[New] Checkra1n iCloud Bypass | Free Untethered Windows/Mac

Are you looking for a tool that can overcome the iCloud Activation Lock and give you access to all of your iPhone’s features?

Checkra1n iCloud Bypass could be exactly what you’re looking for. This is a tool that, like many others, provides an effective solution to getting past the iCloud lock security feature.

Better yet, it’s a free tool that you can find and use very easily.

So, in this article, we’ll be discussing how this tool works and we’ll also introduce some alternatives you can use.

Part 1. How Does Checkra1n iCloud Bypass Work?

1. What is Checkra1n?

Checkra1n is classified as an iCloud bypass tool meaning that it is capable of iCloud Activation Lock removal and establishing full access to features like iMessage and FaceTime.


For iCloud bypass with Checkra1n to be successful, it uses a jailbreaking technique.

What is jailbreaking?

When you jailbreak your iPhone, you remove the iOS firmware restrictions that would usually limit your actions. For instance, after jailbreaking, you will be able to install apps that Apple typically don’t allow on the App Store.

In the same way, jailbreaking allows Checkra1n to bypass a core iCloud security feature and return access to the user.

2. Requirements Before Using Checkra1n

Before we jump into the installation and usage of Checkra1n iCloud Bypass, make sure you meet these requirements so that you can use the tool.

  • You must have access to a Mac computer (no Windows version is available)
  • The most recent iTunes version must be downloaded
  • iOS 12.3 or later must be installed on your iPhone or iOS device
  • Your device must be an iPhone 5S to iPhone X (newer devices aren’t supported)

As long as you have a relatively new iPhone (but not newer than the iPhone X) and keep the iOS updated, there’s no reason for this method not to work.

3. Limits of Checkra1n iCloud Bypass

As you can tell from the list of requirements, there are a few limitations of Checkra1n that are worth mentioning:

  • The most recent iPhone models are unsupported – only support iPhone 5s – iPhone X
  • Older iPhones that run earlier versions of iOS are not compatible – only support iOS 12.3 and above
  • Certain iPods and iPads are not compatible either
  • Jailbreaking your iOS device is required and may cause damage
  • After bypassing, these functions won’t work:
    • SIM signal
    • iMessage
    • Facetime
    • Not able to add new iCloud account
    • Not able to use iTunes (it will show device activation screen)

While most people will discover that Checkra1n is effective, if you fall outside of these limitations then you won’t be able to use it.

4. What to Know Before Jailbreaking iPhone

Before we walk you through our method to jailbreak iPhone on Windows without Ubuntu, there are a few notes that you should keep in mind:

  • Jailbreaking your iPhone will likely breach your warranty if you have a contract/data plan
  • Since jailbreaking involves installing a modified version of the iOS firmware, back up your data beforehand or it will be wiped
  • Jailbreaking tools are specific for each iOS version, so if an iOS update is released you will have to jailbreak your iPhone again
  • Only use reputable jailbreaking tools otherwise there is a risk that you will download malware
  • No matter what, there will always be a risk of bricking your iPhone when you jailbreak it

So, while you will get to reap the benefits of having fewer limitations on your iPhone, you should be aware of these risks too.

Part 2. How to Use Checkra1n for iCloud Bypass

Now for the important part: how to use Checkra1n iCloud Bypass. We’ll be showing you two methods, how to use it on a Mac computer as well as a Windows computer.

1. On Mac

Starting with the Mac method, this is as straightforward as possible.

There are a couple of technical aspects to this method but as long as you stick to our steps, you’ll have no issues setting up Checkra1n.

Step 1. Start by downloading the official Checkra1n tool.

Step 2. Install two other components, brew and usbmuxd, by entering these commands into the Terminal app:

/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install…)”

brew install usbmuxd

Step 3. After those finish installing, launch Checkra1n.

Step 4. Next, connect your iPhone to your computer and follow the instructions to jailbreak the iPhone.

Step 5. Use usbmuxd’s built-in iProxy tool to create a tunnel from Port 2222 to Port 44 (or Port 22 if this fails) with the following command:

iproxy 2222 44

Step 6. Press Command + T to launch a new Terminal window and enter the command:

ssh root@localhost -p 2222

Step 7. Enter the following commands to patch the system’s setup file and move its location:

mount -o rw,union,update /

mv /Applications/Setup.app /Applications/Setup.bak

rm -rf /Applications/Setup.app

Step 8. Lastly, enter these two commands to clear the setup file’s cache and end any springboard processes:

uicache -all

Killall backboardd

After you enter the last command, you’ll have bypassed the iCloud Activation Lock using Checkra1n.

Many people will be uncomfortable using the Terminal app and entering a lot of commands they’re unfamiliar with, but as long as you copy exactly what we’ve shown you there will be no problems.

2. On Windows 10

We previously mentioned that there was no version available for iCloud bypass with Checkra1n and this is still correct.

However, there is a different (and more advanced) approach that lets you use Checkra1n iCloud bypass on a Windows computer.

Step 1. Download 3 things: Sliver, UNetbootin, and the Ubuntu ISO.

Step 2. Launch UNetbootin and open the Ubuntu file that you downloaded.

Step 3. Once the Ubuntu ISO is installed you must restart your PC. Then, when your PC turns back on, you can boot into UNetbootin and this will load your computer in Linux.

(Checkra1n is only available for Mac & Linux system, this is why we install Ubuntu to boot your computer into the Linux OS.)

Step 4. After Ubuntu has set up, connect to the internet and download the Linux version of Checkra1n.

Step 5. At the bottom left corner of the screen, clicking on the Show Applications button. Launch the Terminal app then enter the following command:

chmod + X <Checkra1n file path>

Step 6. Then drop the Checkra1n in the front of the command and press enter.

Step 7. Enter the following command and drop Checkra1n in the front of the command.

sudo <Checkra1n file path>

Step 8. Next, connect your iPhone to computer. Then launch Checkra1n and follow the instructions that it gives you to jailbreak your iPhone.

Step 9. Once the jailbreak completes, restart your computer and boot it into Windows OS.

Step 10. Then launch Sliver (Checkra1n icloud bypass activator) and click on Connect to iTunes > Continue, then your iPhone should be unlocked now!

This is obviously a lot more complicated than if you had a Mac computer.

But it is still a suitable approach nonetheless and we’d recommend giving this a shot if you’re a Windows user before trying any alternatives.
