Hi all 👋🏼
I have my pixel 7XL and I want change OS because now I have CalyxOS from grapheneOS. But I have only cubes I can install ?
Thank you advance

You can also flash GrapheneOS from another Android device, if you have one available. Phone-to-phone flashing is often more reliable.

I have successfully installed GrapheneOS from a Qubes OS debian-based VM. I used the CLI instructions.
