Cant Acces Dashboard, missing SSH login, factory reset?

Hey,

I treid to change my SSH login (standard: root- welc0me), butsomehow that failes, so wasnt able to access ssh. Trough the dashboard (mybooklive/ui/ssh) i tried to deactivate the SSH. Afterthat the dashboard crashed. When i tried to relaunchthe dashboard (mybooklive/) it jsut gave me the following errer-message:

Warning (2): Cannot modify header information - headers already sent by (output started at /var/www/UI/cake/basics.php:109) [CORE/cake/libs/controller/controller.php, line 647]

Notice (8): Undefined index: empty_passwd [APP/app_controller.php, line 77]
Notice (8): Undefined index: owner_name [APP/controllers/components/owner_api.php, line 115]

I treid to reset the MyBookLove by clicking and holding the Reset-Button for 4 secounds, but somehow that didnt work.

Any Help?;(
