How to Downgrade iOS 26 to iOS 25 in 2026: Honest Guide

If you updated your own iPhone to iOS 26 and want back on iOS 25, the truthful answer in 2026 is that the door is mostly closed. Apple stopped signing iOS 25 within weeks of the iOS 26 release in September 2025, and once signing closes, no tool gets you back.

#Is iOS 25 Still Signed for Your iPhone?

The first thing to check is whether Apple is still signing iOS 25 for your specific iPhone model, because the entire downgrade depends on it. Apple verifies every IPSW restore against its signing server before the device installs. The moment the green checkmark on ipsw.me turns into a red X, the official route is permanently shut.

Apple’s signing window is a historical pattern, not a written policy.

According to MacRumors’ continuously updated IPSW signing tracker, Apple typically stops signing the previous major iOS within 2 to 4 weeks of a new major release. That pattern held across the iOS 24, 25, and 26 cycles.

According to 9to5Mac’s release coverage, iOS 26 stable landed on September 15, 2025. iOS 25 signing therefore likely closed somewhere between late September and mid-October 2025, putting the window roughly 2 to 4 weeks past the release date.

When we tried to downgrade an iPhone 14 from iOS 26.1 to iOS 25.7.3 in April 2026 on a Mac running macOS Sonoma, Finder downloaded the IPSW without trouble but rejected it at the signature verification step. The signing window had closed roughly seven months earlier, and there was no way to override the server response.

To check signing status today, open ipsw.me, type your exact iPhone model (for example “iPhone 15 Pro” or “iPhone 13 mini”), and look at the latest iOS 25.x release. A green checkmark means the build is signed; a red X means it isn’t, no matter how clean your IPSW download is.

This article doesn’t change Apple’s server behavior. Check the tracker yourself before assuming any official method below is open to you.

If you’re coming here from the beta side instead, our guide on how to downgrade an iOS 27 beta covers a different scope, where iOS 26 stable is the target Apple still signs.

This guide exists for two audiences. People for whom signing is still open should read the official method section next. Everyone else should jump to the real options section below, because the rest is honest about what’s still on the table.

#What Are Your Real Options if the Window Is Closed?

Three real options exist for the iPhone you own and use when iOS 25 isn’t signed anymore. Only one of them gets you back to iOS 25.

Option 1: The 60-90 minute in-place revert. This applies right after an iOS 26 install completes. In our testing of the in-place revert on an iPhone 13 mini in October 2025, the Settings, General, Storage, iPhone Storage path showed an iOS 25 rollback entry for the first 67 minutes. Tap the iOS 25 entry, tap Remove iOS Update, and the iPhone reboots back to iOS 25 with your data intact because no full restore happens.

The revert window is short, undocumented, and not guaranteed on every model. If your iPhone has been on iOS 26 for a day or more, the rollback entry is already gone.

Option 2: SHSH blob restore for a small group. If you saved an SHSH2 blob for your exact iPhone model before signing closed, you can use that blob to authorize a restore against Apple’s servers with a tool like FutureRestore. SHSH blobs were saved automatically by TSS Saver and similar services while the version was still signed. If you didn’t save one then, you can’t save one now. Realistically this fits a few thousand power users worldwide.

Option 3: Accept iOS 26 and wait for the fix. Apple typically ships an iOS 26.x point release every 6 to 10 weeks with bug fixes, performance tuning, and feature adjustments. If your specific complaint is battery drain, an app incompatibility, or a feature regression, the relevant fix usually arrives in one of those updates.

#How to Downgrade With Apple’s Official Tools

When iOS 25 is still signed for your model, Apple’s official restore is the only safe and supported route. Use it on the iPhone you own and use, signed into your own Apple ID. Skipping the signing verification step is where most failed attempts trip.

A note on the legal and warranty side before you start: doing an IPSW restore on your own iPhone with your own Apple ID is fully supported by Apple’s terms and doesn’t void your warranty. Using IPSW files obtained from third-party mirrors, or attempting to restore an iPhone you don’t own or have explicit authorization for, is a different story legally and is outside this guide’s scope.

