Spark partition doesn't boot

Hallo,

I was updating my Amiko Alien 2 twin tuner and the power got disinterupted. Since then I can't boot the Spark partition anymore. I was upgrading from an official firmware to an official firmware. I've been browsing this forum for for solutions withouth succes.

The reciever freezes while booting.

Anyone an idea how to fix it? The reciever is only a week old.

Thanks for the suggestions. All our attempts using a a rescue image had failed before, because we weren't using a Kingston USB-stick.
Formating the USB-stick first with an HP tool did the trick. I'm very happy.
