Installing that package will not in and of itself cause anything significant to change.
You can run the tool to display the state of VoLTE.
Of course once you start changing the state of the VoLTE checkbox in that tool your leeriness should kick in.

That error usually just means that there is a stuff-up in group membership.
From the terminal prompt, obtain and post output from groups

Did you restart your phone after you installed the tool?

I imagine they only support the duopoly phones they lease out and shun freedom.
I think they know what the L5 can do - stop the abuses to our rights to privacy.

and I’m going to look up HSPDA and read a lot. Maybe it’s a answer too.
Ummm. I’ve no idea how to obtain anything in Terminal.

= “Run the command groups in the terminal, and then post the output here.”
purism@pureos:~$ groups
purism dialout sudo audio video systemd-journal render netdev feedbackd
purism@pureos:~$

And in case progress is made …
purism dialout sudo audio video systemd-journal render netdev feedbackd`
the bolded item is what you are looking for. If it is missing then
sudo adduser purism dialout
then reboot your phone
then re-check the output from the groups command
then if it’s correct, rerun the BM818 tool and see whether the error message “Failed to get Modem FW version” has gone away.
Then you could get back to doing anything with VoLTE.

Ahh. OK it reads:
purism sudo audio video systemd-journal render netdev feedback
so as irvinewade suggested below, I entered:
It’s missing so I typed:
and after entering password I get
The user ‘purism’ is already a member of ‘dialout’.
I rechecked by opening bm818-tool and it still reads
In hindsight and change of topic for a sec, I should have given the L5 a different name other than “purism”.

Did you “then reboot your phone”?
If a group is missing and you add it with adduser then there won’t be change to the output from groups immediately but you may have then gotten confused and executed the adduser command twice, in which case I can believe that you will get that message (The user ‘purism’ is already a member of ‘dialout’.) the second time.
So from here … reboot the phone and then check the output from groups to make sure that dialout is showing.

I put in a ticket with our own tech support who in turn talked to the Rogers NOC. Our guy was surprised and also not impressed with their answer then we started talking about the L5 and our guy thought it was cool. Linux nerds are everywhere, why don’t they just acknowledge us?
This is what the Rogers NOC guy showed our tech:
Notice how he refers to it as “unbranded”. Like you say not part of the big boy group so we’re considered “unbranded”.

It now shows “dialout”.
BTW - I didn’t add any groups and there are none. I don’t even know how to add a group. But I checked and:
Chats > [+] and only Group is “New group message.”
BM818-tools still shows the same:

IMO, they are ‘puppet masters’. If they don’t like Linux, maybe someone should help Rogers off the Linux servers they use.

Then I’m out of ideas for why that tool is not working but until you can get past that and get it to show you the modem firmware version, I recommend not attempting to do anything with VoLTE.
Maybe post the output from ls -l /dev/ttyUSB*

Got past it. I inadvertently forgot to plug it in last night. Plugged it this a.m. and started the L5.
I tried to open BM-818 but desktop was frozen. I pushed and held the pwr button down. Removed the battery (not that I knew what I was doing - just seemed cool at the time.) Replaced battery, booted and all was good.
Went right to BM818-tools and voila! I think the screen cap below means it’s all working. If so, now to send/receive a pic maybe.

VoLTE is for calling.

Something I’d like to add is that you’d have to go to Chatty and enable it in settings there…
