The “Quicker” solution I found for the iPhone X 11.4 B3:
This works for me literally 100 percent of the time to jailbreak initially and re enabled the jb. No need to wait 5 minutes but yes some waiting is involved.
Note: These settings are a must for it to work: AirPlane mode = Enabled (With WiFi & BT Off) Find my iPhone = Disabled Passcode = Disabled
Optional settings: Siri - it works with it enabled and or disabled for me. Location services - again works with it enabled.
Let me know what you guys think of this method. force quitting out of the app once, seems to be the key for me!
