QUOTE(huiqing88 @ Jan 9 2011, 11:33 PM) Because Apple had stopped signing older firmware. So now you can only officially restore your iOS to the latest version. ohh i see..sure that must be a way to restore back. can you explain about SHSH blob. i dont understand thatDowngrade is not possible if no SHSH blob saved. You need extra software such as TinyUmbrella to help you kick out of recovery mode.  right now im trying to restore to newest ios4.1 |
