How to fix some mysterious problems.

I made the mistake of letting iTunes upgrade my iPhone 3gs to the new 6 operating system and have been trying all day (watching and trying to follow the help videos) to fix my phone. Here's the problem, I have tried the "NO SERVICE/Searching..." video, "Hactivation" video, jailbreak videos - tethered and untethered, but my phone always stops (for 3+ min) in the redsn0w jailbreak with the last line reading: dyld: code signature for shared cache failed with errno=7

Your mistake is relying on Youtube for technical info. Youtube is a great source of entertainment, but not much else. Try our iOS 6 jailbreaking guide, making sure you're using the latest (0.9.15b3) redsn0w, have your antivirus disabled/uninstalled (if on Windows) and are running redsn0w as Administrator (if on Windows). If you get errors, report back here with the details and we'll work through it.

Restore again to 6.0.1 (setting up as a new device, not restoring from iTunes backup - you can do that later) and try it. Do you have any antivirus installed (whether active or not)?
