Hmm if this is your first time rooting
I had two thunderbolt (mine and my gfs), one samsung charge , and the xoom tablet and couple of old iphones. So i went through many roots, jailbreaking etc..
I gotta say, hands down, the rezound is the trickiest,however, far form impossible due to the amazing devs support.
You really need to start with a simple phone that has s-off (like my loyal tbolt). after you get the complete gist of rooting, you have to back to school to understand the difference between unlocked bootloader and s-off.
Just to get the ota update, i spent close to one week just reading endless forums and user reports. When i did it, it worked flawlessly, but i still have a residual migraine from the amount of info i had to really understand.
of course now that i accomplished it, it seems like cake, which make me get to the next point; just because someone says its easy, it doesent mean it is.
Point is, if your a noob(i, in no way, want to insult you, just watching out for you), find a nice person on this forum that accomplished this and Pm them every step of the way. This community has matured and developed to fight against one enemy, the big red, and all their ways trying to hinder us from getting 100 % of our money.
Bottom line: If this is your first root, or if this is your first s-on unlocked bootloader root, spend at least 2 weeks to understand EVERYTHING you need to do, but without a doubt, you will only unlock this beast's potential when you root and unlock it, only then will you see why developers are jumping ship as well as old g-nex users to this phone
