Since the release of the Samsung Galaxy S2, we published a number of rooting and ROM customization articles including (but not limited to) detailed full root method for the Samsung Galaxy S2 using Odin. Then we brought you a guide on how to install the first ever custom ROM for your shiny new SGS2 in the form of VillainROM (v1.0)! Which was a pre-rooted ROM optimized for performance and with much greater scope for any upcoming tweaks. Later we presented a guide for installation for a recently released high performance custom ROM called Lightening Rom XWKE7 for your Samsung Galaxy S2 (SII). Installation for Lite’ning Rom v1.4 For Samsung Galaxy S2 (SII) with Extended Power Menu, CF-Root 3.8 kernel, No Ascending Ringtone was covered here. Of course, you can always head to the Android Rooting section on our website to get the full scoop on all custom ROM installation guides as well as other tips&tricks for Samsung Galaxy S2 (SII)!

We always try to bring the most promising and powerful custom ROMs available for our users. Now is the time for another promising ROM with a lot of useful features missing from the stock Samsung Gingerbread ROM installed on Galaxy S2 (II). This ROM as with many other recently released custom ROMs for the Samsung Galaxy S2 integrates a number highly desirable tweaks such as disable battery full notification/vibration, extended power options, no ascending ringtone, updated system apps (including new Market version), hacked camera apk (for high bitrate HD recording), clockworkmod recovery (CWM) and is of course pre-rooted. It also installs some other applications such as FileExpert, HomeSwitcher, Skyfire, Open VPN Settings UI, GScript Lite. This custom ROM also supports overclocking up to 1504 Mhz. Removes Wi-Fi sharing to save battery life. Theme is of blackish flavor. Another novelty is the inclusion of the new lockscreen functions which seem very useful (direct launch of the camera application or the music player etc.).

Here are all the features and tweaks enabled by the LeoMar75 Rom Revolution according to the developer:

Based on the latest official firmware XXKG1 Gingerbread 2.3.4
