Followed FN - 63170.
After C3200_RM_ALT.srec.124-15r.T1 is installed I still get the cookie warning and when I do a show cookie it still shows all 00 00 00's.
Can't get to the next step, TFTP or xmodem the new IOS image. It haults at rommon everytime. When I attempt to TFTP or xmodem the new image "WARNING: Cookie information is corrupt" scrolls down the screen and when complete I get a "Download failed, invalid image"...something like that.
Now I get more error messages...
