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
  • No V-Sync
  • Distortion when making screenshot and rotation animation
  • 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.

Download Gapps for Lineage OS – Android 8.0, 7.x, 6.x [All Versions] [Updated Daily]
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.

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 =)

True, I didn't noticed that at first.
