Update Galaxy Core Duos I8262 To Kit-Cat Android 4.4.2 Custom ROM

Last time we published an Article about Monster$ ROM based on Android 4.4.2 for Galaxy Core I8260, today we have another article related to the Dual SIM version of this Device Galaxy Core Duos I8262. Samsung probably won’t release the Official Kit-Kat Firmware for this device, but this Kit-Cat ROM, don’t mistake the name, will give you the exact Android 4.4.2 Experience on your Core Duos as it gives on Nexus 5. The list of the Features will be listed below and the list is so long that you will be satisfied with this ROM within a minute.

But why would anyone goes for a Custom ROM instead of staying on the Stock On, allow me to explain. “Stock and Official ROMs are good, but they are created with keeping in mind the demands of all,some wants performance and some wants speed, some wants looks, some wants features. Putting them all in one ROM can cause Lag, Performance issues and bugs. But Custom ROM in basically designed for either Looks or Performance and Custom ROM gives speed and great performance with Tweaks and System Tools.”
