Hi there, 20cm wires is a bit long in my opinion - should be 10cm, but still - if your board is "hungry" - there may be a voltage drop and the resulting voltage level is insufficient for the successful flashing. As for "desoldered & flashed & soldered and nothing happens" - if you're confident your hardware is OK, then there may be an issue with a proprietary BIOS image that you are flashing, and I could only suggest searching for a good BIOS online or trying to extract it from a manufacturer's UEFI update utility if nothing helps.
