I. Notes

• The Guide seems complicated, but you only need to do Step 1 to 3 for the first time. And there are 4 steps in total.
• Jailbreak is NOT needed. Since the iPA comes directly from iTunes, it's encrypted and can be installed without Sideload. The IPA is 100% legit.
• You can get the old version of any apps on AppStore as long as that version is still available on AppStore.

II. Requirements

• iTunes 12.6.5 - the latest version of iTunes that supports download apps. Download here (directly from Apple).
• A Windows machine: Windows XP/7/10 are supported, not tested on Windows 11 yet.

(Why Windows only? - Apple killed iTunes 12.6.5 on macOS. Even if you manage to get iTunes 12.6.5 on your Mac, the download feature just will does not work.)

• Charles Proxy. I use version 4.2.7 but I don't think it's matter. (No need to crack Charles Proxy)
• An Apple ID for iTunes. Use a clone ID if you like. Keep in mind that if you switch to another ID, you'll need to re-do the procedure from Step 3.
• The Build Number Version of the app you want to downgrade. It is a chain of 9 numbers representing the version of the application. You always can get the Build number Version most apps on AppStore from Tool Lantency. See more info in pictures below:

III. Let's get into it

1. Preparing.

• Nothing special about Charles Proxy so I'll focus on iTunes.
• After you install iTunes succesfully, go to Edit => Preferences => Avanced => Untick Check for new software updates automatically to prevent iTunes from asking for update.
• If you get an error about Library.itl when opening iTunes: Go to “C:\Users\Username\My Music\iTunes\” and delete the existed Library.itl
• Login into iTunes with your prepared Apple ID.
