Hello! For my project i need to download many iOS Apps to analyze them later. To accomplish this task, i use the 'app-store-scr@per' for iOS. (Github: Link ) to scr@pe all needed app infos (especially the iTunes link). Then i use iTunes to automatically download all apps and i install them on my iPhone 4s (8.4, jailbroken, using scp and appinst) ... the app is installed, but when i execute it on my iphone, it only shows a login prompt and even if i type in my iTunes account and password, it just crashes.. If i download the same app (2048) directly on my iphone and execute it, it works.. what did i do wrong? Sincerly
