Updating a device
To update your devices, you'll submit an update to Microsoft. The mobile operator (MO) can help test the updates. When approved, the update goes to the production update server, where customer phones can download and receive the updates through a cellular or a Wi-Fi connection. With the users consent, the device updates automatically, with most of the update processes working in the background.
Before you begin
Prior to submitting updates, complete the following tasks:
Sign up to submit firmware submission and update requests. For more information, see the “Sign up for retail package signing and update submissions” section in Ingestion Client.
Review the update scenarios that apply to you in Update scenarios.
Review the update requirements that apply to you in Update requirements.
Obtain the successfully signed firmware submission ticket IDs for the firmware that devices will be updating from and the firmware that devices will be updating to. For info about how to perform this task, review Submit binaries to be retail signed.

The user data and SD cards cannot be updated. All user data and settings must be preserved when these updates are applied.
These types of updates can only be submitted individually.
