Firmware risk: Unsupported, and the author warns it can brick your device. It rewrites the firmware header so one model accepts the other's image and flashes it over WebMIDI, so back up your projects and samples first and use it at your own risk.SourceSource
About
A browser tool for flashing firmware files to the EP-133 K.O. II and the EP-40 Riddim over WebMIDI. Its headline trick is rewriting the four SKU bytes in a .tfw firmware header so a device will accept an image built for its sibling, which is how a K.O. II can be made to boot as a Riddim. It also backs up and restores your projects and samples.
