Hi I have a RTF 450 heli, I made a error with the t6 config, and now It will not throttle up. Please advise?

It is a 6ch remote and at first when I tried it, I was able to let the main blades spin, but I must have done something wrong in the t6 config program, because it will not spin the blades now. Please I need help with this, I have been trying to figure this out, but no luck. thanks
