How to Downgrade iPhone 3.1.3 to 3.1.2

by Sebastien on February 7th, 2010

downgrade iphone 3.1.3 to 3.1.2

As always when a new firmware is being realeased, there is always a few unlucky people who “accidentally” update or restore to the latest firmware, thus losing their jailbreak and unlock.

In this case, you’d usually want to downgrade your iPhone from 3.1.3 to 3.1.2 simply by downloading 3.1.2 and SHIFT + Restore in iTunes so that you can choose your own firmware to restore to.

The problem is that Apple recently stopped signing all previous firmware versions making it impossible for you to downgrade.

Fortunately, Saurik has been smart enough to create a system to bypass Apple’s signature and making it possible for you to downgrade from 3.1.3 to 3.1.2. To do so, you will need to have your SHSH on file. To see if it’s on file, launch Cydia and look at the top. Mine says “This device has SHSHs on file for iPhone OS: 3.0, 3.1, 3.1.2″.

If you don’t have this, make sure you look for a link that says “Make my life easier” on Cydia. This will allow you to save your SHSHs.

This being said, downgrading an iPhone 3GS from 3.1.3 to 3.1.2 is easier said than done. It’s actually a pretty painful process that I detailed in a tutorial a few month ago. I originally wrote this tutorial to downgrade from iPhone 3.1 to 3.0 but the steps are exactly identical (MuscleNerd confirmed this).

If you’re one of those who need to downgrade your iPhone firmware, then check out my tutorial, or simply wait for the Dev Team to come up with a reliable jailbreak for 3.1.3. Something tells me PwnageTool is not too far ahead of us ;)

UPDATE: If you have an iPhone 3G, you can now downgrade from baseband 05.12.01 to o4.26.08.

UPDATE 2: This post is slightly outdated. Check out this page for the latest information about downgrading your iPhone.

    Seeing as Cydia is such a huge pain in the ass to navigate, could you give us a clue as to the location of the link that says “Make my life easier”?

    That would make our life a lot easier ;)

     
  2. Should be on the very front page of Cydia.

     
  3. @JFoundation says: February 7, 2010 at 8:28 am

    It’s not on my Cydia front page. Mine looks almost exactly like this http://cydia.saurik.com/ but with three links under the heading Developers Only.

    Hmm.

    please help me

     
  5. Isnt this just for 3GS ? my 3G has no “make my life easier” link…

     
  6. Please help! I started following instructions for jailbreaking 3.1.2 and as soon as I got in recovery mode, iTunes started telling me I have to upgrade to 3.1.3. I cancelled out – but now I am stuck in the itunes screen. What do I do??

     
  7. @JFoundation says: February 7, 2010 at 11:44 am

    @Blapp – That would go same for me on 3G.

     
  8. Can’t find “make my life easier” on cydia. Please help. Not on the frontpage or elsewhere.

     
  9. If I don’t have Cydia how can I downgrade pls reply

     
  10. say i Jb with 3.1.2, and installed Cydia, does it auto save my SHSH on Saurik’s server? or do i have to actually go in and do “make my life easier” ?

    i had it jb, but my brother didn’t know, he accidently use the itune on his comp, it says to restore, he restored it to 3.1.3 :( now it lost jb & unlock.

  12. obviously i missed something here because i tried the downgrade and got the 1505 error twice (which seems to be expected) but then my phone stayed in restore mode after disconnecting and trying a hard reboot. at that point do i run redsn0w? i tried blackra1n but then it showed no cell signal. how do i get it to reactivate after this? through itunes? do i have to change the hosts file back to normal?

     
  13. Sorry, I’m traveling and I don’t have time to answer comments. But please READ. It’s for 3GS only!

     
  14. please help me to downgrade my iphone i have on it 3.1.3 and BASEBAND 5.12 PLEASE HELP I WILL GIVE A PAYPAL GIFT HELP

     
  15. Go to the official dev-team blog here: http://blog.iphone-dev.org/ – there you’ll see that if you upgraded and your phone got SIM locked, you can’t currently unlock it any way. You have to wait for the hack.

    You can downgrade to 3.1.2 with jailbreak but then still can’t unlock.

    @vodhanz I believe it stores the SHSH files automatically because on my 3.1.2 3GS Cydia tells me it has these files on record even though I never intentionally saved them. Or maybe I just can’t remember?!

