I got 'Could not set capabilities', I think the reason is /system/bin/run-as doesn't have setuid access right.

my run-as running as uid 2000 Could not set capabilities: Operation not permitted setresgid/setresuid failed uid 2000

I think dirtycow successed, but /system/bin/run-as doesn't have setuid access right, so run-as failed set capabilities.

Out of interest which device was this? Galaxy S4?
