Here's how I performed the upgrade:

Downgrade from the stock P003AM30 to POS30203

Upgrade to version 5.1 (first signed binary firmware)

Upgrade to version 7.1 * (most recent version? maybe 7.4?)

* When upgrading to 7.1 there is a typo in the OS79XX file, it will say
"P00xxxxx" change it to "P0Sxxxxx"....great typo by Cisco.
