Advertisements

Dev team released Pwnage tool for jailbreaking and unlocking iPhone 2G, 3G with the 3.1 firmware. iPhone 3G users are advised to use Pwnage tool for retaining their current baseband. Most of iPhone user doesn’t owns a Mac and here is the guide to Jailbreak and Unlock your iPhone 2G/3G with firmware 3.1 All you have to do is download a custom firmware hotlinked below this custom firmware is created with Dev team Pwnage Tool that strips out the baseband update from the upgrade.

Note : Read the following before getting in to business.

  1. This guide is for those who pwned their phone last time, if you are not sure about your phone just restart it and check it boots with a custom logo(e.g. pineapple) or Apple logo. If boots with custom logo go ahead.
  2. Some people who redsn0wed their iPhone last time successfully restored their phone with custom firmware but 60% of Redsn0w user getting errors. So we don’t advise you to use this on previously Redsn0wed iPhones. However these firmware’s are baseband update free so you can try these at you own risk. Please read the Update Section below
  3. Read this guide twice or thrice before trying anything. If you have any doubt post a comment below, we’ll try our best to reply you as soon as possible.
  4. If you already updated your iPhone 3G to 3.1 non pwned or Apple firmware then you can’t enjoy UltraSn0w anymore.
  5. For iPhone 2G follow first four steps and for iPhone 3G follow the whole procedure.
  6. During the restore if you get any error then put your phone in DFU mode and try again or you can also downgrade to 3.0 with in from DFU mode.

_____________________________________________________________________________________

Step One : Download the custom firmware and extract to your desktop. These custom firmware are Jailbreaked and  contains Cydia for using the full potential of jailbreaking.

Download iPhone 2G 3.1 Custom Firmware : Google is your F.R.I.E.N.D

Download iPhone 3G 3.1 Custom Firmware : Google is your F.R.I.E.N.D

 

Please do not ask links to custom IPSWs in your comments, because the software in them is copyrighted by Apple. For legal issues we can’t link you for modified custom firmware.

Step Two : if the files you downloaded have an extension .001 and .002. Then you need a special open source (free) software HJSplit to join those files. Download HJSplit to join both the files – HJSplit for Windows Computers and HJSplit for Macs here.

Step Three : Put your iPhone in Recovery mode by following instructions.

  1. Turn the device completely off and disconnect it from cable/dock.
  2. Hold down the home button.
  3. While holding down the home button connect to a computer with a cable (easiest) or dock.
  4. Keep holding down the home button until you see a connect-to-itunes screen You are now in recovery mode.

Step Three : Launch iTunes 8.2, hold the shift key and then hit Restore button. For Mac hold Option key on your Mac and then hit the restore button. Make sure to hit the restore button.In the dialog box that pops up, browse the downloaded custom firmware file and let iTunes do it’s job. Once the upgrade is finished you haven’t need to jailbreak it again since it was already jailbroken.

  • If you get a 16XX or 21 error while restoring then follow the Update on bypass error 16xx below and re perform the restore process.
  • If you need to unlock iPhone 3G then follow the unlock instructions below.

_____________________________________________________________________________________

—- Update Bypass Error 16xx —-

 

Thanks to Andrew for the tip, iH8sn0w release iREB 2.2 for those who getting error 16XX while restoring, download iREB 2.2 for Windows or Mac from here unzip the tool to desktop.  To apply patch run the application select your iPhone or iPod then follow on screen instructions.

  • Place Your Device into DFU mode by following instructions
  1. Connect your iPhone to your computer.
  2. Turn iPhone off.
  3. Hold power and home together for 10 seconds (exactly).
  4. Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
  5. A few seconds later iTunes should detect your iPhone.
  6. If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.
  • Select Your Device in REB utility, it will take a few seconds to get a White and then a Red screen!
  • Then you may Open iTunes and Restore to custom firmware.

In the patching process you need to put your phone in DFU mode so must check our previous article on  Difference Between Recovery Mode and DFU Mode

Windows Vista and Windows 7 user note : Right Click > Properties > Compatibility Properties, Run it as Windows XP.

For Unlocking iPhone 3G only

Step Five : Make sure to set up your wireless network settings on your iPhone 3G so you will be able to connect to the software repositories in Cydia. Now fire the Cydia app it may requires restart first time.

