OnePlus One users are yet to receive any official Lollipop update from OEM or Google, while the industrious CyanogenMod team has just unleashed the latest custom Android 5.0.2 update via CyanogenMod 12 (CM12) Nightly ROM.

The new CM12 Nightly build brings tons of custom Lollipop features based on the original Android Open Source Project (AOSP), which can be installed on your OnePlus One using any custom recovery tool such as ClockworkMod (CWM) or TWRP.

The CM12 Nightly ROM offers a fast and smooth Android experience, besides introducing a handful of new features and enhancements that are not part of the OEM or stock Android versions.

Though the CM12 Nightly ROM is still in its beta stage, it comes in a highly-stable release.

Some of the noteworthy features ported into the CM12 Nightly Lollipop ROM for OnePlus One are listed below:

  • Vibrator Intensity
  • On-screen/Capacitive Buttons options
  • Button Options (CM tweaks)
  • Notification Light (LED) options
  • Double Tap to Sleep/Wake - Status Bar Sleep+ Wake screen
  • Ambient display
  • Accidental Wake-up
  • Color Enhancement
  • Sunlight enhancement (On by default cannot turn off..)
  • Privacy Guard
  • Blacklist
  • Status Bar Options (CM tweaks e.g. quick pulldown)

  • The instructions given in this guide are meant for the European variant of OnePlus One only. Verify device model number by navigating to Settings > About Phone.
  • Ensure the phone has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing the ROM.
  • Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup. In Recovery, choose Backup and Restore and tap Backup.
  • Verify correct USB drivers for the phone are installed on the computer (download OnePlus One USB drivers).
  • Enable USB Debugging mode via Settings > Developer Options (if running Android 4.0 or above) or Settings > Applications > Development (if running Android 2.3 or earlier).
