I'm gonna make a post here since NOTHING seems to be working. I'm a T-Mobile customer. Yesterday, I purchased a great condition nexus 6P from someone because my LG G5 is cracked and I was getting tired of it anyway so I opted to just buy a nexus instead of using my insurance on that phone. Everything is all good except for one major issue. VOLTE and WiFi calling just refuse to work with my sim in the Nexus.
I've called T-Mobile twice. I've factory reset from back up and reset settings twice. I've hard reset from stock recovery once. I've wiped network settings and restored default apns. I've manually changed the apns from what I see on Google, reddit and here. I've copied my apns from my LG G5 where VOLTE and wifi calling work perfectly fine. I've cleared cache. I've cleared the cache of the project fi and hangouts apps just in case there's something left over from the previous owner. I've gone into the *#*#4636 menu and tried a bunch of different stuff several times but no matter what I absolutely can not get wifi calling or VOLTE to work with TMobile on my nexus 6P. LTE it's self works perfectly fine for data.
Yes, all settings for wifi calling and enhanced LTE calling and VOLTE are turned on lol. I've tried the trick where you toggle wifi preferred on and off and restart the phone. Nothing happens. I don't even get a wifi calling reg error. It never shows as active in the data toggle in the quick settings are nor the status bar or dialer. It just isn't active. Same for VOLTE. I AM getting band 12. I can see it in the LTE discovery app. VOLTE just isn't working though. Whenever I make a call I can see LTE switching off and it switches to HSPA therefore making calls really difficult in my shoddy signal area at my house which is why I really need it to work.
I'm fairly certain I can root and install a ROM which will fix these problems but I don't own a PC. . I thought MAYBE the previous owner had previously had the phone rooted and tinkered with something somewhere that may have messed something up but that doesn't appear to be the case. Bootloader is locked and recovery is stock.
Can anybody help and tell me what in the world is going on here? I don't want to have to sell this nexus and revert back to my cracked screen G5. I would just switch carriers but I still owe money on the G5 so I was just gonna ride it out til I payed it off.
O and one last thing, after scowling google and forums for hours on end yesterday and today I did see one post mentioning something about this stuff being related to IMS provisioning and settings which are tied to a phones IMEI on T-Mobile and not the sim card and how that person simply called T-Mobile and got a hold of wifi calling technical support who was clueless but created a ticket for him and within 72 hours the issue was resolved. OK well I did the same exact thing and they refuse to create a ticket for me because it's not a T-Mobile phone and because according to them they are not allowed to create a ticket because wifi calling works fine in my G5 and therefore it's the phone and not them or their network lol. What a crock. I'm willing to bet if I put the sim in another unlocked phone with 7.1.1 and wifi calling fully available that it isn't going to work either. There's some sort of communication error going on between the sim being in this phone and their network it appears.
Check these screenshots out. T-Mobile is clueless

I can only suggest;
1) Find a PC and re-flash the latest factory images from Google. Both "fastboot flashing unlock" and "fastboot flashing lock" will wipe all data, so backup first. Also confirm it fully boots correctly after flashing before you re-lock the bootloader.
2) Get a new 3-in-1 SIMM from T-Mobile. You can use their web site to switch cards and give it 24 hours to be fully provisioned.
3) Confirm your E911 address is correct on T-Mobile's site and wait 24 hours after any changes for Wi-Fi calling to actually start working.
I HAVE THE SAME EXACT PROBLEM AS YOU POSTED!!! GONE THRU THE SAME PAIN. LOL I'll attempt the ticket thing to see if I get anywhere. Did you ever get it resolved?
EDIT:
My theory is that since the phone was used in Project FI, they specifically turn off this feature in the back end for the specific phones, by Imei or something since project FI uses T-Mobile as well.
EDIT 2:
they wont' create a ticket for me either. I guess I will just have to ride it out.
EDIT 3: I FIXED IT!! NEXUS 6P VOLTE AND WI-FI CALLING FIX T-MOBILE
I flashed back to android 6.0 Build#: MMB29N (I used the Nexus ToolKit 2.1.9: google it. BTW, your phone will be wiped, so backup first) VOLTE just started working with this version of android 6.0. Then I upgraded using the OTAs and now i'm on 7.1.1 build#: N4F260 with VOLTE and Wifi calling working as it should! I hope this helps someone out there!
For what it's worth, reverting to the build you mentioned fixed it for me on my two Nexus phones coming from Project Fi to T-Mobile as well! Thanks for the help!
You only need to install the radio from build MMB29N. I did this by downloading the build from the android website. Extract the radio from the zip and install it (I used nexus root toolkit but you can also just use flashboot if you wanted). This means you don't even need to revert your image and lose your data.

wish I had seen this sooner. cheers!
Had the exact same issue and this fix worked for me. Wasted a couple of hours with T-mobile (they were actually very helpful and debugged everything on their end to confirm the provisioning was good) and then 2+ hours with Google support. Actually had already filed for a device replacement which I canceled after finding this post.
I'm so glad I found this thread - my VoLTE and WiFi calling has not been working on T-Mobile and I'm anxious to give this a try. Numerous phone calls and support tickets with T-Mobile haven't resolved the issue. I don't know much other than how to follow detailed directions. My phone isn't rooted and bootloader is locked. I'm on Android version 7.1.2. Is there a way for me to install the MMB29N radio on my Nexus 6P without losing my app data given that my bootloader is locked?

Flashing the radio -sadly- requires an unlocked bootloader.
Did you resolve your problem?
In android 7.1.2 did you notice in Set preferred network type is set at " LTE/GSM/CDMA auto (PRL) "? 7.1.2 has been giving me issues with sms/mms. I noticed Android 6.0 has this set to correct T-mobile bands.
All works for me in 7.1.2. Make sure you don't download the Verizon version of the stock ROM. That was my issue why I couldn't have volte and Wi-Fi calling

I'm in Japan for a couple of weeks for work and signed up for the Japan pack that Sprint offers. I spent almost an entire week working with Sprint support ( ) trying to get data roaming working properly on the phone without much luck (voice and text worked great), but yesterday I lost all connectivity but wifi. Figuring I must have changed something I shouldn't have, I saved everything I could and did a hard reset on the phone.
It still won't connect to any networks. I've re-downloaded PRL and device configs over wifi in the settings but it doesn't even attempt to connect to any wireless networks, or see any for that matter.
I have 2 guesses here but I'd like some kind of confirmation here before I take any action.
1: Maybe my radio firmware is corrupted somehow? I'm not exactly sure how to check it but it just doesn't seem to be doing much of anything. In the SIM status page it says searching for network, but I have no way to know if that's really the case.
2: Since the phone has a Sprint SIM, does it has to be on an actual Sprint network to initialize the networks? (Not Softbank's network here in Japan?) I spent over an hour on Google Voice with them last night trying to get an answer/help but got absolutely nowhere.
The phone is currently all stock but I have no problem unlocking and installing recoveries/software/roms if need be. Any ideas what I can do here or am I just stuck without communication until I get home next week?
Usually the best route is to get a local prepaid sim while traveling but honestly I have no idea what sprint offers for roaming in Japan. Check your plan and see if there is an add on needed.
I'm not alone!
Also THIS IS STILL AN ISSUE!
It worked fine for me last time I came to Japan, about a year ago. This time, I only have voice and text, no data. Right now I'm backing everything up to do a factory reset.
Did you ever find a solution to this?
I'm not sure if you've already done your factory reset, but if you're on Sprint, don't do a reset. The phone can't reactivate itself off of Sprint towers. You have to be in the US when you do the reset. I was stuck with WiFi only for most of my time there because I reset mine.
I never found a solution other than dropping Sprint when I got back to the states. Switched to Verizon and never looked back, though I'm not sure what I'm going to do for my next trip with their ridiculous international rates.
I actually got it working last night.
Factory reset and restore over wifi
Update device config over wifi -> handles activation
Update PRL over wifi 3 times
Now it works
Oh, I'm glad it worked. Is yours on Sprint?
Yes, but I may have spoken too soon. It worked for a few hours and now isn't getting back on data. I think it may be SIM related, since I saw a weird SIM error pop up and rebooted my phone, which led to the data working the first time
They must have redone their activation system since I had my issue in July. At that time there was no way for the phone to reactivate without being on Sprint's system.
