Hi all,

We have many phones within our organisation that need their firmware re-flashing.

Is there a way of doing this without sending the phone back to Cisco?

Sorry maybe I didnt make my question clear. Some of our phones have for whatever reason errored halfway through updating their firmware so have been left corrupt.

Is there a way we can force an update even if the firmware is corrupt ie. it doesnt know to look at the tftp server?

Have tried this, it seems the firmware is corrupt and needs completely resetting.

Is there a way to do this?

hmmm... If you are willing, you may try getting a capture from one of these phones when it's powering up. If it's trying to send any kind of tftp requestm you might be able to send it enough info get boot to a new image.

I don't know of any other options.....
