Firmware Upgrade

[Start] > [Settings] > [Control Panel] > [Firmware Update]

You can check the handheld’s firmware version in the Firmware Update control panel. It is also

possible to load a new firmware image (from either the Flash disk or a MicroSD card) using this

utility. Firmware updates require a hard reset to finish the process.

New firmware for the handheld is distributed as two separate image files – one for the bootloader,

and one for the main OS image. Upgrading the unit’s firmware will reset it to a factory-default

state. Any data or programs you may have loaded (except on the Flash Disk) will be removed and

you will have to reconfigure the unit afterwards.

You have two options for copying the new firmware files to the handheld (both methods are

explained earlier in the manual):

• Copy them to the top level of a MicroSD card and install the card into the back of the unit.

• Use ActiveSync to copy the files to the top level of the unit’s Flash Disk.

Once the two firmware files are in the handheld, use the Firmware Upgrade control panel to install

them. In the “Select Files to Upgrade” area, pick either Flash Disk or MicroSD from the DISK

pulldown, depending on where you loaded the image files. Check both the BOOT and OS

checkboxes to indicate that you want to install both, and it will verify the existence of those files

and report their version numbers in the “Files Ver. In Storage” area of the window. If everything

looks good, click the Upgrade Start button to begin the installation.

Go to the Firmware Update control

panel to examine the current firmware

version, and perform an upgrade.

The top area shows the current

firmware version (406/405 in this

example).
