Update: This is actually a PS3 TOOL Firmware update.

Official $ony 1.60 PS3 Debug/TEST Update. This will currently NOT install on a retail PS3, and so it is intended for examination and comparison purposes only. We have 100% confirmed that running this updater on a retail PS3 will not damage it, however, it will give the following error before the installation completes: The data type is not supported.
