Maybe the battery drains faster, a favorite app keeps crashing, or the new interface just doesn’t work for you. You want to downgrade ios software, and that’s exactly what we’re going to walk through. But here’s the catch: Apple makes this deliberately difficult. As of 2026, Apple typically stops signing older iOS versions within 7 to 14 days after releasing a new one. That means if you missed that window, you can’t simply hit a button in Settings and roll back. The process depends entirely on your specific situation. So what does it actually take to go back? Let’s start with the biggest obstacle you’ll face. ## So You Want to Downgrade iOS — Here’s What You’re Up Against Downgrading iOS isn’t like installing a Windows update where you can roll back with a single click. Apple treats the operating system like a security vault. Once you step forward, the door locks behind you. The biggest hurdle is the signing window. Every time Apple releases a new iOS version, they digitally “sign” it. That signature is what allows your iPhone to accept and install the firmware. Once they stop signing an older version, the phone refuses to install it. No exceptions, no back door. Your device generation also matters. If you have an iPhone with an A12 chip or newer (iPhone XS, XR, and everything after), downgrading is much harder. You need saved SHSH blobs and a jailbreak just to set the nonce. If you’re on an older device (iPhone X or earlier), the process is simpler but still requires blobs. The other big risk is the Secure Enclave Processor (SEP). That’s the chip that handles Face ID, Touch ID, and Apple Pay. If you downgrade to a version whose SEP firmware isn’t compatible, those features stop working. Sometimes the phone won’t even boot. In our research, the most common reason people want to downgrade is a bad update. Either a beta version they installed for testing, or a public release that ruined their battery life. The second most common reason is losing a jailbreak. ## The Single Most Important Thing: Apple’s Signing Window The signing window is the entire foundation of iOS downgrading. Think of it as Apple’s digital permission slip. When you restore your iPhone, Apple’s servers check the version you’re trying to install. If it’s still signed, the server says “yes” and the restore proceeds. If it’s unsigned, the server says “no” and the restore fails. Apple’s signing window for a given iOS version usually stays open for about 7 to 14 days after a newer version is released. Sometimes it’s shorter. Sometimes they close it in under 48 hours. There’s no fixed schedule. You can check the current signing status using a site like [the iPhone Wiki](https://www.theiphonewiki.com) which tracks which versions are still signed for each device model. Here’s what that means for you: - If the version you want is still signed, you can downgrade using a standard iTunes or Finder restore. No blobs needed. - If the version is unsigned, you need saved SHSH blobs to bypass the signing check. - If you never saved blobs and the version is unsigned, you’re stuck. There is no way to downgrade without them. That’s the hard truth. Most people discover this after the window has already closed. They search for a downgrade method, find guides, and then realize they missed the only easy opportunity. The signing window applies to every iPhone, iPad, and iPod touch. It doesn’t matter if you’re on a carrier-locked device or an unlocked one. The restriction is server-side, not device-side. ## Do You Have Saved SHSH Blobs? (The Big Decision) Now we reach the decision point. Your entire downgrade path depends on whether you saved SHSH blobs while the version you want was still being signed. SHSH blobs are a cryptographic signature unique to your device. When you save them, you’re basically storing the permission slip Apple issued. FutureRestore, a third-party tool, can then use those blobs to trick Apple’s servers into letting you install an unsigned version. The process splits into two branches. ### If You Have Blobs: Your Next Steps Depend on Your Device If you saved blobs, great. You have a path. But the steps depend on your chip generation. | Device Generation | Blob Method | Nonce Setting Required? | SEP Compatibility Check Needed? | | --- | --- | --- | --- | | iPhone X and earlier (A11 and below) | Saved blobs, no jailbreak needed | No | Yes | | iPhone XS and later (A12 and above) | Saved blobs, jailbreak required | Yes | Yes | If you have an older device, you can use FutureRestore without a jailbreak. You just point it at your blob file and the IPSW firmware. If you have a newer device, you must jailbreak first to set the nonce generator. The nonce is a random number that FutureRestore uses to match the blob to your phone. Without a jailbreak, you can’t set it. You also need to check SEP compatibility. If the SEP firmware on the version you’re downgrading to is incompatible with the version your phone expects, Face ID, Touch ID, and Apple Pay will break. In some cases, the phone won’t boot at all. ### If You Don’t Have Blobs: Your Options Are Limited If you never saved blobs, your options are narrow. You cannot downgrade to an unsigned version. Period. There is no workaround, no hidden menu, no third-party tool that bypasses this. Your only option is to check if the version you want is still signed. If it is, you can downgrade using the official method. If it’s not, you’re stuck on your current version. Some people try to use third-party tools like 3uTools that claim to force downgrades. In our research, these tools often fail or cause data loss. They don’t bypass the signing check. They just try to exploit loopholes that Apple frequently patches. The only real alternative is to wait for a future jailbreak that might allow you to set a custom nonce. But that’s unpredictable. It could take months or years. And for newer devices, jailbreaks are rare. ## How to Downgrade (Step-by-Step for Your Situation) Let’s lay out the two methods. Choose the one that matches your situation. ### Method 1: The Official iTunes/Finder Restore (Only Works for Signed Versions) This method works if the version you want to downgrade to is still being signed by Apple. No blobs, no jailbreak, no third-party tools. Steps: 1. Download the correct IPSW file for your device model from Apple’s official servers. 2. Connect your iPhone to your computer and open iTunes (Windows) or Finder (macOS Catalina or later). 3. Put your device into Recovery Mode (quick press Volume Up, quick press Volume Down, hold the Side button until the recovery screen appears). 