Google Pixel 3a (sargo)

@dieharddan What could work is the following:

Reboot into recovery
run:

adb shell mount /system_root
adb shell mount /system_root/var/lib/lxc/android/android-rootfs.img /tmp
adb shell rm /tmp/system/halium/etc/ofono/ril_subscription.conf
adb shell umount /tmp
adb shell reboot

In the booted system you can then remount read-write and replace the preset:

wget -O ril_subscription.conf https://termbin.com/k3gb
adb push ril_subscription.conf /home/phablet/ril_subscription.conf
adb shell

In the shell enter:

sudo mount -o remount,rw /
sudo mv ril_subscription.conf /etc/ofono/ril_subscription.conf

After that: reboot.

This will be overwritten by updates until confirmed it fixes your issue, then I will merge it. It seems to provide much more stable connectivity on sargo with my provider.

@fredldotme Can you elaberate on the "remount read-write and replace the preset:"
I entered the "wget -O ril_subscription.conf https://termbin.com/k3gb" on the phone terminal which worked, but not the
adb push ril_subscription.conf /home/phablet/ril_subscription.conf

nevermind i got it to copy over

dieharddan

@fredldotme Doesn't seem to have made any difference, I still have to toggle airplane mode to get sms to work

fredldotme

@dieharddan I can only suggest experimenting with the config or, if that doesn't fix it, adding fallback behavior to ofono in case receiving SMS fails.

dieharddan

@fredldotme Ok, let me know if you come up with any other ideas; I will pllay around with that file but not being any kind of developer, I probably won't be able to accomplish much lol

fredldotme

@dieharddan What you might also want to try is the two properties ro.ril.power_collapse & ro.ril.disable.power.collapse, these might change the behavior of the power savings mode.

Reboot into recovery
Connect phone to PC
Open an adb shell with adb shell
Enter the following commands:

mount /system_root
mount /system_root/var/lib/lxc/android/android-rootfs.img /tmp
busybox vi /tmp/system/etc/init/on-post-fs.rc

In vi enter edit mode by pressing 'i' on your keyboard once
Paste the following content at the end:

on init
    setprop ro.ril.power_collapse 0
    setprop ro.ril.disable.power.collapse 1

Save and exit by pressing ESC + entering :wq
Run umount /tmp
Reboot

@fredldotme No change Is there something I can capture via log while i toggle airplane mode and send texts

@dieharddan
Based on what you describe I think that some process or daemon crashes after some time.
When switching to flight mode you probably kill clean this faulty code.
And when activating the modem again it works... until it crashes again.

I cannot help debugging that because I know nothing about it. But best bet is you can find errors in some log.

Best of luck

I can't seem to get the os working or to boot on my pixel 3a. The ubports installer says sargo isn't supported

fredldotme

@Duhjoker it's not officially in the installer yet. What you can do instead is follow this mini guide right here to force the installer: https://mobile.twitter.com/fredldotme/status/1322714885076275201

fredldotme

@Duhjoker the Pixel 3a is now officially in the installer, should be easy to get going now! Make sure to downgrade your phone as per instructions first.

@fredldotme after various attempts installed it on GP 3a with the ubports-installer. But having the incoming sms problem described by @dieharddan. Also, Airplane mode on/off enables incoming sms temporarily. Any ideas on how to fix it?

Hi, im new here hello to everyone, i just flashed on my sargo from the UB installer beta 0.7.2 on windows, and im happy to say that everything is working well for now, no problem with sms sync and cellular data at the moment, the only thing is that mms not working but maybe its my apn settings.
iam happy to try it very good works thanks.

Etn

@Etn i can confirm now that mms work send and receive

@Louie Could you please try the following:

Download https://drive.google.com/file/d/1T_00cBUyWrB3V-QLFxWPbmguYQ-gEdOn/view?usp=sharing
Copy the file to the Downloads folder on your phone
Open a terminal with adb shell
Run:

sudo mount -o remount,rw /
sudo cp /home/phablet/Downloads/libgbinder.so.1.0.47 /usr/lib/libgbinder.so.1.0.37
sudo reboot

Also interesting for you, please try to replicate the change here:
https://gitlab.com/ubports/core/rootfs-builder-debos/-/merge_requests/18/diffs

In case you don't know how to do this:

sudo mount -o remount,rw /
sudo nano /etc/init/ofono.override

Remove the provision, from the file and save (Ctrl+o and enter, then Ctrl+x to exit) and sudo reboot for good measure.

Please make sure to try the combinations separately, if any of the changes fixes it it would be interesting to know which combination it was, so please remember that and let me know!

Is it hard to get UT on a Pixel 3a? I think I tried to root it, and it was having issues. I'm fairly tech savvy...just not in this area of Android and Linux.

fredldotme

@Nathan123 rooting is not required but you need to unlock the bootloader. Follow this guide to unlock it: https://android.gadgethacks.com/how-to/unlock-bootloader-your-pixel-3a-0198625/

After that follow the guide, including reverting to the last Android 9.0 factory image and installing via the UBports Installer.

@fredldotme Thanks for your kind help :smiling_face_with_sunglasses: . I tried both options in different order without success. However, when turning airplane mode on messages come through after around 40 seconds. Then when turning airplane mode off message can be received for a few seconds. Please let me know if there's anything else I can try...
