Download Custom Firmware iOS 4.1 for iPhone 3GS [Windows/Mac]

Update : The latest version ofย Redsn0w (Windows) can enable that tricky DFU mode on Windows! Macs can use the Pwnage tool to create the custom firmware itself…

Warning : This isn’t for the faint of heart. I did not post a detailed writeup cos’ DFU mode is kinda tricky on this one. If you know what this is and what it means, go ahead and try this. All others, please wait while other Windows users verify this.

          1. recboot works fine, it reboots the device and again goes to same recovery mode ?

            I am really stuck with recovery mode, tried on almost 4 different pc/ mac ?? still no luck….

  1. please stop posting and adding custom firmwares, you make people test your beta and suffer.

    3GS without shsh blobs saved is impossible.

    long ago I used to get new info and software from this site, but now this site is some kind of rubbish.

    you know everything before posting shit by adding all custom firmwares that don't work.

    1. Hey! Please chill, I clearly mentioned in bold that DFU in Windows machines is different and may not work. There is a warning for a reason. I will take them down over the weekend after I personally test on other Windows systems in various scenarios. Thanks for taking the time to post your feedback.. Cheers!
