Downgrade from version 2.0 to 1.1.4 (Windows)

If you have updated your iPhone with iTunes by mistake to the newest available version 2.0, you will have an iPhone for decoration. If this has happened to you, no problem. Following the simple and step-by-step tutorial that we show you below, you will be able to have your iPhone fully operational again and without any problem. This tutorial is for Windows. We will publish one for Mac shortly.

  1. We downloaded version 1.1.4 of the iPhone firmware from here and we keep it in an easily accessible place
  2. We have to uninstall iTunes 7.7 if you have already installed it (otherwise go to step 7)
  3. We restart the computer
  4. We downloaded version 7.5 of here
  5. We install it normally
  6. Now, before starting iTunes for the first time, you have to rename the following folder:
  7. C: \ Documents and Settings \ ** your username ** \ My Documents \ My Music \iTunes

    a iTunes Backup

  8. We open iTunes from the desktop shortcut
  9. We put the iPhone in DFU mode with the help of this tutorial
  10. iTunes will notify you that it has found an iPhone in recovery mode, we click OK
  11. Now the iPhone tab will be selected in the iTunes sidebar
  12. We press the Shift button on the keyboard and at the same time we click with the mouse on Restore
  13. We select the firmware that we have downloaded previously in step number 1
  14. We let it finish installing the firmware
  15. At the end you will get an error in iTunes saying that it has not been able to update it, it is normal
  16. Now you use the program of your choice to unlock, jailbreak and unlock the iPhone. WinpwniLiberty, ZiPhone

    Unlocked iPhone: you can use any phone company in the world, without any special fees, as if you bought any other phone. As soon as it is released, all first-generation iPhone owners will update to version 2.0. Each version is better than the last

  2.   anthony said

    which of the last 3 is better?

    Winpwn, iLiberty, ZiPhone ??

    I have only tried the ziphone ...

    which is better?

  3.   Alfred said

    Forgive my ignorance but ...
    What is the advantage of having a "unlocked" iPhone? I mean .. what exactly does that mean? what does a jailbroken iPhone do that one doesn't do with v. 2.0 ??
    I insist, forgive my ignorance, but I just arrived in the iPhone world and I don't know why you consider that it is now overloaded, and what makes it worse than a previous version.
    Someone explain it to me, please?
    Thank you, greetings for everybody

  4.   Alfred said

    Great! thanks Simonx
    the roll then is in buying it but not signing the contract of permanence? Can you operate the phone (to downgrade it) without signing the contract of permanence, or does it arrive totally dead?
    Thank you!

    Hello… I am one of those that my little sister has mistakenly updated my iphone 1.1.4 to 2.0, I was lost and you cannot imagine how I got when I saw the tutorial to go back to version 1.1.4, but she gives me one The thing is that I can't release it, that is, I can't use it and forgive my little wisdom in these parts, the commented programs, neither the zip nor the other, someone can help me. Thanks a lot…

  6.   Furious said

    This is applicable to an iphone 3G ??

  7.   Alvaro said

    Holaaaa… I have done everything but I do not recognize the card, it is not in Spanish either… does anyone know what I can do ???

  8.   davcast said

    this tutorial is to put the firmware back 1.1.4 I want the tutorial to unlock the 2.0

  9.   elmas buscao said

    Goodnight actualidadiphone Just to tell you that your tutorial is wrong, step 15 would have to be deleted because when updating an iPhone to version 2.0 the baseband is also updated to version 04.05.02_G and passing any of the programs that you mention in step 15 could screw up the your readers' iPhone, since when you unlock it you are flashing the baseband and none of these programs are capable of firmware 2.0.

    Greetings from iPhonizados.com

  10.   Alvaro said

    Hello, I am the heavy man from before, I have followed the steps above, and I have gone from having an iPhone 2.0 to 1.1.4 but my vodafone card does not recognize me, also it is in English and the Spanish language does not appear anywhere, I do not What to do, I'm about to take it somewhere, does anyone know how to act ??? I restore it again, load the firmware 2.0 and return it to 1.1.4 ??? I am somewhat desperate ... thank you very much ..

  11.   anthony said

    Alvaro first of all, you have to have the itunes version in 7.5. There they give you the link to download it.

