All right. I am and idiot, no kidding. I didn't think about power switch board, and as you said- I found burnt trace in there. After soldering it, everything works Great. Thank you very much for your help, really appreciate it!

Didn't short anything. No burnt traces. Look at the Picture- I decided to solder the two upper left "points" which correspond to +- 5v with 3 and 4 pin. Checked it a little diy and it worked! I'm Just a little curious if it Will not overload anything.

All right So it seems like i dont have power in 3 and 4 pin in the back. Anyone knows what Could go wrong? Could soldering make any damage? Anyone knows the cables which correspond to the front od 9x?

Alright, i think I found the problem. I connected the module to the power (two wires from some Kind of charger) and it bound with receiver while putting power into 3 and 4 pin (counting from top). Has anyone an idea in what order should be the rest of pins?

Did anyone actually manage to bind this module (photo i sent before) with receiver via Er9x?

Try to use ER9x V.822a.The firmware work well in my new 9x.Like MikeB said,using PPM and polarity NEG.

Do you have the same module as i have?

I wanted to add one thing- I don't know if it matters but while flashing new soft, the back part of the 9x was disconnected from the front, so the module was also disconnected. I'll try to contact hobbyking if this afhds 2a works with pcm or ppm. I sent you a photo of this module. Hobbyking says: • ...

Hello. I flashed an er9x to my 9x, and I have afhds 2a module with IA8 receiver on the drone. The problem is that after flashing new soft the module doesn't work. I have changed probably everything in the protocol options and nothing has changed. As far as I've seen, even the red light on the module...
