Hello.

Please fully charge phone's battery with external charger (at least to 4.1V). Connect the device directly to motherboard USB port, don't use any USB hubs or PCI USB extention cards - this is important, and repeat the Repair procedure again. Try to perform the operation on another PC. Try several times.

Also, this can be HW problem:
