Hi Tonny,

Switch needs a ROMMON upgrade to boot this image. 

Current ROMMON Version:
ROM: 12.2(31r)SGA1

The Recommended ROMMON version:
12.2(31r)SG3
 
This is documented in Table 4 "Catalyst 4900 Series Switches, Recommended ROMMON Release, and Promupgrade Programs " here:
http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/release/note/OL_9592.html#wp305142
