I can't install GrapheneOS onto my Google Pixel 8 Pro, could someone with strong Kung-Fu help?

    Sart surely, if you provide us with some info why it's not working and what you have tried so far.

    Sart Generally, for people who are not by your side and so cannot see what you are doing, it's necessary to have a description of the problem. Such as:

    • Are you using the web installer or the commandline installer?
    • Which device, operating system and (if applicable) web browser are you installing GrapheneOS from?
    • A description of what you have tried so far
    • A description of what goes wrong, including any error messages that may be displayed

    I have eventually set my phone in the 'unlocked' state in Fastboot Mode, my phone is connected via USB. the settings on my phone are USB Debugging enabled, OEM is set permanently onto 'enabled' there is no way to turn it on/off; in the phones 'USB settings' I have it set to 'This phone & Transferring files', I have also installed the 'Flashing as non-root' packeage. So, I think my phone is ready for the 'UNLOCK BOOTLOADER' step on the GrapheneOS Web installer but when i press the blue button I get a message "Error: Failed to execute 'open' on 'USBDevice': Access denied."

    Is there anyone out there with Superpowers that can help?

      The other strange thing that happens is: I press the blue button 'UNLOCK BOOTLOADER' a blank screen appears that wants to connect to the phone but cannot find one so I remove the USB 'c' connector and replace it and then my phone will appear on the list but as soon as I click on it to connect that window disappears completely and I get the same "Error: Failed to execute 'open' on 'USBDevice': Access denied." in red text.

      yes, I typed in the 'fwupd' command but no difference.

      well, then I can only assume that it's either a browser issue, bad cable or you didn't enter fastboot correctly. What is your fastboot screen showing (menu)?

      Sart If you can't disable OEM unlocking then you cannot install GOS, its required, there is no work around to install GOS without this disabled.

      Is your phone an unlocked variant, or a carrier, like Verizon

        Sart "Error: Failed to execute 'open' on 'USBDevice': Access denied."

        This means either that the OS is not configured to allow the browser to access USB or the browser is not configured to allow the installer app to access USB.

        raccoondad wouldn't it be the other way around that OEM unlocking cannot be enabled? I always thought that toggle would be greyed out if it was carrier locked.

        Sart I am using Ubuntu ver 24.04 and Brave browser.

        Browser features such as private/incognito and Brave Shields interfere with the web installer.

        OME unlocking is permanently dissabled.

        Sart OEM is set permanently onto 'enabled' there is no way to turn it on/off

        Can you provide a picture of that?

        Sart have you connected the phone to the internet before? It needs to be online once to enable OEM unlocking (assuming it's a completely fresh phone out of the box)

          I tried to attach a photo of the Fastboot screen, cant do it at the moment.

          so:

          (this is all in the lower 1/3 of the screen)

          Red triangle on top with a black exclamation mark in it.
          (then)

            Sart Then its not possible to install GOS, apologies. If its unlocked/not a carrier version you can connect it to a wifi network and see if that works, but otherwise you cannot install GOS. We cannot help you install GOS until this is done, and if its a carrier version that prevents OEM unlocking, we cannot help you at all.

              no phone not new and I will put a sim in the phone and connect to my laptop to check the internet. At the moment I have 2 phones connected to my laptop (no home internet), 1 phone (Samsung s8) is set up as a 'hotspot' my other phone is the target phone (Pixel 8 Pro).