    Then download firmware version 1.1.4

    and there you do the steps that come out there.

    But never update it to version 2.0

    and in the end you apply Zihpne.

  12.   Alvaro said

    Anthony, thank you very much, but I have done it as you tell me and it is mentioned above, that is, I had 2.0 and now I have version 1.1.4, but the problem now is that the vodafone card does not recognize me and I Everything appears in English, we are not in Spanish and I wanted to know what to do ... thank you very much, if you can help me I would appreciate it ...

  13.   Manuel said

    In that case, Elmas looks for how we lower the baseband?

  14.   elmas buscao said

    Manuel ask saimonx, since he also knows what I'm talking about and it is his website, not mine.

    The only thing I do is notify the webmasters of the error that they had, I already have enough with my website, I'm sorry, manuel, don't take it the wrong way.

    ActualidadiPhone Don't take the previous comment the wrong way, it was simply a warning and at no point was it meant to disrespect you.

    regards

  15.   alex said

    I already did all the steps that they say above but it doesn't work, when I use the ziphone it doesn't detect the ihpone ………

  16.   alex said

    when I put the firmware 1.1.4 it gets extrayenfo software and after an error occurred and it could not be restored.
    So I open the ziphone and it does not detect the iphone I do not know if it is doing something wrong or what happens ...

  17.   saimonx said

    If the SIM does not recognize you, it is because you have not used any unlocking software yet.

  18.   Tirso said

    I have followed all the steps to go from 2.0 to 1.1.14 and the truth is that it has been unlocked but the sim does not recognize me, what can I do to make it recognize it ??? thanks a lot.

  19.   elmas buscao said

    the problem is that you have to downgrade the baseband so that the ziphone can work and thus liberalize your iphone's, this tutorial is fine but you can only have an iphone without calling.

    Greetings ActualidadiPhone.

  20.   elmas buscao said

    With the modified Ziphone 2.0, which you can find in some blog about iPhone, I will not make you spread my website here since it is not very professional and then the webmasters of actualidadiphone They would be angry with me.

    regards

  21.   thyrsus said

    I have used the ziphone and it has been unlocked but not the sim, what could be the problem?

  22.   Tirso said

    and how to downgrade the baseband

  23.   ramiroquait said

    I have tried the Ziphone 3.0 and I have not had any problems, Thank you very much for the help.
    I tell you what happened to me: My iPhone crashed and was left in the block without being able to finish booting completely. It happened by uninstalling multiple programs at once.
    As my iPhone was not new and they had already unlocked it, first I downloaded version 1.1.4 to my computer and then I carried out all the steps on this page, it was like to call only in emergencies and then with the Ziphone it came back to life. It was 2 days in which I learned about the processes and the most recommended "Ziphone". At the end there was a direct access on the iPhone screen from the Ziphone page, it is easily removable by pressing and holding the icon and then clicking on the "x". Greetings.

  24.   Tirso said

    Thank you »The mostBuscado» at the end and a little desperate from so many hours giving the computer and trying to unlock it 40E have solved the problem for me, there is a store in bcn that leaves it in perfect condition for that price, I would not pay for it, but in the end I suppose that so many hours of computer and mental health will compensate those 40 E, thank you very much for helping me and I will continue reading these articles if I learn a little more. I hope to have the 3g soon but I am not sure whether to buy the telephone one or wait for it to be sold in a foreign store. what do you advise me ???

  25.   Alvaro said

    Hello everyone ... I am from Tirso's clan, after a lot of trying, getting it halfway, down from 2.0 to 1.1.4, but without getting him to accept my card or this in Spanish, I have made the decision to pony up one store that comes by mobile to my house they release everything perfect and they bring it to me ... but every day I go here to learn, watch and hope that one day I will be one of those who hang something to help others like they have done with me..thank you all and you do not stop writing..thank you very muchsssssssssssssssssssss

  27.   javier torres said

    Hello!! Do not despair Friends! Very soon you will be able to Jailbreak Firmware 2.0 It's just a matter of waiting! I am also very desperate! but today I will wait until they can release the iPhone 2.0
    I have an iPod Touch with jailkbreak 1.1.4 and the app is luxurious, now I can imagine the ones that will come for the iPhone 3G 2.0 (I already have an iPhone 3G hehe)
    Greetings! any questions to unlock the iPhone / iPod Touch 1.1.4 I am at your service reivaj_516@hotmail.com

