The Model S has two levels of reset. A frozen unit is cleared by holding POWER to force it off and booting again. To rebuild a misbehaving system, re-run the latest TrimuiUpdateV*.zip or an official Trimui_Factory_Recovery_model_S package from the on-device Files browser. A full low-level restore uses the PC tool PhoenixSuit: with the device off and the SD card removed, connect USB-C and hold L + R while powering on to enter USB recovery, then flash the official recovery image. This rewrites internal storage, so back up anything important first.

FAQ

How do I restart a frozen Model S?
Hold POWER until the screen turns off, then press POWER again to boot. No data is lost by a simple power cycle.
Is there a one-button factory reset?
There is no single in-menu factory-reset combo. Use the official Trimui_Factory_Recovery_model_S package from the file browser, or PhoenixSuit on a PC (hold L + R on boot over USB-C) for a full restore.
