Thanks for the quick reply.

Better ask thank do something stupid, that's what I always say. Good think I didn't try to do the above procedure. Here's how I UPGRADED SPARK to a new version, using the USB port:

1. Download the new software (I got it from http://www.amikostb.com/?q=product&id=8 )
2. Unpack the archive to a folder and copy it to a USB stick.
3. Plug the USB stick into the receiver, wait for it to read it.
4. Press MENU on the remote, then go to System - Upgrade - Upgrade by usb .
5. There are system folder here, so go to the bottom and select STORAGE - C - yourfolder
6. Find the file version.xml and select it, you'll see a statistic of the version currently installed and the version you are about to install.
7. Press the RED button on the remote (UPGRADE) and wait around 5 minutes, you'll see some progress bars signaling elapsed stages per remaining ones.

It worked for me.
