Downgrade iOS 6.0.1 to 5.1.1 Using Redsn0w – Full Guide
It has been reported by many users that they encountered a series of issues when trying to downgrade iOS 6.0.1 to iOS 5.1.1, so it is now a good opportunity to give you a glimpse into doing this step by step. Stay tuned for what’s coming up below.
Don’t worry – there is nothing that complicated in what we are just about to do. What is mandatory to have is the RedSnow tool and also to have previously saved the iOS 5.1.1 SHSH blobs. You need the iOS 5.1.1 SHSH blobs in order to perform a successful downgrade.
Let’s have a more thorough revising of what we actually need before we get the party started.
First of all, be aware that the only devices the downgrade from iOS 6.0.1 to 5.1.1 is compatible with are the iPhone 4, 3GS and iPod Touch. Any other device not mentioned will not be able to support the downgrade.
The second box we need to tick is to have the latest version of Redsn0w 0.9.15b3 downloaded and to have also saved iOS 5.1.1 blobs for continuing with the action. It is of no importance if you have saved the blobs via TinyUmbrella or Cydia, as long as you saved them, because having saved the blobs is a mandatory precondition of the downgrade, as we have mentioned straight from the very beginning of the post.
It is also advisable that you should do a backup of the phone before you start – and what is to be noted here is that only the iOS 6.0.1 backups will not work on iOS 5.1.1. Yes, the downgrading process need an iPhone restore, so do perform the backup first.
Now that all of the necessary steps have been revised before actually starting the process, we are all set.
How to Downgrade iOS 6.0.1 to iOS 5.1.1 Using Redsn0w
The first step is to download iOS 5.1.1 firmware, and the second step is to download Redsn0w 0.9.15b3 (we can not proceed without having done this).
As a third step, once you start downloading RedSnow, you must unzip the file and launch it. As an additional comment here, if you have a Mac OS X (Mountain Lion), then you should click Cntrl+Open to launch it and if you have Windows then run RedSnow as Administrator.
The fourth step consists of you going to Extra – Even More once the “red” tool is running.
The fifth step to take is to click the Restore button and then the IPSW button.
You will now see the window that requires you select the iOS 5.1.1 firmware file you’ve downloaded in Step 1 and then click Open. This is step 6.
Then you will see a message that makes you prevent baseband update, and is is here where you must select the Yes option.
As step 8, just place your device into Pwned DFU mode to downgrade iOS 6.0.1. What you need to do for this is to turn off your deice and also connect it to the computer.
Once your device is read by Redsnow, then just click on Next and follow the on-screen instructions. Hopefully no problems arise here (if so, you must check once again how to correctly enter DFU). This is step 9.
As step 10, if all has been done correctly, 5.1.1 blobs on Cydia will be detected by RedSnow. If you notice there is nothing moving, then you need to try again and you will do this by using the Remote button. Otherwise you have saved SHSH blobs locally on your computer – so click Local button and select saved blobs.
The last step in the iOS 6.0.1 downgrading process is represented by when it automatically ends and you will be shown a message informing you that you have just successfully downgraded your device to iOS 5.1.1.
