Performing the GPD WIN 5 Controller Firmware Upgrade #

Unpack the downloaded file onto your GPD WIN 5. Locate the executable titled GPD_WIN 5_V1.12_260512.exe and launch the application by double-clicking it.

Following a brief pause, the utility will display the existing Device FW Version (v1.08 for this example) alongside the Package FW version that will be installed (v1.12 in this case).

Should the version digits vary, select the Update button to initiate the controller firmware installation.

The procedure requires approximately sixty seconds to finish. It is vital that you do NOT power down the handheld, exit the program, or engage any buttons during this window.

Once the installation is finished, a confirmation message will appear on the screen.

Select the OK button; the application will shortly refresh to indicate that the Device FW Version has successfully shifted to the newest release, which is v1.12 here.

The program can now be exited. It is recommended that you restart the system once before resuming normal use of your GPD WIN 5.
