I have results similar to the above, and when trying a ver.0.32 img backup of either rootfs or optfs, the program stalls at the end and I have to pull the battery out to stop it.

The length of the image files seem right, though, so they *might* be good to be restored. I don't know whether the 0.32 restore command now works or not, either.

I haven't the guts to try to restore by now , and I'm doing backups both with ver.0.32 and with ver.0.56 - in the hope one is good at least
