Updates are distributed as signed zip files including a recovery, system, and userdata image. The current update packages are:

How to access the File System contained within an image
The Zip File is a simple matter to extract, however the images within them tack some massaging in order to explore. While they are a typical SquashFS File System, they have some padding bytes that prevented a simple "Unsquashing."
- It would be great if we could create a way to use dd to truncate the image instead of using a hex editor. You should be able ot somehow grep for the start and then dd the proper bits into a new file that could be explored correctly.*

The Boot Loader is included on the File System, currently in the X directory. The Boot Loader is based off of the Y Loader (More information can be found at Z). For the Sony BlueRay player, the Boot Loader is ABC.
