Jailbreak Tutorial


Ultrasn0w 0.8 tutorial

Run Cydia or Icy and add the repository: repo666.ultrasn0w.com. bear in mind that "0" is the number "zero" and not the letter "o".

    Make a tutorial on how to give the ultrasnow install button…. I would rather call it a comment on ultrasnow ...

  2.   carafe said

    zerocoolspain forgive me for telling you but it is a full-fledged tutorial, it is only a simple process, but if they chew it, better than better.

    By the way Berllin, one question, if we have Jail made and the iPhone released with a version prior to 0.8, is it necessary to do it again with the higher version? And if so, you have to restore to remove the jail and do it again or is it done again?

  3.   daweed said

    And spending time criticizing the work of others I would call it troll.

  4.   berlin said

    carafe
    you do not have to do anything
    what this version has done alone is that it also works for 3Gs

  5.   carafe said

    Ok thanks and keep it up !! Good summers !!

  6.   Georgew said

    Update and it appears to me without service, or three points without signal ......, what can I do to make it work I already restored and do the process and it remains the same, place the sim card in another phone and it's fine, when placing it in the iphone it works normally for a few minutes but then it appears without service ... I already deactivated 3g, I activated again, like airplane mode, and also restarted the phone several times ... help friends I don't know what to do

  7.   Danny said

    The operator can't find me either, and he asks me for my pin ...

  8.   zerocoolspain said

    Daweed: I am not criticizing the work of others, I am simply saying that this cannot be considered a tutorial since the process is so simple that there is only one way to do it.

    Carafa: it is not that they give it to us chewed, it is that it is chewed alone without you biting it ... 😀

  9.   Danny said

    Well with the purplerain I had no problems, at the moment I will only install what they announce that it is compatible with 3GS like the Winterboard (but without issues just in case, little by little). The operator already reads me and I don't need to liberalize it 🙂

  10.   Georgew said

    update and it appears without service, I have iphone 3g, I already installed the redsnow-cydia and the Ultrasn0w repertoire then I turned off and on again ... it appears without service three points without signal ......, what can I do to make it work I have already restored and do the process and continue the same, place the sim card in another phone and that's fine, when placing it in the iphone it works normally for a few minutes but then it appears without service ... I already deactivated 3g, activated again, like airplane mode, and also restarted the phone several times ... help friends I don't know what to do

  11.   berlin said

    Try the purplera1n, to see if it suits you better

  12.   berlin said

    zerocoolspain
    Putting tutorial is because it is an easier way to find it in the search engine if the name is not known, since many use it to search for the word "tutorial"

  13.   zerocoolspain said

    berllin, I give you all the reason in the world, it is a good method if you want to look for it later. I hadn't thought about that ... 😀

  14.   cabricaneco said

    I did something wrong ... but now when I see the iphone I only see an icon that says iTunes, an arrow and a cable as if telling me to connect it and it says slide for emergency ... what should I do to solve this problem

  15.   palrium said

    I also had the same thing happen to me. Cabricaneco installed everything and I got the iTunes icon and a cable with an arrow, please help me or explain what I have to do to solve this problem for faaa: S: S !!!!!

  16.   ojoule said

    Make the jb and use this tutorial and my iphone is 100%

  17.   Simba said

    I have followed everything said by berllin and everything perfect, also with the help of Yordi2000 the truth, now my problem is that many programs and stories that I had before have disappeared, I do not know if I have to download them again and install them or that, like for example the cycoder, sbsettings, bospreffs, etc ...

  18.   Carlos said

    BERLLIN, with persistence and patience I have succeeded! I already have the iPhone 3GS ready to use here, I can now buy my own!
    thank you!

  19.   Evil angel said

    Great! It works perfect, the first time! I have only lost the applications that I installed from Cydia, the ones from the AppStore not. Of course, one of the apps was 'Categories' and the ones I had organized did not appear, I am going to test if installing again I solve the problem.

    Thanks for the tutorial

  20.   me109site said

    Hello Berllin,

    Like other users, Cydia does not allow me to enter the Source repo666.ultrasn0w.com, it tells me that it cannot, which does not allow me to download the little program.
    Thanks in advance.

    I released an iphone 3gs k they brought me from france. but I have problems with the settings where you see your wifi connections, the time etc ... and I installed the cydia sbsetting, but it does not recognize the wifi icon someone knows what is happening or what is the error?

  22.   archi said

    I have a 1st gen i phone released and with version 3.0.1..if I put applications like e buddy, fring or skype ... I don't receive calls or sms, but if I can do them, how is this? Is there any solution?
    From already thank you very much!!

  23.   berlin said

    You have activated push notifications. If you have them deactivated, you activate them and do the test

  24.   joan said

    berllin I plan to buy a (USA) iphone 3g firm 3.0, and when I arrive I think it will be locked, how to unlock it? If I access the functions, I am watching the tutorials to unlock it and you have to do it from the cydia that is supposed to be installed on the iphone.

