[ha@profindis.de]

Hello,
I have formatted the flash and rebooted the router C891F . The PASSWORD RECOVERY FUNCTIONALITY IS DISABLED, so that I cannot press the reset button.

I have copied the valid on the usb and conneted it to the router but it was not working. i receive the same outout:

If the IOS is in the USB then use the command "boot usbflash0:".

Hi, the problem i have is. I can not go into the ROMMON. Send Break is not working

[Kanan Huseynli]

Hi,

try to erase config by sending multiple break signal on boot. See below page:

http://packetlife.net/blog/2010/oct/11/recovering-no-service-password-recovery-service/

After it, I thing that next-reload will cause going to ROMMON, because startupconfig is empty and password recovery is enabled by default. At the final step recover IOS via USB (if available) or TFTP in ROMMON.

let's try...

connect console cable into the console port
set speed 300
reboot the router
wait 2 min
change speed to 9600
press "enter"

what will you get?

Hold on ... What are you trying to do?
Do you have the ROMmon prompt?

Thank you for helping.
