iPhone 11 Pro Firmware: IPSW Downloads by Model

The iPhone 11 Pro and iPhone 11 Pro Max share a chip, a release date, and an iOS version — but not a firmware file. Each has its own model identifier, and downloading the wrong one fails at verification before the restore even starts. This guide covers what's specific to the two Pro variants: their identifiers, what actually differs from the standard iPhone 11, and how to avoid mixing them up.

For the full three-model iPhone 11 lineup (including the standard model), see the iPhone 11 Firmware guide. This page goes deeper on the two Pro models specifically.

iPhone 11 Pro and Pro Max Identifiers

Model	Identifier	Chip	Screen
iPhone 11 Pro	iPhone12,3	A13 Bionic	5.8"
iPhone 11 Pro Max	iPhone12,5	A13 Bionic	6.5"

The two identifiers are easy to transpose — iPhone12,3 and iPhone12,5 aren't adjacent, but both get confused with the standard iPhone 11's iPhone12,1. Attempting to restore one model's IPSW to another fails at Apple's signing verification before any files are written — a failed attempt and a wasted download, not a partial install.

What Actually Differs Between Pro, Pro Max, and Standard

All three iPhone 11 variants run the same iOS version and build number at the same time. The Pro and Pro Max share the same triple-camera system and telephoto lens that the standard iPhone 11 lacks, and firmware for that camera hardware is what actually distinguishes the Pro package from the standard one, not iOS version eligibility. Between Pro and Pro Max specifically, the difference is screen size and battery capacity only; both use identical internal hardware otherwise, which is why the identifier separation exists but the iOS build does not.

Restoring an iPhone 11 Pro or Pro Max

The restore process is identical to any other iPhone 11 model — there is no Pro-specific restore procedure. Back up your device, turn off Find My (Settings → your name → Find My → Find My iPhone), connect with a Lightning cable, and in Finder, the Apple Devices app, or iTunes hold Option (Mac) or Shift (Windows) and click Restore, then select the IPSW matching your exact identifier — iPhone12,3 for Pro, iPhone12,5 for Pro Max. If the device is unresponsive, use Recovery Mode first.

Before downloading, confirm the build is still signed: Apple signs only the current build at any given time — check the live signing status rather than assuming a version you've seen mentioned elsewhere is still installable.

iPhone 11 Pro Firmware FAQ

Is the iPhone 11 Pro Max firmware different from the iPhone 11 Pro?

Yes. They share the A13 Bionic and run identical iOS versions, but each has its own model identifier (iPhone12,3 for Pro, iPhone12,5 for Pro Max) and its own IPSW file. The files are not interchangeable.

What is the model identifier for the iPhone 11 Pro?

iPhone12,3. The Pro Max is iPhone12,5, and the standard iPhone 11 is iPhone12,1 — all three are easy to mix up since none of the numbers are sequential.

Does the iPhone 11 Pro Max get a different iOS version than the Pro?

No. Both run the same iOS version and build number at the same time. The difference between them is hardware (screen size, battery), not software eligibility.

Can I use an iPhone 11 Pro IPSW on a Pro Max, since they're so similar?

No. Despite sharing a chip and camera system, the two have distinct identifiers and the restore will fail at the signature check before anything is written to the device.

What's different about restoring a Pro or Pro Max versus a standard iPhone 11?

Nothing in the restore procedure itself — the steps in Finder, Apple Devices, or iTunes are identical across all three iPhone 11 models. The only thing that changes is which IPSW file matches your exact identifier.
