Untether Your Tethered Jailbreak With Rocky Racoon
“Please do *not* try to “reset all device and settings” if you’re already tethered JB! In which case you should be installing it via Cydia)”
What that means is that you can download the underlying jailbreak mechanic directly off Cydia if you need, untethering what you already have set up. That tweak is called “Rocky Racoon” [sic], and it’ll take your tethered jailbreak, and cut the cord — and you can just grab it from the Telesphoreo repository.
However, once this is done, keep in mind that if you uninstall Rocky Racoon, you’ll lose the untether.
