    And for those of us who already have tethered jailbreak, this tutorial doesn't help us, right? Will they release some kind of patch for us the same as they released for Mac?

    1.    gnzl said

      IF YOU HAVE JAILBREAK TETHERED YOU CAN FOLLOW THE TUTORIAL.
      .
      IF YOU HAVE JAILBREAK UNTETHERED MONTE NO, YOU HAVE TO RESTORE.

    Has anyone who had the tethered with RedSnow tried it on an iPhone 4?

  3.   jlripollez said

    Ok, it's the first jailbreak I'm going to do so sorry if I ask the obvious.

    The process would be:
    1- iPhone backup.
    2- Clean restoration (I understand that this is to give it to restore in iTunes and that's it, right?)
    3- Jailbreak
    4- Restore everything with the backup.

    Some type of data is lost or you recover everything, that is, personal data, settings, games, game progress ...

    Thank you

    1.    gnzl said

      Correct jlRipollez

  4.   yefry said

    Tested on iPod touch 3G with tethered jailbreak with redsnow. Works well and fast

  5.   yefry said

    jlRipollez. You lose absolutely nothing, the only thing you lose are the installed cydia applications, but since it is your first jailbreak, you don't lose anything.

  6.   the route said

    Thanks Gnzl!
    So I understand that if you have a tethered jailbreak, you just have to launch the greenpoison, enter the iPhone in DFU mode and when it restarts it is already untethered, right? Everything about the Loader program and then we save it ...
    Thank you very much in advance

  7.   Rafael said

    It is perfect for the ipad and the iphone 4. Now the only con is the logo, does anyone know how to get the skull and crossbones?
    Thanks for the jailbreak yankees !!!

    1.    gnzl said

      EFFECTIVELY THE ROUTE
      .
      RAFAEL, CAN'T BE REMOVED (IT'S THE HACKERS 'BRAND)

  8.   rafael said

    And well I can live with that hahahaha
    Up and hitting the switchboard makes you go to safe mode in 4.2.1 with the jailbreak not installing !!!

  9.   napster12 said

    but to do all this the iphone has to be in the original 4.2 or can it be done from 4.1?

  10.   napster12 said

    Will I lose the apps when restoring if I don't have them on iTunes?

  11.   Francisco said

    My screen is blank ... now what?

  12.   TioVinagar said

    Gnzl, once this is done I will have to reinstall the Cydia Apps that I use, right? Is there a way to make Backup so as not to waste a lot of time with it? Thank you!

  13.   jor said

    I have an iPhone 4 jailbroken me and I install the iLoader lowers cydia and dps open Cydia and it says starting and crash and reboots! And nothing ! It has iOS 4.2.1 and use for windows! Does it happen to someone?

  14.   Galician10 said

    It worked perfect on iphone 3gs with redsnow.

  15.   Alexander said

    Hello and why can't you jail, if you need to release?

  16.   JoseDH said

    I did the jailbreak already having the redsn0w tethered and the iLoader did not come out but directly as I already had Cydia it works perfectly for me. 😀

  17.   Alfonso said

    Well, if you can't remove the skull, I'll continue with my 4.1 xq, I don't like that nonsense. I did the jail also with GreenPoison to my 4.1 and even that strange hairline that appeared when doing the jail disappeared when you started the phone with 4.0.1, which is appreciated because it seems that it has nothing done. Those marks of… "I HAVE DONE IT !!!" they get on my nerves. If someone discovers the method to be able to put the normal Apple logo that says so, then if I restore to 4.2 and do the jail, but for now, no.

  18.   David said

    Hello, I am going to perform the jalibreak but I am afraid of losing the previously installed applications, which there are several that I have purchased through the app.
    I have to restore so I will lose the applications, right?
    I have already done the backup before the jali.
    So, I restore, perform the jali, and then load the backup ???? so I won't lose it right?

    I am a newbie therefore…. Hahaha

    Thank you.

