I was very happy with my Cybook until this afternoon. I wanted to add new fonts. As I had already added some the day before, I thought it would be easy...

So I booted the Cybook, connected to my Linux computer and transfered a few files - new fonts, IIRC. Then I disconnected, using the correct procedure of unmounting the volume before unplugging the USB cable.

Problem: the "Connected" screen didn't disappear, even after several minutes!

I tried pressing the "power" button several times. Nothing happened. I pressed "Reset": nothing. Then, I managed to get it to reboot after pressing first Reset, then Power.

OK, I thought, just reboot and here we are...

But no! The screen indicating booting in progress appeared and stayed there. The system was stuck again: I couldn't access to the library screen.

Once again, there was nothing I could do, short of rebooting with reset + power. And then it was the "wait while I boot" screen again...

This is the first time this has happened. I already transfered files in both the Cybook and the SD card without any problem. Now, it's stuck and I don't know what to do.

I don't know if anyone had the same trouble?

If this persist, I'll e-mail it to Cybook. If it's a bug, they need to know about it.

Maybe you can reboot with the USB cable connected and if it works remove the fonts you added. I tested to add a lot of fonts but it only took very long time after I disconnected the cable until the library appeared again. But when I tried to choose one of the new fonts the unit rebooted so the font handling code definitely seems to be buggy.

I tried: rebooted the Cybook with the USB cable still connected and removed the fonts. Then unconnected and waited for the library screen to come back...

And it doesn't come back! So I'm stuck again.

There was a font cache file in the system directory mentioned in another thread that could be removed. It was called .fonts.cache-1. Maybe removing this file will help.

No, it didn't help. I still have the same problem. If I reboot the Cybook, it gets stuck at the booting screen stage, if I plug it into the PC, I can access the files, but once I disconnect, I can get back to the library...

I've e-mailed Bookeen about the problem, and hope they have a solution.

Did you try the reset produre ?
There is a little hole at the back, press it and it will reset the Cybook !

I remember that Delphidb96 once had a similar problem with his preview unit...he had to reflash it if I remember correctly. Reset would be the first thing to try though...

EDIT: I just reread your first post and realized that you already tried the reset...so that won't work I guess...

No, the reset button didn't resolve the problem, but thanks for trying to help.

Now, I've just remembered that shortly before my Cybook got stuck, I didn't only add a few fonts, but also deleted some ebook files in the /eBooks folder. Maybe I did a mistake and deleted a file I shouldn't have? A file with parameters or other necessary data?

Could someone tell me what files were in the /eBooks folder when they received it, appart from the free ebooks and ebook samples?

Try deleting your "Fonts" folder entirely and see if that helps.

I was too quick earlier, sorry I was about to go to lunch when I read your cry for help and did not take the time to read your whole mail before sugesting the reset you had already tried.
As for "what's on the Cybook" : it's detailed in the manual that only one directory is absolutely required for it to work , I believe it's called /System but I do not have the Manual in front of me, all the other directories (/eBooks /Music, ... ) are therefor in the context of this problem of no importance. Hope that helps ?
If you want I'll tar/gzip the /System on my Cybook later on and send it to you , just let me know ... (Ill be home in 5 hours time though).

Hi all! Thanks for your help! I tried deleting completely the /Fonts folder as Harry suggested, and it worked! The library screen has come back, and I could select and open books again. :2thumbsup

I'll email a note to Bookeen, to let them know about the bug.

Thanks again, I'm glad to be able to use this very, very cool reader again.

(But I sure hope they fix the fonts bug in the next 2.0 firmware...) :wink:

Excellent - delighted to hear that it worked :). Yes, there do appear to be some definite bugs associated with adding fonts, but deleting what you've added always appears to solve the problem. There are certain fonts that it appears that the Gen3 just can't handle.

All the fonts supplied with Windows appear to work OK, though, so it you stick to those (Arial, Times New Roman, etc) you should be fine.

My gen3 also stuck after adding some fonts from windows xp. But now even I tried to remove everything except the system folder. It still cannot work. Only usb connection is viable. Any suggestion?

You can try to remove the font cache file in system/ mentioned above if you did not already do that.

Deleting the "Fonts" folder and deleting the ".fonts.cache-1" file from the system folder, then doing a reset, should certainly fix the problem.

That's what fixed it for me, apparently. ;)

Did you figure out which font type or font was causing the problem? I've loaded 12 additional fonts on mine and haven't had a problem. My Font Family window is full now and I haven't risked trying to add more.

No, I couldn't pinpoint it on one particular font. I remember I had just added some of the fonts recommanded in this thread (http://www.mobileread.com/forums/showthread.php?t=15796). After fixing the problem, I was able to transfer anew several TrueType fonts, including the URW fonts and some who are packaged with MS Windows.

Edit: After some tests, I'm thinking the problem is not with a particular font, but with a bug in the font managing software. I tried added more fonts, and when the height of the Font family window gets bigger than the screen height, it freezes or reboots when I try to change the font. I got to that stage when there were 16 font families in the window. So, to be on the safe side, it's better to transfer no more than 13 different font families in the memory of your reader, in addition to the 2 (Verdana and Courrier New) already present when you purchase the Cybook Gen3.

My cybook is stuck for 10 days. Only one response from the Bookeen support. But not help. Just ask me to delete the .font-cache. But the files under the system is all deleted except the /system/user/config.dat. My screen shown what they call 4-color checker. I just wait and wait everyday for their help. I just suppose they will send me a firmware to reset the system. The methods that all you gave on the forum was tried already. None of them work. If any of you have a working cybook, may be try to do the following under linux: ls -alR system/ to see what files in under the system other than the .font-cache and config.dat. May be some important files is deleted by me accidentally or the config.dat file is corrupted. Thank you for your attention. A sadly guy w/o ebook.

On mine, there is a file 'icudt36l.dat' that's 10.151.536 bytes in size. I once renamed it, and my Cybook did the same thing yours does after that (the '4-colour checker' bit). I renamed it back, and all was well again. I think it's (part of) the firmware.

Maybe some undelete tool can help? The internal flash is FAT32 after all...

Yes, movenka, I think you are very right. I remember some files I've seen was deleted. But there is no way to undelete the files. Is it possible email me your icudt36l.dat and config.dat for recovering my system. Thank you
my email: sm69lover@yahoo.com.hk

sm69lover, I will send you the files you want (/system) but I could not do so via MobileRead because your profile states that you will not accept email.
Please change your policy and I will send you the files you need.

mbovenka & kleykenb :
Thank you very much for your help. I have adjust my profile. Your system package file is received. My cybook recover very well. That's magic. I think this file contains the
logo, the basic font and some other basic programs.
We wish we contain modify them some day, so that we can change our display of the ebook.

I'm curious though, now that you have a copy of the /system directory on my cybook, does that automatically mean that the ID of your device is the same as mine ? Can you see what it says (I think it is somewhere in the Advanced menu).

There's no way that's going to be the case - otherwise, when you re-flashed the ROM, your PID would change (and it doesn't). I have a vague recollection that an ARM CPU has a unique identifier which can be retrieved - if so, the PID is probably based on that.

Harry is right, I " cmp 01-icudt36l.dat 02-icudt36l.dat", both of icudt* are come from mbovenka & kleykenb. They are identical. So the PID is generated from the hardware, not the software. my pid now is G57S2P1UQI.
