I was going through the Lightning Trailhead, which at one point wanted me to change my domain and promote it to the users. After this step I am unable to login into the same Dev org. Since it is a dev org, there is nobody else that can login and help me.
I tried reseting the password, and every time I try to login it just redirects me to the same login page. I changed tha password already 5 time and still have no success.
Any suggestions?
