5. run Absinthe (choose x86 or x86-64 64-bit version)
6. Click [ Jailbreak ] button
7. wait for this process is complete (will restart 1-2 times, then do not touch your device)
8 after the device interface Absinthe on the icon will appear, find and click to complete the escape. (The normal process requires WIFI link)
9. your device will reboot.
