Connecting a Pixel 9 pro to another Pixel 9 pro doesn't let me use the "file transfer" function because it's greyed out.
Also one pixel 9 pro doesnt even show USB options and because of that its not recognized in the bootloader interface and therefore I can't install GrapheneOS on it.
Connecting a different pixel 9 pro works so it doesn't seem to be a cable issue. Also connecting a USB to the affected pixel 9 pro and transferring files works as well and charging also works. I thought it's a software issue but its not even recognized in the bootloader interface. What's the issue here?
