    Step 1 for Windows: Make sure you are logged in with administrator privileges. Navigate to C:/Windows/System32/drivers/etc and open the filed name hosts with NotePad. Add the following at the very bottom of the file: 74.208.105.171 gs.apple.com

    Save the file in the same directory.

    Step 1 for Mac: In Finder, go to Go > Go To Folder, and enter /etc. Search for the hosts file and right click on it to open with TextEdit. Add the following at the very bottom of the file: 74.208.105.171 gs.apple.com

    Click Save As to save the edited file on your desktop. Name the file hosts, and make sure to uncheck the box that says if no extension is provided, use .txt. Now drag and drop this edited file to /etc.

    Step 2: Download the firmware you want to downgrade to from our downloads section.

    Step 3: Put your iPhone in DFU mode. Launch iTunes and plug your iPhone in. Press and hold the home and and sleep button together for 10 seconds. After exactly 10 seconds, release the sleep button while still holding the home button. Keep holding the home button until iTunes tells you it has found an iPhone in recovery mode.

    Step 4: Now hold the Option key (Mac only) or Shift key (Windows only) while clicking the Restore button in iTunes. A dialog box will pop up and youll be able to choose the firmware you want to downgrade to, downloaded in step 2.

    Step 5: Your iPhone might throw some errors (ie. error 1004 or 1015). Thats ok. Its normal so dont freak out and just click ok.

    Step 6: Your iPhone should now be stuck in recovery mode, showing the connect to iTunes logo. To get out of this, simply download and install TinyUmbrella, launch it, then click onExit Recovery.

    Thats it. You should now have successfully downgraded your iPhone.
