What is the final iOS version for the iPhone 5?

iOS 10.3.4, build 14G61, for both iPhone5,1 (GSM) and iPhone5,2 (Global).

What is the final iOS version for the iPhone 5c?

iOS 10.3.3, build 14G60, for both iPhone5,3 (GSM) and iPhone5,4 (Global) - one build behind the iPhone 5, despite launching later.

Can I use the iPhone 5 IPSW on an iPhone 5c, or vice versa?

No. Even though the builds are close, iPhone 5 and 5c IPSW files are tied to their own device identifiers and are not interchangeable.

Can either device be updated past these versions?

No. Both are 32-bit devices, incompatible with iOS 11 and later. These are permanent final builds, not current signing snapshots.

iPhone 5 & 5c Firmware: Final iOS Versions & IPSW

Here is the counterintuitive part: the iPhone 5c, which launched a full year after the iPhone 5, is stuck on an older final build. The iPhone 5 caps out at iOS 10.3.4 (14G61); the iPhone 5c caps out at iOS 10.3.3 (14G60) — one build number behind, permanently. Release order and final-version order are not the same thing here, and assuming otherwise is the easiest way to grab the wrong IPSW.

iPhone 5 & 5c Model Identifiers

Model	Identifier	Final Signed Build
iPhone 5 (GSM)	iPhone5,1	iOS 10.3.4 (14G61)
iPhone 5 (Global)	iPhone5,2	iOS 10.3.4 (14G61)
iPhone 5c (GSM)	iPhone5,3	iOS 10.3.3 (14G60)
iPhone 5c (Global)	iPhone5,4	iOS 10.3.3 (14G60) Why the Newer Phone Has the Older Final Build Apple does not publish a rationale for where it draws each device's signing cutoff, so treat any specific explanation as speculation. What is verifiable is the outcome: the iPhone 5 received one additional signed build (14G61) that the iPhone 5c never got, despite the 5c being the newer device. The lesson for restoring either one is practical, not historical — check your exact identifier's final build rather than assuming both models in this era share one number. What End of Life Means Here Neither device will ever receive a newer signed build. Both are 32-bit hardware, incompatible with iOS 11 and later. Whatever is listed above is the permanent ceiling — not a current snapshot that might change. How to Restore an iPhone 5 or 5c with an IPSW Use iTunes — either an older macOS installation with legacy iTunes, or iTunes on Windows. The modern Apple Devices app does not support hardware this old. Download the IPSW matching your exact identifier: iPhone5,1/5,2 for the 5, iPhone5,3/5,4 for the 5c. Do not assume the two are interchangeable. Put the device into DFU or recovery mode, then Shift-click (Windows) or Option-click (Mac) "Restore" in iTunes and select the downloaded file.