  19.   iphoneru said

    A doubt, I have put myself to it, and when doing the restoration it automatically starts to download the software update of the device, it will not be the update 4.3, right? I have disconnected the iPhone and canceled the download, how can I restore the iPhone without downloading an update? I want it to continue having 4.2.1 hehe

  20.   nn said

    Made on Ipod 3 without problems

  21.   Aitor Mint said

    Good, ignore my ignorance and see if someone helps me, I have an iPhone 4 with version 4.2.1 and it has never been Jail, my doubt is that if ever for warranty or other issues I would like to leave it factory, I have heard that I would have to do a »downgrade» but I think that for that I would have to save the SHSH of the original firm that will always be earlier than Jail's. I'm sorry for the rant and if someone helps me or clarifies something, thank you!

  22.   alberdeparla said

    Haber, for those of you who ask if the app is lost or not when doing the jailbreak ... The mobile is lost because obviously we are restoring it and leaving it clean with nothing. But once the jailbreak is done, it is re-synchronized with iTunes to pass contacts, agendas…. You also synchronize it so that it sends the apps to the mobile and you will have them again on the mobile ...
    If any app does not appear on the mobile, you must install AppSync from Cydia, OpenSSH and other programs to be able to put the apps on the mobile.

    For Iphoneru, when it tells you to download a new version in iTunes, it should tell you which version is going to be downloaded in the notice ... I don't know if it will still be 4.2.1 or they will have updated to 4.3. If they have updated to 4.3, download firmware 4.2.1 from getios.com and restore it with iTunes, looking for the file on your computer (Shift and without releasing the restore key and looking for where you have saved the file). Once the 4.2.1 firmware is installed, you follow the usual steps of jailbreak unthetered.

    All the best

  23.   David said

    Thanks Alberdeparla.

  24.   Ser83 said

    Made in Iphone 3GS with new and perfect boot! Thanks a lot.

  25.   Ernesto said

    Has anyone tried it on the iPod Touch 2g MC, the so-called "cursed jailbreak model"? XD because I remember that in the jailbreak for 4.1 originally it did not work until they released rc4

  26.   ramdall said

    Guys I need help. When restoring I got an error (1013). Can somebody help me??

  27.   Climax said

    I have followed the tutorial on my iphone 3gs tethered (redsnow) and at the time of restart it is left with a black screen, then the charging circle appears. Pressing the power + home it restarts again but when the greenpoison logo appears, the charging circle appears and it gets caught again. Ask if someone has a solution because right now I have a useless iPhone ...

  28.   elsilva said

    If Ernesto works perfectly on iPod touch 4.1 2g mc

  29.   elsilva said

  30.   alberdeparla said

    Climax, try to put the iphone back in DFU mode and try to jailbreak again if it works

  31.   Rafinha said

    Does anyone know how to recover the original Apple logo when starting the iPhone? It is that I would like to be able to remove the skull of greenpois0n. All the best!

  32.   alberdeparla said

    You can't with this Rafinha jailbreak

  33.   jlripollez said

    Jailbreak done perfectly. I'll see if it has bugs.

    Panic moment after restoring the backup that did not install anything I had, but after a second restoration everything was perfect.

  34.   jlripollez said

    Hey, in Cydia it says "This device has a pending TSS request". Is there something i need to do?

    I have followed all the steps and apparently it has been jailbroken but the loader icon does not appear. Please help

  59.   Mirko said

    If you can remove that logo and even put another personalized one, I read it on a page of this type but I don't remember how it was, it was something like with the ifile enter a folder called bin and delete what file, or the file is called bin, inform you about this

  60.   vine_g123 said

    Is there no one who happens to me?

  61.   Miguel said

    Hello, to make the restoration clean, how is it done?

  65.   The Route said

    Hello GNZL

    I have already done the jailbreak starting from tethered and everything is correct, although I got the warning that I could not find four folders. The only problem I have is that when I turn on the iphone it always turns on THE SAFE MODE. I give Restart and solved but would you know why it could be? Is it related to the folders?

