I am trying to update xbox one console which has not been used/updated in a while by doing an offline update and keep getting following error with OS1 or OS2 or reset to factory defaults files using a USB. All the support options seem to point to repair of the console. Wanted to seek help if possible to see if i am missing anything before going down the repair path. As soon as the offline update process starts at 0%, I am getting this. There are other errors also that I keep getting but thought this might be important one. Any suggestions/help in this regard is much appreciated.
System Error: E101 0000503 80070003
