Note 8 Unlocked Missing HD VOICE and VIDEO CALLING

I am uncertain which information is true or false, but thought I would ask here. I realized I may be missing a few features when I bought the unlocked Note 8. However, I was under the impression that I could somehow enable things like HD voice and Video Calling.
If I am able to do this, can someone provide a link to a guide I can follow for the Note 8? I realize there are third party apps. But, I was hoping to achieve the above naively.
I'm Currently with AT&T, but prefer the ability to Hot-Spot by using an unlocked version of the Note. Hopefully someone who has enabled this can chime in.

I currently have an ATT Note 8 and I have a similar question. I want to flash the unlocked firmware so I can use it on T-Mobile. I've looked online and couldn't find an answer hope someone here can help us.

So my understanding is that AT&T only allows things like HD Voice, Video Calling, VoLTE, Wi-Fi Calling, etc. On their branded device's. It's why I actually didn't get the unlocked device even though I previously had a Note 7.

This was my understanding as well, but, I thought someone came up with a clever way of enabling these features. Hot spot and the ability to jump carriers were more important features than the others... which is why I went with unlocked. Am stuck in an unlimited data plan with AT&T for one more year. Unfortunately, they don't allow any kind of hotspot with unlimited plan.

Since the phone just became available and only to few people (BTW I'm still waiting), you guys have to wait , because since all those are hacks, phones have to get to right hands and then may take some time to figure things out, unless any of you have enough knowledge, then head to S8/S8+ forum and try using those solutions on your Note 8, may even work.

When I booted my Note 8 with T-mobile sim card, it applied some carrier customization and enabled VoLTE and WiFI calling but video calling is missing which I don't use much anyways.

You can usually do this via the service modes:
Dial *#0011# may work
Press the Menu key and then Back
Press Menu again then Key input and enter the value 1.
Wait a little
Press Menu and then Back
Press DEBUG SCREEN
Press WB-AMR SETTINGS
Press WB-AMR ENABLE
This use to work on previous models.
(In the UK being shafted by a long wait for my Note 8)

I thought many of the methods wouldn't work since AT&T uses whitelists on their system and it's not just the features are missing from the OS.

I tried the *#0011# and was able to get all the way to debug. That screen or option is not showing up on my unlocked note 8.

I know the S8 crowd has been flashing the carries specific CSC/CP files through a modified ODIN on top of the UNLOCKED firmware. I'm sure this will work on the note 8 as well. The modem should enable all the carrier specific bands and the CSC should enable the wifi calling and VOLTE. on a side note, check in the settings menu for the wifi calling. when I flashed the T mobile CP over the U firmware, I did not have a WIFI calling quick toggle but I did have wifi calling the in the regular settings menu. I had to toggle it on and off that way.

Are you on an old grandfathered in AT&T unlimited plan? I have a new Unlimited plan and they offer lots of goodies including a 10GB/month hotspot for each phone.
Check them out: https://www.att.com/plans/unlimited-data-plans.html
You should not be stuck in any plan now for a year or any time frame. Change when you want to change.
Here's a link to information for Flashing the Unlocked Firmware and Carrier Switching on the Snapdragon S8+ (no rooting necessary). https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680
Probably going to be similar with our Note 8s.

Im on Verizon and I cant see wifi calling or HD voice aka VOLTE. Maybe we just need to wait.

This may help for people looking for video calling

I had to download the app "shortcut master". Navigate to to IMS Settings, click RCS Configuration and enabled everything. I also can see the WB settings under "DM Configuration" under the IMS settings but they are relabeled as xxx_WB and instead of enabled/disabled, it is a 0 or 1. I believe the 1 is enabled. Probably need to restart as well but I am uncertain.
The outstanding question I have is do I need to change HD_VOICE under the DM configuration from a 0 to 1 as I see that there as well.

I downloaded the shorcut master. However when i try to change anything, it says SU: not found. I also saw in there about the HD voice enabled. But am not able to launch any type of editor. I have the note 8 unlocked version, using straight talk sim card on verizon towers. I would love to be able to talk on the phone and surf the internet at the same time.
anyone able to get this working on the unlocked version?

I have video calling & HD Voice working on unlocked model with VZW SIM on gUDP, I almost had WiFi Calling working; but broke video calling. I'm hoping to get both working; WiFi Calling works with T-Mobile SIM out of the box. I haven't messed with my AT&T SIM to see if any of the features work; but maybe this week I will.

How did you get video calling working. I still have yet to successfully place the call.

wifi calling

I got a n950U1 unlocked note 8 ( not rooted) which is a snapdragon version. I am not living in the states but bought my mobile in my holidays and was wondering how to get wifi calling on this phone. My carrier has it available as i was using it on my previous mobile, and can still use if i use my sim in iphone. I heard that the t-mobile version has it but how can i activate the setting or get an apk which can enable this setting for me? Is the app completely missing or any secret setting needs to be enabled?
Or is there a different way to enable this feature? I know that the N950F version has it but why not this one? I wasn't aware that there are differences in such options.

