# [Guide] How to Downgrade apps on AppStore with iTunes 12.6.5 & Charles Proxy (no Jailbreak). # Table of contents [I. Notes](#Notes) [II. Requirements](#requirements) [III. Let's get into it](#getintoit) ## 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](https://tools.lancely.tech/apple/app-search). See more info in pictures below: - Pic 1, 2, 3 ## 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. - pic 4 ### 2.
