Currently I have access to ADB root and also can modify the system folder or even place files inside the system folder but I want to grant Root Permission to my Application which the OS is not allowing. It also has SU placed in xbin folder but when I install SuperSu it says root undetected.
The commands that I try to gain root access to system were
adb root adb disable-verity adb reboot adb root adb remount
These all commands execute with success and I have access to modify the system folder but after trying everything I am still not able to grant SU access to my Application.
Even I tried to flash TWRP but the board is not entering Bootloader with the following command.
adb reboot bootloader
