Password Recovery for Cisco MDS 9124 Fiber Channel Switch Not Working

We have two Cisco MDS 9124 Fiber Channel switches that we don't have the admin password to anymore.  I've been following Cisco's instructions from:

http://www.cisco.com/en/US/products/hw/ps4159/ps4358/products_password_recovery09186a00801258c3.shtml

But whenever I get to the "load:[image]" command near the end, it starts decompressing the image, and I get kicked to a "switch(boot)#" prompt for a few seconds followed by "Switch Login:" prompt.  Never am I at the "switch#" prompt to perform the "copy running-config startup-config" in Step 11, and the password I had changed it to during the "switch(boot)#" prompt doesn't work.

The switches still work fine before and after this process, we just can't log in as "admin."

What system are you using to connect?

The break sequence might be different and this is what might be ignored and the switch continuous to load normally.
Boot
Carl j is equal to enter, go ahead.
You at this point need to hit the send break signal to stop the image from decompressing, loading.

I was using a Windows XP laptop with HyperTerminal.

I tried Ctr+J to no avail, as well as Ctrl+Break.  Nothing's working.

I opened a case with Cisco and found out I am out of warranty for the device.  :(  So they couldn't help me.  I didn't even think it was that old.

Anyone else out there have experience with these things?

Hyperterm has the send break option under one of the menus and that is what you need to use.

The problem isn't that it's not breaking right -- I break just fine.  I break to get into the switch(boot)# prompt.  It's just that the instructions from Cisco say to load the image from flash at the very end, then I can "copy run start" but when I load the flash image it brings me to the switch# prompt.  The credentials I altered in switch(boot)# don't work at that prompt.

Then something is not right.  Could you check whether your startup conf is stored or loaded from a different location.
Can you change the password and add a new user and see if that survives?
What is the boot source?
I.e. make sure it is not booting from tftp and that is where the config needs to be saved as well.
Copy run tftp

Worked with Cisco support and solved it by loading an image from another location
