It seems the real custom development on the HTC One X has now begun in full force. Two major custom ROMs have come out for it in a short span of time. MIUI 4 is now available for the One X, bringing you its unique UI (which would look beautiful on the Super LCD2 screen on the One X) and features such as an intuitive status bar, inbuilt themes support with thousands of fan made themes available, improved performance, and more.

The ROM is in the beta stages, but almost everything works so it’s perfectly suitable for everyday use. There might be a few Chinese text here and there in the ROM as it has been translated to English, but expect that to be fixed in future releases.

Read on to find out how you can install MIUI ROM on your HTC One X.
