  • Put the unit on stock V15 first, and keep your own copy of the stock file from M-VAVE’s downloads so you can go back.
  • Back up your presets with the current firmware’s own export before installing.
  • Rescue: none documented for this firmware.
  • If something goes wrong, follow the recovery ladder.
