VillainROM is very new to me that coming from HTC HD2. However, it should not be unfamiliar with most others because VillainROM is one of the most popular custom ROM for Samsung Galaxy S II. Therefore, I picked VillainROM as my first custom CWM firmware to try. What makes VillainROM special? Based on VillainROM v2.4.2, it is fully deodexed. So you can apply custom theme but stock browser will lag. Fully resigned, but with Samsung apps left using stock signatures. You still have the stock TouchWiz from Samsung. And rest assures that it is rooted and added with Busybox and Superuser. Ninphetamine kernel that supports BLN is included too.
