rommon 72 >ping 1.1.1.6
Host 1.1.1.6 is alive
rommon 73 >boot tftp://1.1.1.6/cat4500e-universalk9.SPA.03.08.06.E.152-4.E6.bin
Received device in rommon state. Attempting to use mgmt port and TFTP to download necessary files. I can ping, but fail at TFTP download. Attempted to remove Windows Firewall on my laptop (TFTP server), but without the FW I can't even ping. Any ideas?
Tftp Session details are ....
Filename : /cat4500e-universalk9.SPA.03.08.06.E.152-4.E6.bin
IP Address : 1.1.1.4
Loading from TftpServer: 1.1.1.6
Tftp session failed: maximum retransmission count exceeded

Strange that without firewall the ping fails.
Seems a firewall configuration problem.
Do you have a third party firewall that works with windows firewall?
Try to disable temporarily antivirus and others security software and try to add a rule on your firewall to allow UDP 69 port for incoming traffic.
Use netstat -na from your ms-dos prompt to check id tftp service is up and running.
You must see something like
UDP 1.1.1.6:69 *:*
Let us know.

UDP port 69 was open, but Firewall had certain aspects of TFTP traffic restricted. Made some changes and moved data successfully.
Thank you very much for your assistance.
Have a great day!

Thanks for the reply and suggestions.
I agree with you about the FW/ping issue. I would've expected just the opposite. I'm using TFTP (Jounin) and have performed this procedure before on 3560s and 2960s, but never on 4500-X.
I'll use your suggestions and will reply with feedback.
Thank you!
