Question before I upgrade - can I go back if it doesn't work?

Hi all,

I've never upgraded my Cybook (I have version 1.0.681) and am a bit nervous about doing it ... after all, I am mostly happy with how it works right now, except for the fact that I can't read PDF files. Most people seem to be happy with the latest upgrade, but still, I would feel better if I knew for certain I can go back if things don't work out as expected.

So, I have a few questions:

- Is it possible to "downgrade" from version 1.2.796 to 1.0.681?
- If so, how is it done?
- Should I take precautions before I upgrade, such as making a backup of my system, and how can I do this?

Thanks in advance
Florence

To downgrade you would need the 681-update_kernel file, I suppose even the fmt version that formats the ram completely before installing the firmware - you can write to bookeen, maybe they can send you the file.

I doubt that you will need it though, the latest update is really stable.

You should always make a backup of your cybooks content before you upgrade, other than that there should not be anything to worry about, just make sure that the cybook is fully charged before you run the update.

Thank you Pulp, that's just the information I was looking for! I guess I'll just have to take the risk and do the upgrade then...
