I recently noticed that I have a number of cracked apps installed on my iPad that don't exist on any filehosts anymore.
These were the latest versions of certain apps cracked by crackers that aren't on the scene anymore.
An example: I was trying to get Thor Polysonic Synth to work with Audiobus. The only version of Thor I could find (not just on AppCake, but on the whole of the net) was version 1.0.1. This version is not compatible with Audiobus. Thor version 1.1.1 was released and is compatible with Audiobus. Unfortunately, all the links for 1.1.1 are dead everywhere.
I have cracked version 1.1.1 installed on an older iPad. I decided to try and create an IPA myself, from the installed app.
- Find the App folder in Applications. (Lets say "BexN" app)
- Copy BexN.app folder, iTunesArtwork & iTunesMetadata.plist into a new folder called Payload
- Compress the Payload folder into a ZIP
- Rename the ZIP extension to IPA
- (Don't forget to rename the file and give credit to the original cracker!)
Now you have a backup IPA of the app that is currently installed, and you can install it on other devices with the IPA file.
I tested this converting an installed app (Thor 1.1.1) on iOS 7.1.2, using the method above, and installing the IPA on a different iPad running iOS 8.3.
Hope this helps !
