Confirmed - works fine on 10/23 with lk 9.15 exp. Will continue to test other builds.
Works fine with 10/26 and lk 9.15 exp
okay, issue appears to be with last lean kernel build 9.15 exp as hotspot/tethering works on 10/30 without this custom kernel.
If you try to flash all three together, it does not work. Flash rom and gapps first, let set, then reboot and install lean kernel and it works.
