The tablet is otherwise functional, yes. It's possible that it's a PEBCAK, but I followed the manual update instructions (that I found here). I also made sure to copy the upgrade directory and the manifest.md5sum files, so the entire contents of the downloaded zip file.

EDIT

PEBCAK indeed, but not the one that you may have expected. 'twas a file ownership issue.

Previously, I created the tarball with

Code:

tar -cvzf ../KoboRoot.tgz .

Which set the UID and GID values for the files in the resulting tarball to 1000 (my UID on my Debian box). Clearly that threw a wrench in the works. Instead, if I create that tarball like this

Code:

tar -cvzf ../KoboRoot.tgz . --owner=0 --group=0

the file ownership is kept correctly. I think what was happening was that some file somewhere couldn't be read correctly or that the Linux kernel had a right problem with a file not being owned by root.
