Installing Android 4.4.1 CM11 ROM On Galaxy Grand Duos

If you own the Samsung Galaxy Grand Duos and wonder how come your phone looks so much like the Galaxy S3, but doesn’t get nearly as much attention by the CyanogenMod team, you’ll be happy to learn that you haven’t been forgotten and an unofficial CM11 ROM has been released for your device by XDA developer, pawitp.    

This guide will walk you though the installation process for CM11 on the Galaxy Grand Duos bearing the model number I9082. As always, DroidReport assumes no liability for the firmware installation. Proceed with caution.

Before Getting Started

Do not use this guide for any device other than the Galaxy Grand Duos (I9082 model). Flashing this ROM onto any other device will most probably result in a bricked phone.

You must have your Galaxy Grand Duos rooted, with a recovery utility like ClockworkMod installed. As always, you want to backup your device and charge it to at least 80 percent.

Finally, enable USB Debugging mode by navigating to Settings -> Developer Options.

Updating Galaxy Grand Duos to Android KitKat 4.4.1 via CM11 ROM

1) Download the Android 4.4.1 KitKat CM11 ROM and the Google Apps package, which can be found here and here.

2) Using your USB cable, connect your Galaxy Grand Duos to your computer.

3) Copy CM11 custom ROM and the Google Apps package to the root folder of your handset’s SD card. Do not extract either.

4) Boot your phone into Recovery mode by pressing the Volume Up, Home and Power buttons simultaneously until you see a Galaxy Grand Duos logo, then release all three to enter recovery mode.

5) Perform a factory reset by selecting “Wipe data/Factory reset.”

6) In CWM recovery, navigate to “Format system” in the Mounts and Storage submenu, and then press “Yes.” Next, navigate to the Advanced submenu and select “Wipe Dalvik Cache.” Select “Yes” when prompted.

7) Navigate to “Install Zip from SD card” and select the ROM downloaded earlier. After the ROM is installed, repeat this step to install Google Apps.

8) After the installation is complete, press “Go back” and then select “Reboot system now” to restart your phone. This may take some time.

9) After restarting, your Galaxy Grand Duos will be running Android 4.4.1 KitKat CM11 ROM. Kudos.
