XBOX one S E100 Error

So I bought this XBox one S as a no display fault.
On opening it I found it had had a previous repair attempt and I needed to replace both the hdmi and the retimer - which I did.
I tested it (without the wifi card) and it booted fine - went into 1080 and even allowed me to start a game on the drive.
When I rebuilt it with the wireless card in and booted it - it said I needed an update - which i tried to do - it downloaded fine but then got to 59% and stopped with an E100 000007003 8091008 error

I have tried swapping out the hard drive (not the bluray) and get the same error.
This is showing on most sites as a bluray drive error - is there any way of turning it into an all digital edition?

Any other ideas would be welcomed