Step Six : Click on the Manage tab on the bottom menu bar. In the Manage tab, click on the Sources button in the middle. You will need to add the source to the yellowsn0w repo to utilize the soft unlock.

Step Seven : Click on "Edit" on the top right, then "Add" on the top left. In the URL, type: the following url without quotes “ http://repo666.ultrasn0w.com/ “. When you are done click "Done" .

    Hey Guys,

    I have a few questions & hoping someone can help me. I bought a used iPhone for use as a skype/ipod/wifi device. I plugged into itunes on Jan/09/2010 and updated it, thinking nothing of it. I don’t plan on using it as a phone and I don’t want to. Well now it’s locked on me and displays “no SIM Card installed Insert a valid SIM with no PIN lock to activate iPhone. Not knowing what version it installed, I tried the steps above to Jailbreak it, but I’m not familiar at all with iPhones or any apple gear.

    I have a Windows PC and would like to use this phone without a SIM card or plan. Is there any way I can get this going without being able to enter the phone to find out the version, using a windows pc?

    Thanks for your help in advance!!

    Hi
    This worked perfectly on my iphone 2G AT&T locked iphone preinstalled with 3.1 update via itunes..

    I started with restore mode first.. by holding the home button and shift+restore in itunes to select the custom restore file. then after sometime the itunes throw-ed the 1604 error…so i forcefully restared my iphone by holding both power n home button for 10sec.. then my phone entered into the recovery mode loop..

    I downloded iREB 3.1 and installed the same.. then closed the itunes and patched the recovery loop first..( while patching it will ask u to install the libusb-win32-filter-bin-0.1.12.1 if it is not present in ur system.. if not pls download the same and install it…

    After patching recovery mode loop.. u will get a apple logo alone on the screen after restarting the phone…

    Now put the phone in DFU mode…follow the video instruction exaclty. the link is mentioned in the iREB itself..
    ( Note : if phone is in recovery mode u will c connect to itunes on screen… if in DFU mode u will c nothing on screen )..

    Once u are in DFU go ahead and select the iphone 2g after patching u will get the white screen and iREB will crash.. now u can open the itunes and it will automatically asks u to restore now select the custom firmware using shift+restore and upload…

    Now u will c some process bar in the itunes after 4-5 mins u will a process bar under apple logo in the phones screen.. in next 5 to 10mins u phone will come up unlocked and jailbroken..

    Thanks to devteam for the custom firmware…

    I have WinXP SP3.. iTunes 9.0.1.8.. iREB 3.1..iPhone1,1_3.1_7C144_Custom_Restore ~255MB

    I just upgraded my 2g to 3.1, but none of the new features are present on my phone. I originally jb’d and unlocked my phone using redsnow and cydia on 3.0. What would cause the update to not come with any of the new features that are supposed to be in 3.1?

    I have an iPhone 3G with 3.0 firmware JB & unlocked with Cydia/Icy. My iTunes is V8.2.
    I’m having a problem with my phone, and the only solution I have to fix it is to restore the phone via iTunes. When I start the process, iTunes warns that the phone will automatically restore with 3.1 firmware. If I allow iTunes to do this, will I be able to use Pwnage to rejailbreak and re-unlock my phone?

    Hey guys
    I’m new to all of this but here is my situation. I just bought a iphone 3g from a friend and the firmware is 2.2.1 with baseband 2.30.03 and bootloader ver 6.02. I just jailbroke with quickpwn but i know you cant unlock it with that baseband version with yellowsn0w. So my question is should i update to 3.1 with the custom firmware and unlock with ultrasn0w? will the baseband be 04.26.08 or 05.11.07? Also im with tmobile. please if anyone can give me some answers i’ll really appreciate.

    Sup guys, alright so I have an iPhone 3G running OS 3.0.1 and I have XP on my laptop. My iPhone is also jailbroken at the moment with RedSn0w. Now I read that if you used redsnow before you should wait and NOT UPGRADE to 3.1 and use Pwnage Tool right? Does anybody know if its safe to convert from OS 3.0.1/RedSn0w to OS 3.1/Pwnage Tool? Thanks in advance.

