Mohamed,

you need to break that boot-up sequence, so that it bypasses the username config.

eject the flash card, that will put you at ROMON

You can use the following method to recover password.

NOTE** Before breaking into ROMMON, make note of the config register, though its probably 0x2102

1/     Power down the UC

2/     Eject flash card

3/     Power up UC, it will start into ROMMON

4/     at ROMMON1 enter confreg 0x2142 (remember to reinsert the flash card)

5/     type reset (UC will boot, ignoring config)

6/     press N for initial setup prompts

7/     at router prompt type enable

8/     copy startup-config running-config

now you are back in your normal config, so you can modify the accounts, and enable secret

also make sure you bring your interfaces back online, as it will be in shutdown mode.

once you have made all your changes

9/     type config-register 0x2102

10/     then write memory

ALL DONE !!
