Just a step further but my problem still not solved.
I installed the last firmware update but apparently it does not reinstall apache2
I still do not have the UI (http:mybookliveduo/UI) working.

Surprisingly I noticed also that many of the scripts that were present in /usr/local/sbin are not there anymore in particular I miss the /usr/local/sbin/factoryRestore.sh also WinSCP (TFTP) can not connect anymore (maybe something not enabled in ssh …) therefore I do not know how to do a new factoryRestore
