That didn’t take very long, did it? Shortly after the whirlwind of fury that was Verizon customers yesterday, the development community came through and obtained root for the Verizon Galaxy S III—with no help from Verizon, we might add. The root method came just a few hours after it was discovered that conventional root methods wouldn’t work due to a security check when flashing unsigned boot and recovery images.
XDA Senior Member invisiblek posted the root method for users, but credit also goes to a number of other users and developers including Team Epic. With Verizon customers settling down for the long haul, it wasn’t expected to find root and recovery on the device so soon.
The root method still follows the basics of the root method for the other U.S. variants. Users flash a rooted system image to obtain root. And once rooted, users can push a custom recovery image via ADB. Obtaining root is said to take some time, as it takes Odin around 10 minutes to flash the rooted system, so if it seems like something is wrong just continue to wait.
