The filename breaks down into meaningful parts:

Unlike typical SteamVR base station firmware (.bin files updated via Bluetooth or USB), this file is not meant for normal updating. It bypasses version checks and directly writes to the station’s STM32 microcontroller and the laser motor controller. lighthouse-tx-htc-2-0-calibration-rescue-244.bin

Observe the LED sequence:

  • Inspect header:
  • Backup partition (fastboot example):
  • Flash:
  • Readback verify:

    • You will use a command‑line tool like dfu-util or the more common STM32CubeProgrammer (CLI version). For simplicity, use dfu-util: The filename breaks down into meaningful parts:

    dfu-util -a 0 -s 0x08000000:leave -D lighthouse-tx-htc-2-0-calibration-rescue-244.bin

    If using STM32_FlashLoader.exe (older tool): Unlike typical SteamVR base station firmware (