4. Hold the Option key (Mac) or Shift key (Windows) and click the “Restore iPhone” button. 5. Select the IPSW file you downloaded. 6. Confirm the restore. The process will wipe your device and install the older iOS version. 7. Restore from a backup you made before the update. This method is simple and safe. But it only works if Apple is still signing that version. Check the signing status before you waste time downloading the IPSW. ### Method 2: FutureRestore with SHSH Blobs (For Unsigned Versions) This method is for advanced users who saved blobs. It uses the FutureRestore command-line tool. Steps: 1. Download the correct IPSW for the version you want to downgrade to. 2. Download FutureRestore for your operating system. 3. If you have an A12+ device, jailbreak your phone and set the nonce generator to match the one in your blob file. 4. Open a terminal or command prompt and run the FutureRestore command with the IPSW and blob file paths. 5. Wait for the process to complete. It can take 15 to 30 minutes. 6. Once done, set up your device and restore from a backup. Warning: This method is riskier. If you get the blob file wrong, the wrong IPSW, or the wrong nonce, you can brick your device. Only attempt this if you’re comfortable with the command line. ## What Could Go Wrong? Common Mistakes That Brick Your Phone Let’s talk about the most common errors people make. These are the mistakes that turn a downgrade attempt into a paperweight. - **Using the wrong IPSW.** Every iPhone model has a specific firmware file. An iPhone 14 Pro IPSW will not work on an iPhone 14. Double-check the model number. - **Ignoring SEP compatibility.** If you downgrade to a version whose SEP firmware is too old, Face ID, Touch ID, and Apple Pay stop working. In some cases, the phone will boot loop or refuse to activate. - **Interrupting the restore process.** If the USB cable disconnects or the computer crashes during a restore, the phone can enter a permanent recovery loop. You might need to reinstall the same version. - **Forgetting to set the nonce (A12+ devices).** If you have a newer device and you skip the nonce setting step, FutureRestore will fail. The blob won’t match and the restore will error out. - **Using a corrupted blob file.** Blobs can get corrupted if they were saved incorrectly or if the file was modified. Always save blobs from a reliable source like TSS Saver and verify the file. - **Not backing up data first.** Downgrading wipes your device completely. If you don’t have a backup, you lose everything. And you can’t restore a backup from a newer iOS version to an older one. That means you also lose recent data. In our research, the most common cause of a bricked phone is someone trying to downgrade without checking SEP compatibility. They assume any older version will work, and it doesn’t. Always check the SEP compatibility chart for your device before you start. ## Final Decision Guide: Can You Do It? Let’s boil this down to a simple yes or no based on your specific situation. Answer these questions in order. **Is the version you want still being signed by Apple?** Check a signing status tracker. If yes, you can downgrade today using the official iTunes or Finder method. No blobs, no jailbreak, no risk. If no, move to the next question. **Did you save SHSH blobs for that version?** If yes, you have a path. You need FutureRestore and a compatible SEP. If you have an A12+ device, you also need a jailbreak. If no, you cannot downgrade to that version. Full stop. **Are you willing to jailbreak?** For A12+ devices, jailbreaking is required to set the nonce. If you’re not comfortable with that, your downgrade path is blocked. For older devices, you don’t need a jailbreak at all. **Is the SEP compatible?** Check a SEP compatibility chart for your device and target version. If the SEP doesn’t match, you’ll lose Face ID, Touch ID, and Apple Pay. In some cases the phone won’t boot. Don’t skip this check. Here’s a quick reference table for your decision. | Your Situation | Can You Downgrade? | Method | Risk Level | | --- | --- | --- | --- | | Version still signed | Yes | iTunes/Finder restore | Low | | Version unsigned, have blobs, A11 or earlier | Yes | FutureRestore, no jailbreak needed | Medium | | Version unsigned, have blobs, A12+ and jailbroken | Yes | FutureRestore with nonce set | High | | Version unsigned, no blobs | No | None | N/A | | Version unsigned, have blobs, no jailbreak (A12+) | No | Need jailbreak first | N/A | If you’re in the “no” category, don’t waste time on sketchy third-party tools that promise miracles. They don’t work. Your best bet is to save blobs for the current version while it’s still signed, then wait for a future jailbreak or a signed version you actually want. ## Frequently Asked Questions ### Can I downgrade without losing my data? No. Downgrading requires a full wipe of your device. You can restore from a backup after the downgrade, but only if that backup was made on the same or older iOS version. Backups from a newer version cannot be restored to an older one. ### How long does Apple sign iOS versions after a new release? Typically 7 to 14 days. Sometimes shorter. There is no official schedule. Apple can close the signing window at any time without notice. Check a signing status tracker daily if you’re waiting for a specific version. ### What happens if I interrupt the downgrade process? Your phone can enter a permanent recovery loop or fail to boot. You might need to restore to the current signed version using iTunes or Finder. If the bootloader is corrupted, you may need a computer with advanced recovery tools. ### Will downgrading break Face ID or Touch ID? It can, if the Secure Enclave Processor firmware on the target version is incompatible with your device. Always check SEP compatibility before downgrading. If the SEP doesn’t match, those features stop working. Sometimes the phone won’t activate at all. ### Can I downgrade from a beta to a public release? Yes, but only if the public release is still being signed. Apple usually signs the current public release for a short time after a beta goes out. Check the signing status before you try. If it’s unsigned, you need saved blobs just like any other downgrade. ### Do I need a computer to downgrade? Yes. Both the official method and FutureRestore require a computer. You cannot downgrade directly from your iPhone’s Settings app. The only option from Settings is to update to a newer version, not roll back.
