I should be getting my Fi SIM card today... so I'm looking at a lot of Project Fi threads as well as Nexus 6P threads on any and all subjects. Back in the old HTC Thunderbolt days (the beginning of LTE) I rooted and flashed a lot of different ROMs. Since then, not so much.
Question: Why root? I've read other threads and most will say their is some possibilities you might be less secure and open yourself to some that might steal your data or personal information. Are you wanting to root to flash a different ROM? Are you rooting to do something special that you could not do if it was not rooted? What's the fascination with rooting now-a-days?
