These are instructions on how to downgrade the firmware of your iPhone 4s using RedSn0w for Mac.

In order to continue you will need to have SHSH Blobs saved for the lower firmware version you are downgrading to. You can use RedSn0w or TinyUmbrella to save your SHSH blobs. Also make sure you have performed a backup of your device using iTunes.

You may want to do this to downgrade from iOS 5.1.x to iOS 5.0.1 for jailbreak.



Step One
Create a folder called Pwnage on your desktop and download the following items into the folder.
- The latest version of RedSn0w
- The current iOS firmware (iOS 5.1.1)
- The older firmware you want to downgrade to (iOS 5.0.1)

Double click the RedSn0w archive to extract it.

Step Ten
You will be warned that if you continue your baseband will be updated to the latest version. If you want the best chances of unlocking your phone in the future you should not continue. If you do not care about an unlock click the YES button.

Step Twelve
You must now select your blobs for restore. You can choose to specify local blobs or remote blobs.

REMOTE BLOBS
- Choose this option if you previously saved your blobs with RedSn0w and they were stored on the Cydia server. This is the easiest option if it's available to you.

LOCAL BLOBS
- Choose this option if you previously saved your blobs with TinyUmbrella or you used RedSn0w but did not let Cydia save a copy of your blobs.
- After clicking Local you will be prompted to select your saved blob file for the firmware you are downgrading to. If you used TinyUmbrella, simply press COMMAND+SHIFT+G, input ~/.shsh, and click Go to navigate to the folder with your saved SHSH blobs. Select the file that matches the ECID displayed in RedSn0w and the firmware version you are downgrading to, then click Open.

Ok, I have in iPad 3, but it came with iOS 5.1, so I don't have shsh blobs... There's a way where I can download some knowing it will work on my iPad? Thanks
No

Cant you read dude? you can't downgrade any device without saving your blobs Period. These is no jailbreak for 5.1 you are going to have to wait until POD2 releases his jailbreak For now you can NOT downgrade your IPDA3 or for anyone that doesn't have their Blobs saved.. You better save your blobs right now with tiny umbrella just in case apple releases 5..1.2

Yes, so long as you have the SHSH blobs for the older firmware saved.

ok it seems it was forgotten about but will be in the next update. "Update #1: We accidentally left out one of the two flavors (“9A406”) of 5.0.1 for iPhone4S. It’ll be in the next update, but in the meantime check if Cydia or TU saved your blobs for the other 5.0.1 for iPhone4S (“9A405”)."

DGUNZ - May 12, 2012 at 12:02am
It works, you have to first upgrade to 5.1.1, then when in redsn0w you have to use 5.0.1 (9A405) not (9A406).

Does this applies for iPad2 as well?

"Starting with redsn0w version 0.9.11b1, those with newer devices (iPad2, iPad3, and iPhone4S) can join the downgrade fun too! In a radical departure from previous versions of redsn0w, it now directly supports restoring IPSWs to your device. The first use of this new feature implements a hack that allows A5 downgrades without a bootrom-level exploit."
