Better: I Unable To Request Shsh 3utools Fix
Apple has internal rate limits. If you click "Request SHSH" 50 times in a minute, their server temporarily blacklists your IP address for 15–60 minutes. No tool will work during that time.
Step 1: Update 3uTools to the Latest Beta Do not use the stable version. Go to the official 3uTools forum and download the latest Beta build (v2.70 or higher as of this writing). The beta includes updated Apple certificate chains.
Step 2: Switch the SHSH Server Manually Inside 3uTools:
Step 3: The "Decimal vs. Hex" Conversion i unable to request shsh 3utools fix better
If you want the "better fix", focus on Solution 2 (Hosts File). Most "Unable to request SHSH" errors are caused by a "ghost" host entry left over from previous jailbreak tools that redirects 3uTools away from Apple's servers. Cleaning the hosts file usually resolves the issue immediately.
| Problem | Solution | |---------|----------| | iOS version unsigned | Use newer signed iOS or saved blobs | | 3uTools server issue | Switch to Apple Server in SHSH settings | | Network blocked | Disable firewall/antivirus, run as admin | | DNS problem | Change to Google DNS (8.8.8.8) | | Corrupted 3uTools | Reinstall latest version | | No saved blobs for unsigned version | Cannot fix – you must upgrade to signed iOS |
For users of iPhone XS, 11, 12, 13, 14, 15, 16 (A12–A18 chips), there is a technical nuance that often breaks 3uTools. Apple has internal rate limits
When Apple issues a signature, it is tied to a random number called the ApNonce (Application Nonce). 3uTools sometimes requests a blob with a generic ApNonce, but later when you try to use that blob for a restore, your device generates a different ApNonce. The signature doesn't match. As a defensive measure, Apple's servers may reject 3uTools' request outright if the ApNonce format is incorrect.
The better fix for A12+ devices:
Use blobsaver with "Set ApNonce" enabled, or use a jailbreak to set a generator (like 0x1111111111111111) before saving blobs. 3uTools cannot do this reliably.
Better tool for A12+: shsh.host (another web service) that allows manual ApNonce input. Step 3: The "Decimal vs
For newer devices (A12 and above, like iPhone XS, 11, 12, 13, 14, 15), saving blobs requires a specific random number called the ApNonce. 3uTools often fails to generate or match this correctly, leading to the dreaded error. This is where the "better fix" truly lies.
