I have a sabresd based reference board and I have ported android O from official source.
I am facing a problem that none of the service works. All are getting killed.
In my case adb is not present as there is no usb port
below I am pasting the logs

mount -o rw,remount /system >>>>>this works
[ 174.751226] EXT4-fs (mmcblk0p3): re-mounted. Opts: data=ordered

I tried various commands such as

chmod 777 /system/build.prop
mount -o rw,remount /system >>> this works but still no use
mount -o remount,rw /system /system
mount -o ro,remount /system
mount -o rw,remount /userdata
mount -o rw,remount /mnt/sdcard
mount -o rw,remount /dev/block/mmcblk0p10 /userdata

I get this error on trying to mount userdata

mount: '/userdata' not in /proc/mounts

Can any one help me, what is wrong here?
