Thanks to a new beta tool created by Justin Case, the Moto X on Verizon and AT&T running the new Android 4.4 update has been rooted. The process isn’t necessarily as simple as it has been in the past, but this method installs a “backdoor” to help regain root and also requires a downgrade in bootloaders to “re-expose a vulnerability.” There are tons adb commands involved along with the use of Cydia Impactor to open a Telnet session. Again, it’s not pretty or anywhere near a 1-click option, but at least you have an option.
You’ll need to be running 100% stock in order to perform this. Proceed with some caution, as you should every time you start messing with bootloaders.
For those who have already gone through this method, be sure to pop into the comments to let interested parties know how it went. Also, feel free to provide help as needed.
