[Under investigation] Can't Update Software - Error 004

When it try’s to update and I get the error code 004, I hit ‘OK’ my Roku device stops working.  No icons on the screen just the blank background.  This is lasting longer and longer every time.  I’ve tried the  reset and update menu and nothing works.   I have to an unplug the Roku device for a few minutes and then power it up to be able to use it. 
This is extremely frustrating
