  • [Windows] How to Jailbreak and Unlock iPhone 2G Firmware 3.0 with RedSn0w
    This guide will teach you how to jailbreak AND unlock your iPhone 2G running 3.0 firmware using RedSn0w on Windows.

    I strongly recommend you backup and restore your iPhone 2G to 3.0 firmware via iTunes BEFORE you begin this guide. By strongly recommend I mean restore to 3.0 firmware.

    You will need RedSn0w 0.7.2 which you can download here along with the iPhone 2G 3.0 firmware file available for download here. You also need the 3.9 and 4.6 bootloader files. Download 3.9 here and 4.6 here.

    Once you have downloaded everything, extract redsn0w-win_0.7.2.zip to a location on your computer. You should see redsn0w.exe. Run it.

    Click Browse.



    Find your iPhone 2G 3.0 firmware file you downloaded earlier. Select it and click Open.



    RedSn0w tells you that the ISPW is successfully identified. Click Next.



    There will be a quick pop up.



    Select your options to Install Cydia and Unlock. If you don't need to unlock your iPhone 2G you can de-secelct Unlock



    If you are unlocking you need to located the 3.9 and 4.6 bootloader .bin files you downloaded earlier.









    Now that you have told RedSn0w where the bootloader files are click Next.



    At this point you should make sure your iPhone 2G is plugged into your computer AND turned off. Click Next.



    RedSn0w gives you instructions. We are entering DFU mode now. First hold the power button for 3 seconds.



    Keep holding the power button and start holding the home button for 10 seconds.



    Release the power button but continue holding the home button for 30 seconds.



    RedSn0w does its thing. Let it.













    Finally RedSn0w has finished loading everything onto your phone. You will see a pretty screen on your phone as it is being Jailbroken and Unlcoked. Don't mess with your phone while all this is going on. After your phone restarts you are done!

      And yes, I did restore it, not update it, and my iPhone even has more memory now, 7.03 GB, before it had 6.93GB.
      Any help?
      You just made the size of your root partition 500mb this time compared to 700mb, so you have less root size now and more total space, as opposed to the opposite. not a problem

      you don't extract the restore file because it is the ipsw file

      you only extract the redsnow zip file

      A note to others: Make sure cydia is on one of your main screens and not poofed or in a tray or categories somewhere.

      I jailbroke but was unable to do anything about it as I had no access to cydia because my phone's backup remembered that it was hidden and it doesn't install ssh by default.

      When I double click on the RedSnow zipped file a pop up comes up saying "Extract All" "Run" and "Cancel". I've clicked extract all, basically does nothing......and I've clicked Run, which brings up the option to select the IPSW file. The only issue is that it doesn't show the uncompressed IPSW restore file on my desktop when that window is up.....and yes, that zip file is saved on my desk top ???? IDK WTF I'm not doing right but I've never had this issue with Pwnage when I've used it in the past

      Yes, but I was wondering why with only SBSettings, Cydia (+coreutilities) and Winterboard i only have 98mb left Is it ok?

      Anyway, to everybody out there guys, mine is working perfect: SBSettings no problem, Mobile Substrate no prob, Winterboard 100%, Youtube no problem, only Maps is a bit glitchy cuz it can't find my location, everything else works like a charm. Even the ******* for 3.0 that let's u install cracked .ipa's works great

      As for the SSH problem, i found somewhere (I am not allowed to post the link I think) that with iTunes 8.2, apple disabled SSH through USB and it works only by Wi-Fi. However, I found this program (not warez, just a trial) which is said to work, didin't got it tested cuz I have an exam in 1h :P
      Here's the link.

      Any other advice I can give u is to follow the guide EXACTLY and take your time, don't skip over or rush into things.

      @Loyalty: Use Winrar and right-click then "Extract Here". I didn't come to any problems while extracting. U should have an .exe file over there, "redsn0w.exe" and 3 .txt files

      LE: For those of you who wish to use the .ipsw file from iTunes, just update iTunes to 8.2, connect your iPhone then select Download Only when it asks for updating to 3.0. Then locate your .ispw downloaded file in "CDocuments and Settings\"YOUR USER NAME"\Application Data\Apple Computer\iTunes\iPhone Software Updates". Note that Application Data is a hidden folder

      Hope it helps.

      To candyg12l: I used the iPod Touch instructions for where to get the ipsw.

      From that post:
      ------------------------
      iPod2,1_3.0_7A341_Restore.ipsw is the iPod Touch 2g 3.0 firmware file.
      iPod1,1_3.0_7A341_Restore.ipsw is the iPod Touch 1g 3.0 firmware file.

      On XP they are located in
      CDocuments and Settings\ YOUR USER NAME \Application Data\Apple Computer\iTunes\iPod Software Updates\

      On Vista the are located in
      CUsers\ YOUR USER NAME \AppData\Roaming\Apple Computer\iTunes\iPod Software Updates\
      ---------------------

      I just changed iPod to iPhone in each instance. My latest ipsw was right there. When redsn0w asked for one, I used the iPhone1,2_3.0_7A341_Restore.ipsw, which was created tonight when I upgraded to 3.0.

      Now, that being said, I'm having some problems with a number of jailbreak apps not working. I'm still working on them, though, and think that doing some SB restarts will help.

      Oh, yeah - the ipsw file isn't in the zip folder, as some seem to expect. I downloaded the one that modmyi has available, but couldn't get it to work. That's why I tried the other way.

      So, it's TWO downloads for jailbreaking, which is all I do. Not worried about unlocking.

      And to the folks having issues unzipping: Vista gives my headaches with that as well. I had to use a separate program to get the .exe to unzip properly.

      then

      Followed the steps again from Poetic Folly

      After many hours of searching and downloading the "iPhone1,1_3.0_7A341_restore.ipsw" links posted on the guide for redsn0w 2g iphone, I found that Windows Explorer wont download a usable file. The trick is to USE FIREFOX browser, enter Modmyi, then download and extract redsn0w AND the 3.0 firmware file. Only extract the redsn0w zip and Firefox will properly download the firmware file so that you can use it in its .ipsw form. Explorer breaks it up into small files and is useless! Firefox keeps it in its workable form with the "lego" icon/musical note. Once I ran redsn0w and told it where to look for the firmware, it successfully verified the firmware and let me proceed to jailbreak and unlock 2G iphone on 3.0 firmware. I hope this helps everyone who has been pulling their hair out all day.

      Hi Guys n Gals
      Got the same problem here as many others. Stuck on the "Waiting for reboot" screen!
      iPhone 2G Vista Ultimate 64
      iTunes restores fine, but redsn0w just sits there waiting. I can reboot manually, but then it sits waiting for the "last" reboot. Been an hour now!
      Any ideas out there?

      After some extra research I finally fixed my APN issue by going on cydia and downloading "APN editing" app, it added the missing "Celluar Data Network". Unfortunely now something else went wrong....I know right wtf. Anyways Cydia keeps crashing soon as I open it, sometimes I even get loading and then it crashes. I have done alot of internet searches and youtube videos on this issue. Apprently it was an issue back in 2.2.1 firmware, and I even tired to fix it the way they did by SSH. Well that didnt work. I even tired to re-jailbreak and Cydia is still crashing. Anyone know of a good way to fix this? Anyone else having issues with Cydia. Thank you everyone for the help earlier.

      SSH into iPhone using DiskAid. Works like a charm. Just change from the bottom left corner Root Folder or Media Folder, whichever you like
      And you can restore everything u backed up manually or themes or etc
