My Pixel 3 may be corrupted, can I recover anything before I factory reset it?
I just want a couple videos off the device, everything else is either backed up or recoverable.
The device currently can:
Stay locked after a reboot
Unlock for about 30-45 seconds before restarting and displaying the recovery screen I attached.
Boot into recovery/rescue mode (kinda, it shows the android mascot with a red warning icon and the text "no command", but I can't seem to mount it in windows or Linux
Is there any chance at all that I could get files off the device?
I'm not 100% certain, but I think Android encrypts your files by default if you have a screen lock set up. So if you turn the screen lock off, you should be able to get a readable filesystem off it from recovery.
The android thingy with "no command" is normal. Have you checked if it shows up in adb with adb devices?
Tried this for myself real quick, I can't get adb to open a shell due to SELinux, and adb ls /sdcard results in an empty directory, so looks like it is still protected.
I think you might need someone with some more expertise on this to help you, sorry