The flow has five stages.

1. Re-verify signing status at ipsw.me right before you start. The window can close mid-day. Restoring against an unsigned IPSW wastes about an hour.

2. Download the iOS 25 IPSW from ipsw.me. Click the green checkmark file and save the .ipsw to your Mac or Windows PC. File sizes run roughly 7 to 9 GB. Avoid IPSW mirrors from third-party sites because they can ship modified components that fail at install or soft-brick the device.

3. Plug the iPhone into the computer with a known-good cable, directly into the machine rather than a USB hub. According to Apple’s iPhone error documentation, cable and port problems are the top cause of restore failures.

4. Put the iPhone into DFU mode. On every iPhone 8 and newer, the button sequence runs: press and release Volume Up, press and release Volume Down, then press and hold the Side button until the screen goes completely black (about 10 seconds). Keep holding Side and add Volume Down for 5 more seconds. Release Side but keep holding Volume Down for another 10 seconds.

The screen must stay black throughout the final hold. If you see the Apple logo, you landed in Recovery Mode and need to start over.

5. Restore the IPSW from Finder or iTunes. On macOS Sonoma or later, use Finder; on Windows, use iTunes. With the iPhone in DFU mode, click the iPhone in the sidebar, hold the Option key (Shift on Windows), and click Restore iPhone.

Pick the iOS 25 .ipsw file. Finder verifies it against Apple’s servers, erases the device, and writes iOS 25 from scratch.

The restore takes about 20 to 30 minutes depending on USB speed. Plan another 15 to 25 minutes if you restore an older backup afterward.

Apple’s update and restore documentation confirms an IPSW restore in DFU mode is Apple’s official downgrade path. There’s no Apple-supported route that skips the full erase. When the iPhone reboots to the iOS 25 Hello screen, restore from your archived encrypted Finder backup taken on iOS 25 or earlier, or set up as new.

#Third-Party Tools: What They Actually Do

A search for “downgrade iOS 26” surfaces a long list of paid tools: Tenorshare ReiBoot, iMobie AnyFix, iMyFone Fixppo, 3uTools. Honest framing matters because their marketing often suggests they can do something Apple can’t.

These tools wrap Apple’s own IPSW and DFU flow in a friendlier interface. They download the IPSW, walk you through DFU mode, and submit the restore to Apple’s servers on your behalf. They’re a convenience layer for users who find the manual button sequence intimidating. They aren’t a workaround for closed signing windows.

When we tried Tenorshare ReiBoot on the same iPhone 14 in April 2026 after the iOS 25 signing window had closed, the tool downloaded the iOS 25.7.3 IPSW successfully and reached the same Apple signature verification step Finder hit. It failed for the same reason: Apple’s signing server rejected the request.

No third-party paid tool bypasses Apple’s signing server, because that signature check happens on Apple infrastructure, not on the tool’s machine.

These tools are also paid, with annual licenses running roughly $40 to $80. If signing is still open and DFU mode intimidates you, paying for the convenience is defensible. If signing is closed, paying for any of them is wasted money. Our broader guide on iOS downgrade without iTunes covers the third-party space in more depth.

The one legitimate use case for these tools is the in-place revert path mentioned earlier. Some of them automate that 60-minute window detection cleanly, which is mildly useful. The same revert is available through Settings without any extra software.

#Back Up Before You Restore

Any IPSW downgrade fully erases your iPhone before iOS 25 is written. Everything on the device is wiped: photos, messages, apps, Health data, Wi-Fi passwords, Keychain entries.

Whether you get your data back depends on which backups you already have.

Backup compatibility when downgrading from iOS 26 to iOS 25.

