Hi, I met similar problem

Hi, I met similar problem when I tried to upgrade my 7941G from SCCP to SIP. 

I used to successfully upgrade a 7940G from SCCP to SIP with the tftp32 server. But, with 7941G, it seems the firmware files are much different.

Now my 7941G  only showed a dark screen to me and stopped working. It looks the phone refused to pull the firmware from the server as I can't see any files happened. Maybe the firmware we had is not enough, I guess.
