The most sure fire process is connecting your pedal via USB to a Mac/Pc, opening up H9 Control, and initiating the update process in the Pedal tab > Stompbox Software > choose first option > click on Intall Software. Once that’s done, to restore Factory Presets and all System settings, power up the H9 while simultaneously pressing the Right Footswitch and the big Knob until [INITIA] is displayed.
