alwayslearning You can try starting from the beginning again. To be safe, you can close out all browser tabs, close all programs, even restart your computer first to make sure no other programs/websites are trying to connect to the phone. After restarting the flashing process, make sure you don't touch or move the phone until flashing is complete. Expect the phone to restart multiple times.
Need help! Error: Failed to execute 'requestDevice' on 'USB': No device selected
alwayslearning if you're on Windows, also make sure you installed the fastboot drivers.
other8026 Will do.
fid02 Am using a mac
other8026 Have done that. But the computer doesn't see the phone "Graphene wants to connect [but] no compatible device found. I've connected with the pixrel8pro usb cable BTW.
alwayslearning you can try some of the following:
- make sure you're using the USB-C port on your computer if possible
- try a different port
- restart the computer and try again
- make sure your phone is in Fastboot mode (if you see Fastbootd, you're in the wrong place)
- try another cable if you have another high quality one
other8026 Thanks for those steps. I will try each one and let you know how I go.
other8026 Okay. I have:
- Confirmed using USB-C ports (only ones on the macair laptop)
- Tried both (USB-C) ports
- Restarted the computer and tried again
- Not sure what Fastboot mode is. But I didn't see 'Fastbootd' at all
- Tried another quality cable.
And nothing changes. For some reason, the phone is not being recognised.
All I get is: the triangle alert symbol above "The bootloader is unlocked and software integrity cannot be guaranteed. Any data stored...etc....." [Then, below that] "Visit this link on another device: g.co/ABH ..."
The phone then cycles through to a white screen with 'google' in the middle of it. Then, to a black screen. And it keeps cycling, 15 seconds or so each, until the battery goes flat. In the first bootloader page, I have pressed the "Press power to pause" and it stays on this page until it goes flat. Leaving the phone on the charger leaves it to get quite warm as it constantly stays on.
alwayslearning Which version of macOS, which version of which browser?
Did you try to do it from different browsers? For me installation worked only from Google Chrome.
de0u Mac Sonoma v14.5. And Chrome version 126.0.6478.127 (arm64).
RandomlyGeneratedName1 Yes, I followed the Graphene OS instructions. So have only used Chrome. And I made sure to update the OS on the new phone, and the laptop. And also updated Chrome.

How about:
- Pause the bootloader
- Unplug the phone
- Quit the browser (maybe reboot)
- Restart the browser and the installer
- Plug the phone in
If none of that works, does Google's online flasher for their Pixel OS work?
de0u Great suggestions. Thank you. I will give them a go - and if needed - Google's online flasher. Thank you!
Sigh...
- Paused the bootloader - check
- Unplugged the phone - check
- Quit Chrome browser and rebooted - check
- Restarted browser and installer - check
Plugged the phone in - check - Opened google's flasher for Pixel OS - check.
Again, this flasher does not recognise there is a device attached.
Removed one end of the cable and restarted Chrome & google flasher. Repeated at the other end. And then a different USB-C port on the laptop (there's only 2). Switched with another good cable (New Pixel cable and another good quality cable.
Nothing seems to make any difference to the phones behaviour and it continues to not be recognised.
I see that the google flasher site has some code instructions (nothing that I saw for apple osx though). I do have an old android phone and also a pc that runs linux, if that helps. Not the most confident with coding but have done a little bit once or twice. A new and very expensive phone that refuses to work is a bit nerve wracking. So I am keen for any further help (Thanks for being so kind as to help in working out this puzzling situation).

What kind of Linux?
Trying one or the other of those seems timely.

Not familiar with Mac but double check on the phone developer option is enabled, USB debugging is enabled, select the option for no timeout on debugging notification in case you missed it on the phone also OEM unlocked enabled, watch for the onscreen notification allowing USB debugging. On your computer, if you're running anything like uBlock or or any other extensions like these make sure they allow from graphene website or turn them off temporarily.
Ducter As far as I understand the installer, USB debugging is completely not a requirement for installing, and is a good thing to have turned off the rest of the time, unless one is actually connecting the device up to a debugger. USB debugging is recommended in various YouTube videos but not, as far as I'm aware, in any official GrapheneOS documentation.
