Unscrew the four screws securing the bottom part of Vizy's case. The Vizy screwdriver has the proper size phillips bit for this and it's recommended for use to avoid stripping the screw heads.
Carefully remove the microSD card

Prepare your microSD card to connect with your computer, and open your preferred Imaging Software. The RaspberryPi Imager is made to work with RaspberryPis, the micro-computer running Vizy, and has its own 'how-to' which might be helpful. Run the Imager, select 'Custom OS' to locate the Vizy Image file downloaded in step 1, and select the microSD as the storage target. Once the image is finished writing, continue to the next step.

Reinsert the microSD to Vizy and power-on! You should be able to connect to an older version of Vizy using 'vizy.local' in your browser. The last step is to Update Vizy.
A wired connection is recommended when updating Vizy as it is the most reliable and strongest connection.
