Halium 9 / CI + OTA build

rogier.oudshoorn · 3 Jul 2021, 13:27

The GSI build isn't likely to get updates, but there's a build in progress on the regular build track. You can find the setup here: https://gitlab.com/ubports/community-ports/android9/oneplus-6

Status
Essentially, we're looking for developers. The gitlab builds work, and are flashable, but the following aspects are missing / work in progress:

There's a kernel bug that breaks suspend; right now suspend is disabled (so it'll run through battery quickly) https://gitlab.com/ubports/community-ports/android9/oneplus-6/oneplus-enchilada-fajita/-/issues/2
Recovery is available, but non-functional (lacks functional ADB). https://gitlab.com/ubports/community-ports/android9/oneplus-6/oneplus-enchilada-fajita/-/issues/3
Camera app won't start
Features regular reboots
It generally lacks polish

If you're interested and capable of helping out, please join us on the discord here https://discord.gg/haVG9Ga

If you're not a developer, the GSI is more stable - but the CI builds feature a more recent rootfs. It's your choice.

How to flash
The CI build produces a boot.img and a system.img As you imagine, they're flashable through fastboot. Be warned - you have to flash on top of LOS 16, it won't boot on any other base.

You can download artefacts from the pipeline, right now this is the last merged build: https://gitlab.com/ubports/community-ports/android9/oneplus-6/oneplus-enchilada-fajita/-/jobs/993648342/artifacts/browse

I would just like to confirm you actually mean it has to be Lineage 16 and not any other Android 9 version that Lineage is based off of? Or do you just mean the equivalent version to LOS 16? If it has to be LOS 16 can you explain why? If it has to be LOS 16 does it matter which point release?

@antidroid @rogier-oudshoorn I'm down to begin this process. Is there a quickstart process or is it basically starting by cloning this and doing the steps? https://gitlab.com/ubports/community-ports/android9/oneplus-6/oneplus-enchilada-fajita

I've never done this before, but I feel comfortable enough to start figuring it out. That, and my only other phone is a Nexus 4 (3G) and I am not going back to Android on this. If I have to help build this up, I will. Those issues are not insurmountable. (Curious about the camera though... worth investigating.)

TotalRando · 8 Mar 2021, 03:00

@antidroid I am guessing because this is what @rogier-oudshoorn is using and therefore the standard "we can't guarantee the steps will work on other versions" verbiage applies here. I'm cool with not getting experimental during the installation process. Will look for LOS 16.

I am fairly sure you do not need to build anything. The last link Roger posted was a link to compiled images. A boot.img and a system.img
But again no instructions on how to flash other than Rogers comment on using fastboot. I would have thought you use the same technique as the GSI but since he says this is not a GSI I am not sure.

I would simply try flashing them as if they were a GSI but I am currently dual booting to postmarket on a custom Gnome build I am working on and do not want to risk losing the changes until I have my install-able version matching the changes I have made on the phone directly. You can always reflash the phone back to stock and start over.

@antidroid It's not a GSI. It's a Continuous Integration system (CI). Kind of like a pseudo-central base to withdraw from.

Like an artificial speed force.

I get that but the two files the Roger linked to in the last link of his post are the same types of images as used for a GSI (system image and boot image). As to how they are flashed I was guessing it is like flashing a GSI but again the lack of documentation leaves us to guess.

I think the difference is that is more like an edge build. The continuous integration means it gets patches and updates pushed to it and are built to test for problems but does not create actual files so they are not installed on devices. The files he linked to were created 6 days ago but if you look through the jobs you can see it is simply the last successful build from a month ago being made into actual downloadable files.

You'll need to run exactly LineageOS 16, not just any Android 9 version. I presume this is because LOS changed some of the partitions, and we need it to load their drivers, but i'm not sure. I'm running on the latest LOS16, and i suggest everyone does the same.

Yeah, exactly! Please download the system.img and boot.img artefacts from the CI job - CI will do the building for us.

It's not a GSI, and you need to flash with fastboot instead of twrp. IF you're on the right slot ( you can check with fastboot getvar current-slot ), the steps are:

fastboot flash boot boot.img (flashes the boot.img to the boot partition of your current slot)
fastboot flash system system.img (flashes system.img to the system partition of your current slot)
fastboot reboot (reboots your phone on the current slot)

@rogier-oudshoorn

So the XDA page for the official LOS 16 Oneplus 6T build release points to the files on the Official Lineage OS sites download page for the Fajita which only has Lineage 17.1 builds.

On their FAQ it says this

We don’t keep building, or keep builds around for any version older than 2 Android versions (e.g. when 18.1 builds started, 16.0 builds stopped and the builds were slowly removed,

So we need an OS that you can no longer get unless you build it yourself or trust some shady download portal someone has uploaded the files to before they were scrubbed from the official server. Just to flash it before flashing a test build of UT.

I may try flashing it over Oxygen just to see and if it fails I will run Postmarket until there is a proper install-able version of UT. The current GSI is completely useless for me. I get a couple of seconds of screen time before it shuts off the screen. I can reboot UT as many times as I want and the results are the same. The only way I have ever been able to get it back is to reflash Oxygen then UT and a few times I had to repeat that. Once back it last for a couple of reboots maybe and comes back. Reflashing Oxygen obviously ruins my Postmarket build so I just don not use UT on it currently.

I sense this won't work as I don't have the LOS 16 build....

Hmm new feature. I've entered "Crashdump Mode". This gives me the impression I have done something wrong.

TotalRando · 9 Mar 2021, 04:33

@totalrando Well, it's been fun. After a nightmare bootloop, I decided to start the process over. I downloaded OOS9 and am keeping it there... for now (apparently there's no download space on a 128 GB phone). If I do go back it will be to the GSI build or anything later. Still have UT on my Nexus 4, but I've had enough pain with this phone for now. Maybe I should have just left it as is. Maybe I'll go back to the GSI build if only to get my drive space back. I genuinely miss it. But for now, I'm just happy the thing places and receives calls.

Yeah, you should flash system.img to system, boot.img goes to boot ...

AntiDroid · 12 Mar 2021, 09:49

@rogier-oudshoorn So I decided to reflash my phone with Oxygen 9 to see if your CI build would work. It did not, it would just boot to the bootloader. But as you said it needs to be LOS 16 and as I said it is no longer available. So will you be providing a copy of LOS 16 for both the 6 and the 6T or will the installer provide everything needed to install regardless of the current OS?

sven · 12 Mar 2021, 18:47

BTW: The same version problem of LineageOS 16 exists for the Xiaomi Pocophone. Any long term archives of LOS?

rogier.oudshoorn · 13 Mar 2021, 08:26

@antidroid I found my copy of LOS 16 (for OP6) linked on XDA somewhere; i guess when we'll get to the installer stage i'll likely have fashboot or twrp flashable images for the installer to work with.

rogier.oudshoorn · 13 Mar 2021, 08:29

@sven This at least claims it does: https://archive.org/details/lineage-16.0-20200325-nightly-beryllium-signed

When you do, please check https://wiki.lineageos.org/verifying-builds.html to see if they are in fact officially signed.

TotalRando · 15 Mar 2021, 19:33

@rogier-oudshoorn Thanks for this. As my OOS9 build is virtually inoperable, I've moved my SIM back to my Nexus 4 but now I can start working on this wonderful phone again. Downloading LOS16 now.

AntiDroid · 15 Mar 2021, 20:56

@totalrando Rogers link was to a LOS16 for pocophone not oneplus 6/6T
