With the device switched off, press a button (try different buttons and combinations, they differ from player to player).
Without releasing that button, plug the USB. Then the device gets detected as a Webcam. Then you have to install the drivers that probably came on your CD (also available here)
Use FRM Pro to extract or manage the firmware, which is located (hidden) on the flash.
To extract:
Go on Advanced mode
Right-click RSV and choose Set Working Folder, and then select an existing folder to dump the files to.
Right-click A, Get A image, B, Get B image, and Firmware, Get.
Don't worry about bricking the player, the firmware upload method doesn't depend on the firmware itself so if you have backed up your firmware you can always restore it, so there's nothing to worry about.
FRM Pro can be used also to replace individual files on the firmware without burning the whole AIMG/BIMG, and to reinstall the firmware.
