Qasim bin Muhammad (may Allah have mercy on him) narrates from Sayyidah Aishah (may Allah be pleased with her) that she said: We do not know of anything that releases a person in ihram except tawaf of the House.
What we will mention, if Allah wills, in the issue of making a stipulation (istithna') in Hajj is evidence on this, and success is from Allah alone.
