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

Try changing the USB port you're using. Sometimes, the issue might be related to the USB port.

Below are the most effective solutions, ordered from simplest to most advanced.

If you are an iPhone, iPad, or iPod touch user who enjoys restoring, jailbreaking, or downgrading iOS, you have almost certainly encountered 3uTools. This free Windows-based utility is a favorite among enthusiasts because it simplifies complex tasks like flashing firmware, backing up SHSH blobs, and managing iOS devices.

However, one of the most frustrating roadblocks appears when you try to save SHSH blobs for a new (just-released) iOS version. You click the button, wait a few seconds, and then get the dreaded red error message:
"Unable to request SHSH" or "Get SHSH failed".

Why does this happen specifically when the iOS version is new? And more importantly, how can you fix it?

In this detailed guide, we will break down exactly what SHSH blobs are, why 3uTools fails with new firmware, and step-by-step solutions to resolve the error—even if Apple has just stopped signing the previous version.

The "Unable to request SHSH" error on 3uTools for a new device or new iOS version almost always means Apple has stopped signing that iOS version or the 3uTools database isn’t updated yet. Always check signing status first—if it’s unsigned, no tool can fix it. If it is signed, update 3uTools, switch servers, or manually fetch blobs via a browser-based TSS saver.

For future protection: Save SHSH blobs for every iOS version as soon as you update a new device. That way, even if Apple stops signing, you retain the ability to downgrade using tools like FutureRestore (with limitations).

Stuck at 9%? How to Fix the "Unable to Request SHSH" Error in 3uTools

You’ve got your firmware ready, your device is connected, and you’re set to flash—only for 3uTools to stall at 9% with the frustrating message: "Unable to request SHSH."

This error effectively means the software can't get the "digital signature" it needs from Apple's servers to authorize the installation.

Whether you’re working with a brand-new iPhone 15 Pro or an older model, here is how to bypass this roadblock and get your flash back on track. 1. Update 3uTools (The Most Common Fix)

The most frequent cause for this error on "new" setups is an outdated version of 3uTools that doesn't recognize a newer device or iOS version. Open 3uTools and click Check Update at the bottom right. Ensure you are running the latest version available on the official 3uTools website

Even if you just installed it, check for an update; new patches for SHSH bugs are released frequently. 2. Verify the iOS "Signing" Status

Apple only allows you to install iOS versions they are currently "signing".

If you are trying to downgrade to an older, unsigned version, 3uTools will fail because Apple’s servers will reject the SHSH request.

or the 3uTools "Easy Flash" section to see which versions are highlighted in green (signed) versus red (unsigned). 3. Switch to "iTunes Flash" Mode

If "Easy Flash" keeps failing, users often find success by switching the flashing method within the software. Instead of using the default "Easy Flash," go to the Flash & JB tab and select iTunes Flash

This uses different driver logic that can sometimes bypass the 9% SHSH hang. 4. Check Your Network and Drivers

Since SHSH blobs must be requested from remote servers, any network hiccup will kill the process. Disable VPNs/Firewalls:

These often block the specific ports 3uTools needs to talk to Apple. Repair Drivers: in 3uTools and click on iTunes Utility Repair Driver

. This ensures the connection between your PC and the iPhone is "clean." 5. The Advanced "SHSH Host" Workaround how to fix error unable to request shsh on 3utools when new

If the software still can't fetch the signature automatically, you can try to manually grab an AP ticket. Find your device's in the 3uTools device info panel and copy it. Visit a site like and paste your ID to request the signature manually.

Are you attempting to upgrade to the newest firmware, or are you trying to downgrade to an older version?

The neon glow of Alex’s monitor was the only light in the room at 2:00 AM. On the screen, a progress bar had been stuck at 20% for the last hour. Below it, a bright red error message blinked mockingly: "Unable to request SHSH." Alex was trying to jailbreak a brand-new iPhone.

SHSH blobs were the digital signatures Apple used to approve iOS installations. Without them, Alex could not downgrade or restore the phone to the specific firmware needed for the jailbreak. 3uTools, usually a flawless software for this task, was failing. Frustrated, Alex rubbed his eyes and began to troubleshoot. 🛑 Step 1: The Server Block

Alex knew that 3uTools had to communicate directly with Apple's servers to fetch these signatures. He checked his internet connection. It was perfect. He disabled his computer's antivirus and Windows Defender. He closed his third-party firewall. He restarted 3uTools. He clicked "Fetch SHSH" again. Result: Failed. ⏳ Step 2: The Apple Signing Window The "Unable to request SHSH" error on 3uTools

Alex realized he might be fighting a losing battle against Apple's strict ecosystem. Apple only signs specific iOS versions. If a new iOS update just dropped, Apple stops signing the older versions almost immediately.

He checked the online signing status for his specific iPhone model.

He realized he was trying to request SHSH blobs for an iOS version Apple had stopped signing just two days ago.

3uTools could not magically create a signature that Apple refused to grant. 🔌 Step 3: The Hardware Hiccup

Since the phone was "new," Alex wondered if the physical connection was unstable. He unplugged the cheap, third-party lightning cable. He grabbed an original, certified Apple cable.

He plugged it directly into the back of the motherboard, avoiding the USB hub on his desk.

He put the iPhone into DFU (Device Firmware Update) mode manually. 🎉 The Resolution

With the phone in DFU mode, a certified cable plugged in, and the antivirus turned off, Alex decided to try requesting the SHSH blob for the currently signed iOS version instead of the old one.

He clicked the button. The progress bar moved. 20%... 50%... 80%... and finally, "SHSH requested successfully!"

Alex leaned back in his chair. He couldn't downgrade to the old firmware he wanted, but he had successfully backed up the signatures for the current version. The digital battle was won for the night.

To fix the "Unable to request SHSH" error in 3uTools (often occurring at the 9% mark during flashing), you primarily need to update the software to the latest version or switch flashing modes. This error usually occurs because the tool cannot communicate with Apple's servers to verify the firmware signature for your specific device. Troubleshooting Report: 3uTools SHSH Request Failure 1.
