Looking for a good Android 5.1 Lollipop ROM for your Galaxy S2 GT-i9100?
Check out the CM12.1S ROM, which is a hybrid of CM12S ROM from OnePlus One and latest Android 5.1.
This ROM features latest CyanogenMod CM12.1 Android 5.1 features along with OnePlus One camera, AudioFX, Screencast (screen recording app), and Hexo theme. I’ve tried many of the latest CM12.1 and Android 5.1/5.1.1 ROMs in the past week but found this ROM to be most stable with everything working out of the box except Netflix video playback. Also, if you want to know about all of the latest CM12.1 ROM features, check out this video.
Overall, this is a fantastic Lollipop ROM for those of you who want to get your feet wet with Lollipop so definitely check it out this week(end). I should have an update real soon though on a stable Android 5.1.1 custom ROM.
Download Android 5.1 Gapps (DO NOT USE older Gapp as you will FC!!!)
For installation, please follow How to Install Android Lollipop ROM on Galaxy S2!
To install, reboot into recovery, make backup ROM, wipe data/factory reset, install ROM, install Gapps, install SuperSU and reboot. (If for some reason you end up in a bootloop, reboot into recovery, go to Advanced Wipe for TWRP or Mounts & Storage for CWM, format/wipe /system, then re-install ROM.)
