These are NOT cramfs images - these are encrypted cramfs images. Before you try to mount them on your system (or just open them with cramfsck) you need to decrypt them. And that's where the crux of the matter is.

The images are encrypted by some algorithm, probably a Cypher Block Chaining AES or DES. It would be possible to decode if we had access to the unencrypted images, and could pull the encryption keys out of them.

Our best hope for any solution right now is that someone will find a way to dump the image out of flash - hopefully via serial port entry, by command line tools; if that doesn't work - by unsoldering the flash chip off the board and reading its contents with a flash burner.

I don't think there is an easy autorun entry to be found. Perhaps someone will find it - that will be great. Otherwise we will wait for some new information.
