No signal from CC3D to ESC's

Hi,

I am struggling to get my ZMR 250 quad off the bench. Its a new kit (never flown).

My problem is basically, when I plug in the flight battery, I get 3 different tones, followed by ~5 seconds of silence, then a single beep about every 3 seconds. Putting my ear to the motors, sounds like all of them are beeping in sync.

Rx/Tx attached, it doesnt matter, even in Librepilot once I reach the point in wizard of hooking up the battery, same problem.

Not a clue what brand the ESC's are but attached a pic.

I did check wire resistance (looks good), and termination locations against the LibrePilot diagram (also looks good)....Im stumped. Note: I did originally have signal wires hooked to wrong points. motors worked then, just wrong ones. Once rewired to correct points (1-4), no luck. I cant think of anything else I changed to cause a problem. Could the original error mess things up?

Please help. Im big into RC but mainly nitro.....new to Quads.
