Yeah… I love custom firmware. Here is another custom ROM for Samsung Galaxy S II ~ LeoMar75 Revolution ROM. LeoMar75 Rom Revolution v2.5 is a fully ODEXED custom ROM. It is based on latest firmware XXKG6 Android 2.3.4 Gingerbread. Lot of features like mod-battery with incremental rate of 1%, JKAY Theme Settings, fully customizable Extended Power Menu, VOIP for Wi-Fi, BLN… Personally, I like the Revolution boot animation.
LeoMar75 Rom Revolution v2.5 is using angelom Thunderbolt Kernel 22. Try it out and do get more information at XDA.
