Downgrade iOS 5 GM To iOS 4.3.5 On iPhone, iPad, iPod Touch (Guide)

by Jad George on October 5, 2011

Yesterday was a big day starting from the iPhone 4S to the recently released iOS 5 GM for developers. Since iOS 5 GM is installable by everyone, you may have updated to iOS 5 by now. In case you didn’t like the tethered jailbreak, found a few problems on your iOS device or discovered some apps that were not supported, that you desperately needed…  you’re in luck: you can downgrade iOS 5 to iOS 4.3.3, iOS 4.3.5 or older.

Before you downgrade, please remember you can only downgrade your iDevice firmware if, and only if, you have saved your SHSH blobs somewhere safely, hopefully with Saurik’s Cydia server, or locally on your machine.

From now on, I will assume you have saved your blobs on Saurik’s Cydia server.

STEP 1: To start with, you need to make sure you have a copy of iOS 4.3.5 or whatever firmware you need to downgrade for your device which you can find and download from here.

STEP 2: Next, you need to make sure your hosts file is pointing to Saurik’s server, and not Apple’s. If you haven’t done this then please check this guide.

Alternatively, use TinyUmbrella to make iTunes look at Cydia’s Server in the Advanced options.

STEP 3: Now plug in your iOS device, and switch it off, but leave it plugged in.

STEP 4: Put your device into DFU mode, our guide here.

STEP 5: Select your firmware manually to restore to. (Shift on Windows, and option on a Mac)

It says that it will talk to Apple when really, it is talking to the Cydia servers.

Screenshot of the Restore procedureHey presto! Your device should now have downgraded without a hitch…

But, should  your phone should now have an error, such as error 1015, DO NOT PANIC! This is normal and has a quick fix. Just download anduse Recboot to kick it out of recovery mode – check guide here.

In case you’re facing in problems, please let us know in the comments section below.

    awesome, but
    if you have installed the “ipad baseband” you should see the 1015 error, if u didn’t u theres no error you play a clean restor :)

    thanks

  • Adit2351

    Hey I dnt have the shsh saved hw can I do without that???help

  • http://twitter.com/tot_and_ham Jadon William George

    I have seen somewhere while trawling the web a method that does not need SHSH files…

    I am skeptical about this as it is a general rule of thumb that you need SHSH files to downgrade. I will research this and try and find out what i can. The only devices that can downgrade without SHSH files are iPhone 3G, and iPod Touch 2nd Gen or lower

    its ok ,just jailbreak it with redsn0w not other tools (limera1n,greenpois0n..etc) wait till redsn0w jailbreaks it and go to the recboot.exe or tinyumbrella click on “kick out of recovery” this helps ,,i just tried many times ,don’t worry that worked for me

    Hey,

    I’ve tried the iOS 5 GM on my iPhone 4 but when I want to downgrade to 4.3.5, I always get an error “The device couldn’t be restored. There was an unknown error (1).” – I used Tiny Umbrella with saved SHSH from 4.3.5 and manually chose the 4.3.5 firmware from the menu… I also tried to wake the device from recovery mode via Tiny Umbrella but it reboots into recovery mode again afterwards… Hope you can help me because I want to get back to iOS 4.3.5 as certain Apps don’t work on iOS 5 and the graphics performance isn’t as good as with iOS 4 :/

    before I forget tech. details:
    * MacBook Pro (OS X Lion)
    * iTunes 10.5 Beta 9 (10.5b132)
    * iPhone 4 (GSM) 32GB with iOS 5 GM
    * saved SHSH from iOS 4.3.5

    Best regards,
    Christian

  • Oswald

    Hi, I am getting the following error when I try to downgrade from iOS 5 GM (jailbroken) to 4.3.3. Please help.

    The iPhone “iPhone” could not be restored. An unknown error occurred (3194).

