Summary
This (hidden) application is usually accessed by powering off the device, then after plugging in a charger, and holding down the volume up button and the home button. On iPhones and on iPads without the physical home button, it can be loaded by pressing and holding the volume up and down buttons at the same time while plugging in the charger. It is present on all iOS 10.3 and newer devices. Apple uses this environment to boot to System Configuration, part of Self Service Repair.
It looks to be sending data to https://idiagnostics.apple.com, however due to certificate pinning, the data being sent is unknown. It is known to connect to AST2, an internal diagnostics web app, for diagnostics.
Other Information
- It may be worth noting that the time displayed at the top-left (in the case of an iDevice without Airplane Mode) of the screen is Pacific Standard Time, regardless of user preferences.
- When opened in any way except from the volume up method, the app crashes to the homescreen, probably because the environment is not setup correctly.
Localization strings
Extracting its English localization strings yields these:
