I looks like I have run into some other problem. When I make all connections to my KK2.1 board (ESCs and Receiver connections) and power on my board, I don't see any text on LCD. It just lits up and nothing else happens and after few seconds a red LED flashes continuously. Sometimes it slows down but then again it doesn't.

When I connect the board using the USBasp programmer to my computer, the board powers up and I can see text on screen.

Please help!

Did you possibly plug the ESCs in the wrong way? That's pretty much what happens.

I figured out what was wrong. I followed this post and now my Quad flies great.

But I still don't know why I am not able to flash it with new firmware.
