Android Lollipop on the Samsung Galaxy S2
You can still get Lollipop on your Samsung Galaxy S2, despite Samsung leaving it on Android Jelly Bean 4.1.2, thanks to the selfless work of the Android developer community. Omni, a community-based project, released its OmniROM 5.1.1 in November 2014.
The ROM remains in beta, and hasn't been updated since June 2015, so bugs are to be expected. If you desire a modern twist for your trusty S2, however, give it a go.
The files you need, and instructions on how to use them, along with known bugs, can all be found over at the XDA forums. One word of warning: be sure to back up your device before taking any steps towards installing the ROM.
