Apple Stops Signing iOS 11.3, Downgrades and Restores No Longer Possible

Apple has stopped signing iOS 11.3 on Wednesday, a move that prevents iPhone and iPad users from downgrading or restoring to this particular version of iOS through iTunes .The Cupertino-based company regularly stops signing older iOS versions just a couple of weeks after releasing a new software update. Given how Apple just released iOS 11.3.1 a little more than a week ago, this news shouldn’t come as much of a surprise.

Typically, it's advised that users looking to jailbreak remain on the lowest firmware possible; however, we do know that iOS 11.3.1 can be jailbroken. A jailbreak of that firmware was demonstrated at InfiltrateCon by Tencent Keen Security Lab. Unfortunately, we don't expect the Keen team to release their jailbreak to the public. The most recent jailbreak release works on iOS 11 - iOS 11.1.2.
