24kpwn patch for Untethered Jailbreak for iPod Touch 2G is now available which I talked about yesterday, now I am bringing you another tutorial for the full Untethered Jailbreak of your iPod Touch 2G. This time I will be using the GUI Untethered Jailbreak software named Quickfreedom. This is easiest method for the Untethered Jailbreak of iPod Touch 2G, If you have used my previous tethered jailbreak tutorial then it can work upon that so you don’t have to restore to original firmware. As I am writing this my iPod Touch is being restored to custom firmware, and this GUI Untethered Jailbreak software is incredibly easy to use even for beginners.

How to Untethered Jailbreak iPod Touch 2G: Step by Step tutorial

LibUSB on Windows Vista

Pre Requirements for Untethered Jailbreak of iPod Touch 2G

* Free Download Jailbreaking tool QuickFreedom, 11.1 MB setup, Install it.
* LibUSB
* Original 2.2.1 firmware
* If you used my previous tutorial then you already fulfill all requirements.
* Also keep iTunes open but ignore it most of the time, you only need iTunes to restore the custom firmware from desktop

LibUSB on Windows Vista

I am writing this tutorial for Windows XP 32 Bit, Windows Vista 32 bit. Developer claims that it may work on 64-bit Windows Vista and Windows 7 too.

Mac users can use this software using VMware if iTunes is installed on that partition.

STEP 1

Install LibUSB and download original 2.2.1 firmware if you don’t have it. By simply running UrJTAG-xxx.exe, the executable and data files will be installed in your Windows program folder, usually some place like C:\Program Files\UrJTAG. It comes ready with support for JTAG cables that are directly attached to a parallel port. However, if you work with Windows Vista and want access to the parallel port, a driver for it has to be installed separately. It is available from

If you want to use UrJTAG with a JTAG cable attached to the USB port, actual cable drivers have to be installed beside UrJTAG itself. Usually, the cable vendor will provide the drivers. For example, drivers for Altera USB-Blaster come with their Quartus software. For FTDI-based cables, you need an INF file describing the cable and FTDIBUS.SYS and FTD2XX.DLL from FTDI (CDM drivers). If your cable shows up in the device manager without any warning sign, UrJTAG probably is able to talk to it.

Finally, UrJTAG additionally needs libusb-win32 to talk to some USB cables that are not based on FTDI chips (Xilinx Platform Cable USB, Segger J-Link). The so-called libusb-win32 filter driver is available from the project’s download page at Sourceforge:

2.4.2. Required software for compiling UrJTAG

To run autogen.sh, you need autoconf and automake, bison, and a recent flex.

The distributed source tarball contains source pregenerated with a current flex version; flex therefore is only needed if you want to compile code checked out from our Subversion repository. Flex 2.5.4a as it comes with most but the very latest Cygwin release cannot build the scanners for BSDL and SVF. Building these files requires Flex 2.5.33 or newer. The configure script will compare the available Flex version against these preconditions and enables or disables the related features.

Furthermore, libtool should be available, and “devel” versions of the following packages:

*

gettext
*

readline (not needed, but really eases interactive use)
*

ioperm (needed only for Cygwin)

2.4.3. Required libraries for USB support

For USB adapter support (including support for parallel port adapters attached to USB-to-parallel converters), one or more additional libraries are required.

Many USB JTAG adapters and USB-to-parallel converters are based on chips made by FTDI. To support these, either intra.net’s “libftdi” or FTDI’s “FTD2XX” library can be used.

On many modern Linux distributions, libftdi is available as a precompiled package and can be installed using the distribution’s package management system (e.g. “apt-get libftdi-dev” for Debian and Ubuntu). If it isn’t available or you don’t run Linux, you can get it from

Alternatively, you can use the FTD2XX library from the chip manufacturer FTDI. It is available for Linux and Windows. There’s more information about linking to that library in a Cygwin environment below.

All other USB JTAG adapters can be supported only if libusb is installed. There is a libusb-win32 variant that can be used in a
