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?

Didn't work bro. Fc doesnot connect with beta or cleanflight. What can I do?

[@MrAl28111]

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

[@MakerHand]

Glad it helped

[@Aar0n2009]

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.

[@MakerHand]

unplug the module which connected to UART1 then connect

[@tomconnors7236]

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?

[@ejayasaula]

I turn off UART 1 and now can't connect to betaflight 😭 help!!

[@MakerHand]

Try to do the same like the video, it will reset the FC

[@ejayasaula]

MakerHand thanks man fixed!

[@israellavi2904]

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

[@bigboitoys1451]

Israel Lavi I'm having the same issue does your red light come on when you plug it in or does the blue only illuminate?

[@jrautomopeddrone2221]

Did you solve this issue? I have exactly the same problem.

[@Blackazza]

try cleanflight

[@hendrikdjaja4152]

Im sorry if this is Out Of Topic, I was stressed out: My board FC CrazybeeF3 BNF Frysky, my latest firmware : betaflight_3.3.3_crazybeeF3FR (Stable) on configurator tab : I choose : SPI_Rx Support then.. I accidently choosing wrong SPI Reciever Provider to A7105_Flysky_2A and save it now my FC can not connect to USB anymore, everytime connect it is says " Unkown USB device (Device descriptor request Failed) for windows 10" is there any suggestions to fix it? please help me anyone..

[@MakerHand]

Try to re flash it by the boot button or use the same method used in this video i think it will be work

[@jannpe1003]

when click in the demonstrator the first time next I get "No response from the target, the Boot loader can not be started. Please, verify the boot mode configuration abd the flash protection status, reste your device then try again." My FC is showning only one solid blue light so it should be in Bootloader mode. Can someone help me??

[@MakerHand]

Did you install cp210 software?? I think your boot pins are not shot properly

[@prozay6856]

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."

[@MakerHand]

"No Reboot Sequence" it didn't worked for me

[@prozay6856]

MakerHand didn’t understand your message. Did it work or it didn’t? Not all setups need to have that option highlighted, or selected.

[@MakerHand]

@@prozay6856 In my case it happen only by manually flashing the firmware

[@Sicemong33]

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

You can use virtual keyboard

[@duelz9366]

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 😅

[@RealHiipixel]

Have you solved the issue? I'm getting similar but on my case, it also says "Unrecognised USB Device"

unplug your FC then plug in your boot pins. Plug back in your power cable and then remove your boot pin. Now try.... This fixed it for me, i wish you the best of luck.
