This are instructions on how to downgrade your original iPhone from 2.0 to 1.1.4.

You will want to perform this tutorial if you accidentally updated to the 2.0 firmware or you just rather be on 1.1.4.

To follow this tutorial you will need to have iLiberty (Windows, Mac), iTunes 7.5 (Windows, Mac), and the 1.1.4 firmware.


Step One
If you have Windows, uninstall iTunes 7.7 as well as Apple Mobile Device Support and then reboot your computer. Go to your Control Panel and use Add/Remove Programs or Programs and Features(Vista) to do this!

If you have Mac OS X, open Terminal from Applications:Utilities. Enter the following commands into the Terminal window:

defaults write com.apple.iTunes StoreActivationMode -boolean NO
defaults write com.apple.iTunes StoreGeniusMode -boolean NO
killall iTunesHelper
rm -r /Applications/iTunes.app
rm -r /Library/Receipts/iTunesX.pkg
rm ~/Library/Preferences/com.apple.iTunes*
sudo rm -r /System/Library/PrivateFrameworks/MobileDevice.framework

Step Two
Install iTunes 7.5 onto your computer using the download links provided above.

Step Three
Before attempting to launch iTunes 7.5 for the first time you need to delete or rename the iTunes folder.

Windows:
Rename the C:Documents and Settings**your user name**My DocumentsMy MusiciTunes folder to iTunes Backup.

Mac OS X:
Select the iTunes folder in your Music directory and rename it iTunes Backup. You press the Enter key to rename a file in Mac OS X.

Step Four
Launch iTunes by selecting its icon in the dock.

Put your iPhone into DFU mode by following these instructions.

iTunes will notify you that it has found an iPhone in recovery mode. Click the OK button.

Step Nine
Once the restore has completed you will get a 1015 error or similar.

If you get an error in the 1600s then try putting the iPhone into DFU mode and try again. You might also want to try a different USB port, remove your SIM card and then restart your system and if all else fails use a different computer!

Step Ten
Now you can use your favourite unlocking method to kick your iPhone out of restore mode and unlock it.

Below are some instructions to help you with the more popular methods; however, I would suggest using PwnageTool as it will downgrade your baseband.

Windows: iLiberty+, WinPwn
Mac: iLiberty+, PwnageTool

NOTES***
The first time I tried this I opened iLiberty+ with iTunes still open. It immediately kicked my phone out of recovery mode and then the application closed down. I reopened it and then was able to unlock successfully on my first attempt.

IMPORTANT***
PwnageTool will downgrade your baseband. There is no reason to use an alternate tool do perform this function but if you must... Here are instructions to use KiPhone to downgrade your Baseband.

Step Eleven
Select Software Update from the Apple Menu at the top left hand corner of your screen.

Select iTunes 7.7 from the list of software available for install and click the Install 1 Item button.

For windows users just reinstall iTunes 7.7 from the Apple website here

Step Twelve
Once installation of iTunes 7.7 has completed you can rename the folder iTunes Backup created in Step Three to just iTunes. You will then get your library back!

I only want to suggest a thing. Before Pass No. Six, I had to reinstall Apple Mobile Device, thats Quicktime. You did not cmment anythig about it in the tutorial and without that program the computer is not able to detect your Iphone. Thanks. :)

Hey, sure! the risks are very simple: buakcp all your data before attempting to jailbreak, in the very rare event that everything doesnt go according to plan, you can restore your iphone/ipad through itunes and it will be as if you havent done anything! now if you decide to go through with it, just download absinthe 0.4 for windows/mac/linux, according to your os and follow the onscreen instructions.Let me know what happens

In Step one it says to remove itunes 7.7 etc and rename folders....and then instal 7.5. Is it possible just to start off on a new computer with itunes 7.5 or is there something in 7.7 that is necessary after the removal and re-install of 7.5? thank you in advance for your help. :)
