This is because newer iOS devices have a built-in protection mechanism that blocks you from downgrading the device. This design exists to prevent users from jailbreaking. When a new iOS version comes out, some people accidentally tap update&hellip; Usually the latest iOS version cannot be jailbroken, so users who have updated can only downgrade in order to jailbreak. This is when a big problem appears: you cannot downgrade&hellip;&hellip; The TinyUmbrella introduced today is software that can help you downgrade successfully. It can back up something called SHSH for you. Once you have backed up the SHSH, you can downgrade successfully~</p> <h2>https://coder.tw/en/posts/jailbreak-ios4-on-iphone-browser/Thu, 05 Aug 2010 01:25:49 +0000https://coder.tw/en/posts/jailbreak-ios4-on-iphone-browser/<p style="text-align: center;"><a href="https://pub-6c026d2742d14927bfa2d850c31eac91.r2.dev/wp-content/uploads/2010/08/jb.png"><img class="size-full wp-image-3657 aligncenter" title="jb" src="https://pub-6c026d2742d14927bfa2d850c31eac91.r2.dev/wp-content/uploads/2010/08/jb.png" alt="" width="224" height="336" /></a></p> No joke, this time it's a real one-click jailbreak. From start to finish, you only need to press one button to complete the jailbreak. You don't even need to download any jailbreak program. All you have to do is open a web page on your iPhone or iPod Touch. It's really amazing. When I saw the news this morning about this magical jailbreak method, I didn't believe it. But just now I tested it on my own iPod Touch (sweating nervously the whole time...), and the result is real!! However, this web-based jailbreak method <strong>currently only works on iOS 4</strong>, and it may stop working very soon. Also, don't worry that this web jailbreak program will sneak a Trojan horse onto your iPhone. I had that concern too at first, but then I saw that it's a product of the famous iPhone Dev Team, so I felt better~