    THANK YOU SO MUCH

  66.   robertofelce said

    Shouldn't SHSH be saved first before jailbreaking?

    What if i have never saved SHSHs with tinyumbrella and jailbreak for the first time with green poison?

  67.   vine_g123 said

    Dad, what do you have?

  68.   David said

    I have an iphone 4 ios 4.2.1 with the old tethered jalibreak, I have directly left it as it is and I have started doing the greenposion jalibreak, I follow all the steps, (by the way, super simple !!) it restarts and… wala! the mobile as it had everything as before ... my installous ... my cydia ..., etc ... and the loader that you mention nothing at all, but I have to tell you something ... I DO NOT WORRY !! since I can already turn on my iphone 4 without the computer, I already have it untethered! hehehehe, thanks for the contribution guys !! already greenposion !! XD

  69.   Gonzalo said

  70.   ivan said

    hello everyone when i jailbreak my ipad no problem but then yes
    I have a problem that the springboard is transformed as if it were an iphone, everything changes places and stripes appear everywhere
    how do I solve it?

  71.   Screws said

    Everything Perfect, I had 4.2.1 out of the box and I have already made the JailBreak! Thanks a lot!!!

    Now, what is it? Could you put a guide with the first steps in cidia for those of us who are new to this, which are repos and stuff!

  72.   ivan said

    Please I ask for a lot of help I explain my problem in more detail
    I have an ipad 64gb + 3G with ios 4.2.1
    Today I jailbroken it and everything is fine but later without knowing when I unlock the ipad, everything appears to me as if an iPhone was seen on the screen, the icons get smaller, everything changes places, the applications work as if they were an iPhone, one thing very rare I ask everyone for a lot of help!
    I think it could be from the greenpoison that everything is not perfect and there is some mistake!

  73.   Pelayo said

    Hello everyone. Gnzl (or anyone who can answer me) a question, I have not done the jail yet, do you know if Skype works with jail? I say this because other times that I have jailbroken, Skype did not work because it detected that it had been modified.

    Thanks a lot !!! 🙂

  77.   Bill said

    Friends I tell you that for those who have made the JB with redsn0w and firm 4.2.1, they DO NOT need to restore or update anything, just do the JB ON TOP OF THE ONE AND THEY WILL ALREADY BE UNTETHED… .. I did it on iphone 3gs with new boot and with Baseband of the ipad and it was perfect, I recommend it….

  82.   comber said

    Let's see that I clarify, then, with an iPhone 4 from France released by IMEI and firm 4.2.1 without any type of jail or anything, is doing this enough? Doesn't it have to be connected to the internet either? I say this because here in France I do not have a data connection, and where I am there is no Wi-Fi… and in all the images of the tutor the Wi-Fi icon appears as if it were used or something.
    Sorry if my questions seem silly, but this is what being an iOS newbie is: /

  83.   Javisteam said

    Jail done and Cydia installed, only two issues:

    1st cydia is slow as the bad man's horse, I suppose that in the next few days it will go faster, I think it will be due to saturation.

    2nd I put to restore the backup copy that I had made with iTunes and it takes about 20 minutes !!! it has never taken so long.

    Any ideas ?, Thanks in advance and greetings to all.

  84.   Jasvisteam said

    COMBER #
    If I'm not mistaken, you need a Wi-Fi connection to download cydia, otherwise it will give you an error.

  85.   comber said

    Come on, I'm going to have to go to a cafeteria with wifi or to the university to do the jail… jop

  86.   rurre said

    I do not know if it only happens to me, but 4.2.1 is much worse than 4.1 on a 3GS.

  87.   Shawn said

    If you need wifi to download cydia ... (Javisteam) that is what I say, cydia had never seen it so slow, it is amazing, I hope it is due to saturation.

  88.   Jesus said

    It works perfectly.

    Hello, I've done the jailbreak with the greenp0ison having the redsn0w tethered jailbreak and everything is fine, but the uploader has not appeared, I already had the cidya installed and everything. Am I missing something?

    I HAVE AN IPHONE 4G BB 02.10.04 PURCHASED IN THE USA IN MY COUNTRY IT DOES NOT WORK WITH ANY OPERATOR WITH THIS SOFTWARE CAN IT BE RELEASED TO BE ABLE TO USE IT?

  91.   For July said

    No, it only serves to jailbreak. To release it you need the tiny umbrella. On the page there is a post that explains how to do it

  92.   comber said

    To all this ... those released by IMEI do not lose the release, right? It would be logical, but let's see if I'm going to screw it up ...

  93.   Rafinha said

    One question, it happens to someone else that when he is in google, using the 3G mobile phone, and performs a search, he cannot access the search links and I get the message “Safari cannot download this file”. With wifi if everything is going well, but with 3G I get this message.

  94.   Luis said

    This is used to jailbreak the firm 3.1.3 ??

  95.   cheston said

    To those of us who had the redsnow tethered, the uploader icon does not appear, simply because I imagine that having the cidya you no longer need it, a colleague is doing it and I hope the loader comes out, since he has it virgin When I know something, I'll tell you about it, but after what I've seen, it comes out.

  96.   fali94 said

    It works perfect! i have an ipod touch 4g with version 4.2.1 and jailbreak untethered by redsnow. I have jailbroken it with the greenpoison and it works perfectly. what does not appear is the loader, but I suppose it will be because I already had a tethered jailbreak done.
    PS: how nice it is to see how you can turn off the ipod without fear haha ​​=)

  97.   Fran said

    It was working the first time on an iPhone 4 without first being tethered. I mean factory. Salu2

  98.   lol said

    LOL

  99.   George said

    It works fast and perfect, I coincide with Fali94 and Cheston .. I had echoed the tethered and the loader did not come out .. Many thanks for the tutorial

  100.   xusi said

    The same thing happens to me that rafinha, google from safari with the iphone 4 does not work for me, I can not access the links that come out there, on the other hand with wifi yes, I have vodafone, I don't know if it will be the fault of the operator or the mobile … If someone knows something I would appreciate if you could give some information! All the best!

    Let's see if the fucking pesaos who do not deign to read understand this ...
    THE JAILBREAK DOES NOT UNLOCK THE PHONE. TO RELEASE IT YOU NEED TO DO JAILBREAK AND THEN, DEPENDING ON YOUR BASEBAND, INSTALL OR NOT ULTRASNOW.

    works perfect and fast for an iphone 4 bought two weeks ago with 4.2.1 !!!

    thank you very much!

    Hi Hi, I just did the process with a 2GB 16G ipod and everything is perfect, I delete the loader but CYDIA does not open for me .. it tells me initializing files and the second it returns to the main screen of the ipod, what can happen? have I done something wrong? Greetings and I await your response.

  113.   dlcmdrx said

    And the release?

  114.   Miguel said

    I have a question, I have the jail with 4.1, if I update to 4.2.1 I will lose everything obtained with the jail, if I do the jail in 4.2.1 and restore from a backup made while I had the jail in the 4.1, would I have everything obtained with the jail in 4.1 again?

  115.   shoemaker-ol said

    The same thing happens to me as GALI, with the ipod 2g mc that jail has but does not open, cydia locks up and does springboard.
    it is rare since the springboard is only one time: HELP!

  116.   rurre said

    Miguel, the apps do, but everything in cydia will have to be done again. There was an app in cydia that made a backup (aptbackup) which I don't know if it works for this iOS.

