Hi @antinnit ,
Thanks for your guides both for 5.3 and 5.4.
I can package and deploy without any problems, however in 5.4. (where you now have to use Vulkan) the application crashes on the quest with a null pointer dereference located in the vulkan classes. You cannot even disable Vulkan any longer. I have reproduced the same crash on the application built / deployed to the quest from two different workstations. I do not think I am the only one, though it may have not been reported that much.
Here is the crash log (obtained through the device logs from the Meta Quest Developer Hub):

UE 5.4.4 will fail unless you have SDK API Level set to “latest”
SDK API Level (specific version, ‘latest’, or ‘matchndk’ - see tooltip)
Internal Name: SDKAPILevel
latest
All you need to do is update the SDK versions under: Project Settings/Platforms/Android/Target SDK version to 34 and change Project Settings/Platform/Android/SDK API Level to android-34. This is a requirement from the Meta Store.
It won’t fail if you have the versions set correctly(its better for build control). Unreal 5.4.4 updated the android sdk to version to 34 (finally), so we need to change the versions to reflect that.
Thanks for the helpful post. I follow the steps and it worked. I was able to install the basic VR Template on my Quest 3. Next I will test adding custom items

I have made modifications to the Unreal Engine Android Project settings for Distribution (shipping), and provided guidance on packaging and uploading to Meta Quest Hub / App Distribution.

Oh man, thank you so much! I spent 8 hours with those NDK/JDK/SDK etc. issues, but your guide finally made it packaged and installed. Awesome work!

Followed all the instructions. I can now build, package and deploy. But when I run just the original, unmodified VR template app, it looks like the attached. Anyone else experience this? The colors are all corrupt and are completely green. The skybox is ok, though.
Any ideas on how to fix?
