Device support (Project Treble)

harvey186 I see that you seem to know a lot. I installed a generic a/b treble image on my pixel 3a sargo. It works fine. but it says the base image is months out of date.

How can I manually upgrade it?

I’m assuming that to install GSIs on Snapdragon Samsung phones you still need to unlock the bootloader, in the conventional (paid because Samsung mean) manner…

Are there any problems with using GSI ROMs instead of official builds?
Is the battery and performance optimization not there?
And are there easy ways of fixing the notification bar, as it’s different for many devices and requires different margins.

Dead link now …
All GSI build have dead links, where to find a stable repository to have GSI build ?


This was to @e_poco_user 's builds. /e/team’s ones are linked in “week 19” (up page):

(follow ‘How to install guide’ link, then ‘scroll’ back and links sre in Flash system image)

Hello !

After installing an /e/ OS GSI (/e/ image ROM download) on a Sony Xperia X (suzu) (, I was informed that the microphone doesn’t work : during a call, the remote participant is heard just fine, but the local participant is not heard.

Here’s a log after a call using Signal, taken using MatLog :

I believe the relevant lines start here :
09-04 11:15:38.155 E/audio_hw_utils(16102): send_app_type_cfg_for_device: Could not get ctl for mixer cmd - Audio Stream Capture 16 App Type Cfg

And then :

… and for 2021 / 22

Thanks for the links and help. I read that the goal of the use of project treble is for testing, not for normal daily use. I would like to use it for daily use as a ‘normal’ phone user, because I want to degoogle my phone. Can anyone can give an advise if project treble is suitable for me or not? I use a Nokia 8.

So first we check Smartphone Selector, does Nokia 8 feature – not as yet! Do we see it in Search results for '#unofficial Nokia 8' - /e/ community – not today.

GSI is great for experimenters!

Will the Motorola e (2020) be added for use with your OS. I just tried the install and it is not supported. Also if I knew how to code properly I would gladly help your cause but being a 53yr old idiot at times I would not trust myself at times.