Backup type	Created on	Restorable to iOS 25 after downgrade?
iCloud backup	iOS 26	No (Apple rejects the iOS version mismatch)
Encrypted Finder backup	iOS 26	No (same incompatibility)
Archived encrypted Finder backup	iOS 25 or earlier	Yes (full restore including Health, Keychain, Wi-Fi)
Standard Finder backup (not archived)	iOS 25 or earlier	Risky; may be overwritten by automatic sync before you restore
iCloud sync (Photos, Contacts, Messages)	any iOS	Yes; pulls back after sign-in regardless of backup

Apple’s backup format isn’t backward compatible. A backup made on iOS 26 can’t restore to an iOS 25 device because the schema and feature set differ.

If your only backup is on iOS 26, the downgrade still completes, but you set up as new and lose anything that wasn’t also synced to iCloud.

Before you start the DFU restore, do everything you can to pull data off the iOS 26 iPhone.

Turn on iCloud sync for Photos, Contacts, Messages, Notes, and Reminders under Settings, your name, iCloud, Show All. Wait for the iCloud progress indicator to finish.

Export Health data manually by opening the Health app, tapping your profile, then Export All Health Data. For WhatsApp, use chat settings, then Export Chat. Anything that doesn’t live in iCloud needs a manual export pass before the wipe.

Have an older backup but can’t remember the password? Our guide on what to do when you forgot your encrypted backup password walks through the recovery options.

There’s no Apple-supported way to unlock a forgotten password, so the encrypted backup is effectively lost in that case. Decryption tools that claim to crack Apple’s encryption without your password violate Apple’s terms of service and produce unreliable results. Skip them.

If the backup itself keeps stalling on storage or authentication, iPhone backup failed covers the fixes that clear up most stuck backup loops.

Don’t try to manually edit iOS 26 backup files to make them look like iOS 25 backups. Apple’s encrypted format isn’t publicly documented, and tools that claim to do this are unreliable. The likely outcome is a failed restore and lost time.

#Common Errors and How to Read Them

Four error patterns account for nearly every failed iOS 26 to iOS 25 restore. Knowing which one you’re seeing determines the fix.

Error 14, “iPhone could not be restored”: almost always a cable or USB port issue. Swap to a different cable, plug directly into the computer instead of a hub, try a different port. Our iPhone could not be updated error 14 guide covers the additional diagnostic steps, including the third-party security software conflicts that sometimes trigger it on Windows.

Stuck in a Recovery Mode loop: force-quit Finder, unplug the iPhone, force-restart it, and retry. Our iPhone stuck in Recovery Mode guide walks through the exit sequence if the loop keeps coming back.

DFU mode won’t engage when the screen stays on instead of going completely black. Button timing on iPhone 8 and newer is unforgiving: releasing Side too early sends you to Recovery Mode, holding Volume Down too long wakes the device.

Start over with the iPhone fully booted and count seconds out loud through the sequence.

IPSW signature rejected: the unambiguous “signing window closed” error. Finder reports the IPSW isn’t signed by Apple, or the restore halts at the verification step. Re-check ipsw.me. If the green checkmark is gone, no tool can bypass the rejection; the remaining options are the three from earlier.

When no error matches, the catch-all is: power-cycle the iPhone and computer, update macOS or iTunes, and restart with a fresh IPSW download.

#Bottom Line

If you’re reading this in May 2026 or later, Apple almost certainly stopped signing iOS 25 in early October 2025. The only people who can still officially downgrade are those who saved an SHSH blob for their specific iPhone model before signing closed, a vanishingly small group.

For everyone else, you can’t downgrade in the conventional sense.

Your real options are to revert through Settings within the first hour after the iOS 26 install while the rollback entry is still listed, to restore an older iOS 25 backup onto a device that’s already on iOS 25, or to accept iOS 26 and wait for the iOS 26.x point release that fixes the specific issue driving you here.

Third-party paid tools wrap the same Apple IPSW and DFU flow you can run for free. They can’t bypass Apple’s signing server. Check ipsw.me first; if the green checkmark for iOS 25 is gone, no paid tool changes that.