  117.   tonymoon said

    I had thetered and now with the unthetered I do not know why but cydia does not install anything, I do not know if it will open it to someone else, I will have to restore and do the process with a clean iPhone ... by the way see if people already find out about one instead of k these tools do not release the terminal

  118.   Aaron @ said

    It works fine, My iPhone 4 version 4.2.1 from the factory, I apply the jai directly without deleting
    Nothing. Thanks for everything you do a great job

    I have a 4 gb iphone 32 with firmware 4.2.1 and baseband 03.10.01 is not yet unlocked read above that if we need to unlock it, do not follow the tutorial that you advise me to do ???
    wait a lot of time since the jail unthetered comes out and now I don't know what to do ??? When will the ultrasn0w come out, or do you recommend me ???

    regards
    THANK YOU

  120.   Eduardo said

    I have a problem. Everything is perfect for me, but when I have the jailbreak, the coverage of being at full throttle down to one line and sometimes none at all. Why is that? It is an iphone 4 with 4.2.1 from vodafone. All the best.

  121.   kephren said

    To Cristian, I have the same iPhone 3G as you, I did the process as explained but the countdown did not pass, it stayed there and no longer turned on my iPhone, I repaired it by leaving it connected to the pc and iTunes almost restored it By myself, as I had a backup I stayed the same as before doing it, but in the end it did not work for my 3g 4.2.1 I better wait until another version of the jailbreack comes out

  122.   king jor said

    awesome thank you so much for the tutorial !!! I was sick of having to restart my iPhone with the PC thank you thank you very much

    Incredible how well the jailbreak with greenposi0n is going. I have not had a bug so far. (you don't have to say it too harshly)

  125.   spartan mx said

    Hello everyone.

    I have a doubt:

    When doing the jailbreak to my iphone4 (bought in the USA) everything works perfect.
    Only now when I check the version info I see IOS 4.2.1 (9Z999)
    Someone knows something about it?
    Does this happen to anyone else?

    regards

  126.   Homerisho said

    Hello anyone know if Greepois0n Hacktiva?

  127.   berick said

    I do not understand!!!
    Everyone said that iOS 4.2.1 was the "WORST" system, now it turns out that it is the best, it even says that it is faster.
    I'm going to test it on my 3GS 4.1, see how it works.
    regards

    If you have to restore the iPhone as new ... and then jailbreak, how do you restore the data later ???

  129.   Marclona said

    Good morning

    First of all, I would like to thank Gnzl for the tutorial, for the speed in making it and making it available to the followers of the web.

    Working perfect on several iphone 4.

    Thank you

  130.   Andoni said

    Thank you,
    works perfect with iphone 4 firmware 4.2.1 "virgin" with loader, cydia and others.
    Salu2

  131.   muscles said

    A question

    Can it be done without restoring to factory? I already have 4.2.1, could I do it directly with my iphone? without restoring now to new iphone?

    IF I have to restore ... how can I make a copy of my contacts? because when restoring to a new iphone, pass the jail to it .. then I can't restore a backup copy and it doesn't give me the contacts?

  132.   Eduardo said

    Can someone tell me why I lose coverage when jailbrokening ??? It is an iPhone 4 with 4.2.1 from vodafone.

  133.   frankiii said

    Tested on two ipod touch 4g with redsnow tethered and without restoring and EVERYTHING PERFECT !!! Very fast and effective! 0 problems

  134.   Marclona said

    Good kaski

    I have done it without doing the restoration first and I have not had any problems.

    In any case, it is always advisable to first make a backup copy of the device before making any changes and thus you can always restore the backup in case of problems or change of terminal.

  135.   muscles said

    I always have a copy ... what I said is if there was a problem in not doing it with factory restored ...

    Thanks Marclona

  136.   taru said

    perfect, it has worked for me the first time ... I have a question, I have made a restoration so that it was empty when doing jb, if I recover a backup now, the jb is not deleted, right ??? thanksssss!

  137.   melon kid said

    Perfect on my iPhone4: no problem in the process and, at the moment, no rare side effects detected.

  138.   mantsan said

    Thanks, Gnzl. From what I read:
    1.- It works for 3GS with new boot as well.
    2.- even if you don't have the shsh saved (I had JB from 3.1.3, but later I lost it; and I've been with 4.1.2 without JB for a while).
    I understand that this JB is practically universal (contrary to rumors that it could not be used for the 3gs newboot, or for those who did not have the shsh saved).
    CAN YOU CONFIRM ME? THANKS A LOT.

  139.   Pope said

    After doing the jailbreaking it gets stuck when it resets.
    It goes black and does not get to load anything.
    I wait a good while, I reset it and it returns to the normal state but without having done anything.
    Some idea.

    change a 3 g for a 3gs the day before the windows version came out
    and it was a 4.2.1 with 06.15.00 that came standard and above with the new iboot
    I have done it this minute and it seemed that it was hanging with the apple and the usb cable for a long time, in the end the skull and the loader came out, I load the cydia and well, I pass the ultrasnow and it liberalizes it, but the ipas that I had , I do not synchronize them well I get unknown error (0xE8008001) Can someone help me to know what I have done wrong ???????????????

  146.   Ricky said

    You are the bomb. Perfect manual. Many thanks.

    It was perfect on the second try. In the first one it gave me a "jailbreak failed", I don't know if because I closed the itunes while I was jailbreaking ...

    In case it helps someone: I had the Vodafone 4.2.1 factory and I have jailbroken without previously restoring.

    What was said. Many thanks for your work.

    A greeting.

  155.   Enrique said

    I already have it done, without restoring. A question may be silly, it is my first jailbreak, and I have lost the icons of contacts, apple store and some more that I do not detect but the gap is missing

    It is normal? Can they be recovered?

    Forgive if the question is very silly

    Hello, I wanted to know if the fact that the mobile is free (bought in the apple store go) affects the jailbreak.

  160.   Abel said

    I do on an ipod 2g, iphone 3gs and an ipad, just a curious detail on the ipad I do not get the gp skull but in the rest yes, but hey has the first one without errors or anything at the moment I have not seen any bug like this First the only thing I miss the 3gs the cydiy app is downloaded and then they tell me that there is an update that are the same as download but once you restart the springboard everything returns to normal,
    now the only thing missing is the long-awaited musclenerd unlock for the following basebands.
    by the way, the last baseband that is uploaded in 4.2.1 is 05.15.04 and that nobody commented on it, it was uploaded to me from 03.10.01 and the iphone 4 from 02.10.04. So now it will be another different baseband to unlock, right?
    In short, wait, now we will see if with the arrival of 4.3 there will be a new surprise for next week.
    thanks for the tuto.

I don't understand what may be happening ... can someone help me?

  172.   alejandra said

    When the screen goes black or in recovery, I put it in redsn0w, just boot tethered right now, and it returns to the jb tethered. Hopefully it will serve those who are left with that problem by not being able to do the jb.
    I can't do it either, I have a 3gs 4.2.1, jb tethered with redsn0w, and I have followed all the steps, I have restored the cel, etc, but when trying to do the jb with greenpois0n, in the middle of the process I get a warning that says greenpois0n.exe has stopped working error. And the program closes. And I have the cel in dfu and I have to do redsn0w again.
    It seems that I have to stay tethered no more

    Well I have discovered a BUG IN THE GREENPOISON JAILBREAK of 4.2.1 on both the iPhone 4 and the ipod4 and it is that the Google Safari does not work well! And it is tested on several iPhone 4s and all the same!
    The problem is when you visualize the Google in classic version NOT mobile edition and you put a word in the search engine and hit the SEARCH WITH GOOGLE button because it does not work! And if you give GO TO HAVE LUCK instead of going to the page directly, it does a search in Google but in mobile edition and you give classic to see the search and it does not change!

    This is proven in many iPhone how strange it is that no news of the failure was found on the internet!

