Hi,
We've recently changed data line providers and now have some Cisco 877 routers we'd like to reconfigure and use at other sites. Although we own these, they were configured by our old data line providers, I'm having a hard time of resetting them to factory defaults and am after some advice.
The simple, hold down the reset button until it restarts does not work.
If I press the reset button within 5 seconds of power up to load the default rom image, I get the below:

Self decompressing the image : ############################################################################## [OK]
I assume from this the required bin has either been removed, renamed or overwritten.
As soon as the router boots it requires a password and I dont have the password to be able ftp files in and out of it.
Hope you guys can help.
Thanks,
Damien.

Have searched "router password recovery" here or on cisco.com ?
Hi Paolo, thanks for the response, yes I have as well as being familiar with cisco password recovery techniques from previous experience. In this scenario it looks like i should be using the rom monitor prompt but I am unable to access it by using the break within 60 seconds of a hard reboot.
Hi,
which terminal emulator software are you using to connect to the router and which keys are you using as break sequence ?
Regards.

Hi Alain, I'm using PuTTY
and CTRL Break, apologies forgot to add that bit.

If you are using an USB / serial adapter, replace it with one of reputable maker, that is able to send ctrl-break.
877 right? Look at the back of the router. There should be a tiny "Reset" button. Have you tried that?
