To fix the "Unable to request SHSH" error on 3uTools, primarily ensure you are using the latest version of 3uTools and attempting to flash a signed iOS firmware
. This error commonly occurs when Apple's servers are no longer authorized to provide signature hash blobs (SHSH) for an older or unsigned version of iOS. Common Solutions Update 3uTools:
Many users report that simply updating to the newest version from the official 3uTools site
resolves the issue, especially if the error occurs around the 9% mark during flashing. Use "iTunes Flash" Mode: Instead of using "Easy Flash," switch to the iTunes Flash utility within 3uTools. Some users on

To fix the "Unable to request SHSH" error in 3uTools, you primarily need to ensure that the iOS version you are trying to flash is still being signed by Apple or that you have valid local SHSH blobs saved for that specific version. Why the Error Occurs
The SHSH (Signature HaSH) blob is a digital signature that Apple uses to verify and authorize iOS installations. If Apple has "closed the window" or stopped signing a specific firmware version, their servers will refuse to provide the SHSH blobs required for the installation to proceed. Common Fixes and Solutions Check iOS Signing Status : Open the "Flash & JB"
tab in 3uTools and look at the firmware list. Only versions with a Close 3uTools completely
or a checkmark are currently signed and can be flashed without saved blobs. Update 3uTools

at the bottom right of the 3uTools interface to ensure you are on the latest version. Switch to "iTunes Flash" Mode
: Some users report that the "Easy Flash" method fails while the "iTunes Flash"
utility within 3uTools successfully bypasses certain request bugs. Verify Network & Hardware
Ensure your internet connection is stable and not blocked by a firewall or VPN. Try a different certified lightning cable
and a different USB port on your computer, as faulty hardware often interrupts the "Querying for SHSH" stage. Use DFU Mode
