MAKE SURE YOU FOLLOW THE INSTRUCTION BELOW STEP BY STEP. 1. 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 SL-5500 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 directory icon.) If you see "NotAvailable", the CF card cannot be used. 2. Make sure to take back-up of important data onto your PC by using PC synchronize software before you start FlashROM update. Data will be lost or altered during the update process. NOTE THAT THE Ospack WILL ONLY WORK WITH THE NEW USB MCCI DRIVER AND SYNC SOFTWARE (Intellisync for SL or Qtopia Desktop). NOTE THAT the NEW USB MCCI driver is the same as the one released with Ospack version 1.10/1.11. Those who already updated the USB MCCI driver DO NOT HAVE TO update the driver to use above updated syncronization software. 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. 3. Once you take back-up of all important data from your SL-5500, turn off the SL-5500. 4. In order to extract the downloaded archive on your PC, create a folder, (such as c:\tmp), copy the downloaded archive, and simply execute. Once executed, you will find "Ospack" file. Copy the "Ospack" file to the root directory of the CF Card. Make sure to remove all other files from the root directory of the CF card. 5. Insert the CF Card to SL-5500 properly. 6. Make sure that AC adapter is connected to the SL-5500, and is actually power supplied. IMPORTANT NOTICE (WARNING) MAKE SURE TO USE AC ADAPTER TO UPDATE THE FLASHROM.

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 SL-5500. 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 SL-5500. 10. In approx. 3 minutes, the LEDs will turn off.
