My screen is stuck on Fastboot Mode. Device state is "unlocked".
a) Months ago, when I tried this, it started very smoothly. I was able to unlock the bootlooder, select my phone when you get the popup "grapheneos.org wants to connect". I started the "Download Release" under 'Obtaining Factory Images without problem. Then partway during the flashing process, I got the message "Error: The requested file could not be read, typically due to permission problems that have occurred after a reference to a file was acquired." Here I got stuck. When I tried to start from the beginning of the process it said the phone was already unlocked and then this time I would get 'error undefined' when I tried to obtain factory images.
b) Kept my phone connected to the computer for a few hours or days (can't remember at this point) and then the internet got disconnected at one point, and after that, my phone wouldn't show up to pick. I found online sometimes people said the cable is the issue, so I've tried 5 or 6 different ones. Now I can't get my phone to even show up at all to choose to connect to (even going back to the original cable I had part success with).
c) I've tried on Windows 10 with Google Chrome, Windows 11 with Microsoft Edge, and a really old Mac. My phone no longer shows up. I keep getting the message "No compatible devices found." My phone is still unlocked in Fastboot mode.
(I will add I can't get the phone to show up as connected at all on my computer anymore)
I feel really foolish for trying this and have gone months without a phone now. Someone please help!
