I agree with smeroni68 that the method using TWRP/CWM is pure and simple, because it is running in an environment in which they operate limited processes.
In the case of alireza7991, the Android operating system can be started the process of supervising other processes can lead to conflicts.
This method is useful for the advanced user.
You can make it easier to run scripts, for example, by means of SManager
alireza7991's method is a very interesting option
, but the system is larger by two files: ub [224244 B] and m-a_core [4001 B].
These files files can be potentially dangerous to the system. Any process can find it and can use it.
I will repeat: alireza7991 method is useful for advanced users.
