# Flashing the first time
Disassemble the case so you have access to each Pro Micro. Flash each half with QMK Toolbox by connecting the USB cable and shorting RST and GND. After that, just use the soft reset key on your respective layout to reflash both halves.
# Reflashing Animus
Reflashing the stock firmware is pretty easy. Just follow the same steps in the [original guide](https://imgur.com/a/8UapN). You will have to manually reset the Pro Micro (by shorting the GND and RST) during the upload step. Then reapply your keymap through Arbites.