Also unlocked N950U1 is able to use wifi calling.
If not yet upgraded to Oreo, you can enable Wifi calling in IMS settings, using Shortcut Master app. (Search this forum for thread)
Setting will then be in Phone/Calling app, not in the general phone Settings.
After Oreo I no longer can access the IMS settings, but luckily Wifi calling remained enable after FW upgrade.

I have tried to enable via shortcut master but the app itself to make wifi calling seems to be missing. There is no setting to enable in IMS settings

I also have SM-N950U1 and I have NEVER seen or found the WiFi calling in this device, regardless of version Nouget or Oreo. I have read also a few months ago that using Shortcut maker it "should" be able to work but I also have had no success with this. You are able to find bits and pieces of WiFi calling but no actual app for it to work.

As I stated, the setting is in the Phone / calling app. In Shortcut Manager look for "WfcPref".

Not really a solution but more of a bandaid , maybe resort to flashing the t mobile firmware if all avenues have been exhausted?

I also have checked that option but there is no actual app launching, it is all tutorials or help files. I suppose it is not included within the firmware. Or maybe it is because i haven't initialize it with a t-mobile sim card. I was just hoping that maybe there is some sort of apk app by which we can have it.
This is all i get in shortcut master

Just to add also the phone/ calling app screenshot and the connections/ more connections screen

Here is what i noticed.
Note: I'm on note8 exynos csc xme
I use dual sim.
Sim1 do not support wifi calling
Sim2 supports wifi calling
I have wifi calling setting to switch it on only when i switch everything to sim2, data messages and calls.

It's restricted by 2 factors. Your telco and csc.
Obviously to have wifi calling ur mobile operator must support this and allow ur phone number to use this function.
Second is the csc of your phone. Some branded phone restrict this, they do it via csc code. U can look around on this forum there is ppl that manage to decrypt the csc files edit it and load it back. Root required for this.

Hi again,
My telco has it as i was using on my iphone. The problem is with the note 8, There is no functional app or apk for this when i do a search on shortcut master. After rooting will i be able to get the wifi calling app from somewhere after editing the csc?
Or is it much easier if i change the firmware with tmobile branded and then use my phone with it. Do you think i will get the app then by editing the csc file?
Or will it still not work as it is t mobile branded.
This is so annoying, it should have been much easier and with much more freedom, why is this wifi calling even missing as app, they already can disable if the telco doesnt support it. I never had such issue before

With Note 8 N950U1 you should have wifi calling without any problems.
Check with T-Mobile site how it works and what to do, i.c. check the requirements.. Did you put in 911 address?

Hi vash
My wifi calling is working well on sim 1 until I change this sim card to slot 2, then changed call/text and data to SIM 2,
(because I inserted SD card with 2 sim cards now, my another sim card was issued by another country, cannot get new one, so I cut the SIM 1 and moved to SIM 2)
Then wifi calling disappeared, it's gone..
Looks wifi calling will be working on SIM 1 only.

I'm sorry.
WiFi calling is working for SIM 2 as well.
Depends on the WiFi internet connection quality.

yup.. wanted to ask you to check internet connection quality. if the connection is not good wifi calling doesnt work. most of the time when i am overseas, hotel wifi is not good enough for wifi calling.. thus kind of useless for me.

Yes, thanks.
But probably not only internet quality, I think carrier will check some certificate or something.
Because no WiFi calling icon when I'm using the employee WiFi in office, I logon with my user name and password, and sometimes public WiFi is also not working for WiFi calling,

On the main screen click on bottom left call icon to make a call. Then go to setting on top right 3 dots down. You will see wifi calling enable or disabled. You can turn on or off. If it can help someone. I was looking everywhere and it didnt help, but eventually found it. It's not in connection and more setting like some place stated.

Unlocked S10 on T-Mobile - What works and what doesn't?

Would like to know if anyone has confirmed what all works, and what doesn't when using tmobile's network on the unlocked s10.
I've heard things like 4x4 MIMO , VOLTE, carrier aggregation, etc may not work.. Also supposedly slower updates... But if someone can confirm this.
Also, would flashing tmobile's firmware onto the unlocked s10 enable all network features I would get on the tmobile model???
Thanks!

I am pretty sure the only missing item is T-mobile video calling in built-in phone dialer when you use unlocked US snapdragon variant(still bootloader locked) on T-mobile. WiFi calling, VoLTE, 4x4 MIMO, CA works just fine. Yes you can flash T-mobile's firmware if you want video calling (and bloat).

Could you provide some basis on where you got this information? If you have some solid confirmation that would be great.

I have S9+ unlocked and this applies to it, so I am pretty sure the same will be the case for S10+.

Samsung has a compatibility table on their site, and it can corroborate part of VICosPhi's post. The bit about MIMO and CA (up to 5 or 7) is not written explicitly. Unofficially you will achieve these, however.
The phone also supports ALL LTE bands for T Mobile (minus 2 rare ones). 2, 4, 5, 12, LAA, 66, and 71. By flashing the TMO CP I think others restored RCS and video call, haven't really looked into it.

Yes. This is true from S8 onward.

