Have you heard about Rooting ? For Android User Rooting is the way of accessing the additional
feature that normally is restricted by the smartphone. Beyond the basic activity if you wish to use it then you can go for rooting. It gives you the superuser privilege on your smartphone. Rooting is basically the mode of operation which you have to run at your own risk but after rooting you will be able to tweak your smartphone in your own way.
The iPhone has its own way to access that privilege and is known as jail break. There are a lot of ways mentioned over the internet with or without PC. In my experience I do believe without a pc it is not possible or not a very reliable way to do it. To make it happen you need either Mac or Windows. If you are interested to know how it is done then you are in the right place. Let me tell you If you are using Linux then the iphone is not compatible with you at all. Linux users are used to the freedom but even after the jailbreak that thirst can not be fulfilled by the iphone because the iphone is considered as the best security device and it contains a lot of restrictions. In case of reverse process after jailbreak you must have the Windows or Mac so make sure you do each step with full precaution. This lesson is the process of jailbreak using the checkrain and is compatible with Linux and MacOs.
For the Windows platform 3utools and TinyUmbrella can be used. Apart from it. You can jailbreak iphones using Animate, iSHSHit, unc0ver as well.
For Jailbreak you need to visit for Checkrain--> checkra1n visit the URL https://checkra.in
--> Download the latest checkra1n version release
$ echo 'deb https://assets.checkra.in/debian /' | sudo tee /etc/apt/sources.list.d/checkra1n.list
$ sudo apt-key adv --fetch-keys https://assets.checkra.in/debian/archive.key
$ sudo apt-get update
$ sudo apt-get install checkra1n
After the installation process is done then open Terminal in superuser mode.
$ sudo checkra1n
--> Enter your password
After you connect the USB and itunes logo will appear.
--> As the phone comes in the Recovery mode step then press start on the checkra1n.
Congratulations on your successful jailbreak.
After the installation process is done then open Terminal in superuser mode.
$ sudo checkra1n
--> Enter your password
when the checkra1n is open connect your iphone using USB and press on start. If it doesn't start you just need to press your iphone keys.
** POWER BUTTON+HOME BUTTON** After you connect the USB and itunes logo will appear.
--> As the phone comes in the Recovery mode step then press start on the checkra1n.
Then your phone goes on the recovery mode and after boot you will get your iphone jailbroken. Next you see your menu then you will find the checkra1n app installed. Open it and install the cydia. Let me tell you that Cydia is the app store which lets you install a lot of apps which are not listed or available on the app store.
Congratulations on your successful jailbreak.
