  • Downgrade from 1.1.1 to 1.0.2 POSSIBLE NOW!
    KMAC over at hackint0sh has found a way to downgrade from 1.1.1 to 1.0.2. Here's the skinny:
    • Start iTunes and plug in your iPhone which is running the 1.1.1 firmware.
    • Hold down the Sleep and Home button for 10 seconds. Allow the phone to power off, but keep holding down the buttons. After 10 seconds, let go of the Sleep button, but keep the Home button pressed until iTunes sees your iPhone. The screen on your iPhone should be displaying nothing right now.
    • iTunes will ask you if you want to restorea. Hold down Option or Alt, I forget which (Shift if you are in Windows), and click restore. When iTunes asks you what file you would like to restore from, navigate to your 1.0.2 folder. You may have to rename that file to .zip and uncompress it. It will begin to restore.
    • When it completes, you will get an error. The iPhone will display the yellow triangle on the screen. Leave iTunes open, and run AppTapp. This may give you an error, but you should see the "Activate iPhone" screen after.
    • Run AppTapp again. If the iPhone isn't being recognized, restart the computer and then run AppTapp for the second time.
    • Congrats! You now have 1.0.2 again! iNdependence and all other modding apps will now work.
    This has been verified with iTunes 7.4.3.1.

    UPDATE: Not confirmed yet, but for those having the "incorrect SIM" issue after dowgrading, try this (thanks, Doerr)

    Just turn off the phone, take out the SIM card, turn it on, and when its done put it back in.

      Ok so I downgraded to 1.0.2 from 1.1.1 and it works. Did independence and unlocked it. So I installed App Tapp (osx) and it kind of worked, downloaded Community Sources it worked, but when I downloaded BSD Subsystem it gives me this error ( Error during install script execution!) I don't know where to go from here, should I just reformat the phone again to 1.0.2 and reinstall App Tapp. ( Because maybe it didn't finish installing completely) Or delete App Tapp (How?) note* it took a while for Tapp App to actually sign on to the server(s), upload all of the applications that are available, also it's missing some (a lot ) OpenSSH does not show up. The same "Error during install script execution!" Came up when I tried to install Navizon GPS. Any takers?

      You shouldn't have to. iTunes should unzip it for you, thats ok.

      Hey there, I'm new to the boards. First off, Thank God for this. I stupidly upgraded to the new firmware. I have a few questions about this process. I'm a noob, so please bear with me.

      I'm running on a mac. I have iTunes 7.4.2. 7.4.3 is for windows, as it states on apple.com. My questions are-

      I hold down both buttons on the phone while on the dock, let go of the sleep button after 10 seconds, and let the home button go after iTunes recognizes the phone. My phone still shows the 30 pin connector/itunes image. what am I doing wrong?

      on step 3, I have the 1.0.2 folder on my comp and I am wondering exactly what file I am choosing to restore from. is it a folder that I am renaming and then choosing, or is it a file?

      That's really it. please e-mail me ([email protected]) or reply to this message. Any help will be greatly appreciated

      -Running on 1.1.1 and feeling retarted

      I was having the same problem downloading the 1.0.2 file with safari, it would automatically uncompress it (unzip it) So I just re-downloaded it with fire fox and it worked. It was untouched. In other words just download it with firefox and that should do the trick, Ok now back to my question. Error during install script execution! Check post back three or four I needs help PLZZ.

      Well, everything worked for me. I just need to get my phone unlocked, which I cant because my baseband is still not downgraded. Hopefully the solution will be released today.