    Hi, I jailbroken iPhone 4.2.1 4 with greenpois0n, I'm new to this, it is said that it will be released soon
    the update version of IOS 4.3 my concern is, what will happen when iTunes asks me to update
    the iphone 4 to version 4.3.
    since I have cydia apps.

    what should I do?
    to update ios to 4.3, without losing my cydia apps and purchased apps stores; like
    configurations and customizations that I have made to the iphone.

    I remind you that I am new to this and it is my first jailbreak.
    regards…

  190.   Dany Redward said

    Result to the second attempt, the first time the itouch (4g) was left blank, it was only necessary to apply reset (press the power and home button at the same time until the apple appears) and restart the jailbreak again. Cydia installed very easily. Do not forget to install the appsync 4+ if you use hackulos repository. Greetings and thanks.

  191.   molly said

    I try to jailbreak but I can't put in dfu, I get following the steps, try again. I pulse 2 sec power then I pulse power and home for 10 sec and finally I release power and 15 sec home I do not know what I am doing wrong

    Has it been satisfactory with the iphone 4 4.2.1? is it independent of the firmware of the modem ??

    Thank you

  222.   Capitan said

    Hello people! I make a query, I have an iphone 3gs version 4.2.1 (8C148a) with baseband 05.15.04, I have made the jailbreak with Redsn0w 0.9.6rc8 and the firmware of this version, then the corresponding reset, when I turn it on, the normal apple appears and later a little more than usual but it turns on only, through itunes 10 and loaded the files (photos and videos)….

    1- By not having access to Wi-Fi connection I cannot install cydia, the first time I was able to enter the menu but now it no longer shows me the menu ...

    2 - The issue is that the home button does not return me back, and every time I use an application I have to turn it off and on

    3 - And finally I have noticed that when charging the battery heats up.

    Can someone give me a solution in this regard.

    Thank you very much in advance I appreciate your help

    Hello
    I jailbroken version 4.0.1 a long time ago, I'm trying to update it to this new version but it won't let me. I had already installed cydia from the old jailbrek. Now when I do the whole process of this jailbreak, it does everything right until the quit window appears on the laptop, the iphone enters Vebose mode but it hangs on me and puts me at the end of everything, »panic: we ' re hanging on »…. Can someone give me a hand? por favor

    Hello, I have version 4.1 with jailbreak, now if I want to update to 4.2.1 do I have to redo jalibreak or just update from itunes?

  229.   shikamaru79 said

    what do you mean by:
    Remember that we recommend doing a clean restoration before use.

    If you need release, don't follow this tutorial.
    And another question, I will lose my already downloaded apps.

    Very good, Gonzalo!
    Let's see, sorry, after reading all your explanation (great, by the way!) And all the posts (especially your response to one of the posts talking about a case like mine, with the same baseband has puzzled me) no It is clear to me… can I jailbreak my iphone4, 4.2.1 with baseband 03.10.01? I have the iphone as it comes from the box, I have not touched anything and it comes as I explain. I am also new and I am not very clear about what to do. currently I have downloaded the gp for windows rc5, and when reading the readme of this file, the doubt comes back to me.
    Gonzalo, I would be very grateful for your help, because I really have been since yesterday, when the mv came to me looking on the internet and it scares me a little.
    Thanks

  235.   gnzl said

    MIGUEL, your iPhone can be jailbroken but not released for any company.
    .
    NICOLE, you have to do a CLEAN restore for it to work (you restore, then you jailbreak and THEN you put your backup)

    Hello people! I make a query, I have an iphone 3gs version 4.2.1 (8C148a) and SHSH 4.2.1, + 4.3b with baseband 05.15.04, I have jailbroken with Redsn0w 0.9.6rc8 and the firmware of this version, then the corresponding reset , when I turn it on, the normal apple appears and it takes a little longer than usual but it turns on alone, through iTunes 10 I loaded the files (photos and videos)….
    1 - And finally I have noticed that when charging the battery heats up.
    2 - I am using it in tethered mode, that is, I use the computer to turn it on, there will be possibilities of not doing this anymore ...
    3 - I would also like to know if I can release it to use with any company

    What steps do I need to do?

