- For the FlashROM update, CF memory card (32MB or more) is
used. You must prepare a CF card in order to update the FlashROM.
The CF card must be formated by FAT16, or must not be re-formatted
from the default format (since purchased.)
SHARP recommends that you make sure the prepared CF card
is correctly recognized by the Zaurus before you atempt to
update the FlashROM.
In order to confirm;
- insert the CF card,
- invoke "File Manager" application,
- change the directory to /var/mnt/cf/
(After invoking "File Manager", tap "upper arrow" icon
twice to change directory to /root/, and then tap respective
If you see "NotAvailable", the CF card cannot be used.
- Make sure to take back-up of important data onto your PC by
using PC synchronize software before you start FlashROM update.
NOTE THAT THE ROMIMAGE VERSION 1.10/1.11 WILL ONLY WORK
WITH THE UPDATED VERSION OF
USB MCCI DRIVER
AND SYNC SOFTWARE (
Intellisync for SL
). Please refer to the readme file that comes in the updated
SYNC software archive for how to update the software and how
to back up your data.
Data will be lost or altered during the update process.
- Once you take back-up of all important data from the Zaurus, turn
off the Zaurus.
- In order to extract the downloaded archive on your PC, create
a folder, (such as c:\tmp), copy the downloaded archive, and
Once executed, you will find "romimage" file. Copy the "romimage"
file to the root directory of the CF Card.
Make sure to remove all other files from the root directory
of the CF card.
- Insert the CF Card to Zaurus properly if not already done so.
- Make sure that AC adapter is connected to the Zaurus, and is
actually power supplied.
IMPORTANT NOTICE (WARNING)
MAKE SURE TO USE AC ADAPTER TO UPDATE THE FLASHROM. WHEN
CONNECTED, THE ORANGE LED ON THE DEVICE WILL TURN ON. Note
that If the AC adapter is not used, the device will not perform as
expected in the following instruction.
Note that the AC adaptor that plugs into the cradle can also plugin to the bottom of the Zaurus and should be plugged in there when flashing.
- Open the battery compartment lid. Make sure you DO NOT take
- While pressing [C] and [D] keys, push "FULL RESET" button
once. "FULL RESET" button is located on the lower right side of
the battery compartment.
- When successfully pressed, the green LED (with "mail" symbol
print) and orange LED (with "battery" symbol print) will turn
When these LEDs are turned on, the update program starts.
IMPORTANT NOTICE (WARNING)
DO NOT ABORT, or UNPLUG AC ADAPTER WHILE LEDs ARE ON. Aborting
or unplugging AC adapter during the update may cause fault,
or damage affecting the Zaurus.
If the orange LED did not turn on, while the green LED is
on, the AC adapter may not be conected properly. If this status
happens, WAIT TILL THE GREEN LED GOES OFF, and DO NOT push
FULL RESET button while green LED is on. ABORTING the update
by pushing FULL RESET button while green LED is on willcause a
serious fault, or damage that affects the Zaurus.
- In approx. 3 minutes, the LEDs will turn off. When turned off,
FlashROM update program is now completed.
- Pull out the CF card, and push "FULL RESET" button.
- Close the battery compartment lid, and slide the battery
replacement switch to "NORMAL OPERATION".

system now starts.
3) Trouble Shooting
The orange LED will trun on, but the green LED will not, even
pressed RESET button while pressing [C] and [D] key.
CASE 1: OS will boot, and LED will not turn on.
Make sure to only press [C] and [D] key when you press FULL
RESET button. Update program will not be invoked if the other
keys are pressed.
CASE 2: OS will not boot, yet LED will not turn on.
Make sure the CF card is inserted properly. Remove the battery,
and leave the device for a several minutes. After leaving device,
re-insert the battery and the CF card properly, and try the update
No lights, no power, nothing.
Try removing the battery for 5 minutes and then reseting the device.
Nothing else works and my Zaurus wont turn on.
Try this: (Of course at this point there is no guarantees.)
1. Hard reset (holding down the reset button for a good 10 seconds)
2. Removing the battery for 24 hrs. (This should let the z internal
battery drain out)
3. Reflashing with a lower ROM (Such as 1.02 to start.)
4. Flashing back up to the one you want.
