Hi experts,
We just upgraded the firmware of our 7941s. All are good except one. It doesn't upgrade at all. I factory reset it by holding #, 123456789*0#.
After this, it's still not fixed. Then I directly connected it to a laptop as TFTP server with SEPxxxxxx.cnf, term41.defaults.loads, etc. with it.
However the phone is not responding at all. Then I factory reset it again the 2nd time. Now the speaker button & line button blink once, then it's dead. no power.
I also tried connecting a power supply but the same happens. the speaker button & line button blink once, then it's dead.
Can anyone help me how to troubleshoot it? Or the only thing I should do is forward it to TAC?
tnx

Try the alternate reset sequence:
3491672580*#
After that, wait, it can take 10 minutes without display activity to revive the phone.
Hope this helps, please rate post if it does!

Do packet capture and you will see that either the phone is not give a valid dhcp reply with option 150, or it reuest some file that the tftp server doesn't give.

Hello, I'm facing the same problem. Could you please share with me what was done to fix the issue? Thank you.

The only thing that I've done is set a specific pc as a TFTP server, then I copied all the phone's files from my CM for that particular model. Then when all was set, i reset it as advised then it works!
