Hi , i tried many times but no luck . i have to say exploit works on regular files but when i try to replace run-as , device reboots .

@mehraf You probably are unable to write to the /system partition. If that's the case, trying to write run-as will trigger a kernel crash.

@nonnymoose ok but device is rooted with kingoroot . so writing in /system is possible but i guess i can not write on existing /system binaries

nonnymoose commented 7 years ago

@mehraf Kingoroot probably used an OS exploit to gain superuser permissions, then used those permissions to enable writing to the system partition.
