Como remover a marca d'água de apps instalados manualmente

Atualizado 2026-10-30

If you use CleanYourTV on your Android TV to sideload APKs or install apps outside the Play Store, your devices may show a watermark indicating tampered system files. This is common when you pull APKs from third‑party sites or build custom firmware like YellowT5. The goal: revert those apps to their original, unmodified state without bricking the box.

CleanYourTV is a well known launcher that gives Android TV users fine control over launchers and package management. But when sideloading goes wrong, the warning banners and missing icons can look like an uninstalled element. In reality, they are just symptoms of modified package data.

What CleanYourTV Does and Why Watermarks Appear

CleanYourTV lets you scan installed packages, clear caches, and remove unwanted launcher packages. When you sideload an APK without using the official Store, the package loses its signed integrity. Some apps install with altered metadata, and the TV’s package manager flags them.

The watermark itself is usually a small label displayed next to the app icon or overlaying the home screen. On stock Android TV, it shows up on the lock screen or through the launcher’s preview window. What you are actually seeing is the result of a modified AndroidManifest.xml or a package that has been recompiled from altered resources.

When you reinstall the same APK from a trusted source and tell CleanYourTV to refresh, the launcher will remove the altered package. That is the core workflow: uninstall the bad build, re‑install clean from a verified APK, then trigger CleanYourTV’s cleanup step.

Tools for Unsupported Uninstallation: What You Need

Most official channels do not support removal of sideloaded packages. You need tools that can delete arbitrary APKs or reset the package store. In the Android TV ecosystem, the most reliable options are:

• ADB (Android Debug Bridge) via a network‑enabled TV, or USB if you attached a computer to the TV’s router port.
• A recovery‑style package remover built into the launcher settings, which CleanYourTV exposes.
• Third‑party package managers that can delete selected apps from /data/app.

These are non‑official tools because Google does not intend consumers to manipulate the system package store directly. The trade‑off is convenience versus platform compliance.

Step-by-Step: Removing Sideloaded Apps Without Losing the Box

1. Connect the TV to your PC and run adb shell pm disable-package <bad-app-id>.
2. Reboot into Fastboot.
3. Boot to recovery or use the Android TV recovery menu to wipe user data.
4. From the command line, delete the APK folders in /data/app/user_0/com.<bad-appname>.apk.
5. Clear the cache and reboot.

CleanYourTV can then scan for leftover remnants. Run a second pass after boot to catch anything that changed during the first reboot.

If you prefer not to open a terminal, the launcher itself has a “Package Cleanup” button in Settings > System > Packages. Select the items to uninstall that you did not install yourself. This uses the same backend CleanYourTV uses under the hood.

Risks and Trade‑offs

Removing system‑level packages incorrectly can leave the TV without some sideloaded content, and in worst cases the system partition can become unstable. Always back up your settings before using ADB. Also remember that once you delete an APK, you cannot easily restore it unless you kept a copy. The watermark removal is worth it when you value a clean, signed interface for privacy and stability.

A short list of what is lost or gained:

• Loss: Access to the manually installed app until you redownload it from a trusted source.
• Gain: A fully clean package store, no tamper warnings, and more predictable system updates.
• Risk: Possible minor boot issues if the replacement APK is incompatible with the current TV build.

Verifying the Clean Result

After the removal, open CleanYour TV again and hit “Scan All”. You should see zero flagged items. If the watermark persists, repeat the scan while the device is connected to a stable Wi‑Fi connection. Sometimes the cached scan data holds onto old entries.

Finally, keep your APKs in a secure folder. Sideloading is powerful, but on Android TV the best practice is to install only from sources that publish the original signed APK and avoid modifying resource files yourself. With CleanYourTV handling the cleanup, you get back a tidy home screen and a TV that stays within the supported package flow.

This guide walks you through removing watermarks from manually installed apps on Android TV using CleanYourTV, so you keep your box clean, safe, and ready for regular updates without fighting ghost entries in the package store.