This has beem covered before in this forum.
Radio-wise, side by side, 970U1 reception is not as robust as 970U firmware. YMMV per local radio deployment but it's pretty obvious here where I am (Alexandria VA, DC. metro). I have several 970U1 (Best Buy), but have flashed all of them with 970U because I prefer full T-mo functions and better reception. There's not that many TMo bloatware, and all can easily be disabled with PDP or AH3.

1) Did you flash full firmware(including USERDATA file)?
2) Also did you use CSC or HOME CSC?
3) Have you used regular/standard Odin or Patched 3B?
The reason for my questions is that I flashed my unlocked S10e with T-Mo firmware, but it didn't matter is I flashed userdata file and csc or home csc, there was no T-Mo bloatware. I do know that firmware did flash properly, as the phone did get built-in video calling, T-Mo RSC(advanced messaging), 4G LTE signal logo(didn't see T-Mobile Digits in the settings though)

When I go to phone app/dialer, there is no setting for Caller ID or Spam Protection. T-Mobile's Visual Voice Mail app has a setting to enable "Enhanced Caller Information" and I did enable it in the settings. My phone does show if it is a spam call or like today, it showed a call as "verified" when someone was calling me. I did check T-Mobile branded phone in the store and settings are the same as on my phone. There were no extra options that my phone was missing. Also as you may already know T-Mobile's S10 devices don't have "Multi-Line" settings which would support Digits option in the phone's dialer app and also no VVM that is built into the dialer as well. T-Mobile/Samsung might/might not bring these features in the future update

Before flashing my unlocked S10e, there was a setting in the dialer about caller id info. Carriers possibly remove these features as they do offer their own. For example when I access my T-Mobile account settings online, there is a toggle for some spam protection. The caller ID was or is paid service. As for the HD voice, I think unlocked U1 firmware has it, but just doesn't advertise it during call as T-Mobile firmware does. For example U1 firmware shows LTE and LTE+ on the status bar, but T-Mo firmware shows 4G LTE sign, but they both get same speed and connected to the same network. I remember there was a dial code that would show as some voice codecs that handset supported, something like *#0011#, *#1234#. Haven't played with those for a while as I was using Pixel phone

Thanks for the information..
The caller ID and spam protection is the smart call feature built in the phone. It's like free caller ID. Different than the one you talking about.
Definitely not hd voice I compare side by side my s10e exynos voice quality.
Wondering if possible to flash u1 firmware but flash userdata from tmobile? Or even TMobile baseband.
Edit so I was able to flash the latest U baseband on my u1 firmware. I was actually able to change the csc too in the phone using the *#272*imei# code to xaa/xxa/tmb and it stuck. But after I rebooted once I can't replicate that and it always goes back to tmb/tmb/tmb because of my t mobile sim card.
When I was in xaa/xaa/tmb I could see the volte toggle was on. Still didn't show the HD voice icon while in call.

So my S10e at the moment is TMB/TMB/XAA. It shows HD+ icon during calls. You won't find VoLTE toggle (as on U1 XAA firmware), but VoLTE is always on in T-Mobile firmware

Yes, U1 firmware had the toggle, but T-MO firmware doesn't, but I do know that VoLTE is always on.
Before I put my sim card into the U1 phone, it was XAA, but when you put T-Mo sim card, the phone gets some carrier info and restarts. After that it becomes TMB/TMB/XAA even without flashing. If I wouldn't flash my phone with U firmware the Video calling, T-Mobile boot logo, HD+ voice icon and 4G LTE icon, Advanced Messaging(T-Mobile's proprietary RCS) won't be present with standard U1 firmware

Is there a way to get xaa/xaa/tmb with a TMobile sim card in it?

For those who use Verizon MVNO's VoLTE Now works after Update!

I have a Verizon S9 with flashed T-Mobile firmware from back when I had it on Metro, which has the Verizon bloat from inserting a Verizon sim, anyway I use RedPocket CDMA Verizon on this phone now, and apparenlty VoLTE was broken last year after an update and there was work arounds like enabling emergancy mode and swaping the sim and it would stay until reboot.
Well Glad to say the new July update, it now has VoLTE!! There is now an option under Mobile Networks for VoLTE. And it works!
One strange thing though now instead of it showing Verizon, as the network it shows "Roaming Indicator off" which its not roaming. But just glad to VoLTE now works!
Another note: This T-Mobile update doesnt show avalible yet online? but yet it updated.

I wonder if there a way I can get where you are. I have a tmoble s8+ and put a verizon sim in to switch it to verizon and then switched that for my red pocket sim and VOLTE option shows in the menu but when I go to the *#*#4636#*#* menu also available through forceLTE app I see VOLTE but its grayed out. Also just as weird is that wifi calling is switched on and I cant turn it off. DO you have wifi calling on and which firmware are you on? I am on security patch level april 1st 2019.. Maybe I need to get your update and that will do it, but I show no update available.

Maybe I need to get your update and that will do it, but I show no update available.

