As usual, the first thing device owners strive for when a new device is released is root access. Without it, more than 90% of the things we do around here wouldn’t work. So when a device gets root, it’s much like a welcome party courtesy of our developers. The LG Optimus 4X HD, which was released a little more than a month ago, has received not only root, but recovery as well.
For root, XDA Senior Member alexp999 posted the tutorial. XDA Senior Member Dexter_nib posted the tutorial for custom recovery. Combine both, and you have the freedom to do pretty much whatever you choose to do.
The root process is a little tedious, but pretty easy. Users must first enable USB Debugging and Install From Unknown Sources, and then install IS11LG_SystemBackupTest.signed.apk to their device. After that, reboot, connect the phone to your computer—this is a Windows only tutorial currently—and run the root script. Once finished, users install SuperSU, remove IS11LG_SystemBackupTest.signed.apk, and rejoice in the rooted goodness. Installing recovery is even simpler, with users installing a single APK to their devices.
