3uTool is the all-in-one tool for iOS devices, we can jailbreak the device directly from 3utools, or either we can create the USB bootable checkra1n from 3utools.

  • Jailbreaking with checkra1n USB flash boot
  • Install the AFC binary.

2.) After the USB flashing reboot or shut down your system and go to your boot options menu. As I am using an Acer laptop so most of the time the key is F12 but you need to sure the key is enabled from bios. And then select the USB flash drive for boot. As show below screenshots.


To check the boot option menu key you can go to your system bios and find the boot menu option which indicate your key.