As far as the data, that's the same thing I had happen and they were never able to solve the problem. It would work for a little while then stop for no reason. If you find a solution I'd love to hear it though.
I'm wondering if I can flash a different radio or something
Does anyone know what this letter C like deal is between my wifi symbol and my call signal ? I was going to ask dottat big D but it seems we have lost him to the forum. He will be missed he was always a good contributing member and a good friend to many of us including myself. He will not easily be replaced and he will be missed. Best of luck to you D a lot of us appreciated everything you did for us.
Now on what I have going on, mine is an unlocked htc 10 s-off unlocked, verizon picks it up as a verizon htc 10 for reasons we are not supposed to discuss on here, so what was done is flashed the verizon htc 10 radio and such as Dottat has on his thread, but what I think is going on is mine is picking the verizon signal up as roaming which it is not, so my problem is in the phone itself and not in my verizon service. The reason why I have it set up to be picked up as a verizon 10 is because I run it on total wireless prepaid which is $35 a month unl talk & text with 5 gigs of verizon data throttled to 5 mbps down and two up. If it was on a post paid account then I could activate the sim in another phone and put in this unlocked 10 and it would work fine registered as an unlocked 10, but for total wireless if you activate the sim in another phone and put it in the unlocked 10 you will only get 3g data I think its this way for all verizon mvno the only exception would be verizon prepaid.
So here is what I have tried I"am running viper10 2.2.0 the first time in viper set up while flashing I selected the phone as unlocked 10 which is where I"am back to because I tried flashing again and selecting the phone as verizon 10 and it was working great problem fixed until I find out camera wont work it turns on then right back off so I tried uninstalling the htc 10 camera app then clear cashe and reboot and re install it from the play store and same deal open the camera app and it closes immediately, then flashed viper again going back to selecting phone as unlocked 10 during rom flash, and camera works great again. I really do not want to convert to a verizon 10 as I like my updates from htc directly and not from douche bag verizon lol. Anyone know this issue ? I do not need to convert to verizon 10 as prepaid does not use Volte so converting is worthless and of no benefit. I dont know if the issue is firmware related but wouldnt you think the unlocked 10 and verizon 10 would use the same software for the camera ? It makes no sense. I guess for the time being I wont have a camera and if I cant find a camera fix I will wait it out for the new nexus 5.5 inch screen phone expected to be due out in a month or two. Anyone have any clue on a camera fix ? Because as unlocked 10 flashed viper10 it works great except the camera wont work at all ?
Here is a screenshot showing the C
I forgot to mention not only is my htc 10 trying to roam, it does not want to send texts they fail sending and that is even trying using verizon messages. And I tried flashing the verizon radio again each time after flashing viper10 and switching from unlocked 10 to verizon 10, and then back to unlocked 10 again to confirm camera was working right again which it was now I will have to flash viper10 again and once again set it up in flash as a verizon 10, have no choice, either my total wireless verizon mvno service works and camera does not or camera working and no service yeah thats a no brainer lol. So there is where I"am and no Dotat to save me this time lol
you cant use the unlocked option on viper if your going to use it on Verizon. the Verizon option in aroma flashes the necessary files to make it work properly on their network, like system apps, libs, apn info, framework files, etc.....
the camera breaks due to mismatched firmware on your phone. you need Verizon radio and firmware for it to work properly. flash the latest Verizon RUU and radio if needed and then reflash viper with the Verizon options. if your using it for Verizon the unlocked firmware and options no longer apply to you and are now on verizons time when it comes to updates.

