I just jailbroken my phone succesfully, than stupidly wanted to erase all content and now had to go to 4.0 because I could install the 3.1.3 anymore. Could you please give advice, after I got the error in itunes (1604) I went to terminal and did drag and drop with iRecovery. I typed in iRecovery -s but its tells me this: Reason: image not found, Trace/BPT trap. I do hope I still have the OS 4.0 beta.. How do I find out … the system profiler doesn't tell me anything. Thanks for your help …

Hi,

I am one of those who regretted upgrading my iPhone 3G from version 3.1.3 to 4.0. Version 4 drastically slows down the performance of my iPhone.

Now, I managed to put my Iphone into DFU but when I tried to restore it through iTunes, a message from iPHONE `SOFTWARE UPDATE appears and the message reads: iOS 4 Software Update!

There is nothing there for me to choose version 3.1.3 even after I simultaneously pressed the command key on my Mac Book and clicked RESTORE on iTunes. I certainly do not want iOS 4 to be restored on my iPhone. Could anyone of you there please assist me on this.

Thanks a zillion!

My 3gs simply restored to 4.0 again. Any suggestions?

In reply to Edwin. you have to specify the path (directory) to iRecovery. I accomplished this by dragging the icon of iRecovery from Finder into the Terminal window. Then I typed -s after that.

[…] enter, and then a bunch of text will appear on-screen. You should then add these lines from Brandon’s 4.0 downgrade post, but make sure you press enter after typing each one […]

In reply to robat19. you don't double click the file. you open up terminal from Applications -> Utilities. Then you type in "cd " followed by the path to the folder you downloaded the file to (e.g. "cd /Users/robat19/Downloads"). then run the commands as per the above instructions

Hey all. I was trying all this terminal business and it wasn't working. I tried using Blackra1n and it worked like a charm. When it says to wait for the phone to reboot, it didn't reboot on its own. I has to reboot it myself. Hope this works!

Hello. I just downgraded from OS 4.0 beta to 3.1.3 with my iPhone 3G. Thank you very much for the great info!!!

In reply to brandonsteili. Blackra1n won't finish normally, once the screen turns black, reboot the phone (hold power, or power and home until it does) - once it reboots it will come back and activate (if you have a legit phone to activate on a legit carrier).

In reply to Ryan.

Never mind, I figured it out. My iPhone was in "recovery mode" and I needed to put it in "DFU mode." For the dumb noobs like myself, be sure to read the following link before attempting to downgrade from 4.0 to 3.1.3:
