I have a nexus S i9023. When I flash a ROM I do the following:
Factory reset, Wipe Cache, Wipe Dalvik then back button to main menu. I then press Install, select the appropriate zip file and then Flash Now. I then go back to the main menu. If I then press Install again to flash another zip file, the TeamWin curtain appears and the is drawn up as though the recovery had been rebooted. After this it all seems ok.