Yeah I will pass on that I guess I can do without camera as I do not want to convert to a verizon version. I like my updates quick and clean from Htc and not from slow verizon who takes months so they can try to figure out extra bloat to add or any other ways they can try to lock your phone down more.
With viper10 2.2.0 set up as a verizon 10 then flashing the verizon radio everything works perfect except no camera so no camera is better to me than putting any nasty verizon software on my phone I dont even want their firmware nothing verizon that I absolutely do not have to have like my unlocked motorola nexus 6 is I get nothing from verizon but the call signal and their LTE data just as it should be.
I just flashed the 1.19.605..9_s_on RUU that Dottat provided for Verizon onto my Sprint HTC 10. Everything works great, except for one thing: the camera launches a black, flashing screen in any camera app. I'm guessing this is due to some mismatch of firmware on the device?
Here's the original thread: http://forum.xda-developers.com/ver...l-ruu-1-19-605-9-t3377586/page32#post69151435
Can anyone shed some light on this? I read on this thread here that people are experiencing this, but it isn't clear why, and what possible solutions might be...
I have been trying to get wifi calling with AT&T is working on my International S7 edge. I have made headway.
1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.

5. I am unsure if I need to make Buildprop changes or I am missing other system files. I was able to activate wifi calling and turn it on, but it doesn't work.

Did you ever get this resolved? So far I can not for the life of me, get WiFi Calling working on my S7 Edge exynos. Basically throws an error stating the activation failed, and never brings up the screen to enter in my emergency contact address like AT&T is supossed to re-direct you to.
The activation fails because AT&T doesn't have an AT&T wifi capable phone on your account which then allows you to activate the wifi. I have two imei's that are linked to AT&T s6 and s7. I can give you the imei. Go to att tech support give them the imei and tell them to update your account to be able to get visual voice mail and wifi calling. After you do this, they will alow you to activate it. However I gave up after a while. If you flash the custom csc, you must do it before your phone boots up after a factory reset and flash a custom rom. I am waiting as I am on Nougat now, so until ATT updates it's apps again.

Thanks, although I'm a bit confused on the steps your outlining here. I assume you're stating that I'll need to somehow modify a ROM (in this case SAC's N7 ROM for S7 Edge Exynos), and inject an IMEI? I'm not entirely sure how to do that to change the IMEI (this would be my first time attempting to do that). Then I would reflash that image, and then re flash the CSC update to AT&T? Maybe I'm not understanding, but my iPhone 6 is on my account and fully capable of wifi calling. In fact we have 2 iPhone 6s on the account. What exactly did you give up on?
Hate to sound like a newb here (although in a way... I am), but can you step me through the process so I can follow your line of thought? Appreciate the help!
So first of all an Android WiFi Calling and IPhone Android WiFi calling are different you will need to tell at&t you have an AT&T branded Android phone that has WiFi calling. This will lead at&t to add the ability to add wifi calling on your account.
Have you rooted your phone and installed a custom rom? If so then you would flash ttkg84's csc package and choose att. Which will flash most if not all the files. I got all the way to confirm my address and enable wifi calling, but it never worked.
Do not insert another phones imei into your phone, you will brick it and will have a expensive paper weight.
I have given up for now and am waiting for a full release of Nougat.
PM my I can give you am imei to give AT&T to enable video calling, visual voice mail and give the ability to activate WiFi Calling, but it's not likely to work. Some things are still missing.
You may never get wifi calling working because at&t uses a slightly different method then everyone else. I think they will standardize with Nougat.

That's what I thought.... So what about the King of Nougat ROM that's lingering out there currently? I realize Nougat is still beta, but have you tried the beta?
I haven't tried King of Nougat. I am currently using Nougat? Are you on telegram?

