Hi all,

This is an unofficial Pie build for the Galaxy S2 (i9100) based on LineageOS 16.0.

Yes Pie on our ancient Galaxy S2. I had it working in September 2018 but waited after I had Autosleep ported to our kernel. The biggest issues before I started porting Pie was the Display stuff. We needed at least HWC 1.3 and we had our old HWC 1.0. Surfaceflinger removed all legacy stuff, so how to upgrade to a new HWC??? I got no knowledge how that works.... Then I remembered that @Fourkbomb was rebasing the kernel for i9300 and was working on HWC. He was working on HWC 1.4, so I tried to port those drivers in our kernel with success! Got display running! After that I fixed a minor thing in system/vold, adding patches we already have in LOS 15.1 and after 3 weeks I got it booting! But batterylife was horrible due lack of AutoSleep. So I ported AutoSleep first to our stable unofficial LOS 15.1 kernel. And now that works, lets publish this first unofficial version of Pie on our S2!

Update 2-2-2019:

I decided to switch to emulated storage. The storage issues are probably because of the legacy partitioning. The crash of the Files-app crashes because of this. The only downside I see is that you need to repit if you want to go back to stock or CM-15.1 or less. We need to use repit anyway for the 1.5GB System partition, so why not? Maybe because you are using LOS 16.0 allready and have some stuff on sdcard0 (the phone' s internal SDCard). I developed 2 years a ago a migration recovery but lost focus. Before you install LOS 16.0 Build#7 and higher, please follow the following instruction:

Upgrade from Build 7-13 to Build #14 and higher

Flash i9100-LOS-16.0-Emulated-Storage-TWRP-3.3.1-1.img and reboot recovery. In TWRP-3.3.1-1 you will then be able to (dirty) flash

lineage-16.0-20190707-UNOFFICIAL-i9100.zip

Upgrade from Samsung stock ROM to Build #14 and higher using ODIN 3.07

Copy lineage-16.0-20190707-UNOFFICIAL-i9100.zip to your Micro SD-card before flashing.
