Firmware installation issue

i just got an electra one from ebay with a firmware version 0.9.11
with this version i cant use the electra one console to upgrade the firmware.
any idea how i get to the currrent firmware build ?

Maybe try this as an intermediate step Firmware 2.1.0

Just press the update button on E1 back panel (the recessed button next to the MIDI DIN connectors). That will force E1 to go to the update mode. Once in the update mode, you can use the Electra One console to flash the latest firmware.

Let me know if it worked for you. Cheers.
