Oh! Wow, OK, thank you.
But just so I am clear, does it prompt me for a URL or ...? How does it know I want Graphene just by connecting my phone to my PC and opening my browser? Was I supposed to go to some specific page as part of the preparation?
Again, I feel like I must be missing a step here, and I want be sure I wasn't supposed to do something prior to this step to make that work, in other words. Thanks for the help,
(FYI, I have not yet done the Unlock Bootloader step. Maybe that's why I am not seeing a Download release option in the Fastboot menu?)
