      # adb backup -apk -obb -shared -all -f ./current.ab

      adb prompts me to unlock the device with:

      Now unlock your device and confirm the backup operation...

      Device never prompts, backup never starts (55b ./current.ab is created)
      Do I need to reboot to bootloader first and do something I don't know what? (backup when in bootloader fails)

        @circ Developer mode is on yes? You granted access to the phone via the pop up box then sudo fastboot OEM unlock.
        But I thought nexus 5 was unlocked might be wrong though.

          @lakotaubp thanks, yes - OEM unlock was an install step.
          adb devices
          shows the N5

          I can do things like adb push myfile.txt /home/phablet/Downloads without issue

            so, here's some fun ->

            > adb version
            #Android Debug Bridge version 1.0.36
            #Revision 1:7.0.0+r33-2
            > adb backup -these are not any kind of acceptable params ....
            Now unlock your device and confirm the backup operation...
            >
            

            that adb backup cmd is verbatim...
            Where do I go to get help with this? I'm on pureOS (debian)

              ... and after a direct grab of the toolkit here : https://developer.android.com/studio/releases/platform-tools

              > ~/Downloads/src/platform-tools/adb version
              #Android Debug Bridge version 1.0.40
              #Version 4986621
              > ~/Downloads/src/platform-tools/adb backup totalgarbageandN0nS3nse
              Now unlock your device and confirm the backup operation...
              

              which is the same 'error'
              ..so, I'm guessing it's definitely a UBports / this particular phone/install related issue....

                If you want a full system back-up via ADB, you need to do it via recovery, not developer mode in the running OS.

                  thanks, yes - this is all happening in recovery mode :

                  > adb devices
                  List of devices attached
                  0b3a1eb703301be3	recovery

                    Ah, I don't think adb backup works with UT, because it's not an Android ROM, and that feature only works with Android.

                    You need to adb pull /data/*-data or something like that. I forget the exact command.
