Please forgive a new user. I just got a Pixel 8. OEM unlocked. I was able to get in to the developer options and enable OEM unlocking. I was able to press volume down and start which allowed me into the Fastboot Mode menu. I then connected a USB cable from my laptop running Kubuntu latest. Following the directions on the install page, I installed android-sdk. I then, according to the instructions ran this command sudo systemctl stop fwupd.service. I then plugged in the usb cable to my laptop. Using Chromium, and Brave, I clicked on Unlock Bootloader. A window popped up and I could see my Pixel 8, which I chose. I get the following error message... Error: Failed to execute 'open' on 'USBDevice': Access denied.
That;s as far as I have been able to proceed. Any help for a new user would be greatly appreciated. Thank you!
