Download Checkra1n For Windows Ios 12.5.5 Direct
The first and most critical fact: The official checkra1n tool is only available for macOS and Linux. The development team has not released a native Windows application.
However, Windows users are not completely locked out. You can still run checkra1n on Windows using one of two reliable methods:
This guide focuses on the Bootable Linux USB method, as it is free, safe, and widely used by the jailbreak community.
Let’s get straight to the point: There is no official, stable version of checkra1n for Windows.
Despite years of development and promises, the checkra1n team has not released a native Windows executable (.exe) that works reliably. While the tool is natively available for macOS and Linux, Windows support was stuck in "beta" or "coming soon" limbo for years and was never fully realized by the core development team.
Warning: If you search the internet and find websites claiming to offer "checkra1n.exe for Windows," proceed with extreme caution. These are often:

Checkra1n is a community-favorite jailbreak tool because it relies on a hardware vulnerability that Apple cannot patch with software updates. If you are looking to download checkra1n for Windows to jailbreak iOS 12.5.5, it is important to understand that a native Windows ".exe" file for this tool does not officially exist. However, you can easily run it on a Windows PC using a bootable USB drive.
This guide will walk you through the process of setting up and using checkra1n on your Windows machine to unlock your iOS 12.5.5 device. The Reality of Checkra1n on Windows
The checkra1n jailbreak is built on the "checkm8" exploit. This exploit requires specific low-level access to USB controllers that Windows handles differently than macOS or Linux. Because of these technical hurdles, the developers have not released a direct Windows installer.
To get around this, Windows users utilize checkn1x or Odysseyn1x. These are lightweight, Linux-based "Live" environments that fit on a USB drive. You boot your computer from the USB, run the jailbreak, and then restart back into Windows. It is safe, fast, and does not affect your Windows files. Prerequisites Before You Start
Before attempting the jailbreak, ensure you have the following items ready: A Windows PC: Any standard laptop or desktop will work. A USB Flash Drive: At least 256MB of space is required.
A Compatible Device: Checkra1n supports A7 through A11 chips. For iOS 12.5.5, this typically includes: iPhone 5s, iPhone 6, and iPhone 6 Plus. iPad Air, iPad Mini 2, and iPad Mini 3. iPod Touch 6G.
A MFi Certified Cable: Avoid using USB-C to Lightning cables; standard USB-A to Lightning cables are much more reliable for DFU mode. Step 1: Download the Necessary Files You will need two specific files to make this work:
The ISO Image: Download the latest version of checkn1x (this is the most stable version of checkra1n for bootable USBs).
The Flashing Tool: Download Rufus or BalenaEtcher. These programs allow you to "burn" the ISO image onto your USB drive so it becomes bootable. Step 2: Create the Bootable USB Plug your USB drive into your Windows PC. Open Rufus. Under Device, select your USB drive.
Under Boot selection, click "Select" and choose the checkn1x ISO file you downloaded.
Click Start. This will erase everything on the USB drive, so make sure you don't have important files on it. Once the process is "Ready," close Rufus. Step 3: Booting into Checkra1n Keep the USB plugged in and restart your computer.
As the computer starts, repeatedly tap your Boot Menu Key. This is usually F12, F11, Esc, or F10 depending on your motherboard brand (e.g., Dell is F12, HP is F9 or Esc). Select your USB Flash Drive from the list of boot options.
Your PC will now load a simple terminal interface. Within seconds, the checkra1n GUI will appear on your screen. Step 4: Jailbreaking iOS 12.5.5 Connect your iPhone or iPad to the computer.
If checkra1n says your device is not supported, go to Options and check the box for "Allow untested iOS/iPadOS/tvOS versions." (Note: Since iOS 12.5.5 is older, checkra1n usually recognizes it immediately). This guide focuses on the Bootable Linux USB
Click Start. The tool will ask to put your device into Recovery Mode. Click Next.
Follow the on-screen instructions to manually put your device into DFU Mode. This usually involves holding the Power and Home buttons in a specific sequence.
Once the device enters DFU mode, the exploit will run. You will see a "verbose" boot (code scrolling on your iPhone screen). When the tool says "All Done," your device will reboot. Step 5: Finalizing the Process
Unplug your device and restart your PC to go back to Windows.
On your iPhone/iPad, you should now see a new app icon called checkra1n. Open the app (ensure you are connected to Wi-Fi). Tap on Cydia and select Install. Once Cydia is installed, you are officially jailbroken! Important Safety Reminders
Semi-Tethered Status: Checkra1n is a semi-tethered jailbreak. If your device dies or you restart it, the jailbreak will disappear. You will need to plug it back into your USB boot drive to re-enable it.
Passcode/TouchID: For A11 devices (iPhone 8/X) on iOS 14+, you must disable the passcode. However, for iOS 12.5.5 on older devices, you can keep your passcode and TouchID active without issues.
Backup Your Data: Always perform an iCloud or iTunes backup before jailbreaking. While checkra1n is very stable, it is always better to be safe. Have you ever used a bootable USB before?
Are you getting any specific error codes (like Error -20 or Error -31)?
I can provide troubleshooting steps tailored to your hardware.
While no official checkra1n application exists for Windows, users can jailbreak iOS 12.5.5 by utilizing Linux-based USB boot tools like Checkn1x, or through third-party Windows ports such as iRemovalRa1n or Winra1n. These tools leverage the checkm8 exploit for A7-A11 devices, requiring a re-application of the exploit if the device restarts. For the official tool download, visit
