  • Based on the latest CyanogenMod 12 sources
  • Compiled with SaberMod 4.8 toolchain and O3 flags for maximum performance
  • Full F2FS support - no mount issues during ROM updates
  • Enabled Dex-Pre-optimisation for faster boot time
  • SELinux set to 'permissive' by default
  • Android default UID and GID for internal storage
    (No more write issues after formatting sdcard!)
  • Slim and fast user build
