You will get bootloop if you install v2.0 of this ROM directly if you are using the external sd version of CWM (I believe most of you have installed this version). So install v1.2 first. Please refer to installation guide.
A few users of this ROM said once they installed v2.0 and reboot, all contacts stored in their SIM card were all erased! But I had never face this problem.
