Simply,
1. Fire up the RD-8 and connect it to the PC
2. Run synth tool and it should show the RD-8 and you can click on [Get Started]
3. Click on update (on mine the update page came up automatically)
4. Turn off the RD-8 and turn back on but with a pin or an item on similar size to hold down the DFU mode button in the hole next to the USB port
5. Once powered up RD-8 should look "dead" and synth tool should start updating
6. one the update has transferred the display on the RD-8 should display "wait"
7. "wait" will disappear from the display and the RD-8 will automatically reboot finshing the update process.
