Help/Support Installing Older Apps

[TomLiya 2 iPad Pro (M1, 11") iOS 15]

Hello, 

I have a questions, how can I install older Applications using the Plus App? For example I want to install ‘Gangstar Rio City of Saints'. To which iOS Version should I change it? I'll use custom install.

 

Thanks for the Help

Hello,

It’s minimum iOS version so just set it to 7.0

This does not guarantee it will work, though.

Sadly it didn’t work. I got this error: This app cannot be installed because
its integrity could not be verified.
