Hey @spookcity, as you predicted the P_custom doesn't build direct from branch with Google toolchain (at least for me), but it does build with cherry-picks (for all but your last few P_custom specific changes). Been stable, fast and smooth so far..many thanks for this amazing work!! Just out interest, which toolchain have you been using?I have pushed a P_custom branch to github.....Although I have used a custom toolchain to build mine and cant say for sure if it will build successfully with the stock google toolchain..
