: For devices with S-ON (Security On), you can only flash an RUU that is the same version or newer than your current firmware; downgrading usually requires S-OFF .

If the RUU process is interrupted (e.g., USB disconnection, PC crash) during the flashing of the bootloader ( hboot.img ), the device can be "hard bricked." In this state, the device will not turn on and often requires a specialized hardware box (JTAG) or SD card flashing techniques to revive.

The RUU will guide you through the update process with on-screen instructions. These may include agreeing to terms, selecting your device, and confirming the update.
