1) mounted as read-only
2) some files have the "immutable" bit set on the ext4 file system. #chattr -i
file will remove the immutable bit
3) since KK firmware Huawei applied a new security mechanism by which the kernel seems to discard any modification done to /system even when it's remounted as RW. With this mechanism any change is rolled-back by the time /system is remounted as RW even after a reboot.
From the shell command line I have found a way to solve the first two but I still have no clue of how to solve the third one. Does anybody have any clue on how to solve it?
