LycaJB is a project that aims to fill the gap in iOS 11.0 - 11.3.1 jailbreaks. While this jailbreak is specifically aimed at developers it could be turned into a public stable jailbreak which includes Cydia. Right now we had to make the hard decision to remove Cydia from LycaJB as it caused our test devices to bootloop. We are working hard to make this stable and ready for the public.

Root ShellsYou can now use SSH on iOS, ssh root@ip, password alpine

nc IP 4141
It won't show that it is connected, but once it goes to a new line wait 5 seconds and type ls

ssh root@IP password: alpine
Just like normal SSH except you may need to run /var/profile if it doesn't show your device name.

ssh root@IP -p 2222
Yeah um, this one barely works. It works like 5% of the time. Sorry.
