CBP determines whether someone can be admitted. Even with valid ETSA a person can be denied entry on the VWP. Your friend's overstay effectively cancelled her ERSA by operation of law. To return to the United States, your friend will need to apply for a visa at the U.S. Embassy. She may also need permission to reapply for admission. It will depend upon what exactly transpired during her last entry. Your friend should have an attorney review any paperwork she was given by CBP.
