With the Bootware erased it is a long shot you will be able to update the unit in the field but if running ElkRP2 version 2.0.40 make sure to have the latest M1XEP Firmware version downloaded then click the M1XEP Setup and click Find, Select the M1XEP and if the “Prg Firmware” button is not grayed out click the “Prg Firmware” to see if you are able to reload the firmware
