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:

avrdude.exe done. Thank you.

Error during writing flash.
Please try again with a current limiting power supply attached to the battery wires of the ESC. You then have to remove the 5V connection from the USBasp.

There should be no difference in calling avrdude on 8 and 8A ATmega.
