Apple firmware data


DeviceIdentifier API is able to dynamically download and parse Apple firmware images for analytical purposes. It does not store or archive any Apple binaries. It supports iOS, iPadOS, HomePodOS, tvOS and WatchOS devices.

This functionality has no dependancy on any upstream non-Apple API or tools. As such, in the event of outage or error in the or TSSstatus APIs, or the tsschecker tool, this API will continue to function and receive updates normally.

The API’s firmware data can be used in a number of ways, detailed below.

Fetching data on the latest firmware available (and its signing status) for a given Apple device.

Firmware data for a given device is automatically returned with any internal name query. The nested firmware data is in the following format:

    "firmware": [
            "build": "11D257",
            "filesize": 165768907,
            "ota": true,
            "required_build": "11A465",
            "required_version": "7.0",
            "signed": true,
            "signing_started": "2018-11-01",
            "signing_stopped": null,
            "url": "",
            "version": "7.1.2"

Fetching data on a particular firmware release

Information on a given firmware release can be requested with the following format of URI:

    "version": "12.4",
    "release_notes": "iOS 12.4 introduces iPhone migration to directly transfer data from an old iPhone to a new iPhone, includes enhancements to Apple News+ and improves the security of your iPhone or iPad.

            "signed": true, 
            "signing_started": "2019-07-22", 
            "signing_stopped": null, 
            "url": ""

Fetching a full firmware feed

This archive is designed for use with tsschecker, such that it can be patched into tsschecker.c where the API is unavailable.

It provides a JSON index of available over-the-air (OTA) or non-OTA (full) firmwares available for all devices.
