The Tracker ID key sequence (Home x5 Back x5) does not work on my Roku 3 4200X
Serial Number is 1GU44G110762
Device Model is Roku-3
Device ID 4200X
Software Version is unknown as it has been factory reset and needs to download new software. The download is not working (Error 003), this is the actual problem.
Seems that the post above from @RokuEmmanuel-D has been edited since I started looking for the requested info. It's all now in one place, hope this helps.