     
  16. Vinoth kumar says: February 8, 2010 at 8:13 am

    I was jailbreaking my iPhone 3gs 3.1.2 and ended up in upgrading it to 3.1.3 ! Now I don’t have a Cydia installed in my iPhone to downgrade it back to 3.1.2 !! Can anyone help me resolving this issue . Please .

     
  17. How can you open Cydia if you accidentally upgraded to 3.1.3 and the phone is not jailbroken anymore?

    Thanks.

     
  18. littledaemon says: February 8, 2010 at 11:47 am

    Exactly @ The Fly guy. I don’t understand what the author is talking about. If you’ve upgraded to 3.1.3, you’re not jailbroken anymore. I have a clean install of 3.1.3 and nothing else. I’m screwed. lol

     
  19. Exactly as above! It’s restored back to clean 3.1.3 and jaibreak is gonee :-<<<. Anyone can help? Tried downgrading with iTunes but they wont let me now. GHrr! Pls help.

     
  20. Read the tutorial. If it is what I read several months ago you have to point your iTunes to Cydia’s authentication server (which is why your SHSH’s have to be on file, if not this won’t work) and when you select the older firmware it matches what iTunes would expect and allow you to continue.

    So he’s telling folks to open Cydia BEFORE upgrading to check and see if your SHSH is on file. If you didn’t click the “make my life easier” link prior to upgrading to 3.1.3 then it’s too late but I don’t believe there would be any harm in following the tutorial and trying anyway… maybe you did and forgot.

     
  21. I am downloading the file to downgrade from 3.1.3 to 3.1.2 as I want my jailbreak back. I will let ya know if it works! I have a brand new 3GS 32GB bought last week from the Apple store.

     
  22. Cant downgrade, didn’t save my file. im f**ked right?
    Gaya22 apple!

     
  23. SHSH’, CYDIA all these things no one ever mention tell now give me a foooocking break its BS how do u even save your SHSH? its nothing but a big cash game for alot of them now all the suden we need to use cydia servers to back up our stuff mummmmmm , next step will be small monthly fees to mentain our servers after that u can upgrade so u can have more sopace or something foooock that all i wanted its an iphone and freedom but it does not look like its ganna happen anytime soon good job jay freeman i guess alot more money is coming now.

     
  24. IN DEV TEAM WE TRUST

     
  25. i accidentally upgraded to 3.1.3, and while this tutorial is all well and good, how am i supposed to download anything from cydia when there aren’t any 3.1.3 jailbreaks available? when i upgraded, it deleted all of my jailbreak apps.
    i tried running blackra1n, but it f***ed up my ipod and i had to restore, goodbye to all of my apps…
    how can i downgrade?

    (i have an ipod touch 3rd generation)

     
  26. Chris,
    You need to right click on notepad.exe and “Run As Administrator”. You should be golden after that.

     
  27. I do not see why a downgrade from 3.1.3 to 3.1.2 is seeming so difficult !! I did it on my iPhone 3G as below

    First of all let me confess that I just joined the iFucked community by upgrading to 3.1.3 using sn0wbreeze. It’s not their fault. When you create a new IPSW, you give some kinda hint as to where it is saved. sn0wbreeze saves the IPSW in the desktop – but I assumed that the same (original) IPSW was erased and jailbroken. There you are … I am well and truly into iFucked.

    To downgrade, follow these steps.

    1. Use iREB 3.1.2 to start up the phone
    2. Use Shift + Restore and select the jailbroken IPSW of 3.1.2
    3. If not AppSynced, use Rizwan’s Appsync or manually copy relevant files using DiskAid.
    … device will be jailbroken. Sometimes you may have difficulty in syncing the iPhone using iTunes. If this happens, follow step 4
    4. Try to downgrade to 3.0.1 using Redsn0w 0.8. Downgradewill fail, but apps can be loaded easily via iTunes.
    Checked so far … Cydia, Apps, Music, Contacts, Movies … all working.

    BUT THE DAMN DEVICE REFUSES TO ACCEPT ANY SIM OTHER THAN ORIGINAL.
    Where’s Ge0h0t … need another miracle from him.

     
  28. I downgraded to 3.1.2 but no signal… Please help me. I had signal in 3.1.3 official version. MY PHONE HAS NO SIMLOCK. I used blackrain and everything but there is no signal… Please help.

     
  29. littledaemon says: February 9, 2010 at 10:20 am

    @Oz…. yeah I had the same problem. That is because your jailbreak didn’t work well. Go back to iTunes & do a restore. It’ll do a restore to 3.1.3. That is the only way.

