I tried to connect but failed. Then I press and hold the volume + and power keys to reboot and unplug the USB cable at the same time, then I shut down, press and hold the volume keys + and -, and then plug in the USB cable, and I get the above error

You need an da.auth file, you probably have DAA enabled, but it's not in the provided snippet of logs, so there isn't much folks can help you with. Please try to provide more info.