You might have to manually flash the update. But the April patch doesn’t have it for the S9 anyway.
I don’t think redpocket does WiFi calling volte setting is under mobile networks

Is your software ver PPR1.180610.011.g955USQU5DSD3?
Yeah red pocket does not support wifi calling or video calling that is why I cant figure out why that is turned on on my phone. I just want VOLTE to work. I have it in the network settings menu just not on the field test mode 4636 menu and when I make a call no VOLTE.
I might just start from scratch with oden and download the latest verizon image. My CSC says VZN/VZN/TMB. Is that what yours says? granted I know your on an s9 but the s8 and s9 and even the 10 are really similar with there software packages.

YeAH i Know the guys on telegram say most of the stuff works the same between the 3 phones with only minor differences..
This has to be what your talking about.. https://9to5google.com/2019/07/25/g...ng-out-w-july-security-patch-qr-code-scanner/
Here is the reason I believe Im not seeing the update.. https://thedroidguy.com/2019/06/wha...-plus-wont-install-downloaded-updates-1081849

Son of a... awesome.. Ok so I re-enabled auto pre-config.. See here: https://forum.xda-developers.com/ve...0v-success-t3558214/post79937998#post79937998
THen I put in a tomble sim and got the update for july. Im downloading it now. I thought that disabling auto pre-config would be a good idea but I relaized the verizon is so anal that they would not allow me to get the update because my phone is really a tmoble branded. Anyway tmoble will give me the update then I can auto preconfig back to verizon and be using VOLTE... THANK YOU for your topic.. finally got it..
---------- Post added at 10:23 PM ---------- Previous post was at 09:56 PM ----------
Unfortunately I'm not getting as lucky as you are. I cant get on VOLTE, I cant even get on CDMA now with my red pocket sim. Ill keep working on it and see if anything else needs to be done, maybe a reset. I got cdma and i think ill have to disable auto pre config.

I wanted to post another update to those who are using an MVNO verizon or possibly other carriers, for s8-s10. I was finally able to get VOLTE to work but you must flash the matching carrier firmware, auto pre config will not work when using an MVNO. I Flashed the verizon firmware for my tmobile S8 and got the verizon modem file which I think made the difference. My CSC changes to vzn/xaa/tmb. Use odin and flash the CSC or CSC home and everything else in the other fields minus userdata. CSC will erase userdata, csc home will not.

