ImpulseRC Driver Fixer

When flashing/connecting for the first time, the default driver setup on your Windows machine may be incorrect. The ImpulseRC Driver Fixer tool can quickly and easily fix the drivers, and even automatically put your FC into DFU mode to flash directly if you're having issues.

It can be downloaded at the link below:

fallow mica Jun 25, 2024, 2:02 PM

#

What happens when you run it?

ruby heart Jun 25, 2024, 2:03 PM

#

it says its installing the dfu driver

fallow mica Jun 25, 2024, 2:04 PM

#

That's good.... please let me know what happens when it finishes.

ruby heart Jun 25, 2024, 2:04 PM

#

it says all drivers fixed

fallow mica Jun 25, 2024, 2:04 PM

#

OK, try the firmware flash again now.

ruby heart Jun 25, 2024, 2:05 PM

#

still says failed

#

im in dfu bootloader but betaflight can somehow not enter my fc to flash

fallow mica Jun 25, 2024, 2:06 PM

#

OK, so is the flight controller connected to Betaflight in DFU mode?

ruby heart Jun 25, 2024, 2:06 PM

#

yes

fallow mica Jun 25, 2024, 2:06 PM

#

But when you click the flash button it cannot flash because it says it cannot connect?

#

Can you please try the "no reboot" option on the firmware flasher too?

ruby heart Jun 25, 2024, 2:07 PM

#

thats what im getting (the red text) its in german so dont wonder

ruby heart Jun 25, 2024, 2:07 PM

#

fallow mica Can you please try the "no reboot" option on the firmware flasher too?

i have it on

fallow mica Jun 25, 2024, 2:07 PM

#

And you have tried if off, right?

ruby heart Jun 25, 2024, 2:08 PM

#

yea

fallow mica Jun 25, 2024, 2:08 PM

#

(you tried no-reboot on and off?)

ruby heart Jun 25, 2024, 2:08 PM

#

yes

fallow mica Jun 25, 2024, 2:08 PM

#

OK, do you have the ZADIG USB driver installer?

ruby heart Jun 25, 2024, 2:09 PM

#

i think it has to do something with my pc, that there are no permissions to enter the port

ruby heart Jun 25, 2024, 2:09 PM

#

fallow mica OK, do you have the ZADIG USB driver installer?

yes i installed the drivers

flat quarry Jun 25, 2024, 2:09 PM

#

ruby heart yes i installed the drivers

Reboot your pc

ruby heart Jun 25, 2024, 2:09 PM

#

i did

flat quarry Jun 25, 2024, 2:10 PM

#

After installing the dfu driver?

ruby heart Jun 25, 2024, 2:10 PM

#

yes

#

maybe i have to try it with another pc or laptop

fallow mica Jun 25, 2024, 2:13 PM

#

SIlly question, have you tried this with Betaflight versions other than 4.5? I had this happen with someone recently and it wouldn't work with 4.5, but did with older versions - doesn't make sense to me, but that's what happened.

ruby heart Jun 25, 2024, 2:14 PM

#

ill give it a try

#

one sec

#

still not working

fallow mica Jun 25, 2024, 2:16 PM

#

OK, that's what I hoped would happen, so that at least it's consistent.

#

So, if you unplug the Flight controller and plug it back in, does Betaflight connect back in OK?

ruby heart Jun 25, 2024, 2:18 PM

#

yes

fallow mica Jun 25, 2024, 2:19 PM

#

OK, I have seen this a bit and most of the time, re-running the impulse RC driver fixer corrects the issue (sometimes in combination with turning no-reboot on/off). I would also suggest trying another available USB port, if you haven't already.

#

Another thing to try is to press the boot button on the flight controller, then plug it in to USB so that you got straight into DFU inside Betaflight, instead of plugging in, then switching to bootloader for the flash.

#

I don't know if this will help, but it's worth a try.

ruby heart Jun 25, 2024, 2:37 PM

#

Im already doing This

fallow mica Jun 25, 2024, 2:52 PM

#

I guess try another computer if you can?

Maybe you have the Guillemot driver conflict issue

That issue you're speaking of is dfu hijacking, because it enters dfu mode it's not going to be that issue here. It seems to be a conflict after it's in dfu bootloader where flash is blocked