So... Interestingly enough. I just got WiFi Calling to work this morning...
Basically, I did the following steps:
1. No SIM Inserted into Galaxy S7 Exynos - SD Card only
2. Reboot to Recovery
3. Wipe
4. Download and Install SAC23's Full n7 ROM located here: http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358 - I did the V8 Debloated version
5. When prompted - Wipe Dalik
6. Insert SIM Card from AT&T iPhone (ensured WiFi Calling was turned OFF on the iPhone prior to removing from iPhone)
7. Reboot first time into N7 ROM
8. Go through the setup and connect to a WiFi location that you know WiFi calling works at.
9. Download a browser (Chrome or whatever) at a minimum
10. Eat a Bacon, Lettuce, and Tomato Sandwich :good:
11. Reboot to Recovery
12. Flash CSC for the N7 located here --> http://forum.xda-developers.com/note-7/development/utility-flashable-csc-selection-v1-0-t3450911 - Grab the CSC snapdragon the Exynos zip
13. Reboot
14. Status bar will indicate VoLTE enabled up at top eventually.
15. Try going to the pull down from the top, and clicking WiFi Calling option a couple times.... no dice.
16. Try going to the phone app --> Click Settings --> Note WiFi Calling is off --> Try clicking it on a few times.... you'll get an adroid app stopped working.
17. After sitting on this sceen for a few minutes, note the VoLTE dissapears, and the icons on the phone app screen (The Call Start Button and the Call End button) switch to WiFi magically.... Try making a call with 0 zero cell reception, and indeed, the call is being made through WiFI on AT&T's network.
Now.... I have absolutely zero idea what's going on with the VoLTE icon disappearing.... and the WiFI calling suddenly working. If you reboot the phone, the same thing occurs. It starts in VoLTE.... and then eventually disappears, and eventually after a couple of minutes being connected to a WIFI connection, switches auto-magically to WifFi calling.
I'll take some screenshots.

Followed the method above using Superman 1.16 and CSC selector 1.86.
Haven't been able to test wifi calling since I haven't found an area with wifi and no cell reception, but so far everything looks like it's working.
Important to note that the AT&T account probably does need to be provisioned for a G935A rather than G935F, which is done by reporting a G935A IMEI to AT&T (and not changing it on the device itself) as mentioned previously.

Hmmm, gotcha.... but if you report a G935A they typically want you to power off and power on the phone to check the provisioning while on the phone with them. And what happens if someone calls in and then tries to re-provision the same IMEI on another account? What happens to my SIM in my G935FD? Thanks!

Far as I can tell they don't check IMEIs against different accounts.
I can't say for sure, but I haven't had an issue as my phone has a different IMEI (or IMEIs--G935FD) than the one listed on my account (which reads as a G935A).
In short, asking AT&T to change the IMEI on the account hasn't affected or changed the IMEIs on my phone, or caused any problems.
As far as provisioning, I told them I was on the phone, so they called me back a few minutes later and didn't report any issues or discrepancies to me.
It'd be just as easy to tell the rep the phone isn't available though, so just ask them to change the IMEI and you can call them back later if there are issues if that's a concern.
Looks like great news. I was happy I was able to activate my 935F via AT&T (I gave them the actual IMEI and they activated it). I'm on Superman ROM and flashed ATT CSC. I get visual voicemail and the WiFi calling button, but it doesn't actually work. I'll see if I can get a valid 935A IMEI and ask them to activate again. Hopefully that will do the trick. I get a horrible signal at home, and the 4G/LTE icon is constantly flickering on and off... AT&T Video call option shows up in settings, but won't turn on... no wifi calling setting in the settings menu, just the quick settings button.
Any guidance appreciated!

Hi, I just picked up on those Amazon Prime phones, LG V35 unlocked. I was sure it would work with project fi and even project fi said it would work. Well, it really does mostly work. I was able to activate it and do just about everything, but I noticed 2 things:
1. No option to enable wifi calling
2. No access to visual voicemail.
I figured I could just install the regular google phone app to gain access to those things, but the google phone app doesn't enable that stuff. And when you make a call, it appears to switch over the LG phone app.
I don't see why this shouldn't work with Project Fi, but I have no clue how to enable those things. Calling on Tmobile and sprint work, texts etc work, it's just those two things that don't work
Would really love to use this version since it's quite a bit cheaper than buying the Fi version.

