Hey guys, in a bit of a pickle (Only myself to blame for being impatient/inquisitive)... So I upgraded my 3gs firmware to iphone beta 4.0 beta 1, while everything works pretty good, and I COULD wait til the official 4.0 releases I just figured I would sell my 3gs to afford the new iphone coming out in the next few weeks, so here is my problem, I have found directions on using a mac to downgrade but only found one site with directions on how to do it with PC, BUT in the comments half the people say it worked and the other half say they are bricked until they get to a mac to finish the process... So here is my question to my fellow TA'ers, Does anyone know 100% how or if even possible to downgrade 4.0 B1 back down to 3.1.3 using a PC? Thanks! 1337B P.S. - These are the pc directions that I'm too scared to try... Steps to downgrade iPhone 4.0 firmware to 3.1.3 Step #1 Extract the archive iRecovery and bring the application on your Desktop. Step #2 Install libusb-win32-filter-bin-0.1.12.1.exe and keep the file on the desktop. Step #3 Connect your iPhone via USB and put it in DFU mode (hold down the button Power and Home for 10 seconds then release). Step #4 Restore and manually load firmware 3.1.3 (by pressing Shift + Restore and select the firmware you downloaded previously). Step #5 Towards the end of recovery, the procedure will stop and return the iTunes error 1015. Neglect it. Step #6 Click OK on the pop-up, Close iTunes and run the console by typing the following commands: cd Desktop (or folder where you copied iRecovery) iRecovery.exe-s setenv auto-boot true saveenv fsboot exit Step #7 Unplug the iPhone from your computer and restart it by pressing the Power and Home until the Apple logo appears. Once turned on, connect to your computer, activate it and use it normally. Voila! The downgrade from iPhone OS 4.0 to iPhone OS 3.1.3 is successfully completed.
and this would work on the new baseband with 4.0? Don't mean to ask dumb questions but I have no idea what I'm doing, could you by chance give me a quick rundown/tutorial on what I would need to do?... I think selling it jailbroke would be more conducive then selling it with a broken 4.0 FW... Thanks!
