How to Fix the Unable to Request SHSH Error in 3uTools [2025]

Part 1. What does "unable to request Shsh" mean?

The error unable to request SHSH means 3uTools failed to get the SHSH blobs from Apple’s server. These blobs are needed to downgrade or restore your iPhone. This error often happens if the iOS version isn’t signed, your internet connection is unstable, or Apple’s server is down. Checking your connection and making sure the iOS version is still signed can help fix it.

Part 2: How to Fix “Unable to Request SHSH” Error in 3uTools

The “Unable to request SHSH” error in 3uTools usually appears when you're trying to save or downgrade iOS firmware but can’t connect to Apple’s server. This can happen due to internet issues, unsigned iOS versions, or software bugs. Here's how to fix it in a simple, step-by-step way.

2.1.Try iTunes to Restore

3uTools may not be able to request SHSH because of internal bugs or server communication problems. Restoring your device through iTunes or Finder may help resolve the problem. This method is especially useful when facing issues like firmware corruption or device instability.

Step 1: Connect your iPhone, iPad, or iPod to your computer using a USB cable. Step 2: Launch iTunes (or Finder if you're on macOS Catalina or later). Step 3: Select your device when it appears in the interface. Step 4: Click “Restore iPhone” and confirm the action.

Step 5: Wait for the restore to complete, then open 3uTools and try requesting shsh host again.

2.2. Make Sure Your Internet Works

A stable internet connection is essential to download shsh 3utools or communicate with Apple’s shsh host 3utools servers. Poor network connectivity is one of the most common reasons for this error.

Step 1: Restart your modem or router. Step 2: Switch to a different Wi-Fi network or use a wired connection for better stability. Step 3: Disable VPN or proxy settings that might block Apple’s server.

Step 4: Perform a speed test to ensure sufficient upload and download speeds.

Step 5: If the issue persists, try using 3uTools on a different PC or network to rule out local issues.

2.3.Update Your 3uTools App

Sometimes, the error unable to request shsh pops up simply because the iOS version you’re trying to downgrade or restore is no longer being signed by Apple. That’s why it’s important to check Apple’s server status before trying other fixes.

This method only takes a few minutes and helps you avoid wasting time on versions you can’t install anymore.

Step 1: Launch 3uTools on your Windows PC. Make sure your internet is connected.

Step 2: Click the Menu icon (three horizontal lines) in the top-left corner of the window.

Step 3: From the dropdown list, select “Check for Updates.”

Step 4: If a newer version (such as 2.16 or higher) is available, you’ll see an update prompt. Click “Download and Install.”

Step 5: Once the update is complete, restart your computer to apply all changes.

Step 6: Reopen 3uTools and try requesting SHSH blobs again. It should work now without errors.

2.4.Check If iOS is Still Signed

Before blaming your tool or pc when error like cannot get shsh from the server happened, verify Apple’s signing server. When Apple stops signing a firmware version, tools like 3uTools will fail to fetch SHSH blobs no matter what you try. So, the first and smartest move is to check whether your desired iOS version is still being signed.

Step 1: Go to https://ipsw.me. It’s the most reliable site to check real-time Apple signing status for every iPhone, iPad, and iPod model.

Step 2: Choose your exact device model for example, iPhone 11, iPad Air 4, etc. from the list.

Step 3: You’ll see a complete list of available firmware versions.

• A green checkmark means the version is currently signed SHSH requests will succeed.
• A red cross means the version is unsigned SHSH requests will fail.

Step 4: Decide Your Next Move

• Signed: Go back to shsh 3utools and re-request the SHSH blobs. It should work without any issues.
• Unsigned: You cannot fetch SHSH blobs for this version. Your options now are:
• Wait for Apple to release a new firmware.
• Use saved SHSH blobs (if you’ve backed them up).
• Try a downgrade tool like UltFone iOS Downgrade Tool, which can sometimes bypass SHSH verification.
