Cypher/FirmWareUpdate/Alternate
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 see if the driver is 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.
- Enable Full chip erase.
- Disable Manual baut 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.
