Hi does anyone know what that symbol means? I assume it means some kind of warning as its...

Hi Steezzy. My name is Kyle and I'm an independent advisor.

The symbol means that the disc for this game isn't inserted in your console. If you insert the game disc the symbol will disappear and the game will be playable.

Thanks,

Hi Jemmas

Thats an interesting error code. Here are some of the solutions for similar error codes, but not that exact one.

If you do however need to do an offline install, then here's the link to assist with that. It covers all the bases to do an offline install over USB, just remember your USB has to be bigger than 6GB and be formatted to NTFS, i'd also recommend it being a 3.0
USB if possible.

You could try to fix it by selecting the factory reset. If this won't fix it it is an hardware error. In that case you have to send it to Microsoft for a repair.

What won't take your USB? PC or Xbox? Are you following all the steps in this page https://support.xbox.com/en-US/xbox-one/console/reset-factory-defaults-using-usb-flash-drive?

The xbox is not taking the USB it installs and verifies the install but turns off on the applying install bit and now its showing no display on my screen but xbox has the light on
