A renowned iOS Hacker Luca Todesco, who is known for the first person to jailbreak a new version of iOS but then he decides not to release it for public. This time Todesco has done something quite unusual and he have released a Safari based web tool which allows you to re-activate the Pangue Semi-Untethered jailbreak of iOS 9.3.3 on your devices. So, instead of the Pangu app, you can reactivate the Semi-Untethered jailbreak by just using the web app.
Okay, so now you might be thinking that what is semi-untethered jailbreak? Basically, there were tethered jailbreak before it and they stopped working after the device rebooted and the users had to connect their iPhone/iPad to their computer and launch the tool and do all the process from start to make it jailbroken and functional again. The semi-untethered jailbreak of iOS 9 was released by Chinese company PanGu and they made things a little bit easier. So, when the device reboots then instead of connecting to PC, they had to install an app and jailbreak it from there so, their device becomes jailbroken again. The solution wasn’t solved to full and hackers called it semi-tethered.
This web tool only works for iOS 9.3.x already jailbroken devices and this tool won’t jailbreak your device from start. So, if your 9.3.x iOS device(64-bit only) is not jailbroken then you can’t use this tool before you jailbreak it with the help of PanGu tool. With the help of this tool, you can reactivate the PanGu jailbreak when your device reboot.
The tool is helpful and you don’t need to install the Pangu’s Semi-untethered app. So, now instead of launching the app and waiting you can just use this web tool. This web tool has another benefit that it works without certificate restrictions.
So, if your iOS 9.3.x device is jailbroken using the PanGu jailbreak tool then visit this page on your jailbroken iOS device and then tap on Go button to semi-untether it when it stops working after your device rebooted. As said by Todesco, this tool may not work in a single try. So, you might have to try this tool multiple times.
