Was trying to flash the SB2209 but sadly i wasnt able to put it into DFU Mode at all. Tried the BOOT+RESET method and then even uninstalled it from my Stealthburner and directly connected it to the M8P via USB (Jumper for 5V is also installed).

What else could be causing this?

Swapped usb cables? Nothings plugged into the pcb?