  • http://twitter.com/BryanG Bryan Gibson

    my iPhone is really douched…I managed to somehow downgrade from iOS 5 GM to iOS 4.3.5 (using redsnow) but now I can’t update back to iOS 5.  I keep getting errors about the server being busy and when I try to restore with tiny umbrella, I keep getting an error (1).  WTF?  This should be a lot easier…

    UPDATE: oddly enough, I managed to get updated to iOS 5 through the normal route. I suppose there actually was truth to the busy server message…

  • tomi

    I`m in the same boat :| hope somebody can help us :(

  • stickybeak

    Follow Step 2 above procedure.

  • Chris

    Hmmm. I’ve used Tinyumbrella to save my SHSHs, and I’m trying to downgrade my iPhone 3GS with iOS5 back to iOS 4.3.3, but after getting the phone ready for a restore, the phone shows the “connect to iTunes” logo, and iTunes gives an error (20).

  • loyd

    i am getting “this phone can’t be restored. error 20″ too, hope to get a solution…

  • Michael F.

    I have an error 1600. I have tried and tried and tried. I hope to find a solution soon.

  • Chris

    I was able to restore the phone to iOS5 with iTunes 10.5, so at least I’m back to a working state even if it’s not quite what I wanted….

  • विनोद सोबले

    I tried to restore my iPhone 3GS from IOS5-GM to 4.3.3 but all I get is ‘No Service’ in the top left corner & connect to iTunes on my phone. I also see ‘There is no SIM card installed in the iPhone you are attempting to activate’ error in iTunes (10.5)

    PLEASE , PLEASE , PLEASE Help me guys. Is my phone completely broken? I dont mind going back to IOS4.
    Somebody help me (Sobbing)

  • Farr_steven

    You need to do a edit of your host files back to normal. Try taking the phone to another computer and upgrade that way it should fix it if you have any problems you can find me on facebook Stevens Iphone Repair

  • Farr_steven

  • Dhaval M Mistry

    I purchased phone from my friend and I dont have SHSH of iOS 4.3.3. My iphone 4 has iOS 5 (4.11.08 baseband ). How can I downgrade my iphone 4?

  • Sticks191

    i have the same problem, IOS 5 GM with 4.11.08 baseband. no saved shsh or whatever that means. let me know if you found a solution.

  • Spam

    iTunes 10.5 / TinyUmbrella / Trying to downgrade from iOS 5 to a freshly downloaded 4.3.3 ispw. Closest I can get is Error 1600. I do not have my saved SHSH files. I’ve triple checked my host file; tried every combination of checkboxes in TinyUmbrella’s Advanced tab; flush cache repeatedly; rebooted; relaunched apps.

    I do not believe that TinyUmbrella is successfully tricking Apple servers to verify the SHSH.

    I have tried to downgrade from iOS 5 to iOS 4.3.5 on a factory unlocked iPhone 3GS but i always get stuck in recovery mode. When i use fixrecovery43 or fix recovery i get just a blank screen (after the green poison doing its thing)

  • Lml

  • Nade-lou

    I keep getting error 3194. Trying to downgrade from 5.0gm to 4.2.1

  • Hans Accus

    well….the downgrade worked from ios5 baseband 4.11.08 to ios4.3.5, but the baseband does not change still 4.11.08

  • Crco8900

    I believe this does not work with itunes 10.5

  • Djanimelord

    uninstal bonjour apple device support apple software update and itunes and then reinstall itunes and maybe even a reboot that fixed it for me

  • Djanimelord

    to fix error 1600 u have to go into pwned dfu mode.

  • Djanimelord

    try fixrecovery and tinyumbrellas fixrecovery feature. try and use ireb to fix it by going to the 2nd tab on the program (iReb)

  • Matthewericneff

    When I open the hosts file, I copy the 74.208.10.249 and it stays open, do I need to save it and close it? Because it doesn’t let me. The iphone gets about 3 quarters through the restore process then fails and says. “The iPhone “iPhone” could not be restored. An unknown error occurred. (1). I’m running iTunes 10.5, on 10.6.8. What am I doing wrong?

