Preparations for Jailbreaking iOS on Windows
Preparations needed for jailbreaking iOS devices on Windows:
Iphone 4 Jailbreak Tools
- Windows 7 or later, 32 or 64 bit
- USB flash drive with 2 GB, or more, capacity
- Download ubuntu-20.04.1-desktop-amd64.iso

Detailed Steps for Jailbreaking iOS on Windows
# Create Ubuntu USB Flash Drive
Step 1.Insert your USB flash drive.
Step 2.Download the executable Rufus and run it – no installation is necessary. Once downloaded, the application is ready to use.
Step 3.Click the 'Select' button and find the Ubuntu image you've downloaded. After selecting, the 'ubuntu-20.04.1-desktop-amd64.iso' file will appear in the boot selection. Keep the other options default and click 'Start'.
Step 4.Rufus will show a warning that all data on your live USB will be destroyed. Please backup your USB files if necessary and then click 'OK'. Once an ISOHybrid image is detected, select the recommended option and click 'OK'.
Wait for 2 to 3 minutes when Rufus is creating USB flash drive of Ubuntu.
Click 'Close' when the process completes.
Note
Please re-plugin the USB flash after creating Ubuntu drive in case that it becomes unrecognized.
# Boot Ubuntu on Windows
Step 5.Go to 'Windows' > 'Restart' to restart your compuer.
Press the F12 shortcut key when the computer is turned on and before the operating system loading. Here my computer is Dell.
Note
For most computer brands, the keyboard shortcut for launching BIOS is F12. If F12 does not work, you need to search for the correct key that matches your brand.
The BIOS control window of your computer will appear. On the BIOS window, you need to choose the Ubuntu USB flash drive you've just created. Use the arrow keys on your keyboard to select the correct option, and then press 'Enter'.
Step 6.You'll see the Ubuntu system loading as below. All Ubuntu filesystem checks are in progress.
Select the first option '*Ubuntu' to boot the selected Ubuntu OS.
Step 7.When the booting ends, select 'Try Ubuntu' to start Ubuntu from the flash drive.
Now you've entered the Ubuntu system. Keep your iPhone/iPad/iPod touch connected to the computer and you'll see it on the desktop.
# Jailbreak iOS Device
Step 8.Find the 'checkra1n-x86_64' jailbreak tool file you've downloaded before. If you haven't downloaded the file before restarting the computer, you can download it now through a browser. To open Checkra1n jailbreak tool, you'll need to use Terminal.
Open Terminal, enter codes in Terminal in succession (you can copy the codes in the quotations directly):
- enter 'chmod +x ' (there is a space before the plus sign and a space after the x) and drag the 'checkra1n-x86_64' file to the Terminal window and press 'Enter' key.
- enter 'sudo ' (there is a space after sudo) and drag the 'checkra1n-x86_64' file to the Terminal window again, then press the 'Enter' key.
Note
If the Checkra1n file can't be draged to Terminal, please copy and paste it to the desktop. Right click the file and choose 'Show in Files' and then drag it again.
Jailbreak My Iphone 4
If the codes are correctly entered in the previous step, then Checkra1n will be running with the following screen appear:
#What to Do when the 'Start' button of Checkra1n is grey?
If your device is running versions that have not been tested by Checkra1n, especially iOS 13.5.1 and 13.6, the 'Start'button on Checkra1n will be grey. You need to click 'Options' and select 'Allow untested iOS/iPadOS/tvOS versions' and click 'Back' then the 'Start' button will be usable.
Step 9.To jailbreak your iOS device, Checkra1n requires your device to be in recovery mode.
Click 'Next' and Checkra1n will help your iOS device enter recovery mode automatically.
Click 'Start' and follow the given instructions on Checkra1n to put your iOS device into DFU mode.
After entering DFU mode successfully, Checkra1n will immediately start installing jailbreak. Clik 'Done' when the jailbreaking process completes.
#What to Do when Jailbreaking Gets Stuck on 'Right before trigger'?
If Chcekra1n gets stuck on 'Right before trigger (this is the real bug setup)' screen, try the following solutions to fix this:
- use another USB and repeat the tutorial steps
- flash your iOS device and restart the computer to try again
Note
If the jailbreak fails, please plug your device into the USB port on the back of the computer mainframe and try the jailbreak process again. Usually the USB port on the back of the computer mainframe is 2.0 which has better compatibility then the 3.0 version in the front.
Step 10.After successful jailbreaking, quit Ubuntu and restart your computer. Go to the top right corner, click 'Power' > 'Power Off' > 'Restart'.
Manually unplug your USB flash from your computer's USB port and then press 'Enter'.
After restarting, your computer will automatically enter Windows operating system. Launch iBypasser Windows version, and click 'Start Bypass' to finish bypassing the iCloud activation lock screen.
Q: What is checkra1n?
A: checkra1n is a community project to provide a high-quality semi-tethered jailbreak to all, based on the ‘checkm8’ bootrom exploit.
Q: How does it work?
A: Magic hax.
Q: Why was the beta release delayed?
A: We didn't want the release quality to end up like iOS 13.2, you deserve better.
Q: wen eta?
A: bruh we're past that.
Q: How do I use it?
A: Open the checkra1n app, and follow the instructions to put your device into DFU mode. Hax happens auto-magically from that point and the device will boot into jailbroken mode. If you reboot the device without checkra1n, it will revert to stock iOS, and you will not be able to use any 3rd party software installed until you enter DFU and checkra1n the device again.
Q: Ugh, I don't like GUI?
A: Ok, you can use './checkra1n.app/Contents/MacOS/checkra1n -c' from the console, or download a Linux CLI build.
Q: Is it safe to jailbreak? Can it harm my device / wipe my data?
A: We believe jailbreaking is safe and take precautions to avoid data loss. However, as with any software, bugs can happen and *no warranty is provided*. We do recommend you backup your device before running checkra1n.
Q: I have a problem or issue to report after jailbreaking.
A: Many problems and bootloops can be caused by buggy or incompatible tweaks. Remember many tweaks never saw iOS 13 in the pre-checkra1n era. If you suspect a recently installed tweak, you may attempt to enter no-substrate mode by holding vol-up during boot (starting with Apple logo until boot completes). If the issue goes away, a bad tweak is very likely the culprit, and you should contact the tweak developers.
Q: I have a problem or issue to report and I don't think it's related to a bad tweak.
A: Please check here and follow the bug report template.
Q: I lost my passcode. Can checkra1n decrypt my data or get access to a locked device?
A: No.
Jailbreak Iphone 4 Ios 7
Q: Can I ssh into my device?
A: Yes! An SSH server is deployed on port 44 on localhost only. You can expose it on your local machine using iproxy via USB.
Q: I love the project! Can I donate?
A: Thanks, we love it too! The project does not currently take any donations. If anyone asks for donations, it's a scam.
Jailbreak Iphone 4 Mac Os X
Q: Where are the sources? I want to write a dark-mode theme and publish the jailbreak as my own.
A: checkra1n is released in binary form only at this stage. We plan to open-source later in 2020.
Q: When is Windows support coming?
A: We need to write a kernel driver to support Windows (which is a very complex piece of code!) which will take time. Rest assured however, we are working hard on it.
