 Now that you have gone through the basics of what you can do with the board you can explore the endless possibilities it provides by checking exciting projects on ProjectHub **[5]**, the Arduino® Library Reference **[6]** and the online store **[7]** where you will be able to complement your board with sensors, actuators and more.
 
 ### Board Recovery
-All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double-tapping the reset button right after power up.
+All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by configuring DIP switches.

+***Note: A compatible carrier board with DIP switches (e.g. Portenta Max Carrier or Portenta Breakout) is required to enable bootloader mode. Bootloader cannot be reached with the Portenta X8 alone.***
