I tried 432 433 434 they all came back with the same error

Already did a factory reset and then tried to upgrade?

Also maybe try a small downgrade to 104.431.0.30 https://support.yealink.com/en/portal/do...42ab6f8d6e

tried factory reset downgrade and upgrade firmware both failed with the same error
hmm

I am in Australia and got the unit from amazon.com.au but the unit report DECT European Union so not sure if that cause any issue
