IOS upgrade for ISR 4321 keeps failing

[glodynto1]

I am pretty sure I am missing something here but I have run into a wall and wanted to reach out to the community before anything else...

I have an ISR 4321 that is on IOS version 3.16.4 and I am trying to change the IOS version to 16.3.7 the current suggested Denali version.

I have ran the command

boot system flash bootflash:isr4300-universalk9.16.03.07.SPA.bin

And after reloading I receive the following error:

Package header rev 1 structure detected
IsoSize = 459902588
Calculating SHA-1 hash...Validate package: SHA-1 hash:
calculated 7289A83C:74AD2F89:AC671B90:7E782BD6:CDFC3A8B

SHA-1 hash doesn't match
Failed to boot file bootflash:isr4300-universalk9.16.03.07.SPA.bin

........

autoboot: boot failed, restarting...

After this the router reloads into the previous version. If there is any insight to this or if I am perhaps missing something, assistance would be greatly appreciated.

Thanks

This means the IOS file is corrupt.  Go to the Cisco website and download the file again. 

Copy the IOS into the router and do the verification again.

Post the complete value to the following command:
verify /md5 bootflash:isr4300-universalk9.16.03.07.SPA.bin 2199a0e3c7a01bcb2e399c46f4ce694d
