My phantom blinks 4 yellow lights fast. I can't stop it, the compass isn't loose. When I connect it to the software I get no signal from my controller but just "CFG-ERR: Configuration error, this may cause by firmware upgrade from old version.or abnormal Tx calibration. Re-calibrate your transmitter,and power cycle your controller and check all of the parameters." I don't know how to calibrate my transmitter and I can't seem to find a video showing how to do so. Please help me!!
