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.

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.

Cheap third-party cables often fail during data-heavy tasks like SHSH requests.

To resolve this issue, follow these troubleshooting steps in order. Verify Apple's Signing Status

Manually put your iPhone or iPad into (the steps vary by model).

Check sites like IPSW.me to see if the firmware is still green (signed).

Apple only allows SHSH requests for currently signed iOS versions.

If you are on a restrictive office or school Wi-Fi, try using a mobile hotspot. Update 3uTools to the Latest Version

Once 3uTools detects a device in DFU mode, navigate to 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 tab in 3uTools. Locate your ECID and copy it. Navigate to the Flash & JB section, then SHSH (Blobs) .
