Hi, I am sorry, been googling but all answers point towards OTA (tutu, vshare, etc)..
I usually download apps from this site, then install them by ifunbox & itools. All always worked on 5s iOS 9.3.1, iPad 2 iOS 8.1, iPad Air1 iOS 7.1
However, recently I got iPad Pro1 (10.3.3) jailbroken with doubleh3lix, cydia is good, tweaks work perfectly... but could not install downloaded apps by ifunbox or itools.
I read that you can install with cydia impactor, have not tried it, but is that the only way to install ipa downloaded on this site on iPad Pro1 on iOS 10.3.3 ?
I really need root access too, waiting for Filzaescape working on 10.3.3 .....
Thank you for all your replies
