Could you please tell us when you bought the unit and your order number?
This information is very important for us to provide you the accurate and best solution.
Regarding your issue, please check if the red and yellow wire is reverse to your original connector wire pins.
And you can refer the another forum to check the way to check.

In case the problem is still unsolved, I will ask the factory to provide the original firmware for your unit.
