Change Mitel 6940 firmware

[pschu]

Hello all, I have a Mitel 6940 with the Mitel MINET cloud firmware that I would like to get working on my onprem Mitel connect system. I've read that I should be able to upload the SIP firmware to the phone. I can get into the web interface of the phone and I see that the SIP firmware is loaded in the inactive state. How can I tell the phone to boot into the other firmware?

I when I try to update to the firmware file 6940.st that I pulled from my Mitel HQ server I get the attached error message.

I was able to get my 6940 that had Mitel MINET firmware upgraded/changed using this document on page 761 section 8-10

Would you by chance be able to share the SIP firmware you are using? I don't have access to the Mitel portal

This is exactly what I am trying to do but I can't download the firmware either

In an unexpected turn of events, Mitel posted the SIP firmware publicly
