Hi Intel
First up tanker9x is no longer supported. You should update to the latest version of er9x if you have a plain 9X and ersky9x if you have the 9XR Pro
All the latest firmware updates are here:
www.er9x.comhttp://www.er9x.com/er9x.hexor
http://www.er9x.com/ersky9xr_rom.binAlso on that page you will find the er9x manual

Cheers
