Member: 1303863 Status: Offline Thanks Meter: 2 | Downgrade IOS 4.0.2 to 4.0.1 WITHOUT SHSH Blobs Step 1: Download the iOS 4.0.1 iPhone4 iPhone 3GS iPhone 3G , download iTunes from here. Step 2: Extract it with Winrar or Winzip to a folder on the desktop. You may need to rename the firmware file from .ipsw to .zip to be able to extract. Step 3: Open buildmanifest.plist file from the extracted files using Notepad (for Windows) or TextEdit (for Mac OS X) Search and replace all – 8A306 with 8A400. Do the same with restore.plist file and save both of them. Step 4: Now download iOS 4.0.2 and extract it using Winrar or Winzip. iPhone4 iPhone3gs iPhone3g iPad 3G and iPad WiFi 3.2.2 iPod touch 3G 4.0.2 Step 5: Drag all files extracted files from iOS 4.0.1 and replace them with all files of iOS 4.0.2. Step 6: Delete all ".dmg" files that end with 002 leaving files that end with 001. Then zip the new customized firmware and change it to ".ipsw" file, for example "downgrade.ipsw". Step 7: This step is optional, it helps you to ensure you get an SHSH file request for the future, but should not be necessary to just restore 4.0.1 * Locate "C:\Windows\System32\drivers\etc\" for Windows and "/etc/" directory for Mac, then locate “hosts” file and Open it in Notepad (for Windows) or TextEdit (for Mac OS X) then add this line at the bottom of the file and save it. 74.208.105.171 gs.apple.com [IMG]http://2.bp.********.com/_xODgVRIsPR8/THpyxj_ny7I/AAAAAAAABkA/xAO1rSeJkl8/s400/HostsFile.jpg[/IMG] Step 8: Connect your iPhone to your PC / Mac and launch iTunes (downloaded above) Step 9: Now, put your iPhone in DFU mode by following this steps, * Connect your iPhone to your computer. * Turn iPhone off. * Start iTunes. * Hold Power and Home buttons together for 10 seconds or so. * Release Power button but keep holding the Home button until your computer recognizes a new USB device. * iTunes will now recognize your iPhone . Step 10: Almost done, you will have to restore your iPhone to the firmware you have customized and saved in the above steps by Clicking on iPhone icon that appears in the left of iTunes then hold left “alt” button or “Shift” button on Windows from the keyboard and click on “Restore” then release the alt button. You will be promoted by a window to select the firmware, select your firmware file "downgrade.ipsw" you have made in the previous steps.

Now, You will be finally able to jailbreak and unlock your device . Note: While downgrading from iOS 4.0.2 to iOS 4.0.1 / 4.0, users may face error 1015 in iTunes, use Error 1015 Fixer download here to bypass from this error.

Note: If you got stuck in recovery mode, just use Recboot 1.1 |
