iPhone iOS 4.0 upgrade error – 3002

Note: click here if you’re looking for iOS 5 upgrade error 3002.

While trying to upgrade your iPhone OS from firmware 3.x (probably 3.1.3) to iOS 4.0 you would have received the error: 3002 just like I did. Well the error message said:

The iPhone “nabphone” could not be updated. An unknown error occurred (3002).

Pretty annoying. . .  isn’t it? tried again to upgrade but no use! Ah well… then how to fix this 3002 error while upgrading iPhone firmware from 3.x to 4.0? simple! Read along!

This error occurred when you try to upgrade your iPhone OS firmware to iOS 4.0 (or any other in your case maybe too). Then how to fix this issue? Use the restore instead of upgrade. Yeah! restore and it will do the same thing as it does in upgrade, provided that it will not give this error.

You can download the ipsw for your iPhone model and then restore by shift restore in windows / alt restore in mac

Isn’t it funny that this error comes with the latest 9.2 version of iTunes! I mean oh comeon! you released 9.2 for the purpose of upgrading iOS 4.0 and it gives errors and bugs! dude! do you even check what you release before you make it public? Or maybe they kept this error there intentionally for the user with jailbroken and / or unlocked iPhones? (don’t know if any normal user faced this error in this situation too).

Update: It happens to non jailbroken iPhone / iPod users too. (thanks to Nikhil)

    got the error too. Don’t have my iPod jailbroken..

    • Nabeel

      did you try the “restore” instead of upgrade Nikhil?

      (you can download the ipsw for your iPhone model and then restore by shift restore in windows / alt restore in mac )

      • Nikhil

        Yes I did right bedew reading this article. The only reason that I commented was because you said in the post that you weren’t sure if it only happened to jailbroken users. Thanks!

        • Nabeel

          ohk! :) thanks for updating

  2. K

    You sly summabish..tanks

    • Nabeel

      You’re welcome :)

  3. Elm

    Thanks a lot for the solution, it worked perfectly for my jailbroken 3G.
    I wonder why this bug is not documented on the official Apple site yet…

    • Nabeel

      you’re welcome. I am glad that you were able to fix it.

  4. Vongsar

    NOW I FOUND THE SOLUTION! iF YOU HAVE UPDATE FILE, YOU JUST HOLD SHIFT AND CLICK ON RESTORE AND SELECT THE UPDATE FILE AND IT’S DONE!!!

    • Nabeel

      i mentioned that above in the comments “(you can download the ipsw for your iPhone model and then restore by shift restore in windows / alt restore in mac )”

      adding this to article too.

    Nabel thank you for this useful article…it just sucks i have to wait for my ipod to restore from its backup. Apple fixes something and along with the fix brings other errors. they are so stupid done they do tests on there software’s?

    • Nabeel

      you’re welcome bzza

      no system can be perfect, i am sure they try their best :)

      • bazza**

        Yes, but apple has had this ongoing trouble with all these errors. It seems they almost deliberately do it to have their users constantly upgrading, and with upgrading bringing different things to users attention. for example when i downloaded the 9.2 itunes today because of the 4.0 software i got information about how the brand new iphone is so good yada yada. i believe its their way of advertising in a way. Sorry if this doesn’t make complete sense.

        • Nabeel

          maybe :) and well i think so too

  6. Bee

    it worked, but when restore from backup, it made iphone disconnect and everything lose… :(

    • Nabeel

      why did you restore from backup man?

  7. Darwin

    wow.. thanks for the tip.. I was going crazy dealing with the “Update” thing for like 30 minutes already. 2 thumbs up!!

    • Nabeel

      you’re welcome Darwain

    Help,

    when I tried to update the phone I got error 3002 by using a ipsw file and when I tried using restore again with ipsw file. It says that I am not able to connect the server. I also updated my itunes to 9.2

    Please help….
    Raghav

    • Nabeel

      if it isn’t able to connect to server then probably your internet connection have some error. Can you connect to iTunes store via iTunes?

      • Raghav

        Yes mate, I am able to connect to Itunes stores using itunes… but no luck with restore as it still continues saying that itunes is not able to connect to server temporarly

        • Nabeel

          Probably they updated the files on servers, but as their regional servers update takes some times, that’s why it may be causing delay for you. Just wait for some hours or a day and try again.

          This happened to me last year too.

          • Raghav

            Thanks for your prompt reply… will try that too… I wait for a day or two and try upgrading …

            cheers

          • Nabeel

            you’re welcome, will wait for an update from you. i tried to advice to the best of my knowledge and understanding, i hope it gets fixed by 24 hours.

          • Raghav

            Hey that worked… thanks … But now landed with another new problem.

            My bro has a 3gs iphone which was jailbroken with Blackra1n for 3.1.2. As I had to jailbreak everytime i restart the phone as the iphone would automatically go to restore mode when I restart. I thought of jailbreaking with redsnow 0.9.4. But the iphone instead of jailbreaking went completely dead. Now if i try connecting the iphone to itunes the itunes does not recognize the iphone and neither the apple logo appears on the iphone when I try to start the iphone.

            I have tried everything to get the iphone to start or even show apple logo such as holding the switch off button on top together with the main iphone button. But nothing works need to somehow get to the restore screen on iphone and get the iphone working. Please help mate

    I have a jailbroken iPhone 3G on 3.1.2… I keep getting the same error when I try to update. I have tried to do Alt + Restore and that fails, too. I’m trying to restore this phone, update to 4.0, and then jailbreak + unlock it. Any ideas of why it keeps failing for me? Thanks!

    • Nabeel

      have you been successful to update it?

  13. Kasper Vestberg

    Is this just me or is this “CRAP” OS a fuckton slower than the OS3 ?

    Im using an Iphone 3G … And tbfh its so slow that i dont know if i should throw my iphone out the window or just run it over with my car …

    Downgrades … Is that possible ? Or do you know if they plan on doing something to this OS4 ? :)

    • Nabeel

      if you have your shsh blob saved before upgrading them you can downgrade, otherwise probably no!

  14. Kasper Vestberg

    Well ive tried with diffrent chargers … So it isnt that :)

    And i have no problems with my battery as its almost full at all times (i tend to charge it when its low (takes a few days ^^).

    So its not that :)

    And the OS3 didnt have any problems.

    Also i spoke to other Iphone users and they are ALL having these problems with the new OS4 … Some of em have already changed their iphone to another phone…
    I dont want to as im “in love” with the iphone theme…

    What can i do ?

    • Nabeel
