The CyanogenMod (CM) team recently rolled out the first Milestone (M1) build of CyanogenMod 11 (CM11) ROM upfront for AOSP-based Google Nexus devices (Nexus 4, Nexus 5, Nexus 7 and Nexus 10) for the first time in the history of CyanogenMod development.
The new CM11 M1 update offers the latest Android 4.4 KitKat features with the added benefit of bug-less coding at the hardware level, as the firmware is released directly by Google. The lack of hardware bugs with Nexus devices reportedly paves the way for a stable user experience while running the new firmware.
The CM team recommends the use of ClockworkMod (CWM) recovery for installing the new CyanogenMod 11 M1 build on their devices, as TWRP recovery is known to have technical issues with the firmware installation.
Interested users can follow our step-by-step guide to install Android 4.4 KitKat via CM11 M1 ROM. IBTimes UK will not be held liable for any device damage during or after firmware installation. Users are advised to proceed at their own risk.
