How to Downgrade you iPad 2 from iOS 6 to 5.1.1 (or other firmware)

Ok this is one of those things I’ve been personally looking for.
Today’s version of Redsn0w will finally allow you to downgrade your iPad 2 from Apple’s latest iOS 6 firmware to 5.1.1 or below providing you meet the requirements.

This is a pretty complex tutorial but if you want your jailbreak back on your iPad 2 then this will be the only way to do it.

Lets first look at the requirements. In order for you be eligible you need to have BOTH SHSH’s saved for your iPad 2. Meaning you will need at least 1 copy saved for 4.x and 1 copy saved on 5.x, this is the ONLY way to downgrade from iOS 6.0 on your iPad 2. To check if you qualify, the easiest way is to start TinyUmbrella and have it do a pull of all the avaialble SHSH blobs from the Cydia Server, this is pretty simple check out tutorial on how to do this here.

That however is not the only requirment. If you are trying to restore to 5.x, the only people who qualify here are the ones that did the update using iTunes and not using the OTA (Over the Air) update. If you did, you’ll get errors… this happened to us, so we’ll show you your options on what you can do from the to keep downgrading.

Ok Lets start up.

Step 0 – Download All the files required.

  • iOS Firmware you want to downgrade to (* + a 4.x firmware if you are restoring to 5.x, it will require both the firmware you are downgrading to along side of the 4.x firmware to make the downgrade happen.)
  • Redsn0w from here

* iTunes is not used for this downgrade

Step 1 – Start Redsn0w

Step 2 – Check what your downgrade options are, Click Extras

Click SHSH blobs

Click Query

Give it a second, allow Redsn0w to connect to Cydia and pull the available SHSH blobs for your device. As you can see it’s found 5.1.1, 5.0.1, 4.3.5, 4.3.4, and 4.3.3 for my device.

So this means I can downgrade to any of those firmwares, correct ? Well let’s find out. Lets try to downgrade to 5.1.1 first.

Step 3 – Head Back to Extras

Click Even More

Click Restore

Click IPSW

Now select the 5.1.1 firmware you downloaded.

Step 4 – You should get a warning like this stating “To restore to firmware 5.1.1 on the iPad2, the IPSW of any iOS 4.x firmware for which you have saved blobs is also required.”

At this point click ok, and select the downloaded 4.x firmware from Step 1.

Step 5 – Now you’ll get a message stating your device is going into recovery mode.

Step 6 – Now you can choose to use local or remote shsh blobs, I’m going to select remote as I don’t have them local on my computer.

Step 7 – Now, put your device into DFU mode and click OK.

When you successfully put your device into DFU mode, you’ll see Redsn0w start to do it’s thing.

If all goes according to plan, your device should now start downgrading to iOS 5.1.1

But Wait !

What’s this ?

This is an error a few might encounter. Who does it effect ? Well if you’ve updated to iOS 5.1.1 OTA (over the air) or if you got a factory supplied iPad 5.1.1 then you would also get this error.

But, You can see that I have my SHSH back to 4.x meaning I definetelly did not get it from the factory with 5.1.1. Meaning I probobly did do the update OTA for this iPad 2 and now can’t restore it to 5.1.1

So now what ? Does this mean I can’t downgrade ? Not exaclly. Since iOS 5, Apple introduced APTtickets along side of the SHSH requests for devices to downgrade. Meaning that without the APT ticket you’re device will not be able to be downgraded to iOS 5. And anyone who’s upgraded using the OTA method or got a factory fresh 5.1.1 device, didn’t get a APTticket generated. Meaning I can’t downgrade to 5.1.1 But wait I had more SHSH on file right ?

Since Apple didn’t require APTtickets in iOS 4, maybe I can restore to that… lets find out.

Step 1 – Start Redsn0w

Step 2 – Click Extras

Click Even More

Click Restore

Click IPSW

Step 3 – Now I’ll select the 4.3.3 firmware becasue i know i have the SHSH saved for that as well.

Step 4 – Now you’ll get a message stating your device is going into recovery mode.

Step 5 – Now you can choose to use local or remote shsh blobs, I’m going to select remote again as it’s quicker.

Step 6 – Now, put your device into DFU mode and click OK.

When you successfully put your device into DFU mode, you’ll see Redsn0w start to do it’s thing.

Well look at that ! Restored just fine. Now Looking at my iPad it looks like it’s in recovery mode. I quickly started iTunes up and reconnected the iPad and it booted to the fresh install iOS 4.3.3 screen.

Knowing the power of JailbreakMe, i connect to wifi, head to http://jailbreakme.com and install cydia right from the safari browser.

Now restored and fully jailbroken :)