     
  30. Ah, you’ve got a great article there but I’m having problems. Something went wrong with blackra1n so I restored it unaware that I had to update as well. I had no choice so I did! Everything went back to normal. Also I did save the SHSH on rock and cydia so have I got to do all this just to rejaibreaj it?

     
  31. hey guys,

    i have an unbroken iPod touch 3GS.
    did i understand everything right to do the downgrade?
    first i do the jailbreak with blackra1n and not turn off the device after it (coz that would undo the jb). then i open the now installed cydia and choose the “make my life easier” option to save the SHSH.
    After doing that, i follow the tutorial to downgrade and everything would be fine.

    right?

     
  32. I hope that pwnage tool coming soon cause im tired of waiting
    and think im stupid that upgraded to evil 3.1.3

     
  33. Installed iblacklist on my jailbroke 3gs, the app killed my Iphone. Kept rebooting. No fix. had to restore phone and it installed 3.1.3. No way around it.

    Lost tons of apps.

     
  34. Wow. Max, the EXACT thing happenned to me cuz my dumb ho of a gf wouldn’t stop callin when I was with my other ho so I installed iblaclist-killed phone- only option was to restore. Now were f/;()d!!!

     
  35. Somebody please help me . I accidently restored and upgraded to 3.1.3 :( .. Now I have no JB at all. I have done all you have said there but it stops at the start of the restore and says something like your device can’t request summit. ( you know what I mean) what should I do to resolve this……..

     
  36. I am doing 3.1.3 to 3.1.2 on a 3GS and I am getting the “The iPhone “iPhone” could not be restored. An unknown error occured (1015)” error. When I “re-do the process all over again” do I put it back in DFU mode or do I restore right after I click “ok” on the error?

     
  37. try to update itunes first if you fail,
    i did it and works like charm ;)

     
  38. Not true I downloaded 3.1.3 without think and was able to downgrade to 3.1.2 using Shift+restore without any problems

     
  39. Hey im unable to get on cydia because i already updated. i was stuck on the apple logo and the phone wouldnt turn on so i had no choice but to restore and update it wasnt an accident. but does that mean i just have to wait for a 3.1.3. jailbreak???

     
  40. Hi,

    just got a new IPHONE 3gs, it came with the 3.1.3 firmware. The thing is that I can’t jailbreak this iphone, (snowbreeze not working), that’s why I don’t have cydia, and that’s why I want to downgrade my firmware, so please guys, any thoughts??

    have a great day!

     
  41. I did everything and it worked. And then I ran blackra1n and everything was fine except that the very purpose of my iPhone was gone – NO SERVICE! how do I resolve this. Please someone get back to me??????

     
  42. Halloo Zusammen.

    Ich will Jailbreak auf iphone machen aber es klappt nicht weil ich 3.1.3 version aufm iphone hab.
    wie kann ich es wieder auf 3.1.2 machen? Bitte Hälft mir….schreibt mir ein email. sevmeyanarsin–@hotmail.de

    Danke im Vorraus.

     
  43. @OZ

    I had the same problem BUT FIXED IT

    After upgrading to 3.1.3 due to an update stuffing things up, I had to downgrade using Cydia’s SHSH keys. Its here that I had the same issue as you where the baseband no longer worked with the firmware. To get around this I did the following:

    1) Create a 3.1.3 “jailbroken” ipsw file using snowbreeze.
    2) Downgrade to 3.1.2 (using Cydia modified host file)
    3) Jailbreak using blackra1n.
    4) Upgrade using itunes using the custom ipsw created with snowbreeze

    I now have a jailbroken 3.1.3 with the latest baseband. Personally I’m not worried about the unlock as I only with to use it with O2-UK anyway.

    Hope this helps!

     
  44. i need help im tryin to get it back to a 3.1.2..i got the firmware..i followed all the steps…but its telling me i cant restore it..why why why???????????????/help me

     
  45. hi, my iphone has been working well since i jailbroke it few months ago, but the wifi didnt properly all of a sudden(not able to detect any network). i then reset the internet setting and my iphone shut down after that. i tried to rejailbreak it again since my iphone 3gs was only tethered jailbroken. and then the picture of a guy did appear after i click the “make it rain” button, but it never go beyond that! instead, my iphone went back to recovery mode after stucking for few minutes in the guy’s picture! i have tried several times but got the same result! any help please!!!

     
  46. if your on 3.1.3 how do you get to cydia to get the saved files. you cant.

