Method 3 (easiest if you use a compatible version of CWR)*:
1. Download the patch
2. Boot into CWR (Clockwork Recovery)
3. Mount /system/ partition (on the main menu, select the "Mounts and storage" option, then "mount /system")
4. Flash the patch (on the main menu, select "Install zip from sdcard," then "choose zip from sdcard," and find the zip and select it)
5. Reboot the device
6. Review the NOTE section in Post #2.
*This was built for and works on Inspire 4G and DesireHD versions of Clockwork Recovery.
So does this method work with a Sensation, or might it cause problems? I only ask because you specifically mention it was built for another version of CWM.
