We already published a detailed full root method for the Samsung Galaxy S2 using Odin. We also 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 complete set of guides for all other custom ROM installations as well as other tips&tricks for SGS2!
Now is the time to cover another promising custom ROM named Cognition S2 that has been released recently by the XDA forum member designgears. This ROM as with many other recently released custom ROMs for the Samsung Galaxy S2 integrates a number desirable tweaks such as disable battery full notification/vibration, extended power options, no ascending ringtone, updated system apps, hacked camera (for high bitrate HD recording), clockworkmod recovery 18.104.22.168 and is of course pre-rooted.

I highly recommend flashing the full rom! (updates can be unpredictable)
(If you have problems with the update version, flash the full rom instead)
BACKUP BACKUP BACKUP!!
Download the rom zip from below (don’t rename it!)
Put the downloaded zip file on your internal sdcard
Reboot into ClockworkMod Recovery (don’t do this from rom manager, it won’t work)
Select Install zip from sdcard
Select Browse for zip on sdcard
Select the zip file you put on your sdcard above
(Let if flash)
Don’t forget that it will wipe the exiting date on your phone! So, back it up as mentioned above. Don’t forget to have a look at the guide: Install ClockworkMod 126.96.36.199 (CWM) Recovery For Samsung Galaxy S2 (II) as developer recommends to flash this from CWM.
