Update 1: If the below guide stuck with you, try to downgrade from iOS 4.3.5 to 4.3.3 without SHSH blobs - Click Here.
Today Apple has released iOS 4.3.5 for iPhone, iPod touch, iPad and Apple TV 2G to fix security vulnerability with certificate validation issue. Now, if you have saved SHSH blobs for iOS 4.3.4, 4.3.3, 4.3.2 or 4.3.1, you will be able to downgrade from iOS 4.3.4 to anyone of them.
Note: iPad 2 (3G models) are not supported on this tutorial as its baseband can't be downgraded so far.
Step 1: Download the required IPSW file to which you want to downgrade to, the links are given below for your convenience:
Now you can jailbreak your iPhone, iPod touch or iPad, just go to our Jailbreak Wizard - Click Here.Step 2: Once you’ve downloaded the required IPSW file, its time you put your iPhone, iPad or iPod touch into DFU mode. The steps are as follows:
At this point, your device’s screen should be off, if that’s so, then you’ve successfully put your device in DFU mode. If iTunes logo shows up, you’re in Recovery Mode, NOT DFU mode.
- Connect your iPhone, iPad or iPod touch to your PC or Mac.
- Turn your device off.
- Now launch iTunes.
- Hold down the Power button and the Home button simultaneously for 10 seconds.
- After 10 seconds, release the Power button but don’t let go of the Home button, your computer should detect a new USB device.
- At this point, iTunes will also recognize your device, whether its an iPhone, iPad or iPod touch.
Step 3: Here comes the tricky and the most important part, you’re going to fool iTunes into thinking that its in contact with Apple’s servers, whereas we’re going to change that to Saurik’s server. In order to do this, follow the steps given below:
Windows users:
Navigate to C:\Windows\System32\drivers\etc\ and locate the file named as “hosts”.
Mac users:
Mac users can access the “hosts” file by navigating to “/etc/” folder, which can be found through Go > Go to Folder from within Finder.
If you’re on Windows, then open the “hosts” file in Notepad. If on a Mac, then open the “hosts” file in TextEdit, and add the following line at the end:
74.208.105.171 gs.apple.comRefer to the screenshot below if you’re having confusion:
Just save the file and close Notepad or TextEdit, and you’re all set for the downgrade.
A quick note for Windows 7 and Vista users: Start Notepad with “Administrator privileges”, that can be done by right-clicking the Notepad app, and there you will see the “Administrator privileges” option, simply click and launch.
A quick note for Mac OS X users: While saving the host file on your Mac, you should have complete read and write privileges in order to make changes. Getting a permission error? A simple workaround is to copy the host file to your Mac’s desktop, from there make the changes in TextEdit, save the file, and copy it back to the original location, and replace the original host file with the one which you just created.
Step 4: Launch iTunes, choose your device from the left sidebar. Hold down the left “Shift” key if you’re on Windows or hold down the left “alt” key if you’re on a Mac and click on “Restore”, do not click anything else! A new window will pop up asking you for the location of the IPSW file.
Navigate to the desired firmware to which you want to downgrade to, in this case it can be either iOS 4.3.3, 4.3.2, 4.3.1, 4.3 or 4.2.1. Once you find the required IPSW file, click “Open” and let iTunes do its thing.
In a matter of few minutes, iTunes will install the version of iOS which you directed it to install. At this point you should see a progress bar on your device, everything is automated, therefore don’t do anything silly. Your device will reboot automatically when everything is done.
In some cases, iTunes will throw 1013 error, ignore it, its perfectly normal when downgrading. At this point, your device will be in Recovery Mode with your desired version of iOS fully installed.
You should see a screen like the one below:
Its quite simple to get out of Recovery Mode, simply down this nifty program called TinyUmbrella (Windows, Mac) along with Fix Recovery (Windows, Mac).
Once you’re done downloading TinyUmbrella, launch it, and then click on the “Exit Recovery” button. In a matter of seconds, your device will boot up normally.
Once you’re done with this, the last thing you’re going to do is remove the line you added to the “host” file in step 3, which is 74.208.105.171 gs.apple.com in order to receive updates from Apple’s servers normally.
For iOS 4.3.4 jailbreak - Click Here.

