I have a long (1024 page) pdb book that I have been reading on my jetBook lite.
Recently when I try to open it i get the "waiting for page" message and my top "bar" gives the correct name of the book and shows page 597/44 and the indicator light flashes and nothing happens. Any ideas?

That sounds like an odd hangup that I ran into when I accidentally pressed the
lanscape button, while I was reading. Mine got stuck in the repageation, with
the page numbers not really matching the size of the book.

I can't remember what finally got it back, I do remember going back to the
main menu and then reloading the book a few times. At one point I just
let it run the numbers up past the number that it said were in the book and
reset and it loaded fine after that.

Luck;
Ken

Thanks, Ken. I have since tried all kinds of things, even deleting and reloading the book without result. Still does the same old thing. I really would like to finish reading the book!

Well, there are a few things you can try, but it is still an odd problem.

First you can delete the file and then use the reset button on the back of the Jetbook.

If that didn't work, you can clear all the internal settings back to the originals by
using the Diagnostic Screen options as follows:

(Ignore the parts for the SD card if you don't want to re-flash the NOR memory or
update the firmware)

The thing is, you can fairly easily reset the JBL to factory settings and install the current
firmware on the device.

You should remove any SD card from your JBL and connect the USB cable to backup your
JBL's internal memory, to a folder on your PC's hard drive.

Reformatting the JBL's internal memory to FAT32 is a good idea and running ChkDsk on it
while you have the JBL connected to your PC with the USB cable is a good idea as well.

If you can get to the logo screen then you should be able to do this:

First if you only have one SD card then you will want to back it up to a folder on your
PC's hard drive.

Format an SD card for use during the update of the firmware. (I still use FAT16 for this
although I understand that FAT32 works as well.) The formatting will insure a clean card
and root directory into which the three update folders go.

Be sure to use a firmware update with all three folders to make the SD card. Insert the
SD card into the JBL.

Make sure the USB cable is not connected at this point.

Then you go to the Diagnostics Menu built into the JBL, it is here that you can do the
#13 - Reflash NOR and the #7 - restore factory defaults

To enter the diagnostics screen:
Reset the device. Then hold down three buttons. They are: "on/off" "zoom" and
"menu". When you see the jetBook screen let go of "on.off". Keep holding the
"zoom" and "menu" keys until you see a 16 item screen. It's tricky, so it may
take a couple of tries.

Then you can reflash the NOR Memory and reset the JBL to factory defaults.

After that is done reset the JBL.

Now you can update the firmware as you normally would.

Follow all directions and don't play with any settings you don't understand.

This procedure should fix any firmware related problem. If you have a valid download
of valid firmware and this doesn't fix the problem then it is a hardware issue.

Luck;
Ken
