The first step was fine: “Extracting IPSW…” Then: “Sending AppleLogo…” Then came the wall.
If you are still facing this issue, please tell me the exact and the iOS version you are trying to install, so I can check if it is signed.
Older versions of the 3uTools program may fail to parse newer Apple TSS server protocols, requiring a direct update to the tool's framework. error unable to request shsh 3utools 9 updated
This error halts flash processes, prevents firmware signing, and leaves even advanced users scratching their heads. Why does this happen in the latest 3uTools update, and more importantly, how do you fix it?

Users of 3uTools version 9 encounter the error “Error: Unable to request SHSH” when attempting to flash (restore) iOS firmware, downgrade iOS versions, or save SHSH blobs. The error indicates that 3uTools cannot retrieve a necessary cryptographic signature from Apple’s TSS (Time Service Server). This failure halts any firmware operation requiring verification. If you are still facing this issue, please
Modified system files or strict local network firewalls can intercept the verification request sent to Apple's TSS servers.
3uTools cannot reach Apple servers (e.g., firewall, VPN, or unstable internet).
Alternatively, completely uninstall 3uTools and download a fresh copy from the Official 3uTools Website. Why does this happen in the latest 3uTools
A stable connection between your device and computer is essential for the SHSH request to complete.
Antivirus programs, Windows Defender, aggressive firewalls, or altered hosts files can block 3uTools from communicating with Apple's signing infrastructure.
The most common reason is attempting to install an iOS version that Apple is no longer signing. Once signing is closed, a standard restore to that version is impossible without previously saved SHSH blobs. Outdated Software:
Import this verified file into 3uTools and attempt to flash it again. 2. Force Update 3uTools and iTunes Drivers
Follow these solutions in order. Test after each step by attempting to fetch SHSH blobs for a currently signed firmware (check status at IPSW.me).