     
  47. Hey I Nedd Help On My iPhone 3Gs, When I Click Shift And Click RESTORE It Says Error 1600 And Sometimes 1604 Help Me Plz

     
  48. I need help wiping my iPhone clean and restoring 3.1.2 OS. My 3GS fone crashed(stuck on the apple screen) and I had to restore my fone. Apple loaded 3.1.3 WHICH I DIDN”T WANT and I lost all my winterboard customization. Is there anyway to restore WITHOUT going through APPLE? I don’t mind wiping the HD clean and loading ipsw files because I can restore from my last back-up. I really need help because I can’t use this garbage phone in the factory condition! If I can’t go back then I’ll sell this piece of crap and get a Droid!!!!!! The phone isn’t that great anyway and I only kept it for the apps and flexibility I had from the jailbreak. SOMEONE PLEASE HELP!!!!!!!!!!!

     
  49. MrBazUk
    Please can you tell me how to create a jailbroken 3.1.3 ipsw file. I have downgraded but have no service :-( . And im blonde as well so detailed instructions would be very helpfull. Thanks

    HOW TO CREATE A CUSTOM (JAILBROKEN) 3.1.3 IPSW FILE

    [These steps are intended for those who have downgraded their 3GS to 3.1.2 using Cydia's SHSH, but no longer have any service signal. This worked perfectly fine on my old-bootrom model 3GS, I no not know if it works with the newer bootrom models]

    1) Download Sn0wbreeze : (link)

    http://ih8sn0w.com/index.php/welcome.snow

    2) Download offocial 3GS 3.1.3 firmware directly from Apple: (link)

    http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-7472.20100202.8tugj/iPhone2,1_3.1.3_7E18_Restore.ipsw

    3) Run Sn0wbreze and follow the VERY SIMPLE on screen instructions

    4) Once your custom firmware file has been created, open iTunes and SHIFT+Restore to select it.

    Please feel welcome to email me direct if your really stuck. barryschleswick @ gmail.com

     
  51. Thank you for that MrBazUk

    For those who still have problem with no service,I just managed to get my service back by booting with irecovery before jailbraking it again. So iTunes can activate your iPhone before jailbreak hactivates it. Cant believe how happy i am. Finally after a week of misery :-]]]]]].
    Good luck.

  54. Hi, I bought a 3gs 3.1.2 yesterday and I tried jailbreaking but for some reason got stuck in the iTunes screen and now itunes says i need to restore and upgrade to 3.1.3… I tried shift + restore with the 3.1.2 IPSW but when i do that itunes says im not eligible. Can anyone help? is there a way around this?

     
  55. IM,
    Use iRecovery to get it out of the “plug into iTunes” loop and then if it’s not jailbroken still, use blackra1n to jailbreak.

     
  56. @Tom Lam

    Use iREB to get past these errors

     
  57. Matt,
    Thanks alot! Is there a safe site to download iRecovery from?

     
  58. Hi,nee to know how long you guys can jailbreak the new firmware 3.1.3.??

     
  59. Not sure if this helps anyone, I havnt got cydia as its my first break. I just restored 3.1.2 from my recycle bin, then did shift+restore in itunes and selected 3.1.2…..

     
  60. hmm… i acidentally updated my ipod touch 32gb to 3.1.3 via itunes,,, so what should i do 0.o this ”tutorial or whatever” doesnt show the file …

     
  61. i am trying to understand why it is for jailbroken phone. we have 3.1.3 firmware 3gs or any other phones. our problem is not being able to jailbrake it, so we need to downgrade that
    well we can’t throguh cydia since we dont’ have jailbroken phone. food for thought.

    How to tell if you have ecid shsh stored by saurik or = If you can restore
    After a week of attempts to try downgrading iPhone 3GS from 3.1.3 to 3.1.2 (there was an accident, having been downloaded from Cydia my WiFi stopped working, tried to reset the network settings and it got stuck in the boot without coming anywhere , panicked and updated in the belief that I could jailbreak yet anyway) so I’ve come to the following:

    If you do not have your ECID SHSH of Cydia = If you did not press “Make My Life Easier” button when it was on Cydia front, you can not recover because your SHSH is not saved. But even if you press the button so there is still a risk that it is not stored. :O

    I tried long and hard to restore to 3.1.2 by changing the host file for all the combinations available, but every time I got the message “This device isn’t eligable for the requested build.” I feared that my ECID SHSH was not saved, even though I was convinced that I pressed on Make My Life Easier.

