Downgrade Mitel 622d to 129.4.22
« on: October 23, 2017, 06:29:14 AM »
Hey Guys,

Maybe you can give me a workaround with my Mitel 622d telephone.
Normally I can downgrade the mobile phone by pressing ***76# and choose DOA settings
switch to 129...

But now, there is no DOA settings in the service menu. Are there any other tricks I can do? On the phone
is firmware 132.70.34.

Maybe you can help me?!

Greetings

It should be connected to a Ascotel 2065

so it is not subscribed yet? try to subscribe it and leave it for a few hours. It should auto-update... (At least it does when I encounter this in the MiVo400.)
