These are instructions on how to upgrade your iPhone 4 or iPhone 3GS firmware without updating the baseband.

Step One
Create a folder on your desktop called Pwnage

Download the latest version of RedSn0w from here and place it in the Pwnage folder. Likewise, download the firmware you would like to upgrade to from here and place it in the Pwnage folder.

Extract the RedSn0w zip file to the Pwnage folder.

Step Two
Right click or control click the RedSn0w application that you extracted in Step One and click Run as Administrator from the popup menu that appears.

Step Three
Click Extras from the RedSn0w menu.

Click Even More from the Extras menu.

Click the IPSW button.

Choose the firmware you would like to update to from the dialog box that appears and click the Open button.

You will be asked if you would like to Prevent baseband update. Click the Yes button.

Step Eight
You will be told that Pwned DFU mode is required. Click the OK button.

Hi, after following this procedure, I get an unexpected error 2831, I want to upgrade an iPhone 3GS with BB 5.11.07 from 5.0.1 to any higher version, and no matter what I do, I get the same error. Any comments please? Win 7, last redsn0w version, already jailbreaked. Many thanks
