I've been searching around for a a while now and So far I haven't found any full jailbreaks for ios 11.4 on a 6s. To be honest, I am new to the jailbreaking scene. I've installed Velonzy, but could find no jailbreaking tools. Am I missing something, or is there truly nothing left.
PS. I would downgrade to a system-rootable version but I haven't any SHSH blobs, or found any alternative method. Is it possible?
