The following is based on the S50 test, X60 and S40 in my experience is also available as one, one key root article Warning: Because root users can delete the system files, so beyond the delete operation of this post may cause the system to become a brick, it is recommended Users should not delete files at will, and the resulting consequences are not responsible for this. In order to determine that the reader of this post agrees with this statement, I will set the root process as the reply visible, and the respondent will agree to this statement.
