Can KingRoot Brick my Nexus 9 and HTC One Hello Android Enthusiasts,

I was wondering if KingRoot can potentially brick my HTC One and Nexus 9. I have not rooted either yet for my warranty is still active. If either is bricked, is there a way that it could possibly be recovered? If possible, could you please provide me with some statistics or percentages regarding the likeliness of one of these devices becoming bricked? Here are a few more specifications about my devices:

HTC One M8 Harman Kardon Edition from Sprint

HTC Google Nexus 9 (No carrier, WiFi)

Thank you in advance.

Regards,

Ani
As usual, the answer is:  any attempt to modify O.S. files can brick your phone. But you can try to root your phones.  Just make sure you made a full backup of your phone software (not only /data), including boot.img and other sensitive parts of O.S.(system.img and so), and keep those files safe saved on your computer (so you can reflash your phone in case something goes wrong). Before attempt to root your device, the oem boot loader must be unlocked. The apk of KingRoot in itself does not produce to much harm on O.S. It just install a necessary su  binary to allow getting root access to system, and also some other files. The primary scope of any rooting tool is indeed, placing su somewhere in /system/bin and symlink it (maybe) in /sbin. If you don't know about flashing your device, don't ever try to do things you actually don't master.
