Hi all,
This is a WIP Oreo build for the Galaxy S2 (i9100). Almost everything is working
I'm currently using TWRP 3.0.2 on my dev-phone to install the ROM. Other versions of TWRP I haven't tried. I had a hard time to identify the stability issues and issues with RIL because of lack of debug info. Thanks to @ChronoMonochrome for giving key information to troubleshoot these issues! The stability issues are fixed by several workarounds. (Java NullPointerExceptions are causing native crashes even when they are within try-catch block).
Known issues:
Offline charger not working! Don't drain your phone.
Battery drain, but device do deep sleep
Video recording and playback (partially) not working
No HW video en-/decoding
YouTube just stops after about 10 minutes (no forced closed)
No recent apps behind home button Longpress left touch button.
Can't install su-addon of LineageOS
SuperSU is working but after dirty flash new build causes bootloops
LOS SU is included in these builds.
Lineage PowerHAL needs HIDL implementation for powersaving support
No V-Sync
Distortion when making screenshot and rotation animation
Camera rotation not working (Accelerometer issues)
It sometimes works after standby/wakeup sequence within 5 seconds with camera app still active.
Still batterydrain (Kernel?/wakelock?/GAPPS?)
Battery drain is caused by GAPPS. Installing it and registering an account eats 10% per hour. ROM is deep sleeping fine.
Battery drain is caused by Wifi-scanning. After installing GAPPS the Wifi scanning (and Bluetooth) options are enabled by default. Because of this Wifi is ALWAYS active nevertheless the global Wifi-settings! This behavior doesn't exist in LOS-14.1 (Wifi always active with Wifi scanning enabled)
After a day, some apps are crashing. (Like Cool Tool, WebView (standard browser))
This has something to do with ART. Please correct my findings. I don't know how ART works exactly.
When the app gets optimized by dex2oat and ART is executing it not using JIT, the app crashes when an Null pointer dereference occur.
This occurs after 4 -6 hours when the device is idle on the charger. This even occurs when the java-code is catching the exception.
I guess I miss some kernel commits but I don't know where to look... Help!
Temporary workaround is clearing Dalvik-cache via recovery.
For WebView related crashes, you can install Chrome and use this as your WebView-implementation under Developer Options.
We limit ART's compile filter to 'quicken'. ' speed' and 'speed-profile' doesn't work properly on our device.
Enable GO (Low RAM) configuration
I created separate builds for GO until I found out there is a generic solution for this.
You can easily switch between editions by flashing the zip via recovery. Just ignore the TWRP-error.
I didn't investigate its cause but it works. Credits goes to @AdrianDC for this MOD.

Overall state: Stable-ish
Android build: 8.1.0-r47
Changes:
- Updated Lineage-sources

Build #16 2018-10-4
Overall state: Stable-ish
Android build: 8.1.0-r46
I marked the previous build as stable since I was using it for months as daily drive with no issues except the Wifi battery drain when Wi-Fi scanning is active. In this build the kernel has been updated with AutoSleep-feature so I expect a change in battery usage. (Wakelock Detector now reports our wakelocks.) I just finished porting the feature and updating all drivers so I can't tell we actually have improvements. Please test and report.
Changes:
- Updated Lineage-sources
- Deprecated early suspend. We have autosleep in our kernel!
Known issues & workaround:
- Battery drain caused by Wifi scanning which keeps Wifi always active.
Turn Wi-Fi Scanning off here: Settings -> Security & Privacy -> Location -> Scanning ->Wi-Fi scanning

Build #10 2018-5-1
Overall state: Stable-ish
Android build: 8.1.0-r20
DON'T INSTALL THIS ROM ON YOUR DAILY DRIVE PHONE.
Changes:
* Significant Motion sensor added (Experimental for Doze)

And I noticed out of memory issues, hangs and softboots.
* Implemented Lineage PowerHAL HIDL implementation for powersaving support.
* Enabled touchbutton brightness-control.
Still working on:
* Accelerometer/rotation issues
* IMEI - IMEI RIL-requests are depricated. I'm trying to shim this.
* Graphical glitches - Probably because of issues with backing store not supported in libMali.so.
* Shimming exynos4 specific things.
* Still in doubt if GPS fix is actually improved....

