Flashing Octopus Board V1.1 & RatOS

I am struggling to flash an octopus board for my V-Core V3. I tried flashing it with a microSD card because the dfu was not detecting the octopus board. I tried removing all the jumpers and just connecting the board to flash it and many more but it doesn't seem to work. I use RatOS v.2 and I'll attach the screenshots from there. Also I was worried that the cable was not a data cable so I used the same cable for the working V-Core we have in the Lab. It didn't change anything either.