    I decided to make my self sure
    HOW IT to see if YOUR SHSH is stored:

    1. Download the program from http://thefirmwareumbrella.blogspot.com/- Click on the Quick Download

    2nd Download usbview from
    http://www.ftdichip.com/Resources/Utilities.htm – Scroll down to “usbview is available for download as a. Zip file by clicking here.” Press the “here” to download.

    3rd Open up the Umbrella from the folder you extracted from the zip file, open up umbrella.exe if you have 32-bit Java or umbrella64.exe if you run 64-bit JAVA. If you do not know, try both, one of them will work.

    4th Change the “Device Version” to what you want to restore to, in this case, your iPhone / iPod touch model, and then 3.1.2.

    5th On shsh repository select “Sauriks server”.

    6th Now you want to get hold of your Ecid. Put your iPhone in restore mode, then open up usbview. Press the options and check “Config Descriptors” and “Location ID’s” Press F5 to refresh. Scroll down to the Apple Mobile Device … or something like that and press it. In the box to the right, a bunch of text to appear.

    7.Find where it says serial number, keep scrolling to the right until it will say ECID: 00000429349213492 or similar. copy all the numbers.

    8. Click up Umbrella again and paste the numbers you copied from usbview.

    9. Press Submit

    10th So, now the program will load. What it does is it looks for your SHSH on Saurik (Cydia) If it there it loads it home to your computer. This means that you can restore to 3.1.2 without any problems. However, if it says “couldnt find SHSH for the model and so on.” then you have not saved your SHSH at Saurik and can not restore to 3.1.2.

    I have the misfortune of not having my SHSH saved at Saurik, so I have to unfortunately wait until there comes a method for jailbreaking 3.1.3.
    This will probably save a lot of time for you.

    GOOD LUCK

     
  64. A simple way to downgrade without shshs. follow steps:-

    1. Open itunes and Click on restore with Holding shift and choose 3.1.2 firmware
    2. It will STUCK on preparing for restore, don’t lose temper
    3. Close itunes by opening task manager ( by holding ctrl + alt + delete) and end the itunes program,
    4. now at this point you can see your iphone with A Deadly black screen
    5. Open up itunes and Again choose Restore and 3.1.2 firmware
    6. Itunes Extract and Update it automatically
    7. Dance

    or simply on 3.1.3 go to ERASE DATA AND RESET ALL SETTINGS, in settings
    and restore to 3.1.2

     
  65. hi Sebastian, good day,

    3GS Downgrade 3.1.3 to 3.1.2

    - my system is winxp sp2
    - my itune is 9.0.2.xxx
    - i successfully done a few 3gs downgrade
    - i have shsh 3.1.2
    - i know irecovery to auto-boot for radio signal

    ** one thing i dunno is why i have a 3GS always giving me 1604 error after long time of “preparing to restore”. the umbrella and tinytss working great, in fact i did a few already, but somehow got one device really hate me. the progress bar on iphone just dun want to proceed and give me 1604 error!!

    ** i also tried multiple times of dfu
    ** i also tried multiple times of recovery mode

    any expert can give me some advice ? just dun understand why ?

     
  66. i didn’t get a shit. hey, author! you’re a fucking loser! this doesn’t work. it’s absolutely impossible to downgrade the iphone. so shut up or i’ll find you and shag you into your eye-socket

     
  67. After Jailbreaking and unlocking my iphone 3G (3.1.2) using blackra1n, I deleted it the blackra1n icon from my phone. All went fine. I realized later that I missed installing Cydia on my phone. Now I tried rejailbreaking using blackra1n n number of times, but the blackra1n icon just doesn’t show up on my phone. How can I get Cydia ? I do not want to restore since it pushes me to a 3.1.3 version. When I tried using shift+restore, it actually opened a browse window and prompted me to select an ipsw, I dint have any … Help…how can I get Cydia ?

     
  68. This downgrade wouldn’t work for an iphone 3gs running 3.1.3 (7e18) model: MC135LL baseband 05.12.01 that has never been jailbroken prior and does not have Cydia installed on it? There is currently no method by which to jailbreak under these conditions? Am I forever doomed because I upgraded to 3.1.3 and got on board late to jailbreak?

     
  69. Weenyhands,

    you are correct. There is no way for you to jailbreak at this point. And they are not gonna release the jailbreak. You’re just gonna have to wait for the next big firmware release.

