a registered e-mail account on your Vita (fail-mail)
Note: This is an example why you shouldn't share your registry files with anyone!
Depending on your firmware and preference there are different ways to do this:
Fail-Mail trick - for firmware(s) 3.00 - 3.52
1) Send yourself an e-mail with the following support_uri as link:
email:send?attach=vd0:registry/system.dreg.
2) Open your E-mail App on the Vita, wait for the mails and click on the link in the first mail
3) Now just type in your e-mail address and send back this e-mail with the registry file as attachment. You will notice the E-Mail app close itself, thats normal and supposed to happen! :)
5) Retrieve the dumped file with your PC's e-mail client.
6) Open the file with any HexEditor of your choice to find Account and Password in plain text!
(search for "privacy_confirmation" and it should be right above)
Profit! :D
