unzip the cwm zip to your sd card (using file explorer or root explorer) and then use terminal program on aurora and type these commands
basically su gets superuser permission, then cd /sdcard changes the directory to the sd card where the install-recovery.sh file is. running sh install-recovery.sh will run the install-recovery script file which will copy the recovery img to the /data folder
then just shutdown the normal way and start up with back&power - you will now see the CWM console which has blue text and more options. if you are seeing green text, you dont have CWM installed
you can use CWM to install CWM images which you download from wherever of your choosing, these are zip files.
