Good news if you’re rocking the Samsung Galaxy Mega 6.3 (GT-19200 or 19205): the CyanogenMod team has released a CM11 ROM based on Android 4.4 KitKat for your device.
This guide will walk you though the installation process. 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 Mega 6.3 (GT-19200 or 19205 model). Flashing this ROM onto any other device will most probably result in a bricked phone.
You must have your Galaxy Mega 6.3 rooted, with 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.

2) Using your USB cable, connect your Galaxy Mega 6.3 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 Mega 6.3 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 Mega 6.3 will officially be running Android 4.4 KitKat CM11 ROM. Kudos.
