What is jailbreak?
Jailbreak means removing all those restrictions imposed by the Operating System i.e. iOS. Though we do not recommend you to do jailbreaking to your device but just in case you want to do some tweaks on your device but iOS does not allow, jailbreaking is the way.
Currently, the iOS 10.1.1 jailbreak is in beta version and only supports iPhone 6S, iPhone 7 and iPad Pro. Further, when the full and stable version will be launched, it will also support all 64-bit smartphones (excluding iPhone 5 and iPhone 5C).
Semitethered jailbreak means if you turn your device off and if the battery dies during the process, the Cydia app will only open and crash once you restart your phone.
(Note: We again bring it to your attention that don’t jailbreak through this method unless you are a developer. We don’t recommend jailbreaking at all.)
Plug in your device and make sure that iTunes is not running on your desktop.
Go to cydiaimpactor.com and download the Cydia Impactor from one of the mirrors available on the website.
Download the jailbreak file from https://yalu.qwertyoruiop.com/.
Drag the downloaded file into the Cydia Impactor.
It will then ask for your Apple ID. Login here with your Apple ID and password.
Jailbreaking has started. In a minute or two, you will see an application having an icon as plain texture with gridlines.
After it has been done, open this app like any other sideloaded app.
Go to Settings>General>Profile, tap on your Apple ID and touch Trust.
Open the application. All you will see is just a blank screen and then the app will crash. Restart your phone and repeat this step again and again till Cydia pops up.
Since it is in beta version, no useful tweaks can be installed. So, in case you have not done it till now, do wait till the final release. It even crashes at times but the developers have guaranteed that it will work perfectly after the release of full and stable version.
