Yep you read correct, re-root. I recently bought an already rooted NC, it was a decent price. I don't know how it was rooted. Are there even different methods? When I rooted my phone, I learned a lot that helped me to understand updates, roms, themes, etc. I am considering rooting the NC again to get a feel for what is going on. Any idea if rooting an already rooted device could do it harm? If not what the preffered method, once again if there is more than one. Thanks in advance for any suggestions.
