Motorola's software-update client, com.motorola.ccc.ota, posts update reminders through notification channels that are marked fixedImportance at the framework level. That means:

• Disabling the app with pm disable-user does not stop it — something still relaunches its process in the background to push the notification.
• Demoting or blocking its channel from Settings, or from another Xposed module that only patches the app's own notification calls, does nothing, because the importance lock is enforced by NotificationManagerService in system_server, not by the app itself.

This module kills com.motorola.ccc.ota's process the instant it starts, before it can do anything — including post a notification. No root shell command, Magisk module, or app-side Xposed hook can reach this chokepoint; this one hooks the module loader itself.

• Kill on sight. The moment the target package's classloader is ready (meaning its process just started), the process is killed outright. No UI, no delay, no reliance on pm disable.
• System-layer block (where supported). On frameworks that allow module injection into system_server, it also hooks NotificationManagerService's notification-enqueue entry point and silently drops anything posted under the target package name, as a second layer independent of whether the app's own process is even alive.

• A rooted device with an LSPosed-compatible framework that supports the modern libxposed API 102, such as Vector or a recent LSPosed.
• A Motorola device shipping com.motorola.ccc.ota (most Moto phones since Android 9).

1. Download the latest APK from Releases and install it.
2. Open Vector or LSPosed, enable Moto OTA Killer, and scope it to:
   • com.motorola.ccc.ota
   • System Framework (android/system), if your framework exposes it — optional, see note above.
3. Restart the device once so the hooks load.

There is nothing to open afterward — this module has no UI and no launcher icon by design. It runs silently in the background.

Verified means the target package's process was observed being killed within milliseconds of starting, confirmed via logcat on the device and Android version listed. Other Motorola devices and Android versions should work identically since the hook targets a package name, not device-specific code, but are unverified. Please open an issue with your device and Android version if you test one.

• The system-layer notification block does not install on frameworks that don't allow system-server injection for modules (see note above). The kill-on-sight hook is unaffected by this and is the primary mechanism.
• If Motorola ever renames the package id, this module will need an update to match.
• This only targets com.motorola.ccc.ota. It does not touch any other Motorola service.

You need JDK 17 or newer and the Android SDK with platform 36.

Moto OTA Killer is free and open source under the MIT license. There is no closed part, no tracking, no account, and no UI to build trust around — read the one hook file, it does exactly what this README says.

Issues and pull requests are welcome. Please read CONTRIBUTING.md first.

This module is for owners of their own Motorola device who want to stop an unwanted background service. You are responsible for how you use it, including any effect on receiving genuine software updates you may still want. The software is provided as is, without warranty.

• libxposed for the modern Xposed API.
• LSPosed and Vector for the frameworks it runs on.
