I’m using the install .bat file of a packaged build to install my game to Meta Quest 2 and had the same problem. I don’t know if that’s just a specific case but to anyone it may help:
- Had the device connected and also ready to use
- Ran the bat file and waited till the UnrealAndroidFileTool.exe part. (Installing new data…)
- When it reached to that point, I activated the device and tried to open the new installed app
- UnrealAndroidFileTool worked and installed the obb file!
I’m not sure how and why it didn’t work without doing this but I tried a few times and that seemed the only way.
