And which device is this 5.2 firmware for?
The Cybook Odyssey
Was that a serious question?
I don't think any of the older devices will still get updates...
True, but not everyone know that. So john's question made sence.

Odysey, all of them. Updating the second one. Or trying too. It seam to to be doing the same thing as with the last update ! Stuck to updating. Seriously, bookeen
No problems here...
The only new thing I notice, there is a new menu setting that allows the Frontlight to remember the light status when you turn it off and on again.
Did you do the update via wi-fi ?

I've been trying to revive the cybook, no luck so far.
No, I always do it manually. My advice is to search for errors on the Bookeen. Of course that should happen before the update when the device was still alive...
Others (on a German forum) did it succesfully via WLAN though.
Update took all in all not longer then 15 minutes, I think everything taking longer is not normal.
So there still might be an issue with firmware and bricked device? I think I'll wait for a while then.
Well, my cybook is definitively bricked.

Not sure, last time it did that. Then finally restarted, updated and all.
