to AT&T and brought my V40 with me. Despite some IMEI issues (was only 14 digits instead of 15, which messed with some online forms), I eventually managed to get it transferred. However, there was one big issue: I was only getting 3G/HSPA+ service. I imagine this would've been a deal breaker for most, but since I only really use my phone data for music streaming and Google Maps when I'm driving, it wasn't that big of a deal for me.
Then, recently, I switched to Google Fi to save money. I knew that the V40 didn't support the fancy carrier-switching stuff, but I didn't care as long as I had some sort of service. The same problem still persists, however: I only have 3G/HSPA+ service.
When I briefly looked into this last year, I remember seeing something about flashing some firmware that'd unlock the non-USCC LTE bands, but I'm not sure if this was valid (could be misremembering). Would flashing some sort of firmware on my phone allow me to have 4G again, and if so, what would I flash? The generic US unlocked firmware?
Also, not sure if this matters, but GSMArena and LG's own website both seem to state that the US Cellular's V40 model is the LM-V405UA0, but my model number according to Settings is LM-V405UA (no zero at the end). My phone worked fine on US Cellular, so I'm not sure what difference there is between the two models, if any.
edit:
Messing around with my phone settings, I was actually able to force a 4G LTE signal from T-Mobile (Google Fi's primary network iirc) under Settings > Network & internet > Mobile networks > System select and flipping the Network mode option between "Global" and "LTE/GSM/UMTS". Going from the latter to the former will switch me to 4G/LTE from 3G/HSPA+, but going in the opposite direction keeps me on 4G. To revert, I have to go further into the GSM/UMTS settings and select "UMTS/HSPA/HSPA+ only" in the Network submode option.
Both the 3G and 4G options had about the same (slow) network speed of 2mbps down, and according to Signal Spy, the LTE was probably using band 4 (it had a question mark beside it, implying it wasn't very certain). I don't know if it's a band issue or a location issue, but since I'm on WiFi most of the time nowadays, I'm not that pressed about it... maybe I'll back things up and flash the US Unlocked firmware as a weekend project sometime.

This happened to me a few months ago. The phone is definitely capable and you will get LTE signals on the $60/month GoPhone plan.
1. First of all, call GoPhone customer support (611 from the phone) and confirm that they have your HTC One whitelisted for LTE. They're going to double check with you your phone's IMEI number (they can already see it, but will ask you for it anyway), and then confirmed that the phone is allowed to get LTE signals. They're also going to double check your APN setting and provide you with the appropriate entries for AT&T.
2. Reboot and see if you now get LTE signals. If you still don't get it, check whether your mobile network settings is set to GSM/WCDMA/LTE Auto instead of GSM/WCDMA Auto or WCDMA Preferred (or maybe something else). If you don't see any LTE option, dial *#*#4636#*#* from your dialer, and in the first drop down box choose 'GSM/WCDMA/LTE Auto' or anything with LTE just to make sure you can catch LTE signals at all. If you were able to find and switch to the setting you want, exit out, and go back to that menu, double checking if the setting sticks. If it does, reboot and try again.
3. Most people will get LTE signals after #1 above, while some were only able to get it after #2. However if you are unlucky like me, the LTE setting does not show up in mobile network and no matter what I do in the hidden menu, the setting won't stick (it's stuck on GSM/WCDMA Auto). I actually tried flashing a different radio at this point (a newer AT&T radio), but still... no LTE for me. What solved this finally for me is that I flashed a custom ROM (in my case it was ARHD 12.2). This enabled me to choose GSM/WCDMA/LTE Auto under mobile network settings, and after that I was able to get LTE. It was great! :good:
Hopefully that helps. Good luck!

Issue with At&t unlocked Moto X 2014. on t-mobile

So i am having issue. I bought a Moto X 2014 and it is clean in terms of imei. Both t-mobile says its clean and at&t says its clean. It is a AT&T variant XT1097 and like i said it is clean in terms of imei. weirdly enough T-mobile wont be picked up on the service, but AT&T will? it basically says
No Service
selected network (T-mobile) unavailable
and when i do try to select a network it says
"cant connect to network right try again later"
has anyone else have this issue with the AT&T moto trying to use it on at&t? and found a solution? if there is any solution ill take it i need all the help i can get lol
i tried reseting it, factory reseting, airplane mode, etc literally almost everything else.
Sorry.....I have similar issue..Did you find the solution? If yes could you share the info for it.

