In general there is a difference between:
- I have followed the directions on the GrapheneOS web site and I am still stuck (this can happen!), versus
- I have tried things based on what I used to do when I was running LineageOS back in 2008, or based on something I saw on TikTok.
If the GrapheneOS web site needs to be improved, it can be improved. It is not clear it is possible to improve TikTok.
