Recently, Apple seeded iOS 4.2 beta for Apple iPad and after installing iOS 4.2, you might face some incompatibility issues with your favorite iPad apps forcing you to return to old iOS 3.2.2 or iOS 3.2.1 firmware. If for any reason, you upgraded it to iOS 4.2 and would go back to iPad 3.2.2 or iPad iOS 3.2.1, then follow the steps below (for Windows and Mac users).
VERY IMPORTANT: This process is only for those who have already saved the ECIDs with SHSH to Cydia Server for iPad 3.2.2 or iPad iOS 3.2.1 and we are sure that you had saved it before the release of iOS 4.2
Steps to Downgrade iPad 4.2 to 3.2.2 or 3.2.1 iOS Firmware
- Connect your iPad to your computer.
- Turn iPad 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 device
Step 3: We need to make some changes in host file making iTunes to think that it is pointed to Apple servers, but in actual, we are going to change the address to Saurik’s server. To do so, Navigate to the path “c:\windows\system32\drivers\etc\” and open the hosts file in a notepad or wordpad. MAC users can navigate to the path “/etc/” and open the hosts file with TextEdit.
Step 4: At the end of file add the string “184.108.40.206 gs.apple.com” useful to redirect requests for certificates for authenticity that iTunes will make to the Saurik server. You may follow the steps below to do so.
- Open Notepad with administrator privileges and then right click on the icon of notepad and click on “Open as administrator”
- Now that Notepad is open Go to folder C:/WINDOWS/system32/drivers/etc and open the file
- Add the following line at the end of the document and save it: 220.127.116.11 gs.apple.com
- Navigate to Go -> Go to Folder and enter the path /etc
- Open the file hosts with TextEdit, add the following string 18.104.22.168 gs.apple.com and save the file to your desktop.
- Now return to the previous folder by following the same method and copy the text within this file by replacing the original file (If prompted for a password enter it and click OK)
Step 5: Now open iTunes and do a normal reset by holding down the SHIFT key (for Windows users) or Alt key (for Mac users) and clicking restore in iTunes. This will make iTunes prompt you to select the location for your downloaded iPad 3.2.2 or iPad 3.2.1 file. Select the ipsw file and click on “Open”.
Step 6: Wait till iTunes installs the firmware on your iPad. After the update process is completed, iTunes might show the following error messages: “The iPad could not be restored. An unknown error occurred (1004).” and “iTunes has detected an iPad in recovery mode. You must restore this iPad before it can be used with iTunes.” Press “OK” to continue.
Step 7: Your iPad will be stuck in Recovery Mode, showing that “Connect to iTunes” screen. To exit your device from Recovery Mode, download TinyUmbrella (Windows / Mac). Run it and the click on “Kick Device Out of Recovery”button. Your iPad will now restart normally.