I don't have this device but, the following thread looks like the same/similar discussion than your question for the same device. It may be helpful for you.

Good Luck!

Same exact situation here...times three. I bought three of them for family members hoping there would be some way to make the Amazon V35 fully-functional on Project Fi. No visual voicemail would be acceptable, but lack of wi-fi calling is a deal-breaker for me. Any idea if it's even possible to get that working on this phone?
Ironically, wi-fi calling IS installed on the phone (visible by viewing installed system apps), and when I am in an area *with* wi-fi but *without* cellular service, it is trying to connect to wi-fi calling but can't with an "ER081 - Unable to Connect" error.
Any options here?
Thanks much!
Thanks ! It looks like it's just a matter of removing a couple of the lg apps and replace them with Google apps, like the dialer. I don't know if this is even possible or not so I may just return the phone. It would seem like just replacing the dialer would make a big difference though....

I have the At&t V35 and I was able to install the Google Dialer directly from the Play Store. This is the first non Google device I've ever used that let me install the official Google Dialer from the Play Store. It really does make a big difference.
Can you remove the Amazon stuff?
Ok, so I made some project on this -- I got visual voicemail working. All I did was download the phone app, made it default for phone , gave it some permissions and I got all of my visual voicemail.
As for wifi calling, I can't get it to work. I downloaded google connectivity services (strangely, you can't search for it in the play store, but if you do a web search, you'll get a link to it in the play store), I gave it all permissions, etc, and actually I got ONE wifi call to work, but after that I just keep getting "ER081, Unable to connect." So wifi calling doesn't work and I'm not sure what the trick is to make it work. Everything else SEEMS to work, but since wifi calling doesn't work, I wonder if there is anything else that is broken that I'm not seeing.
I don't think you can remove the Amazon apps but they aren't intrusive at all. I got this on prime day and I'd keep it if I could get that wifi calling to work :/
How do I test Wi-Fi calling. Have the same V350ULM on verizon.
I have been playing with hidden settings but really don't know what I am not I am doing and seems like a lot of damage can be done in there using the "Nova Launcher" using the activities widget.
Warning: can really mess up the phone. Be careful and let me know what you find. I am also looking to enable video calling on Verizon.
Thank you
So I got this device from Amazon, and I've had nothing but issues with it.
Originally got it for Verizon, as it says on the Amazon page that it supports the Verizon network, which is partially true. I can make calls and texts and use data on the Verizon network, but literally don't get ANY of the advanced calling features, such as Premium voicemail, or WiFi calling, which is what I needed.
After looking into it, I determined that it was becuase it was an unlocked phone, and I am just not going to get those services to work on the Verizon network.
So my thinking was to switch carriers to Google Fi, since all they do is service unlocked phones. I got the SIM card yesterday, downloaded the Project Fi app, activated and ported over my number from Verizon. All seemed good, except as soon as I finished activation, I kept getting hit with this WiFi Calling Error: ER081 "Unable to Connect".
I first attempted to use only WiFi to do stuff on the phone. I turned on airplane mode, then turned on WiFi, and started testing. I first sent and received SMS and MMS using the standard Android Messages app, and that worked fine.
I then attempted to make a call, and it failed. The phone app wont even attempt to dial out, as it states that 'Airplane Mode' is enabled. That Error: ER081 keeps popping up.
I've been dealing with Project Fi support for the past 12+ hours now trying to figure this out, going through all the BS, they wanted me to install the Hangouts App and Hangouts Dialer, and that works over WiFi, so they were trying to say problem fixed (only if I use that app). That is not a solution.
Has anyone had any better luck with this device on any other carrier, with ALL advanced services and calling features functioning 100%?
I feel like this is a carrier service issue, and not a device hardware issue.

