I purchased 4 RCTimer 30A flashed ESCs and I was able to calibrate the throttle on three of the four ESCs, but couldn't get the fourth to work, so I figured I needed to flash the fourth one. I purchased a USBasp programmer off of ebay and tried flashing with the ESC Flash Tool and with the KKMulticopter flash tool.

When using the ESC Flash Tool I got the following error:

"Unable to connect to remote server"

I am soldering directly to the esc. A few photos are attached. Any thoughts on what is going hay wire? Thx.

When I used the KKMulticopter flash tool, I got the following error:
