C-ROM is available for most of the flagship devices and all of the other carrier bounded devices too.

But why would anyone go 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 want performance and some want speed, some want looks, some want features. Putting them altogether in one ROM can cause a Lag, Performance issues and bugs. But Custom ROM is basically designed for either Looks or Performance and Custom ROM gives speed and great performance with Tweaks and System Tools.”
