How to use bootloader mode

[minsushin]

Please understand that I use a translator first.
My prophet is not recognized by sysex library in bootloader mode.
Neither the usb cable nor the midi input are recognized.
Please help me.

Hi there. It's good to note that the Rev2's bootloader mode only works over MIDI DIN (not USB). You might want to open a ticket with Sequential support if you are having further difficulties.
