Samsung Galaxy Grand Duos I9082 or I9082L can now be updated to Android 5.0 Lollipop software unofficially using the famous custom ROM, CyanogenMod 12 that's built based on the Google's latest mobile OS. Looks like the CyanogenMod (CM) is a favorite code source among the third-party developers to be used to create modified versions of Lollipop. As we have seen previously that lines of Galaxy flagships were served by CM12 ROM.

Galaxy Grand Duos is indeed a good phone comes with a remarkable bunch of features like TFT capacitive touchscreen, 16M colors, powered with Dual-core 1.2 GHz Cortex-A9 along with Broadcom VideoCore IV as its GPU. Thus having a Lollipop running on the device will make it more smart and strong.

If you are thinking to update your Galaxy Grand Duos software, then it's the right time to do so. A recognized member of XDA developers had shown his ability to deliver CM12 based Android 5.0 software to us and invite anyone with the device in hand to give it a try.

However you should also know what things will not work after CM12 ROM installed.

  • FM Radio does not work
  • Sometimes wake up causes music stutter
  • Wi-Fi HAL (i.e. Scanning MAC Address Randomization) not implemented
  • Camera app sometimes crash on close
  • Unable to un-pin screen without rebooting
  • Some users have reported issues with call audio (see FAQ for a possible fix)
  • Some users reported random low video recording volume
  • Launcher shortcut of apps moved to SD might disappear (this is a launcher issue and I'm not planning to fix it. You may be able to switch to a third-party launcher which does not have this problem.)
  • Swipe-typing and face unlock are NOT ROM issues. They need the proper libraries from Google Apps.
  • Does not work on 4.1 stock ROM's bootloader, please upgrade to 4.2 before flashing

Read these please!

  • Installing this ROM will void your warranty.
  • Whatever will happen --whether is good or bad -- as the result for following the guides is entirely your responsible.
  • Make sure your battery power is sufficient to perform the flashing process.
  • Enable your Android USB debugging mode.
