I'm following the Guide posted on the 24th Oct to virginise my iphone running 1.0.2 (unlocked etc by seller). It took hours to get connected with Cyberduck but eventually it did (6 hrs later - total fluke). Anyway, still on the "backing up the seczone" section but had a response from the Terminal and not sure whether to go further skipping the step as it's not as described.

I should be getting:

cd /usr/bin
followed by Return. Then type
followed by Return. You should see a print-out similar to this. Good. If you do not, there is a problem, and you should post a forum topic with questions.

Obviously I'm not! I'm seeing:

# cd /usr/bin
# ls
zsh: exec format error: ls

Ideas greatly appreciated!

All the best.
