Install CM11 on Galaxy Mega and Update to Android 4.4 Firmware

CM11 is a powerful custom ROM that is based on stock Android 4.4 KitKat firmware. Now, considering that CyanogenMod is the most popular and appreciated custom update probably you will want to try the same on your Samsung Galaxy Mega. If that’s true, then you can safely use this step by step guide because during the following guidelines we will be checking on how to install CM11 on Galaxy Mega and update to Android 4.4 KitKait OS.

As I have already stated, CM 11 is based on Android 4.4. But, this isn’t an official version of the KitKat platform that is being available for your Galaxy Mega. CM 11 has nothing to do with Samsung or with Google as the firmware is being developed by third party devs. That’s why you need to consider this update a free aftermarket distribution of Android 4.4 that can be flashed on your Samsung Galaxy Mega. Because of that CM11 will bring both stock and extra (that cannot be found on the default variant of Android OS) features, capabilities and apps.

Also, CM 11 will be bringing its own looks and user interface which means that on your Mega you won’t be able to enjoy the pure Android 4.4 KitKat experience. The firmware is optimized especially for your phone so the software will smoothly run on your smartphone. According to those who have already tested the CM11 platform on the Galaxy Mega, the system works without errors or lags and there aren’t major bugs or issues included. The update can be safely applied for a daily use, not to mention that you will soon be prompted with a new and more stable version of the CM 11 firmware.

With CM 11 you can power up the performances of your handset and you can easily customize and optimize the battery life, the user interface, the speeds and the web browsing experience. You will be able to remove in built programs, the bloatware and you will also be able to overclock / undervolt your Android device. But for being able to do that first you will have to complete this tutorial. The installation procedure is not hard to complete though you do have to take care of the pre requisites first – just take a look on the list from below and complete the indications explained there.

  • First of all you need to unlock your device. For being able to do that you have to learn how to easily root the Galaxy Mega.
  • With root access ensured, you can then safely install a custom recovery image on your phone.
  • I recommend you to use CWM or TWRP recovery because the devs had tested the CM11 OS only with the mentioned apps.
  • CWM recovery is one of the most used and appreciated custom recovery while TWRP recovery is the touch version of the first app.
  • Do note that a custom recovery image can be flashed only on a rooted system.
  • When gaining root access, your Samsung Galaxy Mega warranty will get void – this is happening because the binary flash counter will be increased (gaining root access, and basically all the other operations, including the present one, aren’t official).
  • So, for restoring the warranty you will have to reset the flash counter; you can do that by revoking the root access: downgrade to stock Jelly Bean OS or wait for the Android 4.4 OTA update to be released and rolled out by Samsung for your Galaxy Mega.
  • Backup the data which you have saved on the internal storage memory. As you will see during the proper installation procedure, a wipe will be required. When wiping the system, your data might be erased. Because of that you need to save everything that’s important for you.
  • Remember that CWM recovery is installed; use the same for saving the current ROM – if CM 11 isn’t what you want, then you can easily restore to your old firmware.
  • Also, consider in backing up the Galaxy Mega EFS folder before going any further.
  • Then, make sure that you can use a notebook, or a computer along with your smartphone and with its official USB cable.
  • This is a manual update procedure so the required files will have to be downloaded manually. Because of that and for avoiding the unpleasant situations from happening, before starting the steps from below deactivate the security protection that is featured on your computer and on your Galaxy Mega.
  • Of course, you will have to connect your phone with your computer at some point for being able to transfer the downloaded files from the PC to your phone. Because of that from “menu – settings – developer options” you need to enable USB debugging on your Mega.
  • A manual update process means a few minutes of installation procedure. So, before applying something you need to check the battery status of your device: if there is less than 50% battery power left, you have to plug in the charger; else you can skip this step.
  • It is important to complete this guide only if you have the Samsung Galaxy Mega model number GT-I9200/GT-I9205; the CM11 Android 4.4 custom ROM is compatible only with the mentioned device.
