edit: latest 14.1 base out with fixed camera and booting
edit: alpha6 is out, sensors fixed, but camera is completely broken
So I finally have a decent enough port of SFOS on bullhead

Issue with install apps from the app store or warehouse?
need to setup password in developer options
devel-su pkcon refresh
Click to expand...
Click to collapse
also since store is sometimes a bit meh, you can use
https://openrepos.net/content/basil/warehouse-sailfishos
best way to copy files onto device is through ssh, setup password in developer options
store is sometimes broken, you need to do devel-su pkcon refresh in terminal, need to set password up in developer options.
OTA - Over the Air update
Best way to update SailfishOS is by using an ssh connection to the phone.
Disable all patches and Openrepos repositories before updating.
Before updating use
Set desired release version, for example 2.2.0.29:
ssu release 2.2.0.29

this wouldnt of been possible from the immense amount of help from the guys @freenode#sailfishos-porters

Really nice job! hope we can get all working in near future

Awesome cant wait to see stable build!

Can this be installed with multirom as secondary rom?

never tried it, didnt know we had a multirom stable.
on hammerhead it works fine as 2nd rom.

Holy crap this is awesome! I was waiting for a sailfish os port since I switched from my nexus 4. Is there a way for me (as an non-coder) to help you out somehow?
Oh and do you think it is possible that camera will work in the future or is this a missing driver code thing?

Yes there is a stable multurom on jolla kernel tread but in that case probably i will need to use the cm13 as primery rom to becouse of the vendor.

OMG a New Rom i don't know sailfish Os wow i go to try it
Thank you very much for your work

Really nice, sadly i need the camera for my work so i cant use as DD

Not a rom, it is a completely different operating system so no android apps.

the camera thing is a 32bit/64bit issue atm so i'll see were I get with it, am also messing around trying to get sfos working on a Huawei P9
No android apps at all, we have sfdroid, but its not working on cm13 as far as I know.

Very cool indeed, def hope this goes further. Remember it on N5 and was awesome

It's a nice ROM. But on my N5X the WiFi and Data isn't working.So sad.

That was my fault, issue with PARANOID_ANDROID. New image thats been upped should fix the issue

Ah... So it seems that its source is based on cm13 built in 161222, then should I use December mm vendor or January mm vendor?
(Sorry for my bad English...)

December probably.

And I know I'm bothering, but another question...
Is this rom doesn't contain boot animation? Cuz I saw cm13 booted well, but after flashing this over cm13 I can't see anything except google logo. Should I set my bootloader to the latest one?

6.0.1 (MTC20L) is what am using

I read the article along with the update, It's not quite fully functional, still quite a ways from being a working rom but he has shown that project treble does work and is somewhat viable. from looking at his screenshots the ril (sim stuff) is not working yet, I made some suggestions to him regarding his build that might fix that but he hasn't gotten back to me. Still not there yet but at least it shows that a generic AOSP Android can be installed and booted (at least the system and data images) by virtue of project treble. There are still a lot of things that are closed source relating to the hardware on our device and the SoC itself.

NFC not working, BT is wonky, FPS is not enabled, Keyboard is crashing when opening numbers/special chars, no HotSpot/Tethering, RIL does somewhat work but requires some more work on the actual device overlay.
But the essential things are working, Video Enc/Dec, Camera (Video, Photo), LEDs, Audio, HWC, vulkan, WiFi, BT (atleast its visible when i scan for it), power hal, maybe i forgot a few things ..
I've tested a self-compiled build on my H8 Pro, and thats the result, so i'd expect some similar situation for the Mate 9.

Did a build myself for the HiKey 960 reference board that uses the same SoC as the mate 9 and am doing a generic arm64 build right now, I'll be testing the both out when I get a chance. I think that I might have a little more luck with the HiKey build as it is the same SoC. It's a work in progress but project treble is showing some promise. I'm looking at making a flashable (in twrp) that will install the AOSP build (whichever one works)

You are very welcome, this all is a work in progress but from what I see so far project treble is going to make development easier in the future. I might try installing the boot image from my HiKey build to see how that works, it's the same SoC as our devices so it "should" boot, it's kernel version 4.9 which is the latest and supposedly greatest so we will see. If it doesn't boot I can always flash back the stock Oreo boot image.

