Upgrading Firmware Using the USB Download Mode
The USB download mode is used for firmware upgrading. In order to upgrade the
firmware, the following are required which are provided to you with PWG-600:
• USB Driver files named “usbser.inf” and “usbser.sys”
• The USB firmware upgrade program file “Uploader_usb.exe”
• Firmware file named “bundle.bin”
The Firmware file “bundle.bin” and the “Uploader_usb.exe” file must be saved in
a single folder in your PC. When the “Uploader_usb.exe” file is run, it will look for
the “bundle.bin” file in the same folder.
The steps to enter the USB Download mode for firmware upgrading are as
follows:
1. Turn off the PWG-600 and remove the battery.
2. Press and hold down the “Volume decrease” key and at the same time
insert the battery into the battery compartment. The phone will then enter
the “Firmware Upgrade” mode with a message titled “Firmware upgrade
(USB)” appearing on the PWG-600 screen.
3. Connect a mini USB cable from the USB terminal of PWG-600 to a USB
port on your PC. A message appears on the PC screen asking for the
USB drivers. An installation wizard starts, guiding you with the USB driver
installation.
4. Note the COM port number for the inserted USB cable from Device
Manager under System Properties in your PC. It appears under the “Ports”
folder as “WIM Comm port (COM 7)” if ‘7’ is the <COM port number>.
5. The “Uploader_usb.exe” file shall be run from the command prompt as
follows:
a. Type “uploader_usb.exe <COM port number>” in the command
prompt and press the “ENTER” key on your keyboard.
b. For example, if the COM port obtained in step 2 is ‘7’ type
“uploader_usb.exe 7” and press the “ENTER” key.
6. The upgrade status is shown. Please wait while the firmware upgrade is
completed. The unit will restart once the firmware upgrade is completed.
CAUTION: DO NOT REMOVE THE BATTERY OR TURN OFF THE
DEVICE WHILE THE FIRMWARE UPGRADING IS TAKING PLACE.
REMOVING THE BATTERY DURING THE FIRMWARE UPGRADING
MAY CAUSE THE FIRMWARE UPGRADE TO FAIL, CAUSING THE
PHONE UNABLE TO BOOT UP.
