What is SHSH and why is it required?

SHSH (Signature Hash) is a cryptographic signature that Apple uses to verify the authenticity of iOS updates. When you update your iOS device, 3utools needs to request an SHSH blob from Apple's servers to validate the update. However, sometimes 3utools may fail to request the SHSH, resulting in an error.

Causes of the "Unable to request SHSH" error

There are several reasons why you might encounter this error:

1. Network issues: Poor internet connectivity or a blocked network can prevent 3utools from communicating with Apple's servers.
2. Apple's server issues: Apple's servers might be experiencing technical difficulties, causing the SHSH request to fail.
3. Incorrect device information: If the device information in 3utools is incorrect or outdated, it may lead to SHSH request failures.
4. Expired or invalid SHSH blobs: If the SHSH blobs stored on your device or in 3utools are expired or invalid, you may encounter this error.

Part 6: Final Summary – What to Do If Nothing Works

If you have tried all nine methods and still face the error, the problem is likely one of these:

1. The iOS version you want is unsigned, and you have no saved blobs. Solution: Flash the latest signed iOS.
2. Your device has hardware damage (NAND, baseband). Solution: Visit a repair shop.
3. Apple’s TSS servers are globally down (rare). Solution: Wait 2–4 hours and retry.

In 99% of cases, unchecking "Retain User Data" or switching to the latest signed iOS will resolve "Unable to request SHSH" immediately.

5. Check Apple’s server status

Sometimes Apple’s signing/gSudo servers are temporarily down.

Fix:

• Wait a few hours and try again.
• Or check sites like Apple System Status for “iOS Device Activation” or “iTunes Store” (SHSH requests go through similar servers).

Fix #10: Check Your Hosts File (Malware/TetherMe)

Some jailbreak tools or anti-revoke software add entries to your hosts file that block Apple’s servers.

• Action:
  1. Navigate to C:\Windows\System32\drivers\etc\
  2. Open the file named hosts with Notepad (as Admin).
