nature of the Android operating system, allowed the phone's stock firmware to be modified and re-installed onto the phone. In the following years, several modified firmware releases for mobile devices were developed and distributed by Android enthusiasts. One, maintained by a developer named Roman Birg of AOKP, quickly became popular among several high-end Android mobile owners. AOKP started in November 2011 and quickly grew in popularity, forming a small community of developers called the AOKP Team (also known as "Team Kang"). Within a few months, the number of devices and features supported by AOKP escalated, and AOKP quickly became the second most popular Android firmware distributions, CyanogenMod being the first.

Contributions may be tested by anyone, voted up or down by registered users, and ultimately accepted into the code by AOKP developers. In early 2020 AOKP Developers posted a blog outlining parity with LineageOS upstream. "''Device support will be a bit different this time around. We can support any device that is getting Lineage 16.0 builds. We just need a maintainer to test builds and maintain a forum thread.''" 2011 * AOKP Ice Cream Sandwich (ICS) Android 4.0.X 2012 * AOKP Jelly Bean (JB) Android 4.1.X 2013 * AOKP Jelly Bean (JB-MR1) Android 4.2.X * AOKP Jelly Bean (JB) Android 4.3.X 2014 * AOKP KitKat Android 4.4.X 2014 * AOKP Lollipop Android 5.0.x 2015 * AOKP Marshmallow Android 6.0.1 2016 * AOKP Nougat Android 7.0 * AOKP Nougat Android 7.1.x 2017 * AOKP Oreo Android 8.0 * AOKP Oreo Android 8.1 2020 * AOKP Pie Android 9.0
