Pixhawk PX4 with x4rsb/XSR and QX7

So I have tried for a WEEK now to get my new Pixhawk to work with my new X4RSB and my QX7. The Pixhawk is setting up fine via USB but I am stuck on the binding. I have tried every combination of firmware (frk) files from the Frsky website with no luck. I was thinking maybe my X4RSB is bad so I bought an XSR but its acting the same:Plug XSR into FC for +5V (no other peripherals connected to FC) with FS button pressedRed and green LEDs both on steadyTurn on QX7, hit bind (D16, channels 1-16)NOTHING HAPPENSTried the same but opposite: bind FIRST then apply power to Rx. No dice.I have been trying all FCC/Non-EU firmware since I am in the US. Ordered both Rx from Amazon and Tx from a US website (I think). I did try LBT and EU pairings but same story.I go to frsky.com, find the XSR (or X4R if that's the one I'm using) page and downloaded the latest 170619 FRK file. I used it to flash "internal module" on the QX7 and also used it to flash "external device" to the Rx via the 3-pin port on the bottom.Does the same file flash both internal module and Rx? I also tried navigating to XJT on the Frsky website to flash internal. QX7 doesn't recognize that the latest version (170317) is even on the SD card.What the heck am I doing wrong? What i wrong with my thinking or files I am downloading? What else can I try? I'm pulling my hair out!Thanks in advance!Pic attached of my setup...
