[Lock3rz]

hi. there.

i want to use Gear VR with SteamVR throu vridge 2.0

i use Msi Laptop

8GB RAM
GTX 970M
512GB SSD
GearVR 2017 with Controller
Galaxy S7 Edge

but, in steamVR, i can not run 'Room Setup' which is nessarary for running SteamVR.

when i clicked 'Run Room Setup' once nothing popup.
normally, setting pop up comes up so i can choose room scale or standing. right? but, there is no popup comes. even after waiting 30minutes...
so i click 'Run Room Setup' once again, there are error message comes : 'SteamVR Room Setup - VRApplicationError_LauchFailed.'

in GearVR, i can show white Dom-like atmosphere when i clicked 'Run Room Setup'
and i can see my gear VR Controller works as ViVE Controller in that atmosphere.

i can see and use SteamVR HOME, but i can't use SteamVR tutorial which plays Left Sound and unresponse and SteamVR Media Center. both come with popup, but unresponse.

i guess it's not VRidge problem, But i have no clue to solve it...

can you help me?

ps.
i did these :
Uninstall Graphic Drivers with DDU, install latest Graphic Drivers. - not works
Uninstall and Reinstall SteamVR - not works
enable Fake Sensor on VRidge - not works

Well how are you using DDU?
Most people have no idea how to use it correctly and then often say it just did not work for them due to this scenario. Please use it like this > https://steamcommunity.com/groups/Master_Race_Geeks/discussions/0/1621724915801469252


How to play Steam Games with GearVR

Since you are on a Laptop; first go and download these 3x Driver Suites first.
> Intel Chipset INF[downloadcenter.intel.com]
> Intel Iris Pro Graphics 580[downloadcenter.intel.com]
> NVIDIA GeForce Mobile 900M series[www.nvidia.com]

This way you have the driver packages already downloaded and ready to install. But do not install just yet...

Now run the DDU App and change the Options as shown in the IMGUR picture based guide in the 1st link above at the start of this post from the MasterRaceGeeks group.

Once in Windows Safe Mode, wait for DDU to popup, it will, just give it a moment.

Then select INTEL > Clean but do not Restart
when cleaning is done, select NVIDIA > clean but do not restart.

When all done, exit DDU app, then Restart Windows normally.

*Once back in normal Windows, make sure the LAN/WIFI gets disabled temporarily for the rest of this period. This avoids Windows Updates from stepping in right away. Then proceed with the above driver installs, in the order I listed them, when one finishes, Restart Windows, do the next driver install, and so-on until all 3 are fully install successfully. Reboot after the NVIDIA one as well at the end, because Drivers and Software of this kind in relation to hardware controlling; may not function properly or fully until after rebooting.