For me it worked if I reset the phone back to stock, and turned it off. Put the Fi SIM in, went through setup, installed the Fi APP, let it do it's config thing, THEN tried to make a call. For me it then worked on WiFi.

KennynGGG, just want to confirm something. You flashed a ROM onto your LG V35 ThinQ? How did you unlock the bootloader - has some kind of exploit been discovered?

Well, being a noob and all I wasn't sure but are you saying that the bootloader has to be unlocked in order to flash any rom in cluding the same Rom Albeit different carrier ?
I just got me a V40 ThinQ thanks to Sprint. It's full of bloated stuffs though, I've never had a branded phone before or may be other company aren't as bad.
Anyway, I want to take a rom dump from the V40 and see if I can give my V35 a run before I send it in to LG for warranty repair. But when I tried uppercut to launch LGUP it still says the dll is out dated. I've tried it with my dll from V35 extraction. still not taking it. Any suggestion ?

I just finished flashing the Project Fi firmware to my Amazon V35 and it all went fine. Going to assume it's a simpler flash since the 2 are practically the same, even the firmware share the same version number. Before doing a factory wipe I tested WiFi calling by turning airplane mode on, wifi back on and made a call. Worked perfect. Did a factory reset on the phone to clear all the Amazon bloat and noticed that when the Project Fi app was activating service, it auto downloaded a sprint file/profile which I had never seen before.
I pulled the LGUP dll from the firmware and also modded it and LGUP for developer options. I only had to pick upgrade for it to work and was surprised how quick the flash actually was. I won't ramble anymore, but if anyone wants I can upload the modded dll and lgup exe that I used to flash.

No problem, hopefully the zip file with the modded files is attached correctly to this reply. It's for LGUP 1.14
My phone was listed as V350ULM10f after the latest OTA update last month (I think it was just a security update). But that's the same version I used for the KDZ. I grabbed the firmware from here:
Firmware
Hopefully it works for you too.
Edit: Also forgot to mention, I had to put the phone into download mode for it to work correctly. Power the phone off, plug the cable into the PC, while holding volume up plug the usb cable into the phone and once you see download mode, release volume up. Then launch LGUP and it should find the phone and be good to go.

Thanks Ibuprofen...I'll definitely check those out this weekend....I noticed the V40 Dev mode has "OEM Unlock" an option to turn on or off but that's probably isn't going to do any good without fastboot.
Bloatcrap
I currently have the Amazon 35.... Are you telling me I can get rid of all this bloatware just by flashing the original firmware?
If this is true I could kiss you on the mouth.
There is a Wi-Fi calling check box, but nothing seems to happen if I check it, and it doesn't seem like the essential APKs are there to make it work. Does anyone know if there is a way to make it work?
Also, is there a surefire way to test if it is working -- ex. should true WiFi calling work in airplane mode with WiFi turned on?
If it's unsupported on the unlocked device, is it known if it's possible to flash the Sprint rom to enable the feature?
It works perfectly well on my unlocked device in the UK. It does depend on your carrier, though, as to the support they provide and their requirements.
I have an unlocked PH1 on Sprint right now. Wifi calling works perfectly. If you are using a custom ROM, you will typically need to modify build.prop to add in support, but it does work. You may need to flash back to complete stock to go through the Sprint setup. This is done to update PRL and other odd files Sprint uses. Can't update those on a custom ROM. You can confirm if it is working or not by looking for the highlighted icon.

When I first put my Essential on Sprint, I could not activate Wifi calling, Went in to "About Phone", "OMADM updates" and updated PRL and Profile, that was no help.
I called support twice, and couldn't get it to work. It wouldn't let me turn on wifi calling.
I went back to it 2 weeks later, and it is now working perfectly. I work in pretty much a basement with no Sprint signal, but get Wifi calls just fine now.

That's very helpful. So you didn't complete any sort of Sprint related setup with the Sprint logo on it, right?
