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:
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.

The "Unable to request SHSH" error on 3uTools typically occurs during the flashing process (often at 9%) because the software cannot retrieve the necessary digital signature from Apple's servers. Core Troubleshooting Steps
If you are using a new version or encountering this on a new device, follow these fixes in order:
Update 3uTools: The most frequent fix for newer devices (like the iPhone 15 Pro) is simply installing the absolute latest version of 3uTools. Older versions may lack support for newer hardware identifiers or Apple's updated server protocols.
Verify iOS Signing Status: Apple stops "signing" older iOS versions shortly after new ones are released. If you are trying to flash a version that is no longer signed, 3uTools will always fail with an SHSH error. Check the current signing status on sites like IPSW.me.
Check Network Stability: A poor internet connection or a firewall blocking 3uTools from communicating with Apple's servers can trigger this error. Ensure your PC has a stable connection and that 3uTools is allowed through your antivirus.
USB Connection: Use an original Apple lightning or USB-C cable and try a different USB port on your computer to rule out data transfer interruptions. Advanced Solutions
If standard updates don't work, community experts suggest these technical workarounds:
To fix the "Unable to request SHSH" error in 3uTools, the most effective solution is typically to update 3uTools to the latest version from the official website. This error often occurs at the 9% or 19% mark of a flash when the software cannot communicate correctly with Apple's servers to verify firmware signatures. Core Troubleshooting Steps
Update 3uTools: Download and install the latest version. This resolves compatibility issues with newer iOS versions and hardware like the iPhone 15 Pro.
Verify Firmware Signing: Ensure the iOS version you are trying to install is still being "signed" by Apple. You cannot request SHSH for versions Apple has closed.
Check Network Connection: Ensure your computer has a stable internet connection to reach Apple’s servers.
Try "iTunes Flash" Mode: Some users find success by switching from the "Easy Flash" tab to the iTunes Flash utility within 3uTools. Advanced Manual Fixes
If standard updates don't work, manual SHSH retrieval may be necessary:
Use an SHSH Host: Visit external sites like shsh.host to manually request an AP ticket.
Input Device Identifiers: Copy your device's ECID or EID from 3uTools and paste it into the SHSH host website to fetch available signatures.
Check Third-Party Tools: For persistent issues with older or specific devices, tools like iMazing are sometimes cited as alternatives for repairing or restoring devices stuck in this state.

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:
SHSH blobs are digital signatures Apple issues to authorize a specific iOS version installation on a specific device. When you restore or flash firmware, 3uTools tries to request these blobs from Apple’s servers.
The error "Unable to request SHSH" means 3uTools failed to get a valid signature. For a new device or new iOS version, this is almost always due to Apple no longer signing the iOS version you’re trying to install.
The "Unable to request SHSH" error on 3uTools is annoying, but rarely fatal to your jailbreaking plans.
Final Recommendation: Always ensure you are running the latest beta or stable version of 3uTools. If the error persists, turn off your firewall and wait a few hours. The issue is rarely on your end; it is usually just a synchronization lag between Apple's release and the tool's compatibility.
The "Unable to request SHSH" error in 3uTools typically occurs during the flashing or restoring process when the software fails to retrieve a signed hash (SHSH blob) from Apple's servers. This is most common when using new or recently released iOS versions that require the latest software protocols for authentication. Immediate Solutions for New Versions
If you are seeing this error while working with a new device or the latest iOS release, follow these steps first:
Update 3uTools to the Latest Version: This is the most effective fix. New iOS versions often require updated algorithms in 3uTools to communicate with Apple's servers. Click "Check Update" at the bottom right of the 3uTools interface and install any available updates.
Verify Apple Signing Status: Apple only provides SHSH blobs for iOS versions they are currently "signing". If you are trying to restore to an older version (downgrading) that Apple has stopped signing, the request will always fail.
Check Network Stability: A stable internet connection is required to fetch these digital keys from Apple. If your connection is unstable, 3uTools may timeout. Try disabling any active VPNs or proxies that might interfere with server communication. Advanced Troubleshooting Steps

How to Fix 3uTools 9% ERROR Unable to request SHSH Latest
The "Unable to request SHSH" error in 3uTools typically occurs during the early stages of a flash (often at 9%), signaling that the software cannot obtain the necessary digital signature from Apple's servers to authorize the firmware installation. Common Fixes for SHSH Request Errors
Update 3uTools: This is the most effective solution for new devices. Older versions may not support the latest hardware or Apple's updated security protocols. Download the newest version directly from the 3uTools official site.
Check iOS Signing Status: Apple only signs specific iOS versions. If you are trying to flash an older, "unsigned" version of iOS, the request will fail because the servers will no longer provide the SHSH blobs.
Verify Network Stability: An unstable internet connection or a firewall blocking 3uTools can prevent it from reaching Apple's servers. Ensure your network is active and consider disabling security software temporarily.
Use iTunes Flash Mode: If "Easy Flash" fails, some users find success by switching to the iTunes Flash utility within the 3uTools Toolbox, which uses different drivers for the process.
Repair Drivers: Use the iTunes Utility in the 3uTools Toolbox to "Repair Driver." Corrupted or outdated drivers can cause communication breakdowns between your device and the PC.
