Solved: Cisco 1921 factory reset

arielpa · ‎05-03-2023

Hello,

I bought Cisco 1921, but I don't know password to this router.

Reset button doesn't work and I can't go into rommon mode - ctrl+break, ctrl+c, special command -> break (in PuTTy) doesn't work also.

How can I restore factory settings or go into rommon mode?

Thanks for your answer.

I couldn't go into rommon mode. I've read that it can be issue of my RS-232 cable or rs232 to usb converter. So I used another cable and another converter and DONE! It works. Router has new factory configuration.
