Can't install develop apps

[tithos]

The F Series Wiki tells me to do the following:

Develop account for 2013 TV`s:
username: develop
password: sso1029dev!
Procedure:
Press the smart hub key
Login to the develop account (Menu--->smart features--->Samsung Account--->Login (credentials are user name: develop; password: sso1029dev!)).
On the smart hub screen there is a 'MORE APPS' tab at the BOTTOM, click that.
Select OPTIONS, on the TOP RIGHT corner of screen that comes up.
Select IP SETTINGS from the drop down that comes
Enter the IP of your pc
Select OPTIONS on the TOP RIGHT corner
Select APP SYNC from the drop down list.

The problem I have is that my tv (f6300) does not allow me to enter a password unless I enter a valid email. develop does not work.

Has any one solved this

Enter "develop" as username, and leave password blank ...

Works for all F-series I tried it on.
