I’m Moto X xt1060 user. I have saw a link to download mokee pie ROM on my model. It is showing my phone is slot A supported for project treble. But treble check app reveals that there is no treble support in my phone. It is currently running on Android L (5.1). Most advanced ROM available for it is android N. But treble needs minimum android 8. So how it is possible to use the available mokee ROM on download site?
Mokee ROM Moto X - ghost
The normal way to flash ROM is unlock bootloader , install TWRP , flash the ROM.
I suggest you to Google for more information about your device.
