RE: W56H initializing/boot loop

I recently found 3 old W56H handsets laying around and according to this website they are compatible with the Microsoft SIP gateway, when I updated them to version they got into a loop where they start initializing then restart, start initializing again, restart again and so on which I can only seem to get rid of by disconnecting them from the base station, I tried it with a W60B as well as a W70B and I experience the same issue with both of them. Is there any way to update/downgrade these handsets to a working version without them being connected to a base station? or are there any other solutions to this?

Any ideas are very welcome.


Please make sure the base stations are running on the latest firmware.
W60B on or higher and W70B on or higher.

Kind regards,