  28.   Aaron said

    Good actualidadiphone.
    I have a problem following your tutorial since the firmware does not lower to 1.1.4 due to an error (20), does anyone know why? and on top of that, my iphone goes into dfu mode directly, it no longer goes to normal mode….
    merci in advance

  29.   CHRISTIAN said

    SAVE ALL THIS BAD TIME AND USE AGAIN THE FAMOUS CHINESE TURBOSIM OR SIMILAR CARDS OR WHEREVER THEY COME FROM, BET THAT THEY GO UP IN PRICE AS THEY WORK BOTH FOR IPHONE 3G OR THE FIRST GENERATION UPDATED TO 2.0

  30.   Aaron said

    well guys ... I already solved it ... to all those who get the error (20) it is because they have it in restore mode and they have to have it in DFU mode, ok? they are very different…. that is, in recovery mode. Besides, I use itunes 7.6
    Ciao and good luck to those who continue with their problem ...

  31.   joseba said

    when changing from 2.0 to 1.1.4. The install icon has gone away and the phone card does not recognize me

  32.   Hector said

    By mistake I updated from 1.1.4 to 2.0 and it doesn't work. I try to follow the steps they mention but from the outset I run into the problem that I can't install iTunes 7.5, I get a warning that says it can't open because itunes library.itl file has been created with a later version. What I can do????

  33.   George said

    Hello, when trying to install iTunes 7.5 to download firmware 2.0 to 1.1.14, iTunes tells me that it can't because the Itunes Library .itl file has been created in a more recent version.

    What do I do to be able to use Itunes 7.5 as I remove the famous file?

    Saludos y gracias

  34.   George said

    Hello help

    someone knows how to remove the iPod from DFU mode

    regards

    Dear :

    I have an unlocked iphone v1.x (one of the first that came out), since I bought it in the USA but I am using it in my country (Venezuela)

    I want to bring it to v2.0 but I'm afraid it might crash again. Has anyone tried this?

  36.   Rober said

    If you go to see 2.0 you will have the problem that everyone on the list right now has or has had.
    The tutor is going well, but not so well, I am in the famous step of everything ok! as planned and as the tutor says, but now it asks me for the pin gives ok, and my iphone does not make calls. bad business right?
    … What a disgrace to be poor… 😉

  37.   Rober said

    If you click on the name elmasbuscao, author of one of the posts, you will find the solution there.
    I have already achieved it, yes, it is frankly difficult to do it from zero in one day. that's how long it took me, but I think now I could do it a lot faster even in minutes.
    Greetings and good luck

  48.   bakhosm said

    I managed to unlock it today, I don't know if you downgraded the boot, I did that, and also after that I used the ziphone 3.0, to release the bands it could be that ... worse, the safest thing is that you missed the boot downgrade ...

  49.   leandroo said

    I had updated my iphone to 2.0 and I looked and read everything to unlock it and I could not. then I passed it back to 1.1.4 but. after unlocking it doesn't give me a signal? what is the solution??? regards

  50.   bakhosm said

    you have to downgrade the boot

    using the patched zxiphone

    here I leave you the link ...

    http://rapidshare.com/files/119407675/_En__ZiPhone_patched_by_kIREmK_04.05.04_G.zip

    then you run it and give the parameters

    downgrade baseband and debug boot and then use the ziphone 3.0 and give it do it all and voila you might have a signal ...

  51.   leandroo said

    I have a problem, it seems to me only the apple ... and it does not let me do anything as I solve it- .. it does not go to recovery mode ????????? regards

  52.   leandroo said

  53.   bakhosm said

  55.   MARILU said

    We want to thank you infinitely for your clear tutorial, because finally after 3 days of sleepless nights, we were able to unlock the iphone, my husband and I. The fact that you put the accesses to each program that is needed is a huge advantage, since you do not have to look for them elsewhere. Thanks again and greetings from Guadalajara, Jal., Mexico.