Restore Call Recording to your Note 9 SM-N960U and SM-N960U1

Purpose: The Google Play Store policy change in March has destroyed this critical functionality for many. Prior to that, using Pie produced very poor quality recordings compared to Oreo. This is how I restored call recording functionality. I will add any noteworthy contributions to this first post to make this easier than it has been for me. Many people have pulled their hair out with me to come up with this. This is simply a consolidation or our trials and errors.
This only works on Note 9 models SM-N960U and SM-N960U1 phones with boot loader version 1. To determine if you can use this procedure:
1. Go into Settings/About Phone to find the model number. It must show SM-N960U or SM-N960U1
2. Then click on "Software Information". On the "Build number", the 5th character from the right must be a 1. If it is not, this procedure will not work for you. If you don't own the phone yet, make ensure it is a 1 before you buy it.
For the SM-N960U model, this procedure will replace your carrier-specific firmware with US Unlocked firmware. It is not possible to prevent the carrier-specific firmware from updating to Pie and forcing other unwanted changes on your phone because it does not have the Blue "Software Update" program (com.wssyncmldm). When you finish, the model number will be changed to SM-N960U1. This process is reversible by flashing the phone with carrier firmware and using the standard ODIN version for that firmware.
The ramifications of moving from the carrier firmware to US Unlocked firmware are:
1. You will be able to flash to and remain on Oreo vs. being forced to Pie.
2. No carrier specific apps are flashed. (USERDATA which some refer to as bloatware)
3. Depending on whether the carrier's service is standards-based or not determines whether or not US UNLOCKED firmware will be able to make their services available.
- Verizon: No VoWiFi (Wi-Fi Calling). Everything else, including HD Voice and Carrier Aggregation work fine. My old phone didn't have it and coverage was never a problem, but if you travel, Wi-Fi calling means you have free calling to and from the US from anywhere you have an Internet connection. That could be prove quite valuable even if later you plan to get a local SIM.
- T-Mobile: Everything works except for roaming US Cellular's network. They have good coverage as of late, and the cheapest and 2nd fastest data.
- Sprint: Some users state that they retained Wi-Fi calling but I haven't heard many confirmations. I would guess if they have that, they also have VoLTE. I haven't heard about carrier aggregation, but if they do in fact have the other two, they probably have it as well. Again, my confirmation has been weak here.
- AT&T: No VoLTE or Voice over Wi-Fi. I haven't heard about carrier aggregation but it clearly doesn't play well with US UNLOCKED.
- after flashing U1 firmware. Wi-Fi calling is useful where you have no cell reception but you do have Wi-Fi and can save you a TON of money in roaming charges or purchasing an International plan. If you cannot get Wi-Fi calling and this is a requirement, you may want to cut out Android, carrier, and phone manufacturer altogether and read If they ever destroy this ability again at the end of this post.
4. You will need to download any carrier specific software you want from your carrier.
DANGER! On the "Build number" you are about to flash, ensure the 5th character from the right is a 1. If you flash one of the newer "U1" Pie updates that has a version 2 boot loader, you will never again be able to flash any version of Oreo, because they are all on version 1. You cannot flash a boot loader back to version 1.
Preparation Considerations:
- WARNING: If you use SmartSwitch to backup your phone, DO NOT press the update button when doing your backup!!! If you do, and it updates your boot loader to a newer version, it is the same as bricking the phone for someone who needs call recording because you can never be able to return to Oreo 8.1. OTOH, SmartSwitch is the only backup program for a non-rooted device that can restore almost everything back the way you had it. Download the setup.exe for the SmartSwitch for Windows, and the APK from APKPure.com. I copied both to a folder on my SD card so that I will always have a matched pair and I can restore without connecting to update software to execute the restore, and you may not want newer versions in the future. Install SmartSwitch on Windows and the phone. Before you do the backup, disconnect and forget Wi-Fi. The reason you want to do this is when you restore the phone and settings, it will also set up Wi-Fi like you had it and it will connect. The problem with that is by default SmartSwitch will start updating everything to the latest before the phone is in a position for you to stop it from happening. With no SIM or Wi-Fi, the phone interface settles first. Then you can put in the SIM and go to the play store and turn off Auto updates and notifications. The SIM doesn't become a problem as rapidly.
- I also recommend using pre-2019 Helium Backup apk and installing it as well as the Windows app version as well on your PC. Helium is more complicated to use, but is very flexible for restoring single apps such as using ADB, which works on any Android phone. Another reason you need it is SmartSwitch will only restore to a Samsung device. A Samsung device might be available or what you want when you need to do a restore. I have only 6 weeks with the Note 9 and have used Helium on my previous phones, so I'm still evaluating if Helium is what is best for the Note 9 and Oreo.
- Consider making a Downloads directory on your SD Card with sub-directories with .apk files that you will want to have available during or after setup, or are in danger of being ruined by an application upgrade so that you can readily restore them if necessary. For instance, mine contains a pre-March 7, 2019 version of SmartSwitch, old version of Helium, Automatic Call Recorder v5.43.11 or earlier, Automatic Call Recorder Pro v5.43.11 or earlier, etc.
Make these slight adjustments to the excellent procedure listed in the first post here: XDA: Confirm These Steps to Downgrade US Unlocked SM-N960U1 from Pie to Oreo
1. Prior to step 7, perform a factory reset from within Settings/General Management -> Factory data reset. If you do not, after flashing the phone, it will force a SIM or Wi-Fi connection to make you log in as a theft protection measure, during which time your phone will begin performing updates before you are in a position to implement measures to stop them. When you perform the factory reset from within Settings/General Management, it had to have been performed by someone who was logged into the phone and thus allows you to skip installing a SIM or enabling Wi-Fi during initial setup script, which in turn enables you to prevent any updates from occurring until you have made your changes.
2. Prior to 13, Do as minimal setup as possible, making sure you turn Wi-Fi off and Skip Wi-Fi. You will not be doing a restore, setting security, or setting up any accounts.
2. After 13.
a. Follow the steps shown here YouTube: HOW TO STOP FORCED OTA UPDATE NOTIFICATION from 0:25-1:49 to change app settings for both Software Update apps found in Settings/Apps and from menu select "Show System Apps". In "Battery", turn off "Allow background activity". In "Notifications", turn off everything. In "Apps that can change system settings" turn it off, but do not go past that point in the video or reboot as the video states to do afterward.
b. Back in Settings/Apps and on menu select Show System Apps. Go into Security Policy updates. In "Battery", turn off "Allow background activity". In "Notifications", turn off everything, and On lock screen set it to Do not show notifications. In "Apps that can change system settings" turn it off. *If this process runs, it aligns the phone's policy with that of the Play Store. It will not automatically update offending software, such as your call recorder, but it will list it. If it lists it, you are toast because the new policy, now implemented on your phone, will cause the now non-compliant previously useful software to hang when you try to use it. I know of no other option than to re-flash your phone and do a restore from a backup or start from scratch.
3. Reboot the phone and go into Settings/Apps/Show system apps, and ensure the Blue Software Update still shows disabled.
4. Prior to 15 install the SD card and install the SmartSwitch apk that was downloaded earlier to your SD Card using the Samsung My Files file manager.
*The following three item numbers must happen rapidly: (Have your play store credentials handy.)
5.. Insert the SIM to gain Internet access, not Wi-Fi if possible.
6. Go to the Play Store and immediately go into into Settings on the left side menu and turn off:
a. Automatic updates.
b. All Notifications
7. Go to your phone in Notifications and cancel all updates. Note: You will want any app updates to happen manually. Some will be affected by the March 2019 Play Store Policy changes that will ruin their functionality. The app developers usually will mention if there are functionality changes due to the new policy in the description area for their apps. When you go into play store and select My Apps, it will show you which ones need updating and you can decide which ones you can update and retain their functionality.
Restore Call Recording. (I use Automatic Call Recorder by Appliqato, but you can make adjustments based on the same logic.)
a. DO NOT download your software from Google Play. Sideload Automatic Call Recorder by Appliqato, sideload version 5.43.11 from an .apk from a Helium or some place like apkpure.com.
b. If you have a Pro license, restore that will need to come from a backup of version 5.43.11 or earlier. You cannot buy a Pro license any other place than the play store at the moment, and the one from Google will be too new.
Reboot and ensure all of your settings are still intact and fix any that are not. On the Blue Software Update icon, it should show a status of disabled next to it.
Going forward:
1. Backup your device with a program that can restore a single application. I've been using Helium, previously named Carbon. It is clumsy, but it makes compact backups into ZIP files, and the backup are stored as .apk files, so you can simply side load to do a restore of the app and data. Make SURE you tell it to include the applications because by default it expects to download the latest version from the play store which is NOT what you want. SmartSwtich is for changing phones or full restores. It is not a substitute for Helium.
2. Backup the PC area where the software to restore your device, firmware, and APKs are to restore your device.
3. Do not use the play store unless you have to. I've been using APKPure, but there may be other good ones also. This enables you to get older versions, which is critical for many critical apps. As I mentioned earlier, you cannot do effective call recording with the current call recording software from the play store. Look for dates prior to 2019. This also pertains to using SIP/VOIP clients because they don't allow them to access your phone book to dial with, and thus cannot keep a useful local log either. Having the APKs enables you to reinstall at any time. What you need may no longer be available from the play store in the future.
If they ever destroy this ability again, for $15/mo. to CallHippo and a data-only SIM, you can send Google, Android, and control on your life by your wireless vendor packing, plus you will have your recording, calling logs, and Voice over Wi-Fi via VOIP anywhere you can get a data connection, plus it is backed up forever. No more number porting, and if something happens to your phone, simply need to buy another phone. The only capability it needs is a data connection, so even a computer, tablet, or SIP phone will work. There are many other advantages as well. Multiple devices can respond to the same number and multiple people can answer and be talking on the same number. The only thing any of them will see is a secure connection to your VOIP vendor.

IT, thanks for this detailed post. I just want to clarify something you might want to update. Ramifications #3 for migrating to U1: wifi calling DOES work on T-mobile (but not volte), and it sounds great!

Thank you for the feedback. I've mentioned before on other threads that T-Mobile users are the only ones talking about Wi-Fi calling working on the U1 firmware, but I forgot to include that here. I will add than now.
However, I do have a few questions:
1. Did you flash the T-Mobile U1 firmware or the US UNLOCKED?
2. How did you activate Wi-Fi calling? Did it just work, or is there a place in the Interface in the T-Mobile U1 Firmware to put in your address?
3. Why do you believe that VoLTE is not working? VoLTE is digital voice, as is SIP/VOIP, Wi-Fi Calling/VoWiFi. VoLTE is part of the LTE protocol suite that came with LTE-A, which has been implemented on phones since the Note 4. An LTE network is a data-only wireless network just as the Internet's IP network is a data-only network. Voice cannot travel either network unless it is digitized. Wi-Fi calling (VoWiFi) requires a service at the carrier which negotiates the data stream source with your phone and transitions between wireless and the Internet without dropping the call to your carrier's PSTN server where they host your number. It's tough for me to accept that you have the far more complex VoWiFi without VoLTE. If using connection monitoring software your phone shows only an LTE connection during a call, VoLTE is being used and your nice clear calls are no mystery.
Thanks!
PS: There is only so much practical spectrum suitable for cell phones. In the US it is the FCC's job to responsibly manage the growing demand for that space. When carriers want to license bands from the FCC, there are ALWAYS catches. They made Verizon share a band with T-Mobile. Verizon and Sprint are not shutting down CDMA on their timeline, it is on the FCC's timeline for some deal they made that is part of their band licenses because it frees up those bands for LTE.(Verizon EOY 2019 and Sprint EOY 2020) Similarly, providers are telling customers that they will not support phones on their network without HD Voice/VoLTE (Added with LTE-A) past...(Verizon EOY 2019). They will GIVE you a phone, and maybe even tape money to it, to get your old phone off and keep you as a customer. The FCC isn't allowing them to suck up bands that can only be used for analog voice calls. Carriers cannot do carrier aggregation that way either to where they can balance traffic across multiple bands so they don't have some over utilized while others are under utilized. LTE-A Rel. 10 of 2011 already enabled up to 5 bands to be aggregated up to 100 mbps. For carriers like Verizon it is panic. They know there is no point in approaching the FCC for anything unless they can prove they've optimized what they have. The T-Mobile and Sprint merger is a beautiful thing. It's like sewing a head onto a body.

