How To Fix Error Unable To Request Shsh On 3utools When New May 2026

The "Unable to request SHSH" error in 3uTools typically occurs when the software cannot verify the digital signature (SHSH blob) required by Apple's servers to flash or restore a specific iOS version. Common Fixes

Update 3uTools: This is the most common solution for newer devices like the iPhone 15 Pro. Open 3uTools, click the Menu button in the top right, and select Check for Update.

Verify Signed iOS Versions: Apple only allows the installation of iOS versions it currently "signs". You can check which versions are available for your specific device at ipsw.me. If the version you are trying to flash is no longer signed, the request will fail.

Check Network Stability: An unstable internet connection or a firewall blocking 3uTools from communicating with Apple's servers can trigger this error. Ensure you have a stable connection and try disabling any VPNs.

Use External SHSH Host: For advanced users, you can manually obtain the SHSH blob by copying your device's ECID or EID from 3uTools and pasting it into the shsh.host website to generate an AP ticket. Advanced Troubleshooting

Try iTunes Restore: If 3uTools consistently fails at the 9% mark with this error, try using the official iTunes (or Finder on Mac) to restore the device. This sometimes bypasses handshake issues between 3uTools and Apple's servers.

Check Hardware (NAND): If the error persists specifically at 19% or 20% in Easy Flash mode, it may indicate a physical hardware issue with the device's NAND (memory/storage) chip, which may require professional repair.

2. Check signing status

  • Go to IPSW.me → Select your device → Check which iOS versions are signed.
  • If your target iOS is not signed, you cannot save SHSH for it (even with 3uTools).

3. Fix Attempts (For Signed Versions)

Conclusion: Don’t Panic; Use the Right Method

The error “Unable to request SHSH on 3uTools when new” is annoying but rarely a sign of a broken device or permanent failure. In most cases, it happens because:

  • Apple stopped signing the version,
  • 3uTools is outdated,
  • Or you need to switch to the on-device request method.

By following the fixes in this guide—updating the software, checking signing status, changing request sources, or using alternative tools like TSS Saver—you can successfully save SHSH blobs for any still-signed iOS version.

Remember: SHSH blobs are your ticket to downgrading or restoring custom firmwares in the future. Investing a few minutes to understand and fix this error will pay off the next time Apple forces an update you don’t want.

Final tip: If all else fails, wait 24–48 hours. Sometimes, Apple’s TSS servers experience high load right after a release, and 3uTools errors resolve automatically once the initial rush subsides.

Title: A Comprehensive Guide to Fixing the "Unable to Request SHSH" Error on 3uTools The "Unable to request SHSH" error in 3uTools

Rating: ★★★★☆ (4/5)

If you are an iOS user who likes to tinker with their device—whether for downgrading, jailbreaking, or saving blobs—you are likely familiar with 3uTools. It is one of the most versatile all-in-one tools for iOS device management. However, if you have recently tried to save your SHSH2 blobs, you may have encountered the frustrating error message: "Unable to request SHSH."

This usually happens when Apple stops signing a firmware version, but if you are seeing this error when a version is new and still signed, it can be incredibly confusing. Here is a review of why this error occurs and a step-by-step guide on how to fix it.


Fix #5: Disable Antivirus and Firewall Temporarily

This sounds basic, but 3uTools uses non-standard ports and HTTP requests that some security software blocks, especially after a new iOS release (when signature databases get updated, and antivirus may misidentify 3uTools as a threat).

Steps:

  1. Temporarily disable Windows Defender, McAfee, Norton, or any third-party firewall.
  2. Disable VPN or proxy if active.
  3. Run 3uTools as Administrator (right-click → Run as Administrator).
  4. Try saving SHSH again.

If it works, add 3uTools to your antivirus exception list and re-enable protection. Go to IPSW


How to Fix "Unable to Request SHSH" on 3uTools When Using a New iOS Device or New iOS Version

If you are an iPhone or iPad user who enjoys jailbreaking, downgrading, or simply preserving your device’s signing window, you have likely used 3uTools. It is one of the most comprehensive third-party tools for iOS management. However, a frustrating roadblock often appears when dealing with a new device (e.g., you just unboxed an iPhone 15) or a new iOS version (e.g., iOS 17/18): the dreaded error message: "Unable to Request SHSH."

This error typically appears when you attempt to fetch SHSH blobs via 3uTools’ "Save SHSH" feature. For beginners, SHSH blobs are digital signatures Apple uses to verify iOS restores. Saving them is the only way to downgrade your iPhone later. When 3uTools cannot request them, panic sets in.

Do not worry. In this guide, we will dissect exactly why this error occurs when dealing with new hardware or software, and provide 10 proven methods to fix it permanently.


2. Check Your Computer's Configuration

Ensure your computer's date and time are correct. Apple verifies SHSH blobs based on the current date and time.

  • Correct Date and Time: Make sure your computer's clock is set to the correct date and time.

Understanding the Error: Why Does 3uTools Say "Unable to Request SHSH"?

Before fixing the problem, you need to understand its root cause. The phrase "when new" is the clue here. The error occurs for three primary reasons when a device or iOS version is brand new:

  1. Apple’s Signing Window Isn't Fully Open: When Apple releases a new iPhone (e.g., iPhone 16) or a new iOS version (e.g., iOS 18.0), the signing servers are initially unstable. 3uTools queries Apple’s servers. If the server response is incomplete or rate-limited, the tool fails.

  2. Missing ECID or Device Model in Local Database: 3uTools relies on a local database of device identifiers (Board Config, Model Number). If you connect a brand new device (released within the last 2-3 weeks), 3uTools might not recognize its hardware ID yet, causing it to abort the SHSH request.

  3. ApNonce Collision (New Security on A12+ Devices): For devices with A12 chips or newer (iPhone XS, XR, 11, 12, 13, 14, 15, 16), Apple introduced a nonce-entropy system. When a device is brand new and hasn’t generated enough random nonces, 3uTools fails to match the ApNonce, resulting in an immediate error.
