Quest 2 - Unity - Issue with OVR Scene Quick Preview

Hello,

I am trying to run the OVR Scene Quick Preview on the Quest 2 for my Unity game. While it works perfectly on Quest 1, on Quest 2 this is what happens:

1) Build and Deploy App works fine, it runs the OVR Transition Scene on Quest 2 (Black screen with floating white windows saying "Failed to Get Scene Info Data"
2) When I try to do Build And Deploy Scenes, I get this error:

Log
Building and deploying transition APK  . . . Success!
Building scene bundles . . . 
Deploying scene bundles to device . . . 
Failed!
adb: error: failed to stat remote object '/sdcard/Android/data/com.my.vrgame/cache/scenes/OVRMasterBundle': No such file or directory

and it doesn't run.

I have allowed for the data permission on Quest 2. Suggestions?

    i figured it out. The original quest was built of of a version of Android 7.1, but the Quest 2 is Android 10, which requires API Level 29. After updating my API I was able to successfully load an apk

    I have realized that the correct APK allows me to Build and Run, but the whole Test Scene loading still fails. Oopsies

    I am having the same issue ....
    Deploying scene bundles to device . . . 
    Failed!
    adb: error: failed to stat remote object '/sdcard/Android/data/com.VP.newvrgame/cache/scenes/OVRMasterBundle': No such file or directory

    I asked Oculus support ... no solutions from them.  I sent it as "Report a Bug" in ODH, no response yet. 
    I have tried making changes to OVRBundleManager.cs and OVRBundleTool.cs  I have transferred files from OVRAssetBundles and OVRTransitionscene.unity to Quest2.  Tried API level 28, 29 and 30. Tried the regular Build and Run in "File" instead of OVR Scene Quick Review.  NO luck yet.

    Seriously, anyone in Oculus aka Facebook trying to get a solution for us? Who else to ask?    What else can we do?

    I finally took the following steps and made it deploy to my VR headset since both OVR Build APK and Run as well as OVR Scene Quick Review did not work for me on Quest 2.
    1. In Unity: File - Build Settings - Export Project - Export - by saving in a folder.  It builds a Gradle project in that folder
    2. In Android Studio: import the Gradle project pointing to the folder above
    3. In Android Studio: while keeping the VR device connected to the computer, Build - Build APK. After that is complete then Hit the play button next to the device - It goes thru' Gradle Build Running
    4.  Go to your VR device and it should show up in Applications - Unknown sources.
     Good Luck.

    Please help us with this, Oculus. The radio silence is deafening.

    Are others who experience this issue on windows insider rings? 

    I'm close to trying a complete Windows install to try and fix this issue.

    I found the issue!

    In Assets/Oculus/VR/Editor/OVRBundleManager.cs, on line 453 it detects that no bundle has been previously deployed by comparing the error message to the string "does not exist". But as reported in the OP the error message is "No such file or directory".

    I changed line 453 to instead read:
    if (output.Contains("does not exist") || output.Contains("No such file or directory"))

    And now it works!

      This worked for me, for both the "OVR Scene Quick Preview" and ADB problems. Give him some praise. Thank you Anonymous

      If the issue is resolved for you, for the next step, you might want to open the ASSETS>Oculus>VR>Scenes>controllerModels.unity from you project manager (inside unity) it show the controller (without hand)