    Guys,
    I was able to downgrade my Iphone back to 3.1.2. However I can only use as IPOD now. My unit is IOphone 3G and I would like to know how to unlock my phone again. Do we have a software to unclock it? How does a steal SIM work?
    Please let me know your thoughts.

    Philip

     
  71. HELP!!!!!!!

     
  72. So i have an unlocked iPhone 3g on 3.1.2. Recently something happened to my iphone, it freezes on the screen with the apple logo. and i read somewhere that the only way to fix it, is to restore it. but when if i restore it, it will automatically update to 3.1.3 meaning it won’t be unlocked anymore.
    Can anyone help me please?!?!?

     
  73. Just wondering if I am messed up regarding my iphone. I have a 2g 2.2 unlocked/jailbroken with quickpawn about 1 year ago. Tonight I went into the Mibbit IRC chat room, in there someone said to upgrade using Itunes to 3.1.3 then use redsn0w. and it seems like that is not correct.. I have Tmobile so when my sim card is in Itunes says can not ativate. And on my phone it is in a different language and I can only make an emergency call.

    I hope that there is something I can do. thank you in advance. :)

    @PhDizzle… I had this problem yesterday. I have a 2G 2.2 unlocked/jailbroken and upgraded to 3.1.3 on itunes. Plus I have Tmobile. So I couldn’t get into Itunes and my phone was in another language where I could only make a 911 call. This is what I had to do for my 2g phone. I don’t know if it works for 3g or not….

    1. If you can’t get into Itunes. You can go to this page and do one of the methods: DFU mode

    http://thebigboss.org/guides/dfu-mode/ I used method 1, read thoroughly.

    2. To be able to restore. You can download this on your desktop:

    http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-7268.20091008.32pNe/iPhone1,1_3.1.2_7D11_Restore.ipsw

    3. Connect your phone and then in itunes hit the “shift key/click restore” then browse to the .ipsw you just downloaded on your desktop and select it.

    Follow the instructions on the screen. Just click add “cydia”. then go to the different prompts and you should be set.

    Remember this is for 2g iphone. I think the DFU mode will work for all the generations.

    Hope this helps someone.

     
  77. wouldnt you like to know says: March 3, 2010 at 11:29 am

    soggy shit mate your chedder reckons its 3.1.3 to 3.1.2 but in actual fact the smelly cheese is really 3.1 to 3.0 what the f… you chattin stop chattin bare wetness and sort this shit out mate.. SERIOUSLY DUDE!!

     
  78. I mistakenly upgraded to 3.1.3 and found a way to downgrade to 3.1.2 easily on an iPhone 3G with baseband 05.12.01. Jailbroke it again with ease using Blackra1n. (I dont unlock so I don’t know if this is possible)

    Shift restore in itunes to 3.1.2 – It will fail. Your iPhone will go into recovery mode with the itunes logo and usb cord pictures.

    Download iRecovery (for windows or Mac – google it) use this software to take the phone out of recovery mode. When it reboots – > 3.1.2

     
  79. @Reeonimus

    Sorry to sound skeptical mate..But I don’t think that’s possible since I tried it out. But then again I might have missed something. Could you be more detailed?

    If your method works, it would be a great help to all the users like me who upgraded by mistake!

     
  80. I got a new iPhone 4 weeks ago and connected it to iTunes. It made a back up but then I mistaken updated to 3.1.3

    I now cannot find the original back up file which was 3.1.2 but if I could would I be able to jailbreak my iPhone

     
  81. Thanks man u jus saved my life =)!

     
  82. Can someone help me out please! I was out on a walk and was going to make a call on my jailbroken 3gs 3.1.2 unlocked iphone. But it said there wasnt any connection so i turned it off and then turned it on, but when it was starting up it got stuck on the apple logo and now I dont know what to do.

    Can I restore my phone in itunes with the 3.1.2 firmware? Im sure I pushed the “make my life easier”-button in cydia. I need jailbreak and unlock. Can i restore it with 3.1.2 and then jailbreak again as usual? And HOW do I do this?

     
  83. The APPLE and all the fucking iPhone OSs are such a pain in the ass, they always kill the spirit of a developer. Now, should I concentrate on my coding or grading up the iPhone OSs. Every three months they come up with some stupid idea that is incompatible with all the ideas they ever had.
    Sometime I wonder if their are retarded monkeys with 10 balls working at APPLE, who don’t wanna follow the standard protocols!

    BTW, how did you all got such cool-devil-looking avatars? or is it random default for anybody who doesn’t has a gravatar yet?

