I Managed To Downgrade My iPad Air (1st Gen) To iOS 10.3.3 With LeetDown. I Backed Up An IPA File For A Discontinued App: Buddyman: Kick 2. I Installed It, Jailbroke The iPad, And Gave Myself Unlimited Money By Editing The Game's .plist File With Filza! (Installed From Cydia, No Repo Needed.) So, Here's Footage Of The Game Running In 2020!

(ONLY Works With iPads On iOS 10 Or Older, Use It On iOS 11 Or Newer Will Not Work.)
IF You Get The Apple ID Password Screen On Launch, I Don't Know How To Fix it, So Try Googling A Way To Do It With Jailbreak!
UPDATE 1|6|21: I Founs Out That The IPA Is Signed By My Dad's Apple ID And You Need To Enter Hid Password To Use It For The First Time, Sorry!
