I want to install CyanogenMod on my Samsumg Galaxy S II. If I install ClockworkMod I think I will void the warranty provided by Samsung.

Must I install ClockworkMod or can I just install CyanogenMod?

Two things are important here:

1.) Even if you wouldn't install ClockworkMod, you'd lose your warranty since you replaced the pre-loaded operating system with unsupported one.

2.) ClockworkMod (or any other alternative recovery) is what actually installs CyanogenMod on your phone so it is required.

In short: Replacing your phone OS with Cyanogen will void your warranty in any case. You'll need some way of installing CM and Clockwork is probably the easiest around.

ClockModWork only works with Cyanogen images? – Ed Pichler May 20 '12 at 16:16
Nope, pretty much all 3rd party ROMs prefer ClockWork Recovery as their way of installation - just point it to the .zip file. – Mavrik May 22 '12 at 9:19
Well, I know ClockworkMod is installed prior to CM, and remains on device with CM, but I wonder if it is possible to install CM instead of ClockworkMod, to boot CM directly? I know it's more convenient to have CWR installed, just I have a security requirement to disable CWR boot – Mixaz Apr 2 '15 at 21:23
