Can I copy Xbox One updates?

"consoles with firmware of unknown origin, quality or intent were banned permanently from Xbox Live."

I'd suggest getting updates they way most peps get them, using the Xbox 1 Dashboard and your console connected to Xbox Live. If you copy an update file and if it gets corrupted even by 0.0001% from genuine updates Microsoft hands out for the Dashboard on
Xbox 1, it's likely to get banned. If caught Microsoft bans consoles with firmware of unknown origin, QUALITY or intent. And then we get naïve peps coming on here "why we got banned?".

Older peps on here may want to do it though. Accessing the Xbox 360's internal HDD seems to be more simpler than accessing the Xbox 1's internal HDD through the Dashboard. I would like an option to backup in the future my Minecraft worlds on X1 to USB so
probably not know how to do it using the Xbox 1's UI because it is at least a bit different compared to the 360's UI which I'm more familiar with. With Xbox 360's Dashboard it shows you everything pretty much in your consoles HDD.

I'm not sure what you mean by a "severe breach of security". I'll agree external drives aren't opening the door for someone to access other gamers info, CC, etc.

But.....it opens the door for everything else all of which were very common on the 360. Anything from avatar mods, game hacks, achievement hacks,,,the list goes on. Firmware issues are much easier to catch the software mods. Software you need to know where
to look and a general idea of what your looking for.

I don't think so. If it was possible it could potentially open the doors for people who may want to try and manipulate the service in some way.

Well to my knowledge, there has never been a severe breach of security within the Xbox Live service itself, even on the Xbox 360, and that certainly says something about MS. Still, there's no reason to start now.

"Microsoft implements a number of different security measures on its Xbox Live service. One of these takes the form of a proactive security check that assures that only unmodified machines may access their service. On May 17, 2007, Microsoft banned consoles
with modified firmware from Xbox Live. According to Microsoft, consoles with firmware of unknown origin, quality or intent were banned permanently from Xbox Live. A Microsoft representative indicated that the action was taken to assure "the integrity of the
service and protect our partners and users."

It's more straight forward to download it rather than go through all that hassle. Heard that if you sign into a modded console you account gets banned. This is also why it's best to only buy consoles new from authorized Xbox retailers which are in all countries
Xbox Live is in (US/UK/NZ/AUS).