I got a spare Mate 9 and can install and test stuff, happy to help

I'll keep that in mind

Yeah, the whole ASOP and treble thing is definitely a work in progress and it's going to take a little time to get that all working with the phone hardware properly but once it gets all figured out it is going to make updates easy and open the door to a lot of possibilities with custom ROMs

Is the kernel compiled too from AOSP, or is that pre-compiled already in a boot.img?

No, in order to use the AOSP build you have to install Oreo beforehand, there are beta builds available for a few of the mate 9 variants right now but the "official" Oreo updates should start rolling out sometime in December. I had downloaded and installed the beta for the US variant.

Nice share.:fingers-crossed:
Just tested playing around for 10 min. works fine.

I don't know if I missed something but I followed instructions to flash the rom but after waiting for 1 hour, I couldn't get the rom to boot. This also happens on the Pixel Experience rom you shared in your original post.
I flashed Lineage OS 15.1 after trying and that rom booted after 3 minutes, so I think the issue is in the roms.

Is always on display included?

Guys. Again from the same dev, nitrogen os.
Here's his work. I've not tested it on my device. If someone wants to test nitrogen os 8.1.0. U might need to be decrypted. Check if mist things work. Check if front camera works also. Gl hopes it works. Currently I don't have time to test it.

Honestly even 3 minutes is too long for a boot on this device. It's got 6 - 8 gigs of ddr4 ram with a snapdragon 835 - if the boot is taking longer than 1 minute I start to get worried about a bootloop. Usually it's a 15 - 30 second process on the first boot, and even shorter on reboots.
Am I crazy wrong about this? I swear my boots never take longer than a moment.

Format data in recovery then copy the ROM and Gapps to the device and flash. Should solve the issue. It did for me.
I sold my 5T. OnePlus are rumoured to go into administration soon over the company collecting and selling customer's data in China. Various members of the company have left, it was just this week that Adam Krisko from OnePlus left and he's one of the developers of Oxygen OS. It was a good wave for OnePlus.

Just wait a week. Don't use the developer preview. It's a really bad build and not stable at all.
The open beta is said to be coming out by the end of this month. Meaning it will be dropping this week unless there's been some sort of last minute critical bug found (doubtful).

Root in order to increase battery on Pixel 3A or 3A XL?

I am wondering if it makes sense to root the Pixel 3A XL in order to remove system apps and increase battery? Has anyone come out with a ROm that is mostly just stock, but with all of the junked removed? I don't really need root access like most people do. I just want to use the basic features of the phone "camera, internet browsing, email, finger print reader, etc and get the most battery life possible. I use an app like greenify to kill apps but that doesn't work on system apps. Is LineagOS this sort of thing?

A custom kernel will do far more for battery savings then rooting will. And there are several Roms in various states of completion in the works right now, including my own but not very many I would consider ready for prime time and none Ive seen yet that are what youre looking for. Stock AOSP is very different then stock Google and typically when a Rom dev goes that far they also add lots of other customizations which may or may not be to your liking.

There are a couple on here and the 3a XL forums. Im sure all the big dev teams have unofficial builds for both devices as well. As I build my own Rom I dont keep up on this too closely though.

Agree. Custom kernel might be all you need at first.
I switched to a custom kernel by flair2 for a different reason, as I was looking for LZMA compression support for TWRP, but I'm quite happy with the battery benefits that kernel brought to my Pixel 3a.

Are you running it on Android 9 or 10? I haven't updated to 10 because I have heard of issues with battery life after doing this update.

Battery on 10 is better than on Pie. I get roughly 10% better battery since updating. My guess is those experiencing it didnt clean flash 10 and just took the OTA.

Is there a guide that explains how to do that? I'm pretty inexperienced with all this.

A clean flash involves a factory reset. Be sure to back up any files to a different storage medium (PC, cloud, etc.) Once backed up, just use the factory image provided by Google.

The included .bat file (bat for windows, sh for Linux or Mac) is what you run. Be sure you get the latest fastboot drivers so you have no issues flashing in fastbootd. For future updates, just flash the stock boot image before taking the update or download the next month's image and delete the -w flag in the bat/sh file. That is the wipe switch.

Are you running it on Android 9 or 10? I haven't updated to 10 because I have heard of issues with battery life after doing this update.

I started using EX kernel on 9 to get permanent TWRP, but still using it now on 10, where we don't have TWRP. So I like that kernel a lot.
