These are instructions on how to downgrade your iPhone 3GS from iOS 6.x to iOS 5.x using saved SHSH blobs and Redsn0w for Mac.

Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the firmware you would like to restore to and the firmware you are current on from here and place it/them in the Pwnage folder.

Extract the RedSn0w zip file by double clicking it.

Step Two
Right click or control-click the redsn0w application from the redsn0w folder we extracted earlier and choose Open from the popup menu that appears.

Step Three
Click Extras from the main menu.

Step Four
Click Even More from the Extras menu.

Step Five
Click Restore from the Even More menu.

Step Six
Click IPSW from the Restore menu, choose the IPSW you would like to restore to from the window that appears, and click Open.

Step Seven
Redsn0w will ask you if you would like to prevent the baseband from being updated. Click Yes.

Step Eight
Redsn0w will inform you that Pwned DFU mode is needed to restore. Click the OK button.

Step Nine
Connect your device, turn it off, and then click the Next button

Step Ten
RedSn0w will now guide you through the steps to get into DFU mode. You can find more help with DFU mode here.

Hold down both the Home button and the Power button for 10 seconds.

Release the Power button and continue holding the Home button until RedSn0w detects the device.

Step Eleven
Your iPhone will now be exploited with limera1n.

Step Twelve
RedSn0w will check Cydia to see if you have the correct blobs saved.

If RedSn0w is unable to find your blobs automatically you can try to click the Remote button to try again or you can click the Local button to search for blobs on your computer.

Step Thirteen
RedSn0w will now prepare a system restore image.

Step Fourteen
Your device will then be restored to the new firmware.

Step Fifteen
You'll be informed when your restore has completed successfully.

Will this work for IPhone4S?

What if you don't have any blobs that will work anywhere? I have one old blob that stats, "cannot be verified" Now what do I do?

You can only restore to a FW which you have blobs saved for. Old Bootrom allows you to more flexibility with other things (e.g. untethered 6.0 jailbreak)

PLEASE... anyone... i keep reading OVER and OVER that if you have an old bootrom 3gs -which I do- that you don't need shah blobs to restore or downgrade. so how do you do this? instructions are nowhere to be found. I have an old bootrom 3gs... for some odd reason, there are no 5.1.1 blobs saved anywhere (i have every other ios blobs showing). HOW do I get 5.1.1 installed on this phone? I've tried restoring directly to 5.1.1 in iTunes (error 1600)... tried using latest Redsnow - ALWAYS asks for shsh even though it sees this as old bottom. WTF?
