Downgrade iPhone 4 / 3GS from iOS 6 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.

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.

Work perfect thank you ..

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

Thank you so much!!! I worked perfectly.

Worked perfectly the first time through. Thanks for the procedures! Glad to be back on iOS 5.1.1.

Works perfectly on iPhone 4! Now back to the 5.1.1. Thank you!!!!!!!!!!

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.

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?

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!

thanx that was great i downgrade my iphone 4 from ios 6 to ios 5.1.1 without any difficulty.thanx buddy you makes it easy

I followed all the steps but when I'm restoring it via iTunes, I get the error 21. I tried it a few times but I always get that error. Am I doing something wrong? :X

Thanks in advance!

this device isnt for the request build please help downgrading ios 6 on iphone 3gs

Ok guys I think I have figured out an extremely easy way to downgrade to 5.1.1 on iphone 4 and 3gs without getting "No Service" msg on the top bar if you have experienced this, also no errors from itunes or going anywhere near itunes for a downgrade, i know heaps of people who have had this problem, feel free to post this on all sites where people are having issues downgrading through itunes or getting no service message

1. download latest red snow

2. download latest snow breeze

3.download 5.1.1 firmware

4.open snowbreeze and click on "Baseband preservation mode" so u dont jailbreak your phone, you just want to restore to original firmware for now, a msg will pop up press yes to proceed

5. continue to build custom firmware

6. once its done open redsnow, but make sure you know where your firmware was saved, it usually starts with snowbreeze........etc mine was usually on the desktop

7. once youve opened redsnow go to extras

8.then click on "Even more" button, make sure your dont upgrade your baseband, preserve it or u'll screw up ur phone!!!!

9. click on restore and follow the prompts

10. once u follow the prompts it will begin to restore your iphone to 5.1.1, once its finished you'll be back to stock firmware, set it up as usual it will have "No Service" initially but once you get to the wifi section of set up click connect through itunes and continue set up or you can proceed with wifi if you want, your service will come up before youve completed setting up your phone

11. Congrats on downgrading your phone with no errors through itunes which is a pain in the ass and getting rid of that shitty ios 6 operating system

If you have any worries or questions let me know,.......btw do not upgrade your baseband through redsnow

then you can jailbreak through absinthe :)
Feel free to email me if you have any problems

Hello,
I update my iphone 3gs from ios 4.2.1 to ios 6.0.1. I am experiencing no service problem. I want to downgrade my ios from 6.0.1 to 5.1.1. I followed the steps exactly as instructed but when I click restore on iTunes it gives back that you have to restore and update to ios 6.0.1. How can I solve this issue?
Thank you

Thanks a lot .. This is a great Method ..
