 ### Troubleshooting
 If you cannot flash the firmware:
-- Make sure you properly unlocked the chip
+- Make sure you properly [unlocked](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/How-to-Unlock-MCU-Flash) the chip
 - Make sure you don't have an already open connection to the chip in another software (st-link utility, ...)
 - Make sure you properly soldered the headers/wires, clean contact is mandatory
 - Also keep in mind the debugging header pinout can differ on some boards
+- In case you connected the pins and you get connection errors, make sure your ST-Link dongle pins are real, by sliding the plastic cover and checking on the ST-Link board itself. An example can be seen [here](https://youtu.be/XWh8yJ_p0HA?t=60)
