I can confirm that it is working.
Going to SIP version results in same brick.
Installing Teams version brought it back to normal state.

Will check with Yealink now how to revert from Teams to SIP

sure, it's connected to network without some restriction.
btw it was working(only once) with sip rom installed and teams rom install over web control(CP960-73.15.0.45.rom) with newer roms it was not working and now i am not able to reproduce it, bcs it's not booting sip(triangle logo) or teams(yealink logo)..it was tested with +- 6 version from teams and sip

RE: Unsuccessful upgrade caused CP960 hangs at Initializing
Try to install latest teams firmware via recovery (CP960-73.85.0.5.rom)
check if you can connect to web-interface and login with admin/admin and make factory reset.

If it works, try to install CP960-73.84.0.25.rom SIP-Firmware via web-interface. If it boots up, you can update to latest release via web-interface

Going directly from Team to CP960-73.85.0.5.rom results in the same brick for me.