1. I've read that U* firmware is carrier-specific, here in the USA, except for U1, which I have, which is USA unlocked and unbranded (no carrier). I bought the phone new with U1, un-branded, no carrier firmware, so I did not flash anything. It came with Android 8 and I immediately let it do all of its updates to bring it forward to Android 9. I think that was in June. So, no, not T-Mobile. U1 unlocked. (Love this--very little bloat, and I've used adb to disable some apps as well, namely that FaceBook TRASH)
2. There is no access to Wi-Fi Calling in the settings, however there is a Wi-Fi Calling toggle in the toggle drop-down, and I've confirmed that it indeed does switch Wi-Fi calling on and off, by walking in and out of my home wireless area while in a call and watching the Wi-Fi icon on the call screen appear and disappear and hearing the quality become very clear when on Wi-Fi calling and get less clear when switching to the carrier network.
3. I am not sure about VoLTE, because there is no toggle or VoLTE setting in settings. I had never really tested it or cared, but I just now tried a test. I downloaded the "LTE Discovery" app to see the band my phone is connected to, in realtime. I am on LTE band 4. I am at home and connected to my internet over wifi. I placed a call to my wife, and it was going over my wireless (wifi icon in call screen). Not the right condition for this test, so I turned off my phone's wifi. I then placed the same call, confirmed his call was not over wifi (and must be over the carrier network) and switched over to the LTE Discovery app to see if it had connected to a non-LTE band for the call. It was still connected to the LTE Band 4 that it was connected to before the call. I might assume this means that VoLTE worked. Even still, I don't know how to test further, since there doesn't appear to be anything that allows me to turn VoLTE on or off. Nothing in settings or no toggle in the toggle drop-down. One thing that make me hesitate to fully believe that that test call was VoLTE is that I believe Band 12 is the only band that is LTE-ONLY..... if I could make a voice call while on that band, then I think VoLTE must have been working (?). But I don't know if the LTE Discovery is doing a great job of connection monitoring for Band 4... I mean, is it possible it would show LTE Band4 while placing a voice call and switching to a non-LTE connection? I don't know.
Hope that helps!
Also, thanks for the intro to VoLTE. That helped me understand VoLTE better.

That's interesting. I'm on Verizon U1 US UNLOCKED connected to Wi-Fi and don't have it, but that's not a surprise. It would be interesting to see if it works on T-Mobile U1 8.1 US UNLOCKED or U1 8.1 T-Mobile. My guess is if T-Mobile, if it works with 9.0 it will work with 8.1 since phones have supported Wi-Fi calling for a long time. It would also be good to know your build number from About Phone/Software Information and what it shows in Service provider SW ver. in ???/???/???.

If you go to the menu and select "System Network Setting" it will show you hidden screens and show you if VoLTE is turned on. If you go into System Info/Feedback, you can learn quite a bit about your phone that doesn't display in settings. Is Worldphone set to True or False? It would be interesting to see what Network Cell Info Lite shows on the Device-SIM tab in the Device Telephony area, and what shows on the RAW tab when you are in a call with Wi-Fi on and off during a call. Where I'm at LTE is inescapable. You can learn a lot by using Network Cell Info in concert with Force 4G LTE which can force any band, not just 4G LTE. Set it at some old supported protocol for your network in Force 4G LTE, and make sure Network Cell Info shows what you set it to. Then switch back to Auto and see that it returned to the default. That will give you confidence that Network Cell Info is showing you what is actually going on when you make a call. Eh...conversely, when you are finished playing around, make sure you set Force 4G LTE back to Auto, and confirm in Network Cell Info.
Thanks!

Gonna read through this and respond in a sec, but I came back to this thread to report something I found. Using QuickShortcuMaker, I was able to find and launch "com.android.settings/com.android.settings.RadioInfo". This gives a bit of interesting output and lets me toggle "Wi-Fi Calling Provisioned" and "VoLTE Provisioned". I have previously hunted for VoLTE in the settings menus quite exhaustively and never found anything, so this is great (also, both were toggled on). There is also a "Video Calling Provisioned" toggle, but it's grayed out.
Software Info screenshot attached.
So, "System Network Setting" and "System Info/Feedback" are not in settings men, so you'll have to give me a hint where to find these, because I don't know what menu you were referring to.
Trying the "Network Cell Info Lite" app now. Ahhhhh, there's the "System Network Setting" menu you referred to.
And going there only takes me into my android settings "Mobile networks" menu with no hidden anything. I'm fairly sure this has to do with the csc I have for the unbranded U1 rather than carrier branded csc. CSC controls what gets shown in menus. I went through this with my S7 Exynos version when trying various cscs and even modding my own to force wifi calling and volte.
On to "System Info/Feedback". I'm attaching a screen shot of that too.
Okay. I installed Force 4G LTE. Great tools! I'll good advice. I'll go play now.
Side note: I write backend software for sustaining a nationwide fiber transport and ip layer backbone, and I'm a stickler for engineers being precise, accurate, and thorough. Well done, IT!

Oh one more thing. Screenshot of com.android.settings.radioInfo

Allowed Network Cell Info to read phone state. World phone = false
Uhhh... I just kinda realized. This is hijacking your thread.

GET THIS THUMBNAIL OFF OF HERE QUICK!!! It has your IMEI number on it.
The thread is about call recording and of which preventing migration to Pie by using U1 firmware is required. Any way that can also restore Wi-Fi calling on U1 firmware is what everyone wants. Using the U1 firmware with the T-Mobile SIM works, but it is also needed for Verizon and others where that doesn't work.

thanks.. ya i meant to scroll my screen up a bit more to cover my phone number and imei.... it's getting late, and I should probably get off the interwebs.
went and read up on what someone could do with my imei....
anyhow... I installed "Force 4G LTE" by DevAppliance, and maybe that's not the app you were referring to... it didn't seem to do what you suggested.... and there does seem to be a few apps out there that match that name... what's odd is by clicking on the one of two options, the one that should have let me force 4g... it loaded the com.android.settings.radioInfo I had originally come back to this thread to report... the one that actually shows the hidden VoLTE and WiFi Calling Provsioned toggles (and yes the one I screenshotted of my imei, ughh). What are the chances? Really odd!
Oh, and then I uninstalled it, because it's basically useless, besides tons of junky ads.
So what's the developer that makes the Force 4G LTE you referred to?