help i get 16XX error when its preparing ipad 2 for restore
Not working, tried on MAC and windows, it just says "This device isn't eligible for the requested build"
this screwed up my iphone i cannot find the hosts folder
Hi, I've followed this tutorial down to the letter... I continue to get an error "The iPad could not be restored. An unknown error occurred (1600)."
I have an iPad two with 4.3.3 firmware, and I have my shah blobs saved. Can you help, please?
I'm in 4.3.4 right now on Ipad2 Wifi, but I don't have SHSH blobs for older firmware, is it possible to save the SHSH of 4.3.4 using tinyumbrella, then proceed to upgrade to 4.3.5 and follow the above tutorial?
or can I downgrade 4.3.4 to 4.3.3 directly without the saved SHSH blobs?
Thanks
doesnt work. get 3194 error all the time
no matter what i do, i always get the 3194 error.
Doesn't work. I am also getting the 3194 error all the time.
how come I always 3194 always. this procedure doesn't work.
error 3194. please help.
If I don't have SHSH blobs saved from 4.3.3 does this work?
not working for me...
stays in recovery mode even after "exit recovery" from tinyumbrella :^((
Thanks for the info. I'm very new to jailbreaking and out of habit I updated to 4.3.4 when prompted. I was using cydia but hadn't save anything. Before I try this, should I still be able to downgrade? Any help would be appreciated! Thanks!
Doesn´t work. Apple are just too good for us. Now I have a bricked Ipad2 and now I have to grovel to my local Apple shop to de and reinstall to 4.3.3 hopefully?
This does not work on iPad 2 4.3.4...you get error code 3194 and tinyumbrella can not find any shsh files. Needs a patch for the iPad 2!!!
yea im stuck im in dfu mode as well
I was one of those who inadvertently updated to 4.3.4 and was really irritated since I had JUST performed a jailbreak on my iPad 2. When I discovered my own error I was really pissed that I missed my JB keyboard! Anyway by following your step by step instructions listed above, I was able to revert to 4.3.3 and successfully used jailbreakme.com to restore my iPad 2 to where it should be. Thank you so much!
When you face a "Recovery Mode" you have to enter the DFU Mode again before and then start using the "Fix Recovery"
The application will start fixing your iPhone , the terminal will start on your iPhone.
When finish your iPhone will start to enter the Activation screen and ready to activate via iTune.
This doesn't work as iTunes always connect to the Apple Update Server.
me to0 error 3194. please help.
DONT CHANGE THE HOST STUFF JUST USE THE START THE TSS IN TINY UMBRELLA AND LEAVE IT OPEN THEN DO THE RESTORE
iTunes will not let you proceed with an IOS update or restore operation on a device without a valid SHSH blob. iTunes typical response if blobs are not valid is the dreaded message "This device isn't eligible for the requested build".
Therefore you cannot restore or downgrade to an older version of iOS without the help of blobs, and so they are very very important!
Error 3194 the I.P. address in the host file you gave is probably incorrect....
UPDATE: I bypassed error 3194 by running TSS server.. error 1600 pops up next. After doing some research i found a program that supposedly bypasses those errors on iTunes.. iPad 2 isn't supported though. I ran the program anyways and its a no-go. Out of fear of bricking the iPad I'm restoring to my original back up. This tutorial isn't entirely accurate. unless im missing something...
did not work
When I go to restore in iTunes, in the search window I cannot find any files with the .ipsw subfix to use for restoring. I am in the file that I unzipped the downloaded file to. When I open the folder up through windows explorer, I can see several files in it but nothing with an .ipsw subfix. Please someone help.
I have no service now
this downgrading procedures for iphone and ipod touch doesn't and has never worked for me.

how to fix error 3194 ??
Hey guys, can I just ask, hypothetically, what would happen if you used this to downgrade a 3G iPad 2 running 4.3.5? I'm trying to weigh the pros and cons here, my iPad crashed and when i put it in Recovery Mode and connected it to iTunes, it automatically upgraded to 4.3.5 OS. Thanks a lot for your help.
Hey guys.
I was wondering what would happen if I tried to downgrade a 3G iPad 2 running 4.3.5? Would it downgrade but not have a working cellular connection or would it just refuse to downgrade in the first place?
My iPad crashed and when i went to Recovery Mode and hooked it up to iTunes, it updated my OS.

Hi folks,
Had real trouble downgrading to 4.3.3 on iphone 4, but finally made it.
Ignore all the errors. Your device runs the 4.3.3 firmware by the time you get the error on itunes, the trick is to kick the device out of the DFU loop.
I was getting nowhere with the 74.208.105.171 gs.apple.com string in hosts file which is supposedly due to a bug on cydia server, so what I did was I simply left the file open and erased the string in-flight (don't forget to save the file!) after itunes had made initial software checks (approx 1 min into the restore).
Kick the device out of DFU using the fixrecovery43.exe and zlib1.dll (be sure to place both in same folder on your PC/Mac).
Good luck!

