CISCO3945E/K9 - password recovery disabled / break into ROM issue

[Costinel Socol]

Dear All,

Can you Please help me with some advice regarding the following issue?

We have a CISCO3945E/K9 for which password recovery functionality was disabled.

I have tried to factory reset the router but i'm not able to break into ROM.

I have tried everything possible, even to remove the flash card but i'm not able to break into ROM...

Do you have any idea how cold I reset the router to factory default?

Hi Georg,

While trying to break sequence when mentioned prompt appeared nothing is happening.. booting process is not interrupted, it continues until it's finished.

Thanks !

Kind regards,

Hello,

check if your flash actually contains a valid IOS image (dir flash:)...

May be client sending "Ctrl+Break" that is not recognized by the device.

The sequence after that site recommend to issue the brake command does not appear on CISCO3945E/K9 booting process.
