Yes, but I don’t know if it works with grapheneos. You can live-boot an image with fastboot boot boot.img. You need the grapheneos img file obviously, and a working fastboot connection, and an unlocked bootloader. Usually unlocking the bootloader means wiping the device before you can do anything else though.
If you have a pixel, grapheneos should work just fine. Except adding payment cards to Google wallet (non-payment cards and digital tickets work fine though). Some apps may refuse to work on uncertified devices. RCS support depends on your carrier. Outside of those things, though, literally everything else I’ve done has worked.
Is it possible to try Graphene out, like dual booting on PCs? Without throwing the existing Android setup away or bricking it?
