i think you can start with whichever correspond with the lineage os you have running and see how far you get

sounds good, thanks for the feedback— we'll also improve the docs (or if you would like to help with that, the repo for the ubports docs is at gitlab.com/ubports/docs/docs.ubports.com)

since halium 9, we have a halium GSI, which means we no longer need to build halium per device

Halium

if you look at https://docs.halium.org/en/latest/porting/get-sources.html and https://docs.halium.org/en/latest/porting/build-sources.html, there are sections for 5.1 and 7.1 and not for others, I was really confused about that

Halium

30 October 2025 15:48

the section below that describe basically what treble does

I was trying to build halium because I thought if I succeed it would help debug ubport problem. But docs are really confusing about versions, looking at this table for example my first thought was using halium 13 because the device supports los latest versions, but now I see this is wrong. Nowhere in docs I think "treble" is mentioned, so I dont even know what is pre os pos-treble.

I'm already running lineageos. I tried ubports, managed to generate imgs but got bootloop. Them I tried halium 7.1 and halium 9.0 with lineageos repos for 15.1 and 22.0, got a lot of errors, fixed some, and couldnt generate any image. So I wanted to make sure which versions of halium and lineageos repo should I try to focus on.

Halium

it means it has it unofficially, possibly via lineageos

Halium

but seems erfan did make a treble port: https://xdaforums.com/t/treble-port-android-9-0-pie-gsi-for-moto-x4-20180731.3823878/

@fabricioakio getprop | free vndk

Halium

30 October 2025 13:44

huh the prop does say enabled and it does show a vendor partition—🤔

Halium

I think so, how do I make sure?

➜ ~ adb shell getprop ro.treble.enabled
true
➜ ~ adb shell ls -l /dev/block/by-name | grep vendor

hello, I want to install halium on an old device, motorola moto x4, which halium versions should I try? I can run the latest lineageos on it.

Halium

04 October 2025 17:31

Based on my understanding of the guides, that's correct

Halium

04 October 2025 17:29

Past 9 it is generally a kernel only build, Ubuntu Touch and Droidian have separate instructions for their respective builds

Halium

30 October 2025 16:06

nice. As I learn more I might give a try at at helping docs. But what do you suggest about halium version, should I start with 9?

Halium

30 October 2025 15:53

I think I will go back trying to run ubports now that I learned more about android and halium

Halium

30 October 2025 15:49

the halium docs are unfortunately outdated

Halium

30 October 2025 15:48

maybe we should use that term in there 🤔

Halium

30 October 2025 15:47

we probably should just remove 7.1 from that table then— look at the note below the table

Halium

30 October 2025 15:17

that could be anything including a problem in kernel due to configs you changed. if you didn't even get to rootfs yet changing halium versions etc randomly is going to get you nowhere. you probably should also refrain from going back to pre-treble stuff because that's largely obsolete and porting docs surrounding that stuff is now removed unless you specifically view an older branch

Halium

30 October 2025 14:33

I think you can install lineageos and then try following the target project documentation for building the kernel, the vndk would've told you which version is appropiate—

Halium

30 October 2025 14:31

what does that mean? It doesnt support treble originally? do I need to follow these steps to isntall android 9?

Halium

30 October 2025 13:56

no output for "adb shell getprop | grep vndk"

I believe it is upgradeable to android 8 from motorola, doesnt that mean it supports treble?

Halium

30 October 2025 13:45

it could have that unofficially as well (or from LineageOS builds)

Halium

30 October 2025 13:40

no, it shipped with android 7.1

Halium

30 October 2025 05:19

does it support treble?

Halium

23 October 2025 21:43

So that people here know, the Halium 7.1 / 9 Full System Image documentation has been removed from docs.ubports.com. For people who need it, a git tag was created of the last state of the docs before this change.

Halium

04 October 2025 17:30

well, I saw tutorial about 7.1 and there used vendor and device tree, so for 10 I need only kernel right

Halium

04 October 2025 16:29

so how port 10, is it different instruction?
