# I. Notes
|
||||
- **iTunes 12.6.5 only works on Windows**. Apple killed iTunes 12.6.5 on macOS. Even if you manage to get iTunes 12.6.5 on your Mac, the download feature will not work.
|
||||
- The Guide seems complicated, but it's very easy to follow. Plus, you only need to do Step 1, 2, and 3 once (There are 5 steps in total).
|
||||
- Jailbreak is **NOT** needed. Since the iPA comes directly from iTunes, it's encrypted and can be installed directly, no sideloading. The IPA is 100% legit!
|
||||
- You can get any version of any apps, as long as that version is still **available** on AppStore.

|
||||
- **A Windows machine**: Windows XP/7/10/11 are supported. You can also use a VM Windows.
|
||||
- **Charles Proxy**: I use version 4.2.7 but I don't think it matters (No need to _crack_ Charles Proxy). [Download here](https://www.charlesproxy.com/assets/release/4.2.7/charles-proxy-4.2.7-win64.msi)/ [back up](https://www.dropbox.com/s/nrp4obp0ctcwn9e/Charles%20Proxy%204.2.7.rar?dl=0)
|
||||
- **An Apple ID for iTunes**: Use a spare ID if you like. Keep in mind that if you switch to another ID, you'll need to re-do the process from [Step 3](#step-3-create-the-breakpoint).

# III. Getting Started
|
||||
## Step 1. Preparing
|
||||
- Nothing special about Charles Proxy so I'll focus on iTunes.
|
||||
- After you install iTunes successfully, 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 to iTunes with your prepared Apple ID: **`Account > Sign-in`**.
|
||||
- The **`Build version number`** (or `Build Number`) of the version you want to downgrade:
|
||||
- Method 1: You can get the `Build version number` of most apps on AppStore from [ipaarchive](https://ipaarchive.com/) or [Tool Lantency (backup)](https://tools.lancely.tech/apple/app-search).

|

- Method 2: Ask a jailbroken user who has AppStore++ installed get the `Build version number` for you.
|
||||
- Method 3: Look at the `buyProduct` content and search for `softwareVersionExternalIdentifier`, the very bottom line is equal to the latest version, keep trying until you succeed.
|
||||
- Method 4: Almost the same as method 3. See [here](https://github.com/qnblackcat/How-to-Downgrade-apps-on-AppStore-with-iTunes-and-Charles-Proxy/issues/8#issuecomment-1272240225).

### Step 3.1. Open iTunes & Charles Proxy
|

|
||||
|

### Step 3.2.
|
||||
### Step 3.2.
|
||||
- Search for the app you want to downgrade. I will get the IPA of **Facebook v161.0** as an example.
|
||||
- If the app is removed from AppStore, but still available in your **Purchased tab**: it can be found in **`Account > Purchased`**.

|
||||
### Step 3.4.
|
||||
- Now, go to **Charles Proxy**, we'll see a list of domains. Find a domain that has a form of **`p**-buy.itunes.apple.com`**, **`**`** is two-random numbers. As you can see in the picture below, mine is **`p31-buy.itunes.apple.com`**. Right-click on it and select **`Enable SSL Proxying`**

### Step 3.5. Enable the Breakpoint
|

- Go back to iTunes and download Facebook again. This is still not a version we want, so we'll delete it.

||||
- In **Charles Proxy**, you'll see a new **`p31-buy.itunes.apple.com`** address **with the blue icon at the top of the line**. Expand this address to **`buyProduct`**, and then follow the pictures:

|
||||
- In some cases, the **Breakpoint popup** can appear twice, simply edit the current `Build Number Version` like above one more time and you're good to go.

# IV. FAQ
|
||||
## 1. I can't see the Build number of the version I need on neither ipaarchive nor Tool Lantency?
|
||||
- The easiest way to get the Build version number is to ask a jailbroken user who has AppStore++ installed. Just tell them the app & the version you need to get.
|
||||
- If you have nobody to ask, you could try this way. It will take a while depending on your luck. https://github.com/qnblackcat/How-to-Downgrade-apps-on-AppStore-with-iTunes-and-Charles-Proxy/issues/8#issuecomment-1272240225
|
||||
- Still can't find the Build version number? Well, open a new issue, I will help you. You must include the AppStore's url of the app.

|
||||
|
||||
## 2. Can I share the IPA with my friends?
|
||||
- **Absolutely yes!** However, you have to give them **the Apple ID you used to get the IPA**. Why? Because the first time they open your app, they will be asked to enter the purchased ID.

- Don't want to share your main account? Use a clone Apple ID then.
|
||||
|
||||
## 3. Can Apple revoke my IPA?
|
||||
- **No, they can't!** If you use iOS long enough, I'm sure you remember that time when we can download IPA directly from iTunes. Our IPAs came from iTunes just like an app from AppStore. Apple can do nothing about it.

||||
## 4. Can the app be able to receive push notifications?
|

|

|
||||
- Yeah, you can install the IPA using Filza.
