Buddy Board not flashing on prusa mini...

Hi all, I had a mini on a shelve, so tried to flash it, but...
I just can't get anywhere. I've broken the tab, shorted the pins, screen in flash mode.... 12 mhz....
I've got everything ready but still get this : dfu-util: Warning: Invalid DFU suffix signature
Any hope would be apreciated

Failed to flash to 0483:df11: Error running dfu-util

If the device is already in bootloader mode it can be flashed with the
following command:
make flash FLASH_DEVICE=0483:df11
OR
make flash FLASH_DEVICE=1209:beba

If attempting to flash via 3.3V serial, then use:
make serialflash FLASH_DEVICE=0483:df11

make: *** [src/stm32/Makefile flash] Error 255
