Downgrade 4.3.5 to 4.3.3 on iPhone 4/3GS, iPad, iPod Touch 4G/3G
Few days ago Apple has released iOS 4.3.5, as of now the only jailbreak this available for this iOS is tethered jailbreak, so if you already updated your device to 4.3.5 and would like to have an untethered jailbreak you will need to downgrade your iOS from 4.3.5 to 4.3.3.And because of Apple’s security checks, you can’t just restore the old firmware using iTunes. In this tutorial we will show you how to go around that and downgrade your Apple device; iPhone 4/3GS, iPad, iPod Touch 4G/3G running 4.3.5 to 4.3.3. For iPad 2 3G running 4.3.5 this method will not work because it is not yet possible to downgrade the baseband for this specific version.To get started please follow the steps below:
- Download iOS 4.3.3 for your device:
- iOS 4.3.3 for iPhone 4
- iOS 4.3.3 for iPhone 3GS
- iOS 4.3.3 for iPad
- iOS 4.3.3 for iPod Touch 4G
- iOS 4.3.3 for for iPod Touch 3G
- Connect your device to the computer.
- Put your device in DFU mode by following the steps below:
- Turn Off your device.
- Launch iTunes.
- Press and hold both the power and home buttons for 10 seconds.
- After 10 seconds, release the power button but keep pressing the home button for 10 more seconds. At this point, your screen should be completely black. If you can see the iTunes logo on your device, you’renot in DFU mode, and you need to redo the steps to put your device in DFU again.
- Once your device is in DFU mode follow the steps below:
- For windows users, Right Click on Notepad then click on “Run as Administrator” in the Notepad goto File>Open and navigate to Windows\System32\drivers\etc\ and find a file called “Hosts” (make sure the all files option is selected as shown in the image below)
- For Mac users in the Finder, Click on the Go menu, select Go to Folder and type in /etc/. Now look for a file named hosts. Back it up and open it in TextEdit.
- On either system Windows or Mac, add the following line to the hosts file, then save it. You will need to have administrative privileges on your computer in order to be able to save it:
- 74.208.105.171 gs.apple.com
- Now if you have iTunes Open exit iTunes then Open it Again. Select your device from the sidebar and click on Restore while holding Alt on Mac or Shift key on Windows. Now, browse to select the 4.3.3 firmware you downloaded earlier. iTunes now will downgrade your device to the selected firmware.
- In some cases after iTunes finishes downgrading your device it will put your device in recovery mode and give you an error message. In case you face this issue Click Here to learn how to exit recovery mode.

major issue – iPhone 3gs Old Bootrom, was running on a teathered 4.1 JB – upgraded it to 5.1.1 and was able to but i forgot to install ultra snow and accidentally shut the device down
now its in a never ending look of DFU and cannot even restore it to the custom no BB 5.1.1 ipsw, any thoughts – I’m really looking forward for fix, i tried the above file(mac version) didn’t seem to work. Your thoughts here,
Do you know if your current modem firmware (baseband) is 06.15.00 or not?

hi, could you tell me in case it doenst work, can i restore the original configurations?
thanks!
Yes you can just make sure to backup your device first
Hi, team I’ve jail broken the iphone and the software is 5.1 i mean the last version, so the problem i have every time i power off my iphone every thing will gone and it needs another reboot.
so my question is how to jailbreak full?
What you have a tethered jailbreak which is the only available jailbreak as of now for 5.1. To do a full jailbreak you will need untethered jailbreak which is not available yet, but it should be coming soon.
Can I download the SHSH blob file anywhere? I have another iPhone 4 running 4.3.3, can I save the SHSH blob for that and downgrade my other iPhone 4 running 4.3.5? Thanks!
Hello,
No every SHSH blob is unique for that specific phone and firmware. But that’s smart.
i tried this in my tethered ipod touch 4g 4.3.5 and i got error no. 1093 i guess? so what will i do to downgrade ?
Hello,
This method will only work if you have saved the SHSH blob for your iPod before
Hi,
I have upgraded my ipad1 to 4.3.5 and i want to downgrade to 4.3.3. the only saved shsh blob that I have in cydia are the 4.2.1 and 4.3.5.
Do I have to downgrade to 4.2.1 and then upgrade to 4.3.3, or can I do it directly from 4.3.5 (keeping in mind i only have the 4.2.1 shsh blob).
Hello,
If you only have it saved for 4.2.1 then you will only be able to downgrade to 4.2.1 and then do an untethered jailbreak but you will not be able to upgrade to 4.3.3 since you never save the shsh blob for 4.3.3
Hi Support team, I read the instructions and thought it was all good, but then got majorly confused after reading the comments by others..Please help –
I have an iphone 3gs which was on 4.3.3 the last time. i jailbroke it, had loads of files, and last night my phone decided to die and go in to recovery?now i couldnt do this without having to reset and reinstall everything…that meant going in to new version 4.3.5 – can i downgrade from this using instructions above? and then go back to the untethered jailbreak like last time? sorry but i was really confused after reading everything.
Regards,
Pasha.
Hello,
You will only be able to downgrade if you have saved the SHSH blob for your iPhone before, if not then your stuck for now with the tethered jailbreak.
Hi..support team,just bought an iPad 2 (gsm),trying to downgrade from version 4.3.5 to 4.3.3.as I heard that only 4.3.3can jb without tethering the phone.When try to downgrade ,the error 3194 came out..pls help me
Hello,
You will only be able to downgrade if you have saved the SHSH blob for it before .. otherwise does not matter what you do you will not be able to downgrade. So for now you can do the tethered jailbreak until the new untethered jailbreak is out.

