I have 2 of these with Android 9. A 50 and a 60. They use the android home launcher and so display ads, etc.
Specs:
Mstar M7322
2gb Ram
4GB storage
Mali GPU
Right now:
Adb can be entered over wireless. Most apps can be user disabled/uninstalled.
App List: https://pastebin.com/GL8b00s6
Apps to Disable: https://pastebin.com/ngM3Gy8g
You can use termux with ADB addon to use ADB right from the TV with BT keyboard.

Android launcher contains the input switcher so hard to replace but this one works: https://forum.xda-developers.com/t/app-android-tv-projectivy-launcher.4436549/
Can only use VPN based firewall. Can't use my VPN.
Can't be trusted on network.
Remote has a microphone (hi Orwell!).
Bromite/VLC/Kodi/etc all run.
No [email protected] 4:4:4 beyond 8bit.
Issues:
* USB adb works with a male to male cable. Bought one on ebay.
* There is no service jack/socket or service manual I could find to get the bootloader console.
* On reddit someone used a raspi zero?
https://www.reddit.com/r/AndroidTV/comments/pyo4sk/_/hfqvua9 * Cannot list MTD partitions on ADB without root.
* Supposedly unlockable from bootloader/fastboot but beware:
https://forum.xda-developers.com/t/android-tv-stuck-on-black-bootloader.3803695/
* No firmware updates to dissect.
Service Mode (Mstar Service Menu):
Menu -> Sound -> Advaned -> Balance -> Type '1' '9' '6' '9'
How to disable an app without root:
Board info?!
In app manager system info the mainboard identifies as MSD6886. This one is slightly different in terms of port layout as if it was the upgrade version. But that board has a service manual and bootloader/layout stuff applies. https://www.manualslib.com/products/Hisense-Msd6886-10481497.html
The uart on that board is the headphone jack which isn't present on this TV. Maybe it has to be soldered.

Has anyone gotten any farther with this or any other mstar based TVs? Tried more malwareish programs like kingroot? What's worth trying next?
If the bootloader can be unlocked a backup could be made and it might just be a matter of adding magisk binary for all of that receiver/service disabling goodness.
Maybe one day we can compile a rom for it.
