Hey guy if you can help me out it would be much appreciated. Anyways, so I'm trying to sell my iphone 3gs and decided before I did to erase all content and settings manually from the iphone. As the title says I'm now stuck in an eternal reboot cycle where it reboots and freezes for 10 minutes or so and then reboots and does the same thing again. I googled some other stuff and was able to put it into recovery mode (the screen where it says to plug into iTunes is recovery mode right?) and when it downloaded 3.1.3 to my computer from itunes and tried to install it gave me an error message. So now I'm back to where I was before and completely lost as to what I need to do. Things you may or may not need to know, Its a 16GB iphone 3GS that was running 4.0.1 jailbroken. I have both a PC and a Mac I can use. Let me know if any other specs are required and thanks in advance if anyone can help me.
