3utools Error Unable To Request Shsh Hot [top] (2025)

The "Unable to request SHSH" error in 3uTools occurs when the software cannot verify firmware signatures, often because Apple has stopped signing the iOS version [1]. Other common causes include network-level blockage of Apple's servers via firewall, a modified hosts file, or outdated 3uTools software [1]. Solutions include verifying firmware signing status, clearing the hosts file, disabling security software, and using DFU mode [1]. 

2. Observed Behavior

• User connects iOS device in normal or recovery mode.
• 3uTools successfully detects the device model, ECID, and current iOS version.
• Clicking “Save SHSH” or “Get SHSH” starts the request but eventually returns the error.
• No SHSH blobs are saved.
• Internet connection is active; other 3uTools functions (e.g., flash, jailbreak tools) may still work.

Manual Entry: For some devices, copying the EID code from the device information and pasting it into the target field on signature-check sites can help verify if the request is possible. 10 Common Flashing Errors With Solutions - 3uTools 3utools error unable to request shsh hot
