Hello, 

thank you for your reply, 
I'm looking for a way to go to ROMmon mode at the moment, and then I can follow the link, 

because when I boot there is no prompt to press anything to interrupt the bootsequence and go for ROMmon, 

thanks

Hello, 

It's work, after going to ROMmon menu I add bootfile from Flash and then the router boot again  

thanks man

You don't have this message during the boot process ?

PASSWORD RECOVERY FUNCTIONALITY IS DISABLED

Power off the router. 

Attach a console cable. 

Power up the router. 

Post the entire boot-up process so we can see what is going on with the router, particularly the error message(s).
