I have the A8V3 and I can't get this to flash via USB.

I followed those instructions but when I hit start, the board cycles the relays a number of times then returns "2-sync fail Tips: Please refer to the chip datasheet and confirm that the strapping pins's status is correct"
I've tried the baud 921600 as well as 115200 and 1152000, same results.
