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:

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

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
