@AtomBombed To ssh into a jailbroken device, you need install the OpenSSH server on the device first (via Cydia). Then you can ssh to the device from an iOS ssh app installed on the same device. I used to do that on earlier version of iOS. Many ssh apps are available. The one I used is called iSSH but has since demised. But there are many other, e.g. Serverauditor, Prompt2.

You can even ssh to it using just StaSh. The latest 0.6.3 version has a proper terminal emulation for ssh. So from stash, you can do

ssh --password SECRET root@localhost

If you haven't changed the password, the default password is alpine.
