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.
