Gekko Cable HD - Firmware how to ?!? Please help ;-)

Hi friend´s !

I have a Optibox Gekko Cable HD and a try to get a Firmware Update.The Receiver is new.

I used this file [Only registered and activated users can see links. Click Here To Register...] and this loader:

[Only registered and activated users can see links. Click Here To Register...]

When the loader is finished i restart the Receiver new,but i only get a black screen.The Box is not booting anymore :-(
