Recovery Firmware Update (using boot pins)

Note: Before trying recovery, close all apps and restart your PC and try the normal procedure on the Firmware Update Page again.

Note: We do not use, and do not recommend the use of the Zadig driver program mentioned by BetaFlight. We have seen poor results when used.

Note: As usual, you will need the CP210x Drivers installed as found on the BF Welcome Screen.

Note: You can use the Windows Device Manager to confirm the driver is installed correctly and connected and what Com port is in use by the CP210x (FlexF3).

Note: if you are not successful, REBOOT the PC and/or try a DIFFERENT PC. These two points have solved most failed update cases.

If you have lost communication with your board follow these steps to restore communication using the Windows Betaflight Configurator:

• Power off, Disconnect FLEXF3 from USB Cable
• Enable No reboot sequence.
• Enable Flash on Connect.
  

  Boot Pins
• Enable Full chip erase.
• Disable Manual baud rate.
• Jumper (short) the BOOT pins.
• Press the Load Firmware [Local] button at the bottom right.
• Select the *.hex file from the location you stored it in prep.
• Connect USB Cable to FLEXF3 (activity LED will NOT flash if done correctly). The Flash update should start automatically. Wait for it to complete.
• Remove BOOT jumper. Remove USB cable.
• Power on by USB cable (activity LED should flash).
• Connect normally and Update Settings.
