Hey all.

I just purchased a Mi Box S for a family member and am hoping to make the device as simple to use/senior proof as possible.

I wanted to follow this post to change the default launcher to something very simple to use, like ATV Launcher or TVLauncher, but when I connect the laptop and Mi Box via a USB Type-A to Type-A cable (male-to-male) I do not get any message on the PC about the Mi Box being recognized or asking for device drivers to be installed. I was sure to enable developer mode on the Mi Box.

Can anybody assist me in changing the default launcher for the Mi Box S?

Thanks!

Edit - So I think I'm connected to the Mi Box now. I think I just needed to enable "USB debugging" in the Settings menu of the Mi Box. But now when I attempt to enter a command, I'm getting the message

C:\Users\****\Desktop\mi box launcher\minimal_adb_fastboot_1.4.3_portable>adb shell
oneday:/ $ pm hide com.google.android.leanbacklauncher
Error: java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USERS.
1|oneday:/ $ pm hide com.google.android.tvlauncher
Error: java.lang.SecurityException: Neither user 2000 nor current process has android.permission.MANAGE_USERS.            

I'm also not totally sure if I should be attempting to hide leanbacklauncher (Is this outdated and no longer used?) or tvlauncher .

Any help is appreciated!
