android - Unable to boot freshly built CyanogenMod 13 -

-

after playing around latest build of cm device (12.1), decided try , build first rom. got linux, synced sources 13, etc. (my device tree here.)

i had grapple few audio-related build errors before got build. (if makes difference, commits had revert related pcm audio offloading.)

now, when try boot rom, reboots recovery without displaying boot animation. looking @ /proc/last_kmsg, problem seems selinux:

... [    4.340084] init: (initializing selinux enforcing took 0.51s.) [    4.349071] type=1400 audit(1468237723.015:4): avc:  denied  { fowner }  pid=1 comm="init" capability=3  scontext=u:r:kernel:s0 tcontext=u:r:kernel:s0 tclass=capability permissive=0 [    4.349387] init: selinux: not set context /init:  operation not permitted [    4.349506] init: restorecon failed: operation not permitted [    4.349699] init: security failure; rebooting recovery mode... [    4.350353] sysrq : emergency remount r/o (triggered init:1) [    4.350581] emergency remount complete [    4.350889] reboot - triggered task: init (1:1) ...

i'm not familiar selinux apart fact makes system modifications lot harder, i've seen, both device-specific , general init.te files in android source allow init use fowner capability.

i've tried:

  • modifying sepolicy file making init domain permissive
  • rebuilding entire rom permissive init; in init.te
  • commenting out restorecon /adb_keys , restorecon_recursive /mnt in init.rc
  • rebuilding device kernel extra_cflags += -dconfig_always_enforce=true
  • searching solution on google - person on xda had exact same problem me subsequent posts him/her did not yield progress or solutions on matter

none of them made difference, basically, i'm fresh out of ideas.

what doing wrong?
