Our project requires rooted Android environment, and we want to achieve this from an installer app.
The installer app is installed and started, and before it downloads other components and locks down the system we need to root it if it is not already rooted.
We dont want to use any external HW like a pc.
Target systems: 4.2-4.4, any HW (tablet)
Applicants need to describe in a few sentences how would they achieve this.
