How did Obito awaken Rinnegan?

Obito did indeed have Asura Otsutsuki's chakra thanks to Hashirama's cells. However, he couldn't get his hands on Indra's chakra. Madara Uchiha also awakened the Rinnegan because he himself was Indra's Reincarnation, so when Asura's chakra mixed with Indra's, it gave him the Rinnegan.
