First you will need to create a folder on your desktop called "PWNAGE"
Download and install
iTunes 8 from apple. If you havent already.
For MAC:
You will need to download
PWNAGE Tool from-->
HERE
On that page is a step by step guide included, and the Program itself is guided as well. Just follow the directions, it has gotten so easy to use these newer tools.....
You also need
Bootloader Images 3.9 & 4.6 from-->
HERE There are firmware files on that page, but this site has them as well
HERE
You will need to get firmware 2.0.2 and 2.1
For Windows:
You will need to download
WinPwn 2.5 from --->
HERE
There is a guide on that page as well, but again the tool itself is guided.
Using the same
bootloader images and firmware files stated above
(2.0.2 & 3.9/4.6 BL)
Once you have gone through the 2.0.2 pwnage process you will need
Quickpwn 2.1 HERE
This is where youll use
v 2.1 and the 3.9/4.6 BL
Again this is guided, but you must use winpwn first to get to a custom firmware so you can upgrade to 2.1 with Quickpwn. There currently isnt a version for windows like Mac for creating 2.1 firmwares.
Place all applicable downloaded files in created Pwnage Folder. This includes when you create custom firmwares. You will always know where the files are, and so will your tools when they pull them automatically.
This may seem foreign to you, but just follow above steps and read the info in the links I provided.
I also believe v2.1 has been the best of the 2.xx firmwares. Highly worth doing!!!!
EDIT: I see there were a few posts before i got this posted, if you have a MAC use it, that cuts out an extra few steps currently.
