It sounds like you have done this to some extent already.  Try the software recovery options:

Have you booted over TFTP and ran diags from a booted system?

Its intesresting that the MAC_ADDR variable is not set either...  I am really starting to thing something failed...

In rommon see if it lets you "set MAC_ADDR" to the mac address listed on the unit.  This is more me wondering what happens than knwing what I'm talking about by the way...   There is a remote shot it needs that variable to go further... long shot though...

I think there is a hardware problem whith flash, do you?

Sounds like the flash may have come loose.  Re-seat the flash and try again.

You're using a 3750X so loading the IOS is as easy as booting the IOS from a supported USB stick.  You don't need to go into XModem.
