In the event that something goes wrong during or after installing GrapheneOS, is there a way to roll back to your phone's original OS?
I'm interested in trying out GrapheneOS, but I want to make sure I have some protection against bricking my phone by accident, or at least have some protection against data loss.
I went looking over the official docs for GrapheneOS, but I couldn't find a guide on performing a backup on my phone (or any phone, really)- nor does Google themselves have a guide on this. I did a quick search in this subreddit and couldn't find anything either.
I'd like to take a full image of my phone's OS if possible, data and all, but worst case I'd like to be able to switch back to Pixel Android if necessary.
Is there a way to take a backup image of my phone or at least get a ROM of the original OS? For simplicity, I personally have a Pixel 10 (and got the phone for this explicit purpose, in fact!).
