Problem: Execute Extensions Pack in BD-D7000

[arivag]

Hi,
I would like patch firmware of the BD-D7000 for delete cinavia. Firmware versi?n installed in BD is 1015 (march '14). I have done the following steps:
1. Create account "develop" and configure Settings Server IP as 149.154.159.134 --> OK
2. Press User Application Synchronization for install widget SamyGO Extensions. BD download widget and install. --> OK. Now I have a icon SamyGOE in smart hub board.
3. I do clic in SamyGOE icon, then screen in black and I can read a message that says "Extensions Pack is Nested in this device".
4. Now, I tried connect to BD using ftp, net cat, ... but I can't connect.
(I tried : 'nc IP_BD 1023', but connection refused)

So, How can I connect to BD-D7000 using net cat, ftp, ...?
Is it possible?

Thanks!

Regards
