Cannot call at several mobile phones

[Gon]

hi all,

Some weeks ago it suddenly came an issue on my PinePhone with calls. When I made a call, it rang the first tune, but later it hung up, simply it stopped calling. I use Mobian OS on it.

I've been searching for any sollution , but I can't find any. I've tried installing several OS, like PostmarketOS phosh, and Manjaro Plasma Mobile, even Postmarket Plasma Mobile. And on all of them it keeps the same issue. I've noticed that when I call on some mobile phones (always the same), it only rings the first tune and hangs up, but if I call on another mobile phones, it simply runs and makes the call ok. Calling to the landline it works fine too.

It is really strange, doesn't it? Should be a problem on the PinePhone itself?

it may not be o.s. related. it may be eg25g firmware related and volte. so i recommend updating firmware either stock or partially open source firmware.

https://github.com/the-modem-distro/pinephone_modem_sdk

if stock firmware, i recommend 30.007.30.007 version.

i recommend these for both stock and partially open source, https://github.com/the-modem-distro/pine...ETTINGS.md .

Ok, thanks so much for your input. I'm researching on Mobian, trying to install the stock firmware recovery with fastboot, like they tell here:
https://github.com/Biktorgj/quectel_eg25_recovery
But finally it keeps on terminal telling <waiting for any device> without success.

I've keep on searching. I've opened an issue with this on github web. I'll tell you my progress.

Well, finally I've found the sollution.

I read the text on this web, trying to install PinePhone Modem SDK:
https://github.com/the-modem-distro/pine.../tag/0.7.4

Before installation, I made sure that adb and fastboot where installed on mobile phone.

Then, I downloaded ADSP version 30.007.30.007 like @zetabeta told me.

I got into the folder on terminal where I downloaded the .ubi archive.

Later, like a root, type: 

Code:

echo -ne "AT+QFASTBOOT\r" > /dev/ttyUSB2

Then, run:

Code:

 fastboot flash modem NON-HLOS.ubi && fastboot reboot

And then, when I restarted the mobile phone, it started to type several changes which lasted about 15 minutes (more or less, because I left and then came in and saw the mobile ready). I just left the phone charging in order to prevent some crashing during the flash mode.

When I got into mobian again, all is running perfectly, and I can make calls ringing tunes normally, and receiving sms and everything.

Thanks so much for your help @zetabeta
