Binding problem

Dear,

I can't bind my devo 10 tx with deviation 4.0.1 to my walkera qr x350 pro. I use protocol devo but nothing happens. Should i start first the binding proces and then connect the battery off the quad ? Btw i also tried with deviation 3.00 same problem.

I also reversed the firmware to stock walkere firmware but there everything in the menu shows up as "YYYYYYYYYYY". The english language is selected tho.

greetings Alex

Yep.
Touch the Fixed ID numbers, delete the ID numbers in the next page.. it will then say "NONE" you'll have to hit the "bind" tab when you plug in the quad, Deviation will take a few seconds counting down then try to bind to your quad.
You can then set a fixed ID for the quad by touching the numbers again, entering your ID that you want, and the Tx will enter the ID as a fixed ID for the quad model. If you had a fixed ID in the Rx of the quad, you need to clear it or Deviation wont bind to it. Then reset it, I believe.
