Updates

Vizio uses a custom update method, like on their TV's and Tablets. Specifically the updates are provided thru Update Logic (ULI), and are pulled from the ULI servers, then decrypted. After decryption, the box is booted into recovery, the update is verified (it's a normal CTV update at this point), then installed.
