CyanogenMod says its modifications improve the performance and reliability against official versions of the software. According to its developers and because its development model of open source (which makes any individual can verify the authenticity of this statement), CyanogenMod does not contain spyware or bloatware
Shortly after the introduction of the HTC Dream terminal in September 2008, the community of Android developers found a method to obtain superuser (root) on the Linux subsystem Android (procedure known as ‘I rooted’ device). This discovery, combined with the open source nature of Android, allowed to modify the original firmware and re-installed on the phone at will.

The latest version of CyanogenMod is based on Android 6.0.1 (Marshmallow). Lots of modified code are written primarily by Cyanogen (Steve Kondik), but includes contributions from the developer community XDA Developers5 (such as improved browser) and other contributors to the project.

Cyanogen also maintains the image restoration used in combination with CyanogenMod. It provides a special boot mode that is used to back up and restore the device software, or repair and upgrade the firmware. It is an essential integral methods rooteado “one click” available for most current Android devices.

The CyanogenMod Updater application allowed users to receive notifications of updates, download and install on your terminal. It was available through the Google application store (Google Play Store) and was developed by Garok89 (Ross McAusland) and Firefart (Christian Mehlmauer) of the XDA Developers community, based on JF-Updater Sergi Velez. Now is the Manager10 ROM application that best fulfills these tasks. The application, developed by Kush (Koushik Dutta) is also available in the store, and is integrated into CyanogenMod.