  25.   Depressor1 said

    I have updated the 3gs to 3.1.2, the release can be done the same as 3.1 ... Please if you can tell me how and what is needed.
    Thanks in advance

  26.   berlin said

    joan

    Hello friends!! I am new to this, but I downloaded the finware and updated my iPhone 3G perfectly well and I got it with the redsnow 0.8 and it opened everything well, the only thing is that it is still blocked for the sim card, I am trying to use the ultrasnow but I cannot download it, I would appreciate if you could help me and explain how to do it please .. From the Dominican Republic !!

  28.   Robert said

    Hello .. Thank you very much berllin I was able to release it with the ultrasno0w, what was happening to me was that I was doing it wrong because I did not know how to search for it in cydia, I do not criticize your work you are a genius, but in that step it should have been a little more detailed the steps, but you are a teacher ... Thank you very much !!

  29.   paco said

    Hello, could someone help me, is that after following all the steps the phone puts me without service, I don't know why
    Thank you

  30.   marten said

    Hello, I also have the same problem, and I am already desperate, I have done the process already 3 times and everything seems ok but in the end it always appears looking for me and in the end without service and I have no way to recognize the sim of any operator ... . please…. What I can do????? thanksssssssssssss

  31.   berlin said

    paco and marta
    How do you want us to help you if you have not given any information.
    What iphone?
    What firmware?
    How have you done the Jailbreak?
    What firmware did you start from?
    What Baseband do you have?

  32.   marten said

    You are absolutely right, sorry ... I have the ipone 3g, firmware 3.0, I installed the cyndia with the resn0w, and then with it from there I released it with one that is 666 ... I do not remember the rest ... excuse me but I'm not very put on these things. . I always get the one I am looking for and then no service ... Thank you for your help

  33.   berlin said

    marten
    I imagine you have installed the ultrasn0w ...
    - Restart the iPhone
    If it doesn't catch:
    - With the iphone on Remove the SIM and put it back
    - Also try another card from a family member or friend
    - Disconnect the 3G and reconnect it
    - Put it in airplane mode and take it off again
    You see trying those things

  34.   marten said

    well ... now I have another problem ... I get the usb cable and the itunes symbol, and entered the link that appears above where you say the steps to follow but when it is restoring it tells me that the card is not valid because it is not the original, is there anything I can do ???? Thanks a lot

  35.   marten said

    okay…. thank you very much for everything

  36.   berlin said

    marten
    I imagine that means that you already have it solved ...

  37.   Javier said

    Hello,
    The same thing happens to me that happened to Marta.
    I have an iPhone 2g (of the first ones) of 8GB I did the jailbreack with blackrain, since with none of the others (snow, ziphone gui, quickpwn) there was a way! Since inadvertently I had updated it with itunes to 3.1.3. I managed to make a down to 3.1.2 and then I did the jailbreack with blackrain (as I have already said) later I have followed the steps; download the ultrasnow and install it ... But the only change is that before it put me without "service" and now it puts me "searching".
    (I have already tried to turn off and on, remove and put the sim card on and off from airplane mode ... but nothing ... there you keep looking!
    Can you think of a solution?
    Thank you so much!!

  38.   Javier said

    Ah! I do not know if it is important, but I bought the phone a long time ago in the United States with an AT and T card. It worked great with the zibris jailbraick until I updated it by itunnes by mistake the other day!
    Thanks again!

  39.   Javier said

    Joeee, I'm clumsy at this time, forgive me ... I forgot to say that I also tried the Boot neuter ... but nothing!
    The only thing that appears is a red dot on the green phone icon! It was the only novelty I got! Because the message is always the same: «Searching»
    I don't put the Baseband on you because I have no idea where to look!
    Thank you and sorry that I have distributed my question in three messages instead of one! : -s

  40.   Javier said

    Thanks Berlin, in the end I already managed to unlock it with one of your old tutorials. The problem was that it did not restart after hitting the bootneuter. Once I rebooted and hit the flash and rebooted, it unlocked me without installing the ultrasn0w.
    So once it's done, I'm sticking with 3.1.2 because the modified ones I don't know why I couldn't get them to admit itunnes without giving me an error.
    Thank you very much again anyway and sorry for the inconvenience.

  41.   Leandro said

    look Berlin I had a problem with my iphone 3g 16GB because by accident I updated the version from iTunes.
    1) I saw an itunes logo with a cable and said to enter a sim, and put the one I had and as it was not valid or something similar. I managed to unlock it to be able to use the functions and all that but it did not raise a signal, I put different chips from companies such as personnel, movistar and nothing does not raise a signal.
    2) the version I have is 3.1.3
    iphone 3g 16gb
    05.12.01 firmware

    1.    Melvin said

      Leandro, how did you manage to unlock it to be able to use the functions?

  42.   berlin said

    Leandro
    With that baseband you can NOT release it

  43.   Leandro said

    and what can I do to make it work?

  44.   berlin said

    Your only possibility would be that you had the Bootloader 05.08:
