lol not really
what you have to do in clockwork is
1. navigate down to -backup and restore
2. -backup. when thats done,
3. - wipe data/factory reset
4. -wipe cache partition
5. -install zip from sdcard
6. -choose zip from sdcard
7. navigate using the volume rocker down to where the nightly zip file is and and click on it using the camera button
8. when thats done installingm, navigate to the where the gaps zip is and install that too
9. when thats done press reboot, when it finally comes up you log into google account restore all your apps and contacts... etc like when you first got the phone.
also DO NOT USE droid 2 bootstrapper in cyanogenmod7 to get into recovery, hold the power button and press reboot, a sub menu should pop up asking if you want to reboot into bootloader or recovery(clockwork), if you want to go back to what you had before you flashed cm7 just reboot into recovery and navigate to -backup and restore, instead of pressing backup press restore and youll be able to choose which file to restore to(if this is your first time using clockwork theyll just be one) and click on that, it will automatically start restoring and you should be fine.
if you somehow manage to get yourself into a bootloop or stuck in the bootloader with a code corrupt error just say so and i can give you a tutorial on how to sbf using linux or RSD lite.
