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The most frequent cause for this error on "new" setups is an outdated version of 3uTools that doesn't recognize a newer device or iOS version.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

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.

Verify if the specific iOS version you want is listed as available for your device. Summary Checklist Why it works Update 3uTools Fixes bugs with new hardware like iPhone 15/16. Check Signing Confirms Apple actually allows that iOS version. Use iTunes Flash Bypasses "Easy Flash" bugs. Repair Drivers Ensures a stable USB connection.

Are you trying to downgrade to an unsigned version of iOS, or just trying to restore the current one? How to Fix 3uTools 9% ERROR Unable to request SHSH Latest Aug 4, 2567 BE —

The error "Unable to request SHSH" in 3uTools (especially on a new device or new iOS version) typically means 3uTools cannot retrieve SHSH blobs from Apple’s servers for that specific device + iOS combination.

Here’s how to fix it:

If 3uTools keeps failing, use the web-based TSS Saver:

If the error persists even for a signed iOS on a supported device, reinstall 3uTools or switch to legacy-iOS-kit (Mac/Linux) for SHSH dumping.

To fix the "Unable to request SHSH" error in 3uTools (often occurring at 9% or when dealing with newer devices/firmware), the primary solution is to update 3uTools to the latest version. This error is frequently caused by 3uTools being unable to communicate with Apple's signing servers due to outdated software or server-side changes. Immediate Solutions

Update 3uTools: Click the "Check Update" button at the bottom-right of the 3uTools window. Many users found that updating to V2.16 or higher resolved the issue for newer devices like the iPhone 8 and 15 Pro.

Check iOS Signing Status: Ensure the iOS version you are trying to flash is still being signed by Apple. You can verify this on sites like IPSW.me or via the official 3uTools firmware check.

Switch Flashing Modes: If "Easy Flash" fails, try using the "iTunes Flash" utility within the 3uTools Flash & JB tab. Some users report this bypasses bugs present in the easy flash module. Troubleshooting Steps Verify Network & Drivers:

Confirm your internet connection is stable, as SHSH requests require a direct connection to Apple's TSS servers.

Go to Toolbox > iTunes Utility > Repair Driver to ensure the necessary Apple mobile device drivers are functioning correctly. Manual SHSH Fetching: Copy your device's EID code from 3uTools.

Visit sh.host.io and paste the EID to manually check for available SHSH blobs.

Physical Connections: Use an original or certified USB cable and try a different USB port on your computer, preferably one directly on the motherboard for better stability. Alternative Tools

If 3uTools consistently fails, consider using iMazing or official iTunes to perform the restore, which can sometimes bypass specific 3uTools communication errors.

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

If you are fully updated but still getting the error, the issue is likely your network environment. 3uTools needs a clean line to Apple's servers.
