Title is what I'm trying to do, but I cant seem to get it to work
I hold the boot button, plug in the usb, wait for orange led to light up and release button.
then open inav and go to flashed, select my target and version
I toggle "No Reboot sequence" (Enable if you powered your FC while the bootloader pins are jumpered or have your FC's BOOT button pressed.)
Toggle full chip erase

and when i load the firmware and click flash i just get this error code
No response from the bootloader, programming: FAILED

PLEASE help 😭

Make sure you're using a data USB cable

#

Can you connect to Betaflight using that cable?

If you can, try the ImpulseRC Driver Fixer if you're on Windows

quick arrow Make sure you're using a data USB cable

If you get no sound from your computer when plugging in the USB cable it's likely it's a power-only cable
