Issue:Hello, I need your help. My device is leeco max2.

Since last week I have been learning how to compile my own mobile phone on github. The kernel source code I use is the latest version of lineageos.
I follow the nethunter official github instructions after the kernel source code modification is completed, the device is flashing, but after booting, the external wireless network card does not work, and the mobile phone flashlight does not work, my external wireless network card is tplink-wn722 V1.
I want to ask you to help me,

1. In addition to the core settings in the nethunter official github file, I also need to set which options to set.
   2: Do I need to go to download the relevant hardware driver after I set up the kernel, where is the driver downloaded? How to build a driver to the kernel?
   3: If you can, please help me build and add leeco max2 device kernel and device support.
   Thank you.
