L5 todays update-no more calls

antonis · May 24, 2023, 9:44am

After todays update I am not able to make or receive any calls.

When I try to call it tries to connect but then it hangs up.

I I try to call L5 with another phone it appears to be busy.

It also frequently shows only 2G and not 4G as it used to show. And the 2G has typically the exclamation mark.

This is kind of urgent. I need to use the phone. Anyone else experiencing the same issues?

If not I need to downgrade. But how to do it. I do not remember what it installed today. Running ls -ltr in the package folder it seems that probably it installed these:

What can I do?

steve · May 23, 2023, 2:43pm

Have you tried rebooting the phone again? I’ve noticed that rarely the modem can get in a strange state where it doesn’t seem to work for anything despite showing as ok.

amarok · May 23, 2023, 3:07pm

/var/log/dpkg.log

BTW, have you tried doing a restore from the Backups app? (I’m actually not sure if that reverts package versions, though. Anyone…?)

steve · May 23, 2023, 3:08pm

Those sound like seperate issues (I can’t reproduce either with the latest updates installed).
The poster appears to be experiencing an inability to make calls at all, and your calls seems to have no sound.

You likely checked, but I need to ask @guru, is your mic switch in the on position? I see volume on mine with the “Handset Microphone”.

I’ve seen what the op describes after several suspend/resume cycles when playing with the experimental suspend feature, which a reboot resolves. Could be something different though.

guru · May 23, 2023, 3:17pm

Thanks! I am an idiot, all is fine. I dialed our voice system and replayed the recording.

guru · May 23, 2023, 4:29pm

Can the calls app detect that the mic HKS is in off? If so, a warning for stupids like me would be good.

antonis · May 23, 2023, 4:44pm

Rebooted several times. No help.
All HKS switches are on.
I have never used the backup application. Maybe I should start doing this if it can revert packages.

Maybe it is better to see if a developer knows something about this case. If not, tomorrow I will try to revert the packages to the previous versions.

Thanks @amarok for reminding me the dpkg.log file. I will check that too.

a grep 2023-05-23 dpkg.log | grep upgrade
gave me this:

So I have to revert those…

sudo apt-get install ./linux-image-6.2.0-1-librem5_6.2.10pureos2_arm64.deb ./linux-image-librem5_6.2.10pureos2_arm64.deb

should do the job. Right?

antonis · May 23, 2023, 5:30pm

Just to add something in case it helps debugging:

I have mobile with 2G 3G 4G preferred. With this it connects to 2G. No calls work no internet.

If I switch to 4G only, I still have no calls but internet does connect.

steve · May 23, 2023, 5:35pm

Do you have volte enabled via the bm818-tools utility?

antonis · May 23, 2023, 6:00pm

Yes but it never worked. It always drops to 2G when in a call.

steve · May 23, 2023, 7:30pm

ok,
I suspect that non volte support got turned off in your area. I believe turning on volte requires cycling the modem (or just rebooting the phone) to apply. Could you try:

Enable Volte via the bm818-tools
Reboot the phone, or flip the modem kill switch to off, wait 30 seconds and flip it back on.

If that doesn’t work I’d suggest reaching out to purism support, they’ll be able to help with that better than I. You may need to update the firmware on your modem(any purism support knows how to do that).

antonis · May 23, 2023, 9:32pm

Thanks. I will first contact my carrier to make sure there is no issue there and then contact support.

I downgraded and it still does the same. So I suspect a problem with the carrier. Maybe the turned off something in my area as you say.

irvinewade · May 24, 2023, 12:37am

I would expect so and it seems like a warning would be appropriate - but it should in theory be valid to make a call, receive a call and continue a call even with no microphone. So the warning should be advisory but it should not stop you going ahead.

An added complication is that even if the mic HKS is off, you may have attached an additional sound source - and the operating system may or may not attempt to disable additional sound sources. In other words, the H part of HKS only applies to certain built-in components.

Xeda · May 24, 2023, 7:22am

Reporting back… I didn’t know about bm818 tools and it did the trick for me. The voice quality is way better via LTE.

(I’m in Europe)

janvlug · May 24, 2023, 7:40am

@antonis: What is your modem firmware version? Use bm818-fw-check in the terminal to check.
I have:

$ bm818-fw-check

Although I still do not have VoLTE working, it turned out that the problem was not with the phone but it was a problem with the carrier and their roaming. It turned out that last night travelling by car on Samos island the phone got connected to Turkey. This they told me locked the SIM. Next morning I upgraded the phone and then realized it did not work, and I thought it was the upgrade.

They disabled roaming on their system and a reboot of the phone solved the issue. Of course if I travel abroad I have to ask them to re-enable roaming for me.
So all this was a false alarm as far as L5 is concerned.

But to add something in the positive direction, I remember that some android phones have an option to lock the phone to connect only to a given carrier and not select the stronger signal. Maybe this could be a useful feature to be added.

As for the bm818-fw-check I get exactly the same output (except for the time on May 24)

Thanks everybody who tried to help me.
