  1. My SD card does not work either. I expected that this time Bookeen would give their costumers a way of bypassing the SD card for upgrading purposes.It didn’t. And it is becoming a little bit frustrating now. If I should have no real hope, please Bookeen tell me now and I’ll return the device immediately. I do not want to be stuck with firmware 1.0 for life.RegardsNelson


  2. This update worked very well on my Cybook. I can now open even large PDF documents without making the reader crash (or being unable to read it because of the screen size).Suggestions for the next upgrades: 1) Folders in the library, please !2) a functionnal delete button would be practical ;3) and epub support would be a definite plus too.


  3. This “upgrade” has made a previously readable pdf file so that the pages are blank now. I deleted it and put another copy of it on the reader and it’s still blank. It was not blank before the “upgrade”.This is why I hate putting these damn untested and untrustworthy upgrades on my cybook: I never know when it will actually make things worse. Let’s see . . . first upgrade made things worse, second made things better, third made things worse. Now what?


  4. Dear Christine,Our support team sould be able to solve your problem, could you send us a mail . You will need to send us your pdf file so that we can see the problem with that isolated bug.Best regards,Guillaume


  5. I experienced the same problem with some of my PDFs.It only seems to occure when fonts are not embedded into the document (what is the case quite often).


  6. I would love to see the possibility to redefine the sidebuttons (music/delete/+/-) with other functions in one of the future updates.For people like me who do not use the Cybook for listening to music the buttons could be much better used for quickly:*Adding/removing & changing between bookmarks*direct access to dictionary lookup*zooming in/out in PDFs*increase/decrease fontsizeThis and the upcoming foldersupport are the only things I really miss on this great device.


  7. The pdf has been sent, and I will be posting your response, or lack there of, on my blog. By the way, nobody is going to read if they have to flip right to left for each and every sentence, which is what your new pdf zoom does. Stating the obvious: why don’t you allow the text to flow in pdf files? I know some are made so it won’t, but many are made so it will.


  8. hellovery well for me the latest update.the cybook have survived a travel to cuba and another to egypt.i´d like to load wikipedya as most pda´s can,other folder management and(why not?)a software capable to enter a word to look up.congratulations for your work


  9. Dear bookeen-developerAs next step it would be great to see page number in ebook (prc) files. That is still missing. With that feature, the book would be perfect :-)Regards, Michael


  10. Could you please make sure that the dictionary-lookup-selector always goes back to the last selected word of a page with the next update?Usually we read pages from top to bottom so after one lookup the next selected word will be below the first one.It does jump to the last selected one if the lookup failed, but it currently starts at the beginning of the page again when the lookup was successful – that little change would spare us a lot of moving the selector around if we have more than one words to lookup on one page.Thank you 🙂


  11. Hi, just bought a cybook gen 3 (*great* product, congratulations), and my version of the boo reader is 1.2 build 802. What are the changes since build 796 ? why isn’t this new software update available from your website ?Some suggestions for future updates :- Please, *please* add folder support for the library. Or possibility to filter the books on the library by filepath (enabling or disabling folders), not just sorting them.- It would be great to be able to know on which page of a book we are currently reading. I know this will change anyway based on font settings but since there is a feature allowing the user to jump to a specific page, I think it would make sense anyway.


  12. I note that the email newsletter #8 that I received today says “The [next new] firmware update should be released at the beginning of 2009″Anyone have any better information about what Bookeen mean by the beginning of 2009 ?


  13. My cybook has version 1.1 tried to update to 1.2Put software on root of SD, tried Kingston, OCZ, and Transcend, nothing happens. Am I missing something. Looked through the menu to spot the file, can see anything other then books and the pics that were already on the cybook when I bought it.Tony


  14. I appear to have got the update to work. I did not understand the instructions. Turn on the cybook with the sd card installed, then as soon as the cybook logo appears and before it completes boot up, press and hold the centre key. I may not be the only person not to get this. Tony


  15. vantadr, recent Bookeen newsletter (number 8, I think) promised it in the beginning of 2009.Wait, that is… NOW! :-)I expect a major upgrade, and I expected it in the next few days.Am I expecting too much?…Come Bookeen, there are so many people – your costumers – waiting for this!RegardsNelson


  16. Would also be interested when a new firmware release will be coming as I am looking at purchasing another Cybook if the next upgrade impresses, like folder support as mentioned previous and better usable menu functions for scrolling through a large library.


  17. Is there any chance that the Cybook will add support for non-encrypted epub files? I know you can’t support the DRM due to mobi’s strict licencing agreement, but surely you’re allowed to support it in an unencrypted form.


  18. Any one in this blog is asking the same question:public”When will Bookeen Release the new firmware update with folder support?”Can Booken give us a realistic release date?Regards


  19. Adobe today announced an SDK for portable devices that supports PDF and ePub formats. Bookeen is listed in the press release as planning to incorporate the SDK into their device sometime this year. No idea how this will affect PDF reading on the Cybook, but at the least this will mean ePub support. Nifty.


  20. 1) For the next upgrade please try to speed up the opening process of the cybook. The Sony reader stars very fast! It’s frustrating to wait so long when I want to resume reading!2) The Lookup option should be available from a button, or should be on top of the menu list. It’s frustrating to wait 4-clicks long until I get to the lookup option in the menu!3) The bookmarks should be numbered for ease of navigation.4) Making small notes should be available also. You can type numbers when you want to go to a certain page, why not have all the letters and the possibility to insert small notes? Ok, the writing would be a hard thing to do, but here’s a sugestion: use the mobile phone system for writing. For example, you have a table of 3×4 cells. In every cell you have 3 symbols, at least. You navigate with the up-down-left-right button. When you get to the cell where the desired imput-letter is, then you press enteer for selecting the first symbol or use another button for selecting the second or third letter. For example: I get to the ABC cell; then I press once a certain button to get to B (because A could be the default selection); then I press Enter for inserting the letter. And so on. OK, it’s not very fast, but it shouldn’t be slower than the SMS sending. And we’re ok with it, most of the time! Of course, there could be other systems, much faster for writing. Do a brain-storming;). This capability would make the Cybook worth while!5) Why is the emty-text border so big? Please include the possibility to have the text all over the screen! The PC-software is very good when it comes to customization! Do the same with the cybook software. Learn something from Sony!6) The number of the page on screen is also a must-have!7) And you should make available a free dictionary for the cybook. It’s a competitive market and the the cybook should emphasize it’s Lookup option.8) There should be available a user-defined zoom level. Not just fit page, 70%, 80% etc. But also 73% if I want…The screen is small and for many pdfs this option is not enought. There remains empty scree-space…9) Please include a delete option. All the best!


  21. It seems that not v1.2 build 796 is the latest available firmware – at least on my one build 802 is shown. Is there any documentation around what are the differences? Or is it possible to download it somewhere?
