Offline system update from a USB flash drive
- Who:
- you, with a Windows PC.
- How:
- you need a Windows PC with internet and a USB port, and a USB flash drive of at least 6 GB formatted as NTFS.

Open the Xbox Startup Troubleshooter (power off, unplug, wait 30 seconds, plug in, hold Pair and Eject and press the Xbox button, release after the second power-up tone), plug in the drive and select Offline system update.

- Xbox's next step is a repair request.
- Evidence to keep:

Formatting the flash drive to NTFS erases all its files. Back them up first.
