Yes I did the process as you mention above, the update happen succesfull but still I am dealing with communication error problems.
The eventide unit fail from the desk, and i will go to the support in Greece and check if this is the case.
The main problem is that the H9 software cannot communicate with the right way with the device, is loosing the connection,
and i cannot enter in any midi menu of the device, and send the clock in the device.
Thank you, i will try the support and i will come back.
