So you are at a friend’s house, up there to take a look at his (or her) new Android device and help him root it. However, instead of downloading a tool or utility, you whip out your own rooted Android device and use it instead to root his device by connecting one device to the other. It would be nice to be able to do that, right? Well, turns out that you can.

XDA forum member wchill has come up with Root Transmission, an app for Android devices that lets you root (and unroot) other devices, without the need to download or install anything on, or even use, a computer. The app works by transmitting the necessary files via USB On-The-Go (OTG) functionality by connecting one device directly to the other via an OT cable and running the necessary scripts (the same scripts that one-click tools use to root devices from a computer).

There are a few prerequisites, however, for using Root Transmission. First, the device that you are using to root an unrooted device needs to support USB OTG, which exists on almost every high-end smartphone but might not be supported on mid-range and low-end ones. Second, you need to supply the necessary one-click root scripts for the device you want to root. Oh, and you must also have an OTG cable in order to connect the two devices together.

Also, devices like Samsung’s Galaxy phones that need a custom kernel to be flashed to root won’t be supported, as Root Transmission can’t perform those operations, but thankfully, there are quite a few devices out there that don’t require a kernel flash and are easily root-able, which should work with Root Transmission.

Root Transmission is no doubt a very useful app that will make the process of rooting Android devices quite easy. It is currently in its early stages and can be downloaded from the source page on XDA, where you also find further details on how exactly the app works.

Do let us know how it works if you try it!