     
  84. hi,
    my brain is melting, seriously..

    yes im new to all this.
    but i understand the concepts.

    please someone help me :-)

    i have bought an iphone 3g
    its 3.1.3 on 5.12.01
    it wont sync with itunes,
    when i switch it on it comes up with the connect to itunes logo and lets me go to make an emergency call only.
    it will go into recovery mode.
    itunes does see it but wont show me whats on it.

    can i currently do anything with it?
    even if i can just use it as an ipod i will be happy :-)

    is there any software that will reconfigure it without itunes?
    or can i downgrade it with redsnow in its current state?

    i have linux and xp

    appreciate any help
    thanks

     
  85. hey did you registered it with iTunes, you first of all need a SIM card to activate it, and that too of a supported provider.
    You need to check out with the dealer who sold it to you.
    look in here http://www.apple.com/iphone/how-to/index.html#get-started.registering-iphone

     
  86. Aloha,

    Received an iphone from brother 3g 8 an tried to run to see if it would work. Already have a 3gs. This one is for the wife. anyway put in my sim card an it tells me i need to register the phonne w/ at&t . It ask for number, zip and last four s.s . an then it says need to pick a plan. Is their an way around this or do i need to call att to get a password or something…

    Any good advice,

    tk

     
  87. hey guys,just wanted to confirm if this would work on iPhone 3G too,as i dont see ¨make my life easier¨ in cydia,at the moment everythins workin fine for me as am on 3.1.2,but just incase i have a problem,so wanted to know if there is a way to restore 3.1.2,or downgrade from 3.1.3.

     
  88. ThisIsBullShit says: March 17, 2010 at 9:32 pm

    I can’t believe this. Apple sucks so much ass. You can’t downgrade, you can’t jailbreak, you can’t do shit. All you can do is wait for someone to create a 3.1.3 jailbreak. So while we wait wait wait wait wait and read this rediculously long list of comments, it’s makes one get more and more pissed off at the fact you could have summed it up and saved everyones time by posting the simple truth. YOU CAN’T DO IT. So in the meantime, all you do is wait. Apple just wants control of YOUR property. What a fucking monopoly. You don’t see them making a Mac vs. PC commercial about this one do you???

    To the host of this page . . . . You’re a fucking dildo. You could have saved everyones time by telling the truth . . . . . . it can’t be done.

  89. You candowngrade from 3.1.3 to 3.0.1 – 3.1 – 3.1.2

    i’ve tested successfully on iphone 3G.

     
  90. my iphone is in recovery mode i accidentally upgrade to 3.1.3 n i want to downgrade to 3.1.2

     
  91. Hi

    i have downgraded from 3.1.3 to 3.1.2 on my 3gs 16gb but now i get no service… what do i do …

     
  92. i need help says: March 21, 2010 at 6:32 pm

    what if i dont have cydia (cuz i restored and updated ) and need to downgrade???
    i need help plz

     
  93. I did downgrade my iPhone, but now the iTunes logo show up and dont let me do anything. Than I conect it to iTunes and it says that I have to update to 3.1.3 to keep using my iPhone.

    What to do now? How can I keep using without upgrade again?

     
  94. Can someone help me out please! I was out on a walk and was going to make a call on my jailbroken 3gs 3.1.2 unlocked iphone. But it said there wasnt any connection so i turned it off and then turned it on, but when it was starting up it got stuck on the apple logo and now I dont know what to do.

    Can I restore my phone in itunes with the 3.1.2 firmware? Im sure I pushed the “make my life easier”-button in cydia. I need jailbreak and unlock. Can i restore it with 3.1.2 and then jailbreak again as usual? And HOW do I do this?

     
  95. Awesome! Simply awesome. Thank you very much, saved my ass when my 3.1.2 comm center crashed and i was not ready to go 3.1.3 yet.

     
  96. Soo… What happens if my iPhone was restored to factory defaults, with the 3.1.3 firmware, deleting Cydia? I don’t think my SHSH files were ever saved or anything. Am I screwed?

     
  97. a quick question, would i need to follow the “downgrade firmware” tutorial BEFORE downgrading my baseband? I do have an iPhone 3G.

    also, now that i currently have 3.1.3 do I download one of the three jailbreaking programs mentioned above and THEN do the downgrading of the firmware and baseband?
    I NEED to get 3.1.2 badly because i want the MyWi because my current ISP, WildBlue is awful and i am in desperate need of faster internet… for the record, satellite is the only internet available besides dial up but i DO have 5 bars 3G service so like i said this would be simply amazing for me.

