I just purchase a Traxxas TQI 2 channel with a docking base and receiver off ebay in working ordered. The transmitter turned on and lite green, receiver bind just fine and worked and the transmitter connected with my Iphone4. Now, my problem occurred when I was going through some features while the transmitter was on but not the receiver while switching between a Iphone4 and 3s. I went to update firmware while I was on my Iphone4 and it said that it was up to date. B/c my Iphone 4 is my personal phone I wanted to use the 3s. So I went into check firmware update on the 3s and it was stuck in loading. So I backed out of it but the transmitter was still connected to the Iphone. I went into the training mode just to see if everything was working and it did the same thing, just sat it loading mode. I turned off the transmitter and disconnected the Iphone. When I went to do a reset on the transmitter both green and red LED lights went lite at the same time. I'm getting no response from anything, I cannot reset the transmitter. I hold the menu and set button when the transmitter is off then turn it on and the same green and red lights are on and the green light that flashes once then goes back to green and red lite at the same time. If I press the set button the lights turn off. The transmitter won't even connect to the both Iphones now. I have no idea what happen.
