iPhone 11 Firmware: Current IPSW Versions & Downloads

The iPhone 11 line launched in September 2019 across three models: the base iPhone 11, the iPhone 11 Pro, and the iPhone 11 Pro Max. All three use the A13 Bionic chip and all three are still running current iOS. Each model has its own model identifier and its own IPSW — you must match the right file to your exact device before attempting a restore.

Quick answer: all three iPhone 11 models currently run iOS 26.6.1 (build 23G83), the latest signed release. iOS 26.6 (23G71) is also still signed.

iPhone 11 Model Identifiers

The identifiers are not sequential — iPhone 11 is iPhone12,1, Pro is iPhone12,3, Pro Max is iPhone12,5 (iPhone12,8 belongs to the iPhone SE 2020, which shares the A13 chip but is a different product).

Currently Signed iOS Builds

Which Build Should You Install?

How to Restore an iPhone 11 with an IPSW

Back up your device, turn off Find My, connect to a Mac or PC 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 for your exact identifier. All three iPhone 11 models use a Lightning connector.

iPhone 11 and iOS 27

The A13 Bionic has supported every iOS release since iOS 13. Whether A13 devices receive the next major release depends on Apple’s cutoff, announced at WWDC.

iPhone 11 vs iPhone 12

The iPhone 12 (A14 Bionic) succeeded the 11 and added 5G and a new mini form factor. Both generations currently run the same iOS 26.6.1 release. Firmware is never shared between generations.
