SIP On Mitel / Flashing 622d v2 7.0.SP11 Downgrade

« on: October 08, 2021, 09:55:33 AM »

Hey all,

I am facing my next challenge by downgrading a unuseable 622d v2 with SW-Version 7.0.SP11. If I press any of the buttons I do only recognise a audio response but there is no response on the display although the display shows a menu or the start display.

My expectation is that the phone has a corrupt firmware version. I wanted to downgrade it with the USB Updatetool. But the software shows that there is no software available for that phone, although within the zip file were upk sfor 5.5 or 5.0.
Is there a possibility to flash the drive or another firmware anywhere which I could use to get the phone running?

Thanks for replys

I managed to connect these type of phones by using GAP Profiles within the telephone system rahter than the right DECT profile

Hi all,
we are trying to connect some Mitel 612d v2 (SW 133.3.31). While connecting them the phone itself shows that it is successfully connected. But within the system the time exceeds and nothing happens. The phone is not registered in the system. Is there a incompatibility or how can I manage to get the registration done?
Thank you!