Followed the instructions and did it on my dad's iphone 4.3.5 and got it down to 4.3.3 . Thank you.
Just a tip for those trying to downgrade the iPad2 3G from 4.3.5 to 4.3.3 and having the recovery loop issue.
NOTE: Will need savel blob for 4.3.3
Download the 4.3.3 firmware and latest TU.
Connect iPad 2 to computer and load itunes.
open TU ( make sure blob is listed )
close itunes
open hosts file and remove and entries at the bottom that has something like this - 74.208.10.249 gs.apple.com and replace with 127.0.0.1 gs.apple.com
restart the "workstation" service on the computer.
wait a couple of seconds.
Ping gs.apple.com and make sure 127.0.0.1 replies.
open itunes
start tss server on TU
in itunes hold shift key and click restore
choose the 4.3.3 firmware and of you go.
You should not get any errors.
I have just downgraded now to confirm this method works with the latest version of TU.
Home this helps someone..

is there a way to get a saved shsh blob for 4.3.3? New iPad was updated without saving.
is there a way to get a saved shsh blob for 4.3.3? i upgraded w/o saving
I am on an iPad 1. Follow to the letter but it says my device is not eligible for the requested build. Although I changed the host as described above, when I ping gs.apple.com, I get 17.112.176.11. What am I doing wrong?
worked for me. iPhone 4 blobs saved. updated from 4.3.3 to 4.3.5. downgraded with the terminal method on mac:
In OSX it's located at /private/etc/hosts
The best way to edit the file here is run the following from the terminal app
sudo nano /private/etc/hosts
When it asks you for your password use the same on you use to log into the system.
Scroll to the way bottom using and paste 74.208.105.171 gs.apple.com
Press Control O to save, hit enter, and control X to exit the editor
open iTunes and enter DFU mode, click option/restore and choose official firmware.
**Note, if you get an error the first time repeat the steps above as apples new iTunes will add a # in front of #74.208.105.171 gs.apple.com blocking Saurik’s servers. simply remove the # and control o then control x to save and try again.
Wow!
Thank you very much for this tutorial.
It works like a charm.
I even did not have to use TinyUmbrella.
After downgrading my iPhone 3GS form 4.3.5 to 4.3.3 I jailbreaked it through Jailbreakme.com.
Thanks
I have ipad 1 and was on 4.3.5. I followed excatly the instructions and was able to successfully downgrade to 4.3.3!!!!
I use win XP to do this downgrade and i do not counter any error neither do i have to do any exit recovery.
Thanx a bunch!!
Works well. I got the 1013 error and used the Fixrecovery43 to exit out of recovery loop. Had to put the phone in DFU mode and ran fixrecovery43. Once I got the connect to itunes screen with the emergency slider, all I had to do was connect it to itunes and the phone boot up normally. After that, I just set it up as a new phone, sync, and jailbreak. Done.

