I downloaded ROM to sd-ext.
Uninstalled Bionic Bootstrap
Installed latest safe-strap from OP
Rebooted and hit menu @ safe-strap screen (within 10 sec.)
Used safe-strap to back up (better safe than sorry)
Clicked safe menu and toggled safe mode
Once in safe mode, wipe data/factory reset, then wipe cache, go to mounts and format /system, then wiped Dalvik
(sd-ext error when wiping Dalvik is ok)
Then, install .zip from sd card and select ROM.
Reboot, and behold the glory of ICS!
When you are done playing, reboot and get back into safe-strap and toggle to unsafe, reboot. You're back to your normal ROM.
