Here's a detailed walkthrough on how to install CyanogenMod 9 for the Droid X
4. Download the Droid 2 Bootstrapper and ROM Manager from the Market. Flash ClockworkMod Recovery in ROM Manager and then Bootstrap Recovery in Droid 2 Bootstrapper.
5. Press Reboot Recovery in Droid 2 Bootstrapper to reboot to CWM Recovery.
I had to use the DROID 2 BOOTSRAPPER to get this to work on my Droid X. I tried using the droid x bootstrapper and it would reboot to the Red M then it would go to a black screen and sit there. Then I used the Droid 2 bootsrapper and I got it to work. Thanks!