    -Much Thanks.
    Hope to get this working!

     
  98. I want cydia

     
  99. i have a mc model 3gs new with a new baswband nd firmware 3.1.3. can i degrade it nd jailbreak? please help nd suggest me! ! !

  101. Help!!!! I accidentally upgraded my iphone 3GS to version 3.1.3. I’ve follow the steps and i got error 1600. Please help!!!!!

     
  102. I was able to successfully jailbreak my phone that was previously updated to 3.1.3. After hours of trying blackrain and snow. I installed a 3.1.2 firmware version with an 10.15 error. Installed blackrain after ignoring the error and noticed everything worked but my att wireless signal. Clicked the blackrain icon on the phone and installed cydia to help ensure the phone was unlocked then I used Snowbreeze to upgrade the firmware to 3.1.3 and viola everything worked including my Att wireless signal. Hope this helps those of you who are using 3.1.3 and want to jailbreak your phone. You can’t jailbreak your 3.1.3 unless it has been broken in 3.1.2…very important.

     
  103. I tried to downgrade to 3.1.2 but it didn’t work and now the phone is stuck in DFU mode – I can’t get to it to turn on anything.
    Does anyone haveany suggestions as to how to get it out of this mode?

     
  104. I Successfully downgraded to 3.1.2 from 3.1.3 without having an SHSH or whatever on file. Will tell via email hopefully it will work for you aswell. Lockdown09@yahoo.com

    oh and i successfully downgraded my baseband aswell.

  112. Hi,

    I had my shsh saved on Cydia. I just successfully downgraded my 3gs 3.1.3 on 5.12.01 (Old Bootrom) Its now 3.1.2 and obviously the baseband is still 5.12.01. I can jailbreak it with Blackra1n, I have full reception & I can make phone calls fine. The ‘3G’ logo is on the top bar yet I cant get the internet other than Wi-Fi. Is this supposed to be the end result or am I missing something. Is there something on Cydia that can rectify this.

    Thanks – Please let me know

    @Callen

    Do you see any sort of error when you try to use the internet without WiFi?
    Very likely your data profile is screwed up. I suggest you goto this website :
    http://www.iphonedownloadblog.com/2009/08/29/could-not-activate-cellular-data-network-you-are-not-subscribed-to-a-cellular-data-service/

    Read the instructions, generate a profile for your provider and install it. In my view, that should get you running.

  115. if anyone knows how to downgrade 3.1.3 to 3.1.2 helpp me asapp.

  116. Thanks littledaemon, but re-installing and trying a few other things, the thing that worked was to simply Reset Network Settings.
    I think I synced with itunes after the jailbreak and that gave me my old and incorrect network settings or something.
    Finally, I have a Cydia on a 3gs downgrade with a 5.12.01 bootrom.
    Thanks anyway mate

    Hi Everyone,

    For whatever reason you want to downgrade iPhone firmware, follow the instruction from this guy here http://www.iphonedownloadblog.com/2009/09/15/downgrade-iphone-31-to-30/. Even though this guy is made for downgrading from iphone 3.1 to 3.0, it doesn’t matter. At the step where they asked you to select the firmware, just use the firmware for 3.1 or 3.0 or whatever firmware you want. Have fun.

  132. Only the 3Gs needs the SHSH to be stored on file

     
  133. DKindaFLESH says: May 26, 2010 at 3:29 pm

    I downgraded my iPhone 3G by restoring it with iTunes from 3.1.3 to 3.1.2 on Windows. Shift & click restore. Select 3.1.2 and restore. You should get the 1015 error. This is easy to fix. Your iPhone should be at the emergency call screen. Go to google and google blackra1n and go to blackra1n.com. Save the file to your desktop. Now google blackbreeze. Go to redmondpie.com and look for the link to download. Save it to your desktop and use blackbreeze on blackra1n. Connect your iPhone and run blackra1n. This will activate your phone.

     
  134. DKindaFLESH says: May 26, 2010 at 3:30 pm

    If you only need to jailbreak, use Spirit. That is easy and fast.

     
  135. DKindaFLESH says: May 26, 2010 at 3:32 pm

    To use spirit, your phone must be activated.

    I’m not really sure you can do anything to fix current location. Make sure it is not restricted or off. If it is neither of these, it could be a hardware problem with the gps chip in your phone or the firmware is messed up. If possible, just restore to 3.1.3 or 3.1.2 and jailbreak with spirit or blackra1n.
