UART Pinout

The NeoTV features a serial output that can be accessed. In the initial software version, this dropped directly into a root shell.

Using a UART/TTL Adapter (3.3v), connect wire for wire to the pinout below.

Settings are 115200 8n1, no login or password. You will be dropped to a root shell after bootup

PrimePwn (Root)

PrimePwn is the name of our automated root process. It works by leveraging a debug service that is called "testmode", which checks for a USB drive with a file named “.testmode” containing the magic string “testmodemark”. The system then checks to see if the file contains the magic string “testmodemark”. If the system finds the file, it sets the “persist.radio.testmode.enabled” property to 1 and reboots. Then, if the device detects this property as 1 upon boot, it attempts to copy and then extract a file named “test_mode.tgz” from the USB drive to /tmp/. After extracting, the system tries to run a sh file named “/tmp/test_mode/test_mode.sh”. Assuming we set the permissions correctly this file will allow us to run the payload of our choosing as root.
