Root Any Android Device Using Root Transmission with USB On-The-Go [How to]
Root Transmission allows one-click rooting on any Android device using another pre-rooted Android device with USB OTG support

Rooting any device is essential to get root access to the device and to be able to install third-party root-based apps, custom ROMs and system tweaks. Achieving root access has become much easier and simpler, thanks to factory unlocked bootloaders offered by Samsung, HTC and Sony on their latest smartphones and tablets. Despite the privileges offered by device makers, some Android phone and tablets end up getting locked or permanently bricked due to root script errors.

Root Transmission app from XDA Developers member wchill, offers rooting capability on any Android device using another pre-rooted Android phone or tablet. This is accomplished with the use of a USB On-The-Go (OTG) cable for connecting the two devices.

Root Transmission is the only app capable of rooting other devices from a pre-rooted device. The app is reportedly inspired by Kos's p2p-adb hacking toolkit (available here) and presents a very simple interface with just two buttons, root and unroot. Users just need to connect a non-rooted Android device with another pre-rooted and OTG supported Android device using the USB OTG cable, and then root the device. The app offers a complete ADB (terminal) to view the progress of rooting in real-time.
