[deleted] For those who have been struggling with restoring manual backups this might be helpful
I confirm, this workaround works in 2025.
I really do not like these silly GUI limitations of Android and GrapheneOS. I would love to have an access to obb and even data folders, even if I would have no root for other purposes.
The security that is destroyed by drag and drop is a joke, but the inconveniences for users are quite real.
A lot of apps would have be able to work offline with apk+obb setup (sometimes it's the only option possible, e.g. for preserved apps), but they do not due to these limitations.
