I ran into a similar problem. I realized that the fastboot device is
different from the adb device. If you check your dmesg you'll see two
different vendor strings. Make sure you have both vendors in your
android udev rules:
SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", MODE="0666", GROUP="plugdev" # ZTE
Open
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", MODE="0666", GROUP="plugdev" # Google
device
And then restart udev (or reload it's configs).
