If you've successfully used this package to root your phone - and this is the ONLY
package you should ever use to get root and CWM - you will have a purple recovery. If you have anything else, you've done it wrong, and need to carefully follow the instructions in the first post.
Once you're back on stock, do exactly that. You will be able to boot into CWM as listed once you have. Once there, you can flash what you like.
