Downloading and installing an IPSW comes down to three things done in order: identify your exact device, get the matching file from a page built for that device, and confirm it's still signed before you restore. This guide walks through all three and routes you to the actual download index rather than trying to be one.
Direct answer: find your device's model identifier, open its specific device page to download the matching IPSW, confirm the build is still signed, then restore through Finder, the Apple Devices app, or iTunes.
What an IPSW Is, Briefly
An IPSW is Apple's firmware package for a specific device — not a generic "iOS file." Every model has its own IPSW, tied to its internal identifier. For the full explanation of what's inside the file and how it's used, see what an IPSW file is.
Step 1: Identify Your Exact Device
Open Settings → General → About → Model Number and tap it to reveal the model identifier (for example, iPhone14,5). The marketing name alone isn't enough — several models share a name across regions or storage variants but use different identifiers. For the full method, including what to do if the device won't boot, see how to identify your exact iPhone model.
Step 2: Get the File From Your Device's Page
Once you have your identifier, the download itself doesn't happen on this page — it happens on the page built for your exact device, which lists every signed and historical IPSW for that identifier. Browse by product line:
Each product page links to every device within it, and each device page lists its available IPSW files directly. This is the actual archive — a single article can't keep pace with every model and every build, so it isn't trying to.
Step 3: Confirm the Build Is Still Signed
Apple only allows a restore to a build it's currently signing — typically the latest release, sometimes one version back. A file that worked for someone else last week can fail today if Apple has since stopped signing it. Before you download, check the live signing status for your exact identifier and build.
Installing the IPSW
Back up your device first — a restore erases it. Turn off Find My (Settings → your name → Find My → Find My iPhone/iPad). Connect to a Mac or PC. In Finder (modern macOS), the Apple Devices app (Windows), or iTunes (older Mac/PC setups), select your device, hold Option (Mac) or Shift (Windows), and click Restore. Select the IPSW file you downloaded from your device's page. If the device is unresponsive or won't connect normally, put it into Recovery Mode first.
If the Install Fails
Most installation failures fall into two categories: signing problems and connection problems. If you see "This device isn't eligible for the requested build" or Error 3194, that's almost always a signing or device-match issue — see the Error 3194 fix guide. If you see Error 4013 or 4014, that's usually the cable, USB port, or computer rather than the file itself — see the Error 4013/4014 fix guide.
Frequently Asked Questions
Where do I actually download the IPSW file?
From the device page for your exact model, not from a general download page. Start at the iPhone or iPad product page, find your model, and download from there.
Can I use any IPSW file, or does it have to match my exact device?
It has to match your exact model identifier. Two devices with the same marketing name can use different identifiers and different IPSW files.
Why does my download say the version is no longer available?
Apple stops signing older builds over time. Check current signing status for your device before assuming a version is still installable.
Does installing an IPSW erase my device?
A Restore erases the device. An Update through the same tools can preserve data if the device is already functioning normally.
What's the difference between Finder, Apple Devices, and iTunes for this?
They do the same job on different platforms: Finder on modern macOS, the Apple Devices app on Windows, and iTunes on older Mac versions or PCs without the Apple Devices app.
