Don’t like Samsung bloatware that come along with stock Samsung Galaxy S II firmware? Cognition S2 ROM is the one that you should try. Cognition S2 v1.31 is a custom ROM based on Android 2.3.4 Gingerbread (XXKG3). It is rooted, deodexed and zipaligned. And added lot of goodies like SIP over Wi-Fi and 3G, accurate battery mod, extended power options, disable battery full notification & vibration, specify default install location…
Cognition S2 v1.31 is using Ninphetamine 2.0.2 Kernel. Looking forward for next release which will be based on Android 2.3.5 Gingerbread (GRJ90).

i installed the cognition v1.42 without much problem. when new cognition v1.51 out, tried to install but cannot go into the external_sd folder to flash new rom. please help.
Did you wipe data and cache before install v1.51? I always prefer a fresh installation than upgrade. Please consult ROM chef if still cannot. ๐
can u help me to choose between villain & cognition.thx
Try them both. Then decide yourself. BTW, I am using LeoMar75 KI3 now. ๐
so,is ur leomar75 better than both of them…..
Don’t know. I did not try KI3 version of them. I picked LeoMar75 because it is clean and simple.
Hi..
I like your site, and specially i have bought a SII recently and want to root and play with it..
Can you please tell me, whatever we do.. i mean root etc, is it possible to bring the device back to stock so that the warranty etc remains ?? If yes, can you suggest a link ?
Thanks,
Ashu
