A new Android 5.1 Lollipop custom firmware has been made available to the Galaxy Note 2 (3G) GT-N7100 model.

Though there are numerous speculations of Samsung planning to release the new 5.0 Lollipop OS update to the 2012 flagship phablet Galaxy Note 2, we believe this might not turn true as Galaxy Note 2 is more than two years old, well past the 18-month OS update service contract, which makes the company no more obligated to release the update to the phone.

Impatient Galaxy Note 2 owners can experience the candy-flavoured Google mobile OS v5.0 by installing new CyanogenMod software on your device.

This new custom firmware is based on AOSP (Android Open Source Project) v5.1 Lollipop and is said to bring customisation options to boost device performance, new visual interface, shortcut for easy access to key apps and loads of personalisation options such as:

  • OpenGL (CPU rendering)
  • MALI blobs (GPU rendering)
  • HWComposer and MALI R3P2 drivers
  • Rotation
  • Camera
  • Wi-Fi
  • Bluetooth
  • NFC (Android Beam)
  • Sensors (ALL!)
  • Internal / External SD Card
  • Vibration
  • Home Button wake
  • Simlock
  • RIL
  • GPS
  • Signal Icon
  • Soft Keyboard on first boot
  • Mouse pointer
  • H/W Video playback
  • Performance tweaks and many more improvements to enhance user-experience

This new custom ROM is CyanogenMod CM12 series is developed by a senior XDA Developer forum member going by the moniker, Ivan_Meler. But we like to remind that this CM12.1 version is experimental software, so some issues are yet to be fixed. We advise our readers go through the whole tutorial article first before going ahead with the custom ROM installation
