x8 remote control not working after factory reset

Hello all,

I did a factory reset on my x8, but now my remote control is not working like it should. Power button works, home button works. But that's it.
I also have a neo A2 lite remote, and that has the same problem...Air mouse works, home and the power button work...But that's it.
Did I miss something when doing the reset? Do I have to install new firmware to get the remotes working again? I'm stuck :-(

Thanks in advance for the help!

Tom
