Downgrade iPhone 4 / 3GS from iOS 6 to iOS 5.1.1

Do you miss Google Maps? Did the iOS 6.0 update shorten battery life on your A4 device? Whether you upgraded by mistake, or you're just looking to bring back the older firmware, now you can downgrade your iPhone 4 or iPhone 3GS to iOS 5.1.1. The following iOS downgrade instructions work on most A4 devices, including the iPod touch 4G.

downgrade A4 to iOS 5.1.1

Now that Apple has stopped signing older firmware, you must have your SHSH blobs saved for iOS 5.1.1 for this procedure to work properly. Downgrading will also require that you have the appropriate IPSW firmware file downloaded to your computer. You can grab iOS 5.1.1 for the iPhone 4 here, or for the iPhone 3GS at this link. Make sure you know where this IPSW file is saved before starting the instructions below.

1. Download redsn0w 0.9.14b2 from iPhone Dev-Team.

2. If your SHSH blob is stored on your computer, put it in the same folder as the iOS 5.1.1 IPSW file. If your SHSH blob is stored on Cydia, then proceed to step 3.

3. Put the iPhone you are downgrading from iOS 6 to iOS 5.1.1 into DFU mode.

4. Open redsn0w and navigate to Extras -> SHSH blobs -> Stitch.

5. Select IPSW and choose the iOS 5.1.1 IPSW file for your iPhone.

6. If your SHSH blobs are stored on the computer, select Local and choose the iOS 5.1.1 SHSH file. If your SHSH blobs are stored on Cydia, select Cydia.

7. After your SHSH blob and IPSW firmware files are located redsn0w will proceed to stitch them together. This makes it possible for the new custom firmware to be installed without Apple signing iOS 5.1.1 for your device.

8. When redsn0w is finished stitching, go back twice and select Pwned DFU.

9. Open iTunes on your computer. The iPhone should appear as a device in recovery mode. While holding down the Option key on the keyboard, click the Restore button. Choose the stitched custom firmware file redsn0w just created.

10. Wait for iTunes to restore your iPhone. An unknown error (-1) dialog box might appear.

11. Go back to redsn0w and navigate to Extras -> Recovery fix. Put your iPhone into DFU mode again.

12. Once redsn0w finishes with the recovery fix, your iPhone will be successfully downgraded to iOS 5.1.1.


Hey. thanks for short informative post but I get 3194 error from iTunes with my 3GS ( after redsn0w fix iphon boots back to ios6) then i used tinny umbrella 6.00.01 (i have shsh blobs) with enabled and disabled server and it resulted with 1600 and 1601 respectively. I get 3194 with clear host file by the way. Any Ideas.

It worked eventually. I used wrong version of redsn0w. I steal can't activate though.

Okay so i downgraded my ipod touch to 5.1 and it works great but i need help jailbreaking. i dont have a homebutton and i cant use a dfu ipsw cause itunes doesnt restore ios 5.1 unless its stitched so i did and i get error 1604. please help me

hii there does any one here got SHSH blob 5.1.1 for 3gs store in mac or win?? im update my ios but did't backup my shsh 5.1.1.... plezzz help me...need it badly for downgrade... in my cydia only got shsh 4.1......thx..

I didn't even know I had to save SHSH blobs but I completed all of the steps (minus SHSH blobs) and my phone still downgraded. Thanks for the post. I just don't think that you have to save the SHSH blobs because I didn't even know what they were until I read this post. All I did was stitch from Cydia. Does anyone know if the SHSH blobs are automatically stored to Cydia? If not, I think they do back them up.

first of all you must have tiny umbrella and follow this video http://www.youtube.com/watch?feature=player_embedded&v=3CJTjwUF7oE#!

First of all your guy have to follow this video How And Why to Save SHSH Blobs With Tiny Umbrella

Thanks for the tutorial
I'm trying to downgrade an iPad2, but still no luck.
I always get this error message:
"cannot close compressed IPSW"
I tried stitching, restoring it, it always ends up with that error.
Any suggestions?

EVERY TIME I try to restore to 5.1.1 (currently on 5.1.1) I get error 1600 when restoring. First error to occur was 3***
I've followed instructions to the bone, even tried other various methods.
Shsh is saved for 5.1.1, currently have a window up looking at it (3758600416652-iPhone3,1_5.1.1_9B206.plist)
Also stitched it to the 5.1.1 firmware
Currently in pwn dfu mode.
All I want to do is clean restore. Any help would be greatly appreciated.

Also should note it's AT&T (GSM I believe)

What happens if you bought a iPad 3 that already had 6.0 installed? No SHSH files to be found! I can't downgrade from 6.0 to 5.1.1! Not that easy! Any suggestions! Is it possible?

same question, if I (and Cydia) don't have my 5.1.1 blobs and the iOS6 is already on the device is it possible to downgrade? Please can some expert answer so I could stop googling :]

no you can't it will be impossible unless a worm or high level boot exploit found which i think not possible atm , you can only now save your 6.0 blobs because apple stoped sign older ios in ur case apple stopped to sign 5.1.1

I have jailbroken and unlocked iphone 3gs on 4.1 and want to update it to ios 5.1.1! will this process work in my case? I have SHSH saved on my cydia!

Hey man, I am in a situation like yours....

I also have an iPhone 3GS with iOS 4.1 and I'd like to update it to iOS 5.1.1 but I have no SHSH files...

If you found a solution please post it here...
