How to install Android 7.0 Nougat on Galaxy Mega 6.3 I9200/I9205

Origin of Samsung’s Galaxy Mega series dates back in the year 2013. Samsung released two devices, the Galaxy Mega 5.8 and Galaxy Mega 6.3. These were not the mainstream flagship devices, however, they did quiet well in terms of sales. Galaxy Mega 6.3, the bigger variant carried a 6.3-inch SC-LCD capacitive touchscreen display. It was powered up with Qualcomm Snapdragon 400 Dual-Core CPU accompanied by Adreno 305 GPU. Storage options were 8/16 GB and RAM was 1.5 GB. Galaxy Mega had an external SD card slot as well. 8MP shooter at the back and 1.9MP shooter was fixed on the front. Galaxy Mega 6.3 ran on Android 4.2.2 Jelly Bean out of the box and its updates ended at Android 4.4.2 KitKat. Since then, the device has been neglected completely by Samsung in terms of software updates.samsung-galaxy-mega-6-3-front

Since the discontinuation of Galaxy Mega’s official software updates, the only updates that the Galaxy Mega is relying on are custom ROMs. Earlier, we had a chance to taste Android Lollipop on the Galaxy Mega. We also had a chance to run the Android Marshmallow on Galaxy Mega by means of custom ROM. Now we have the Android 7.0 Nougat out for the Galaxy Mega 6.3 as well.

Android 7.0 Nougat for the Galaxy Mega 6.3 I9200 and the LTE variant I9205 comes out based on an unofficial build of CyanogenMod 14. Luckily, the most common features like Calls, sending text messages, mobile data, Bluetooth, Audio, Camera and Wifi are found working on this ROM. The ROM is in its early development stages and it’s supposed to carry a few bugs here and there. But if you are a power Android user, the bugs really shouldn’t matter and the installation should go smooth for you.

In the following post, we will show you a very easy method to install Android 7.0 Nougat on Galaxy Mega 6.3 I9200/I9205 via CM 14 custom ROM. To make sure that nothing goes out of the way, follow the instructions carefully.
