Flashing#
A Zap comes with firmware installed and updates itself over the air. Flash it over USB when it cannot.
- One Zap: use Flash firmware in your browser. It downloads the released images for you.
- A batch of devices: use the sequential flasher, a command-line tool that flashes one device after the other and records each serial number and public key.
