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The most frequent cause for this error on "new" setups is an outdated version of 3uTools that doesn't recognize a newer device or iOS version.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 how to fix error unable to request shsh on 3utools when new
. 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.

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 —
Fixing the "Unable to Request SHSH" error in 3uTools can be frustrating, especially when you are working with a brand-new device or a freshly released iOS version. This error typically occurs when 3uTools cannot communicate effectively with Apple's servers or when the specific SHSH blobs you are requesting are no longer being signed.
To resolve this issue, follow these troubleshooting steps in order. Verify Apple's Signing Status
The most common reason for this error is that Apple has stopped "signing" the firmware version you are targeting.
Apple only allows SHSH requests for currently signed iOS versions.
Check sites like IPSW.me to see if the firmware is still green (signed).
If the version is "Unsigned" (red), you cannot request new SHSH blobs for it. Check Your Network Connection
3uTools requires a stable connection to both its own servers and Apple’s TSS (Teleservices Software Server).
Disable VPNs: Virtual Private Networks can interfere with the specialized handshake required for SHSH requests. Stuck at 9%
Check Firewall Settings: Ensure your Windows Firewall or third-party antivirus isn't blocking 3uTools.
Switch Networks: If you are on a restrictive office or school Wi-Fi, try using a mobile hotspot. Update 3uTools to the Latest Version
Older versions of 3uTools may use outdated server addresses or protocols that Apple has since changed. Open 3uTools on your PC.
Click the Check for Update button at the bottom right corner.
If an update is available, install it and restart the program before trying the request again. Use DFU Mode for the Request
Sometimes, 3uTools struggles to grab the ECID or necessary device identifiers while the phone is in regular "Normal" mode. Connect your device to your computer.
Manually put your iPhone or iPad into DFU Mode (the steps vary by model).
Once 3uTools detects a device in DFU mode, navigate to Smart Flash > Download SHSH and try the request again. Manually Enter ECID
If the "New" device status is preventing 3uTools from reading your info automatically, you can try a manual approach. Go to the Device tab in 3uTools. Locate your ECID and copy it. Navigate to the Flash & JB section, then SHSH (Blobs).
Use the "Query SHSH" feature and manually paste your ECID if prompted, ensuring the model identifier matches your device exactly. Common Workarounds If the error persists despite the steps above:
Try a different USB port: Use a port directly on the motherboard (back of the PC) rather than a front-panel port or a hub.
Use an official Apple cable: Cheap third-party cables often fail during data-heavy tasks like SHSH requests. Wait 1–2 weeks for 3uTools to update its device database
Reinstall iTunes: 3uTools relies on certain drivers bundled with iTunes. Uninstalling and reinstalling the latest version of iTunes can often repair broken driver links.
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.

SH.host Verification: For some specific device models, you may need to copy your device's EID code and verify the firmware availability on third-party verification sites like SH.host to ensure the version you have matches the expected signature.
Hardware Check: If the error persists across different computers and cables, it may indicate a hardware issue with the device's storage (NAND) or connection port.
Sometimes the error occurs because the device isn't in the right state for the request.
Below are the most effective solutions, ordered from simplest to most advanced.
Ironically, the latest version of iTunes (12.12 or 12.13) sometimes has broken API calls for brand new devices. The older version 12.10.11 is known to be more stable for SHSH requests.
Steps (Windows only):
iTunes 12.10.11 from reputable archive sites (e.g., FileHippo).
