Prophet Rev2 User’s Guide
Appendix D: Troubleshooting and Support
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. 
To restore your Prophet Rev2 if it is frozen.
1.  Power on the Prophet Rev2 while holding the glide switch to enter 
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. 
Contacting Technical Support
If you are still having a problem with the Prophet Rev2, contact 
Technical Support at support@davesmithinstruments.com. Please 
include your Prophet Rev2’s serial number, the version of the operating 
system (displayed when the Global button/menu is enabled), and the 
purchase date.
If you have not already reset the Global parameters and run the calibration 
routines (see Troubleshooting), you should do it before contacting Technical Support. 
It’s probably the rst thing they’ll ask you to do.
