Here's a quick guide on how to take an iOS 9.3 app and make it run on iOS 9.0.2 .
This should work for other similar situations as well (like 8.4 app on 8.3) but should not be used to run apps between major iOS revisions ( iOS 9 to iOS 8 )
You will need iTunes and an archive program (like WinZip or WinRAR)
- Download your app with iTunes (or from AppCake) to your computer
- Go to your app download folder (..\My Documents\My Music\iTunes\iTunes Media\Mobile Applications)
- Open the IPA file of your app (right-click and Open With the archive program)
- In the archive, go to Payload -> (appname).app
- Extract the file "Info.plist"
- Open the file in Notepad or a simple text editor
You need to edit a line...
Replace the numbers at #.# with the iOS version you want to use the app with
You can also edit these following lines the same way, although the above should be all you need
<key>DTPlatformVersion</key> <string>#.#</string> <key>DTSDKName</key> <string>iphoneos#.#</string>"
7. Save the file
8. Drag the file back into the archive and overwrite the existing file
9. Save the archive
You should now be able to install the app on your device using iTunes. Or import it with AppCake and install it that way. If not, you can use a program like iFunBox.
I like to rename the IPA file so I know it's been modified. Good luck! Please share your results
Don't post modified IPA files without labeling them as such! (i.e. SampleTank.ModifiedForiOS9.IPA)