Add the T-Mobile APN.
it's discussed on the ATT thread, basically it's an issue with the lollipop radio used on our update, "fix" is here: http://forum.xda-developers.com/moto-x-2014/general/att-xt1097-lollipop-discussion-t2951294/page36
Add the APN (as mentioned above)
Download the 4G/LTE switcher app
select WCDMA preferred as network, only HSDPA speeds but it's better than no service ^_^
I had this similar issue and it was driving me absolutely insane, the connection would be weak then it would just disconnect me altogether and then zero service. Most of the time if I were to get a call the radio would switch to HSPAP like normal then after the call it would fail to switch back to LTE then it would just completely drop connection. This is on an unlocked AT&T XT1097 running on the unlimited MetroPCS (T-Mobile) mind you.
Since February 2015 I've been dealing with this bug by using LTE switch to get by, but this got so tedious and it just irked me that I had to go thru all this crap because of poor development. This is a pretty huge bug that should've never been there to begin with. Seriously, how dare you mess with my service Google?
Anyways what I did to fix this completely was just purchase MoFoRoot for $20 (fully worth BTW) and flash the 4.4.4 AT&T modem and now I have zero issues. I used to not connect to the network on a reboot but since flashing the modem I am now able to connect and stay connected without any hassle. The connection is now solid and I can't be happier with this phone. Currently on stock 5.0.2 non-rooted with 4.4.4 modem and zero problems, now I don't need to get another phone.
Using the fast.metropcs.com APN as the T-Mobile APN doesn't allow me to connect. I have solid LTE and HSPA/HSPAP service with it and can't be happier... I take that back, I'd be happier with better indoor coverage.
Thank you makers of MoFoRoot for your lifesaver app, I am happy to have supported your fine work.

VoLTE on At&t

So I spent an extensive amount of time about this whole VoLTE situation with this phone with both At&t and ASUS. My question is how do you know if you are actually utilizing the VoLTE connection?
I am able to make clear voice calls while browsing the internet or downloading an application. My speeds vary anywhere between 60 and 100 Mbps with no connectivity issues. The phone has no indicator of LTE connection but is constantly 4g++. Asus and at&t both stated that is the LTE connection. So I went into the phone settings via the image in this and it shows the VoLTE setting not toggled.
So the next question is, what indicator is there that this connection is NOT VoLTE other than this toggle? The speeds appear faster than Hspa+ but nobody I spoke to had the technological knowledge to be able to explain this. Also what speeds down and up is everyone else receiving?
From what I have read, this phone doesnt support VoLTE. And what worries me is that all the carriers are transitioning to VoLTE starting in 2020. Some are saying phone calls will no longer be possible on this phone. Which confuses me as it just released.
You can tell by making a voice call and seeing if the phone stays on 4G++ or drops to 2G/3G. I am 99% sure we will not get VoLTE on this phone. TMobile rep suggested tweeting TMobile on Twitter as the marketing team there might help, but I just don't care anymore. I'll stick with my pixel 2 xl for now.
Is ANOTHER thread on this necessary? Wtf? No volte. Not now, not ever. Get your money back. Asus are idiots for releasing this phone in us with no volte. 2020, no phone calls. Enjoy!

I know VoLTE is 100% possible on this phone, however not in the USA. It has something to do with the USA companies and At&t told me VoLTE is definitely a possibility as well as WiFi calling in the future but that has to be certified by the US companies. This phone supposedly works with WiFi calling as well as VoLTE in the European market as they don't have the same issues with the companies controlling the way it operates. I am moving to Norway on the 23rd but honestly the connection has been fantastic and I do like the phone quite a bit. During my phone calls I remained at 4g+ or ++ while surfing the web or watching Netflix with no issues during the call or the film itself.
I have messed around with it to see if there was anything that seemed off about it but so far it has worked just as well as My note 10+. Also the phone is operating on 4g so saying that it can't be used is silly. The 4g band will be around for quite some time while some companies like Verizon are removing 3g as it operates on the cdma versus gsm. At&t will continue 3g operations until 2022 and 4g will take years to completely phase out from 5g and by then another phone will replace the ROG 2.
I will however annotate how this phone operates on the European networks once I arrive. As per my previous post I can obtain 40mbps up to 100mbps which is definitely 4g speeds. 3g can not obtain those types of speeds. The bands available are key to the operating network for sure though. I think at&t seems to offer the best fit here in the USA.

I am currently using this phone with AT&T. So should I be good for calls through 2020 and 2021? Reason I ask is because I literally just got it a week ago, and then read this news about the whole VoLTE thing and was just devastated thinking I have to now find a way to sell it and find a new phone.
Also, since I got the phone, I am only ever on H+ for the signal. I thought it was LTE capable? I came over from Verizon, so the H+ was something new to me. I know I am in a LTE area. Do I need to do something to activate it?

Was this a ported number? When I went from Verizon to at&t there was an issue when I ported the same number back to at&t. They were able to get it resolved by calling Verizon having them refresh the port and then re initiating the LTE from their end. And that was with my Samsung. I did speak to at&t again today about the LTE and they may have to make sure your Sim is "LTE" and also making sure they unlock it on their end. Supposedly the LTE and volte have to be activated from them. Also ensure you have the appropriate APN setting as sometimes with unlocked phones those setting do not carry over.
And the phone should be working fine until a minimum of 2022 even with 3g or H

I did bring the number over from Verizon. I may have to go in to AT&T to resolve that from what you're saying then.
Dealing with the APN setting, I am good with tech, but this part has me a tad confused. What should I be looking for on the phone? I see under APN, it says AT&T is selected. There are other options like tracfone, but I assume its fine then if it has AT&T selected?

