Unlike A3 and Motorola Edge devices, the Snapdragon Spaces Services for Think Reality VRX cannot simply be installed or uninstalled via adb. The version of the Services is determined by the Software Version (Firmware Version) installed on the VRX device. 

When trying to install the Spaces Services regardless, the process will seem successful at first glance but not take effect.
