Hi,Can anyone help me? My FC cannot be used after hijacking DFU. After reading several forums and trying the steps given, I finally managed to enter recovery mode Bootloader but it becomes a problem when the firmware flash is not successful. I have included some pictures for reference. When the USB cable is connected to the FC there is no sign of connection except when Press the boot button and can connect DFU STM32 bootloader but failed to flash firmware.The FC only lights up red when the USB cable is connected.I'm stuck, hope someone can help.TQ

Yes,I used zadig and impulseRC and it didn't work either. I even tried STM32cubeprogrammer but it didn't work.

alpine dust Do you choose board and version fimwere?

Yes...before this there was no problem but after the DFU hijacking happened, it kept happening like this. I'm not even sure how the DFU hijacking could happen.

I think :
-Either the target is incorrect
Or dfu was not correct

Is anything connected to the FC?

#

I'm not sure but when the usb is connected, only the red light comes on without blinking.

You might need to remove power or connections from any device on a uart. I've got one drone where I have to unplug the Vista to get it to flash, I have another one I have to unplug the GPS.

Initially I followed this method and was able to enter the DFU bootloader but was unable to flash the firmware.
