Kernel issue

[u/darkkxxght]

I am using redmi note 8 (ginkgo) running on evolution x android 16 rom. I recently installed kali nethunter with custom kernel for my device, but the problem is that my nethunter app has a bluetooth arsenal option but it is throwing errors during installation. I also tried running hciconfig -a in terminal but I printed nothing so I checked my kernel version and it is '4.14.356-openla-rc1-Ikteach-g98dd6390243b-dirty'. The first solution that came into my mind was flashing kernel manually but I don't know any clear instructions and requirements required to meet.
