Good day sir, I cant find the Developer options after i use framaroot with my tablet, I tried factory reset, Recovery data wipe and tapping the build number, it always say, "No need, you are already a developer", i want to open the USB debug to root my device e to back-up my firmware before I flash new firmware..
