title: Google Developer Console - reuse deleted credentials
body: <p>I accidentally deleted my production OAuth credential for my Android App, from the Google Developer Console.
  When trying to add it back, using same SHA1 it says it can't, because the SHA1 is already in use. I've waited 10 days, and it is still not working.</p>
  
  <p>My Question is, Is the only way to solve it is to create a new Keystore file ? 
  that means I can't upload an update to Google Play! this is insane..
  Google Support is now supporting only payed customers so emailing them is not an option.</p>
  
  <p>Anyone has a better Idea?</p>
  
  <p>Thanks a lot,
  Giora.</p>