Official Open GApps 8.1
Download Open GApps recommended by the Lineage OS team
Installation in TWRP-3.1.0-0 was successful.
Upd.
My first time too was not loaded.
I did all the Wipe and uploaded in 5 minutes.
The screenshots are done, but the screenshot's image is very bad, like on the old TV, where the channel constantly gets off and does not see anything, so @rINanDO posted such an image, not a screenshot.
Yes, almost nothing works, but the phone works quickly, without a cellular connection, you can check and solve the problems, but my s2 is the main phone.

It looks pretty cool even tho with bugs. Hope it comes out soon without bugs.... Thank you!

---

Blood pressure dropped a bit when I saw 'Android O' even in alpha phase!
I'll try right now!
---------- Post added at 02:08 AM ---------- Previous post was at 01:52 AM ----------
How can I help besides reporting the bugs?
EDIT: I tried to install the trial version of Oreo lineage with TWRP versions 3.02-1 and 3.1.0. Unsuccessfully. It is only in part 'Patching system image unconditionally'. 10 minutes later it stays the same and the CPU of the cell phone goes to 67 degrees. Exit the screen only if you remove the battery.
I also tried the recent kernel dorimanx and nothing happened.
I'll wait for the next test build =)

---

I tried to flash the build with latest twrp but doesn't boot

---

How is battery life?

---

* buying more popcorns *

---

Hehehe great! Work hard for a full supported port!

---

On my device It boot's up, but the colors are inverted in some way, the blue on the logo is a green, the entire system get's green for some reason

Yeah, exactly like this, to me that was green hehe

Do you make any selinux patches update in tree @rINanDO

No, not yet. Need to work on other stuff first.

I am also having the green colour issue. I think the home button issue can be fixed by editing keylayout files

The problem is the code is broken, and those keylayout files are thereby temporary excluded. Otherwise build will fail. It will be fixed, but we need to be patient.

Hi @rINanDO
I tested your 'very very WIP' ROM, and I can say that as others it booted successfully, 2hours after I flashed it. Sadly I got enough memory but your provided Gapps couldn't install cause there was a sudden memory leak,nevermind, as others, the colors are inverted, but, for a WIP ROM, It was good to see it booted on my i9100, what was the new thing on the main screen, is it a kind of app drawer?
Anyway thanks for all the hard work your puting in this project, I've been trying your unofficial Lineage ROM since the very first one and am still impressed, an Oreo build for i9100, and you are always on the go, thanks for that, be sure that I'll check your thread as soon as possible, I sendyou all the possible luck I could.
Cheers!
Edit: tested over Isorec TWRP 3.1.0.0 as it is the one I installed previously on my i9100, good night

Hi to everyone,
I installed this wip rom from twrp 3.0.2.1 without gapps and the boot is OK but the problem is that the wifi does not work and there is no configured baseband of it being a bit closed ... Also there are random restarts and when it happens it stays in bootloop .. . To start it then a factory reset is needed. I then tried loading gapps pico 170902...boot is ok but at startup there are continuous stop processes and everything turns instabile and unusable.
I'm looking forward to release and thank you for keeping S2 alive!!!
Regards.

To fix the display colors inverted, you need to apply patch . You might also want to bring a legacy audiopolicy back: https://github.com/UltimateROM/android_frameworks_av/commits/cm-15.0 .
In my case audio is working now on Galaxy Ace 2.
Btw, any ideas on how to bring up RIL to work? I've started to work on frameworks/opt/telephony, but I've a kind a feeling I'm working not in a right direction as I can't seem to find a similar works for this repository. Just wondering how some devices' RIL works without using a custom RIL class.
