Many users are currently quite hyped up by the fact that they can downgrade iOS apps on their iPhone or even iPad legally and neither AppSync or a computer is required for this method.
Let’s me quickly go through the process before pointing out a small convenient in throughout the whole process. The first thing you do is go on Cydia, add UnlimApp’s repo at http://beta.unlimapps.com/, and then download App Control or App Admin.
Once your device is restarted, go to the App Store and choose any application that you want to downgrade. App Admin will then display a prompt asking you to either choose Continue to download the latest version or Downgrade to get an older version of the app.
When choosing Downgrade, App Admin will show you some known version that you can downgrade to. If you have a specific version, then that is when the process gets a bit complicated.
iPhone or iPad users who wish to download way older app’s version will need to have the softwareVersionExternalIdentifier which is basically a version for that app. You can’t find this anywhere without iFile or similar tweak.
This tutorial will show you how to do that.
Finding your softwareVersionExternalIdentifier
Step 1: Launch Cydia > Search > Type in iFile
Step 2: Install and then Respring
Step 3: Open up iFile and go to /private/var/mobile/Containers/Bundle/Application/
Step 4: Look for the right app and open its iTunesMetadata.plist
Step 5: Scroll down until you find a long list of versioning numbers
Those are your software (app) version. Copy and paste the one you want to the popup from App Admin’s screen. Then proceed as usual.
Wait for the new application to download on your home screen and open it to see if everything works out fine.
App Admin is still in beta and so some of these inconvenient are unavoidable. UnlimApps says that they’re working on features like auto-update blocking and specific version URL for easier access.
