I have a Cricket branded Motorola Moto G 5G Stylus running Android 11, and I'm trying to disable the system updates. I've already disabled system updates in developer options, but it still forces updates - I can delay the update for ONE day, and then it forces the update with absolutely no way to stop it, and no more delays. You get 24 hours and then it forces it.
I tried using ADB to directly disable the system update apps. There are two, both labeled "Cricket Software Update" with package names com.motorola.android.fota and com.motorola.ccc.ota. I disabled com.motorola.android.fota, but when I try to disable, uninstall, or clear com.motorola.ccc.ota, ADB gives an error "Cannot disable a protected package" or "Failure: package is protected."
I use this phone for reliability testing, and forced restarts for system updates break that. Not to mention the updates themselves often break functionality of other apps or system features. I don't need updates, don't want updates, so how do I disable system updates on my Motorola Moto G Stylus 5G? Or, how can I disable protected system packages/apps with ADB?
