If the no service password-recovery command has been configured on a router, the break sequence will no longer work in order to get to ROM Monitor (ROMmon) mode to perform a password recovery. If this feature is enabled, the following message is displayed at bootup, indicating that the password recovery functionality is disabled.
System Bootstrap, Version 11.1(4675) [kluk 143], INTERIM SOFTWARE Copyright (c) 1994-1996 by cisco Systems, Inc.

Recovery from this state is possible. However, the startup configuration in NVRAM will be lost.
If a Cisco 1700, 2600, 3600, or 3700 series router has been configured with the no service password-recovery command and the enable password is not known, perform the following steps in order to recover the password:

Do you want to reset the router to factory default

Reset router configuration to factory default.
The router now boots with no configuration.
After software configuration change
PASSWORD RECOVERY FUNCTIONALITY IS DISABLED
no service password-recovery command has been configured on my router, so the break sequence will no longer work in order to get to ROM Monitor (ROMmon) mode to perform a password recovery. I have followed more Cisco documents that explain the procedure to restore the default factory configuration, but none of them works.
http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gtnsvpwd.html
The system doesn't react to the receipt of the command "break".
My router is 877 with IOS 12.4(9)T5, and bootstrap 12.3(8r)Y14.
How can I restore factory configuration?
Thanks in advance.
Hi there! i am unable to enter "y" when router prompts to enter factory default configuration[y/n]. can anyone help. Thanks...
Thanks, I did it calmly and it worked for me, when the router finished loading the image #### OK, I counted up to 8 or 10 and typed Cntr + Break very slowly and it worked. I clarify that it took me many attempts and hours, but then it was very easy.
Note: do not quickly type CLT + Break

Hi All,
My issue is bit different from above resolution. PFB my problem and guide please.

@Tahir Munir you must have erased the flash or deleted all the IOS files from it before you reloaded the router so that it can't boot. In that case, paragraph 4 of the original post may apply. But the 2821 router went "end of support" 7 years ago so you might have trouble locating any documentation or IOS image for it, as they will have been removed from the Cisco web site by now.
