This can sometimes happen. The solution is to simply do the update again.
You can turn off the device by holding down the power button for 10-15 sec.
Once you are in step 4 of the update process, you can boot your ZERO in update mode using a power button combination:
- Press the power button 2x (consecutive, like a double click), and keep it pressed in the 2nd time until the red LED starts blinking.
- Then press the power button once more and keep it pressed in until the red LED stays on. This means you activated update mode.
You can also activate update mode with a power button combination
