Step 2: Root your Nexus S or Galaxy S, you might have to Google around for the latter. It’s an easy task but with quite a few steps. When your devices are rooted, return to the guide.

Step 4: Simply Back up your data. While still in ROM Manager, scroll down and select “Backup Current ROM”. Once completed the backup can be found in your SD card under ‘clockworkmod’ directory. Better to transfer this backed up data to your computer in case you need to restore it to an earlier state.

Step 6: Now, Select “Wipe Data and Cache”.

Step 7: Select “Wipe Dalvik Cache”.

You phone will now automatically restart,. After it reboots, you’ll be welcomed by the Ice Cream Sandwich set up screen. Keep in mind, since this particular build is re-rooted, you’ll have to restore from backup if you are wishing to revert to the Gingerbread version. Currently, the build seems to be working perfectly. via