    EXCELLENT !!!! I'M ALREADY USING CYDIA!
    Thank you very much friend, I was really waiting for the jailbreak to be unthereted. It pulled my hair out every time I had to reboot with redsnow.
    It was very easy and very fast ... although I tried 2 times in the LOADER step, to install cydia.
    Thank you very much again!
    Do it without fear. I RECOMMEND!

    compadre look I tell you my experience ..
    I also have an iphone 3gs in 4.2.1 and I also jailbreak it with redsnow and then from cydia I installed the ultrasnow to be able to use it with any company ..
    The issue is how the version 4.2.1 stayed "tethered" that is, every time I turned it off, it went into iboot mode and lost the jailbreak and didn't turn on anymore ..
    The issue is this .. I had no other option than to get it out of iboot mode with redsnow by pressing the option «just boot tethered right now» and I got bored of having to turn it on like this and aberigue and I found this page (excellent!) and without deleting anything, leaving everything As I had it while I was using redsnow, it means with the cydia installed and the ultrasnow installed tmbn .. without turning off the iphone (because it didn't go into iboot mode) use the "greenpois0n" and I jailbreak it with this program and the iphone I rebooted as I had it before using the greenpois0n .. it started with the same applications everything the same even unlocked for all companies .. and now I can turn it off and on when I want .. so my iPhone was untethered ..
    I hope to help and hopefully I have been clear in my explanation .. since whenever I read the explanations of other people and it is never very clear to me ..
    greetings and good luck !!

    It worked the first time with the greenposi0n rc6.1 and the tutorial from here.
    Iphone 4 Telcel 4.2.1
    I comment what I did:
    1. Fully reboot.
    2. Make greenpois0n work as administrator (windows 7)
    3. When I did the steps to put it in DFU he told me to try again, I just pressed that button and the jailbreack button was enabled.
    4. Follow the tutor and ready.

  270.   Nico said

    Excellent and clear the gnzl tutorial. I only have one question. I have an iphone 4 with 4.1 with jail. To do the restoration, is it enough to synchronize it with iTunes or do I have to download some firmware and install it? Thanks

  271.   Carlos said

    Everything went perfectly but when I want to install the apps it loads them and then says that it cannot be installed because an unknown error 0xe8008001 has occurred

    Jose lillo! Thank you very much for the answer, I did not dare to do it, thanks to your answer I did it and it works perfect, except for 2 things… .. when I listen to music I only listen with headphones, the menu button does not work so download an application »QuickDo» to supplant it, but before doing the jailbreak it works fine… do you know if it has a solution? What applications do you recommend?

    Hello, I have carried out all the steps to follow on my Itouch 4g and I get everything as it says to me, the problem comes when the cydia appears, I give it to install and I get a black screen with the message "Initializing filesystem" (Cydia will exit when complete) I know what it means that the program is being installed and that when it finishes it may exit. Well, after this I get the "skull-apple" and then it takes me to the main screen, I think I already have it installed and when I put it back I get the Intalazing again. I know it says that it can be repeated

  327.   noeliaviles said

    Sorry, I hadn't finished, and it says that if it fails, repeat it again due to server overload, but if I haven't done it and tried more than 50 times, I haven't done it any and this still doesn't install to perform the step of downloading the instalus, has anyone last? Thanks in advance

    I follow the steps to put it in DFU:
    I press the Power button for 3 seconds.
    Pulse Home and Power at the same time for 10 seconds.
    I release Power and hold Home for about 15 seconds,
    Then the iphone turns off and won't let me perform the Jailbreak because the iphone doesn't turn on even with Power, the only way to turn it on is through iTunes and it becomes standard, that is, updated to 4.2.1 but without contacts, nor photos and nothing.
    Please a solution! .. I want to do the Jailbreak and I can't .. Thank you very much in advance ..
