Downloading the factory image to a second mobile keeps failing. I have it on a pc—is there a place I can copy it to on another mobile that I'm using to install Graphene OS? A web page suggests /storage/emulated/0/Download/ but I haven't found any such filepath on the second mobile. I'm presuming the install process needs to use expected files at expected locations? Can I just unzip to, say, the Downloads folder on Android and run a file or command?
