Downgrade iOS with Redsn0w
Downgrade iOS with Redsn0w – What iDevices and iOS versions are supported?
Although the Downgrade iOS with Redsn0w might not be a very difficult procedure, you first need to know that iDevice and what iOS version it supports. The first step that you have to do is to save the SHSH blobs of an iOS version that is still signed by Apple. This way you can have a “spot” at this iOS version and you will be able to Downgrade to it whenever you want. The next step is to not only save them to Cydia servers, but save it locally too (To your computer). The best tactic is to ALWAYS save the SHSH blobs of your iOS version, because it might not be jailbreakable at that time, but in future everything can be jailbroken (As history showed us).
