What is this all about?
The imageutil is a small c program which is capable of reading and writing images to the flashrom of the Kathrein UFS-910 satellite receiver using its network infterface. The only prerequisite needed for this to work is a running telnet daemon on the receiver and a working ethernet connection with it.
The tool has been tested on different kinds of images and should therefore work under nearly all conditions. It should anyhow considered to be highly experimental and used with caution. I do not take any responsibility if eats your cat hides your socks or fries your reciever.
How do I use the tool?
Imageutil is a shell application written for linux based systems. Just call the util by it's name in a console and it will give you it's usage information containing example on how the different functions work.

How can I obtain this tool?
At the moment I am releasing a binary only version of the tool. You can download it below. In the near future I intend to release the source code under the GPL, but before this can happen I need to clean up the code and clarify some other things. If you are eager to help me with the development please contact me directly via mail.
