How-To: Update A Galaxy Core I8260 To Android 4.4.2 Monster$ Custom ROM

Update A Galaxy Core I8260

Samsung released their Galaxy Core in 2013 running on 4.1.2 Jelly Bean.  It’s a pretty good device but, Samsung doesn’t seem to be planning to update it to Android 4.4.2 KitKat.

Since an official update seems out of the question, users of the Galaxy Core are having to turn to custom ROMs to update their devices.  In this guide, we’re going to show you how to update your Galaxy Core using Monster$ Android 4.4.2 custom ROM.