And yes something about how Verizon and at&t handle it some things can get "hung up" in the system

I tried those APN settings and it seems to not work. The signal bar still shows a signal, but there is no longer a H or H+ sign. Hmmm

That's interesting, but I would recommend going to at&t and confirming that LTE is good to go on your phone. They can also verify nothing is stuck in the system and your appropriate APN settings

Question Android 12 Breaks 5G NSA?

Hi, I updated to Android 12 when it was released, and it seems to have broken 5G NSA support on T-Mobile. With non-standalone in my area, I'm able to connect to midband 5G and get excellent data speeds. After the Android 12 update, it seems to prioritize standalone (SA) lowband 5G, which is often even slower than LTE, and I have not once seen it connect to NR NSA. I never encountered this on Android 11, but don't want to reflash my phone just to troubleshoot. I'm wondering if anyone else has encountered this issue. Thanks!
what app are you using to get the connection info? i have yet to find a network tools app that handles dual sim phones well. a few apps state android os itself dropped 2 sim support after android 9.

I'm just going into Settings -> About Phone -> SIM Status. It tells me the type of connection for voice and data. If I were on midband, it would show LTE for Voice and NR NSA for data. But it's showing NR SA for both, indicating my phone is on lowband.

ok. i just got a straight talk t-mobile sim activated this morning and i show LTE for voice and NR NSA for data network type. i've done a few speedtests and it's been between 130-150Mb down with 30 Mb up. however, google fi which is same t-mobile tower gets over 200Mb down /30Mb up. so it just appears to me that t-mobile gives a sweeter deal to Fi than to straight talk. but that's just one morning and a couple tests.

Hmm, I'm on a normal T-Mobile plan, but I'm not sure if that would make a difference. Are you on Android 12?
This issue only showed up for me the day I updated my phone. I don't think I dropped it or anything, so I doubt it's something physically wrong with it. But I don't want to unlock the bootloader, wipe my phone, and roll back to Android 11 just for troubleshooting.
Figured out a solution. I stuck in my mom's T-Mobile SIM, which is much older and doesn't support standalone 5G, and it connected to NSA. So it's some software thing where they're heavily prioritizing SA 5G over NSA, even when NSA is available and SA is garbage.

Yes, android 12. As well as a new sim. There was some mention by T-Mobile of having a new sim for the 5G. I have no idea if s new one is required, just that they said it in the materials they sent me that 5G would work best.
I have T-Mobile and am getting great service with 5G where I am. I have just recently got it connected though, and I was already on Android 12 when I had it connected for service. Not sure if that matters though?
I use Mint on T-Mobile towers. I just upgraded to Android 12 OTA, and with the adaptive connectivity setting enabled I see LTE as the mobile voice and the data fluctuates between IWLAN and NR NSA. I have wifi-calling enabled, with mobile network preferred. I didn't pay attention to this status screen in the past, so cannot say if anything changed really...

Enhanced 4G LTE Mode "in" Mobile Network setting, and CDMA-1xRTT instead of LTE in Mobile voice network type in SIM Status

So, my wife and I have had two of these phones, Moto G6 phones, for about 4 years. And in that time, they've worked great using the Straighttalk (verizon) network. Recently though I switched to the Mint network because they said my phone was compatible ... even though it looked to me that they were a GSM. They also indicated I was in a great 4G coverage area. But, Coverage was terrible. I couldn't place calls in MANY of the neighborhood locations I used to be able to with straighttalk. And, other people said they would call me and they would never hear my phone start to ring. Nor did mine ever show I missed their calls. It was difficult but I finally got my phone switched back to straighttalk. But ever since then I have found that I can't place a call or text out in places I used to be able to. This has been going on for a few months.
Recently I was comparing my phone screens to my wife's and found two items that are different, when I think they should be the same.
In mobile network settings my phone does NOT show Enhanced 4G LTE Mode whereas my wife's does. It's simply not on my screen of information.
Also, in my SIM Status, my phone indicates the Mobile voice network type is "CDMA-1xRTT" whereas my wife's simply says LTE.
Are either of these two settings responsible for my not getting good calling service, and if so, is there a way to change my settings to hers? There is nothing I can see anywhere that I can change in all my settings that seems to effect this.
Do you think doing a factory reset my get me back to Enhanced 4G LTE Mode? I vaguely recall that the Mint sim was making some kind of changes to my phone.
Any other ideas?
Mint is obviously a GSM network since it's based on T-Mobile, and it works quite well on my G6, unlocked and bought from Motorola directly.
If you have a Verizon phone (which that CDMA-whatever talk sounds like), then you're going to need to stick to Verizon most likely. I have no idea if there is a Verizon specific G6, but I bet there is. RedPocket has Verizon options also if you are looking at cheap MVNOs.
And of course, using an MVNO you need to make sure your APN is right.
