[Google Pixel 5a] Subrad5446@aol.com:
Hi there. My Pixel 5a has a motherboard issue, and needs to be returned to Google for warranty. I am trying to recover my files from the device before I send it in, but I'm having issues. For some reason, even though I have enabled usb debugging and issued commands through this laptop before, it says adb unauthorized when I issue the command "adb devices". So I downloaded my factory image, removed the "-w" from the flash all bat file, and attempted to flash to see if that would fix issue. However, it appears that for some reason I'm missing fastboot d. Here is the screen I get when attempting to flash.

And then it hangs there indefinately. The only way I can get out of here is by pressing the power and volume down simutaneously. Then the dialogue adds this line

fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.

Press any key to exit...

Can anyone help me get to a point where I can recover my data? Please, and thanks in advance.
