We know there have been many problems with installing checkra1n jailbreak for windows iOS 14.3 because of dual boot complications. So here is the new tutorial with checkra1n modra1n, previously known as ra1nusb, to install checkra1n jailbreak for windows with No Dualboot and No Mac needed.

The only thing you need to have is an empty USB (16 GB at least) to make the modra1n tool bootable. Modra1n is the updated version of Ra1nusb that supports multiple checkra1n versions, unlike ra1nusb. All the commands needed for it are given below and step by step to jailbreak your device.

This checkra1n jailbreak completely supports till A10 devices, but partially supports A11 devices where you need to skip the BRP check for your device in checkra1n jailbreak utility,

Checkra1n jailbreak is a jailbreak based on checkm8 bootrom exploit, and a blackbird exploit that lets you jailbreak your devices from iPhone 5s to iPhone X and from iOS 12 – iOS 14.3 and to the latest iOS firmware available. In this case, you can install checkra1n on iOS 13, iOS 13.4, iOS 13.7, and up as well.

What’s New in Checkra1n Jailbreak New Version

The recent checkra1n updated version supports iOS 14.3 from iOS 12; any iOS 14.3 is currently fully supported by A10 devices and partially A11 devices after skipping BRP check. This means you cannot jailbreak Apple devices that are powered by A11 – A13 devices. But don’t worry, unc0ver jailbreak has made huge progress, supporting iOS 11 – iOS 13.5 on All devices! So if you got newer devices, then here is the tutorial to that if you want to jailbreak using unc0ver. Other kernel-related issues are also fixed, which was causing the device not to boot.

As we know, checkra1n jailbreak is only available for Mac officially at the moment, but there are other ways to install checkra1n jailbreak windows, and here comes a new one that doesn’t even require a dual-boot. In the ra1nstorm tool case, you have to dual-boot on a Windows computer.

How To iOS 14.3 Checkra1n Jailbreak For Windows With Ra1nUSB/Modra1n

Step #1

1st you need to download two software, one the modra1n, and the other is to make modra1n bootable in your flash drive. So download two tools; the links are given below to download.

If Intel powers your computer, then download Intel modra1n. If AMD powers your computer, then download AMD modra1n. Then download TransMac as we’ll use this to make a modra1n bootable flash drive  (wait 10 seconds to download the free trial version to make the bootable flash drive).

Here is how to backup all tweaks and restore them later.

Step #2

When you have the modra1n dmg file, and TransMac installed, Open TransMac (wait 10 seconds to run it) and make sure you have your attached USB showing on the left side. Right-click on your flash drive name and select “restore with disk image,” and press yes.

Then you need to choose a checkra1n modra1n tool dmg file. First, your flash drive will get the format, and then the bootable process will start. Next, we’ll see how to run this bootable flash drive to jailbreak our device by running checkra1n jailbreak on a windows computer with modra1n.

Step #1

After your modra1n bootable flash drive is ready, restart your computer. Keep in mind that when you restart it, you need to enter into the computer’s boot device options for changing the boot options so that you boot from the USB, not already installed windows.

This step is essential to checkra1n jailbreak on windows. Most of the time, you enter the boot menu by pressing the F keys, f2, f12, f11, or checking on the internet for your computer’s model that how you can enter into boot menus.

Step #3

You need to select the 1st option with the title “boot macOS install from Modra1n” after selecting the 1st option. If your computer shows the moving script, that means you’re going well. But if it sticks somewhere for a long time, that means your computer is not supported for checkra1n modra1n, and you need to try it on another computer.

The official checkra1n Linux version is released as well. Here is the step-by-step checkra1n Linux jailbreak tutorial with two different methods.

Step #4

After the moving script is over, you’ll see a message asking you to attach an external mouse with your computer if your trackpad isn’t working. Attach an external mouse and click on the arrow. You’ll see the setup screen, select your language, and continue.

Installing Checkra1n on A11 Devices With Skip BRP Check

As checkra1n jailbreak is partially supported on A11 devices, you need to skip the BRP check on your device. Disable the passcode or faceID on your device, as if you want to jailbreak on A11 devices. Unfortunately, for now, you can’t have the passcode/faceID on checkra1n jailbroken devices.

If you are installing on A11 devices, on the options page, check the Skipping BRP check checkbox first. If you are jailbreaking on lower devices than A11, leave it as it is already.

Fix Checkra1n Modra1n Jailbreak Stuck And Cannot Boot Issue

Here is the solution if you cannot run modra1n on your computer, for some reason, it cannot boot or stuck. You need to add a config.plist file in bootable files in the flash drive.

Check here the checkra1n jailbreak windows bootra1n method.

First of all, download this config file, attach your flash drive to your computer and go to EFI Folder ->Clover folder. Here you’ll find a config.plist file, delete this file and add the newly downloaded config.plist file in the folder. Now try again running checkra1n modra1n jailbreak on a windows computer. You’ll see a different screen this time for booting with modra1n. It’s normal, don’t panic after seeing this.