succes on downgrading from 4.3.5 to 4.3.3 unthetered.. b4 JB with thetered 4.3.5 then restore to 4.3.3, t q for the hosts file..
Wow this worked great, one that actually works. I accidentally upgraded to 4.3.4, I downgraded and now I have 4.3.3!
will this work for ipad 2. And before you ask no i do not have SHSH blobs. I just bought it, it came with 4.3.5.
Please note i repeat, i do not have SHSH blobs
AWESOME!
What happens if my iPhone 4 is a new one, recently bought. Would it still downgrade because it doesn't work.
Thanks It Worked After ME Trying Another Method for 2 Hours!
hello, sorry but when i want to save this changement in text edit 74.208.105.171 gs.apple.com the file doesn't want register the changment and i can't continue. can you help me ?
I don't know why everyone else is complaining, but with these instructions, I successfully downgraded from 4.3.5 to 4.3.3. Thank you!
That is awesome... Can't thank you enough.
I was having a problem with my Iphone until I did what I read here then it works perfectly...
Meshari
i finished downgrate 4.3.5 to 4.3.3 but i can not exit recovery mode with tinnyumberlla. pls help me
i cant downgraded to 4.3.3 always stuck in the middle of Navigate to the desired firmware to which you want to downgrade to, in this case it can be either iOS 4.3.3, 4.3.2, 4.3.1, 4.3 or 4.2.1. Once you find the required IPSW file, click “Open” and let iTunes do its thing. zzzzz
For everyone who is having a problem with this downgrade, the reason is because apple fixed the patch that they use since on their error message page it explicitly states how this page downgrades. To go around this get redsnow for the tethered jailbreak and instead of checking install cydia, check start into pwned dfu mode. Then it will let you restore to a custom firmware you make from snowbreeze.
This method will never work if no SHSH saved anywhere.
Simply run TinyUmbrella and check Log file after getting shsh.
If it no SHSH for 4.3.3 - no way to downgrade (without tethered jail stuff but it no sense to do this).
followed everything to the t and i got an error 37 :@ plzz help me guys :)
Did everything until a mssg came from iTunes telling my device isnt elligible for restore... Any ideas? Thanks in advance!
hi all,
is it possible to downgrade without the shsh blobs? also tried the modification on the hosts file but no luck, i received a 3194 error. please help.
thanks.
halo? my ipad1 name in tinyumbrella is 1643239412?? and i cant out in recovery mode... what can i do. hacker plzz help me???
please i get an error that it cant be restored because the firmware for my ipad is not compatible
please help
Equipment: IPAD2.
I tried using the same way to downgrade firmware, but I got error 3194. After that, I used tinyumbrella to fix error 3194. And I got error 1601. How can I do next step?
For anyone getting error 1013, this is what I did after a day of punching myself in the face. I'm on an iPhone 4 downgrading from 4.3.5 to 4.3.3. I did have shsh blobs saved in Cydia, you can grab yours using TinyUmbrella if you've jailbroken with the firmware you want to downgrade to.
1. Followed this up until step 5: http://www.redsn0w.us/2011/09/downgrade-ios-5-beta-7-to-ios-435-or.html
2. In place of RecBoot in step 5, I used FixRecovery in the same manner as squarebomb above. You man need the zlib libraries from here: http://forums.ngemu.com/showthread.php?t=106182 to run FixRecovery43.
3. It actually worked, I restored from my latest backup.
-BigHock22
i was unable to downgrade also, then got stuck in recovery. only after i completely removed everything apple and re-installed itunes was i able to just restore...not sure if i'm ready to try downgrading again...it was a long 12 hrs with no phone!!
actual hosts is : 74.208.10.49 gs.apple.com
74.208.105.171 gs.apple.com
get snowbreeze version 2.7

This is very inaccurate and wrong! If it was legit....the creator would be trying to help people out!! Just saying......
As soon as you start TSS server in TU, Itune shuts down and the in the hosts file all 74.xx gets # at the start. Even if you delete #, save and restart itune, it gives you 3194 error. How to resolve this.
What are blobs?
How many people have been successful with this tutorial?

i just bought a new ipad2 ios 5 i have no saved ssh blobs. when is the jailbreak for this going to come out. i need it jailbroken. Help dev team
Will it delete all my apps I have installed on here? I couldn't care less, an unjailbroken phone (in it's current state anyways) is as good as dead right now, tried a supposedly 'untethered' jb from redsn0w and all it did is f*ck my device in the arse and now I can not and I repeat CAN NOT do a tethered fucking boot because it ends in 'Unexpected error (has) occured! with a blank white screen on my 3GS! >:(
Now I'm extremely pissed because not only do I have a broken Cydia, but now I'm afraid if I follow these instructions I'll not only lose all my apps, I'll f*ck my iPhone even worse and lose everything. Well, here goes nothing.
If I lose all my data on there, somebody's gonna get it.
would this steps also work for 5.0 to 4.3.3?
U didnt mentioned SHSH Blobs AT ALL in this guide.
But u said if downgrade without SHSH, use another guide.
This guide is also not using SHSH! right?
can't find anyone who's comment makes sense on how to install this properly without getting any codes?
Not Working, either way... Uhhh. Damn Upgrades!
Is there un update to the hosts since it keeps coming back with this BS error 3194.
FUCKING NO WORK AT ALL
So will these work on iPad2 4.3.5 without shsh blobs? Can someone knowledgeable post a direct answer, all messages and replies here very cluttered, I can't find out who answered who, and for what device. Please use quote when responding so we know to which question response is it.
Gracias! - Swiper the Explorer
that are quite a lots of problemos over here...
I succeeded to get from 4.3.5 to - .3
(after gdDMT 30 min. stuck on some idiote thing)
i didnt even had to use the last step (with tinyumbrella)
i am little bit proud on that =D
