CISCO881-SEC-K9 router unable to do factory reset

[Raj_82]

We have configured the CISCO881-SEC-K9 router and sent it to the site. When we try to logging the router it was not accepting the password. I am we sure saved the config on the router. But we tried login with the password it was not working. I also tried with cisco default password but no luck.

I tried to reset the router which suggested by cisco website . it went into rommon mode 

Password Recovery Procedure for the Cisco 881 Series Routers - Cisco

rommon1> confreg 0*2142 

rommon2 >reset 

it says "rommon mode initialized" , but router does not reboot automatically to the factory default

it again came into "rommon1>"

I tried several time with same command it does reboot.

I did manual reboot as well after typing  confreg 0*2142  and reset. it does not reboot to the factory default.

if i reboot it came to <rommon1>  " 

After that I typed command to boot  "boot flash:XXXX.bin" . again router came up with startup config my password was not working 

I tried multiple times I am unable to reset it.

Could you Please guide me how to reset to factory default or skip the startup config?

Look at the back of the router.  Does it have a "Reset" button? 

If it does, hold it down and apply power.  Keep holding it down for 20 seconds and then release.

confreg 0*2142 and reset.

it is does reboot and skip the startup config again it coming to rommon1> mode.

Reset button does not make the router go into ROMMON.  Reset button only erases the config of the router.

We tried to reset the using " reset button" but was not success.  when we hold the reset button and then power-on the router it going into "rommon1>"  mode. 

we also tried while booting press fn+ctrl+B(Pause/Break) the same mode (roomon1>) it is going.

Is there any problem with the device or we doing something wrong to reset. Could you Please how to reset it

One thing I notice (perhaps it is a trivial detail or perhaps it is significant) there are several references to "confreg 0*2142" It should not be the character * but should be the character x

Thanks Richard, let me try with confreg 0x2142 and the update the status.

[Raj_82]

Thanks Richard, When I using confreg 0X2142 it is working.

Thank you very much.