I posted a bad link and just now corrected it.

btw U1 or any U firmware are muti csc. so i a sense even if you have never flashed a crarrier branded frimware, their CSC is still in the odm partition part of your device. the bloat apps arent on U1 of course. now the question is how are they able to ascertain if u are on U1 or not. because at this point it is not the blacklisting of the imei on non carrier bought device from using advanced csc features as people with U carrier bought phones have reported that after flashing U1 they have either WFC or volte not working( or in some cases both).

1. I'm going to toss out VoLTE because just because people say it isn't happening, doesn't mean it isn't. I've proven in a couple of instances now. If they call and only LTE is active during a call, it HAS to be using VoLTE. LTE cannot pass voice any more than IP can without it being digitized. IMO the FCC wouldn't allow carriers to communicate with LTE-A phones where they have an LTE-A network available, even if they wanted to.
2. IMO, Wi-Fi calling is the only one left standing and that we can prove only works on the U1 firmware for T-Mobile and Sprint. On the same phone, if you insert in a T-Mobile SIM your have Wi-Fi calling, and if you insert a Verizon SIM it goes away. Network Cell Info Lite shows this in the attachment that VoWiFi and ViLTE are not available with the U1.
3. When we flash Verizon's carrier-specific firmware, ViLTE and VoWiFi are available, once you fill in an address, VoWiFi must actually be standard SIP/VOIP because it makes no sense for a cell phone to have an address and an address is a VOIP requirement.
4. When you flash ANY carrier specific firmware, the the Blue Software Update icon does not show nor does ADB have access to it. USERDATA also implements the Security Policy of the carrier.
5. The next question is can VoWiFi and ViLTE be turned on remotely without a firmware upgraded. If I were to guess, I'd say yes. I already found the VoLTE hidden screen Network Cell Info Lite and I'd guess that Wi-Fi Calling is also in the base firmware that can be activated, and because it would make good business sense to be able to activate it on all devices from a flag change in a central location. When USERDATA is present, it references that. I base this on the fact that T-Mobile and Sprint activate VoWiFi and Verizon does not when no USERDATA is present.
Just a guess,
Next questions:
1. Referencing the attached picture, what determines whether or not a phone is a world phone? It's carrier unlocked and has more bands than any other phone but states it is not a world phone.
2. Do US phones incur limitations on non-US networks if they support the proper bands?
3. Do "world phones" work on US networks?

For those with a U1 unbranded variant who cannot load com.android.settings.radioInfo from their Settings menu, you can can just create a shortcut using Nova Prime launcher or some equivalent. You can use it to turn on/off Wi-Fi Calling and VoLTE. You can also use it to force your radio to connect to different bands, with more control than you get through Settings > Mobile Networks. You do not need a special app like "Force LTE Only" to do this.
Just make a shortcut to com.android.settings.radioInfo, also labeled "Device info".

I'm on the latest 8.1 U1 with Verizon SIM installed and I do not have that. What are you on?

The build date is 2018-12-14 - N960U1UEU1ARL1 and with the Verizon SIM installed, which makes a difference too. If you make no other changes other than plug in a T-Mobile or Sprint SIM, Wi-Fi Calling will appear before your eyes in real time.

Hi gruuvin,
This thread and the one it references is by and for users who need to remain on Oreo 8.1, and this thread in particular, focuses on regaining usable call recording abilities. Android 9.0 Pie cannot do clear call recordings, and the spring 2019 Google play store policy update has destroyed people's ability to have the usable call recordings that has affected phones at least back to KitKat. These surprise malware attacks have wiped out not only the ability to to have meaningful call recording going forward, they have also destroyed previous records that they used as the a basis and proof of service for their invoicing. To us it is worse than ransomware because you can't even pay the ransom. It has also been people's automatic note taker for projects so things don't get missed, and the basis and backup of invoicing for professionals who invoice for their time. Some simply used it to not have to interrupt the flow of the conversation to write notes, and especially while driving. Moreover, often you do not know when the conversation is held if it's details will become significant later. People have been relying on this ability for many years and it was the deciding factor when choosing between Android and the iPhone. If they could use Android 9 Pie, and trust Google play store policy updates, they would not have flashed from their carrier's U firmware to U1, and investigating the possibility of a work-around to regain Wi-Fi Calling. At the moment, the only networks I'm aware of that support Wi-Fi Calling using U1 firmware's native abilities are T-Mobile and some indicate Sprint as well. This MAY be because they got into it early and as a result do not have a standards-based implementation, and must be handled by the carrier's USERDATA in the U firmware.
Thanks!
