just assembled Banggod using tmotor stack f7/45A v2 blheli 32. I get initial tones (DO DO DO but no finished tones(DEE DO) ive tried flashing esc's but still show master protocal deshot, #'s 2 3 4 says protocal unknown. updated board to 4.1.whatever is latest, reflashed esc in blheli32 suite, put a meter across both + & - to each of the motor pads and no continuity. changed the ribbon from fc-esc's,
 
The lack of the final two beeps means the ESCs are not receiving throttle commands from the flight controller.

Check that the signal wires from FC to ESCs are connected
 
Problem solved. Just flashed .7 revision. Good tones. All normal and well. Thanks for the input. Already ordered replacement stack so get to build another one. Lol. I tried this several times. Still do not know what I did different. Changed ramp up to 52 just so I could make sure it was taking write data.
