| Symptom | Likely cause | Next step | |---------|--------------|------------| | Red light, motors spin then stop | Motor controller firmware mismatch | Flash an official 2.0 firmware from another healthy unit (extracted via USB). | | No USB enumeration, constant red LED | Bootloader corrupted | Hardware recovery via ST‑Link V2 (solder to SWD pads on PCB). | | Green LED but no tracking | Laser photodiode failure | The rescue cannot fix broken hardware.

This file seems specific to HTC devices, potentially those coded as "Lighthouse" or similar. If you've encountered issues with your HTC device and this file is provided as a solution, ensure you're obtaining it from a trusted source to avoid any malware or inappropriate modifications.
Before you begin, understand that while this process is generally safe, it involves low-level hardware re-flashing and carries a if not followed exactly. It should only be used on an already broken base station as a last resort.
While a solid red light usually indicates a physical motor failure, a blinking or flashing red light often points to a checksum error in the EEPROM firmware. lighthouse-tx-htc-2-0-calibration-rescue-244.bin
: Never initiate a firmware update if your controller or tracker battery is below 50%.
: Custom tracker boards built with the Lighthouse HDK display a red status LED indicating an initialization fault.

: In situations where the device's software or firmware becomes corrupted or otherwise non-functional, this file can be used to 'rescue' the device. By applying the calibration-rescue file, users can restore the device to a functional state, thereby minimizing downtime and the need for physical repair or replacement. | Symptom | Likely cause | Next step
When you plug in a base station, it performs an internal self-test. If the internal software detects an anomaly, it halts operation and flashes a red LED. This state is often referred to by the community as the "Red Light of Death" (RLOD). The error typically stems from two categories:
The lighthouse-tx-htc-2-0-calibration-rescue-244.bin is a vital tool for extending the lifecycle of SteamVR 2.0 tracking hardware. It represents the final software-tier intervention before a device is deemed a total hardware failure.
While a blinking red light can indicate a physical hardware failure—such as a broken laser diode or a seized motor after a drop—it is frequently caused by a . This usually happens during an over-the-air firmware update via Bluetooth in SteamVR, or due to a sudden power corruption that wipes the station’s calibration data.
