    Default Can't downgrade 4.2.1 to 3.2.2 - its killing me
    Hi all-

    I have tried to downgrade from 4.2.1 to 3.2.2 at least 10 times but no joy. iPad came w/3.2.2, I saved the blob w/ Tinyumbrella, upgraded to 4.2, then to 4.2.1. Now trying to downgrade back to 3.2.2. I have the 7B500 firmware saved on my desktop, I run Tinyumbrella in admin mode, it says it has the 7B500 blob (as well as 8C148 and 8C5115c) for this device, I put the iPad in DFU mode, it detects properly, I run shift-restore, and it says "The iPad "iPad" could not be restored because the firmware file is not compatible." No error number is given.

    I will be forever in your debt if you can help me figure out what is wrong.

    I forgot to say that no, Skype is not running, and yes, TSS server is running. Thanks.

    Step 1: Download old ipsw firmware files iPad iOS 3.2.2 or 3.2.1 and save it on your desktop.

    Step 2: Put your device into DFU mode with following instructions.

    * Connect your iPhone to your computer.
    * Turn iPhone off.
    * Hold power and home together for 10 seconds (exactly).
    * Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
    * A few seconds later iTunes should detect your iPhone.
    * If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.

    Step 3: Do the following changes in your server.“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 “74.208.105.171 gs.apple.com” useful to redirect requests for certificates for authenticity that iTunes will make to the Saurik server.Follow the steps to do so.

    For windows users:

    # 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: 74.208.105.171 gs.apple.com

    For Mac users:

    # Navigate to Go -> Go to Folder and enter the path /etc
    # Open the file hosts with TextEdit, add the following string 74.208.105.171 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.



    That’s all.
