The forums give a wide latitude to posters and you can certainly post in any style you
wish. It is not a matter of being "wrong". I am in no way offended. (Perhaps annoyed,
but such is life, and it would be hard to "Offend" an ex-platoon Sergent.)
Try attaching you JBL to your MAC with the USB cable and see if there is anything in
the internal memory. (You might want to remove the SD card from the JBL before hand.)
There is a way to return the JBL to it's factory settings and reflash the NOR memory.
This could restore access to your internal memory.
You should also try the current (0.16e) firmware as it made a large number of
improvements. I would do so after restoring the factory settings and flashing the
NOR memory.
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;