Is there anyway i can break, brick my ipod? and do i need my own back up?
Hello,
There is no way you can break your iPod, worse case senario if something happen you can always restore it through iTunes to the original settings. And yes it is recommended that you back up your iPod before you do anything through iTunes first.
I opened up notepad as adminastrator and found the etc file and switched it to all files but the hosts file will not come up.
Hello,
In your Notepad at the bottom right corner select all files so you can see the hosts file.
hi i did everything said but when i am looking for the file i downloaded after doing the shift+restore thing i cant find it, i thought this would be because it is a zip file, so i tried to extract it and it says its an encrypted file and that i cant do it, like it extracts but now when i am browsing for it i find the folder but there is nothing to click on to downgrade it with
thanks in advance

I have managed to open the hosts file and i have delted the gs.apple.com text but when i try to save a message comes up saying access to C:\windows\system32\drivers\etc\hosts was denied. and i am unable to save the file.
You will need to right click on notepad first and run as administrator.
hi support team i have a iphone 4 that is bricked and i am on 4.3.5 and i cannot get it to come back on what do i need to do please help.
Hello,
Since you’re already on 4.3.5 all you have to do is connect it to iTunes and click on update and iTunes will take care of the rest. In case iTunes is not seeing your iPhone:
1. Make sure its fully charged.
2. Use iREB which will basically put your iPhone in DFU mode which will enable iTunes to see it and then update it.
You can download iReb from here

Hi Support Team,
Ohk, I’ve been through your website and checked out all possible ways to fix things and did all of them.
I accidentally upgraded my iPhone 3GS to 4.3.5 (i can’t remember what it was on before). I’m also trying to unlock it and read that I had to use 4.3.4. I got it unlocked and had cydia on it but it wasn’t reading my sim and everytime the phone rebooted or whatever, it was stuck on the apple sign. Now I read that with 4.3.5 I’d have to jailbreak it everytime it turns off.
So I’ve tried downgrading it to 4.3.4 instead. No luck.
I’m trying to downgrade it now to 4.3.3. Also no luck and I keep getting the same 3194 error that everyone is talking about.
I did the whole hosts thing and that didn’t work either. I did not save a shsh through cydia before so the tinyumbrella thing is not working either. I restared my pc and itunes and i keep getting that same error.
I’m pretty frustrated at this point and have no clue what to do anymore.
Can you please help me?
THank you in advance!
Hello,
Here is where the problem is. You will be able to jailbreak your iPhone with no problem but it will be tethered jailbreak which means that everytime you reboot your iphone you will need to connect it to the computer and the run the jailbreak software again and thats because you have 4.3.5. As far as the unlock you will need to upgrade the baseband to 06.15.00 which requires you to downgrade your firmware to 4.2.1 so i would try the instructions in the link below, but if it did not work for you then that problem would be is that you did not save the SHSH blob before which means until the new jailbreak is out you will only be able to jailbreak it using the 2nd link:
http://unlocker.ws/unlock/unlock-iphone-3gs-any-firmware-any-baseband
http://unlocker.ws/jailbreak-2/jailbreak-4/jailbreak-ios-4-3-5-on-iphone-43gs-ipad-1-ipod-touch-4g3g
Yes it is recommended to run the latest version of iTunes.
where can I find fixrecovery43.exe ???
Hello,
http://thefirmwareumbrella.blogspot.com/
Hi, do I need to have saved SSH blobs in order to downgrade?
Hello,
It should work even with the SSH blobs.
Thanks for the reply.
However, I am curious if this can be done without the SHSH blobs because in my case, I did not save any of the previous firmware’s blobs and updated to 4.3.5 by accident. So, I need to know if I am still able to downgrade it back.
do i need to run latest version of itunes ?
I’m running version: 10.2.1
Thanks so much I am able to restore my Iphone 4 to 4-3-5 using the above solution. Thanks once more and five thumbs up
Glad we could help
