i have a bad Day. I try to upgrade a 4500 M Router from ios version 10.3 to 11.3. I made a copy of the old boot image and downloaded by tftp the new one.
After reboot i get the messages crc error and the system goes in Rommon mode.
I study the Web and Cisco Forums but i found absolutly nothing to recover the boot rom.
The help was xmodem or tftp but the rommon has no command option like xmodem or tftp.
What can i do?
Is there any way to get the System online again.
