SP Racing F3 EVO board:
In this video I explain how to flash an SPRacing F3 EVO board for brushed motors using the driver flasher program called Zadig. Some boards require a different type of driver to "talk" with the Betaflight/Cleanflight configurator and with this piece of software we can do the trick. The DFU mode stands for Device Firmware Upgrade and allows all devices to be restored from any state. It is essentially a mode where the BootROM can accept iBSS.
This method can be applied with any other board that requires updates via DFU.
Download the Zadig program on the following link:
