Verizon and AT&T did an excellent job of locking down their version of the Galaxy S 5, preventing any type of root exploit on the device for several months after release. Tons of people put up money for a bounty to get their Galaxy S 5 unlocked, topping out at around $18,000, and today developer Geohot from XDA gets to claim that bounty.
Geohot, known for tons of jailbreak exploits on Apple devices and the PS3, found a vulnerability in the Linux kernel that Android is based on to achieve root access on the GS 5. As a side effect to that exploit, the root method should work on most newer Android devices, including the previously unrootable Galaxy Note 3 and plenty of other devices.
If you’ve got a Galaxy S 5 (or other device you need to root) hit the link to test out the Towelroot app. Let us know how it goes in the comments.
