-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-

-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or

-#### Root Requirement
+### Root Requirement
 
-> [!CAUTION]
+The app needs root because of a bug in the Android Bluetooth stack Fluoride/non-compliance of Apple with Bluetooth standards. You must have Xposed installed for the app to workaround this bug and connect to AirPods. 
-> **You must have a rooted device with Xposed to use LibrePods on Android.** This is due to a [bug in the Android Bluetooth stack](https://issuetracker.google.com/issues/371713238). Please upvote the issue by clicking the '+1' icon on the IssueTracker page.
-> 
-> There are **no exceptions** to the root requirement until Google merges the fix.
 
-Until then, you must xposed. I used to provide a non-xposed method too, where the module used overlayfs to replace the bluetooth library with a locally patched one, but that was broken due to how various devices handled overlayfs and a patched library. With xposed, you can also enable the DID hook enabling a few extra features.
+[https://issuetracker.google.com/issues/371713238](https://issuetracker.google.com/issues/371713238)
 
-## Bluetooth DID (Device Identification) Hook
+Please do not comment in the thread. The issue has already been resolved and should be available in Android 17 for all devices. 
 
-Turns out, if you change the manufacturerid to that of Apple, you get access to several special features!
+However, if you are using ColorOS/OxygenOS 16, Android 16 QPR3 on Pixel (ensure you're on the latest Play system update), you don't need root for most features.
 
-### Multi-device Connectivity
+> [!IMPORTANT]
+> This workaround with Xposed is not guaranteed to work on all devices.
 
-Upto two devices can be simultaneously connected to AirPods, for audio and control both. Seamless connection switching. The same notification shows up on Apple device when Android takes over the AirPods as if it were an Apple device ("Move to iPhone"). Android also shows a popup when the other device takes over.
+Features requiring the VendorID hook will still require root. These features include customizing transparency mode, setting up hearing aid, and use Bluetooth Multipoint.
 
-### Accessibility Settings and Hearing Aid
+### Troubleshooting steps for common errors
+- Ensure the correct scope is set in LSPosed/Vector.
+- Ensure there is no root-hiding module preventing the hook from loading on the Bluetooth app.
+- Restart your phone after confirming the scope.
 
-Accessibility settings like customizing transparency mode (amplification, balance, tone, conversation boost, and ambient noise reduction), and loud sound reduction can be configured.
+### A few notes
 
-All hearing aid customizations can be done from Android, including setting the audiogram result. The app doesn't provide a way to take a hearing test because it requires much more precision. It is much better to use an already available audiogram result. 
+- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, loud sounds are not reduced.
-
-To enable these features, enable App Settings -> `act as Apple Device`.

-#### A few notes
-
-- Due to recent AirPods' firmware upgrades, you must enable `Off listening mode` to switch to `Off`. This is because in this mode, louds sounds are not reduced.
 
 - If you have take both AirPods out, the app will automatically switch to the phone speaker. But, Android might keep on trying to connect to the AirPods because the phone is still connected to them, just the A2DP profile is not connected. The app tries to disconnect the A2DP profile as soon as it detects that Android has connected again if they're not in the ear.

+# Changing VendorID in the DID profile to that of Apple
 
-[![Star History Chart](https://api.star-history.com/svg?repos=kavishdevar/librepods&type=Date)](https://star-history.com/#kavishdevar/librepods&Date)
+Turns out, if you change the VendorID in DID Profile to that of Apple, you get access to several special features!
+
+You can do this on Linux by editing the DeviceID in `/etc/bluetooth/main.conf`. Add this line to the config file `DeviceID = bluetooth:004C:0000:0000`. For android you can enable the `act as Apple device` setting in the app's settings.
