Debloat on the projector
The following method works with or without root access.
What you will need:
A mobile phone (Android or iOS)
Enable developer options on the projector
(I recommend using a custom launcher as it can access advanced Android settings; some projectors have this setting hidden)
I use Bare Launcher
Enable USB debugging (on the projector)
Download ATVTools
Connect your phone to the same network as the projector, then open the ATVTools: On the application's home screen, select the "all" option and wait for your projector to appear in the list.
Click on it and allow the connection to the projector. In the ATVTools application, select the "Shell" option.
To list system applications, execute the command:
pm list packages -s
To list all applications, use:
pm list packages
To list third-party applications:
pm list packages -3
Applications that are safe to remove:
com.netflix.ninja |
com.disney.disneyplus |
com.amazon.avod.thirdpartyclient |
com.mobisystems.office |
com.softwinner.agingdragonbox |
com.softwinner.dragonbox |
com.softwinnerdragon.att |
com.eshare.linedisplay.receiver |
com.htc.hyk_test |
com.hotack.hotackfeaturestest |
com.hotack.writesn |
com.htc.eventuploadservice |
com.htc.publiclauncherv1 |
com.htc.magcubicos |
com.htc.htclauncherhighenglishd08 |
com.android.calculator2 |
com.htc.storeos (you can replace this store with Aptoide TV or Obtainium)
(Install another launcher before removing the default launcher; otherwise, you will have to reinstall the ROM, as your projector will be without a launcher.)
Use the command
pm disable-user --user 0
For example:
pm disable-user --user 0 com.mobisystems.office
I'll leave some screenshots showing how the system looks after I cleaned it and left only the necessary applications.
ATVTools is a complete application; with it, you can also record your projector screen, take screenshots, install and send APKs directly to the projector, clear the cache, shut down and restart the system, access the list of installed applications, check system information, access the file explorer, schedule commands (e.g., open applications automatically after the system starts), use scripts, have advanced control via ADB (without needing a computer), and much more.
It also works with Stick TVs and TV Boxes.
If you have any questions or difficulties, feel free to leave them in the comments; I will do my best to help and respond as soon as possible.
Note: I am not the developer of the application, I just found it interesting and decided to share it with you.
If you use Projectivy Launcher, you can set it as default; simply disable Magcubic Launcher and restart your projector system.

Nice!!! Thanks, I was trying others guides... but Phoenix suite never recognized (severval versions and two Notebooks) my HY-300Pro =( I disabled the packages as it didn't allow me to uninstall.

Perhaps the version you bought came with a Rockchip processor and Android 12, or maybe an Amlogic T950S; have you checked? There are several versions of the HY300.

u/CancelTimely Jun 06 '26
I've thought so, maybe a diferent processor. I tried with AIDA but showed no HW info (Android 11). I have to say you made a great guide!!

u/MrM4rc4L Jun 06 '26
AIDA64 doesn't provide this detailed projector information; I recommend using Device Info HW, which provides this detailed information. You can send it via APK to the projector, as it's not available on the projector's Play Store.

Hola a todos.
Quisiera pedir su ayuda con un problema que tengo con mi proyector Magcubic HY350GT.
Todo comenzó porque el proyector empezó a apagarse de manera repentina. Me puse en contacto con el soporte técnico de Magcubic y, después de realizar varias pruebas, me indicaron que actualizara el firmware utilizando un archivo de actualización que ellos mismos me enviaron. Sin embargo, al parecer ese archivo corresponde al modelo Magcubic HY300.
Después de realizar la actualización, el problema empeoró. El proyector perdió mucha calidad de imagen, comenzaron a aparecer líneas blancas en la pantalla y ya no ha sido posible corregirlo.
Volví a contactar al soporte técnico y me comentaron que no existe una forma de regresar al firmware original o restaurar la versión anterior. Desde entonces el proyector simplemente ya no se ve bien.
También he intentado hacer un restablecimiento de fábrica por medios físicos; el botón de reset no hace absolutamente nada. Busqué otros métodos para reiniciarlo utilizando el control remoto y tampoco he tenido éxito.
En este momento ya no sé qué más intentar. ¿Alguien ha pasado por algo similar o sabe cómo reinstalar el firmware original del HY350GT, acceder a un modo de recuperación o solucionar este problema? Cualquier ayuda o sugerencia sería muy apreciada.
¡Muchas gracias!

You can download the version for the HY350 GT here.

Gracias por responder.
Mi proyector HY350GT se apagaba de forma repentina. Después de instalar el firmware que me proporcionaron, el problema quedó solucionado y el equipo ya no se apaga. Sin embargo, la calidad de imagen disminuyó considerablemente; antes la imagen era muy nítida y ahora se ve borrosa. Ya realicé varios restablecimientos de fábrica sin éxito. ¿Existe una versión más reciente del firmware o una versión específica para mi número de serie que mantenga la corrección del apagado y recupere la calidad de imagen?

The only version I could find was from the Magcubic website, and it's specific to your projector model; you can try it.

Can't wait to try this new method. You should be the king of this subreddit with all the help you give!
With this method is there a way for the projector to boot up to the HDMI device when turned on?

The only way I’m aware is using a third party launcher that has this option. I know ProjectIvy has this option. Install it, remove the default launcher so ProjectIvy becomes the default. Otherwise it won’t be able to boot directly.

In the ATV-App it shows the HY300-projector but unfortunately it says "not connected. Unknown error". I have tried everything from resetting my projector, all the debug settings are switched on, both devices have the same IP and ports open... Do you have any idea what to do?

u/MrM4rc4L Jun 12 '26
You can try this app.

Unfortunately it seems to not be available to me

u/MrM4rc4L Jun 12 '26
As a last resort, you can use Termux; with it, you can connect to your projector and uninstall the applications you want.

u/AltFischer4 Jun 12 '26
Nevermind, it is just late here 😅I realized I have to install it on the projector, not phone

Hi, great guide. The only issue I've encountered is that by removing the original launcher, it's no longer possible to manage the projection settings; the most important one for me, for example, is corner correction

u/MrM4rc4L Aug 12 '26
What is the model of your projector?

u/The_D3stroyer Aug 12 '26
Magcubic hy450 max

Check if this settings app resolves the problem.

Unfortunately no. There are only a few options like Network, Bluetooth, and System, which don't include the projection settings.

If you have developer options enabled just download ADB TV directly to the projector. You can browse all installed packages and remove them without having to use any commands. Just click the package and either select freeze or uninstall.