  • http://www.facebook.com/profile.php?id=1336620131 Mike Biondi

    Mine begins to downgrade, the progress bar almost completes then I get an error “for an unknown reason your phone cannot be restored” and it goes into recovery mode. I get it out of recovery mode easily using “fix recovery”, I then put it back into DFU mode and try it all over again, it will not work, tried so many times, it just keeps doing the same thing. I get so far but last second it shits out on me. I really hate Apple for not allowing users to choose what they’d like their phone to run, it’s their way or nothing. Any help in the would be very much appreciated!

  • Matt S.

    I get error 3194 even after upgrading to iTunes 10.5, any ideas?

  • jpc

    Yep – I get the same error as Mike Biondi describes below with “The iPhone “iPhone” could not be restored. An unknown error occurred. (1). I’m trying to downgrade iOS 5 to 4.3.3 – even using iTunes 10.4 – as thought it might be an issue with 10.5 – no luck. Not sure I was really able to downgrade iTunes as I’m simply using a backup version of the iTunes application I recovered from TimeMachine. The error occurs during the “restoring firmware” phase of the restore. After I kick it out of Recovery mode using RedSn0w I’m only able to dial emergency numbers. However I have tried this a number of times. I’m able to Jailbreak the phone, but although the iOS is 4.3.3. the base band is still 04.11.08.

  • SLT

    Hello, when I try to do the following downgrade, such error occurs – “This device isn’t eligible for the requested build” What may be the steps to overcome this problem, since iOS 5 doesn’t work properly on my iPod. :|

  • Bilalh88

    does this work with itunes 10.5?i have the shsh blobs for firmware 4.2.1 4.3.3 and 4.3.5 please help me out when i try to downgrade it gives me an unknown error saying iphone cannot be retored when it is in the restoring firmware phase

  • Saqlainsaleem

    u r right. i have tried so many times but no use in 10.5

  • Katunadzer

    no, you have to have you shs blobs saved, thats the part taht makes it suck! :(

  • Amzi7067

    iphone 4g error 1 while downgrading from ios5 gm to 4.3.5
    please help

  • http://www.facebook.com/YokOshintO Mike Lunge

    not true, apple sign both 4.3.5 and ios 5GM simultaneously for a while, its when they stop signing the older firmware that you have issues

  • http://www.facebook.com/YokOshintO Mike Lunge

    for all those having errors when you’re trying to restore, as stupid as it sounds…try a different usb port. If that doesn’t work, try reverting back without tiny umbrella but make sure your host file isn’t blocking apple servers. (tiny will edit your host file if you’ve used it before)(

    failing that try with tiny umbrella but put a untick the box that says something like “for clean install untick this”

  • Claydees

    same here.

  • Pich

    yeah

  • Unknownly

    Error 1 likewise

  • Lolz550

    me to :s me because of baseband

  • sadman

    same here 5.0 to 4.3.5. error 1. iphone 4. itunes 10.5 :(

  • sadman

    OK, here’s the fix to error 1. You will need latest tinyumbrella and redsn0w 0.9.9b7 mac or win. It worked for me. Full kudos to delusion950 from ModMyI:

    1. Put your iPhone in DFU mode.

    2. Open TinyUmbrella, go to advanced and UNCHECK all except SET HOSTS ON CYDIA ON EXIT 3rd option.

    3. Dont close TU. DO NOT click anything else in TU !

    4. Next Open iTunes and iTunes will tell you that you’re in Recovery that it needs to restore. HOLD SHIFT find(browse) and select 4.3.5 STOCK firmware.

    5. Once iTunes restores your phone you will get an error 1(if you do get error 1, if not then look for your issues else where on modmyi)

    6. No panic yet ! Now open redsn0w 0.9.9b7, Go to EXTRA’s.

    7. Now Select Recovery Fix and follow the rest of the redsnow instructions meaning it will ask you to put your phone in DFU mode while you’re still in recovery. Hold POWER BUTTON and HOME BUTTON it will put you in DFU. Phone will do some cool things we’re used to seeing and it will boot up. You’ll need Simcard to activate the phone once it boots up.

    Now enjoy stock 4.3.5 !
