Ran into this one again on a router I recently purchased. In searching the
archives for the methodology, I realized I had not documented the procedure
anyplace last time I ran into this last September of so.

The bug: with versions of IOS 12.0, upgrade is impossible. Copy TFTP flash
fails

The fix:

1) boot to rommon
this is done using the password recovery process - hit control-break key a
few times during the 1st 30 seconds of the boot process

2) this places you into the > prompt

3) enter the command 0x2101 ( not 0x2142, as is done during the normal
password recover process )

4) reload. this gets you to a  "Router(boot)>" prompt

5) erase the flash

6) now the copy tftp flash command works. ( maybe you can skip step 5 )

7) when done, enter config mode, and enter the command "config-reg 0x2102"

8) reload the router

9) life is good.

10) curse Cisco under your breath, but not too loudly, not in public,
particularly when your lab date is close
