Help/Support New just need help

[ItsNickTheCat 0 iPhone 5s 11.1.2]

Hello everyone my name is Nicholas and I am new to this site since today. I have had a whole lot of questions. I wanted to ask If someone can help me jailbreak my device because this is a prepaid phone and pretty much is an old device . Its an IPhone 5s and its running on 11.1.2 and I am wondering If someone can help me jailbreak it. Many people have told me to downgrade my device but I have no clue what to do. So, I am new to jailbreaking and cydia and everything else just wanna know how to get it on my device and how to jailbreak my device.

You can't jailbreak since you are on iOS 11. You can't downgrade neither. sorry
