How to Fix 3uTools Error Unable to request SHSH

Have you run into the annoying "Unable to Request SHSH" error in 3uTools? This problem is a common headache for iOS users who want to save their SHSH blobs — an essential step for downgrading or jailbreaking their devices.

In this guide, we'll break down the main reasons why this error occurs and walk you through clear, step-by-step solutions to fix it so you can continue with your iOS downgrade or jailbreak process smoothly.

Part 1. Common Causes for the 3uTools Unable to Request SHSH

The "Unable to Request SHSH" error in 3uTools usually happens for these main reasons:

• Apple Server Issues – If Apple's signing servers are down or overloaded, SHSH requests may fail temporarily.
• Network Problems – Slow, unstable, or restricted internet connections can block 3uTools from reaching Apple's servers.
• Outdated 3uTools Version – Running an older version of 3uTools may cause compatibility problems when requesting SHSH blobs.
• Incorrect Firmware Selection – Choosing the wrong iOS firmware for your device model can trigger this error.
• Device-Specific Restrictions – Some devices may have restrictions that prevent SHSH requests (e.g., beta versions, unsupported models).
• Firewall or Antivirus Interference – Security software can sometimes block 3uTools from making the necessary network requests.

Part 2. Solutions to Fix Unable to Request SHSH in 3uTools

Solution 1: Verify the signing status of the iOS

The most common reason for this error is fundamental to how the process works: you can only save SHSH blobs for an iOS version that Apple is currently "signing." Once Apple stops signing a firmware version (which usually happens shortly after a new one is released), their servers will reject any request for its SHSH blob.

Before anything else, verify the signing status of the iOS version you are targeting.

Step 1: Open a web browser and navigate to a reliable IPSW and signing status website, such as IPSW.me.

Step 2: Select your Apple device (e.g., iPhone) and then your specific model (e.g., iPhone 14 Pro).

Step 3: The website will display a list of firmware versions. Look for the ones with a green checkmark or label indicating they are "Signed." If the version you want has a red 'X' or is marked as "Unsigned," you cannot request the SHSH blob for it, and this is the reason for the error.

Solution 2: Ensure Software is Up-to-Date

In certain situations, outdated versions of iTunes and 3uTools may interfere with the SHSH blob saving process. Therefore, please ensure both your iTunes and 3uTools software are updated to the latest versions.

Case 1: Update 3uTools

Sometimes the "Unable to Request SHS" error occurs because you're using an outdated version of 3uTools. Updating the app can fix bugs and improve compatibility with Apple servers.

Step 1: Open 3uTools on your Windows PC with an active internet connection.

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

Step 3: Select Check for Updates from the dropdown.

Step 4: If an update is available, click Update Now button.

Step 5: After installation, restart your PC, then reopen 3uTools.

Step 6: Try requesting SHSH blobs again — the error should be resolved.

Case 2 Update iTunes

An outdated version of iTunes can interfere with 3uTools' ability to communicate with Apple servers. Updating iTunes often resolves the "Unable to Request SHSH" error.

Step 1: Open iTunes → click Help → Check For Updates. If there is a new version of iTunes. Just click the Download iTunes button to download and install the latest update.

Step 2: After installation, restart your PC/Mac to ensure all updates are applied.

Step 3: Open 3uTools and try requesting SHSH blobs again. The update should resolve connection issues with Apple servers.

Solution 3: Verify Your Network Connection

A stable internet connection is required to communicate with the signing servers. Any interruption can cause the request to fail.

Step 1: Check Your Internet. Ensure your computer has a stable and active internet connection. Try loading a few websites to confirm.

Step 2: Use a Wired Connection. If you are on Wi-Fi and experiencing issues, switch to a wired Ethernet connection if possible. This provides a more stable and reliable link than wireless.

Step 3: Temporarily Disable VPN or Firewall. Security software can sometimes interfere with 3uTools' connection. Temporarily disable your VPN or firewall, attempt to request the SHSH, and then re-enable your security software immediately afterward.

Solution 4: Try Restoring with iTunes or Finder

If 3uTools fails to request SHSH due to internal bugs or connection issues, restoring your device with iTunes (or Finder on macOS Catalina and later) can help. This is also a good fix for problems caused by corrupted firmware or device instability.

Step 1: Connect your iPhone, iPad, or iPod to your computer with a USB cable.

Step 2: Open iTunes (or Finder if you’re on macOS Catalina or newer).

Step 3: Select your device from the sidebar or top menu.

Step 4: Click Restore iPhone (or iPad/iPod) and confirm when prompted.

Step 5: Wait for the restore process to finish.

Step 6: After the restore, reopen 3uTools and try requesting SHSH again.
