NOTICE: We've identified a bug with 1.7 that prevents it from starting up about 50% of the time. There will be an updated image released to fix this but in the meantime, you can try fixing it manually by following the instructions below.
1. Plug the Pi into a TV or monitor, plug in a USB keyboard, and then power it up.
2. Log into the Pi (Username pi, Password raspberry).
3. Type
cd ~/dreampi && git reset HEAD --hard && git pull -r and hit Enter.
4. Reboot the Pi.
Manual fix (Start with steps 1 & 2 above):1. Type
sudo pico /dreampi/dreampi.py and hit Enter.
2. Scroll down and find the line that says "def detect_device_and_speed(): MAX_SPEED = 57600" (it should be shortly after the green text starts).
3. Make a new line below it and add the following:
return ("ttyACM0", MAX_SPEED)
4. Press Ctrl + X, then Y when it asks if you want to save, and then Enter to save and close.
5. Reboot the Pi.
