How To: Downgrade From iOS 5 Beta 1, 2 , 3, 4, 5, 6 or 7 To iOS 4.3.5 Without Saved SHSH Blobs

On September 3, 2011, by Jaden

With a lot of people running the iOS 5 beta series firmware, I am sure downgrading back down to the official iOS 4.3.5 firmware has crossed your mind. If this sounds like you, you will be glad to know that the process of downgrading back to the iOS 4.3.5 firmware is extremely simple. It does not involve changing your hosts file or using the application TinyUmbrella and it doesn’t require you to have saved SHSH blobs. This is because the iOS 4.3.5 firmware is the latest official firmware available.

Note: The iOS 4.3.5 firmware can be Jailbroken but it is a tethered Jailbreak. Follow our step-by-step guides in our How To Jailbreak section.

You can follow the straightforward guide below for downgrading your iPhone, iPod Touch or iPad running the iOS 5 Beta 1, iOS 5 Beta 2, iOS 5 Beta 3, iOS 5 Beta 4, iOS 5 Beta 5, iOS 5 Beta 6 or iOS 5 Beta 7 firmware to the iOS 4.3.5 firmware.

Downgrading From iOS 5 Beta 1 – 7 To iOS 4.3.5

Step 1) - The first thing you are going to need to do is ensure you are running the latest development version of iTunes on your computer (which will be iTunes 10.5 beta 7). You can download iTunes 10.5 beta 7 for Windows and Mac OS X from the Apple Dev Center.

Step 2) – Once you have ensured you are running the latest version of iTunes on your computer you will need to make sure you have access to the iOS 4.3.5 firmware. If you need to download this firmware file you can go to the iJailbreak Downloads Section.

Step 3) – Now comes the hardest part; You must put your iPhone, iPod Touch or iPad into DFU mode. This is done by doing the following:

  • Turn your iPhone, iPod Touch or iPad off.
  • Hold the Power and Home Button for exactly 10 seconds.
  • Once you Hold the Power and Home Button for 10 seconds release the Power Button and continue holding the Home Button for up to 30 seconds

If you enter DFU mode correctly iTunes will open telling you that that you must restore your iPhone, iPod Touch or iPad.

Step 4) - With iTunes open press Shift+Restore (Windows) or Option+Restore (Mac) and select the iOS 4.3.5 firmware file. Upon doing this your iPhone, iPod Touch or iPad will begin restoring itself to the iOS 4.3.5 firmware without any problems as the iOS 4.3.5 firmware is the latest official firmware.

    i have the latest version of iTunes, and i downloaded 4.3.5 so i could get it on my iPod when i click opt-restore, but i keep getting error 21 or 1604. what do i do?

  • Chris

    Will my iPhone show up in iTunes beta 7 after restoring to ios4?
    and will I be able to restore from the backup that I did while still on iOS5 beta 7?

  • http://www.facebook.com/DannyNewman89 Daniel Newman

  • Belal Miah

    works a treat. :)

  • Sourcecodepoet

    I can downgrade to iOS 4.2.1 (last version installed on my 3GS before the update to iOS5B7), but it just won’t go to 4.3.5.

  • http://www.facebook.com/jasper.lynn Jasper Lynn

    yes it will, just tried it on mine!

  • Bahadir

    Yes me too!

    Doesn’t work this way.

  • http://www.facebook.com/PreeTmac Preet Singh

    i m also

  • http://www.facebook.com/luistiagofelix Luis Tiago Felix

    did you used the saved shah to downgrade to 4.2.1? thanks

  • Stephan

    i did it as described, but itunes crashed while restoring 4.3.5

    only way to get my 3gs working is installing latest itunes 10.4 and downgrading to 4.3.3, then using fixrecovery to get out of recovery loop after error 1015 …

    any recommendations?

  • Sukthedick

    your iphone will show up in iTunes beta 7, but you can’t use the backup from iOS 5 because of the way iOS 5 backups work.

  • Abudabest

    keep getting error 1

  • Techasianreview

    it didnt work!

  • Sourceocdepoet

    Yes, for the downgrade to 4.2.1 I used saved ones, but for 4.3.5 I did not have, thought they were not neccesary.

  • Ryan_corrella

  • Theking_world2009

    without any hopless programs

  • Theking_world2009

    the apple still support 4.3.5

  • Sar

    I am also trying to downgrade, and I get an error, and than my phone will just reboot and I still have iOS 5. Does iTunes have to be 10.5 beta 7 for this to work for sure

  • Guest

    It works fine until the end of the restore, when it ‘verifies’ with Apple. Then it says I’ not authorized for 4.3.5, and quits! It won’t do it without being connected to the internet either! I have ITunes 10.5, and and Ipad 2 16G WiFi.

  • Vitorffarage

    My iTunes, as soon as the iPhone is on DFU mode, pops up a screen saying that the update server could not be contacted and telling me to check my internet connection… I tried it with my firewall off and still had the same problem. Does anyone know how to solve this? I have the latest version of the iTunes, but when i click “check for update” it pops up the same window saying it cannot reach the server… =/

  • http://twitter.com/LabeLmeAgod L0s

    no Apple A5 processors are not supported yet

  • http://twitter.com/LabeLmeAgod L0s

    If you dont have the Blobs saved, you cant… only ifaith will help if you are already on 4.3.5

  • http://twitter.com/LabeLmeAgod L0s

    The downgrade does not work anymore as 5.0.1 is finalized at this time… Apple is only signing 5.0.1 at the time and 5.1 next… if tinyumbrella doesnt have your SHSH saved… you CANNOT DOWNGRADE

  • Anonymous

    I wish I had known that before I tried this! Now my phone is all messed up and I can’t downgrade or do anything. Why didn’t you delete this tutorial if it no longer works????

  • Rahul

    also i got problem error 3194

  • Kowuaou11

    No wonder why) It’s because blimey apple isnt signing old ios anymore.

  • Freakout

    IT DOESN’T WORK!!! Apple is being a douche and isn’t allowing you

  • Anonymous

    iOS 5 is a piece of shit. We need a fix for downgrading ASAP.
