I have one of the good old Otii devices that I have not been using for a couple of years, so I wanted to firmware upgrade it. However, this has given some unexpected issues.

I have both tried to firmware upgrade it from Otii 2 and Otii 3.

The output from the log from Otii 2 looks like this:

If I try to firmware upgrade from Otii 3, the GUI indicates that it has been flashing it and then it says “Reconnect device” like shown here:

But reconnecting the device doesn’t help.

Do you know about a workaround for this issue?
