How to Downgrade Firmware 1.1.3 to 1.1.2

Share:

If you read my post about the latest release of the 1.1.3 upgrade, then most likely you will hear about people who accidentally upgraded to 1.1.3. I’ve received many emails from people asking about how to downgrade from 1.1.3. Please everyone, be extra careful when updating your iPhone when following an unlock guide. Since the 1.1.3 firmware can creep into iTunes, be extra vigilant when unlocking! The secret to AVOIDING the mistake of upgrading your firmware is to…

1. NOT upgrade to 1.1.3 if your iPhone is already unlocked and working. You’ve all heard the saying “if it ain’t broke, don’t fix it.” I think this applies here. If everything is working great, don’t bother upgrading if you just happen to be “bored” one day…it’s not worth the headache if something goes wrong.

2.Β  Pressing SHIFT on your keyboard before you press “Update” or “Restore”. This brings up the option of being able to browse your computer for an older firmware version. My OTB 1.1.2 Jailbreak & Activation guide has been updated to reflect these changes, plus I’ve added a download link for 1.1.2 firmware.

I hate to be the bearer of bad news, but if you made the mistake of upgrading to 1.1.3, you’re hooped for the time being. If your iPhone was previously unlocked as a phone, it will now become a glorified iPod Touch. It’s a matter of time before someone figures out how to unlock the 1.1.3 firmware. But wait! There’s a solution that has been released by Erica of TUAW. She posted a guide on how to downgrade your 1.1.3 firmware to 1.1.2:

1. Get a fairly recent version of iPhuc There are many versions floating around. Make sure yours isn’t too old.

2. Locate your 1.1.1 ipod software bundle. On the Mac, this is in ~/Library/iTunes/(iPhone or iPod) Software Updates.

3. Extract the ipsw file Create a new folder and unzip the 1.1.1 .ipsw file. It is actually a renamed zip archive.

4. Locate the WTF file Inside the unzipped ipsw folder go down to Firmware > dfu and find the file that starts with WTF.

5. Connect your iPod or iPhone to the computer and launch iPhuc Make sure that iPhuc connects to your unit and has a normal prompt (one where you can issue the “ls” command and see the contents of your Media folder). If iTunes starts up, quit it.

6. Enter recovery Type enterrecovery, press return and quit iPhuc. Your unit should go into recovery mode.

7. Relaunch iPhuc. You should now see the recovery mode options. Enter filecopytophone followed by the path to the WTF file and press return. Then Enter cmd go and press return. Quit iPhuc.

8. Launch iTunes. It will complain that it has found an iPod or iPhone in recovery mode. Click OK. Then Option-Click (Mac) or Shift-Click (Windows) the Restore button.

9. Choose the 1.1.1 ipsw file Locate the ipsw file (not the unzipped folder) and select it and start your restore. The screen *should* go white. That’s normal. If all is well and good, your iPhone or iPod touch will downgrade succesfully.

10. Dealing with error 1015 If you run into error 1015, connect your newly restored unit to INdependence or try issuing a cmd fsboot from iPhuc.

Once downloaded, you’ll have to go through all the standard re-activation and jailbreak procedures.

So there you have it. If you upgraded, there is still hope–except you just won’t be able to use your iPhone to make calls. =)

    Great guide, Thanks iPhone Fan πŸ˜‰

    Heres some other wicked news!!!

    1.1.2 OTB UNLOCKED (Hardware)

    First of all, HUGE thanks to TA_Mobile and IMTH for getting us the secpack from 1.1.3 Also, thanks to psp_sully for giving me a 1.1.2 OTB phone to play with. Without them there would be no unlock, and no blog post.
    YOU VERY WELL MAY BRICK YOUR PHONE WITH THIS. Be careful. I have done it sucessfully on two phones, and have never bricked an iPhone in my life.
    So lets get down to business. It is a hardware method to downgrade the bootloader, and I am assuming you are familiar with the old hardware method, so I won’t repeat steps. You need to have a 1.1.2 4.6 phone for this to work. If you upgraded to 1.1.3, have fun waiting for 1.1.4!

    Thoughts to geohot.

    You are a big lamer as always.
    Now many people will brick their phones with “your” method.
    Lol.”your method”.
    You didn’t do ANYTHING.
    You just put together things done by others.
    And thanks you for releasing the secpack.
    We all (devs) had it from 1 month!We didn’t release it because we didn’t want to give apple new weapons and people new ways to brick their phones.
    Do you want a prove ?
    Look at the first message of this blog.
    That number is the md5 of the secpack.
    I posted that on 15th of january 2008 but we had it from a month.
    And by the way, dinopio was the one bringing the attack to get the secpack under gray directions.

    Yikes… This is the last thing I wanna see and read right now, hopefully everything works out… I don’t wanna see the Dev’s go against each other or cause anything to happen with the iPhone. If u know what I mean lol

    Update: We’re now hearing that a software unlock for 1.1.2 / 4.6 iPhones is right around the corner. So don’t crack that case just yet kids.
