* "Android".

I tried to install the boot samsung s3 by the recovry system, but Still I have a error msg:
*
"Signature verification failed.

"FX was not ble to obtaine root/superuser access to perform this operation. Ensure this device is able of root access and That You Have Granted root accessto fx file explorer installed superuser using your application."
