DCSD is an Apple Internal Mac application. When properly configured, the application serves as a diagnostic platform for Foxconn workers. The tool allows multiple devices to be connected at once.
The tool can boot devices into Inferno with a custom ramdisk that is personalized for the device. Inferno runs stress tests on the device and the results are stored in the DIAGS block.
DCSD reports results to a centralized server using a library called libInstantPudding.dylib. All production iPhones are to be run through DCSD for quality assurance. The DCSD app is also capable of installing demo bundles (via mobile backup restoration) for use in retail stores, and is also capable of installing apps. This app is required to connect to multiple internal servers in order for it to function properly.
The window's title includes the station name of the computer running the software (read from DCSD settings and a additional document for comparison / verification) The Open and View buttons at the top right of the window allows workers to open a new PurpleRestore document, and view the document's options, respectively.
Suprisingly, older versions of this app contain more features than the newer versions, particularly in the settings, where there are 3 more extra tabs and more options compared to the newer versions of this app.
Note: Leaked versions don't contain libInstantPudding.dylib, the necessary signed plist files, nor other files required for it to start, so the application forces the user to quit. It states an error, for example "failed to decrypt DCSD settings", with a red box and a OK button, which once pressed, will quit the application.
