Hi - Here is a remote.conf file and notes on using a GE Universal Remote Control (model 12404) with a MXQ Pro 4k box. This remote, when programmed with a device code of 0865, will turn the MXQ on and off with the power button. (Remote available at Walmart for $4.97.) Remote.conf file, Key codes and notes are in the zip file.This is a small remote - just a bit bigger than the remote shipped with the MXQ.
Zip file - MXQ_Pro_4k_Remote_wNotes.zip
For anyone who wants Play/FF/Rew/Pause and Stop buttons - this is a good start.
Was able to do this standing on the shoulders of ippon. Thanks for the direction.
