Step-by-step Tutorial: How to Jailbreak and Unlock Your iPhone 3G Using RedSn0w 0.9.6b5 (Windows) [iOS 4.2.1]




UPDATE: Please think first, before you do something.

UPDATE2: If you have 05.13 baseband or lower – do not update to 4.2.1, use PwnageTool to create custom firmware!

This is step-by-step instructions on how to jailbreak and unlock your iPhone 3G on iOS 4.2.1 firmware using RedSn0w 0.9.6b5 for Windows.

IMPORTANT FOR UNLOCKERS
During this process you can update your baseband to the 06.15 version. If you are on 05.14 or 05.15 or higher you will need to do this to unlock. You do not need to do this for jailbreak only. Please read the following very carefully before deciding whether to do this.

  1. There is no way to come back down from baseband 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
  2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Don’t update to 06.15 if you don’t need to, you can just jailbreak without unlocking using this tutorial! Only update baseband if you need the unlock and you’re stuck on baseband version 05.14 or 05.15, and you’re willing to assume the above risks. You can find out your baseband version in Settings -> General -> About -> Modem Firmware.

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here or here. Save it in the Pwnage folder. Likewise, download the latest 4.2.1 firmware from below and place it in the same folder.

iPhone 3G iOS 4.2.1: iPhone1,2_4.2.1_8C148_Restore.ipsw

Extract the redsn0w executable from the RedSn0w zip file into the same folder.

Connect your iPhone to the computer and launch iTunes. Create a backup, since all your data on iPhone will be erased.

iPhone Dev-Team releases RedSn0w 0.9.6b5 for unlockers




redsn0w 096b5 341x400 iPhone Dev Team releases RedSn0w 0.9.6b5 for unlockers

The iPhone Dev-Team has released RedSn0w 0.9.6b5 for unlockers stuck at the 05.14 or 05.15 basebands.

The new redsn0w 0.9.6beta5 is out. It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS. It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now). There may be a long delay while it’s doing this (their servers are currently getting pounded).

You can download the new version of RedSn0w here:

Windows 7 and Vista users, please run redsn0w as Administrator in “XP Compatiblity Mode”.

We will soon post step-by-step tutorials.

RedSn0w 0.9.6b4: jailbreak for iOS 4.2.1 released




Redsn0w 096B4 RedSn0w 0.9.6b4: jailbreak for iOS 4.2.1 released

DevTeam worked hard for the last several hours and released jailbreak tool for iOS 4.2.1. It is redsn0w 0.9.6 b4.

As usual we remind all ultrasn0w unlockers please stay away from this official firmware. Wait for the ability to create custom 4.2.1 IPSWs that don’t update your baseband!

New redsn0w 0.9.6 b4 uses limera1n exploit and will successfully jailbreak all devices. The only problem is that it is a tethered jailbreak, which means you will have to plug it to a computer and rerun redsn0w on every reboot. This so called tethered or semi-tethered jailbreak. This condition applies to iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC model), iPod touch 3G and iPod touch 4G. Hackers are working hard to create untethered jailbreak for these devices. To use future untethered jailbreak you need to save SHSH keys for iOS 4.1 using TinyUmbrella utility or directly in Cydia.

Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC model) can be jailbroken-untethered right now using this latest version of RedSn0w.

You can download RedSn0w 0.9.6 b4 here.

Jailbreak iOS 4.1 with RedSn0w 0.9.6 b1 is now available for Windows




redsn0w 0 9 6 b1 370x400 Jailbreak iOS 4.1 with RedSn0w 0.9.6 b1 is now available for Windows

RedSn0w 0.9.6 b1 for Mac OS X was released a while ago. Today DevTeam created a version for Windows users. RedSn0w 0.9.6 b1 can jailbreak iOS 4.1 and iOS 4.1 running on iPhone 3G or iPod touch 2G.

You can download it here.

Redsn0w is easy to use:

  1. Download firmware here.
  2. Launch redsn0w 0.9.6 b1
  3. Select your stock 4.1 or 4.0 ipsw (you’ve already used this to update your device to 4.1 or 4.0)
  4. Select “Install Cydia” and any of the other options shown above, then click “Next”. Use DFU mode to install the jailbreak.

This is still beta, so there might be some problems:

Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub).

As usual DevTeam reminds us:

IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1. DO NOT USE REDSN0W

That’s because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple. If you do that, you lose the ultrasn0w unlock (possibly forever).
