Now I think that there is only one option........ Create a new Microsoft account, register it for dev preview, sign in to the phone using this account, download the dev preview app, and then try again. Phew! That is a lot of work, but if it does not work even then, I think there is some problem with the phone itself. Try using Nokia Software Recovery Tool to reset the phone( I think you should try this first before creating a new account, I think this may be the key to solving the problem).Tried.
Still no luck.
Any other suggestion?
