How To Fix Error Unable To Request Shsh On 3utools When New 【720p — 480p】

Before fixing the problem, you need to understand its root cause. The phrase "when new" is the clue here. The error occurs for three primary reasons when a device or iOS version is brand new:

This is a critical point. If Apple stopped signing the version before you tried to save blobs, you cannot retrieve them from Apple’s servers. No tool—3uTools, TSS Saver, or even Apple’s internal tools—can generate SHSH for an unsigned version.

However, if you have a jailbroken device, you can save onboard blobs (blobs currently on your device) using: how to fix error unable to request shsh on 3utools when new

But for a new iOS version that you haven’t installed yet, you must save blobs while Apple is still signing it. That window is typically 1–2 weeks for major updates, and 2–3 days for minor patches.

Golden rule: Save SHSH blobs within 48 hours of a new iOS release for best results. Don’t wait. Before fixing the problem, you need to understand

Before anything else, check if the iOS version you want is still being signed.

If unsigned: You cannot fix this. Apple has permanently closed the window. You must install the latest signed iOS version instead. 3uTools cannot bypass Apple’s signature check. This is a critical point

If signed: Proceed to the next fixes.

If the issue persists, try using a different tool like tsschecker (for Windows and macOS), which is another popular utility for requesting SHSH blobs.
