Cisco UC 500 Config Issue

I have a problem with a UC 500 i'm locked out of. I was following the steps to reset a lsot enable password.

Ctrl break on boot
confreg 0x2142

After boot, enable

copy start run

This is where I ran into the 1st problem. When I tried to copt the startup config, I get the error "non volatile configuration memory invalid or not  present"

So, thats a problem. I don't have the startup config, and I need to at least boot the UC back to it's working state with the proper config. I have not attempted to write anything to ram, so I went back into rommon, to set the confreg 0x2102. I then reset but it does not go back the the prior config, it seems to stay in the 0x2142 boot which essentially is a blank config. Help!

I've written nothing to mem. I'll be back onsite this morning and dir NVRAM and post the output. The client had a spare which I picked up last evening, then performed the same steps I did on the production box, and it work as it should. I have informed the client that I beleive the NVRAM is corrupted, which is probably the case. I'll verify that today.

DId you wrote the config after that you rolled back to 0x2102?

he is trying not to loose the saved configurations thus he shouldnt write mem till we are sure what happened with the old saved configurations
