I was only successful at rooting a phone once years ago and haven't needed to do it since. I have only one need to root my One and that's to enable the tethering that AT&T is blocking. I have no desire to change my phone in any other way. If there's a way to tether without rooting, I'd love to hear it, but nothing I've tried so far works. I would even settle for a USB tether. If I take the leap of faith and root, I want to be absolutely sure that tethering will then work. If it doesn't, it would be wasted time and effort. Advice appreciated.
