So a friend was playing around with my iPad 3G which have been jailbroken (via jailbreakme.com) and installed a lot of apps via Cydia and Installous.
While installing a theme, the iPad required rebooting but turns out it would no longer boot up. It just hangs at the Apple logo. So I said goodbye to all my apps and had to restore to factory settings.
I was back after a couple of hours with a fresh iPad. However, I can no longer jailbreak the device since the iTunes I had already has the latest iPad iOS 3.2.2. I needed to go back to iOS 3.2.1 for the jailbreak to work.
So here’s what I did.
Step #1: Download iPad iOS 3.2.1 from the Apple site.
Step #2: Open and edit the host file using Notepad or some text editor. The file can be found inside C:WindowsSystem32driversetc and locate â€œhostsâ€ file. Add this IP address 18.104.22.168.
Step #3: Connect your iPad to your PC or laptop. Launch iTunes (unless it automatically does on its own).
Step #4: In iTunes, click the iPad from the list of devices on the left side of the window. Press and hold the left Shift key and then click the Restore button.
Step #5: iTunes will prompt you to provide the location of the firmware file you downloaded (iOS 3.2.1 download in step #1).
Step #6: Wait for the restore process to complete.
That’s it! Your iPad is back to iOS 3.2.1. You can down go to www.jailbreakme.com for follow the steps there.
