How to Jailbreak iPhone 7 (iOS 13.5.1) using Ubuntu Linux and checkra1n

Creating a bootable flash drive

Warning: You can't Jailbreak using Oracle VMBox (primarily because it doesn't support USB connections, however if you can bypass that, then maybe yes, you can) but it's not really worth the hassle. The way I did it was by creating a bootable flash drive with Ubuntu and then Jailbreaking using checkra1n.

Steps:

First things first, let's set up the flash drive.

1. Download Ubuntu ISOs from [https://ubuntu.com/download/desktop]. I used Ubuntu 20.10.
   
2. Download Rufus [https://rufus.ie/].
3. Set it up! I didn't put any persistence in, but you can, depending if you do this a lot.

Boot up: 

I use an MSI GS-65 Stealth, which is a classic beauty, and so I spam F11 as soon as the MSI logo comes up. And then choose the flash drive to boot from. If this doesn't work for you, you may want to change the boot order of your device. For me it's spamming Del as soon as the MSI logo comes up. 

You don't have to install Ubuntu. Click on "Try Ubuntu", we're trying to save some sweet time.

Flex your terminal skillz:

Hurray, fire up the terminal (press

Ctrl + Alt + T

). And let's follow these steps by Reddit user

the link to the original article can be accessed here.

Run these commands line by line:

echo "deb https://assets.checkra.in/debian /" | sudo tee -a /etc/apt/sources.list
sudo apt-key adv --fetch-keys https://assets.checkra.in/debian/archive.key
sudo apt update
sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe"
sudo apt-get update
sudo apt-get install libncurses5-dev
sudo apt-get install libirecovery3
sudo apt-get install checkra1n

Now, go to checkra1n's official website (please be-ware of phishing sites) https://checkra.in/releases/#all-downloads and click on "Download for Linux (CLI, x86_64)". At the time of writing this, Checkra1n's version is 0.11.0 beta. Go to your Downloads folder, right click checkra1n > Properties ... and copy it's path. 

Get back to terminal and enter this (obviously change it according to your path):

echo "deb https://assets.checkra.in/debian /" | sudo tee -a /etc/apt/sources.list
chmod a+rwx /home/ubuntu/Downloads/checkra1n

However, after executing the last command it won't throw up anything, which means we're good.

Running checkra1n using terminal (not recommended)

Oh, you're such a brave heart, aren't you? Enter the following in the terminal:

cd Downloads
sudo ./checkra1n

Running checkra1n using GUI (recommended)

For me, the Jailbreak got stuck on "right before trigger". That was maybe because I hadn't installed

libirecovery3

, but I switched to the GUI anyway, it seemed sleeker to me. 

 

 Plug in your iPhone and checkra1n will guide you through the rest of the steps.

Common errors (a.k.a. headaches):

• checkra1n stuck at right before trigger: Have you installed the dependencies correctly? If not,

  sudo apt-get remove checkra1n
  sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe"
  sudo apt-get install libncurses5-dev
  sudo apt-get install libirecovery3
  sudo apt-get update
  sudo apt-get-upgrade
  sudo apt-get install checkra1n
  

• checkra1n entering DFU fails: Remove passcode from iPhone, change USB port, use checkra1n GUI. To get iPhone out of GUI hold down power button and volume down button simultaneously till Apple logo appears on screen.

Jailbreak headaches:

Some apps like Google Pay, PhonePe, and other UPI apps etc. aren't supported on Jailbroken devices. To bypass jailbreak detection, go to Cydia > Sources > Edit > Add. Then add

https://ryleyangus.com/repo/

as a source. Find and install Liberty Lite and then enable the apps in the settings for which you want the Jailbreak detection by-passed.
