Dave Smith Instruments Prophet REV2 Mode D'emploi page 162

If the OS fails to load correctly when you update:
• The Prophet Rev2 is equipped with a MIDI bootloader, which will
allow you to reload the OS in the event you accidentally "brick" your
synth (permanently freeze it) while updating its OS.
1. Power on the Prophet Rev2 while holding the
bootloader mode. You'll see a message in the display.
2. Use a MIDI cable (not USB) to transmit the new OS to your synth. You
must use a standard MIDI cable for this. USB MIDI doesn't work in
bootloader mode.
3. As the OS loads, you will see the main display count upward from zero
to 99. When it reaches 99, a second count will begin. Do not power
down. The Prophet Rev2 will restart itself when it is done.
