First of all, please read very carefully This article and if you understand what it is about and you agree, then you can follow the steps below to make a custom ipsw for your terminals.
Using this tutorial you will only be able to decode iPhone 3G/3GS NO MORE if you UPDATE to the 06.15.00 baseband of the iPad. This version of PwnageTool jailbreaks for:
- iPhone 3G – iOS 4.2.1 – untethered;
- iPhone 3GS (old bootrom) – iOS 4.1 – untethered;
- iPhone 3GS (new bootrom) – iOS 4.1 – untethered;
- iPod Touch 3G – iOS 4.1 – untethered;
- iPod Touch 4G – iOS 4.1 – untethered;
- Apple TV 2G – iOS 4.1 – untethered;
This tutorial has only a few guiding steps for those who know how to use PwnageTool. For the rest of you, the wait continues until tomorrow when redsn0w appears, which will also jailbreak iOS 4.2.1. My advice is WAIT UNTIL TOMORROW!!!
FOLLOW THIS TUTORIAL AT YOUR OWN RISK!
Step 1
Download PwngeTool 4.1.3 : [download id=”103″]
Download iOS 4.1 for your terminal here.
Download iOS 3.2.2 for iPad by here.
Step 2
Follow this tutorial to make a custom ipsw, but with the following mentions!
- DO NOT USE A COMPUTER WITH Mac OS X installed in VMWare!
- you must first load the ipsw for iPhone 3G/3GS, after which you will receive a warning message to which you press yes.
- after that you have to load the ipsw of the iPad to do the baseband update.
After you have done these 2 things, go through the steps mentioned in tutorial and finally put the phone in DFU Mode using PwnageTool! From VMWare you will not be able to do this.
UPDATED: PwnageTool released a custom firmware bundle for iPhone 3GS with old bootrom. With this bundle you can jailbreak these terminals on iOS 4.2.1 using PwnageTool and you will be able to avoid a baseband update.
TAKE THESE STEPS AT YOUR OWN RISK! I have not tried them!
Download this bundle of here.
On Mac, copy the PwnageTool application to the desktop, right click and select Show Package Contents, then navigate to Contents>Resources>Firmware Bundles where you will copy that Bundle.
After copying it, you can make a custom ipsw jailbroken and activated without baseband update for your 3GS with old bootrom.
On 3GS with new bootrom, the method does not work.
To jailbreak after using this custom ipsw you must follow this tutorial ignoring the baseband update.