    @ Grexg

    Do you happen to know your baseband version ?
    You can know that by running fuzzyband downgrader app on your iphone..

    If its 5.8 then you can downgrade your baseband and then unlock it..

    I think you will also have to revert to version 3.0 which will be possible once you downgrade your baseband

    Read some forums regarding ” downgrade your iphone baseband to 4.xxx”

    Please let us know how it goes

    THanks

    I tried using fuzzybase band downgrader but it will only work with bootloader version 5.8

    @ Everyone, ok i hope this teaches us a good lesson about patience!, DO NOT jailbreak your phone until the official, Jailbreak release is out.
    Let the iphone DEV team prepare a bug free jailbreak for you. Until then hold on to your tighty whities!

    And for those of you thinking about updating to 3.1 firmware and already running a jailbroken phone, unless you want to go back to square one, stick with firmware 3.0 or 3.01 or previous firmwares.

    You have been warned!

    Hi. I have upgraded my baseband to 5.11.07 and I cannot download it. Is it possible to downgrade to 2.0 firmware and use a turbosim? Does the turbosim have anything to do with the baseband?

    or Can I load Fido iphone firmware to my iphone to accept my Fido sim?

    Fido is a carrier, but the phone is from another carrier originally.

    Hi,
    I unlocked my iphone 3G running on 3.0 firmware 3 months back and I was using it with a different carrier with no issues. Recently I upgraded the firmware to 3.1 using iTunes 9.0 and my iphone 3g got locked again. I use windows XP operating system. How can I jailbreak and unlock my iphone again?

    Thanks in advance

    I have jailbreak the iphone 3g with the instructions and worked fine but I can’t unlock it. ultrasn0w installation goes pretty smooth but when I insert the t-mobile sim, it’s say NO SERVICE. I don’t know what I’s wrong I am doing.

    Is there any hope for the 3GS. I got one about a week ago and being new to the IPhone, when I loaded ITune, it told me they was an update for my phone and to install it. Well I did, so you know the rest.

    Hi! I use Vista and I have an iPhone 2G and used redsn0w when I Jailbroke 3.0. I skipped 3.0.1 and waited for 3.1. Now, my iPhone doesn’t have the Pineapple logo, is it a necessity for your tutorial to work? Should I do this jailbreak now, or should I wait for redsn0w?

    Is there any magic way to downgrade the baseband form 05.11.07 to the one that can be unlocked by ULTRASN0W, or turbo-sim for that baseband version???

  78. diggityDawg September 18, 2009 Reply

    I’ve tried all of the hacked firmwares and they all give me error 1604 or 1600. I’ve got an iPhone 3G that has been jailbroken many times before, but I did update to 3.1 last week before I saw the notice that we shouldn’t update… So am I screwed now?

    thx – dd

    Hey i’ve got the solution for problem (1600).

    Just downgrade the iphone to 3.0 with DFU mode, jailbreak, add cydia and all that stuff and then upgrade the iphone with the custom firmware. It worked perfect with me. Good Luck!

    vinay,

    Hi

    Just a quick question; I have jailbroken my phone, used ultrasn0w to unlock it, but there is still no signal. Would this be the case if the phone was somehow “blacklisted”. I bought it cheap!!

    Is it important to put iPhone is DFU mode?

  85. Vinay September 17, 2009 Reply

    @ Detour nope only for iPhone 2G and 3G…

    @ Someone @Fkli222 possibly you haven’t pwned your phone ever before..

    @ USMC7372 yes this will break your MMS and tethering patch..

    i downloaded both files, joined them, shift+restore and it gets to preparing to restore and says error has occured. can i restore from 3.0 to 3.1 in DFU mode? or do i have to update to apples 3.1 first and then restore with joined files? im on 2g by the way

  89. Someone September 17, 2009 Reply

    This process did not work for me.

    I have tried 3 times, downloaded the file twice and still get the error “iPhone could not be restored”

  90. detour September 17, 2009 Reply

    So will this work for the Iphone 3gs? What do you recommend if someone already has their Iphone jailbroken on OS 3.0 and wants to update it to 3.1?

  91. tabii September 17, 2009 Reply

    Iphone 2G, when used DFU mode to restore, got the 1600 error
    then used recovery mode, got the 1604 error.
