How to Fix dyld: code signature for shared cache failed with errno=7 During Jailbreak with Redsn0w
This is a common error encountered by users but it can be fixed quite easily.
You are getting that error because you are supposed to point redsn0w at the firmware your iPhone is currently on.
For example, if your iPhone is currently on iOS 5.1.1 or 5.0.1, pointing redsn0w to a different iOS version will cause this error.
You must point redsn0w to the same iOS version and also you must NOT point it to custom iOS (IPSW), only original firmware can be processed by redsn0w.
1.Go to Extras
2. Select IPSW and select the original IPSW you have downloaded.
3. Proceed with next steps.
Here are the latest redsn0w download links:
- redsn0w 0.9.15b3 (OS X — use Ctrl-Click->Open if on Mountain Lion for now)
- redsn0w 0.9.15b3 (Windows — run in Adminstrator Mode)
