By this process you will be able to flash firmware in your bricked flight controller.
BetaFlight CleanFlight iNav not connecting problem solved.
In this video I fixed my bricked SPRACING F3 flight controller.

Thank you, kind sir! I failed to program my controller using Betaflight flasher, and you really saved me. All the best to you!

Excellent tutorial. By following your directions I have been able to configure an disused NAZE 32 with Betaflight that I thought I had "bricked".

Tried flashing with a new firmware. Flight controller will no long communicate with pc. Have all drivers. Zadig ImpulseRc Driver fixer. Even bought an ST-Link v2 and tried using the utility to flash. But it will not communicate with PC. Any ideas how to flash with st-link? Connected with camera and receiver and all and everything shows up in goggles. Just won’t communicate with the pc.

If you have done everything in this video, updating and installing drivers, unselect "No Reboot Sequence." I was having the same issue with my Vortex Mojo 230 and realized that this option is only valid if you have a setup that needs to be in BOOT MODE. Not all FC have bootloader pins or a button as the Mojo 230 connects to Betaflight without needing to do any extra steps, just plug the kwad straight to the computer and unselect "No Reboot Sequence."

I have a Omnibus f4 v5. I get a solid green light when I plug in usb and there is no sound of connection. For me I flashed the wrong firmware. I flashed Omnibus instead of Omnibus SD. What should I do is this something I can fix??? … Zadig doesnt even see the stem3 driver. and beta flight doesnt even detect any com ports. I have tryed just about everything. its like the usb connection is not detectable. did me flashing the wrong firmware screw up my omnibus f4 v5 ?? do I need to buy another?

STM32 timed out programming : failed
How can I correct this

[duelz]

Hi, when I click next in flash loader demonstrator it gives me an error that says, "No response from the target, the Boot loader can not be started."
I have shortened the boot pins and downloaded all the drivers. I dont know what to do this is really frustrating.
Any help would be appreciated 😅

[pak]

I have a NAZE32 V6 and I do not know where to ground the pins as you showed on your video. Please help.

[tomconnors]

Didn't help at all really, I'm still stuck here with a FC that wont come out off boot mode, tried what was in the video however it wont even detect the board in that software shown, I'm about to throw in the towel, any further suggestions?

[Sicemong]

I have a problem because i install different drivers not STM32 and now my keyboard is not working, can you help me please?

[dominickeen]

Thanks a lot none of my spracing f3 would work trying this as soon as i get home

[otoe]

When I try to choose a com port(com1 always shows up but nothing else) in the Flasher Demonstrator, it says that it is unable to use that come port. Any help???

[israellavi]

Thanks, I was able to flash the sp F3 card. But still can not connect to it using betaflight.
When trying to connect using betaflight I see "Serial port successfully opened with ID: 13" but it does not show the FC details.
I'm using windows 10
