My problem regards the mount of the /system directory of Android, particularly when I try to do it with my Sony Xperia L.
I try to use this command after get su permission
mount -o remount,rw /system
initially it seems to work but after few second the phone reboots. The same command on Nexus 5 works.
I try also these commands that I found here but the result is the same:
mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p9 /system
mount -o rw,remount -t ext4 /system
The phone is rooted and I get su permission before make it.
