Sp Racing F3 -OSD (DELUX)

Help Needed.

Today finally decided to mount my SP Racing F3.

Issues - when tying to flash the firmware - keep getting the error - NO response from boot loader.
Tried with both cleanflight and betaflight, no success.

What am i doing wrong?
How can i fix this?
Pictures and video attached

Shirt the boot pads with something before you powe up - I would use a pair of metal tweezers, hold one leg on each pad and plug it in, once it has booted you can remove the tweezers

Thanks Cheredanine, was able to update and connect to Cleanflight, race flight and betaflight, but while soldering i destroyed the board, now have received the Kakaute f4 AIO and am scared to solder it
