Fix a Badly Bricked Cisco 7961

[MDFF2008]

Badly bricked. Doesn't even display upgrading anymore, just boot lights flash and phone then turns off.

Located in Cockeysville.

If you were closer to Aberdeen Proving Grounds I would try to help you out. Did you reset to factory?
Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. ...
Release # and press 123456789*0#

Yeah I did that a few times, I was trying to flash it from SCP to SIP.

Any luck with this?

I thought Cisco made computer stuff, what is made from bricks ?

Cisco 7961 is a Voice over IP phone. OP was trying to convert it from one voice protocol to another and something didn't go right during the process and now the phone is disabled or 'bricked', as in worthless as a brick is for making calls.

Some recovery methods might still be possible, thus making the phone 'un-bricked'.

Bricked is the technical term for f*ked. They can be used interchangeably.

 

[MDFF2008]

I can see on my tftp server its calling for files but I don't think I have the right config files to get the phone to call for the firmware.

 

[Biggfoot44]

Ah ! Bricked = geek for terminally screwed up , vs shoddy masonary work.

 

[MDFF2008]

According to my research, you need to configure some like default loads file. I'm not sure about how to do that.

Out of curiosity, do you have other 7961's working fine on your system?

No, this was a first one I bought as a prototype.

I've tried to put the firmware back with TFTP but this is all I get

Is there no ROMMON type access to these phones when they brick? I have a hard time believing there isn't. Cisco is usually pretty decent about having a handful of ways to fix their gear when it craps out.

[MDFF2008]

I've done all that.

The phone calls for the term61.defaults file, then does nothing.

I set the root of the TFTP to c:\tftp and put all the files in the root.

This is the text of the defaults. I tried putting an absolute path for each file, and also a \ in front.

If it were a switch or a router I could be more help. I wish I had a phone around here (and call manager) to play with to help you.

gprimr1 - will you be at the MSI meeting later? I have a CUCM 8.6.1ES12 VM on my laptop...if you have a power supply for the phone, bring it along and I can try to get it back to a default image load.

Instead of having a thread called Lurkers Reveal Thyself maybe there should have been one called English Majors Come Out of the Bushes!
