SteamVR-Dongle-Flash

A simple Guide and batch script to flash steam controller dongles to watchman dongles for SteamVR/OpenVR

Tested and Working

A steamVR controller Dongle purchasable on ~~Steam~~
- alternative dongle I haven't tried but should work, since dongle no longer purchaseable from steam.
- alternative dongle 2 Just Vive Dongles sold by 3rd party.
SteamVR installed on your computer

Please Assume this change is permanent
This will flash ALL CONNECTED dongles, remove any before hand that you don't want flashed.

Remove ALL SteamVR dongles, including the HMD.
Exit Steam
Plug in your Steam Controller Dongle to a USB.
open a Command Prompt (cmd or power shell)
Navigate to where SteamVR app is installed on your computer (default is: C:\Program Files (x86)\Steam\steamapps\common\SteamVR)
- Powershell CMD - cd 'C:\Program Files (x86)\Steam\steamapps\common\SteamVR'
Run the Command tools\lighthouse\bin\win32\lighthouse_watchman_update.exe -D tools\lighthouse\firmware\vr_controller\archive\htc_vrc_dongle_1461100729_2016_04_19.bin
Restart Steam, plug your dongles in, close the command prompt/powershell and you should be good to go!

You should be able to flash multiple dongles at once, and not need to remove old ones, but as general precaution I advise against it.
This should be considered permanent In theory its not but I can't seem to find anyone who has successfully flashed firmware back, and my own attempts are unsuccssful.
There is a firmware that will Permanatly change the dongle, but you must be signed up for the SteamVR HDK Directions on how to do so can be found here

The Batch File is designed as a one click solution to do it for you.
- NOTE the batch file only works if Steam and SteamVR are installed to default directories in the C: drive.
