This tool aims to automate the rooting process described in Rooting the Xiaomi STYJ02YM (viomi-v7) Vacuum Robot.

It is known to work with the following models:

• Mijia STYJ02YM (viomi-v7)
• Mijia STYTJ02YM (viomi-v8) (experimental, needs manual update of Valetudo)

• a linux machine with bash, ssh, wget, adb and sha256sum
• the robot is already connected to your wifi (if you don't want to use the xiaomi app to do this, you can do this with python-miio
• the linux machine needs to be on the same network as the robot
• a micro-USB cable plugged into the robot’s micro-USB port.

Clone this repository, then run the following command and follow its instructions:

./viomi-root.sh

1. Enable the adb shell command.
2. Temporarily disable robot services to allow the adb bridge to persist during setup.
3. Install dropbear along with your ~/.ssh/id_rsa.pub public key
4. (Optionally:) Install Valetudo.

Problem: No adb connection is established.

• Check that adb and your cable is working in general by connecting to an android phone (enable usb debugging on it), e.g. by using adb shell.

• Check the dmesg output to see if your computer ever recognized a USB devices. Some machines are too slow, some USB stacks flaky. People have reported success with a raspberry pi when their main computer didn’t work.

• If you see a message like:

  adb: insufficient permissions for device
  See [http://developer.android.com/tools/device.html] for more information
  

  Follow the link for advice, in particular make sure that you are a member of the plugdev group and have setup correct udev rules (dmesg would probably show you the device ids).

• Finally, this may not be working on first attempt, but may need multiple tries, but typically not more than 10.

Problem: The script was not able to establish a ssh connection and didn't finish.

Solution: Rerun the remaining steps of the script (replace ROBOT_IP with the actual ip address)

./viomi-root.sh change_password
./viomi-root.sh restore_robot_services
./viomi-root.sh install_valetudo ROBOT_IP

Problem: An old Valetudo version is installed that doesn't support viomi.vacuum.v8 yet.

Solution: Manually update your installed version by uninstalling and then reinstalling. See also rumpeltux#11
