How to use the bootloader:

<ol>

<li>The list of firmwares should automatically be filled (make sure you have a network connection!)</li>

<li>Select a firmware (make sure you select the right one depending on which Crazyflie you want to update (CF1 or CF2))</li>

<li>Flash firmware (For Crazyflie 1, click on "Flash firmware" and switch on the Crazyflie during the next 10 seconds. For Crazyflie 2, press the ON/OFF switch of the Crazyflie longer than 1.5 second until one blue LED blinks. Then release the button and both blue LEDs should blink. Then click on "Flash firmware")</li>

<li>After a successful flash the Crazyflie will automatically restart in firmware mode and is ready to use.</li>

</ol>

It's nearly impossible to brick the Crazyflie. In case of any problems during flashing, you can always try again or use the PC client to re-flash.

* Photo/Media/Files: This is required to save the firmware files on the device.
