How to Fix the “Unable to Request SHSH” Error on 3uTools When on Top Firmware
The “Unable to request SHSH” error in 3uTools is a common frustration for iOS users trying to save or use SHSH blobs, especially when their device is running the latest (top) firmware version. This error typically arises because Apple has stopped signing the firmware you are trying to request, or because 3uTools itself is struggling to communicate with Apple’s signing servers. Since you cannot downgrade to an unsigned firmware without saved blobs, the solution requires a change in strategy rather than brute force. Here are the most effective fixes.
1. Understand the Signing Window Constraint The most frequent cause of this error is simple: Apple is no longer signing the iOS version you are requesting. When a device is on the “top” (newest public) firmware, Apple often stops signing the previous version within days or weeks. 3uTools will return “Unable to request SHSH” because no valid signature exists for that iOS build. Before any troubleshooting, verify current signing status on sites like ipsw.me. If the firmware is unsigned, you cannot request SHSH blobs for it—period. Your only option is to save blobs for the currently signed top version for future use.
2. Switch to Manual Request Mode 3uTools’ automatic SHSH fetch often fails with the top firmware due to server timeouts or cached data. To bypass this:
3. Use an Alternative Server or Tool 3uTools may have outdated or overloaded proxy servers. Switch the SHSH server:
4. Disable Antivirus and Firewall Temporarily Security software can block 3uTools’ ability to reach Apple’s servers, especially on top firmware where network handshakes are strict. Temporarily disable Windows Defender or any third-party firewall, then retry the SHSH request. If it works, add 3uTools to your antivirus whitelist.
5. Reinstall or Update 3uTools An outdated 3uTools client may have broken API endpoints. Uninstall, then download the latest version from the official site. Older builds often fail to request blobs for new iOS versions because Apple changes its TSS protocol. A fresh install resets corrupted configuration files.
6. Last Resort: Fetch via Jailbreak (If Available) If your top firmware is jailbreakable, use a tool like System Info (from Cydia/Taurine) or Blobsaver on a PC. These utilities can dump the device’s current APNonce and request blobs while the device is running, bypassing 3uTools’ generic request method.
Conclusion The “Unable to request SHSH” error on top firmware usually signals either an unsigned iOS version, a server communication issue, or a tool limitation. The most reliable fix is to verify signing status, switch to manual request mode, or use a dedicated web-based saver like TSS Saver. Avoid relying solely on 3uTools for critical blob saving—always cross-check with alternative methods. By understanding that Apple’s signing window is the ultimate gatekeeper, you can stop chasing a dead end and focus on saving blobs for the currently signed version while you still can.
The "Unable to request SHSH" error in 3uTools typically occurs at the 9% mark during a flash or restore process. It usually means the software cannot communicate with Apple's signing servers to verify the firmware version you are trying to install. Common Fixes
Update 3uTools: This is the most successful solution. Older versions of 3uTools may have bugs or outdated server links that prevent SHSH requests. Visit the official 3uTools Download Page to get the latest version.
Check iOS Signing Status: Apple only "signs" certain firmware versions (usually the most recent). If you are trying to downgrade to an older, unsigned version, 3uTools will fail because Apple's servers are no longer authorizing those installs. You can check current signing status at IPSW.me.
Switch to "iTunes Flash" Mode: Some users on Reddit found that switching from "Easy Flash" to the "iTunes Flash" tab within 3uTools bypasses this specific bug.
Verify Your Network: Ensure your computer has a stable internet connection. Firewall or antivirus settings can sometimes block the request to gs.apple.com (Apple's signing server).
Hardware Check: If the error persists or occurs at different percentages (like 19% or 20%), it may indicate a hardware issue with the device's NAND (storage) chip.

Relaunch the application and try the flashing process again. 2. Switch Flashing Modes If the "Easy Flash" mode fails, try using the iTunes Flash utility within 3uTools. Navigate to the Flash & JB iTunes Flash instead of the default "Easy Flash" option.
Ensure that iTunes is closed on your computer before starting, as it can interfere with the 3uTools connection. 3. Verify Firmware Signing Status
You can only request SHSH blobs for firmware versions that Apple is currently "signing". If you are trying to
to an older iOS version that is no longer signed, the request will fail because Apple's servers will not issue the necessary certificate. Check sites like
to see which versions are still signed for your specific device. 4. Troubleshoot Connection and Hardware Check Internet Connection:
Since 3uTools must contact Apple’s TSS servers to request the SHSH, a stable internet connection is required. Hosts File: Ensure your computer's file is not blocking Apple’s servers (e.g., ://apple.com
). Remove any lines related to Apple if you have previously used tools for bypassing or older downgrades. USB Port/Cable:
Try a different USB port (preferably on the back of a PC) or an original Apple MFi-certified cable.
