How to Downgrade from iOS5 to 4.3.5 or 4.2.10

Recently, has been cracking down on unauthorized iOS5 users. It has been determined that Apple has identified several developer accounts who broke their TOS by selling their slots for a fee to iDevice users who wanted to try out the beta firmware. Apple has begun shutting these developer accounts and if you are one of the people who purchased a UDID slot you will now notice that your device is nothing more than a paper weight.

Please follow the instructions below(Mac/Win) to downgrade from whatever iOS5 beta you are on back to or 4.2.10(CDMA).

Step 1: Download iOS 4.3.5 or iOS 4.2.10

Step 2: Connect your device that is running iOS5 to your computer and turn it off.

Step 3: Put your device into DFU mode by holding down home and power for 10 seconds and then releasing power but continue holding home for another 10 seconds. If you have troubles, check out our DFU mode video tutorial.

Step 4: should detect a device in recovery mode and your screen should be black.

Step 5: Hold down shift(win) or option(mac) and press the "restore" button. Select the 4.3.5 or 4.2.10 firmware file you downloaded in step 1 and the downgrade will initiate. Once it is done, your phone will reboot and you will be back on 4.x firmware.

    Why would you want to do that?

    • JaeM1llz says:

      Use the newest version of iTunes, don’t use the beta.

      • CHRIS says:

        you can’t downgrade your iTunes 10.5 beta to 10.4. iTunes 10.5 creates an iTunes library file that 10.4 can’t read.

        • JaeM1llz says:

          You just completely uninstall iTunes 10.5 and then reinstall 10.4

            Hi Jea,

            I am from India (Bought the Iphone 4 from AT &T ) and I am using Gevey Pro to unlock by iphone4. Yesterday I have upgraded to Os 5 after that my phone is not working.

            1. Do I need to downgrade my Itunes from 10.5 to 10.4? ( just worried that I will loose all my data)
            2. if i restore to 4.3.5 my baseband also be downgraded ?

            Thanks,
            Jim

          • JaeM1llz says:

            Unfortunately by upgrading to iOS5 you upgraded your baseband to one which is not compatible with Gevey and there is no way to downgrade baseband. You will not currently be able to unlock that phone.

    it always says error when i try to downgrade like tht

  3. Kenz says:

    I keep getting the error 1 when I try to downgrade. :\

    Follow these easy steps for downgrade to previous firmware

    1. Uninstall intunes 10.5 beta and reinstall itunes 10.4
    2. Before opening itunes 10.4 open you itunes music folder and rename “itunes library.itl” to itunes library.old
    3. Put your iphone in to recovery mode, plug in to usb and open itunes Dont panic when there is nothing there, itunes creates a new itl file.
    4. Click on iphone in itunes and hit restore
    5. This restores the iphone to ligitimate previous version 4.3.5 in my case
    6. As soon as it completes unplug the iphone from pc and close itunes
    7. Reinstall itunes 10.5 beta
    8. When complete, leave itunes closed and delete newly created itunes library.itl and rename old file back to itunes library.itl

    This allow you to return the phone back to legitimate IPSW and keep your itunes library in tact etc.

    1.To avoid error 1013 i have turned on tinyumbrella and UNCHECKED "Set hosts to cydia on exit" on the adven. tab and 'start tss server'
    2. Turned on the itune with my phone on DFU mode.
    3. Shift+Restore and click on 4.3.5 firmware that i got it ready.
    4. Let itune work.

    ***after this my phone keeps on going to the RECOVERY MODE which does not have slide button on the bottom but just the itune sign with arrow/plug pic.

    I do not know what i have done wrong……….
    please help me out…
    It has been a day already….
    do you know what might have been the problem?????

    • JaeM1llz says:

      If you updated to iOS5 it’s too late. Once your baseband is upgraded, there is no way to downgrade it even if you downgrade your firmware. I would say restore to iOS5 and sell the phone because you’re not going to be able to unlock it.

  6. Oski says:

    FUCK!

    Why did I have to update this morning, why? I was perfectly happy with the jailbreak…

    “you’re not going to be able to unlock it.”

    Does this mean no more jailbreaking, orr..?

    Lost use of my bluetooth stereo headset remote controls with v5. going back to 4.x until its fixed

  8. Igor says:

    I just upgraded to IOS 5 last week, but I want to unlock my iPhone to use in on t-Mobile. What can I ado? Should I downgrade to 4.3.5. version and unlcock it via GEVEY, or there are any other ways to do it? And if I want to downgrade it to 4.3.5 version, how can I do it?
    Thanks a lot

    • JaeM1llz says:

      Once you’ve upgraded to iOS5 your baseband becomes permanently upgraded to a version that is not unlockable. I’m afraid you won’t be able to unlock that phone anymore, at least until Gevey updates their hardware or software to be compatible with the new baseband.

    Guyz.. I was using iPhone 4 with iOS 4.3.5 (bb: 4.10.01) on Vodafone India using Gevey and updated to iOS 5 (bb: 4.11.08) today assuming my that my Gevey would be good to go with the newer firmware. I LOST my Gevey unlock and was unable to use it with my Indian carrier anymore. I came accross this following post and did exactly what they said and was able to downgrade from iOS 5 (bb: 4.11.08) to iOS 4.3.5 (bb: 4.10.01) as apple is STILL SIGNING the old firmware.

    FYI, I never had any SHSH saved with cydia and my iPhone was never jailbroken.

  10. ADARSH says:

    Ok I recently purchased an iPhone 4
    Version 5.0(9A334)
    Model MC318LL
    Firmware 04.11.08

    I jailbroke it and it works perfectly but here’s my problem, I need to unlock it for T-mobile. I did a ton of research and most say i have to unjailbreak it then downgrade it then jailbreak again but i just cant seem to unjailbreak it. I’m lost i dont know what to do. I jailbroke it with redsn0w. Do i have to wait till the people behind cydia are able to unlock it or what? what do i do?

    Hello im wondering if you can help me,
    I am trying to downgrade from ios5 to 4.3.5, I have the SHSH file however I keep getting the error 3194. I have googled it and tried all the solutions I could find however none of them have worked. I have tried having the ‘set hosts to Cydia on exit’ ticked and unticked (both were suggested) but it hasn’t worked. I have also tried putting my device into DFU mode and adding “74.208.105.171 gs.apple.com” onto my hosts file, this hasn’t worked either. How can I downgrade my phone and what am I doing wrong?
