I have progressed slowly through my experience of the tedious ability to be able to sideload I still haven’t got a clue about SSH Cydia or code Anything other than downloading apps really but my progression has led to stuffing up my chance to jailbreak I downloaded something for my phone that made it Non-responsive I had Little choice I believe other than to restore to factory settings I did this however I thought with a back up I would go back to my iOS 11 Apple had different plans I’m sitting on 11.2.1 and I am really pissed with that if anybody can guide me get back to 11. 0  or give me some guidance whether this is possible I will reward your time as I am pretty basic  making computers moan. I would really like your help thanks

Unfortunately Apple doesn’t allow users to downgrade to iOS versions they want. Always forces you on the latest.

Thankyou Mr admin.i  Appreciate your confirmation that I may never see a jailbreak in my life time. ?? it's torngat fault, harm should have been made clearer to older ios versions  before making it public. Anyhow only my opinion, Let’s say I had a better love note from ? that they  forgot to sign and it's not as old as my current Version?  Will that work..? Is there any hope, for this j/b craved obsessed novice
